The big two personality traits and adolescents' complete mental health: The mediation role of perceived school stress.

Based on Greenspoon and Saklofske's (2001) dual-factor model of mental health, we defined adolescents' mental health as comprised of two distinguishable factors: positive and negative mental health. We tested the direct relations between the Eysenck's (1967) Big Two personality traits (Extraversion and Neuroticism) and positive and negative mental health, and explored the mediation effects of perceived school stress in accounting for the relations. Direct and indirect relations were estimated by using structural equation modeling with data from 1,009 Chinese adolescents in a 3-wave study. Results indicated that (a) adolescents' levels of neuroticism showed a positive relation to negative mental health and a negative relation to positive mental health, whereas levels of extraversion showed a negative relation to negative mental health and a positive relation to positive mental health; and (b) adolescents' perceived school stress (PSS) mediated the relation between neuroticism and mental health but not the relation between extraversion and mental health. The findings suggest that school professionals should consider adolescents' personality traits and school-based stress when planning and delivering mental health services. The findings of the relations between extraversion and PSS are also discussed in light of the face culture in China. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
