Trial Outcomes & Findings for Delivery Models of Caregiver Support and Education (NCT NCT02368132)

NCT ID: NCT02368132

Last Updated: 2023-07-27

Results Overview

The Revised Memory and Behavior Problems Checklist (Reaction Subscale) measures CG distress in response to dementia-related symptoms. The RMBPC CG reaction subscale captured how bothered or upset CGs were in response to each endorsed dementia-related symptom (range=0-96, higher scores denote greater distress in response to symptoms)

Participant Flow

Caregivers (CGs) of Veterans with dementia receiving primary care at the Corporal Michael J. Crescenz VA Medical Center, VA Western New York Healthcare System, and their affiliated outpatient clinics were recruited and enrolled between May 2016 and November 2019. Participants were sent a letter introducing them to the study following either direct provider referral or upon a review of lists of patients prescribed memory-enhancing medications generated from the electronic medical record.

Participant milestones

Participant milestones
Measure
Usual Care
Caregivers randomized to UC will be sent general material about VA and community resources for patients with dementia and their CGs. With the exception of this material, individuals in this group will receive usual care and will be contacted again at 3, 6, and 12 months for follow-up research assessments.
Individual Delivered TEP Arm
Two mandatory modules that cover the stages of dementia and provide a brief introduction to problem solving techniques, action plan development, and coping skills, plus a menu of additional modules covering various content areas evaluated during the course of the monthly assessments (e.g., communication skills, behavioral management techniques, stress management and coping skills, longterm planning, etc.). Each individual TEP session will begin with reviewing education related to the selected module. The remainder of each session will involve coaching the caregiver on emotion-focused and problem focused coping strategies. The care manager will also discuss problem solving with the CG to reinforce the action plan and the educational component of the intervention.
Group Delivered TEP Arm
All TEP modules will be in a group format. Each call will take 1.5-2 hours. Each group will be comprised of 5-8 CGs who will call into a teleconference line at a pre-specified time. Groups will include spouse/partner-only or adult child-only CGs. The content of the calls will mirror those in the individual TEP delivered program. In addition to the group calls, they will receive individual care management.
