Objective: The purpose of this study was to determine the clinical effectiveness of nonpharmacological treatment programs for alcohol addiction on quality of life, psychosocial functionality, and a reduction of alcohol consumption through a meta-analysis.
Search strategy : Data were collected from online search engines using search words from domestic and foreign article databases, and from a manual search from related journals.
Selection criteria : The study employed Level I Randomized Control Trial (RCT) nonpharmacological treatment programs for alcohol addiction from 1990 to May 2011, and selected articles that utilized standardized assessment instruments to measure the relevant dependent variables.
Data collection and analysis : Two researchers carried out the literature selection independently and reached an agreement through a discussion when in disagreement. The effective size with the standardized mean difference, a heterogeneity test, a sensitivity test, and a publication bias test upon the selected articles was determined using the Comprehensive Meta-Analysis 2.0 program.
Results: There were a total of 6,726 participants in the 9 selected articles. The effective sizes for quality of life, psychosocial functionality, and alcohol consumption were 0.24, 0.35, and 0.31 respectively. The effective size of psychosocial functionality and alcohol consumption was statistically significant (p <.001), which demonstrates a “small effect size”. This result is reliable, as significant statistical heterogeneity and publications bias were not found.
Conclusion: Nonpharmacological treatment programs for alcohol addiction proved to be effective for psychosocial functionality and alcohol consumption. This can be utilized effectively in evidence-based occupational therapy for individuals with alcohol addiction by occupational therapists in the mental health field
