Executive functions and addictions: a Structural Equation Modeling Approach and the Italian validation of the Adult Executive Functioning Inventory (ADEXI)

Le résumé fourni par la source

INTRODUCTION: the work aims to observe the associations between psychoactive substance use and gambling and executive functioning as well as to validate the Italian version of the "Adult Executive Functioning Inventory" (ADEXI) scale. METHODS: ). Structural Equation Modeling (SEM) was performed to explore the associations between ADEXI and other behaviors measured with standardized questionnaires. Cronbach α has been performed to investigate the psychometric properties of the Italian version of the ADEXI scale. RESULTS: SEM showed that both WM and INH were correlated with problematic cannabis use (WM r = 0.112; INH r = 0.251) and gambling (WM r = 0.101; INH r = 0.168), while problematic alcohol use was correlated only with INH (r = 0.233). Cronbach α for the WM subscale was 0.833 (CI 0.826-0.840), while for INH was 0.694 (CI 0.680-0.708). CONCLUSION: results pointed out a strong correlation between addictions (substance-related and non-substance-related) and WM and INH impairments among the adult general population. Moreover, the ADEXI scale could be considered a valuable tool for general population surveys to detect working memory and inhibition characteristics.
