Examining the psychometric properties of the Multidimensional Experiential (MEAQ) Questionnaire in combustible cigarette smokers

The aim of the study was to validate the 30-item version of the Multidimensional Experiential Avoidance Questionnaire (MEAQ-30) in a sample of individuals who smoke combustible cigarettes and to examine the relationship between nicotine dependence, cigarette smoking, and experiential avoidance. Confirmatory factor analysis (CFA) was used to verify the structure of the MEAQ-30 and to test measurement invariance in a general population sample (<i>n</i> = 1040) and a sample of individuals who smoke combustible cigarettes (<i>n</i> = 550). Correlation and regression analyses were performed in a sample of individuals who smoke combustible cigarettes (<i>n</i> = 242) to evaluate the stability, dependability, convergent validity, discriminant validity, predictive validity and incremental predictive validity of the measure. The MEAQ-30 demonstrated adequate model fit and met criteria for measurement invariance. It exhibited good internal consistency, good stability, good discriminant validity, weak incremental predictive validity, and lower than expected levels of dependability. Based on our findings, the MEAQ-30 appears to be a valid measure of experiential avoidance in individuals who smoke combustible cigarettes.
