Study: NCT04512768

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Transdiagnostic Internet-delivered Cognitive Behaviour Therapy
Description: 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).

Intervention: Brief Internet-Delivered Cognitive Behaviour Therapy for Insomnia
Description: 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.
