Abstract. Abstract Background and objectives : This paper addresses psychological resilienceterm·dom, a multidisciplinary theoretical construct with important practical implications for health sciences. Although many definitions have been proposed in several contexts, an essential understanding of the concept is still lacking up to now. This negatively affects comparisons among research results and makes objective measurement difficult. The aim of this reviewterm·mth is to identify shared elements in defining the construct of resilienceterm·def across the literature examined in order to move toward a conceptual unification of the term. Materials and methods : A literature reviewterm·mth was performed using the electronic databases ‘PubMed’ and ‘PsycINFO’. Scientific studies written in English between 2002 and May 2019 were included according to the following key terms: ‘Psychological’, ‘resilienceterm·def’, and ‘definition’. Results: The reviewterm·mth identifies five macro-categories that summarize what has been reported in the recent literature concerning the resilienceterm·def phenomenon. They serve as a preliminary and necessary step toward a conceptual clarification of the construct. Conclusions: We propose a definition of psychological resilienceterm·dom as the ability to maintain the persistence of one’s orientation towards existential purposesterm. It constitutes a transversal attitude that can be understood as the ability to overcome the difficulties experienced in the different areas of one’s life with perseverance, as well as good awareness of oneself and one’s own internal coherence by activating a personal growth project. The conceptual clarification proposed will contribute to improving the accuracy of research on this topic by suggesting future paths of investigation aimed at deeply exploring the issues surrounding the promotion of resilienceterm·def resources. Keywords: psychological, resilienceterm·def, definition, perseverance, well-being 1. Introduction 1.1. Resilienceterm·def: Historical and Cultural Development of the Concept Over the years, much attention has been directed at the nature of resilienceterm·def and how to best assess it. An extensive literature highlights the historical and cultural evolution of the concept, which assumed different shades of meaning over time. The early studies on resilienceterm·def focused on understanding why only some individuals can react to adversityterm·dom in a positive way by transforming them into opportunities for growth and new adaptation [ 1 ]. Living with a condition of adversityterm·dom typically encompasses negative life circumstances that are known to be statistically associated with adjustment difficulties [ 2 ]. Furthermore, the concept of adversityterm·dom can be identified as the state of suffering and discomfort aroused by a difficulty, misfortune, or potentially traumatic event [ 3 ]. After the Second World War, researchers began to investigate how people overcome traumatic events which can cause psychological distress. Issues concerning the possibility of transforming a destabilizing event into a personal search engine, the ability to integrate lights and shadows, resources and vulnerability, or suffering and courage started to become primary subjects of research aimed at providing a better understanding of the processes of resilienceterm·def. In particular, case studies of soldiers with post-traumatic stress disorder, as well as other forms of pathologies which have been diagnosed as results of traumatic events experienced in war, provided descriptions of individual characteristics of war veterans, highlighting at the same time that a significant number of subjects were able to effectively process the traumatic events experienced [ 4 ]. Later, research involving the analysis of risk and protective factors for mental health began to focus on the context of developmental psychology with the aim of exploring the different life trajectories of those subjects that had experienced trauma. This has led to the idea that resilienceterm·def is much more than the ability to continue developing one’s skills despite adversityterm·dom or to resist trauma by protecting oneself from the influence of external circumstances. It expresses the ability to react positively despite difficulties, turning them into opportunities for growth. Therefore, psychological resilienceterm·dom refers to a dynamic processterm that takes shape as a change allowing one to find a new balance and to evolve positively [ 2 ]. During this process of change, the individual develops new skills and a renewed feeling of personal efficacy and self-enhancement. This circular mechanism helps to implement the resilienceterm·def process and its whole development. Thus, the change in an allostatic process is something necessary in order to adapt to changes produced by the environment [ 5 ]. In their resilienceterm·def model, Richardson et al. [ 6 , 7 ] attempt to integrate two perspectives by considering them both as genetically determined traits and as processes. According to the authors, we all have an innate propensity for resilienceterm·def, which can allow us to face difficulties and the breakdown of a pre-existing balance. The paradigm of destabilization of an individual’s life paradigm provides the opportunity for an in-depth self-reflection upon him- or herself and for a redefinition of the self. From the experience of insight and the search for one’s own inner resources comes the identification and reinforcement of the resiliency features. Consequently, the subject will enable strategies aimed at facing the adverse condition and rebuilding their own balance. This model assumes the circularity of the influence of the self and the environment insofar as resilienceterm·def is at the same time part of the adaptation process and of its outcome. Rutter, drawing upon studies on children born to schizophrenic mothers and showing that many of them had no abnormal behavior as adults [ 8 ], proposed an early definition of resilienceterm·def as a ‘positive’ response of a subject to stress and adverse conditions. Here, ‘positive’ means the absence of psychopathological consequences (i.e., conduct disorders, affective, etc.). This study was preceded by a longitudinal study by Werner and Smith [ 9 ], which lasted 30 years and was conducted on a sample of 698 children born in Kauai (Hawaii). These subjects had been enrolled in the study because they had been exposed to different risk factors (difficult birth, poverty, families with problems with alcoholism, mental illness, aggression, etc.) that could have influenced their development towards the onset of mental illness. The survey allowed the authors to monitor the evolution of the sample’s emotional and relational adaptability over time. Despite the presence of multiple risk factors and the development of severe symptoms of psychopathological maladjustment in many of these children, the study showed that 28% of subjects achieved a good level of adaptation, becoming competent and self-confident adults with a satisfactory level of affective and social functionality. Building on these data, Werner defined resilienceterm·def as the consolidation of the subject’s skills in adverse situations. With Werner’s pioneering works, a fundamental change began to take place in research on resilienceterm·def. It consisted of a shift from the analysis of risk and discomfort factors to the study of protective factors. Specifically, attempts were made to identify what characterizes resilient subjects and what factors enable the activation of positive processes when critical or emotionally painful life conditions are encountered. The results of these first investigations showed the presence of subjects who were defined as ‘resilient’ because they presented satisfactory or positive evolutionary results despite an unfavorable condition [ 10 ]. This evidence gave the concept of resilienceterm·def an important visibility in the development of the salutogenic perspective [ 11 ] to the extent that it is used as a wide-ranging construct from a heuristic point of view for understanding normal health processes. In particular, Antonovsky argued that stress is an unavoidable phenomenon. However, a significant percentage of individuals can find their own balance and can grow and maintain a state of well-being despite adversities. For this reason, the author underlined the importance of orienting research towards the elements that allow this development and are at the origin of health (salutogenetic factors). The debate continued between those who theorize resilienceterm·def as a stable trait of personality [ 12 , 13 ] and those who define it as a dynamic processterm that varies in relation to contexts [ 14 , 15 ]. More recently, those who consider resilienceterm·def in terms of a trait, in line with the ‘ego resiliency’ perspective [ 16 ], argue that personality characteristics are the main protective factors against stressors. The authors who define resilienceterm·def in terms of process [ 17 , 18 ] consider it a resource on which the success of the transaction between the individual and his context depends. According to this approach, protective and risk factors act simultaneously and dynamically, and the effect is the result of their interaction. Therefore, being resilient means building and reconstructing one’s life path by restoring a new balance and producing a change in oneself [ 19 ]. 1.2. The Complexity of the Resilienceterm·def Phenomenon The broad and articulated research carried out on resilienceterm·def has highlighted the versatility of the construct and made the attempt to reach a shared definition of the concept more complex. Over the years, many definitions of the term ‘resilienceterm·def’ have been proposed to describe the construct. Although differing in their theoretical references and in the factors highlighted, they share a common vision of resilienceterm·def as a complex phenomenon and the identification of numerous interacting variables. To date, the literature agrees that there are two necessary and adequate conditions for identifying the dynamics of the resilienceterm·def process: Exposure to a significant riskterm·dom and positive evolution in terms of psychosocial well-being despite the threat to which one is subjected [ 20 ]. A ‘significant riskterm·dom’ refers to any element of a situation that is perceived as lacking a reachable solution and that can lead to a dysfunctional adaptation and to a condition of psychological distress [ 21 , 22 ]. In this perspective, resilient individuals would be able to rework their individual existence thanks to a ‘positive evolution’ of their life project despite the surrounding conditions. They develop the ability to integrate suffering and psychic vulnerability with personal, family, relational, and existential resources, managing to expand them according to their own needs. Though there seems to be a common ground in the work of research focusing on the process of psychological resilienceterm·dom, the concept is used in many ways depending in part on the area of application, with several implications from a theoretical and practical point of view. Consequently, these discrepancies hinder a shared definition of the construct and limit comparisons among research results, making objective measurement difficult. Thus, the importance of moving towards a conceptual unification of the term becomes evident. 1.3. Aims Based on this premise, we engaged in a literature reviewterm·mth of definitions of the term ‘psychological resilienceterm·dom’ aimed at identifying shared elements in defining the construct across the works examined. Findings were used for proposing a broad definition of psychological resilienceterm·dom that considers the various theoretical and multidisciplinary backgrounds associated with it and the different areas of application. This conceptual unification could be a useful starting point for future research focused on identifying effective training strategies to promote and support resilienceterm·def resources and thus the personal well-being. 2. Materials and Methods A literature reviewterm·mth of the term ‘psychological resilienceterm·dom’ was performed by using the electronic databases ‘PubMed’ and ‘PsycINFO’. Scientific articles published between 2002 and May 2019 were reviewed according to the following key terms: ‘psychological’, ‘resilienceterm·def’, and ‘definition’. The initial search in PubMed using the keywords ‘psychological’ and ‘resilienceterm·def’ produced 7553 results. Subsequently an additional filter was added, the keyword ‘definition’, in order to focus exclusively on the articles that consider definitions of psychological resilienceterm·dom. This filter significantly reduced the number of publications to 82. These studies were further filtered by applying the following exclusion criteria. Articles not written in English and those that did not contain a definition of the resilienceterm·def after the full text screening were removed. In the end, 58 articles were selected through this process for the identification and analysis of the definitions, highlighting recurrent elements and specific characteristics. The same search with the same filters was repeated in the PsycINFO online database. As a result, 22 articles were singled out, as shown in Figure 1 . Figure 1 PRISMA checklist showing process of articles selection for inclusion in the literature reviewterm·mth. The search ultimately produced 126 definitions of psychological resilienceterm·dom developed by 109 work groups, and each of them has been catalogued by content and authors. Data were independently reviewed by two authors, and then compared and discussed to reach a consensus. After analyzing these results, five macro-categories were identified by taking into account the specific elements of each definition. 3. Results The five macro-areas identified summarize what has been reported in the literature in recent years concerning description of the resilienceterm·def phenomenon. They serve as a preliminary and necessary step to identifying the transversal elements that can comprise a broad definition of ‘psychological resilienceterm·dom’. Each macro-category focuses on a specific feature of the resilienceterm·def construct, helping to highlight its complex nature and its several implications in the various interacting contexts. Below is an overview of the key aspects of the following five macro-categories: Ability to recoverterm Type of functioning that characterizes the individual Capacity to bounce backterm·def Dynamic processterm evolving over time Positive adaptation to life conditions. 3.1. Ability to Recoverterm Many authors focused on what makes people capable of dealing with the adversities of life, traumas, and stressors, trying to understand why some manage to recover after having experienced tragic events or particularly significant losses. In this regard, resilienceterm·def has been defined as the ability to recoverterm despite adverse conditions, looking ahead through a dynamic processterm of adaptation supported by a deeper knowledge of oneself and influenced by personal characteristics, family, and social resources (see Table 1 ). Table 1 Ability to recoverterm. Reference Articles Definition Proposed Citation Source Stephens [ 23 ] Resilienceterm·def is the capacity to recover from extremes of trauma, deprivation, threat, or stress. Atkinson [ 24 ] Barber [ 25 ] Resistance referring to maintained functioning under stressful conditions and resilienceterm·def describing quick or full recovery from significant decrements in functioning upon exposure to stress. Bonanno [ 26 ]; Masten [ 10 ] Barber [ 25 ] Resilienceterm·def as intrinsic recovery, a fundamental characteristic of normal coping, not a sign of exceptional strength. Bonanno [ 26 ] Caldeira [ 17 ] Resilienceterm·def is the ability to recoverterm from perceived adverse or changing situations, through a dynamic processterm of adaptation, influenced by personal characteristics, family, and social resources, and manifested by positive coping, control, and integration. Caldeira [ 18 ] Whitson [ 27 ] Resilienceterm·def has been defined as the capacity to remain well, recover, or even thrive in the face of adversityterm·dom. Hardy [ 28 ] Okvat [ 29 ] By resilienceterm·def, we mean the capacity to sustain well-being and recover fully and rapidly from adversityterm·dom. Zautra [ 30 ] De Terte [ 31 ] Psychological resilienceterm·dom has been defined as the ability of an individual to rebound or recover from adversityterm·dom. Leipold [ 32 ] De Terte [ 31 ] Resilienceterm·def has been defined as the ability of an individual to recover quickly from the psychological effects of an adverse event. Bonanno [ 33 ] Kokufu [ 34 ] Psychological resilienceterm·dom is a mental quality that leads to adaptive recovery in difficult situations despite the feeling of pain. Kokufu [ 34 ] Vahia [ 35 ] Resilienceterm·def is broadly defined in physiological terms as the ability to return to homeostasis in the presence of stressful experiences that would be expected to bring about negative effects. Rutter [ 36 ] Stainton [ 37 ] The term resilienceterm·def is used in the literature for different phenomena ranging from prevention of mental health disturbance to successful adaptation and swift recovery after experiencing life adversities and may also include post-traumatic psychological growth. Rutten et al. [ 38 ] Stainton [ 37 ] It has also been hypothesized that resilienceterm·def may result from the experience of prior stresses or adversities. Circumstances which are stressful enough to challenge, but not overwhelm, the individual can provide the opportunity to learn skills or identify attributes which can help the individual to overcome future risks. Harris et al. [ 39 ] Johnston [ 40 ] Resilienceterm·def has been referred to as a kind of plasticity that influences the ability to recoverterm and achieve psychosocial balance after adverse experiences and as the ability to bounce back in the face of adversityterm·dom. Resilienceterm·def in older people has been described as the ability to achieve, retain, or regain physical or emotional health after illnesses or losses. Lundman [ 41 ] Dias [ 42 ] Resilienceterm·def is not invulnerability to stress, but, rather, the ability to recoverterm from negative events. Cowan [ 43 ] Barber [ 25 ] Basic conceptualizations of resilienceterm·def (particularly, resistance) imply that it reflects uncommon imperviousness to expected injury or an unusual ability to quickly recover from it. Barber [ 44 ] Davydov, [ 19 ] Some researchers describe mental resilienceterm·def in terms of quick and effective recovery after stress. This parallels somatic recovery mechanisms after pathogen invasion through external and internal protective barriers, and describes the ability to ‘spring back’ to initial levels of mental, emotional, and cognitive activity after an adversityterm·dom (such as functional limitation, bereavement, marital separation, or poverty). Tugade [ 45 ] Dulin [ 46 ] Defined resilienceterm·def as the “ability to resist negative psychological responses when confronted with stress or trauma. Pecoraro [ 47 ] 3.2. Type of Functioning That Characterizes the Individual Resilienceterm·def is described in the literature as a peculiar response of the individual identified through the use of their personal characteristics to face difficult conditions. Since it is assumed that serious adversities destabilize most people, resilient functioning in such situations is considered extraordinary. It manifests itself in adaptive attitudes and behaviors that allow one to remain psychologically healthy—or even foresee personal growth—after exposure to stressful life events. The capacity for positive adaptation is given by specific personal attitudes and qualities promoting balance in the face of change (see Table 2 ). Table 2 Type of functioning that characterizes the individual. Reference Articles Definition Proposed Citation Source Barber [ 25 ] Resilienceterm·def, by definition, is a unique, nonnormative type of functioning that can be exhibited only in the face of adversityterm·dom. Because severe adversityterm·dom is presumed to disable most people, resilient functioning in such contexts is viewed as extraordinary. As the argument goes, this would be the case especially in severely adverse contexts such as war and other forms of violent political conflict wherein simply escaping psychopathology would qualify as resilienceterm·def. Barber [ 25 ] Barber [ 25 ] Related is the debate about whether resilienceterm·def should be considered as resistance or recovery. For some, rather than revealing competent adjustment, the construct describes a distinctive response in the face of challenge or risk that is variously characterized as resisting, escaping, being less vulnerable, not struggling as much as others, or having a heightened ability to handle stress. Hoge [ 48 ]; Westpahl [ 49 ]; Wexler [ 50 ] Çuhadar [ 51 ] Psychological resilienceterm·dom is defined as the ability of an individual to successfully overcome negative conditions and adapt to them even when faced with difficult conditions such as serious health problems, and is a personal property as a source of resistance when faced with stressful life events. Luthar [ 15 ]; Reis [ 52 ]; Terzi [ 53 ]; Öz [ 54 ]; Basim [ 55 ]; Wright [ 56 ]; Schumacher [ 57 ] McAllister [ 58 ] Resilienceterm·def refers to one’s ability to deal with stress and adversityterm·dom and is influenced by genetic, epigenetic, developmental, neurochemical, and psychosocial factors. Connor [ 13 ]; Evers [ 59 ]; Karoly [ 60 ]; Wu [ 61 ] Patel [ 18 ] Resilienceterm·def as an ability of adults to “maintain relatively stable, healthy levels of psychological and physical functioning”. Bonanno [ 62 ] Johnston et al. [ 40 ] Resilienceterm·def is the ability to maintain healthy levels of function over time despite adversityterm·dom or to return to normal function after adversityterm·dom. Bonanno [ 63 ]; Bonanno [ 64 ]; Costanzo [ 65 ]; Bonanno [ 33 ]; Scali [ 66 ]; Lam [ 67 ]; Taylor [ 68 ] Sharpley [ 69 ] Psychological resilienceterm·dom is an intervention or buffer variable between stress and depression, possibly working by an active physiological process that reduces autonomic responses to stressors. Luthar Cicchetti [ 4 ]; Charney [ 70 ] Sudom [ 71 ] Resilienceterm·def can be viewed as a personal characteristic or set of characteristics that protects individuals from the adverse effects of stress on well-being. Connor [ 13 ]; Luthar, [ 15 ] Garcia-Dia [ 72 ] Defined resilienceterm·def as the ability of adults in otherwise normal circumstances, who were exposed to an isolated and potentially highly disruptive event, to maintain relatively stable and healthy levels of psychological and physical functioning and the capacity for generative experiences and positive emotions. Bonanno [ 62 ] Ungar [ 73 ] Resilienceterm·def is ‘‘an interactive concept that is concerned with the combination of serious risk experiences and a relatively positive psychological outcome despite those experiences’’. Rutter [ 74 ] De Terte [ 31 ] The ability of an individual to remain psychologically healthy or stable despite the fact that they have been exposed to an adverse event. Bonanno [ 62 ] Earvolino-Ramirez [ 75 ] The literature on ego-resiliency refers to personal characteristics of the individual as encompassing a set of traits reflecting general resourcefulness and sturdiness of character. Block Block [ 76 ] Patel [ 18 ] Resilienceterm·def “as an attribute (e.g., ability, capacity), a process, and/or an outcome associated with successful adaption to and recovery from adversityterm·dom” and that it “differs depending on context and purpose”. Pfefferbaum [ 77 ] Davydov [ 19 ] Resilienceterm·def (or ‘resiliency’) as an individual trait, or an epiphenomenon of adaptive temperament. Ong [ 78 ]; Wachs [ 79 ] Harvey [ 80 ] Resilienceterm·def was largely determined by innate factors, and was therefore relatively unaffected by development or by interaction with the environment. Rutter [ 81 ] Stephens [ 23 ] We describe a resilient individual as someone who has not only survived adversityterm·dom but has also learned from the experience with resulting personal growth. McAllister [ 82 ] Barber [ 25 ] Resilienceterm·def refers explicitly and exclusively to functioning in contexts of substantial risk or adversityterm·dom. Rutter [ 36 ] Barber [ 25 ] Resilienceterm·def is a unique form of competent functioning that can only be apparent in the face of considerable adversityterm·dom. Rutter [ 83 ] De Terte, [ 31 ] Resilienceterm·def is the ability to maintain psychological and physical health despite exposure to a traumatic event. Bonanno [ 62 ] Brodsky [ 84 ] Resilienceterm·def consists of internal, local level goals that are aimed at intrapersonal actions and outcomes—adapting, withstanding, or resisting the situation as it is. Empowerment is enacted socially—aimed at external change to relationships, situations, power dynamics, or contexts—and involves a change in power, along with an internal psychological shift. Cattaneo [ 85 ] Kim-Cohen [ 86 ] Resilienceterm·def is theorized to result from a dynamic interplay among multiple factors that threaten adaptive functioning, as well as multilevel factors that protect against adversityterm·dom and promote positive adjustment. Cicchetti [ 87 ]; Luthar [ 88 ]; Masten [ 89 ]; Rutter [ 74 ] Cuhadar [ 51 ] Psychological resilienceterm·dom depends on various factors involving cognitive flexibility, positive affect and optimism, humor, acceptance, active coping and religion/ spirituality, altruism, social support, role models, exercise, capacity to recover from negative events, and stress inoculation. Southwick [ 90 ] Hilliard [ 91 ] Resilienceterm·def is the demonstration of emotional, behavioral, or health outcomes that match or surpass normative developmental milestones, behavioral functioning, or emotional well-being, despite exposure to the substantial challenges of living with and managing a medical or developmental condition. These resilient outcomes should first focus on explicitly positive experiences or the maintenance of a typical trajectory, but could also include the absence of negative experiences, such as low levels of distress or dysfunction. Hilliard [ 92 ] Graber [ 93 ] Resilienceterm·def is associated with lowered psychological distress and health-promoting lifestyles. Black [ 93 ]; Campbell-Sills [ 94 ] Tan [ 95 ] Resilienceterm·def can potentially refer to pre-existing personality traits, the dynamic processterm of adaptation, a psychosocial outcome, or a mixture of all three. Luthar [ 15 ]; Bonanno [ 96 ]; Southwick [ 97 ] Tan [ 95 ] Specific qualities comprising resilienceterm·def have been identified including optimism, active coping skills and maintaining a social network. Iacoviell [ 98 ] Eshel [ 99 ] Resilienceterm·def has thus been defined as a stable trajectory of healthy functioning after a highly adverse event. Southwick [ 97 ] Eshel [ 99 ] Resilienceterm·def has thus been defined as the balance of individual strength (protective factors) and vulnerability (risk factors) following an adversityterm·dom or a traumatic event. Eshel [ 100 ]; Eshel [ 101 ] Eshel [ 99 ] Resilienceterm·def represents an integration of strength and vulnerability, and that understanding adaptation to adversities requires a concurrent examination of protective processes and risk factors. Masten [ 102 ] Stainton [ 37 ] Healthy, adaptive, or integrated positive functioning over the passage of time in the aftermath of adversityterm·dom. Southwick [ 97 ] Stainton [ 37 ] In the context of exposure to significant adversityterm·dom, resilienceterm·def is both the capacity of individuals to navigate their way to the psychological, social, cultural, and physical resources that sustain their wellbeing, and their capacity individually and collectively to negotiate for these resources to be provided and experienced in culturally meaningful ways. Ungar [ 103 ] Stainton [ 37 ] Resilienceterm·def is a dynamic capability which can allow people to thrive on challenges given appropriate social and personal contexts. Howe [ 104 ] Dulin [ 46 ] Resilienceterm·def as a mechanism for the protective effects of conscientiousness on health outcomes. O’Cleirigh [ 105 ] Dulin [ 46 ] Defined resilienceterm·def as “a combination of personality characteristics and successful coping that allows an individual to function adaptively in the face of or following adversityterm·dom.” Dale [ 106 ] Casale [ 107 ] Resilienceterm·def is broadly defined as a protective factor that makes people less vulnerable to future adverse life events. Ayed [ 108 ] Li [ 109 ] Resilient people have the ability to adjust and cope successfully in the face of adversityterm·dom, exhibiting a stable trajectory of healthy functioning across time and the capacity for positive emotions after having experienced stressful life events. Bonanno [ 110 ] Sharpley [ 69 ] Psychological resilienceterm·dom defined as a set of specific behavioral or attitudinal skills which help an individual cope effectively with stress and avoid becoming depressed. Von Ammon [ 111 ]; Bitsika [ 112 ]; Sharpley [ 113 ] De Terte, [ 114 ] Psychological resilienceterm·dom is as a combination of cognitions, behaviors, and environmental factors. These factors are optimism, adaptive coping, adaptive health practices, and social support from colleagues. De Terte, [ 31 ] 3.3. Capacity to Bounce Backterm·def Many authors define psychological resilienceterm·dom as the ability to recoverterm at the same time as the development of one’s resources and potential in the face of difficulties or stressful events. Understood in this way, the resilienceterm·def construct is configured as an attitude to adopt effective negotiation strategies that allow one to confront adversityterm·dom and to bounce back from the negative experience by promoting a process of personal growth (see Table 3 ). Table 3 Capacity to bounce backterm·def. Reference Articles Definition Proposed Citation Source Silverman [ 115 ] Resilienceterm·def is defined in the positive psychology literature as the human capacity to persist, bounce back, and flourish when faced with stressors. Bonanno [ 62 ] Chen [ 116 ] Resilienceterm·def is the capacity to adapt to and bounce back from adversityterm·dom and stressful events. Davidson et al. [ 117 ]; Prince-Embury [ 118 ] Brush [ 119 ] Resilienceterm·def as the ability to bounce back or cope successfully despite substantial adversityterm·dom. Earvolino-Ramirez [ 75 ] Netuveli [ 120 ] Resilienceterm·def is having good outcomes despite adversityterm·dom and risk and could be described in terms of preserving the same level of the outcome or rebounding back to that level after an initial setback. Using the latter definition, resilienceterm·def as “bouncing back”. Resilienceterm·def could involve either rebounding after adversityterm·dom. Garmezy, [ 20 ] Violanti [ 121 ] The term resilienceterm·def is often used to imply an ability to bounce back. Consequently, the definition adopted here embodies the notion of adaptive capacity. Klein [ 122 ] Earvolino-Ramirez [ 76 ] Resilienceterm·def, the ability to bounce back or cope successfully despite substantial adversityterm·dom. Rutter [ 8 ] Kalisch [ 123 ] The process of effectively negotiating, adapting to, or managing significant sources of stress or trauma. Assets and resources within the individual, their life, and environment facilitate this capacity for adaptation and “bouncing back” in the face of adversityterm·dom. Across the life course, the experience of resilienceterm·def will vary. Windle [ 124 ] Xing [ 125 ] Psychological resilienceterm·dom is defined as an individual’s ability to effectively adapt to and rebound from negative experience. Lazarus [ 126 ] Sharpley [ 69 ] Various aspects of this construct of psychological resilienceterm·dom have been identified, including the ability to rebound from disappointments, positive adjustment behaviors in adverse circumstances, or simply successful adaptation to challenging life stressors. Brooks [ 127 ]; Tedeschi [ 128 ]; Alvord [ 129 ] 3.4. Dynamic Processterm Evolving Over Time In the literature, it also emerges that coping with situations perceived as adverse or changeable occurs through a dynamic processterm of adaptation, influenced by personal characteristics, family, and social resources. Resilienceterm·def should therefore be understood not only as a personal attribute that can lead to success, but also as a dynamic interaction associated with adaptability and a positive history of functioning after adversities (see Table 4 ). Table 4 Dynamic processterm evolving over time. Reference Articles Definition Proposed Citation Source Dias [ 42 ] Resilienceterm·def may be defined as a dynamic processterm involving the interaction between both risk and protective factors, internal and external to the individual, that act to modify the effects of an adverse life event. Brandão [ 130 ]; Yunes [ 131 ] Dias [ 42 ] Resilienceterm·def should be understood not only as a personal attribute that may lead to success, but also as the dynamic interaction between biological and psychosocial processes. Dias [ 42 ] Caldeira [ 17 ] We propose a definition of resilienceterm·def which is the ability to recoverterm from perceived adverse or changing situations, through a dynamic processterm of adaptation, influenced by personal characteristics, family, and social resources, and manifested by positive coping, control, and integration. Caldeira [ 17 ] Kim-Cohen [ 86 ] Resilienceterm·def is theorized to result from a dynamic interplay among multiple factors that threaten adaptive functioning, as well as multilevel factors that protect against adversityterm·dom and promote positive adjustment. Cicchetti [ 87 ]; Luthar [ 88 ]; Masten [ 89 ]; Rutter [ 36 ] Stephens [ 23 ] Resilienceterm·def is “an ongoing process of struggling with hardship and not giving up”. Gillespie [ 132 ] Garcia-Dia [ 72 ] Resilienceterm·def can occur either as a process or as a motivational life force that can be developed in individuals. Haase [ 133 ] Davydov [ 19 ] Resilienceterm·def as a process or force that drives a person to grow through adversityterm·dom and disruption. Jacelon [ 134 ]; Richardson, [ 135 ]; Richardson [ 7 ] Patel [ 18 ] Resilienceterm·def is “a process or the attainment of positive outcomes at the individual, family, and community levels despite adversityterm·dom (e.g., natural disaster, terrorist attack). Lemyre [ 136 ] Kim-Cohen [ 86 ] Resilienceterm·def is conceptualized as dynamic with the understanding that adjustment can fluctuate over time in response to a stressor. Masten [ 102 ]; Masten Narayan [ 137 ] Davydov [ 19 ] Emotional resilienceterm·def has been used as the process linking resources (adaptive capacities) to outcomes (adaptation). Norris [ 138 ] Levine [ 139 ] Patterson’s perspective that family resilienceterm·def is an “ongoing, emergent process”. Resilienceterm·def was manifest in the process of moving from the position of “knowing” through listening to others to “knowing” developed in the context of listening to self. Patterson [ 140 ] Kim-Cohen [ 86 ] Resilienceterm·def is dynamic and interactive in that it is a process stimulated by the presence of adversityterm·dom rather than simply the balance of risk versus protective factors. Rutter [ 141 ] Brush [ 119 ] Resilienceterm·def is the process as “the capability to adapt better than expected in the face of significant adversityterm·dom or risk”. Tusaie [ 142 ] Brush [ 119 ] Resilienceterm·def implies a process of hurdling resistance and, in doing so, gaining strength against future stressors, challenges, crises, or trauma, much like a microbe develops resilienceterm·def over time to an antibiotic and ultimately adapts to and survives its environmental conditions. Adaptation and survival are thus consequences of resiliency while resiliency is an important individual characteristic in the process of overcoming. Hernandez [ 143 ] Lee [ 144 ] Resilienceterm·def as an active process that develops internal resources for coping with stress. Woodgate [ 145 ] Cuhadar [ 51 ] Resilienceterm·def is a dynamic processterm related to an individual’s capacity to cope with difficult or stressful experiences and the ability to psychologically overcome adversityterm·dom. Luthar [ 15 ]; Masten [ 146 ]; Basim [ 55 ]; Wright [ 56 ]; Sharpley [ 69 ] Karoly [ 60 ] Resilienceterm·def is considered both functional and dynamic, in that it implies the effective performance of life tasks by virtue of a complex interaction between varied risk and protective factors. Luthar [ 14 ]; Olson [ 147 ] Takahashi [ 148 ] Resilienceterm·def is defined as “a dynamic processterm encompassing positive adaptation within the context of significant adversityterm·dom.

De Alfieri [ 149 ] Paletti [ 150 ] Resilienceterm·def as ‘‘a set of qualities that foster a process of successful adaptation and transformation’’ in the face of adversityterm·dom. Resilienceterm·def may be seen as prerequisite to recovery; by engaging in resilient behaviors, bereaved individuals may work toward the self-transformation inherent in successful adaptation to loss. Benard [ 151 ] Earvolino-Ramirez [ 75 ] Resilienceterm·def is a dynamic developmental process. Luthar [ 152 ] Pangallo [ 153 ] Resilienceterm·def is best defined as a process characterized by a complex interaction of internal and external resources moderated by developmental influences. Masten [ 154 ]; Rutter [ 155 ]; Werner [ 156 ]; Windle [ 124 ] Ungar [ 73 ] I defined resilienceterm·def as the capacity of both individuals and their environments to interact in ways that optimize developmental processes. Specifically, research shows that in situations of adversityterm·dom, resilienceterm·def is observed when individuals engage in behaviors that help them to navigate their way to the resources they need to flourish. Ungar [ 157 ] Dias [ 42 ] Resilienceterm·def is a process associated with adaptive capacities and a positive history of functioning and adaptation after adversities. This dynamic processterm involves the interaction between biological and psychosocial factors, which makes its investigation more complex. Dias [ 42 ] Tan [ 95 ] Resilienceterm·def refers to a dynamic processterm of positive adaptation within the context of adversityterm·dom. Luthar [ 15 ] Eshel [ 99 ] Resilienceterm·def is a dynamic state of mind that may change due to changing circumstances which will modify the existing balance of individual protective factors and risk factors. Ungar [ 103 ] Stainton [ 37 ] “Resilienceterm·def is the process of effectively negotiating, adapting to, or managing significant sources of stress or trauma.” Windle [ 124 ] Graber [ 92 ] Psychological resilienceterm·dom is a psychosocial developmental process through which people exposed to sustained adversityterm·dom experience positive psychological adaptation. Luthar [ 14 ]; Rutter, [ 74 ] Dulin [ 46 ] Resilienceterm·def resources are also viewed here as processes that buffer against and are potentially more malleable to intervention than some of the aforementioned adversities at the individual, interpersonal, and neighborhood levels. Dale [ 158 ]; De Santis [ 159 ]; Kent [ 160 ]; Steinhardt [ 161 ] 3.5. Positive Adaptation to Life Conditions Resilienceterm·def is also referred to as the ability to deal with stress conditions. The processes of psychological resilienceterm·dom have to do with the cognitive evaluation carried out by the subject, which regulates the possibility of finding effective forms of adaptation. The thought processes, the emotional and behavioral responses through which resilient subjects build their personal vision of reality, give rise to decisions and behaviors that allow them to adapt to stressful or adverse conditions (see Table 5 ). Table 5 Positive adaptation to life conditions.

Gibson [ 187 ] Horn [ 188 ] Resilienceterm·def is broadly defined as the dynamic ability to adapt successfully in the face of adversityterm·dom, trauma, or significant threat. Resilienceterm·def is complex and might be best conceptualized on a continuum, with the potential for it to change across an individual’s lifespan.

Fletcher [ 1 ]; Earnshaw [ 193 ]; Unger [ 194 ] 4. Discussion Our literature reviewterm·mth shows that psychological resilienceterm·dom is described in different ways. This discrepancy in terminology can hinder a shared definition of the construct, which limits comparisons among the research results and makes objective measurement difficult. Based on our analysis of the literature, we identified five macro-categories which, on the one hand, summarize the recurring elements in the definition of resilienceterm·def across the works examined; on the other, they highlight the multidimensionality of the construct. Over the years, several authors described resilienceterm·def as ‘ability to recoverterm’ . However, this expression has been understood in various ways. Specifically, some authors define resilienceterm·def in terms of ability to recoverterm from trauma, stress, or deprivation; others understand it as the ability to remain well despite the difficulties or to recover completely and quickly. The recovery is also intended as a return to a state of balance, as a posttraumatic growth ability, or as learning of useful skills for overcoming future risks. Additional authors describe resilienceterm·def in terms of recovery by using protective barriers to stress. In summary, the ability of recovery represents the tendency of the individual to maintain their own internal balance despite the experience of traumatic events or stressful conditions. Moreover, the capacity for resilienceterm·def indicates the ability to deal positively with traumatic events and to reorganize in the face of difficulties. We found that resilienceterm·def was also described in literature as a ‘ Type of functioning that characterizes the individual’. The resilienceterm·def functioning was intended as an ability both to maintain good levels of psychological and physical health and to return to a state of balance despite adversities. In this context, a reference to resilient qualities emerges in terms of individual features or personality traits such as robustness and resourcefulness, with some authors affirming that these qualities are innate and influenced by the external environmental only in a limited way. The functional adaptation to adverse conditions can be facilitated or hindered by the interaction between internal protective and risk factors. In this regard, literature has recently turned towards a concept of resilienceterm·def understood as a complex phenomenon in which several factors come into play, including innate personality traits, personal purposes, and the external and psychosocial context. By exploring the protective factors that enable the implementation of resilient behaviors, we can identify the following categories: Cognitive flexibility, positive affect and optimism, humor, acceptance, active coping, religion or spirituality, altruism, social support, role models, exercise, capacity to recover from negative events, and stress inoculation. In summary, what determines resilienceterm·def are the personal qualities identified as protective factors despite stressful or traumatic events. A third group of definitions, albeit small, refers to resilienceterm·def as ‘ capacity to bounce backterm·def’ . Although this description of resilienceterm·def seems to be like that of the ability of adaptation, we believe that it deserves to be included in another category as it emphasizes a particular response mode, namely referring to some specific characteristics. Thus, resilienceterm·def as capacity to bounce backterm·def outlines the ability to persist and grow when faced with stressors, to cope despite adversityterm·dom, and to bounce from negative experience. Resilienceterm·def refers to having good outcomes despite adversityterm·dom and risk, and could be described in terms of preserving the same level of outcome or rebounding back to that level after an initial setback. More specifically, resilienceterm·def as ‘bouncing back’ could involve either rebounding after adversityterm·dom or affectively adapting to adversityterm·dom. The resilienceterm·def construct over the years has also been identified as a ‘ dynamic processterm evolving over time ’. Specifically, dynamic processterm here means firstly the interaction between internal and external protective factors that act to modify the personal effects of an adverse event. Secondly, it refers to the interaction between personal characteristics, biological processes, and family and social resources that can promote or hinder resilient processes. Within this macro-category, it is possible to identify several shades of meaning of the term resilienceterm·def. Some authors define it as a vital motivational force of the individual that foresees an attitude of continuous struggle and an inclination not to surrender before difficulties, or as a force that can fluctuate over time and push the person to grow through the adversities or interruptions of their life trajectory. Others emphasize the ability to promote developmental processes and identify resilienceterm·def with a dynamic mental state that can adapt to changing circumstances. Resilienceterm·def is also defined as a process through which individuals survive or even grow in the face of adversityterm·dom. It involves both a set of qualities or internal traits, such hardiness or high self-efficacy, and external factors, such as social support, that promote coping skills. Given the great attention paid by the literature to the meaning of resilienceterm·def as a capacity for adaptation, we decided to include this definition in a specific category, namely ‘ positive adaptation to life condition’. In describing resilienceterm·def in these terms, authors emphasize different aspects of the phenomenon. Some describe it as the ability to promote positive adaptation despite exposure to adverse, stressful, or traumatic conditions. Others define it as an adaptive attitude and behavior that allows one to remain psychologically healthy, or even to thrive until a post-traumatic growth after being exposed to stressful events. Thus conceived, resilienceterm·def implies that emotional resources are used to adapt to adversityterm·dom; therefore, it can also be described as the process that links resources (adaptive capacities) to results (adaptation). Other authors focus attention on the duration of the phenomenon. In particular, some describe resilienceterm·def as a temporary phenomenon, subject to fluctuations based on life circumstances and the stage of development; for others it represents a stable trajectory of operation over time. The analysis of the literature shows that the term resilienceterm·def does not have a single meaning and takes on different nuances depending on the perspective from which it is analyzed. In the field of resilienceterm·def studies, there is a heated debate among scholars, in particular between those who consider resilienceterm·def as a trait of personality that is fixed and stable over time and therefore measurable (‘type of functioning that characterizes the individual’) and those who do not consider it a personality trait but rather as ‘dynamic processterm evolving over time’, which refers to the interaction between protective factors and risk factors. Specifically, the effects of protective factors such as ‘type of functioning’ are detectable only in the presence of the stressful events, and their role is to modify the response despite adversityterm·dom. The ‘dynamic processterm’ is instead described as the interaction of a constellation of variables that allow the reduction of the impact with the risk conditions and thus effectively dealing with the adverse condition. In the ‘recovery category’, it is also possible to identify the attitude toward a gradual return to an initial state—staying well and maintaining an effective functioning—despite the destabilization caused by an adverse event that has a significant impact on the person. Therefore, it is understood as a return to an initial state of balance. The ‘capacity to bounce backterm·def’ instead emphasizes the possibility of a personal growth despite difficulties, changes, or traumatic events rather than a return to an initial state of mind. Literally, ‘bounce back’ means rebound and change of direction. It refers to the tendency to be persevering and not to give up, assuming an attitude of openness to change. We consider the fifth category, ‘positive adaptation to life conditions’ , as transversal to the other four that we have identified because the concept of effective adaptation to life events is implicit in each of them. Nevertheless, we have established it as a different category from the others since many definitions in the literature focus on the concept of positive adaptation to define resilienceterm·def. As can be seen by comparing the tables, the category that identifies resilienceterm·def as ‘positive adaptation’ includes many definitions. Summarizing all the categories, the processes of psychological resilienceterm·dom make it possible to face events by maintaining and enhancing one’s resources to the point of producing personal strengthening and a positive reorganization of one’s biographical history. Therefore, the use of resilient attitudes makes it possible to construct and rebuild one’s life path, to re-establish a new balance by producing change in oneself and reacting positively in the face of difficulties, transforming them into opportunities for growth. From the study that we conducted, it was interesting to observe the multidimensionality of the resilienceterm·def construct, which has been described in the literature from different points of view, in some cases with common characteristics. The revision of the definitions of resilienceterm·def has allowed us to better clarify this term and to propose a broader definition characterized by the elements that we have supposed as being more indicative of the resilient attitude. According to the results of our study, resilienceterm·def should be considered as a ‘competence’ present in each individual or organization, thanks to which it is possible not to succumb to adverse events, but to react and to reach, or to return, to a state of equilibrium. The importance of the work we carried out thus lies in having observed that resilienceterm·def resources are considered as ‘skills’ that should be present and functional both on an individual level, for example in professional practice or in social relations, and in organizations. Moreover, being a dynamic processterm, resilienceterm·def can be implemented in order to promote a continuous growth of the person and the environment. Getting to know more about the resilienceterm·def construct also makes it feasible to structure training pathways focused on resilient human qualities as tools aimed at fostering an attitude of openness to change. Regarding the clinical setting, the analysis of the resilienceterm·def construct we carried out through the reviewterm·mth is also a useful starting point with reference to the identification of models of psychological intervention aimed at enhancing individual resources and abilities in order to support the attitude of facing adverse situations while maintaining an adaptive functioning. However, it is necessary to underline that this study has some limitations that we hope to fill in a future research. More specifically, a limitation refers to the methodology of selection of the articles to be analyzed. The use of the keyword ‘definition’ inserted in both of the accessed search engines has excluded some studies which could be useful to further widen the analysis of the resilienceterm·def construct. Moreover, extending the study to other databases, as well as considering scientific articles written before 2002, would allow us to obtain a greater number of works and to identify probable further definitions of the term resilienceterm·def. Finally, the reviewterm·mth focused on resilienceterm·def as a psychological construct, thereby excluding the possibility of accounting for nuances of the term other than the personal one that was investigated. 5. Conclusions The analysis of the literature has made it possible to identify multiple definitions of psychological resilienceterm·dom. As proposed in our discussion of the results, the concept of resilienceterm·def can be defined by focusing attention on different contents that describe it in a different way. Based on the previously discussed results, we propose our own definition of psychological resilienceterm·dom that takes into account the transversal elements found in the definitions we analyzed in order to proceed towards ‘a conceptual unification’ of the term. According to the literature search that we carried out, it can be affirmed that psychological resilienceterm·dom is the ability to adapt positively to life conditions . It is a dynamic processterm evolving over time that implies a type of adaptive functioning that specifically allows us to face difficulties by recovering an initial balance or bouncing back as an opportunity for growth. We believe that resilienceterm·def is the ability to maintain one’s orientation towards existential purposesterm despite enduring adversities and stressful events. It foresees an attitude of persistence before the obstacle and openness to change. This concept can be understood as the ability to deal with the difficulties experienced in the different areas of one’s life with perseverance, maintaining a good awareness of oneself and one’s own internal and parallel coherence by activating a personal growth project. This persevering attitude makes it possible to activate one’s own resources to recover after having experienced adverse conditions, re-establishing the state of personal balance. In our definition, the term ‘purpose’ refers to long-term objectives and the overall objective regarding existence in its complexity. The latter varies from individual to individual according to their life commitments (vocational, affective, social, professional, etc.). Broadly speaking, through the acts of resilienceterm·def related to partial ends, the individual becomes more and more persistent in the orientation towards their personal fulfillment. Our attempt at conceptual clarification of the term resilienceterm·def, in also highlighting that specific skills and individual characteristics are necessary for a good maintaining of one’s own orientation towards existential purposesterm, will be a useful starting point for further research aimed at deeply exploring resilienceterm·def resources and at identifying effective training strategies to support them.
