Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Sharing History through Active Reminiscence and Photo-imagery (SHARP) Program engages triads (primary caregiver, person living with dementia, caregiver support person) in walking and social reminiscence, using a group tablet to access routes and historical neighborhood images serving as conversational prompts. Focus is on adapting the SHARP model to older Black dementia caregivers and on caregiver physical and mental health. Study technology measures sleep and daily step count. Weekly online surveys assess health status. Pre-post assessments measure cognitive function and mental health. Focus groups assess adaptation needs, feasibility and acceptance, and cultural significance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Sharing History through Active Reminiscence and Photo-imagery (SHARP) Program is a recently developed culturally celebratory, multimodal approach to physical, social, and reminiscence activity. The SHARP walking application, accessed on a group tablet, is preloaded with 72 themed, 1-mile neighborhood routes with GPS-linked "Memory Markers," historical neighborhood images and questions, to prompt conversational reminiscence about Black life, history, and culture. In this Stage I study, walking triads consist of a healthy or mildly cognitively impaired (MCI) primary dementia caregiver (aged 55+), the care partner - a person living with early-stage dementia (PLWD) or MCI (aged 55+), and a healthy or MCI caregiver support person (aged 18+). Triads walk 3x/week over 16 weeks in the gentrifying, historically Black neighborhoods of Portland, Oregon. The primary caregiver wears an actigraphy watch, uses an under-the-mattress sleep sensor, and on a weekly basis, measures weight on a study-provided digital scale and completes a health update survey. Watch, sleep sensor, and weekly measures are optional for the PLWD. We aim to (1) adapt SHARP implementation, technology, and protocol for caregivers of PLWD, and (2) test preliminary efficacy of this intervention on dementia caregivers' physical and mental health.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Triads are randomized into either the intervention group or the waitlist control group. The intervention group walks for 16 weeks. The waitlist control group completes baseline measures for 16 weeks then continues measures while walking 16 weeks. Wearable technology and weekly surveys are optional for PLWD.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention Group

Caregivers (MCI or healthy) randomized into this group walk 3x/week for 16 weeks with their care-partner (person living with early-stage dementia - PLWD) and their caregiver support person (MCI or healthy). Caregivers (and optionally for PLWD), wears an actigraphy watch, uses an under-the-mattress sleep sensor, and on a weekly basis completes weight and a health update survey. Mid- and end-study focus groups evaluate program effectiveness and needed adaptations.

Group Type EXPERIMENTAL

SHARP - Physical and social activity

Intervention Type BEHAVIORAL

Technology-enabled neighborhood walking 3x/week for 16 weeks with conversational reminiscence

Waitlist Control

Caregivers (MCI or healthy) randomized into this group first complete baseline measures for 16 weeks, consisting of wearing an actigraphy watch, using an under-the-mattress sleep sensor, and, on a weekly basis, completing weight and a health update survey. These baseline measures are optional for PLWD. After 16 weeks of baseline data collection, the primary caregiver continues these measures while walking 3x/week for 16 weeks with their triad. The PLWD optionally completes measures and optionally wears the watch and sleep sensor. Mid- and end-study focus groups during the walking phase evaluate program effectiveness and needed adaptations.
