Role rehearsal and efficacy: two 15-month evaluations of a ninth-grade alcohol education program.

A ninth-grade alcohol education program aimed at reducing drinking, drinking and driving, and riding with a drinking driver was developed on the basis of problem behavior theory, social cognitive theory and role theory. In Year 1 the program was taught by Social Studies teachers to half of the eighty-four ninth-grade classes in all nine junior high schools in a single school system; the other half served as controls. In Year 2 the program was taught to the ninth-grade students of the same school system by English teachers. Students' knowledge, skills and practices were measured before and four-six weeks and one year after the program. Results indicated significant increases in knowledge and perceived ability to resist pressures to drink among experimental students. No significant differences were noted for the drinking or the drinking and driving practices of either group. One year after the program, significantly fewer students in the experimental classes reported riding with a driver who had been drinking. Results suggested that English teachers were more effective than Social Studies teachers in teaching this program.
