A lack of adequate substance abuse information at an elementary school prompted this practicum examining at risk students. Classroom guidance lessons on substance abuse prevention were given, which included small group counseling sessions regarding self-esteem and problem-solving skills, followed by posttests. Classroom guidance lessons revealed a need for prevention programs which imparted knowledge about the use and consequences of alcohol and substances. The self-esteem small group sessions showed that students responded positively to assertiveness training and social skill enhancement. Students also benefitted from talks about responsibility, self-discipline and good judgment. Participants indicated a need for all students to join in drug awareness and a desire for more small group counseling sessions and classroom guidance lessons regarding the issues of substance abuse prevention. Parents reported that they felt excluded from their children's substance abuse programs. It was concluded that comprehensive school substance abuse prevention programs should include lessons for students regarding feelings, pharmacology, and self-awareness, as well as involve parents. Students who completed posttests on substance abuse prevention, self-esteem, and problem-solving skills performed perfectly. Contains 18 references. (Three appendices list all three posttests.) (RJM)
