Feasibility of a video-based cognitive behavioral therapy for insomnia in French adult cancer outpatients: results from the Sleep-4-All-1 study

Background Insomnia affects up to 63% of patients with cancer. Cognitive behavioral therapy for insomnia (CBT-I) is considered to be the non-pharmacological gold standard treatment, but it remains underutilized in France. Self-administered interventions offer new ways to overcome some of the barriers that restrict access to efficacious supportive care. Objective To assess the feasibility, among French adult cancer outpatients, of a validated Quebec video-based, self-administered, cognitive behavioral therapy for insomnia (VCBT-I). Methods A pre-post design with quantitative measures (Insomnia Severity Index, Edmonton Symptom Assessment System, Treatment Perception Questionnaire) and qualitative measures (semi-structured interviews) was used. Results One hundred and seventy-three cancer outpatients were self-screened for insomnia, and 57% (n=99) reported significant symptoms. Among them, 80% (n=79) agreed to participate in the VCBT-I. The download rate of the VCBT-I was 78% (n=62/79). Several technical and contextual barriers to the delivery and the applicability of the VCBT-I emerged. However, participants reported a high level of satisfaction, and some valuable benefits at post-immediate intervention (increased knowledge about sleep, better quality of sleep, and higher acceptance of the burden of insomnia), regardless of whether or not they still had insomnia. Discussion This study confirms that there is a demand for a VCBT-I, which was perceived as appropriate by a sample of French cancer outpatients with insomnia, but it also highlights some limitations in terms of implementation and practicality. Remote professional support appears to be a core need in order to address these issues and personalize the guidance process.
