Project DARE (Drug Abuse Resistance Education) is the most prevalent s
chool-based drug-use prevention program in the United States, but ther
e is little evidence of its effectiveness. Results from a longitudinal
evaluation of the program in 36 schools in Illinois provide only limi
ted support for DARE's impact on student's drug use immediately follow
ing the intervention, and no support for either continued or emerging
impact on drug use 1 or 2 years after receiving DARE instruction. In a
ddition, DARE had only limited positive effects on psychological varia
bles (i.e., self-esteem) and no effect on social variables (e.g., peer
resistance skills). Possible substantive and methodological explanati
ons for the relative lack of DARE's effectiveness observed in this stu
dy are discussed.
