Purpose: The aim of the study was to investigate associations of spiritual well-being, attitude toward death, and quality of life among Alcoholics Anonymous (AA). Methods: This study was cross-sectional and descriptive in design. The data was collected from August to September 2018 with 133 AA members drawn from two provinces of South Korea. The data were analyzed using descriptive statistics, independent t-tests, one-way ANOVA with Turkey tests, Pearson's correlation coefficients, and hierarchical multiple linear regression analyses using SPSS/WIN 20.0 program. Results: The existential spiritual well-being (β=.52, p<.001), attitude toward death (β=.24, p<.001), dual diagnosis (β=-.17, p=.003), occupation (β=.12, p=.035) of the participants were significant factors, which explained 63.7% of the variance of quality of life. Conclusion: The study findings highlight the need to develop psychological nursing strategies to enhance the spiritual well-being and improve a positive attitude toward death based on the job and dual diagnosis among AA members to improve their better quality of life.
