REPAIR Sleep Study

Summary

The goal of this study is to learn whether a videoconference-delivered CBT-I program (REPAIR Sleep) can improve sleep and psychological well-being in caregiver-PLwD dyads. The main questions it aims to answer are:

* Does REPAIR Sleep improve insomnia severity and other sleep outcomes?
* Does REPAIR Sleep improve psychological outcomes such as mood, stress, and quality of life? Researchers will compare REPAIR Sleep with Healthy Living to see whether REPAIR Sleep leads to greater improvements.

Participants will:

* Attend five weekly virtual sessions
* Complete sleep diaries and questionnaires
* Wear an actigraphy device
* Complete follow-up assessments over 9 months

Conditions

• Cognition Disorder
• Alzheimer Disease

Interventions

BEHAVIORAL

REPAIR Sleep

REPAIR Sleep is a dyadic CBT-I program delivered via videoconferencing over 5 weekly sessions (60 minutes each). Core components include: * Stimulus control: establishing consistent wake times and strengthening the bed-sleep association * Sleep compression: gradually adjusting time in bed to improve sleep efficiency, using a milder form appropriate for older adults and PLwD * Relaxation training: techniques to reduce physiological and cognitive arousal at bedtime; can be practiced individually or together * Cognitive therapy: identifying and modifying unhelpful thoughts and beliefs about sleep and its consequences * Sleep hygiene education: optimizing environmental and behavioral factors that influence sleep The intervention uses written and recorded agreements and daily logs to support memory challenges in PLwD and to promote consistent practice of sleep behaviors. Both dyad members attend all sessions.

BEHAVIORAL

Healthy Living

Healthy Living is an attention-matched, 5-week behavioral health education program delivered via videoconferencing. Weekly 60-minute sessions cover: * Week 1: Healthy aging principles, components of a healthy lifestyle, nutrition basics, budgeting for nutritious meals, meal planning, and food journaling * Week 2: Sleep hygiene education, introduction to flexibility exercises and stretches, activity journaling, and goal setting * Week 3: Balance exercises, fall prevention strategies (including safe bed exits at night), and weight-bearing aerobic exercise * Week 4: Strength training using resistance bands and light weights * Week 5: Integration of exercise, nutrition, and sleep hygiene; review and goal setting for continued healthy living The program emphasizes goal setting, progress tracking, and behavioral reinforcement, with dyads encouraged to implement lifestyle changes and discuss successes and challenges during sessions.
