RecruitingBehavioural interventionAssessing the Feasibility of Web-based Insomnia Treatment Among Prostate Cancer SurvivorsThis pilot study will recruit Black/African American prostate cancer survivors into a clinical trial and will randomize each person to 1 of 2 possible treatments - an internet-based treatment for insomnia called Sleep Healthy Using the Internet (SHUTi) or an educational website. SHUTi provides the treatment - cognitive behavioral therapy for insomnia - across 6 lessons, while the educational website is like an online patient brochure. The study will examine the feasibility of SHUTi to improve sleep and well-being among Black prostate cancer survivors. It will also examine whether SHUTi is acceptable to these survivors and will compare the effect of SHUTi versus the educational website on insomnia and non-insomnia patient-reported outcomes.
