A placebo-controlled test of cognitive-behavioral therapy for comorbid insomnia in older adults.

The present study tested cognitive-behavioral therapy (CBT) for insomnia in older adults with osteoarthritis, coronary artery disease, or pulmonary disease. Ninety-two participants (mean age = 69 years) were randomly assigned to classroom CBT or stress management and wellness (SMW) training, which served as a placebo condition. Compared with SMW, CBT participants had larger improvements on 8 out of 10 self-report measures of sleep. The type of chronic disease had no impact on these outcomes. The hypothesis that CBT would improve daytime functioning more than SMW was only supported by a global rating measure. These results add to findings that challenge the dichotomy between primary and secondary insomnia and suggest that psychological factors are likely involved in insomnias that are presumed to be secondary to medical conditions.

Home-based video CBT for comorbid geriatric insomnia: a pilot study using secondary data analyses.

Two recent studies showed that cognitive-behavioral treatment (CBT) is efficacious in treating insomnia in older adults with comorbid medical conditions. The authors extended these findings by comparing 12 older adults with comorbid insomnia who received a home-based video CBT program to the authors' previously published data on 24 participants who received classroom CBT or no treatment. All 36 participants were initially randomized within the same protocol, but the video arm was conducted 7 months after completion of the other two study arms. Compared to controls, the video CBT group demonstrated significant changes in five of eight self-report measures of sleep at posttreatment, including sleep latency, time awake after sleep onset, total time in bed, overall sleep quality, and dysfunctional beliefs and attitudes about sleep. Compared to controls, the video CBT group also had posttreatment improvements in daytime functioning, including mood, pain perception, social functioning, and energy-vitality. Although video CBT was not significantly different from classroom CBT on self-report measures, the attrition rate was higher (27% vs. 19%) and the number of participants who achieved clinically significant change was lower (50% vs. 73%). These preliminary findings suggest that delivering CBT in a home-based video format has the potential to serve as a first-line, cost-effective treatment for comorbid insomnia.

Efficacy of two behavioral treatment programs for comorbid geriatric insomnia.

Older adults with comorbid insomnia and medical illness have been excluded from behavioral treatment research, but recent evidence suggested that such treatments would be effective with this population. In this study, 38 older adults with comorbid insomnia were randomized to 1 of 3 conditions: classroom cognitive-behavioral treatment (CBT), home-based audio relaxation treatment (HART), or delayed-treatment control. Compared to the control group, the CBT group had significant changes in 5 of 7 self-report measures of sleep at the 4-month follow-up. The HART group obtained significant outcomes on 3 of 7 measures. Wrist actigraphy measures and secondary-outcome measures did not yield significant findings for either treatment. Clinically significant changes at follow-up were obtained for 54% of patients in CBT, 35% in HART, and 6% in the control group when treatment dropouts were included. Although not as effective as in-person CBT, home interventions may have utility as a first-line, low-cost treatment.
