Personality development in adolescence: Examining big five trait trajectories in differential learning environments

This study addresses two questions: Do Big Five traits change from early to middle adolescence? How do developmental trajectories differ between educational environments (i.e., secondary school tracks)? We used a representative random sample from Germany, following 6th graders (T1, N = 1662; age: M = 11.68; SD = 0.63; female = 47.4%; from N = 87 primary schools) to the end of compulsory secondary education over three measurement points (i.e., assessing students in 6th, 7th, and 9th grade). Results of latent change modeling indicated overall increases in mean levels for all personality traits from early to middle adolescence. Regarding selection effects, the results indicated that more conscientious, agreeable, extraverted, open, and emotionally stable sixth graders were more likely to transit into an academic rather than a non-academic secondary school track. Moreover, the results showed that these initial differences in personality traits seemed to diminish between 6th and 9th grade for all personality traits. Additionally, controlling for selection effects, a contextual effect was discernible for conscientiousness. This study highlighted the potential role of differential learning environments for modifying changes in personality traits during adolescence.
