Predictors of Cognitive Behavioral Therapy for Insomnia in Older Adults

Key Points

This research examines how baseline sleep self-efficacy and depression severity affect outcomes of cognitive behavioral therapy for insomnia in older adults.
Participants underwent six weeks of cognitive behavioral therapy for insomnia (CBT-I).
Baseline assessments included measures of sleep self-efficacy and depression severity.
Outcomes were measured by reductions in insomnia severity after treatment and during follow-up.
Significant reductions in insomnia severity were observed after CBT-I.
Both sleep self-efficacy and depression severity predicted lower insomnia severity post-treatment.
Sleep self-efficacy was the sole predictor of maintaining treatment gains long-term.

Abstract

Six weeks of CBT-I resulted in significant and sustained reductions in insomnia severity in older adults. Baseline sleep self-efficacy and depression severity significantly predicted lower insomnia severity following CBT-I, whereas only sleep self-efficacy predicted the long-term maintenance of treatment gains. These findings underscore the importance of baseline sleep self-efficacy as key predictor for optimizing treatment planning and long-term outcomes.
