Purpose: The purpose of this study was to identify the factors affecting social problem-solving ability in alcohol dependent men in outpatient treatment facilities. Methods: Participants were 148 men dependent on alcohol who were outpatients at 5 hospitals for mentally ill patients in G City. Data were collected from May 1 to June 30, 2016 using self-report questionnaires. Abstinence self-efficacy, existential spiritual well-being, alcohol insight, unconditional self-acceptance, and social problem-solving ability were investigated. For data analysis t-test, one-way ANOVA, Pearson correlation coefficients and multiple regression were employed. Results: Mean score for social problem-solving ability was 18.28±5.27. Social problem-solving ability had a positive correlation with abstinence self-efficacy, existential spiritual well-being, and unconditional self-acceptance. Factors affecting social problem-solving ability in these men were unconditional self-acceptance, lack of sleep disorder, existential spiritual well-being, and religiousness. The explanatory power was 57%. Conclusion: In planning an intervention for social problem-solving ability for alcohol dependent men, it is important to employ strategies which provide enhancement of self-acceptance as a healthy countermeasure to the low level of unconditional self-acceptance and to provide educational interventions for physical health or sleep deprivation for the patients with these problems along with low social problem-solving ability.
