Résumé :
Given that marijuana remains the most commonly used illicit substance, identification of the role of potentially malleable cognitive factors in marijuana-related behaviors remains an important goal. The Marijuana Effect Expectancies Questionnaire (MEEQ; Schafer & Brown, 1991) assesses marijuana effect expectancies that are differentially related to marijuana use and use-related problems. Evaluation of the desirability of marijuana effect expectancies may provide additional information regarding cognitions related to marijuana use behaviors. The present study examined the psychometric properties of the Marijuana Effect Expectancy Questionnaire - Valuations Scale (MEEQ-V) which was developed for this study to assess the desirability of marijuana effect expectancies. The sample was comprised of 925 (73.0% female) undergraduate participants, 41.9% of whom endorsed lifetime marijuana use and 24.7% of whom reported current (past three-month) use. The MEEQ-V scales demonstrated adequate internal consistency. Most (but not all) MEEQ-V scales were correlated with their corresponding MEEQ scale. There was some support for convergent validity. MEEQ-V scales were differentially related to frequency of marijuana use and use-related problems. Most MEEQ-V scales were related to frequency of marijuana use above and beyond variance attributable to corresponding MEEQ scales. Results suggest that assessment of desirability of marijuana's effects could provide unique and important information about cognitions related to marijuana use behaviors.
HIGHLIGHTS:
• The MEEQ-V assesses desirability of marijuana effect expectancies.
• MEEQ-V scales had adequate internal consistency and convergent validity.
• Most MEEQ-V scales were correlated with their corresponding MEEQ scale.
• MEEQ-V scales were differentially related to marijuana use and use-related problems.
• Most MEEQ-V scales were related to use after controlling for MEEQ scale.
HIGHLIGHTS:
• The MEEQ-V assesses desirability of marijuana effect expectancies.
• MEEQ-V scales had adequate internal consistency and convergent validity.
• Most MEEQ-V scales were correlated with their corresponding MEEQ scale.
• MEEQ-V scales were differentially related to marijuana use and use-related problems.
• Most MEEQ-V scales were related to use after controlling for MEEQ scale.
