Abstract: Abstract Various aspects of early adolescence can have a key impact on adult life satisfaction. This study applied a growth mixture model to examine the trajectories of early adolescents’ life satisfaction and test the effects of individual (sex, subjective achievement, and self-esteem) and social factors (school adjustment and peer attachment) thereon. For this purpose, a growth mixture model was used on the fifth- (grade five), sixth- (grade six), and seventh- (grade seven) year panel data of 1917 grade one students from the Korean Children and Youth Panel Survey (2010–2016, National Youth Policy Institute), excluding missing samples. Participants were 990 boys (51.6%) and 927 girls (48.4%). The results indicated that the trajectories of life satisfaction could be categorized into three groups: “High Level-decreasing” (57.19%), “Moderate Level-stable” (37.62%), and “Low Level-increasing” (5.19%). Predictors for each class exhibited that female students and individuals with higher levels of self-esteem and school adjustment were more likely to be in the “Low Level-increasing” and “Moderate Level-stable” groups compared to male students and those reporting lower levels of self-esteem and school adjustment. Moreover, students with higher peer attachment were more likely to be in the “Low Level-increasing” group compared to the “High Level-decreasing” group. Educational implications to achieve positive life satisfaction by determining the influence of the predictors for each trajectory are outlined.
