The Impact of Adolescents’ Social Skills on School Adjustment - The Mediating Effect of Subjective Well-Being and the Moderated Mediation Effect of Social Support -

The purpose of this study was to examine the effects of adolescents’ perceived social skills on school adjustment and to empirically identify the mediating effect of subjective well-being as well as the moderating and moderated mediating effects of social support in this relationship. To achieve this aim, the study targeted middle and high school students in Gyeonggi Province, South Korea. A total of 528 valid responses were collected through a survey conducted from March 31 to May 9, 2025. The main findings are as follows. First, social skills had significant positive effects on both subjective well-being and school adjustment. Second, subjective well-being significantly mediated the relationship between social skills and school adjustment. Third, social support moderated the relationship between social skills and subjective well-being, indicating that the positive effect of social skills on subjective well-being was stronger when social support was high. Fourth, social support also moderated the mediating effect of subjective well-being, confirming a significant moderated mediation effect in the relationship between social skills and school adjustment.
