Socioeconomic resources and quality of life in alcohol use disorder patients: the mediating effects of social support and depression

Background Quality of life (QoL) has recently attracted increased attention as a major indicator of the recovery from alcohol use disorder (AUD). This study investigated the mediating effects of social support and depression for the relationship between socioeconomic resources and QoL among people with AUD in South Korea. Methods Patients across South Korea who had been diagnosed with AUD in the previous year (n = 404) and were registered at hospitals and addiction management centers were surveyed. The participants ranged in age from 19 to 65 years. Structural equation modeling was performed, using stable residence, income, stable employment, social support, depression, and QoL as predictors. Bootstrapping analysis was performed to test for mediating effects. Results The socioeconomic resources income (beta = .297, p < .001), stable employment (beta = .131, p < .01), and stable residence (beta = .091, p < .05) showed statistically significant and positive relationships with social support. However, none of these were significantly related to depression. Social support showed a significant and negative relationship with depression (beta = -.172, p < .001). Income positively and directly influenced QoL (beta = .148, p < .001). All three socioeconomic resources indirectly influenced depression through social support, which, in turn, influenced QoL. This suggests that socioeconomic resources directly influence QoL and indirectly influence it through social support. Conclusion These findings suggest that social support has an important role in improving the QoL of people with AUD. Furthermore, socioeconomic resources, such as having a stable residence, employment, and income, are necessary for recovery from alcohol addiction.
