Abstract: Current research on successful aging reflects a multicriteria approach, although a consensus on the interrelationship between different factors has not yet been achieved. The longitudinal-sequential study presented here aims at identifying psychological, biological and sociobiographical predictors of well-being, health and autonomy in old age and their interdependency. The concern of this study is thus a multidisciplinary approach including psychology, psychiatry, geriatrics and sports sciences. The ongoing study is described and first findings are reported. Four hundred and forty-two people, aged 65 to 94, were tested twice (1993 and 1995). Since this project is a pursuit of a medical longitudinal study (Basler-Studie), bio-medical parameters from former status measurements (1960, 1965, 1971, 1985, 1990) are available and taken into account for comparison with the newly collected data from 1993 and 1995. The tests included both a medical examination and cognitive and personality measurements. The medical test battery included: clinical and anthropometrical data, bio-chemical data as well as the medical history, health behaviour, complaints and subjective health. The psychological assessment included psychological well-being, health-related control beliefs, causal attribution, religiosity, etc. For memory assessment a computerized test was used which allows to test 1) perceptual error-scanning, 2) naming speed, and memory resources in terms of 3) capacity, 4) explicit and 5) implicit components. It therefore integrates direct (free recall, recognition) and indirect memory tests (perceptual identification: clarification), that were used previously in different experimental and quasi-experimental studies to investigate memory performance over the life-span. Furthermore, the following three experimental interventions are perfomed: memory and reattribution training, physical training and psychoanalytical group therapy. First descriptive results are presented concerning age-correlated changes in biological and medical parameters, health behavior, cognitive performances and psychological well-being and functional autonomy. The results show the strongest age effects in the cognitive variables (with the exeption of priming). Beside age effects in speed variables and episodic memory we also find an age-correlated decline in semantic memory. Psychological well-being however, is not affected by age.
