Immediate impact of thirty-two drug use prevention activities among students at continuation high schools

Those teenagers who are unable to remain in the regular school system for reasons including substance use are transferred to a continuation high school. Generic comprehensive social-influence-drug-use-prevention-activities are less likely to be effective for use with these at risk youth. Thus, both classroom and self-instruction (main mode of instruction at continuation high schools) versions of 16 activities derived from different theoretical sources were tested and ranked on immediate outcome variables. 388 students from six continuation high schools were provided with a pretest-activity-posttest "component study" protocol. The scores on perceived quality ratings were standardized and averaged to permit easy comparisons across lessons. While yielding similar knowledge changes, students who received the health educator led activity consistently reported higher scores on perceived quality. Social influence-oriented lessons, in general, were rated of relatively low perceived quality. The present approach assisted in selection of the lessons with the greatest overall immediate impact.
