Adolescence is a sensitive time frame during which individuals have to cope with numerous social, physical and psychological changes. For the adolescent, this period of dramatic challenge requires adjustment to changes in the self, in the family and in the peer group. It is thus assumed that during adolescence the self and personality are especially malleable. Hence, adolescence is a period of the lifespan that offers a unique window into developmental processes that may have long-term consequences for the individual well beyond the adolescent years. Although a great number of studies have investigated life consequences of individual’s level in the self and personality, almost no long-term research exists on the consequences of adolescent self and personality change/development. However, because adolescence is theoretically conceptualized as a transitional time period in which an enormous amount of change has to be processed, examining adolescent development and interindividual differences in the intraindividual development as predictors of long-term life outcomes is especially crucial. Furthermore, not only have developmental aspects of the self and personality largely been under-investigated but most longitudinal studies also only cover a short time period. Hence, further longitudinal analysis has to be conducted on consequences of the self and personality development over decades rather than years, namely across different age groups (adolescence, early and middle adulthood) and different generations (main cohort: 45 years, children: 12-17 years). Therefore, my research aims at extending the knowledge of adolescent development and its long-term consequences over three decades and at investigating transmission effects from one generation to the next within self and personality development. In line with these goals, unique features of the planned PhD thesis will be the consideration of change as a predictor of life outcomes, the long time span (over three decades) as well as the intergenerational approach to my analysis. To pursue my research goals I will use the existing data set of the LifE-study (Pathways from late childhood to middle adulthood ). This project was initiated in 1979 with well over 2,000 German pupils by Prof. Dr. Dr. h. c. Helmut Fend with a seventh assessment wave completed in 2012 during which I was part of the project team. The LifE-study is a 33-year longitudinal study covering sociological, psychological and educational topics in an interdisciplinary approach and offers a unique chance to study interindividual and intraindividual development across the lifespan.
