The Effectiveness of Online Treatment for Insomnia in Cancer Survivors

Chronic Insomnia Clinical Trial

Official title: The Effectiveness of Online Treatment for Insomnia in Cancer Survivors: A Randomized Controlled Trial

Status Active, not recruiting

Clinical Trial Summary

Chronic insomnia affects more than 25% of cancer survivors, a rate double that of the general population. The Pan-Canadian sleep guideline for adults with cancer recommends Cognitive-Behavioral Therapy for Insomnia (CBT-I) as the best treatment. Major problems, however, are the lack of available CBT-I at cancer centers and the lack of information about possible side-effects of CBT-I. To address this issue, our study will evaluate the effectiveness and potential short-term side-effects of an online version of CBT-I. It is expected that when compared to cancer survivors who receive an online sleep education program, those who receive online CBT-I will experience improved sleep, mood, and quality of life, as well as reduced anxiety and fatigue.

Clinical Trial Description

Insomnia is a common adverse effect of cancer and its treatment. More than 25% of cancer survivors meet diagnostic criteria, a rate at least two times higher than that of the general population. Despite the pervasiveness of the problem, insomnia is underdiagnosed and undertreated in cancer survivors, resulting in significant suffering and associated consequences such as fatigue, cognitive issues, mood disturbance, functional disability, decreased quality of life, and immunosuppression. Consistent with recent evidence that group cognitive behavioral therapy for insomnia (CBT-I) is effective in treating insomnia in cancer survivors, CBT-I is recommended as first line treatment in the new Pan-Canadian practice guideline for sleep disturbance in adults with cancer. A major barrier to practical application of this recommendation however, is the lack of appropriately trained professionals at cancer centres. Moreover, it is assumed that in contrast to pharmacotherapy, CBT-I is free of treatment-related side-effects; however, we have no knowledge of symptoms that may be experienced by cancer survivors and/or exacerbated during CBT-I treatment (e.g., increased fatigue, cognitive impairment) because such effects are not systematically monitored. With the goal of improved access to CBT-I, online versions have been developed. One initial evaluation has been conducted in cancer patients with promising results, although limitations of the study include a small sample size (n = 28), control condition that failed to match for modality and time, lack of follow-up data, and failure to investigate potential side effects during treatment. Further inquiry is clearly warranted and consistent with insights of Canadian cancer patients who have suggested the use of technology as a factor that would facilitate their participation in an insomnia treatment program. Specific research questions to be addressed in our proposed two-group, randomized, controlled trial include: 1) Do cancer survivors with chronic insomnia who receive a 6-week, internet-based CBT-I treatment have greater improvement in insomnia severity and other secondary sleep and quality of life outcomes, than participants in an online sleep education control group? 2) Are there short-term side-effects associated with CBT-I for cancer survivors (i.e., do participants get worse before they get better)? Adult outpatients diagnosed with any type of cancer (stages I-III), completed active treatment for at least 1 month (with the exception of hormone therapy) and without cancer recurrence will be will be recruited from The Ottawa Hospital Cancer Centre and Cancercare Manitoba (n = 150). All will meet established diagnostic and research criteria for chronic insomnia. Prior to acceptance in the study, the procedures will be fully explained, inclusion/exclusion criteria assessed, and formal consent obtained. Once accepted into the study, participants will be randomized (stratified by hormone therapy-yes or no) to one of the two study arms. Online assessment measures (insomnia severity, pre-sleep arousal, beliefs about sleep, fatigue, mood, anxiety, quality of life) will be completed at the baseline period, at week 6 (post treatment), and at 3 month follow-up; however, online diary assessments of sleep parameters and potential side-effects (fatigue, affect, cognition, pain, drug dosing) will be entered daily and potential side-effects will also be assessed online weekly through the course of treatment. Analyses will involve mixed modeling and latent growth curve models. The computerized intervention evaluated in this study has the potential to bridge an existing gap in knowledge translation by providing cancer survivors widespread access to CBT-I in a cost-effective manner. The study will also investigate potential short-term side-effects of online CBT-I so that patients can be fully informed when making treatment decisions. The online program could serve as the foundation of a stepped care model as recommended in the Pan-Canadian sleep guideline for adults with cancer. Overall, by reducing the burden of residual effects of cancer and its treatments, this research aims to enhance quality of life for cancer survivors in Canada and elsewhere. ;
