A sample of 483 male students in grades 10 and 11 in 4 high schools were administered a group-interview-questionnaire. It measured the relationships between their delinquency patterns and variables such as family structure characteristics; area and type of residences; parent-child type of relationships; friends' delinquent acts; delinquent accomplices; and reasons for committing delinquent acts. The results showed three delinquency patterns: auto offenses, vandalism, and kissing and/or touching a female. The respondents were classified into mild (1), moderate (2), and serious (3) delinquent type on the basis of frequency and kind of delinquent acts, number of accomplices, friend's degree of delinquency, and reason for delinquent acts. Type 3 delinquents ranked lower on family and residential characteristics such as income, rental housing, closeness to father, and frequent parental punishment than did types 1 and 2. Overall, this Kuwait sample appears to be similar to the samples researched in the United States. 1 table and 44 references (Author abstract modified)
