There were no significant differences in treatment response between primary (no medical condition) and comorbid insomnia participants and no significant differences between the two types of self-help according to sleep log measure. These sleep improvements were maintained among 86 treatment completers who participated in 1-year follow-up assessment. Participants were randomly assigned to a book version or an enhanced multimedia version of CBT-I.īoth versions of CBT-I demonstrated efficacy in improving all measures of sleep at posttreatment, using intent-to-treat analyses. Self-help CBT-I has demonstrated efficacy in previous studies, so two treatments were compared rather than employing a no treatment control group. The latter was employed as a comparison group to test the differential efficacy between primary and comorbid insomnia. The present study tested two methods of self-help cognitive-behavioral therapy for insomnia (CBT-I) for 106 older adults (mean age = 68) with osteoarthritis (n = 33) or coronary artery disease (n = 33) or no significant medical condition (n = 40).
