Socially-supported sleepterm·dom in older adultsterm·key aged 50 and older: a concept analysisterm·key.
Abstract The population of older adultsterm·key is growing disproportionately, constituting 13% of the global population in 2022, and is expected to double by 2050. One of public health’s priorities is healthy agingterm·key, the maintenance of functional abilityterm·dom aligned with well-being. As many as 50% of older adultsterm·key report poor sleep qualityterm·dom, leading to an increased risk of morbidity and mortality. The quality and quantity of social relationships may broadly benefit sleep in older adultsterm·key. However, the concept of socially-supported sleepterm·dom is underdeveloped as a basis for intervention.
Existing literature was searched without time restriction in PubMed, CINAHL, PsycINFO, and Scopus ending in August 2022. Thematic analysis was used to determine the defining attributes, antecedents, and consequences of socially-supported sleepterm·dom guided by Rodgers’ evolutionary concept analysisterm·key.
Twenty-nine articles written in English, peer-reviewed, and examined social supportterm·dom and sleep in participants aged ≥50 were included. The defining attributes reflect dimensions of sleep qualityterm·dom. The antecedents are safe and secure, belonging and connection, and warmth and comfort. The consequences of socially-supported sleepterm·dom include improved regulatory capabilities, physical and emotional well-being, and quality of life.
Socially-supported sleepterm·dom has the potential to inform interventions that promote sleep in older adultsterm·key. Ongoing research is needed to address the antecedents and mechanisms through which socially-supported sleepterm·dom may promote sleep qualityterm·dom for healthy agingterm·key.
Keywords: social connectionterm·dom, healthy agingterm·key, sleep, Rodgers, concept analysisterm·key Introduction The population of older adultsterm·key worldwide is growing disproportionately and is expected to nearly double from 12 to 22% by 2050 ( 1 ). One of public health’s priorities is healthy agingterm·key, the maintenance of functional abilityterm·dom aligned with well-being ( 2 ). Functional abilityterm·dom refers to what is valued by older people and the extent to which they are able to function aligned with values; to pursue valued objectives with dignity. For example, older adultsterm·key value meeting their basic needs, to learn and make decisions, be mobile, make and maintain meaningful connections with others, and contribute to society ( 3 ). The interaction between an individual’s environment and intrinsic capacityterm·dom, which encompasses emotional, physiological, and behavioral regulatory capabilities, determines their functional abilityterm·dom ( 4 ).
Sleep is essential to intrinsic capacityterm·dom for healthy agingterm·key, as it provides a restorative process central to maintaining regulatory capabilities and well-being ( 5 , 6 ). While sleep disturbances are greater in pathological aging, healthy older adultsterm·key also experience characteristic changes in the structure and quality of sleep ( 7 ). As many as 50% of older adultsterm·key report impaired quality and quantity of sleep ( 8 ), characterized as lowered sleep efficiency, diminished sleep qualityterm·dom and amount of total sleep time, and increased sleep fragmentation and diurnal sleepiness ( 7 ).
Sleep is essential for health; insufficient sleep and untreated sleep disorders are harmful for health and well-being ( 9 ). Increasing the proportion of adults who get sufficient sleep is a priority of Healthy People 2030, with the goal of improved health, well-being, and quality of life ( 10 ). Impaired quality and quantity of sleep is associated with elevated morbidity and mortality ( 11 ). Sleep disturbances (i.e., poor sleep efficiency, diminished total sleep time, and increased sleep latency) are associated with increased risks of mortality even after controlling for covariates ( 12 , 13 ). More than 80% of older adultsterm·key reporting sleep disturbance have one or more major mental or physical disorder ( 14 ). For example, impaired sleep qualityterm·dom is associated with increased systemic inflammation ( 15 ), cardiovascular diseases ( 16 , 17 ), depression and anxiety ( 18 ), cognitive impairment ( 7 , 19–21 ), fall risk ( 22 ), and decline in quality of life ( 23 ). Lastly, the economic costs associated with sleep disturbances and/or sleep disorders are substantial. One study indicated that the overall costs of sleep disorders in the year of 2019–2020 was $35.4 billion ( 24 ), and the data may represent similar trends in other developed countries. Thus, there is an urgent need for attention to sleep health in research and clinical practice, as well as innovative approaches to mitigate sleep disturbance in older adultsterm·key aligned with healthy agingterm·key.
A body of research provides support for the role of social relationships in healthy agingterm·key ( 25–27 ). Social supportterm·dom has been broadly understood as an individual’s experience of being loved, cared for, valued, and respected within a social network of reciprocal commitments ( 28 ). This perspective acknowledges the older person in purposeful interaction with their environment, both providing and receiving predictable connection, care, and comfort ( 29 ). Holt-Lunstad ( 30 ) clarifies social supportterm·dom as a functional indicator of social connectionterm·dom, marking the actual or perceived availability of tangible support, informational support, emotional support, and belonging support.
A recent review of 23 meta-analyses examining social supportterm·dom and health outcomes found a robust effect of social supportterm·dom on health and longevity, with the strength of association equivalent to that of risk factors such as smoking or obesity ( 29 ). In the context of healthy agingterm·key, access to social supportterm·dom is associated with greater engagement in preventive health behaviors ( 31 ), greater resilience ( 32 ), lower inflammation ( 26 ), and less cognitive decline ( 33 ). Research examining sleep and social relationships provides support for associations between the quality and presence of social relationships and sleep across the lifespan. According to a systematic review, high quality, mutually supportive relationships are associated with better quality sleep both in the moment and over time, while low quality, distressing relationships are associated with poorer sleep ( 34 ). Greater social supportterm·dom is significantly related to improved sleep outcomes across types of social supportterm·dom ( 35 ), decreased effects of rumination on sleep qualityterm·dom ( 36 ), and lowered risk of poor sleep qualityterm·dom and short sleep duration ( 37 ). In contrast, chronic exposure to negative support and decline in social relationship quality is related to poorer sleep qualityterm·dom ( 38 ).
There has been increasing research regarding the role of social supportterm·dom in promoting sleep qualityterm·dom in adults ( 34 , 35 , 39 , 40 ), and the development of interventions leveraging social supportterm·dom to promote healthy agingterm·key ( 27 , 40 ). However, there remains a lack of conceptual clarity or shared understanding of socially-supported sleepterm·dom in the context of healthy agingterm·key. Given the aging population, clarification and development of the concept of socially-supported sleepterm·dom in older adultsterm·key will advance understanding of a potentially modifiable factor which may be targeted to facilitate healthy agingterm·key.
The aim of this manuscript is to present a concept analysisterm·key of socially-supported sleepterm·dom in older adultsterm·key in the context of healthy agingterm·key using an evolutionary perspective ( 41 ). The objective of the concept analysisterm·key was to introduce a definition that could be of use in research and clinical practice. Concept analysisterm·key is a systematic process used to inform a precise definition and foster a shared understanding of a concept of interest ( 41 ). Concept analysisterm·key of socially-supported sleepterm·dom in older adultsterm·key provides an important preliminary step in programmatic research, addressing conceptual clarity of socially-supported sleepterm·dom, an important and developing concept. The evolutionary method was chosen as its analytic philosophical base is grounded in dynamism; concepts are not viewed as static; rather, they are viewed as abstractions that change with time and varied situations ( 42 , 43 ). This concept analysisterm·key will: (a) describe the evolution of socially-supported sleepterm·dom, (b) analyze the defining attributes, antecedents, and consequences, (c) define the concept of socially-supported sleepterm·dom, and (d) characterize opportunities for development of the concept, providing a step toward evaluating relevance in older adultsterm·key and advancing meaningful public health research in this area.
Methods and materials Rodgers’ evolutionary method Concept analysisterm·key provides an approach to analyze, define, develop, and evaluate concepts of use to public health research and practice ( 44 , 45 ). Rodgers’ evolutionary method provides a reliable and relevant approach to developing public health knowledge by applying inductive analysis of relevant literature ( 44 ). An evolutionary approach to concept analysisterm·key includes core processes, which are nonlinear and iterative in nature ( 46 ): (a) choice of concept for analysis and context, and collection of data for analysis, (b) core analysis in which antecedents, attributes, consequences, and definition are identified, and (c) opportunities for development of the concept, its meaning, and its potential to advance public health knowledge ( 45 , 47 ). Socially-supported sleepterm·dom was chosen for analysis due to its significance in serving a purposeful goal in the context of healthy agingterm·key. Aligned with the evolutionary approach, data characterizing the attributes, references, antecedents, consequences, and definition of socially-supported sleepterm·dom were derived ( 43 ). The attributes of a concept, or cluster of characteristics, make it possible to identify phenomena that are categorized under the concept. Antecedents are those phenomena leading up to the concept and can also be described as preceding events, conditions, or causes. The consequences refer to factors that are results of the concept. Opportunities for development of socially-supported sleepterm·dom provide the basis for future research.
Search strategy An integrative review of the relevant literature was conducted to inform the concept analysisterm·key in the context of healthy agingterm·key. The English-language literature was searched without time restriction, using combinations of “social supportterm·dom” AND “sleep qualityterm·dom” OR “sleep duration,” OR “sleep disturbance,” AND “aged” OR “older adultterm·key” in PubMed. Specifically, MeSH terms “social supportterm·dom,” “aged,” and “sleep duration” were used in PubMed. Similar keywords and combinations were then used to search for articles in CINAHL, PsycINFO, and Scopus ending on August 23rd, 2022. All publication types were accepted, except for abstracts, dissertations, and protocols. Articles were excluded for the following reasons: (a) the population of the study not 50 + older adultsterm·key; (b) the article being duplicative of another article; (c) socially-supported sleepterm·dom not the primary focus of the article; (d) the article not being peer-reviewed.
Data analysis A historical timeline of the concept of socially-supported sleepterm·dom was developed to address the evolution of the concept. Data from the articles were abstracted and organized using thematic analysis to determine the antecedents, defining attributes, and consequences of socially-supported sleepterm·dom, and inform the concept definition. During first level analysis, investigators independently reviewed the articles to better understand the data in context and identify patterns repeated throughout the articles ( 44 ). During second level analysis, the data were coded across studies, using constant comparison to group conceptually similar codes and allow main themes to emerge from the data ( 44 ). Through analysis, investigators achieved consensus regarding antecedents, attributes, and consequences. Further, the analysis process informed opportunities for development of socially-supported sleepterm·dom, contributing to the clarification of a concept significant in the context of healthy agingterm·key.
Results Study characteristics and evolution of socially-supported sleepterm·dom A total of 345 articles were generated, 42 relevant articles received full-text screening, and 23 full-text articles meeting the criteria were selected. A manual search was conducted, resulting in six additional articles. Thus, a total of 29 articles examining social supportterm·dom and sleep in participants aged ≥50 were included ( Figure 1 ). The studies were published between 1996 and 2022. Most of the studies used cross-sectional design; a few also used longitudinal design. Sample size range from 74 to 8,456. Participant characteristics are shown in Table 1 .

Participant characteristics in each study.
A review of the evolution of socially-supported sleepterm·dom is necessary to understand the conceptual basis and temporal variations of the concept ( 43 ). The concept of social supportterm·dom in the context of health and illness has been examined across a myriad of disciplines ( 29 , 48 , 49 ). Among the earliest contribution to this literature was ( 50 ), finding that a lack of social connectionterm·dom was related to higher suicide rates. The literature on the role of social supportterm·dom in physical and mental health was advanced by theories of human needs and motivations ( 51 ) and attachment theory ( 52 ). From the perspective of attachment theory ( 52 ), attachment figures provide emotional security through contact and reassurance, functioning as a safety signal. Further conceptual development of social supportterm·dom in the context of health and mortality addressed social supportterm·dom as a protective factor that buffers the individual from the physiological and psychological consequences of exposure to life stress ( 28 , 53 ). Berkman and Syme were among the first to examine all-cause mortality and social relationships in a longitudinal study ( 54 ). Findings provided empirical support for the relationship between social and community ties and mortality independent of initial health status and lifestyle risk factors. Following a period of exponential growth in research characterizing social supportterm·dom and health, conceptual frameworks were developed to more clearly define and operationalize the structural, functional, and quality dimensions of social supportterm·dom ( 29 ). Holt-Lunstad ( 30 ) called for a multifactorial conceptualization, with social connectionterm·dom providing an umbrella term that encompasses the structure, function, and quality of social relationships. Structural dimensions refer to the characteristics of the social network around the individual, such as number of relationships and social integration. Functional dimensions refer to the characteristics of the support provided by social networks, such as perceived and received support. Quality dimensions acknowledge positive and negative affective qualities of social connectionterm·dom, such as satisfaction ( 25 , 30 , 55 ). A recent meta-analysis examining the relationship between social supportterm·dom and sleep found that perceived social supportterm·dom was significantly correlated with favorable sleep outcomes across age groups ( 35 ). However, there is limited conceptual understanding of socially-supported sleepterm·dom, especially in older adultsterm·key.
Concept attributes Concept attributes are critical characteristics of a concept that elucidate the meaning of the concept and make it possible to identify situations that are categorized under the concept ( 41 , 43 ). The defining attributes of socially-supported sleepterm·dom derived from the studies reviewed include subjective and objective attributes, including sleep qualityterm·dom, sleep duration, sleep onset latency, wake after sleep onset, sleep disturbance, and daytime dysfunction ( Table 2 ).
Literature support for antecedents, attributes, and consequences of socially-supported sleepterm·dom in older adultsterm·key aged 50 and older.
The majority of the studies reviewed measured subjective and objective attributes using self-report Likert scales, including study developed measures ( 37 , 56–64 ), Pittsburgh Sleep Quality Indexterm·mth (PSQIterm·mth) ( 38 , 65–77 ), one item extracted from the Center for Epidemiological Studies Depression (CES-D) scale ( 78 ), Patient-Reported Outcomes Information System (PROMIS) Sleep Disturbance Measure-Short Form version 2.1. ( 36 ), Nottingham Health Profile ( 79 ), Athens Insomnia Scale (AIS) ( 80 ), Insomnia Severity Index ( 81 ), and the Pittsburgh Sleep Diary (PghSD) ( 72 ). Several studies used objective sleep measure, including wrist actigraphy ( 72 ) and NightCap Sleep recordings ( 66 ).
Sleep qualityterm·dom Among the studies reviewed, sleep qualityterm·dom was operationalized in terms of sleep problems and/or disorders as well as the level of distress experienced by sleep problems and/or disorders. Significant associations were reported between social supportterm·dom and sleep qualityterm·dom, such that older adultsterm·key who report higher levels of social supportterm·dom experience less sleep problems and/or disorders ( 36–38 , 56 , 59 , 64 , 66–70 , 73–77 , 79–82 ). Research examining the links between positive and negative network ties and sleep qualityterm·dom found that supportive ties were positively related to sleep qualityterm·dom, whereas aversive ties predicted worse sleep qualityterm·dom ( 68 ). Similarly, a persistent break with a close tie was a predictor for trouble falling asleep and staying asleep among older adultsterm·key ( 58 ). Child and colleagues ( 58 ) examined the effect of change in personal network support on sleep qualityterm·dom at three time-points over the course of 3 years. Change in network support was associated with difficulty staying asleep, but not falling asleep. Longitudinal findings supported that baseline positive support (age 53) and increase in positive support from the closest person over the span of 15 years ( 53–68 ) were associated with better sleep qualityterm·dom at age 68, while sleep qualityterm·dom was poorer for those who experienced declining positive support or increasing negative support ( 38 ). Further, participants who nominated their spouses or partners as closest person had better sleep qualityterm·dom compared to those who nominated another person ( 38 ). Participants who kept their closest person as their spouse or partner at both the age 53 and 68 had better sleep qualityterm·dom compared to those who had spouse/partners at the age of 53 but not at 68 ( 38 ). Older adultsterm·key with support from friends were less likely to report inadequate sleep. In a natural experiment examining the unique impact of disaster damage on sleep problems, Li and colleagues ( 70 ) reported both pre-disaster instrumental and emotional social supportterm·dom protected older adultsterm·key aged 60 and above from poor sleep qualityterm·dom.
Sleep duration Among community-dwelling older adultsterm·key, lower perceived support from friends was associated with poor sleep duration ( 65 ), while perceived instrumental support was associated with a decreased risk of short sleep duration (< 5 h/night) ( 70 ). Similarly, perception of intermediate and high social supportterm·dom from partners and high social supportterm·dom from family members and friends was found to be protective from short sleep duration ( ≤ 6 h/night) after covariate adjustments ( 37 ). Compared to older adultsterm·key with high perceived network support, those with lower support experienced a reduction in sleep duration over time. Those with worse network support were at high risk of sleeping < 6 h/night ( 60 ). Yang and colleagues ( 63 ) found that generalized trust had a protective effect on insufficient sleep; older adultsterm·key feeling people around them were untrustworthy showed greater odds of short sleep duration (< 7 h/night). In addition, reduced risk of long sleep duration (> 9 h/night) was found in older adultsterm·key with high level of informal/formal social participation ( 63 ). Specifically, female older adultsterm·key with no emotional support or social participation were vulnerable to higher risk of short and long sleep duration ( 63 ).
Sleep onset latency Increased perceived social supportterm·dom quality was significantly associated with diminished sleep latency in older adultsterm·key in the Frailty in Brazilian older adultterm·key Individuals (the FIBRA Study) ( 79 ). Positive support received from the closest person at the age of 68 protected participants with longer sleep onset latency by 7% ( 38 ). A higher level of social supportterm·dom was associated with shorter diary-assessed sleep latencies among older adultsterm·key with insomnia compared to healthy controls ( 72 ).
Sleep disturbance The relationship between interpersonal relationships outside of the household and sleep disturbance as restless sleep was examined at three time-points over the course of 6 years among older adultsterm·key enrolled in the Panel on Health and Aging of Singaporean older adultterm·key (PHASE) ( 78 ). Findings confirmed reciprocal associations between weak social networks and restless sleep; associations were mediated by depressed mood ( 78 ). Worse baseline social supportterm·dom was associated with increased risk of early awakening and difficulty getting back to sleep in a cohort of 1,444 Spanish participants followed between 2012 and 2015 ( 60 ). The relationship between perceived social supportterm·dom measured as affection, emotional/informational support, tangible support, and positive interaction and sleep disturbance was examined in 480 men and women with knee pain enrolled in the Observational Arthritis Study in Seniors (OASIS) ( 62 ). It was hypothesized that higher perceived social supportterm·dom was associated with lower sleep disturbance; however, the association did not survive multivariate analysis when factoring other predictors of sleep disturbance ( 62 ). In a cohort of community-dwelling Japanese participants, those with strong perceived support from their spouse and family had a significantly lower adjusted odds ratio of sleep disturbance ( 69 ). In community-dwelling older adultsterm·key with dementia, greater social supportterm·dom and having a partner were significantly associated with decreased sleep disturbance ( 59 ).
Wake after sleep onset & daytime dysfunction Higher levels of perceived social supportterm·dom, measured as the availability of emotional, belonging, self-esteem, and tangible support were associated with shorter actigraphy-measured wake after sleep onset in both older adultsterm·key diagnosed with insomnia and healthy controls ( 72 ). Among older benzodiazepine users, Proulx-Tremblay and colleagues ( 71 ) found a significant relationship between diurnal dysfunction related to quality of sleep and overall satisfaction with social supportterm·dom; the less satisfaction with social supportterm·dom received the greater the reported diurnal dysfunction (daytime sleepiness) related to poor sleep qualityterm·dom.
Antecedents Antecedents are precursors, events, or conditions that take place prior to socially-supported sleepterm·dom and provide the contextual basis for the concept ( 43 ). Safe and secure, belonging and connection, and warmth and comfort were identified as the antecedents to socially-supported sleepterm·dom in the concept analysisterm·key ( Table 2 ).
Safe and secure Supportive, close relationships are linked to sleep qualityterm·dom as such relationships provide a safe context in which sleeping individuals are protected by close others. Close relationships may foster sleep qualityterm·dom by providing a sense of safety, security, and protection ( 37 , 38 , 56 , 59 , 63 , 65 , 79 , 80 ). Older adultsterm·key with low levels of trust in others were less likely to experience a sense of safety, leaving them vulnerable to poor quality sleep and short sleep duration ( 63 ). Bazargan ( 56 ) found that older adultsterm·key with lower perceived emotional support as empathy, care, and trust, reported a higher level of sleeping problems (i.e., initiating and maintaining sleep). Similarly, lacking a trustworthy relationship with children, neighbors or friends was significantly associated with a higher likelihood of severe insomnia ( 80 ). da Costa and colleges ( 79 ) reported that having the perception that there was someone to protect you from social isolation and loneliness may be translated into a situation that provides comfort to older adultsterm·key. In the context of sleeping, social supportterm·dom from the closest person acted upon the emotional regulation of the participants, down-regulated “watchfulness” and thus improved sleep qualityterm·dom ( 38 ).
Belonging and connection Social supportterm·dom may influence sleep qualityterm·dom by providing a sense of connection and belonging ( 37 , 58 , 63 , 77–80 ). Social supportterm·dom which provided a sense of belonging and connection was shown to have a protective effect on long sleep duration in rural older adultsterm·key ( 63 ). Network insufficiency, particularly the desire for practical support, is predictive of both higher odds of troubled sleep and greater severity of troubled sleep ( 58 ). Older adultsterm·key who felt that they would not be provided with spiritual or financial support during difficulty reported more severe insomnia ( 80 ). Social supportterm·dom can improve sleep qualityterm·dom through enabling a feeling of belonging and connection and protect older adultsterm·key from negative emotions and social isolation ( 77 , 79 ). Similarly, intermediate, and high-level social supportterm·dom from spouse/partner and family members provided a sense of belonging and connection that protected against social isolation and buffered the effect of psychological stress on sleep, leading to lower risks of sleep complaints and short sleep duration ( 37 ).
Warmth and comfort Among the studies reviewed, warmth refers to emotional warmth in comforting, trusting, and satisfying relationships with those who provide support, particularly the significant other or the closest individual ( 36–38 , 58 , 69 ). Those with weak social supportterm·dom from spouses or family members were at a higher risk of sleep disturbances compared with those with strong social supportterm·dom ( 69 ). Having intermediate and high-level support from the spouse/partner or family provided the opportunity to detach from stressful situations, protecting older adultsterm·key from sleep complaints and short sleep duration ( 37 ). Being partnered or married was protective against the deleterious effects of stress on the severity of troubled sleep and prevented worse sleep qualityterm·dom in the presence of a negative event ( 58 ). In community-dwelling, partnered older adultsterm·key, enduring, warm, and comforting support from spouses or partners significantly buffered the effects of rumination on sleep qualityterm·dom ( 36 ). On the contrary, support from family and/or friends did not significantly protect older adultsterm·key from poor sleep qualityterm·dom due to rumination ( 36 ).
Consequences Consequences are the results or the outcomes of socially-supported sleepterm·dom. Among the studies reviewed, socially-supported sleepterm·dom is proposed as a protective resource for healthy agingterm·key, with proposed consequences of improved regulatory capabilities, physical and emotional well-being, and quality of life ( Table 2 ).
Regulatory capabilities Socially-supported sleepterm·dom may contribute to regulatory capabilities in older adultsterm·key. Among the studies reviewed, being safe and secure in the context of sleep was linked to down-regulation of vigilance and improved physiological and emotion regulation ( 38 , 59 , 65 ). Higher levels of support may reduce the negative physical and emotional consequences associated with social anxiety and stress by attenuating the effects of stressors ( 37 , 58 , 65 , 69 , 79 , 80 ). The perception of the spouse as an understanding confidant with whom one can share their worries may lower arousal and facilitate restful sleep ( 36 ). In a study of women aged 61 to 90, Friedman ( 66 ) found that participants who reported poorer sleep efficiency had higher levels of the inflammatory biomarker Interleukin-6 (IL-6); however, social supportterm·dom buffered the relationship between poor sleep and inflammation. In a cohort of the older Singaporeans, those with supportive social relationships measured as marital status, size of network, frequency of contact, and perceived closeness with relatives and friends outside the household, were less likely to experience cognitive decline from extreme sleep duration ( 57 ).
Physical and emotional well-being Socially-supported sleepterm·dom may contribute to physical and emotional well-being in older adultsterm·key. Social supportterm·dom and sleep qualityterm·dom are essential to adaptation and well-being in older adulthood ( 73 ). Poor sleep qualityterm·dom has a detrimental effect on both physical and emotional well-being; however, perceived social supportterm·dom may mitigate the detrimental effects of poor sleep qualityterm·dom on physical and emotional well-being in older adultsterm·key ( 76 ). High, stable levels of support from the spouse were found to attenuate the negative effects of rumination on sleep qualityterm·dom, reducing chronic stress and promoting emotional well-being ( 36 ). Socially isolated older adultsterm·key were more likely to report poor physical and psychological well-being compared to supported counterparts, which increased the risk of sleep difficulty ( 64 ). In a nationally representative longitudinal survey of community-dwelling older adultsterm·key, Cheng, Malhotra, and Chan ( 78 ) found that weak social networks and restless sleep reciprocally influence each other through depressed mood. Indeed, lack of social supportterm·dom and lower levels of physical and emotional well-being may both predict and serve as an outcome of poor sleep qualityterm·dom ( 56 , 68 , 69 , 74 ).
Quality of life Socially-supported sleepterm·dom may contribute to increased quality of life among older adultsterm·key. Cultivating social networks may benefit sleep and quality of life in older adultsterm·key ( 78 ). Sleep problems and negative changes in sleep patterns can have a harmful influence on quality of life. Older adultsterm·key with higher levels of social supportterm·dom may have more psychological resources and engage these resources more effectively despite adversity, thereby improving quality of life ( 76 ). Compared with older adultsterm·key reporting good sleep qualityterm·dom, those experiencing inadequate sleep were more likely to report lower perceived support, family involvement, self-related health, and hope ( 65 ). Continuous poor sleep qualityterm·dom may lead to a deterioration in psychological health, leading older adultsterm·key to withdraw from their social contacts, with diminished quality of life ( 73 ). The risk of sleep difficulty might be especially pronounced for older adultsterm·key who are socially isolated and suffering from multiple chronic conditions; isolation from social ties may negatively impact the sense of mattering and belonging central to quality of life ( 64 ).
Related concepts and definition Concepts related to socially-supported sleepterm·dom identified in this analysis were social well-beingterm·dom, social engagementterm·dom, and social frailtyterm·dom. While related concepts may also serve as protective social resources for healthy agingterm·key, each has distinct attributes. Social well-beingterm·dom refers to the appraisal of social expectations of the self and society and one’s circumstances and functioning in society ( 83 ). Social well-beingterm·dom reflects the ability to navigate society, and the extent to which they experience societal belonging, whereas socially-supported sleepterm·dom underscores quality relationships with close individuals. Social engagementterm·dom emphasizes community-based activities and interpersonal interactions based on resource sharing ( 84 ). Social engagementterm·dom reflects types of social groups and the frequency of engaging with social groups, rather than close relationships. Social frailtyterm·dom is understood in terms of social vulnerability in terms of social resources, social behaviors, and social activities ( 85 ). Social frailtyterm·dom provides a comprehensive view of social conditions, rather than addressing a single aspect, such as social supportterm·dom in close relationships.
Socially-supported sleepterm·dom has evolved from the conceptual basis of social supportterm·dom; relevant studies informed the attributes, antecedents, consequences, and definition of socially-supported sleepterm·dom in older adultsterm·key. The concept of socially-supported sleepterm·dom reflects the process of safe and secure, belonging and connection, and warmth and comfort, manifested in dimensions of improved sleep qualityterm·dom, and resulting in enhanced regulatory capabilities, physical and emotional well-being, and quality of life in older adultsterm·key aged 50 and older ( Figure 2 ).

Discussion Theoretical and clinical implications Older adultsterm·key are at high risk for poor sleep qualityterm·dom and associated risk for chronic illness and functional decline. While knowledge about the role of social supportterm·dom in sleep qualityterm·dom is growing ( 35 ), with calls for interventions to leverage social supportterm·dom to promote healthy agingterm·key ( 27 ), there remains a paucity of knowledge regarding ways to promote social supportterm·dom for sleep in older adultsterm·key. Socially-supported sleepterm·dom, a concept whose defining characteristics include promoting improved sleep qualityterm·dom by cultivating safe and secure, belonging and connection, and warmth and comfort may help to address this gap in the literature.
While social supportterm·dom as a concept relevant to older people and public health has evolved over decades, the development of socially-supported sleepterm·dom remains at the conceptual stage. Addressing the conceptual clarity of socially-supported sleepterm·dom provides an important step toward empirical testing in older adultsterm·key and meaningful public health research. The evolutionary method provides for concept analysisterm·key that promotes public health science and fosters conceptually sound research to improve clinical care ( 47 , 86 ). In its current state of development, socially-supported sleepterm·dom has the potential to inform subsequent research and theory development that build on and extend the concept. Further development and refinement of socially-supported sleepterm·dom may identify innovative and effective interventions to augment quality sleep in older adultsterm·key.
The focus of socially-supported sleepterm·dom antecedents of safe and secure, belonging and connection, and warmth and comfort may serve a key role in promoting healthy agingterm·key. Social supportterm·dom is essential for human survival, as it is central to the mutual exchange of protection, care, and resources ( 29 , 49 , 87 ). Future research may benefit from linking socially-supported sleepterm·dom to emergent mechanistic understandings of the social supportterm·dom effect on health and disease processes, which are linked to activation and inhibition of the autonomic nervous system via danger and safety signals ( 29 ). Safety signals are found primarily in close others as sources of predictability, protection, comfort, soothing and connection ( 88 ). Safety signals and experiences of safe and secure serve emotional and physiological regulatory functions across the lifespan ( 88 , 89 ). Research is needed to advance knowledge regarding these mechanisms as a basis for intervention.
The literature reviewed for this analysis has implications for future research and development within older people public health. While socially-supported sleepterm·dom attributes, antecedents, and consequences among older adultsterm·key add conceptual clarity, gaps in this literature include: (a) primarily cross-sectional research; (b) variable measures of sleep qualityterm·dom and duration; (c) limited use of objective measures of sleep, such as actigraphy and polysomnography; (d) limited specification of psychological and physiological mechanisms of action linking social supportterm·dom and sleep qualityterm·dom; and (e) lack of specificity in linking dimensions of support to specific sleep characteristics. The integrative review may have been limited by the keywords characterizing social supportterm·dom used in the study screening process. Future research expanding keywords to address the specific dimensions of social connectionterm·dom (structural, functional, or quality) relevant to dimensions of sleep qualityterm·dom will be essential.
Conclusion Poor sleep qualityterm·dom is prevalent in older adultsterm·key. Findings from this study provide a theoretical clarification of socially-supported sleepterm·dom in older adultsterm·key, which may raise awareness of sleep disturbances and the importance of assessing social supportterm·dom in the aging population. This concept analysisterm·key provides an important preliminary step in addressing conceptual clarity of socially-supported sleepterm·dom in the context of healthy agingterm·key, advancing a continuous process of development and scientific progress. Rodgers’ evolutionary method was used to investigate the concept of socially-supported sleepterm·dom, as its philosophical foundation emphasizes the dynamic nature and contextual dependence of concepts. Analyzing the evolution of socially-supported sleepterm·dom in older adultsterm·key and its attributes, antecedents, consequences, and definition clarifies the concept. Socially-supported sleepterm·dom is a concept relevant in older adulthood; continued development of socially-supported sleepterm·dom within older adultterm·key care may provide a foundation for research and practice promoting healthy agingterm·key.
