NiteCAPP: Web-based Cognitive Behavioral Treatment for Insomnia in Dementia Caregivers
Study Details
Study Description
Brief Summary
Over the next 30 years, more than 10 million persons living with dementia in the United States will receive care at home from an unpaid and untrained family caregiver. At home care is preferred by caregivers and persons with dementia alike, but increases the caregiver's risk of insomnia and related negative health outcomes, including depression, anxiety, cognitive disturbances and poor quality of life. Cognitive behavioral therapy for insomnia (CBT-I) is a highly effective and established evidence based treatment for adults of all ages. Although relatively understudied in dementia caregivers, the research by our group and others suggests CBT-I is also efficacious in caregivers. Our team developed a brief (4 session) CBT-I protocol specifically adapted for dementia caregivers (CBT-I) and has shown in person and remote (i.e. telehealth) delivery of this protocol significantly reduces insomnia symptoms and improves mood (moderate to large effects). Given demands on caregivers' time and limited availability of trained CBT-I providers, a web-based version of CBT-I (WebCBT-I; the online treatment will be called NiteCAPP) is needed to increase the accessibility of this efficacious treatment. WebCBT-I will allow for flexible at home scheduling, and the skills needed to monitor caregiver treatment progress can be quickly and efficiently taught to healthcare providers. The overarching goal of this project is to develop and test WebCBT-I in caregivers of persons with dementia.
Objectives
-
To examine the clinical and health characteristics, including sleep, pain, fatigue, cognitive abilities, and cardiovascular health in dementia caregivers with insomnia.
-
To examine changes in the primary clinical outcomes, including complaints of poor sleep, and fatigue.
-
To examine changes in the secondary clinical outcomes, including mood, daytime functioning, cognitive functioning, and cardiovascular health.
-
To examine the mechanistic variables, including arousal (heart rate variability, HRV).
