Right turns only: an evaluation of a video-based, multicultural drug education series for seventh graders.

This study assessed the effectiveness of a video-based, multicultural drug education series for seventh graders. Right Turns Only (RTO) was produced by the Prince George's County Public School System in Maryland and funded by the Center for Substance Abuse Prevention. Knowledge, attitude, and behavioral intentions of 1,036 seventh-grade students who received the RTO curriculum alone or as a supplement to a traditional drug education curriculum (SMART) were measured to test the effects of this video series and its collateral print materials.
