title: A pilot study of cognitive-behavioral therapy of insomnia in people with mild depression.
abstract: In some cases, insomnia and depression may have a reciprocal relationship, in which each aggravates and maintains the other. To test the hypothesis that reduction of insomnia would result in reduction of depression in patients (N=10) with both disorders, a repeated-measures design was used comparing depression and insomnia levels before and after 6 sessions of cognitive-behavioral therapy of insomnia. Posttreatment, 100% of completers (n=8) had a normalized sleeping pattern, and 87.5% had normalized depression scores. Significant posttreatment improvement was seen in sleep onset latency (-31 min), wake time after sleep onset (-24 min), total sleep time (+65 min), sleep efficiency (+14%), and sleep quality (+19%), which was maintained at 3-month follow-up. A decreasing trend occurred in depression scores from pre- to posttreatment, which reached significance at 3-month follow-up. Intent-to-treat analyses showed similar results.
