Background: Learning flow is an optimal learning experience representing full engagement in one's studies. The belief-affect-engagement model and control-value theory suggest that positivity would be a motivator of learning flow, while positive affect in school would be a mediator of the relation between positivity and learning flow. Aims: The…

Friendships affect children's development and adjustment. This longitudinal study examined the possible heterogeneity and gender differences in the trajectories of children's friendship quality, as well as the relations between distinct friendship quality trajectories and school adjustment. A total of 3,779 Chinese elementary school students…

Background: Parental involvement is an important multi-faceted factor in children's academic performance and school behaviour. However, most prior studies have involved cross-sectional designs, with few studies exploring the co-developmental nature of various parental involvement characteristics over time and their associations with children's…

This study explored the relations among peer victimization (i.e., physical, relational, and cyberbullying victimization), learning flow, and academic achievement among elementary school students, using a seven-wave longitudinal design across four consecutive semesters. Participants were 1,440 students from Grades 3 and 4 in China (M[subscript age]…

Background: The development of prosocial behavior is a significant aspect of children's social well-being. From the perspective of positive psychology, subjective well-being (SWB) "in school" is likely a particularly relevant construct in elementary school-aged children's prosocial development. Research on the relation between SWB in…

Gratitude is a human strength that is beneficial for psychosocial adjustment and academic adjustment. This study aimed to examine the (a) heterogeneity and gender differences in the developmental trajectories of gratitude to obtain a more nuanced understanding of the development of gratitude in children, and (b) relations between these…

This study aimed to identify multiple co-developmental trajectories of the three components (i.e., school satisfaction, positive affect in school and negative affect in school) of subjective well-being (SWB) in school and their relations to predictors and outcomes among Chinese elementary school students. A total of 2756 students (M[subscript age]…

Based on the self-system model of motivational development, we examined the mediating role of school engagement, including cognitive engagement and behavioral engagement, in accounting for the relation between mastery goal orientations and subjective well-being in school among elementary school students. A total of 974 Chinese children (440…

Based on expectancy-value theory, this longitudinal study was designed to test the relations between two achievement task values (i.e., attainment value and utility value) as well as their respective influences on academic achievement and depressive symptoms. This study incorporated a sample of 897 (M[subscript age] = 10.36 years, 55.8% male) and…

Situated within a positive psychology perspective, the current study examined the relations among academic achievement, self-esteem, and subjective well-being (SWB) in school among Chinese elementary school students using a longitudinal mediation model. A total of 807 elementary school students (M[subscript age] = 9.43 years; 52.9% male) completed…
