Dyadic Life Review Intervention for Older Patients With Advanced Cancer and Alzheimer's Disease and Related Dementias and Their Caregivers

The purpose of this study is to evaluate the efficacy of Dyadic Life Review (DLR) therapy for reducing caregiver distress, measured by caregiver burden to capture the multifaceted experience of distress, among older adults with advanced cancer and cognitive impairment and their caregivers. This randomized controlled trial will enroll dyads and compare DLR to a waitlist control condition in which participants receive usual care and are offered DLR following completion of study procedures. In addition to examining the effects of DLR on caregiver burden, the study will explore whether DLR improves dyadic coping and relationship quality within the patient-caregiver relationship and identify patient and caregiver characteristics associated with greater intervention benefit. Findings from this study will provide preliminary evidence regarding the efficacy of DLR and inform future intervention development and implementation for older adults with cancer and cognitive impairment and their caregivers.
