ABSTRACT
The purpose of this study was to evaluate a brief version of the Marijuana Effect Expectancy Questionnaire (MEEQ; Schafer & Brown, 1991). The original MEEQ was reduced to 6 items (MEEQ-B). Principal component analysis (PCA) was performed and two factors were identified (positive effects and negative effects) accounting for 52.3% of the variance. Internal consistencies (0.42 to 0.60) were slightly lower than those of the original MEEQ. The negative effect expectancy scale correlated with criterion variables that assess marijuana use (p ≤ .05). This measure is a helpful tool for clinicians to use when assessing youth expectancies. Replication across different samples of adjudicated youth is recommended.
ABSTRACT
The purpose of this study was to evaluate a brief version of the Alcohol Expectancy Questionnaire-Adolescent (AEQ-A; Brown, Christiansen, & Goldman, 1987). The original AEQ-A was reduced to seven items (called the AEQ-AB). Principal Components Analysis (PCA) was performed and two factors emerged (General Positive Effects and Potential Negative Effects) accounting for 46% of the variance. Internal consistencies are comparable to those of the original AEQ-A (0.50). Scales correlate with criterion variables such as average drinks per week and average number of drinks per heavy drinking day (p < 0.05). It is concluded that this questionnaire may be useful to clinicians providing brief assessment and intervention. Cross-validation in other samples and other settings is recommended.
