Brief summary
Insomnia affects 30-60% of cancer patients, thus making it one of the most common disturbances in this population. When untreated, which is the rule rather than the exception, insomnia often becomes chronic. Chronic insomnia is associated with numerous negative consequences (e.g., increased risk for psychological disorders, health care costs). A large body of evidence supports the efficacy of cognitive-behavioral therapy for insomnia (CBT-I) in cancer patients, but CBT-I is still not offered routinely in cancer clinics. Self-administered CBT-I (e.g., video-based intervention) has been developed to increase patients' access to this treatment. However, results of clinical trials have suggested that these minimal treatments would be better used as a first step of a stepped care model. In stepped care, patients receive only the level of intervention they need. Generally, the entry level is a minimal, less costly, intervention (e.g., self-help intervention) followed by a more intensive form of treatment if needed (if the patient is still symptomatic). The investigators have recently assessed the efficacy of a stepped care model to administer CBT-I in cancer patients, which includes a web-based CBT-I (called Insomnet) followed by up to 3 sessions with a psychotherapist if the patient is still symptomatic. Results of this study suggest that this model of care is non-inferior to a standard face-to-face treatment (Savard, Ivers, et al., in revision), while being more cost-effective. A stepped care CBT-I could therefore be offered in routine cancer care clinics. This project will assess the feasibility and effectiveness of implementing a stepped care CBT-I in real-world cancer clinics, using a non-randomized stepped wedge design to compare the effects of our program (active phase) with a passive phase. The program is called Insomnia in Patients with Cancer - Personalized Treatment (IMPACT). The stepped care CBT-I (active intervention) is being implemented sequentially in the four participating hospitals over a number of equally spaced time periods of 4 months (wedges), for a total of 5 time points, over a period of 20 months.
Interventions
Each week, the patients first have to read written information on the website (www.insomnet.ca), and then watch a video capsule (duration between 5 and 20 min each). Patients complete their daily sleep diary electronically on the website and the content is interactive. It includes the sending of automated emails to remind participants to complete the treatment tasks and encourage adherence, provision of tailored feedback (e.g., texts, charts) based on the information that they provide in their sleep diary, as well as quizzes with automated correction to reinforce patients' understanding of the content.
BEHAVIORALProfessionally-administered booster face-to-face CBT-I sessions
Patients who obtain an ISI score of 8 and more after completing the web-based CBT-I are stepped up and offered to receive up to three 50-min booster sessions of CBT-I offered individually by a psychologist (if needed). Remitted patients (good sleepers; ISI score lower than 8) will receive no further treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 2) Psychologists' perceived self-efficiency | Throughout the active phase, up to 20 months | Psychologists' perceived self-efficiency in using CBT-I protocol (%) |
| 4) Change in wake after sleep onset (WASO) | Pre-treatment and post-treatment (6-8 weeks later) | Change in daily sleep diary parameters from pre- to post-intervention: Change in wake after sleep onset (WASO) = Summation of nocturnal awakenings. |
| 5) Change in total wake time (TWT) | Pre-treatment and post-treatment (6-8 weeks later) | Change in daily sleep diary parameters from pre- to post-intervention: Change in total wake time (TWT) = Summation of SOL, WASO, and early morning awakening. |
| 6) Change in total sleep time (TST) | Pre-treatment and post-treatment (6-8 weeks later) | Change in daily sleep diary parameters from pre- to post-intervention: Change in total sleep time (TST) = Time in bed minus total wake time. |
| 7) Hospital Anxiety and Depression Scale (HADS) | Pre-treatment and post-treatment (6-8 weeks later) | Change scores from pre to post-intervention: Hospital Anxiety and Depression Scale (HADS): A 14-item questionnaire comprising 7 items assessing depression and 7 items assessing anxiety. Scores obtained for each subscale range from 0 to 21. |
| 8) Fatigue Symptom Inventory (FSI) | Pre-treatment and post-treatment (6-8 weeks later) | Change scores from pre to post-intervention: Fatigue Symptom Inventory (FSI): A 14-item questionnaire measuring perceived fatigue. Each item is rated on an 11-point Likert scale, ranging from 0 to 10. A higher score indicates a higher level of fatigue or interference or a longer duration of fatigue. |
| 9) The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) | Pre-treatment and post-treatment (6-8 weeks later) | Change scores from pre to post-intervention: The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30): A 30-item questionnaire. Scores are transformed to give a score ranging from 0 to 100. |
