One hypothesis tested is that social bonding variables predict variations in general delinquency involvement among Turkish, Surinamese, Moroccan, and Dutch male youth. A second hypothesis is that social bonding variables predict variations in a variety of types of delinquency involvement and deviance among these youth.

The primary data- collection instrument was a standardized questionnaire that included questions on beliefs, family, school, leisure-time activities, and delinquency.
