Quality of life (QoL) was a important factor of treatment outcome in alcoholics. This study was to examine the relationship between family support and quality of life among alcoholics, to explore the moderating effect of abstinence self-efficacy on those relationship and to suggest practical implications for intervention services.

 Methods

Data for this study were collected through the use of a survey instrument completed by 771 alcohol dependent admitted to inpatient treatment from 20 psychiatric hospital. Subjects were screened using the Family support, Drug Taking Confidence Questionnaire-8, World Health Organization Quality of Life Assessment Instrument. Collected data were analysed by moderated multiple regression and simple slope analysis.

 Results

Family support was directly associated with QoL. Also the abstinence self-efficacy had moderating effects on relationship between family support and QoL. Simple slope analysis showed that the effects of family support on QoL were significant at low and high levels of abstinence self-efficacy and especially the effects of family support on QoL were more higher at the high levels of abstinence self-efficacy.

 Conclusion

This findings suggest that abstinence self-efficacy is an important factor to QoL among alcohol dependents. Increasing self-efficacy, family support will be improve the QoL and recovering process. Based on these findings suggest practical intervention.
