We examined the influence of individual views of aging on health changes in later life. We hypothesized that aging-related cognitions affect health changes irrespective of control beliefs and that the impact of aging-related cognitions on health is higher than for the reverse direction of causality. We based our analyses on data from the longitudinal part of the German Aging Survey (N = 1,286; participants were 40-85 years of age at baseline). Because of the selectivity of the sample, we also computed the same analyses for the baseline sample (N = 4,034) with estimated Time 2 data for those individuals who dropped out. The results of structural equation modeling were concordant with our hypotheses, and therefore they corroborate previous findings on the importance of beliefs about aging.

Using data from a computer‐based formative feedback system, we compare learning gains in the 8 weeks of school closures related to the COVID‐19 pandemic in Switzerland with learning gains in the 8 weeks before these school closures. The school performance in mathematics and language of N = 28,685 pupils is modelled in second‐order piecewise latent growth models with strict measurement invariance for the two periods under investigation. While secondary school pupils remain largely unaffected by the school closures in terms of learning gains, for primary school pupils learning slows down and at the same time interindividual variance in learning gains increases. Distance learning arrangements seem an effective means to substitute for in‐person learning, at least in an emergency situation, but not all pupils benefit to the same degree.

Physical activity is one of the most important health behaviours associated with the prevention and management of chronic diseases in older adults, but this potential is often insufficiently used. The present study examined for the first time whether a positive view on ageing (PVA) may contribute to a higher level of physical activity. Analyses were based on the German Ageing Survey, a longitudinal population-based survey (N = 4034) on middle-aged and older adults (40-85 years) conducted in the years 1996 and 2002. As hypothesised, middle-aged adults with a PVA not only engaged in physical activity in the form of sports more frequently; they even increased this activity provided that they were healthy enough to do so. For older adults, PVA was particularly associated with more regular walking and increases of walking over time. Because walking is often still recommended in spite of health problems, it was remarkable that even older people with worse health walked just as regularly as those with good health, provided that they had a positive view on ageing. The results shed some light on recent findings about the importance of PVA for health and longevity and point to a partial mediation between PVA and health by physical exercise.
