Abstract
Experimental evaluations of substance use prevention programs are hamp ered by high rates of subject attrition. Attrition threatens the inter nal validity of these studies when attrition is greater in one conditi on than another. Statistical tests of the effects of attrition are typ ically lacking. Attrition threatens the external validity of studies b ecause one may not be able to generalize effects of programs to dropou ts who are systematically different from those who remain.
