This is Part I of a final evaluation of a program designed to reduce the incidence of destructive risk-taking behavior (e.g. drug-alcohol abuse, and juvenile delinquency) among school-age youth. Background research indicates that peer group pressure is the single most important factor in dictating the presence or absence of juvenile delinquency behavior. The Peer Dynamics program trains and supervises students who participate in a group interaction plan with other students to develop self-esteem and better communication skills; peer modeling takes place. Some past discrepancies in figures reported by schools previously involved are discussed; currently, distinctions are made between the schools with active programs, schools with inactive programs, and programs deleted due to staff turnover. Timetables are provided for school years 1979-1981, and several changes are suggested in the areas of organization, distribution of activities, newsletters and in staff training. Limiting the program to junior high school grades is suggested because that age group appears to benefit most from the program. New evaluation tools have been selected because the earlier tests were seen as non-functional on several levels. On-site visits are recommended in the future only for schools implementing a program for two years, with regional follow-ups. Appendices are included. (Author/KMF)
