iCANSleep: Smartphone App-Based Insomnia Treatment for Cancer Survivors

Summary

The investigators will answer the question of whether treating insomnia using the mobile-app-based intervention of Cognitive Behavioural Therapy for Insomnia (CBT-I) for cancer survivors ("iCANSleep") can improve symptoms of insomnia in Canadian cancer survivors compared to a waitlist control group. The investigators will recruit 146 people with insomnia who have completed cancer treatment at least 3 months prior to the study.

* Individuals with non-hematological malignancies must show no evidence of cancer or clinically stable/inactive disease for a minimum of 3 months prior to enrollment (for individuals with non-metastatic cancer) or be on a stable treatment regimen for the prior 3 months (for individuals with metastatic cancer) to ensure that insomnia is not a direct, acute response to cancer treatment.
