Social capital has previously been reviewed in relation to mental health. However, none have focused specifically on positive aspects of mental health such as mental well-being. This review aimed to explore the relationship between social capital and mental well-being in older people. Ten relevant databases were systematically searched using an extensive search strategy for studies, analyzing the link between social capital and mental well-being. Criteria for inclusion in the systematic review were: the study sample included older people (≥50 years); the study reported a mental well-being outcome; social capital was an exposure variable; and empirical research using quantitative methods and published in English, between January 1990 and September 2011. Eleven studies met the inclusion criteria. Each study was assessed against seven possible exposure measures (structural, cognitive; bonding, bridging, linking; individual, collective). The results showed that all included studies found positive associations between parts of social capital and aspects of mental well-being. Typically, the relationship between social capital and mental well-being differed within as well as between studies. Our results highlight that there is no ‘gold standard’ of how to measure social capital or mental well-being. Social capital is generated in the interaction between individual and collective life. A possibility for future research is therefore to follow Bronfenbrenner's classical division into macro, meso, and micro levels. We consider family and friends at the micro level to be the key factors in generating social capital and well-being in older people.

Previous studies of loneliness have largely focused on establishing risk factors in specific age groups such as in later life or in young people. Researchers have paid less attention to the link between social capital and loneliness across different age groups. The aim of this study was to examine the association between social capital and experienced loneliness in different age groups in a Finnish setting. The data originates from a population-based cross-sectional survey conducted among 4618 people aged 15–80 in Western Finland in 2011. The response rate was 46.2 %. The association between social capital, measured by frequency of social contacts, participation in organisational activities, trust and sense of belonging to the neighbourhood and loneliness was tested by logistic regression analyses stratified by four age groups. Frequent loneliness (defined as experienced often or sometimes) was higher among younger people (39.5 %) compared to older people (27.3 %). Low levels of trust were linked to loneliness in all four age groups. The association between other aspects of social capital and loneliness varied across age groups. Frequent loneliness is common among the general adult population and could be seen as a public health issue. Our findings imply that low social capital, especially in terms of low trust, may be a risk factor for loneliness. However, further research is needed to assess the influence of poor health and reverse causality as explanations for the findings.

Background Observational studies show that social capital is a protective health factor. Therefore, we aim to assess the currently unclear health impact of social capital interventions targeting older adults. Methods We conducted a systematic review based on a logic model. Studies published between January 1980 and July 2015 were retrieved from MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials and Web of Science. We included randomised controlled trials targeting participants over 60 years old and focused on social capital or its components (eg, social support and social participation). The comparison group should not promote social capital. We assessed risk of bias and impact on health outcomes and use of health-related resources applying a procedure from the Canadian Agency for Drugs and Technologies in Health (CADTH) based on vote-counting and standardised decision rules. The review protocol was registered in PROSPERO (reference number CRD42014015362). Results We examined 17 341 abstracts and included 73 papers reporting 36 trials. Trials were clinically and methodologically diverse and reported positive effects in different contexts, populations and interventions across multiple subjective and objective measures. According to sufficiently reported outcomes, social capital interventions showed mixed effects on quality of life, well-being and self-perceived health and were generally ineffective on loneliness, mood and mortality. Eight trials with high quality showed favourable impacts on overall, mental and physical health, mortality and use of health-related resources. Conclusions Our review highlights the lack of evidence and the diversity among trials, while supporting the potential of social capital interventions to reach comprehensive health effects in older adults.

Objective: To study the association between structural and cognitive aspects of social capital and depression among older adults in two Nordic regions. Method: Data were retrieved from a postal survey targeting older adults aged 65, 70, 75 and 80 years (N = 6 838, response rate = 64%) residing in the Västerbotten region (Sweden), and the Österbotten region (Finland) in 2010. The associations between structural (measured by frequency of social contact with friends and neighbours) and cognitive (measured by experienced trust in friends and neighbours) aspects of social capital and depression (measured by Geriatric Depression Scale, GDS-4) were tested by logistic regression analyses. Results: Both low structural and cognitive social capital as defined in the study showed statistically significant associations with depression in older adults. Only experienced trust in neighbours failed to show significant association with depression. In addition, being single and being 80 years of age indicated a higher risk of depression as defined by GDS-4. Conclusion: The findings underline the connection between adequate levels of both structural and cognitive individual social capital and mental health in later life. They also suggest that the connection differs depending on various network types; the cognitive aspect of relationships between friends was connected to depression, while the connection was not found for neighbours. Further, the oldest age group in the sample (80 years of age) is pointed out as a population especially vulnerable for depression that should not be overlooked in mental health promotion and depression prevention.

Objective: The aim of this study was to investigate the association between aspects of social capital and loneliness among the very old living at home and in institutional settings. Method: Half of those aged 85 years, and all 90- and 95-year-olds and older in urban and rural municipalities in northern Sweden and western Finland were invited to participate in a cross-sectional population-based study in 2005-2007. A sample of 483 participants who completed the study was included in the analyses. Results: Loneliness was experienced by 55% percent of those living in institutional settings often or sometimes and 45% of those living in their own homes. Loneliness was closely related to living alone, to depression, and to region (northern Sweden). Discussion: Social capital and loneliness are context dependent (i.e., geographical or living environment). Among the very old, the link between social capital resources and loneliness is also highly influenced by health status.

The aim of this scoping review is to explore previous scientific studies relating to the scholarly understanding of societal participation of people with disabilities. Six relevant databases within social science were searched using societal participation of people with disabilities, or different combinations thereof, as search words. The criteria for inclusion were: working-age people with disabilities; societal participation; accounting for facilitators or/and barriers of participation; geographical focus on or link to Europe, peer-reviewed studies using quantitative or qualitative methods published in English between January 2012 and December 2013. Thirty-two studies met these inclusion criteria. Each study was analysed relating to four measures: identity of the participator group, type of participation; type of facilitators; type of barriers. The findings show that there is a dominating focus on labour market participation and that societal participation was studied mostly concerning disabled people in general instead of any specific group. The main barriers identified were related to financial factors, attitudes, health issues and unemployment. The most frequently identified facilitators were related to legislation and disability policies, as well as to support from people in close contact with disabled people, attitudes in society and employment opportunities for people with disabilities.
