The study investigated the similarities between 55 delinquent, 46 low achieving (LA), 45 learning disabled (LD), and 30 normal achieving (NA) adolescents from grades 7 through 12 and their parents. Each adolescent and parent was given a questionnaire covering a wide variety of descriptive variables. In addition, data or grade point average, attendance, achievement, grade placement, and teacher ratings were collected for the delinquent group. Findings showed that Ss who had committed delinquent acts most resembled the LA group based on student and parent interview responses. Delinquent Ss generally indicated below average grade point average; however, achievement test scores were average. In addition, family relationships and difficulty in problem solving appeared to distinguish this group from LA, LD, and NA groups. It was concluded that factors other than learning problems may be intervening to cause delinquent behaviors. Statistical data corresponding to youth and parent questionnaire responses are presented.
