Definitions and indicators of elder abuse: a delphi survey of APS caseworkers.

Instruments designed to measure specific types of elder mistreatment are not available, but they may be warranted after an initial screen indicates abuse or risk for abuse. The purpose of this study was to evaluate definitions for different types of elder mistreatment and validate the indicators as perceived by adult protective services (APS) caseworkers' opinions. Through 351 APS research network participants, a Delphi survey was completed. A 45% return rate was achieved for round one and 40% for round two with 70 same respondents from both rounds. These types of abuse, emotional abuse, exploitation of finances and/or property, neglect, physical abuse, and sexual abuse, have some similar and some extremely different indicators that singly and together expand their definition. Instruments to measure five different types of abuse are offered for caseworker or prevalence study use.
