About this study

Resident-to-resident elder mistreatment (R-REM) is a significant problem in long-term services and support settings (LTSS), and likely to cause physical and or psychological distress. The proposed project tests an intervention developed for use by LTSS staff. As such, it represents an important step in the process of developing approaches for ameliorating and preventing R-REM in assisted living residences which house residents with dementia and related behavioral disorders, and is thus likely to have significant public health impact.

Conditions: Assisted Living, Resident to Resident Elder Mistreatment
Being tested: R-REM training

What participants receive

What is being measured

The primary outcome is the main question the study is designed to answer.

Falls, Accidents, and Injuries
Impact on falls, accidents, and injuries as measured by incident reports
Measured: Six months before baseline through twelve month follow-up

Limitations and caveats (from the sponsor): The pandemic may have affected the observed affect and behavior results which may have been impacted by missing data. During the pandemic there was more social isolation, impacting quality-of-life outcomes. There were several limitations to this study, most notably the large amount of missing data observed at the final wave in part because of COVID, affected testing the third study aim. To mitigate this loss, several statistical methods were used to examine missing data due to COVID.
