Self-Reported Reasons for Abstinence from Illicit Drugs.

These salient reasons are consistent with outcome expectancy and social learning models that have been proposed to explain drug initiation. To enhance the value of future research, we recommend testing whether importance ratings differ across contexts; repeatedly assessing within-subject variability of reasons across time; evaluating the association of psychological characteristics with reasons for abstaining; and continuing to evaluate which reasons for abstaining vary by type of drug, gender, ethnicity, and religiosity. We also recommend additional research comparing which reasons predict continued abstinence and which predict initiation of use during follow-up.
