Preliminary translation of 'Reducing Disability in Alzheimer's Disease' among individuals with intellectual disabilities and caregiver dyads.

This was a secondary analysis of a quality-improvement service, not a prospective randomised trial. There was no comparison group and only pre-post testing, so causal inference was not possible. There was no long-term follow-up. Only 23 of 44 dyads completed at least 75% of the intervention, so dropout was high. Outcome data were incomplete: 21 caregivers completed strain and physical activity questions, 18 completed unmet needs, and 12 completed NPI-Q. Physical activity was measured by caregiver report rather than by device, so estimates may be inaccurate. All individuals with intellectual disabilities and 80% of caregivers were non-Latino White, so generalizability is limited. Missing data approaches were not defined before analysis, and agencies adapted delivery and outcome collection to local workflows.

The implementation was funded by a cooperative agreement with the US Department of Health and Human Services Administration for Community Living. The Collaborative worked with the funding agency to identify the outcome set. The authors declared no conflicts of interest.

Do not read this as proof that RDAD-KC improves physical activity, behavior, or caregiver outcomes. The changes were not statistically significant, there was no comparison group, and only 23 of 44 dyads completed at least 75% of the intervention.
