Treating Comorbid Insomnia in Transdiagnostic Internet-Delivered Cognitive Behaviour Therapy
September 20, 2022 updated by: University of Regina
Treating Comorbid Insomnia in Patients Receiving Transdiagnostic Internet-Delivered Cognitive Behaviour Therapy for Anxiety and Depression: A Randomized Controlled Trial
Transdiagnostic Internet-delivered Cognitive Behaviour Therapy (ICBT) is an efficacious treatment option for anxiety and depression; however, not all patients benefit equally and some leave treatment before program completion.
Comorbid symptoms of insomnia are extremely common among individuals seeking ICBT, yet sleep problems are rarely a primary focus of treatment in transdiagnostic ICBT despite insomnia being a known risk factor for anxiety and depression.
This trial is designed to test whether an ICBT program for anxiety and depression can be improved by providing therapy for insomnia alongside the standard transdiagnostic program.
For this randomized controlled trial, patients will be randomly assigned to receive either the standard ICBT program for anxiety and depression, which includes only brief supplementary information about sleep (n = 68), or a modified version that includes a lesson specifically on sleep (n = 132).
The sleep lesson will introduce patients to two key behavioural strategies: sleep restriction and stimulus control, which previous research has demonstrated are effective at reducing insomnia.
Patients will monitor their sleep throughout treatment and will complete measures of insomnia, anxiety and depression before treatment, at the end of the 8-week program, and 3 months after program conclusion to allow for a comparison of patient outcomes and completion rates between conditions.
The acceptability of the new intervention will also be assessed by asking participants to provide feedback on the new materials and to complete measures of treatment satisfaction and working alliance.

---|---|
ACTIVE_COMPARATOR: Standard ICBT
Participants in the Standard ICBT condition will receive an 8-week transdiagnostic course for anxiety and depression called The Wellbeing Course, originally developed by Macquarie University, Australia.
|
All participants receive an 8-week transdiagnostic course for anxiety and depression called The Wellbeing Course, originally developed by Macquarie University, Australia.
The course is comprised of 5 lessons, beginning with psychoeducation and an introduction to the cognitive behavioural model, and then introducing key skills for managing anxiety and depression, including thought challenging, de-arousal strategies, graded exposure, behavioural activation, and relapse prevention.
The course also includes supplementary resources that briefly provide information on related common concerns, such as managing worry, communication, assertiveness, problem solving, and a brief resource on sleep that provides limited psychoeducation and sleep hygiene information.
Participants receive weekly brief therapist support via secure message or telephone from qualified counselors (social workers, psychologists).

EXPERIMENTAL: Sleep-Enhanced ICBT
Participants in the Sleep-Enhanced ICBT condition will receive an 8-week transdiagnostic course for anxiety and depression called The Wellbeing Course, originally developed by Macquarie University, Australia.
In addition, participants in the Sleep-Enhanced ICBT condition will also receive a newly developed lesson designed to target insomnia.

Participants receive weekly brief therapist support via secure message or telephone from qualified counselors (social workers, psychologists).
A new sleep lesson will replace the existing resource, developed using a patient-oriented process, that provides information and skills to aid with insomnia.
The sleep lesson includes psychoeducation on the nature of sleep problems and factors that affect sleep, such as circadian rhythm.
Two key behavioural strategies are introduced: sleep restriction, which requires the patient to avoid napping and sleep on a strict schedule for several weeks until they begin to feel naturally sleepy at night; and stimulus control, which asks the participant to only spend time in bed when prepared to sleep and avoid other activities (e.g., work, TV) in bed.
Patients will record how much they sleep each night and provide ratings of sleep quality and fatigue each week.
Therapists will support patients in adjusting their sleep schedule.
Patients are encouraged to apply skills they learn during the Wellbeing Course to sleep problems, for example, by applying thought challenging to beliefs about sleep.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Insomnia Severity Index (ISI)
Time Frame: Week 1 (pre-treatment), Week 8 (post-treatment), Week 20 (follow-up)
|
Change in insomnia symptoms from pre-treatment (Week 1) to post-treatment (8 weeks) and from pre-treatment to follow-up (20 weeks).
The ISI is a brief measure of insomnia comprised of 7 questions that ask about difficulties falling asleep, staying asleep, and waking too early, which respondents answer on a scale from 0 (None) to 4 (Very Severe), producing a score between 0 and 28.
