Comparative effectiveness and predictors of cognitive behavioral therapy for insomnia and its components in older adults: main outcomes of a randomized dismantling trial.

ABSTRACT:

Study objectives

To determine the relative effectiveness and predictors of cognitive therapy (CT), behavioral therapy (BT), and cognitive behavioral therapy (CBT) for insomnia in older adults.

Methods

In a registered clinical trial (NCT02117388), 128 older adults with insomnia disorder were randomly assigned to receive CBT, BT, or CT. Insomnia Severity Index (ISI) score was the primary outcome. Sleep diaries, fatigue, beliefs about sleep, cognitive arousal, and stress were secondary outcomes. Split-plot linear mixed models assessed within- and between-subject changes in outcomes among the treatments. As a secondary analysis, we used linear regression to test predictors of insomnia symptoms improvement, including sleep diary measures, cognitive arousal, stress, beliefs about
