The problem areas examined in this study related to school achievement, relationships with parents, anxiety over social and academic issues, and experience of serious illness or hardship. In general, students seemed to experience the greatest difficulties between their first and second year of junior high school. Self-reported delinquency was measured by involvement in 15 types of law-breaking and school misbehaviors. The most frequently reported types of delinquent behavior included drinking, breaking school regulations, truancy, loitering in town with friends late at night, and smoking cigarettes. Involvement in these activities also increased between the first and second year of junior high school. The correlation between the two types of behaviors examined here became stronger in each school grade. 8 tables, 1 figure, and 1 appendix
