[Interventional gerontology in German-speaking countries: a social and behavioral science assessment]

This work is aimed at reviewing 20 years of gerontological intervention research within the social and behavioral domain in German speaking countries. Only controlled studies based on adequate measurement instruments are considered. Literature analyses reveal that the issue of cognitive intervention research is well-covered, underlining clear positive training effects in intellectual performance and memory. Also, studies on the limits of mental capacity represent a highlight of German cognitive training research. Another bunch of studies underlines the potential of different intervention to enhance independence in day-to-day function, social activity, and subjective well-being. Positive effects in self-concept, personal control, and attribution style are as well reported. A general discussion of this body of work leads to suggestions for future research priorities.
