This randomized controlled trial investigated predictors of success in Cognitive Behavioral Therapy for Insomnia (CBT-I) among 96 older adults with insomnia. Results showed significant reductions in insomnia severity, with Insomnia Severity Index (ISI) scores decreasing after six weeks (Z = 8.3, p < .001) and remaining improved at 12 months (Z = 8, p < .001).
Key findings
- ISI scores decreased significantly after six weeks of CBT-I (Z = 8.3, p < .001).
- ISI scores remained significantly improved at the 12-month follow-up (Z = 8, p < .001).
- Higher baseline sleep self-efficacy was associated with lower ISI scores immediately after CBT-I (β = -0.03, p < .02).
- Lower depression severity was linked to lower ISI scores immediately after CBT-I (β = 0.06, p = .04).
Why it matters
Understanding predictors of CBT-I success can help clinicians tailor treatment plans for older adults with insomnia, potentially improving outcomes and ensuring more effective use of non-pharmacological interventions.
