Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT05178992). This is a study registration, not published results. Lead sponsor: Vanderbilt University. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 142 participants (ACTUAL). Conditions: Alzheimer Disease. Interventions: BEHAVIORAL: Socially Assistive Robot Activity. Primary outcome measures: Change in Apathy Score on the Clinician-rated Apathy Evaluation Scale (AES-C) , Baseline, Week 4, Week 8. Brief summary: The objective of this study is to demonstrate the impact of a socially assistive robot system on reducing apathy among cognitively impaired older adults residing in long term care facilities. Earlier phases of this project demonstrated the feasibility and acceptability of the robotic system. First, investigators will improve the social robotic interaction architecture through additional software development, enhance its versatility, and make it easy for non-experts to run. Second, 188 participants will be randomized to either usual activity programs at the long term care facility, or the usual activity programs plus the robotic activities. Researchers will examine the effect on apathy and also plan on examining underlying individual and facility factors that influence the impact of the robotic activities.
