The aim of this self-report study is to analyze proposed interrelations between value orientations, self-control, frequency of school-leisure conflicts, and life-balance in adolescence. Life-balance is defined as satisfying time investment in different life areas. The tested model posits that self-control is negatively related to conflict frequency and that the latter is negatively related to life-balance. Achievement and well-being value orientations, in turn, should be connected to the degree of self-control and the frequency of goal conflicts. In the study, 817 German 8th-graders with a mean age of 13.4 years participated. Results from structural equation modeling supported the proposed model. The results suggest that fostering self-control can be a promising approach to decrease the frequency of goal conflicts, and thus increase students' experience of life-balance.
