This study presents a comprehensive evaluation of the prevalence of Alcohol Use Disorder (AUD) and relapse risk factors in Kermanshah Province, Iran, using a combination of direct and indirect methods, including the Network Scale-Up (NUS) and Crosswise (CM) models, along with tree-based analysis.

The findings reveal varying estimates of AUD prevalence and identify significant factors influencing relapse, such as family history of physical illness. These insights can guide healthcare interventions aimed at preventing AUD and enhancing relapse management in the region. (SAV)
