Resumen:
Background: The Marijuana Consequences Questionnaire [MACQ] assesses marijuana-related problems. This 8-factor (50-items) measure covers a broad array of multiple dimensions encompassing 50 negative consequences of gradient severity that are particularly relevant in the context of college. The present study aimed to validate the Spanish version of the 50-item Marijuana Consequences Questionnaire (S-MACQ) by analyzing the psychometric properties of internal, convergent, and concurrent validity and estimating internal consistency. We also examined the correlation between the brief (SB-MACQ) and the full S-MACQ and whether they similarly correlate with marijuana outcomes and marijuana-related variables. Method: College students from the two largest public universities of Cordoba city (Argentina) completed an online survey as part of a broader study focused on marijuana use and risky sexual behaviors. Only data from students that reported last-year marijuana use (n=470; 70.6% women; Mean age 22.67±3.52 years; 45.7% enrolled in psychology) were included in the study. We conducted independent samples t-tests to evaluate differences in the number of negative consequences (for the total scale and for each S-MACQ dimension) as a function of biological sex or frequency of use. Confirmatory factor analyses (CFA) was conducted to examine the factor structure of the S-MACQ. We conducted Pearson correlation analyses to examine the association between the number of marijuana-related consequences as measured by the S-MACQ and scores (a) in the CUDIT, a standardized measure of marijuana-related problems (i.e., convergent validity), (b) frequency and quantity of marijuana use (i.e., concurrent validity), (c) motives for marijuana use (i.e., concurrent validity). We examined the Pearson correlation between the SB-MACQ and the S-MACQ and then we estimated the difference between the Pearson correlation of the SB-MACQ and the S-MACQ with all the marijuana outcomes and marijuana-related variables. Results: Results from the CFA supported an 8-factor structure. The scores of the S-MACQ showed appropriate internal, concurrent and convergent validity, alongside with adequate internal consistency. The S-MACQ was largely correlated with the SB-MACQ and the correlations between these two versions and marijuana outcomes/marijuana-related variables did not significantly differ. Discussion: Findings supported the S-MACQ as a valid measure to assess marijuana-related problems in Spanish-speaking students. The instrument can be used to identify a broad diversity of marijuana problems in this population.
