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.
