Process evaluation of the residential care transition module

Area of Science:

• Gerontology
• Psychiatry
• Health Services Research

Background:

• Dementia caregiver intervention research often overlooks the mechanisms driving positive outcomes.
• The Residential Care Transition Module (RCTM) is a telehealth intervention designed to support family caregivers of individuals with dementia after institutionalization.
• This study evaluates the RCTM's process, delivery, fidelity, and mechanisms of benefit.

Purpose of the Study:

• To conduct a process evaluation of the RCTM telehealth intervention for dementia caregivers.
• To examine treatment fidelity, implementation factors, and mechanisms of benefit.
• To understand how the RCTM influences caregiver subjective stress and depressive symptoms.

Main Methods:

• A parallel convergent mixed-methods design was used, integrating quantitative and qualitative data.
• 240 primary caregivers were randomized to the RCTM or an attention control group.
• Data collection included study logs, treatment review checklists, and semi-structured interviews with 30 caregivers.

Main Results:

• High fidelity delivery of the RCTM was observed, with 89% of caregivers completing all sessions.
• Caregivers reported high utility and acceptability of the intervention.
• Increased frequency and duration of ad hoc support sessions were significantly associated with greater reductions in depressive symptoms and care-related stress.

Conclusions:

• The RCTM demonstrates high fidelity and strong caregiver engagement, providing valuable emotional support and informational counseling.
• Flexible, ad hoc support sessions appear crucial for enhancing the intervention's effectiveness.
• Findings can guide the adaptation and implementation of the RCTM for dementia caregivers in residential long-term care settings.
