Abstract

The purpose of this study was to investigate the effect size of non-pharmacological intervention applied to patients with anxiety disorder and to provide information about evidence-based intervention. Twenty three studies were selected for meta-analysis through a systematic review of domestic studies. We searched journal articles published in Korea up to May, 2015 using the key words "Anxiety Disorders (MeSH)" and "Treatment or Intervention". Meta-analysis was performed using a random effects model, and the effect sizes on each of anxiety and depression were calculated. The effect size for anxiety of non-pharmacological intervention in this study was Hedges' g=1.693 (95% CI; 1.267-2.120), indicating a large effect size. The effect size for depression was Hedges's g=1.571 (95% CI; 0.481-2.661), indicating a large effect size. It is significant that this study systematically synthesized the study results for non-pharmacological intervention effects applied to patients with anxiety disorders in Korea. It also established a basis that can be applied to nursing intervention.

본 연구는 메타분석을 통해 불안장애에 적용된 비약물적 중재요법의 효과크기를 알아보고 대상자 중재에 근거기반한 객관적 자료를 제공하기 위해 수행되었다. 이를 위해 국내 주요 DB를 이용하여 불안장애에 대하여 비약물적 중재를 제공한 2,690편의 논문 중 불안과 우울을 종속변수로 하여, 선정기준에 적합한 최종 23편의 논문을 대상으로 분석을 실시하였다. 검색어는 '불안장애(anxiety disorder)', 중재(treatment or intervention)'를 이용하여 2015년 5월까지 출판된 논문을 검색하였다. 분석은 랜덤 효과모형을 이용하였으며, 불안과 우울의 효과크기를 각각 산출하였다. 본 연구에서 비약물적 중재의 불안에 대한 효과크기는 Hedges's g=1.693, 우울에 대한 효과크기는 Hedge's g=1.571로 큰 효과크기를 보였다. 본 연구는 국내에서 시행되고 있는 불안장애에 적용한 비약물적 중재효과에 대한 연구결과를 체계적으로 종합하고, 그 효과크기를 객관적으로 제시하여 간호중재에 적용할 수 있는 근거를 마련하였다는데 그 의의가 있다.
