Implementing Sleep Interventions for Older Veterans

Detailed Summary

Sleep problems are common among older people, and research suggests that insomnia has negative effects on health and quality of life in older adults. Prior research suggests that insomnia symptoms are even more common among veterans compared to the general population. In addition, people with sleep problems also often have depression and other problems that seem to decrease their quality of life. In this study, we tested two methods of providing behavioral sleep interventions for treating insomnia in older veterans. The long-term objective of this work was to identify ways to improve access to these types of behavioral sleep interventions for older veterans, in order to improve their well-being and quality of life. This project was conducted in outpatient clinics of the VA Greater Los Angeles Healthcare System. Community-dwelling older veterans (aged 60 years and older) with insomnia were identified by a postal survey. Enrolled veterans with insomnia (N=150 total, 50 per group) were randomized to one of three groups: Individual-Cognitive Behavioral Therapy for Insomnia (Individual-CBTI), Group-CBTI or a group-based Sleep Education Control Condition (Control). Measures of sleep, depression and quality of life were performed at baseline (enrollment in the study), after the treatment was completed, and at 6-months and 12-months follow-up after randomization. Main outcome measures included sleep/wake patterns (sleep questionnaires, sleep diary and wrist actigraphy, which is an objective estimate of sleep and wakefulness). We hypothesized that the intervention would improve sleep at six months follow-up. We also expected that these improvements would be maintained at 12-months follow-up.
