Abstract

A convergence study was conducted to identify effect size, intervention characteristics, and tendency of laughter therapies on depression for Korean older adults. Of the 486 studies searched in 10 databases, 20 studies in the inclusion criteria were selected. The risk of bias was assessed by SIGN's tool, and the data were analyzed using CMA 3.0 software. Overall effect size of laughter therapy on depression of older adults was medium (standardized mean difference [SMD]=-0.57, 95% CI: -0.70~-0.44, p<.001), and heterogeneity was small ($I^2=18%$). Subgroup analysis showed that the effect sizes of institutionalized group, mixed group, 4-6 weeks of duration, and group intervention were higher than the compared groups. Findings of this convergent meta-analysis would be helpful for health professionals to provide more effective laugher therapy sessions. Further replicative studies in long-term care facilities and more randomized controlled trials of laughter therapy are needed.

본 연구는 우리나라 노인을 대상으로 시행된 웃음치료의 융합적 메타분석을 통해, 노인우울 감소 효과크기를 확인하고, 노인의 우울감소를 위한 웃음치료의 중재특성과 경향을 파악하기 위하여 실시된 융합적 연구이다. 10개의 데이터베이스 검색을 통해 확인한 486개 문헌 중 선정기준에 부합하는 20문헌을 최종 선정하였다. SIGN의 도구를 이용하여 문헌의 질평가를 시행하였으며 CMA 3.0을 활용하여 자료를 분석하였다. 노인우울에 대한 웃음치료의 전체효과크기는 중간크기로 나타났으며 (SMD=-0.57, 95% CI: -0.70~-0.44, p<.001), 작은 크기의 이질성을 보였다($I^2=18%$). 하위그룹 분석에서 재가노인, 통합군, 4-6주 중재군, 집단중재군의 효과가 더 컸다. 본 융합연구의 결과를 활용하여 효과적인 웃음치료 프로그램 구성을 도모할 수 있을 것이며, 추후 노인요양시설 노인을 대상으로 한 반복연구와 무작위배정 실험연구가 더 필요하다.
