Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall objective of this mixed-methods proposal is to answer the focused research question: What tailoring is necessary and sufficient to achieve optimal engagement with and efficacy of Sleep Healthy Using the Internet (SHUTi) for caregivers? The SHUTi program is a fully-automated Internet-delivered cognitive-behavioral therapy for insomnia (CBT-I) program. We will identify caregiving-related user- and environment characteristics that affect the use and impact of SHUTi, and other Internet interventions more broadly, for caregivers. We will recruit 100 high-intensity caregivers with insomnia to complete a baseline assessment of insomnia and caregiving context. Caregivers will then receive access to SHUTi in an open-label trial. At the end of the 9-week intervention period, caregivers will complete post-assessment and be categorized according to their level of engagement with the 6 SHUTi intervention lessons (or weekly "Cores"). We will test whether caregivers' engagement with SHUTi (i.e., being a non-user vs. incomplete user vs. complete user) is associated with their caregiving-related user characteristics (i.e., caregiving strain, self-efficacy, and guilt) and environment characteristics (i.e., proximity to care recipient; care recipient functional, cognitive, and behavioral status; caregiving tasks). Caregivers' barriers to and motivations for SHUTi engagement will be described from open-ended survey responses specific to participants' level of engagement as part of post-assessment. We will identify non-users' barriers to SHUTi adoption, the extent to which barriers were related to caregiving, and what modifications may have increased their motivation to try SHUTi. We will also identify users' (incomplete and complete) SHUTi usage barriers and motivations, the extent to which these were related to caregiving, and how tailoring may improve usage by increasing salience to caregivers. Thematic coding will also examine how caregivers' recommendations generalize to other evidence-based digital health interventions. Among caregivers using SHUTi, we will test whether the effects of SHUTi on cognitive mechanisms of change targeted by SHUTi (i.e., more adaptive sleep beliefs, internalized sleep locus of control) are associated with differences in caregiving-related user or environment characteristics.

SHUTi (Sleep Healthy Using the Internet)

Participants will be assigned to the SHUTi (Sleep Healthy Using the Internet) online intervention. They will spend 1-2 hours each week for 6-9 weeks completing daily sleep diaries as well as interactive core content covering topics of sleep behaviors, sleep thoughts, sleep education, and relapse prevention. As users progress through the intervention, they will receive automated, tailored instructions for how to improve their sleep.
