Quality of Life in Alcohol Use Disorder: Exploration of Predictive Factors in a Cross-Sectional Study

Alcohol use disorder (AUD) is a chronic and relapsing biopsychosocial condition that leads to various medical, psychological, social, economic, and personal issues. This study evaluated how sociodemographic characteristics, clinical variables, impulsivity dimensions, and cognitive functions were associated with quality of life (QoL) among patients seeking treatment for AUD. Furthermore, the study investigated the predictors of QoL among patients seeking treatment for AUD based on attention, cognitive instability, motor impulsiveness, perseverance, and self-control dimensions of trait impulsivity. This study also investigated the potential mediating effect of anxiety and alcohol use severity in this relationship. After an initial assessment, the participants underwent comprehensive evaluations, including sociodemographic data, clinical history, and QoL domains. The evaluations also covered AUD severity, impulsivity dimensions, cognitive functions, craving intensity, depression, anxiety, and self-efficacy. Multiple linear regression analyses were employed to identify associations between independent variables and QoL. The attention dimension of impulsivity and anxiety symptoms significantly predicted physical health domain of QoL. The self-control dimension and severity of alcohol use disorder predicted psychological domain of QoL. The indirect effect of attention dimension on physical health was significant [effect = -1.082, 95% CI (-2.008, -0.3598)]. The significance of impulsivity in influencing QoL for individuals with AUD has profound clinical implications. These findings underscore the importance of addressing anxiety and impulsivity in managing AUD, given their considerable impact, particularly on QoL, ultimately shaping treatment outcomes.
