초록
본 연구의 목적은 자가치료용 불면증 인지행동치료(CBTi) 프로그램을 개발하여 그 효과를 검증하는데 있다. 개발한 CBTi는 수면교육, 수면위생, 자극조절, 수면제한, 이완요법, 인지재구성의 6개 요소를 포함하였다. 총 참가자 142명을 모집하여 100명은 처치집단으로 42명은 대기자 통제집단으로 할당하였다, 처치집단 100명 중 프로그램을 마치고 사후평가까지 완료한 사람은 26명으로 완료율은 26%였다. 4개의 측정 도구(불면증 심각도, 과도한 수면 노력, 비합리적 수면 신념, 우울)에서 집단과 처치의 상호작용을 살펴보았다. 분석 결과, 집단과 처치 간상호작용은 통계적으로 유의하게 나타났다. 프로그램을 완료한 참가자들의 경우 불면증 심각도, 과도한 수면 노력, 비합리적 수면 신념, 우울의 개선이 뚜렷한 반면, 대기자 통제집단의 경우 점수 개선은 나타나지 않았다. 연구 결과, 인터넷으로 전달되는 자가치료용 CBTi도 사용자가 성실하게 활용한다면 효과를 낼 수 있음을 확인하였다. 다만, 자가치료용 프로그램의 낮은 치료이행도의 문제도 확인되어 향후 이를 보완할 방안이 필요할 것이다.
Abstract
This study entailed a self-administered Cognitive behavioral Therapy for Insomnia (CBTi), delivered through an internet platform. The CBTi comprised six components: sleep education, sleep hygiene, stimulus control, sleep restriction, relaxation techniques, and cognitive reconstruction. Out of 142 participants, 100 were assigned to the treatment group and 42 to the waitlist control group. However, only 26 out of 100 participants in the treatment group completed the program and post-evaluation, resulting in a completion rate of 26%. The study examined interactions between group and treatment using four measurement tools: insomnia severity, excessive sleep effort, irrational sleep beliefs, and depression. Consequently, the interaction effect was statistically significant. Participants who completed the program exhibited improvements in insomnia severity, excessive sleep effort, irrational sleep beliefs, and depression, whereas the control group did not demonstrate such enhancements. The study findings suggest that self-treatment CBTi delivered online can be effective if participants demonstrate diligence. However, the observed low adherence to the self-treatment program highlights the necessity for future improvements.
