- Objectives. The purpose of this article is to examine data quality, reliability, and construct validity of the Older Americans Resources and Services social resources scale in six European countries (The Netherlands, Luxembourg, Italy, Austria, the United Kingdom, and Sweden).Methods. A questionnaire was administered through face-to-face interviews in five countries, and postal interview in the sixth, to representative populations of adults aged 50 to 90 living independently (N = 12,478). This article examines missing values and distribution of items in the social resources scale, and consistency of skew and kurtosis across countries. We performed item–total correlations and ran confirmatory factor analyses to test a three-factor model obtained in previous U.S. and Spanish analyses. Cronbach's alpha determined the reliability of the factors.Results. We observed a relatively large proportion of missing data for one item (have someone who would help you). All items correlated with a score equal to or greater than 0.20. Although the confirmatory factor analyses generally supported the acceptability of the three-factor structure in the European data, the reliability of two dimensions (dependability and affective) was unacceptably low.Discussion. Differences across countries make it unlikely that researchers can develop a single social resources scale that would have item equivalence in multiple countries.

- We used data from the Betula Study to examine associations between total cholesterol, triglycerides, and apolipoprotein E on 10-year changes in cognitive performance. Tests assessing episodic memory (recall and recognition), semantic memory (knowledge and fluency), and visuospatial ability (block design) were administered to 524 nondemented adults (initial age of 55-80 years); multilevel modeling was applied to the data. Higher triglyceride levels were associated with a decline in verbal knowledge. Lipid levels moderated the influence of apolipoprotein E on episodic memory, such that among epsilon 4 allele carriers, decline in recognition was noted for individuals with higher cholesterol levels. Cholesterol and triglyceride levels are pharmacologically modifiable risk factors that account for variation In normal cognitive aging.

- Objectives This study examined the association between childhood living conditions, socioeconomic position in adulthood, and cognition in later life. Two questions were addressed: Is there an association between childhood living conditions and late-life cognition, and if so, is the association modified or mediated by adult socioeconomic position?Methods Nationally representative data of the Swedish population aged 77 years and older were obtained from the 1992 and 2002 Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD). Cognition was assessed with an abbreviated version of the Mini-Mental State Examination scale. Childhood living conditions were assessed by self-reports of childhood living conditions.Results The results showed independent associations between conflicts in the household during childhood, father's social class, education, own social class in adulthood, and cognition in later life. Exposure to conflicts during childhood, having a father classified as a manual worker, low education, and/or being classified as a manual worker in adulthood was associated with lower levels of cognition in old age. There seemed to be no modifying effect of adult socioeconomic position on the association between childhood conditions and cognition in later life.Discussion This suggests the importance of childhood living conditions in maintaining cognitive function even in late life.

Do private intergenerational transfers from elderly parents increase social inequality among their middle-aged children? Evidence from the German Ageing Survey
- 2005

- Objectives. This study examines the consequences of private intergenerational transfers from elderly parents to their middle-aged children with respect to social inequality within the children's generation.Methods. With use of the nationally representative cross-sectional sample of the German Aging Survey, descriptive analyses as well as multivariate logistic regressions are used to identify the effects of three different types of private intergenerational transfers in the middle-age group (40–54 year olds, n = 1,719 for inter vivos and n = 1,446 for mortis causa transfers).Results. Transfers from parents or parents-in-law during the last 12 months—many of them smaller ones—are not significantly related to children's income. Separated and divorced children have significantly higher probabilities of receiving such transfers, indicating a need-directed family transfer process. Larger transfers before the last 12 months are need directed as well and moreover positively related to income position. Bequests, finally, are positively related to income position while having no need component at the time of observation.Discussion. Whereas larger monetary transfers and bequests may increase social inequality in the children's generation, a substantial part of the regular monetary flow from elderly parents to their adult children buffers situations of need. Public policy should take into account these different effects. Reducing the general level of public pensions would weaken regular transfer giving and thus lead to more inequality in the children's generation. Higher taxation of very large transfers and bequests would have the opposite effect.
