Bravo AJ, et al. - In the present study, college student marijuana users in five countries (Argentina, Netherlands, Spain, Uruguay, and US) were examined for measurement invariance of the Brief-Marijuana Consequences Questionnaire (B-MACQ). In addition, if invariance is met, they evaluated how sex and country influence latent mean differences on the B-MACQ and compared the criterion-related validity across different countries and sex. Findings revealed that accurate assessment of marijuana-related negative consequences could be had using the 20-item B-MACQ among these college students. The 20-item B-MACQ had configural and scalar invariance across sex and four countries (the Netherlands being the exception). Compared to US and Argentinian students, Spanish students reported a higher number of consequences when assessing latent mean differences. Marijuana use indicators, descriptive norms, and injunctive norms for best friend mostly had small-to-moderate positive associations with negative marijuana-related consequences when examining criterion-related validity.
