Abstract
Data were analyzed for a random sample of sixty-four juvenile participants who completed the program between January 1, 1977 and April, 1978 and a random sample of forty-seven juvenile participants who completed the program between May, 1978 and August, 1979. In order to assess program impact, all the juvenile participants are administered a pretest during the first JIP session and a posttest after the last session. Follow-up data on impact measures are collected six months after program completion. In addition, participants are asked to complete a one-page questionnaire assessing their participation at the completion of each of the seven JIP sessions.
Analysis of the data indicates that the program positively affected family communication patterns, self-esteem levels and drug knowledge levels at follow-up. The follow-up data indicated that drug-related school system and drug-related criminal justice system contacts were significantly reduced. The data also indicated that there was a reduction in drug usage by regular users for selected drugs.
