Primary use / Purpose: 

The Marijuana Effect Expectancy Questionnaire-Brief (MEEQ-B) is a 6-item index that purports to measure adolescents’ marijuana effect expectancy during interventions. The MEEQ-B is a valid assessment tool for interventionists in evaluating youths in incarcerated settings with limited resources.


The Marijuana Effect Expectancy Questionnaire-Brief (MEEQ-B) is an adapted and shortened version of the original Marijuana Effect Expectancy Questionnaire (MEEQ; Schafer & Brown, 1991) that was intended for assessing marijuana expectancies in an adult population. The MEEQ-B was developed to test adolescents on marijuana expectations, and provide a sensitive but briefer tool for use in fast-pased correctional/clinical environments.


Psychometric characteristics of the MEEQ-B are discussed in Torrealday et al. (2008).
