This study empirically examines the effects of mental stress on adolescents’
aggressive behavior by associating it with leisure participation types: passive, active,
and social leisure participations. For this examination, we use the data set of 2,448
male and female middle school student data of KYPS. The following results are
obtained: first, there is a positive relationship between the aggressive behavior and
the mental stress, social leisure participation, or low school performance. On the
other hand, there is a negative relationship between the aggressive behavior and the
passive leisure participation relative to the active leisure participation. Second, the
lower is the school performance, the more aggressive behavior is associated, and the
more aggressive behavior is observed, as the mental stress or social leisure
participation is more observed. Third, irrespective of the types of leisure
participation, the aggressive behavior consistently increases as the mental stress level
increases, and furthermore, this aspect is more evident when the students are
associated with social leisure participation. In the end, the effect of the mental stress
on the aggressive behavior is dependent upon the middle students' type of leisure
participation.
