title: Determination of the reliability and validity of the Marijuana Craving Questionnaire using imagery scripts.
abstract: The purpose of this study was to determine the reliability and validity of the Marijuana Craving Questionnaire (MCQ) by using active imagery of auditorily presented scripts. Current marijuana users (n = 48) imagined scripts that varied in amount of descriptors of desire to smoke marijuana, from no-urge to high-urge content. Self-reported marijuana craving significantly increased as a function of script-urge intensity on Factors 1, 3, and 4 of the MCQ. Homogeneity of items comprising each MCQ factor was examined, indicating no significant departures from unidimensionality. These results verify and extend the reliability and validity of the MCQ as a multidimensional measurement of marijuana craving. The data also suggest that drug craving is not an all-or-none phenomenon.
