Clinical Trial Summary

The Self-care for Dementia Caregivers Study is a behavioral health intervention that uses digital monitoring tools and motivational health coaching to help caregivers of persons with dementia engage in a regular routine of self-care. Participants wear an apple watch for the objective collection of sleep-wake rhythms. They receive personalized feedback on their sleep-wake rhythms via a new app. Health coaches call participants weekly, for 6 weeks to help participants meet their health/sleep goals and promote self-knowledge of regular routines. Participants will help the study team improve the design elements and content of the mobile app. The goal of this intervention is to reduce psychological distress and caregiver burden.


Description:

Caregivers of family members with Alzheimer's Disease (AD) and AD-related dementias (ADRD) experience high rates of psychological stress, physical impairments, and often, disruptions in normal daily activities. Caregivers must be alert both at night and during the day, and often on an inconsistent schedule. As a result, caregivers are less likely to sleep, exercise, and be socially active on a regular schedule. Disruptions of these biological and behavioral time cues, or "zeitgebers", in turn decrease the stability of the body's biological clock, placing caregivers at high risk for adverse health outcomes related to an out-of-sync biological clock (e.g. diabetes, cardiovascular disease, and depression, among others). Caregivers of individuals with ADRD experience worse health outcomes compared with other types of caregivers, likely due to more heavily or frequently disrupted schedules. For this research study, 25 individuals aged 50 and older who are providing care for a family member with mild-to-moderate dementia will be included. Data from 5 participants will be used for the development of an intervention manual (NIH Stage Model IA). A small pilot study will be conducted (NIH Stage Model IB) in which 20 participants will use a new mobile app - my rhythm watch - for up to 6 weeks. Objective actigraphic measures of the 24-hour pattern of sleep and daytime activity - known as the rest-activity rhythm (RAR) - will be measured continuously via the apple watch to evaluate circadian rhythms as a potential intervention target/mechanism of action. The investigators will measure the regularity, timing, and amplitude of behavioral patterns over a 24-hour period. Participants will be assessed at baseline, post-intervention, and 3-months post-intervention.

Study Design


Intervention

Behavioral:
Behavioral Self-Monitoring + Motivational Interviewing
Participants (n=20) will wear a iWatch to continuously measure their objective sleep-wake activity. The iWatch data sync to the new myRhythmWatch app, where participants will monitor their behavioral rhythm. Participants will also interact with a 'health coach' about their recorded behaviors weekly. This health coach will use motivational interviewing to enhance older adult caregivers' confidence and intrinsic motivation to engage in regular self-care.

Outcome

Type Measure Description Time frame Safety issue
Primary Change from baseline in Caregiver Burden throughout research study The Zarit Burden Interview is a self-reported questionnaire that assesses caregiver burnout. Caregiver Burden will be assessed throughout the study, namely pre- and post-intervention and at 3-month follow-up. A score of 0-10 indicates mild to no burden and a score of 20 or higher indicates a high level of burden, or worse result. Up to 4.5 months
Secondary Change from baseline in depressive symptoms throughout research study The 9-item Patient Health Questionnaire (PHQ-9) scale is a self-reported questionnaire to be completed by the participant that assesses severity of depression. The PHQ-9 will be administered throughout the study to assess changes in depressive symptoms pre- and post-intervention, and at the 3-month follow-up visit. A minimum score on this metric is a 0, indicating no impact to patient health, and ranges up to a maximum score of 27, indicating more severe impacts to patient health. Up to 4.5 months
Secondary Change from baseline in anxiety symptoms throughout research study The 7-item Generalized Anxiety Disorder Scale (GAD-7) will be administered throughout the study to assess changes in anxiety symptoms pre and post-intervention, and at 3-month follow-up visit. The whole scale score can range from 0 to 21, with severity increasing as values increase. The threshold of 5 or higher indicates mild anxiety symptoms, 10 or higher indicates moderate anxiety symptoms, and 15 or higher indicates severe anxiety symptoms. Up to 4.5 months
