Initial validation of the Voris Cocaine Craving Scale: a preliminary report.

Although cocaine craving can persist for weeks after the last use and is thought to play a role in future relapses, few short, reliable, and valid instruments exist to measure craving. Therefore, we wished to examine the validity of the 4-item Voris Cocaine Craving Scale (VCCS), which was previously found reliable. A consecutive series of 41 recently withdrawn cocaine-dependent patients completed the 4-item VCCS and the Cocaine Craving Questionnaire (CCQ), which was used as the criterion measure. The VCCS items 1 "craving," 2 "mood," and 3 "health" were significant and highly correlated with the CCQ total craving score. The VCCS may prove to be useful in future outcome studies involving cocaine craving and in routine clinical treatment.
