A replication study of e-mail-based cognitive-behavioral therapy for insomnia
Abstract
본 연구에서는 이메일 기반의 불면증을 위한 인지행동치료(email-based
cognitive-behavior therapy for insomnia) 프로그램의 효과성을 국내에서
반복검증 하고자 하였다. 또한, 프로그램의 효과에 영향을 주는 요인으로
수면에 대한 역기능적 신념을 제시하여 이를 탐색하였다. 본 연구에서 사용된
프로그램은 불면증을 위한 인지행동치료를 근거로 한 자조 프로그램으로,
미국 스탠포드 대학에서 개발되었다. 프로그램 참여를 위해 불면증을
경험하고 있는 만 18세 이상~만 30세 이하의 대학생 39명에게 매주 1회
치료 프로그램 자료를 총 8주 동안 이메일로 발송하였다. 이메일 기반의
불면증을 위한 인지행동치료를 시행하였으며, 프로그램의 효과성을 확인하기
위해 사전과 사후에 불면증 심각도 척도, 우울, 불안 및 스트레스 척도,
수면에 대한 역기능적 신념 및 태도 척도에 응답하도록 하였다. 또한, 연구
참여 기간 동안 매일 수면일지를 기록하도록 하였다.
본 연구의 결과는 다음과 같다. 첫째, 이메일 기반의 불면증을 위한
인지행동치료를 실시한 결과 수면 효율성(p <.001)과 총 수면시간 및 기상
후 상쾌함(p <.05)에서 유의한 증가가 확인되었다. 입면 후 기상 횟수 역시
유의하게 감소하였다(p <.001). 둘째, 본 프로그램이 불면증 심각도와 우울,
불안 및 스트레스를 유의하게 감소시키고, 수면에 대한 역기능적 신념을
유의하게 수정함을 확인하였다(p <.001). 긍정적인 수면위생 행동 점수의
유의한 증가 역시 관찰되었다(p <.01). 셋째, 사전에 응답한 수면에 대한
역기능적 신념 및 태도가 치료효과를 예측하는지 검증하기 위해 중위값을
기준으로 집단을 구분하였다. 이에 수면에 대한 역기능적 신념 및 태도가
기상 후 상쾌감의 개선 효과를 유의하게 예측함을 확인하였다. 하지만 불면증
심각도 및 수면의 질과 효율성 같은 수면 지표 및 임상 지표의 변화를
예측하지 못하였다.
본 연구는 이메일 기반의 불면증을 위한 인지행동치료 프로그램의
효과성을 반복검증하여 프로그램이 불면증에 효과적인 치료임을 시사하였다.
또한, 다양한 이유로 불면증에 대한 심리적 개입을 받지 못하는 개인에게
폭넓은 치료의 기회를 선택할 수 있도록 하였다. 더불어, 수면에 대한
역기능적 신념 및 태도가 치료효과에 미친 영향을 탐색하였다. 이러한 연구의
결과를 종합하여 본 연구의 의의와 제한점 및 후속 연구의 필요성에 대해
논의하였다.|This study is aimed to (1) replicate the effects of an email
based Cognitive-behavioral therapy for insomnia program, (2)
investigate dysfunctional beliefs and attitudes about sleep as a
predictor that can affect treatment outcome. The program,
Refresh, was based on self-help Cognitive-behavioral Therapy
for Insomnia and it was initially developed at Stanford University.
Thirty-nine participants aged from 18 to 30 completed this
program. The program unit was sent to participants once a week
for 8 weeks via email. Subjects completed the following
assessment before and after the program: the Dysfunctional
Beliefs and Attitudes about Sleep 16(DBAS-16), Insomnia
Severity Index (ISI), Depression Anxiety Stress Scale
21(DASS-21), and the Sleep Hygiene Practice Scale (SHPS).
Also, they reported daily sleep diaries.
The results were as follows: First, results indicated that the
program was effective to reduce insomnia symptoms in spite of
running the program to Korean college students. Sleep efficiency
(p <.001), total sleep time, and refreshing sleep (p <.05) were
increased significantly. Also, number of awakening was
significantly decreased (p <.001). Second, Insomnia Severity,
Depression Anxiety Stress, and Dysfunctional Beliefs and
Attitudes about sleep were significantly decreased (p <.001).
Also, maladaptive sleep hygiene was significantly decreased (p
<.01). Third, this study was separated into two groups by
median of dysfunctional beliefs and attitudes about sleep to
investigate dysfunctional beliefs and attitudes about sleep to
predict treatment outcome. The results show that dysfunctional
beliefs and attitudes about sleep predict only refreshing sleep
among clinical and sleep indices.
This replicate study showed that the program was the effective
intervention for insomnia. It suggests that the program could be an
option for people who struggle with insomnia and couldn't have
treatment for diverse reasons. This study also examined effects of
dysfunctional beliefs and attitude on program outcome.
