Abstract
This study classified 1,260 elementary and junior high school students aged 6–15 years into four leisure activity
patterns—game-focused, study-focused, balanced, and low-activity—and examined their associations with depressive symptoms and
gaming disorder severity. The results indicated that depressive symptoms were higher in the low-activity and balanced groups and
lowest in the study-focused group. Gaming disorder severity was lower in the study-focused group, whereas similarly elevated levels
were observed in the game-focused, balanced, and low-activity groups. These findings suggest that the amount of leisure activity and
participation in structured activities may play an important role in adolescents’ psychological adjustment.
