Abstract

Objectives Insomnia has widespread negative implications for health and well-being. Online delivery of mindfulness-based therapy for insomnia (MBTI) has not previously been evaluated. This study investigated the feasibility and preliminary efficacy of a digital MBTI program for improving insomnia symptoms. It was hypothesized that a 6-week digital MBTI program would reduce insomnia symptoms and pre-sleep arousal and improve mood, compared to a waitlist control condition.Methods Twenty-seven participants (M = 29.44, SD = 11.97 years) experiencing insomnia symptoms (insomnia severity index [ISI] ≥ 8) were randomized to either a 6-week intervention or waitlist condition. Participants completed the ISI, pre-sleep arousal scale (PSAS), and the positive and negative affect schedule at baseline, mid-, and post-study. Feasibility was assessed across four domains (acceptability, implementation, practicality, and preliminary efficacy) using self-reports, attrition, program completions, and module completions.Results Feasibility data for the intervention indicated that there was 22% attrition, and 79% of the modules were completed. There were significantly greater reductions in the severity of insomnia symptoms (p < .001) and both cognitive (p = .03) and somatic (p = .02) subscales of the PSAS, at post-intervention compared to the waitlist group. There were no significant group differences in mood.Conclusions This study provides preliminary evidence of the feasibility and efficacy of a digital MBTI, which may assist in the broader dissemination of insomnia treatment.Trial RegistrationAustralian and New Zealand Clinical Trials Registry: ACTRN12620000398909.

  • Sleep effort and cognitive arousal are modifiable perpetuating factors that can be influenced by cognitive behavioral therapy and mindfulness-based therapy for insomnia treatments.

    “Additionally, sleep effort and cognitive arousal are modifiable perpetuating factors that can be influenced by cognitive behavioral therapy and mindfulness-based therapy for insomnia treatments [56–60].”

    From Insomnia is more likely to persist than remit after a time of stress and uncertainty: a longitudinal cohort study examining trajectories and predictors of insomnia symptoms (2024) · cites this paper as [58]

    The Discussion (page unavailable) describes arousal as a mechanism maintaining insomnia and reports that digital mindfulness-based therapy reduced cognitive pre-sleep arousal. The paper also describes how cognitive behavioral therapy and mindfulness-based therapy address sleep-related thoughts. It does not establish that sleep effort is a modifiable perpetuating factor or that either treatment changes sleep effort. (LLM, conf=0.86)

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.
