A systematic review of the reasons for quitting and/or reducing alcohol among those who have received alcohol use disorder treatment.

Research has primarily studied reasons for quitting and/or reducing alcohol use in non-treatment samples. This systematic review aimed to characterize the reasons for quitting and/or reducing alcohol use among those who have received treatment for AUD and examine how reasons endorsed differ across measurement methods used. Articles were identified through PsycINFO, Web of Science, PubMed, and CINAHL. Twenty-one articles met inclusion criteria. Thematic coding revealed 21 unique themes in reasons for quitting and/or reducing. Common reasons included physical health issues, misalignment with personal goals, family influence, and social factors-also noted in non-treatment populations. Unique themes like hitting rock bottom and avoiding disapproval were identified, potentially linked to treatment initiation or development. The measurement approach influenced the reasons reported, highlighting the need for standardized methods. Common reasons are fundamental and are not a result of treatment, while others are unique to individuals who have received AUD treatment, which may suggest that they are critical in leading one to seek treatment or may be developed during treatment. Assessing and tailoring treatment based on these reasons may enhance outcomes. Standardizing how we measure reasons for quitting or reducing alcohol is crucial for comparing studies and improving treatment. Future research should evaluate reasons over time, assess their importance at different treatment stages, and use varied assessment strategies for comprehensive insights.
