Aim Impulsivity has been identified as a key relapse risk factor in patients with alcohol use disorder (AUD); however, the inherent characteristics of this relationship have been largely understudied. The heterogeneity of AUD and variation in impulsivity constructs require careful consideration to inform future work examining the relationship. This study sought to review empirical findings examining facets of impulsivity and AUD relapse. Methods A systematic search strategy was employed to capture studies on impulsivity measures related to AUD relapse. Impulsivity measures were qualitatively organized in terms of ‘trait impulsivity’—typically measured by self-report questionnaires—and ‘behavioural impulsivity’, i.e. ‘motor impulsivity’, ‘impulsive choice’ and ‘reflection impulsivity, assessed with cognitive–behavioural tasks. Results Seventeen peer-reviewed papers were identified. Relapse outcomes varied substantially in relation to impulsivity measures. Twelve papers included aspects of ‘trait impulsivity’, and nine studies included ‘behavioural impulsivity’ measures, from which five studies dealt with the ‘impulsive choice’ subcategory. The Barratt Impulsivity Scale was the self-report questionnaire that was most frequently used. Conclusions All three included facets of impulsivity (‘trait-, motor- and impulsive choice impulsivity’) were associated with AUD relapse, but none seemed to be superior to another. This study confirmed that research on the relation between impulsivity and AUD relapse is relatively scarce. Future research and treatment options are proposed.

For decades predictors of alcohol use disorder (AUD) relapse have been studied, and around 40 different clinical and demographic relapse determinants have been identified. This paper aims to investigate the relationship of two of these AUD relapse factors, namely craving and meaning in life (MiL). We hypothesized that greater meaning in life would be associated with lower cravings and lower relapse rates. An AUD subsample of 81 patients within a clinical population that participated in ongoing exploratory research on religious/spiritual factors related to substance use disorders was followed up to 1 year. Craving (as measured with the Penn Alcohol Craving Scale) and meaning in life (as measured with the Meaning in Life Questionnaire-presence subscale) measures were assessed at baseline and relapse was assessed at 6-and 12-month follow up. Main effects and the interaction between craving and meaning in life in predicting alcohol relapse (with relapse defined as 'any alcohol use' and ! 3 consecutive days of drinking) were calculated/subject of analyses. We also investigated the relationship between relapse and alcohol dependence severity as measured with the Leeds Dependence Questionnaire. Baseline craving and dependence severity were related to relapse, but there were no associations between meaning in life and levels of craving or alcohol relapse. Our findings suggest a need for additional research on characterizing the Meaning in Life concept.
