A Pilot Randomized Controlled Trial (RCT) of Acceptance and Commitment Therapy Versus Cognitive Behavioral Therapy for Chronic Insomnia
Abstract
OBJECTIVE: To compare the effectiveness of protocols for acceptance and commitment therapy for insomnia (ACT-I) and cognitive behavioral therapy for insomnia (CBT-I) in adults. METHOD: = 10.7) with chronic insomnia who were randomized to 6 weekly group sessions consisting of ACT-I (n = 19) or CBT-I (n = 18). The primary outcome measures were based on the Insomnia Severity Index (ISI) total score, a measure of insomnia complaints, and included the proportions of treatment responders (defined as a change in score of 8 points or more) and remitters (defined as a final score below 8). RESULTS: Both treatment modalities significantly reduced insomnia severity. Post-treatment, the proportion of treatment responders was higher in the CBT-I than the ACT-I (64.7% vs. 50.0%, respectively) group and six months later, ACT-I made further improvements whereas CBT-I had a reduced treatment response (58.8% vs. 55.6%, respectively). CBT-I was associated with a higher proportion of insomnia remission at post treatment. CONCLUSIONS: Both CBT-I and ACT-I are effective, with a higher proportion of insomnia remitters in CBT-I post-treatment. The different change trajectories for the two therapy groups provide insights into behavioral change via a cognitive versus contextual approach.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
