Effect of Intervention on Alcohol, Smoking, and Substance Involvement Screening Test Scores

Specific substance ASSIST scores at follow-up relative to baseline in college students. The data are expressed as mean ± standard error of the involvement scores in the three groups: ASSIST/MBIc, ASSIST/MBIi, and control. From the left to right the bars represent total involvement score, alcohol, tobacco, marijuana, and summation of the scores for other drugs. The symbol “*” represents a significant difference (P ≤ .05, ANOVA followed by Newman–Keuls test) compared with control.
