Early Prediction of Initiation of Abstinence From Cocaine

The authors administered a five‐item craving questionnaire daily to 86 outpatients to determine whether initial craving scores predicted the likelihood of initiation of abstinence within a 30‐day period. Patients with higher mean craving scores during the first 3 days of the study were less likely to initiate abstinence. However the relationship between craving and abstinence initiation was not linear. Rather, patients in the top quartile of craving scores were significantly less likely to abstain than were patients in the lower three quartiles. The findings suggest that this rapid, easily administered craving questionnaire may have short‐term predictive validity.
