Examining Adult Protective Services Outcomes: Services Associated With the Decrease of Mistreatment Differed by Elder Mistreatment Type

Background and Objectives Adult Protective Services (APS) are the frontline agencies investigating elder mistreatment and providing/coordinating postinvestigation services. Yet, their effectiveness in reducing different types of mistreatment in relation to services is unknown. This study aimed to address the knowledge gap by identifying services provided by mistreatment type, and examining the associations of services with mistreatment reduction. Research Design and Methods A pretest-post-test design was implemented using the Identification, Services, and Outcomes (ISO) Matrix to assess mistreatment levels during case investigation and at case closure after services were provided. San Francisco and Napa APS participated in a 6-month data collection. Results The 4 most prevalent types of mistreatment were examined: emotional, physical, financial abuse, and neglect by others. On average, level of mistreatment decreased across mistreatment types after APS intervention. Care/case management, mental health, and other services were most common, while specific services differed depending on type of mistreatment. Care/case management services were associated with physical and emotional abuse reduction, legal services further correlated with emotional abuse reduction; financial planning services were associated with financial abuse reduction; care/case management and other services were associated with neglect reduction. Discussion and Implications This is the first study to address APS services by mistreatment type and the outcomes of services. Adoption of the ISO Matrix by APS programs opens the possibility of research and practice collaboration in APS outcomes research using a standardized approach.
