Abstract

The purpose of this study is to identify the effects of laughter therapy on healthy life of human through meta-analysis of literature. Based on domestic and foreign academic databases, 495 foreign and 199 domestic literature were reviewed focusing on "quality of life," as the ultimate goal of health. The final seven literature were extracted. Analyses was performed in R version 3.5.1. Significant differences (SMD=0.23, p<0.01) were shown in the pre-post comparisons of experimental groups using the mean difference (effects size) analysis of the extracted samples. Significant results were not shown in meta regression analyses setting explanatory variables as 'treatment sessions and durations' and outcome variables as 'treatment effects of laughter therapy'. This study is meaningful in comparative analyses of pre-post experimental groups to establish 'laughter therapy' has a significant effect on improving 'quality of life' and is a useful intervention method, especially for older people, and older women with depression.

본 연구의 목적은 문헌의 메타분석을 통해 웃음요법이 인간의 건강한 삶에 미치는 효과를 규명하는데 있다. 국내 외 학술데이터베이스를 토대로 건강의 궁극적인 목적인 "삶의 질"을 중심으로 국외 495편, 국내 199편의 문헌을 검토하였다. 최종 7편의 문헌이 추출되어, 분석은 R version 3.5.1로 수행하였다. 추출된 표본의 평균차이(효과크기)분석을 활용하여 실험군의 사전 사후 비교에서 유의미한 차이(SMD=0.23, p<0.01)를 보였으나, '웃음요법의 처치회기와 기간'을 설명변수로, '웃음요법의 처치효과'를 결과변수로 설정한 메타회귀분석은 유의미한 결과를 보이지 않았다. 본 연구는 실험군의 사전 사후 비교분석에서 '웃음요법'이 '삶의 질 향상'에 유의미한 효과를 지니고 있고, 특히 노인, 우울증을 앓고 있는 중년 이상의 여성에게 유용한 중재기법임을 규명하였다는 데 그 의의가 있다.
