SUBJECTIVE WELL-BEING AND SOCIAL PRODUCTION FUNCTIONS

Recent reviews of scientific work on subjective well-being (SWB) reveal disagreements in conceptualization, measurement, and explanation of the concept. We propose Social Production Function theory as a framework to resolve them. Social Production Function (SPF) theory integrates strengths of relevant psychological theories and economic consumer/household production theories, without their limitations (namely, tradeoffs between satisfaction of different needs are not in the first, and goals or needs are not in the second). SPF theory identifies two ultimate goals that all humans seek to optimize (physical well-being and social well-being) and five instrumental goals by which they are achieved (stimulation, comfort, status, behavioural confirmation, affection). The core notion of SPF theory is that people choose and substitute instrumental goals so as to optimize the production of their well-being, subject to constraints in available means of production. SPF theory guides research measurement and explanatory models, and it integrates features of contemporary subjective well-being theories.

Which social needs are important for subjective well-being? What happens to them with aging?

In this study the authors investigated how satisfaction levels of affection, behavioral confirmation, and status, as three human social needs, relate to age, physical loss, and subjective well-being. Results (N=883, aged 65 to 98 years) revealed that (a) affection was relatively high and status was relatively low in all age and loss groups; behavioral confirmation showed negative age and loss effects but was better predicted by loss; (b) the three needs relate differentially to indicators of subjective well-being: affection and behavioral confirmation relate positively to life satisfaction; status and behavioral confirmation relate positively to positive affect and negatively to negative affect. It is concluded that the need for behavioral confirmation is more difficult to satisfy with high physical loss, but none of the three social needs becomes less important with advancing age.

Forever young? A comparison of age identities in the United States and Germany

This study compares age identities of middle-aged and older adults in the United States and Germany. Differences between countries in social systems and cultural meanings of old age are expected to produce different age identities. Data are from respondents between ages 40 and 74 in the United States (MIDUS; n = 2,006) and Germany (German Aging Survey; n = 3,331). Americans and Germans tend to feel younger than their actual age, but the discrepancy is larger among Americans. The bias toward youthful identities is stronger at older ages, particularly among Americans. In both counties, persons with better health have younger identities and role losses are not related to age identities. The study shows that different social and cultural systems produce different subjective experiences of aging. As these differences exist within Western culture, the study makes clear that one should be careful in generalizing findings from aging research across countries.

How to understand and improve older people’s self-management of wellbeing

This paper addresses the question of how older people can be supported to actively self-manage their own process of ageing such that overall wellbeing is achieved and maintained for as long as possible. Starting from a resource-based approach, a new theory of self-management of wellbeing (SMW theory) is proposed, and it is shown how it can be used as a basis for the design of self-management interventions for ageing successfully. The main aspects of the theory, i.e. six key self-management abilities and the core dimensions of wellbeing, are presented as well as the theory-based ‘blueprint’ for the design of interventions. Empirical results of two intervention studies are briefly presented and show that the SMW theory may be a useful tool for the design and evaluation of interventions for successful ageing.

Finding a useful conceptual basis for enhancing the quality of life of nursing home residents

In this article it is depicted that before nursing home staff can effectively contribute to optimising the quality of life (QOL) of nursing home residents, it has to be clear what exactly QOL is and how it can be enhanced. The aim is to identify a QOL framework that provides tools for optimising QOL and can form the basis for the development of guidelines for QOL enhancement. For that purpose, a framework should meet three basic criteria:(1) it should be based on assumptions about comprehensive QOL of human beings in general; (2) it should clearly describe the contribution of each dimension to QOL and identify relationships between the dimensions; (3) it should take individual preferences into account. After the criteria are defined, frameworks identified from a literature search are discussed and evaluated according to these criteria. The most suitable framework appears to be the QOL framework of the theory of Social Production Functions. The implications of this framework in understanding the QOL of nursing home residents are described and recommendations for further research are discussed.

The effect of social comparison information on the life satisfaction of frail older persons

In this study, the authors examined the effects of social comparison on the life satisfaction of 455 community-dwelling older persons. These older persons were confronted with a fictitious interview with either an upward or a downward target. After downward comparison, older persons felt more satisfied with their lives than after upward comparison, especially those who had higher levels of frailty. These effects were only found with lower levels of identification. Apparently, downward comparison only serves its self-enhancing function on life satisfaction among frail older persons when they perceive the comparison target as different from themselves.

Does Loneliness Mediate the Relation between Social Support and Cognitive Functioning in Later Life

Research in gerontology has demonstrated mixed effects of social support on cognitive decline and dementia: Social support has been shown to be protective in some studies, but not in others. Moreover, little is known about the underlying mechanisms between social support and cognitive functioning. We investigate one of the possible mechanisms, and argue that subjective appraisals rather than received amounts of social support affect cognitive functioning. Loneliness is seen as an unpleasant experience that occurs when a persons network of relationships is felt to be deficient in some important way. As such, loneliness describes the extent to which someones needs are not being met and thus provides a subjective assessment of support quality. We expect that receiving instrumental and emotional support reduces loneliness, which in turn preserves cognitive functioning. Data are from the Longitudinal Aging Study Amsterdam (LASA) and include 2255 Dutch participants aged 55-85 over a period of six years. Respondents were measured every three years. Cognitive functioning was assessed with the Mini-Mental State Examination (MMSE), the Coding Task, and the Ravens Coloured Progressive Matrices. The analytical approach comprised latent growth mediation models. Frequent emotional support related to reduced feelings of loneliness and better cognitive functioning. Increases in emotional support also directly enhanced cognitive performance. The protective effect of emotional support was strongest amongst adults aged 65 years and older. Increase in instrumental support did not buffer cognitive decline, instead there were indications for faster decline. After ruling out the possibility of reversed causation, we conclude that emotional support relationships are a more powerful protector of cognitive decline than instrumental support relationships.

A revised index for social engagement for long-term care

The objective of this study was to improve validity and reliability estimates of the Index for Social Engagement (ISE) for long-term care. After exploring content validity and internal consistency in Dutch and Canadian data, two ISE items were dropped, and two new items were added. Reliability of this Revised ISE (RISE) was tested in 189 nursing home residents. It appeared that the RISE has enhanced reliability estimates, especially in residents with cognitive impairment. The RISE for long-term care improves the existing index by including additional dimensions of social engagement and by increasing the reliability of results for residents with cognitive impairment.

Validation of the self-management ability scale (SMAS) and development and validation of a shorter scale (SMAS-S) among older patients shortly after hospitalisation

BackgroundThe 30-item Self-Management Ability Scale (SMAS) measures self-management abilities (SMA). Objectives of this study were to (1) validate the SMAS among older people shortly after hospitalisation and (2) shorten the SMAS while maintaining adequate validity and reliability.MethodsOur study was conducted among older individuals (≥ 65) who had recently been discharged from a hospital. Three months after hospital admission, 296/456 patients (65% response) were interviewed in their homes. We tested the instrument by means of structural equation modelling, and examined its validity and reliability. In addition, we tested internal consistency of the SMAS and SMAS-S among a study sample of patients at risk for cardiovascular diseases.ResultsAfter eliminating 12 items, the confirmatory factor analyses revealed good indices of fit with the resulting 18-item SMAS (SMAS-S). To estimate construct validity of the instrument, we looked at correlations between SMAS subscale scores and overall well-being scores as measured by Social Product Function (SPF-IL) and Cantrils ladder. All SMAS subscales of the original and short version significantly correlated with SPF-IL scores (all at p ≤ 0.001) and Cantrils ladder (for the cognitive well-being subscale p ≤ 0.01; all other subscales at p ≤ 0.001). The findings indicated validity. Analyses of the SMAS and SMAS-S in the sample of patients at risk for cardiovascular diseases showed that both instruments are reliable.ConclusionsThe psychometric properties of both the SMAS and SMAS-S are good. The SMAS-S is a promising alternate instrument to evaluate self-management abilities.

Improved self-management ability and well-being in older women after a short group intervention

In the present randomized controlled trial (RCT) it was investigated whether single women, 55 years of age and older, improved with regard to self-management ability, well-being, and social and emotional loneliness after having participated in a newly designed self-management group intervention based on the Self-Management of Well-being (SMW) theory. The expected mediating effect of self-management ability on well-being was not found. Although self-management ability, well-being and loneliness improved significantly in the intervention group immediately after the intervention, and also remained at this improved level after six months, there was also improvement in the control group after six months, rendering the longer-term differences between the groups non-significant. It can, however, be concluded that, although the longer-term effectiveness could not be proven, this SMW theory-based intervention seems to be useful in supporting older women to improve their self-management ability and well-being.
