Overview
Brief Summary
Disturbed sleep is stressful to persons living with dementia (PLwD) and their caregivers. It contributes to earlier placement of the PLwD in nursing homes and increase the risk for many psychological and cognitive health issues and poor quality of life for both the PLwD and the caregivers. Given the potential harmful side effects of medications, non-medication alternatives, such as Cognitive Behavioral Therapy for Insomnia (CBTi), may be safer to improve disturbed sleep in this population. CBTi which includes stimulus control, sleep compression, relaxation, sleep hygiene, and cognitive restructuring, is effective and has durable and sustained effects on sleep outcomes over the long-term. CBTi has improved sleep disturbances in PLwD and their caregivers, separately. Since disturbed sleep in the PLwD-caregiver dyad is bidirectional and interdependent, targeting the pair as a unit for intervention has the potential to lead to improved sleep and health outcomes for both persons. There is no current published research on CBTi when the PLwD and their caregivers receive the intervention at the same time; as a result, the researchers will examine the 1) feasibility; 2) acceptability; and 3) preliminary efficacy of 4-week CBTi intervention for community-dwelling PLwD and their caregivers who are both experiencing sleep disturbances. Forty PLwD-caregiver dyads will receive CBTi via videoconferencing sessions. Preliminary efficacy of the intervention will be assessed using objective (actigraphy) and subjective sleep quality measures. In addition, semi-structured interviews will be conducted to examine the acceptability and satisfaction with the intervention.
Detailed Description
Up to 71% of the persons living with dementia (PLwD) and 70% of their caregivers experience sleep disturbances, which are distressing for both the PLwD and their caregivers. Specifically, PLwD often experience restlessness and fragmented sleep, which in turn can affect caregivers' sleep patterns leading to multiple nightly awakenings, shorter sleep duration, and/or inconsistent sleep-wake times. These disturbances increase the risk for a myriad of psychological, cognitive, behavioral, and physiological health issues and poor quality of life for the dyad. Given the interdependence of the dyadic sleep disturbances and the negative health consequences of sleep disturbances on the dyad, there is a critical need to develop and provide effective interventions to improve their sleep. Pharmacologic treatment often results in potential harmful side effects like falls and cognitive decline; therefore, non-pharmacologic approaches are recommended for this population. Cognitive behavioral therapy for insomnia (CBTi), a non-pharmacologic intervention that has demonstrated effectiveness for improving sleep disturbances in multiple populations, is delivered in various formats including face-to-face and videoconferencing. Individually, PLwD and caregivers have successfully deployed behavioral sleep techniques, resulting in improved sleep quality. However, there is no current published research on CBTi completed simultaneously by the PLwD-caregiver dyad, and that is exactly what the researchers of this study seek to do with early-stage individuals and their caregivers. The researchers premise this effort on the notion that a dyadic intervention can use early-stage individuals' retained capacity for communication and comprehension to establish in-the-moment agreements about strategies the caregiver can employ to enact and facilitate positive sleep behaviors in the PLwD and to pair that with acquired strategies to engender his/her own positive sleep behaviors. This project seeks to gather formative and preliminary data on CBTi delivered simultaneously to the PLwD-caregiver dyad. The researchers will use a quantitative, descriptive approach to determine the feasibility, acceptability, and preliminary efficacy of a 4-session CBTi intervention administered to 40 PLwD-caregiver dyads via videoconferencing sessions who will receive the intervention as a unit. Objective and subjective sleep, depressive symptoms, and cognitive health data will be collected at baseline, and 1 week and 3 months post-completion of the intervention. In community-dwelling PLwD and their caregivers where both persons in the dyad self-report sleep disturbances, the specific aims for this study are: 1. Assess the feasibility of a video conferencing dyad-based CBTi intervention. 2. Evaluate the acceptability of a video conferencing dyad-based CBTi intervention. 3. Examine the preliminary efficacy of video conferencing CBTi intervention on sleep quality outcomes including sleep efficiency and perceived sleep quality.

Outcomes
Primary Outcomes
Change in Adherence with Study Interventions
Time Frame: Weeks 1, 2, 3, 4
Feasibility of the interventions will be assessed with rates of adherence to the study components weekly and over the 4 weeks
Percent Attrition from the Study
Time Frame: Week 4
Feasibility of the interventions will be assessed with the percent of participants leaving the study over the 4 week intervention.
Acceptability the Intervention
Time Frame: Week 5 (1 week post-intervention)
Acceptability of the interventions will be assessed with a qualitative interview with caregivers after completing the intervention. There is not a summary score for the open-ended questions asked during the interview.
