This study sought to find patterns among the relationship of the factors of substance abuse, home environment, employment during the school year, participation in school activities, and participation in activities outside of school and to confirm or deny that the patterns established for data collected and analyzed during the 1990-91 year would be reflected in the analysis of a different data set collected during the 1991-92 school year. The 1990-91 data set included the usable responses of 7,279 middle and senior high students and the 1991-92 data set included the usable response of 5,541 middle and senior high school students. The instrument utilized contained 52 items with multiple choices for each item. The use of substances surveyed included tobacco, alcohol, marijuana, and cocaine. Employment included weekend and after school jobs held during the school year. The home situation was classified as one with both parents present, a parent/step-parent environment, or a single parent or other home environment. The results of the study indicated that the students who are at risk for substance abuse have the following characteristics: (1) the student is employed during the academic year; (2) the student comes from a home environment where both parents are not present; and (3) the student is not participating in school activities.
