The longitudinal interplay of personality and school experiences in adolescence

Abstract

The school environment is one key developmental context that is assumed to shape individual characteristics during adolescence. However, little is known about which school experiences are central to personality change or whether school experiences and personality co-shape each other over time. We address this gap by examining the longitudinal interplay between seven school experiences in the three domains of achievement, social relationships, and well-being, and the Big Five personality traits at four measurement points from fifth to eighth grade. By using data from the German TRAIN study ( N = 3,473, MageT1 = 11.1 years, 45% female), we estimated bivariate latent growth curve models and cross-lagged panel models to illustrate this longitudinal interplay. Results demonstrated correlated change between school experiences and personality with differentiated patterns for achievement variables and a general longitudinal interplay with the social relationship and well-being variables. Furthermore, we found cross-lagged effects in both directions, although there were more effects of personality on school experiences. The most consistent predictor of school experiences was conscientiousness, whereas well-being in school in particular was related to personality change 1 year later. We integrate our findings into the current picture of personality development in adolescence and the role of school-related environmental factors.
