Using data from a sample of 754 middle school students in Grades 7 and
8, this article examines the independent effects of the four componen
ts of the school social bond-school commitment, attachment to school,
school involvement, and belief in school rules-on school crime, school
misconduct, and school nonattendance. The results suggest that person
al background, family involvement in schooling, and ability grouping h
ave differential effects on the school bond components. Also, an exami
nation of the independent effects of the four components of the school
social bond suggests that certain components are more important than
others in controlling different types of school delinquency. These res
ults suggest that the school social bond is an important intervening m
echanism that helps to explain the effects of certain predictor variab
les on school crime, school misconduct, and nonattendance in middle sc
hools.
