[Gerontological research in social and behavioral sciences in Germany since 1968 : Review, critical assessment and perspectives]. / Gerontologische Forschung im Bereich der Sozial- und Verhaltenswissenschaften in Deutschland seit 1968 : Rückblick, kritische Würdigung und Perspektiven.

This article addresses the development of German social and behavioral aging research during the last 50 years based on four propositions: (a) the development and unfolding of social and behavioral aging research in the 1960s and 1970s was tedious. (b) During the 1980s and 1990s the significance of social and behavioral aging research grew considerably. (c) The last 20 years brought increasing and strong recognition of social and behavioral aging research. (d) Currently, social and behavioral aging research in Germany follows high and internationally established standards, and findings are published in internationally recognized journals. In a resume and outlook the structural aspects, future research topics, funding dynamics, and issues of the application of social and behavioral aging science are discussed.

Perceived control across the second half of life: The role of physical health and social integration.

Perceived control is a key component of successful aging and may serve as a protective factor against age-related declines in central domains of functioning. However, it is a largely open question whether and how perceived control changes from midadulthood to very old age and how such change is shaped by health and social contexts. To examine these questions, we apply growth models to up to 15-year 4-wave longitudinal data from the German Ageing Survey (DEAS; N = 10,081; aged 40-85 years at baseline; 49% women). Results revealed that perceived control is relatively stable in midlife, but starts to decline after midlife. Starting at 70, perceived control declines an average of a quarter of a SD per 10 years. Suffering from comorbidity and functional limitations were each associated with considerably lower perceived control. Volunteering and less loneliness were each uniquely associated with higher perceived control, over and above the other social factors as well as sociodemographic and health variables. Surprisingly, less social support was associated with stronger perceived control. We also found significant interaction effects suggesting that the combination of functional limitations with older age and loneliness with lower education were each associated with particularly compromised perceived control. Overall we found little evidence for correlates of change in perceived control, with only the loneliness-control association becoming slightly weaker over time. We take our findings to suggest that various different facets of social integration later in life are uniquely relevant for perceived control and suggest routes for further inquiry.

Toward a More Comprehensive Concept of Successful Aging: Disability and Care Needs.

Rowe and Kahn's model of Successful Aging 2.0 argues that changing environmental settings, societal policies, and individual life styles will lead to a significant extension of healthy life years. Recent epidemiological research, however, confirms the dilemma that the ongoing extension of life expectancy prolongs not only the years in good health but also those in poor health. We see it as a major limitation that Rowe and Kahn's model is not able to cover the emerging linkage between increasing life expectation and aging with disability and care needs. Therefore, we suggest a set of propositions towards a more comprehensive model of successful aging which captures desirable living situations including for those who grow old with disabilities and care needs. We describe individual, environmental, and care related strategies and resources for autonomy and quality of life when facing disabilities and care needs in late life, putting emphasis on inter-individual differences and social inequality. We argue that expanding the traditional concept of successful aging to aging with disabilities and care needs serves not to undermine, but rather to anchor the concept in aging science and in public perception.

Regional resources buffer the impact of functional limitations on perceived autonomy in older adults with multiple illnesses.

Retaining perceptions of autonomy is a key component of successful aging. Perceived autonomy refers to the capacity to make and enact self-directed decisions. These perceptions are often threatened in older adults with multiple illnesses, when functional limitations resulting from these illnesses impede the enactment of self-directed decisions. Regional resources (in Germany specifically at the level of administrative districts) might counteract these impediments of autonomy. Economically stronger districts can provide more-concrete support resources for older adults, buffering the negative effect of functional limitations on self-perceived autonomy. This study assessed participants aged over 65 with 2 or more chronic conditions. In total, N = 287 provided data (Mage = 73.3, SD = 5.07), and n = 97 were women. Gross domestic product (GDP) per capita was used as a proxy measure of administrative district wealth in Germany. Hierarchical multilevel regression analyses with cross-level interactions were conducted. Results suggest that the detrimental effect of functional limitations on perceived autonomy is less pronounced for participants residing in higher GDP districts. Conversely, for participants in lower GDP districts, the effect is exacerbated. This finding suggests that districts with greater financial resources might be better able to invest in supports that promote and facilitate autonomy and, thus, provide a buffer against threats to individual perceived autonomy.

Contextual and individual predictors of physical activity: Interactions between environmental factors and health cognitions.

OBJECTIVE: Although health behavior theories assume a role of the context in health behavior self-regulation, this role is often weakly specified and rarely examined. The two studies in this article test whether properties of the environment (districts) affect if and how health-related cognitions are translated into physical activity. METHODS: Multilevel modeling was used to examine the assumed cross-level interactions. Study 1 is a large-scale survey representative of the German adult population (N = 6,201). Gross domestic product (GDP) on the level of administrative districts was used to indicate environmental opportunities and barriers. Study 2 examined cross-level interactions of proximal predictors of physical activity (intentions, action planning, and coping planning) in older adults with multiple illnesses (N = 309), a high-risk group for health deteriorations. RESULTS: Study 1 showed that on the individual level, health attitudes (B = .11) and education (B = .71) were significantly associated with physical activity. GDP moderated the attitudes-behavior relation (B = .01), with higher attitude-behavior relations in districts with higher GDP. Study 2 finds that intention (B = .16), action planning (B = .17), and coping planning (B = .13) significantly predict activity. In addition, district-level GDP significantly moderated the relations between action planning and coping planning, but not intention, on physical activity. CONCLUSIONS: Results suggest that the effects of health attitudes and planning on physical activity are moderated by environmental factors. Districts with higher GDP provide better contextual opportunities for the enactment of concrete if-then plans for physical activity. This has implications for both theory and health promotion.

Resources for health: differential effects of optimistic self-beliefs and social support according to socioeconomic status.

OBJECTIVE: This study examined whether socioeconomic status (SES) determines the degree to which psychological and social resources such as optimistic self-beliefs and social support affect health. DESIGN: We used data from the representative German Ageing Survey (N = 2,454, aged 40-85 years). Structural equation modeling was employed to examine whether relationships between psychological (self-esteem, control beliefs, optimism) and social resources (perceived emotional and informational support, network size) and health differ between education and income groups. MAIN OUTCOME MEASURES: Self-reported physical health, functional health, and subjective health. RESULTS: Psychological resources positively affected health in all groups but were stronger predictors of functional and subjective health in low compared to higher educated participants. A higher level of social resources was associated with better functional and subjective health mainly in the low-income group. Social resources were particularly important for financially disadvantaged older people. CONCLUSION: Our results provide evidence for differential effects of optimistic self-beliefs and social support on health depending on whether individuals are challenged by low incomes or low education. Future research, especially aimed at intervention, should consider that different aspects of SES have differential meanings and that the impact of health-protective factors may vary according to SES facet.

Socioeconomic status and health in the second half of life: findings from the German Ageing Survey.

This study examined social inequalities in health in the second half of life. Data for empirical analyses came from the second wave of the German Ageing Survey (DEAS), an ongoing population-based, representative study of community dwelling persons living in Germany, aged 40-85 years (N = 2,787). Three different indicators for socioeconomic status (SES; education, income, financial assets as an indicator for wealth) and health (physical, functional and subjective health) were employed. It could be shown that SES was related to health in the second half of life: Less advantaged persons between 40 and 85 years of age had worse health than more advantaged persons. Age gradients varied between status indicators and health dimensions, but in general social inequalities in health were rather stable or increasing over age. The latter was observed for wealth-related absolute inequalities in physical and functional health. Only income-related differences in subjective health decreased at higher ages. The amount of social inequality in health as well as its development over age did not vary by gender and place of residence (East or West Germany). These results suggest that, in Germany, the influence of SES on health remains important throughout the second half of life.

Social inequality in the later life: cross-national comparison of quality of life.

This paper analyses quality of life and inequality in old age in an international comparative and a life course perspective. Quality of life is seen as an outcome of unequal chances in life. We distinguish between overall and domain specific expressions of quality of life which allows us to analyse the determinants of overall quality of life and their development over the life course. The data presented come from the research project "OASIS - Old Age and Autonomy: The Role of Service Systems and Intergenerational Family Solidarity". This data set is based on an age stratified random sample of the urban population (25-102 years) in Norway, England, Germany, Spain, and Israel (n=6,106). With advancing age, there are decreasing mean levels and increasing variation of quality of life. With age, the impact of physical health on overall quality of life increases, while the predictive power of other domains decreases. The results support the hypothesis of differentiation as well as the age-dependency hypothesis. For both these both aspects, international comparisons show similar results in different societies. These uniform age tendencies in modern European societies point to a limited importance of societal embeddedness and support the interpretation of age group differences as being life course effects.

Establishing systems of care in Germany: a long and winding road.

Since 1995/1996 a long-term care insurance (LTCI), which promised to develop new support structures, in particular for the group of potentially frail elderly people, has been implemented in Germany. It will be shown that this LTCI has undoubtedly improved the social situation of the persons in need of care, even if its scheme is only providing basic support with a ceiling in cash-benefits and benefits in-kind, and privileging home care by informal caregivers. But certain misdevelopments in the LTCI have shown that the present scheme requires further effort to cope with these negative effects and to elaborate new integrated models of care that bridge the still existent gap between medical and social support. This article points to long traditions of separating the social and medical dimensions in Germany which have also resulted in divided institutional arrangements. The current scheme of the LTCI, its organizational principles and its entitlements and benefits are outlined, which gives the opportunity to point out certain deficiencies, e.g., the still inappropriate provision for dementia care which is due to the dominant IADL-orientation of the medical assessment procedure and its implicit negligence of social care elements. The public debate about necessary improvements in benefits for the demented aged has already led to slight revisions of the LTCI, and will develop into a more comprehensive movement to path-bridging models of social and medical care in which the quality dimension will play a decisive role.
