This report covers the second year (1991-1992) of a 3-year study of substance abuse prevention and intervention programs in New York City public schools, which included a survey of 891 students who received substance abuse intervention services in the schools, plus a field study in 12 sample schools focusing on services that the first year's study had identified as warranting close attention, including peer programs, staff development, and parent involvement. Findings are reported which showed that the largest percentage of students receiving services were in the middle schools, and that these services typically included both individual and group counseling by Substance Abuse Prevention and Intervention Specialists (SAPIS). Other findings are cited in which between 30 and 50% of students reported improvement in such areas as grades, relationships with teachers, and attendance after receiving these services. Chapter I of this report provides an introduction to the background of the project and the current study. Chapter II presents the results of the student survey. Chapter III discusses the SPARK Peer Players' role in the high school substance abuse prevention program. Chapter IV describes staff development offered by SAPIS and parent outreach efforts. Chapter V offers evaluators' conclusions and recommendations based on the data analyzed in this report. (Author/NB)
