Objectives: This pilot study describes implementation procedures of goal attainment scaling (GAS) and examines the feasibility of using GAS to measure the multifarious intervention outcome of case resolution in elder mistreatment (EM) adult protective services (APS).Methods: Substantiated EM victims (n = 27) were recruited prospectively from the State of Maine APS. An adapted GAS approach was implemented involving development of a prepopulated goal scale menu and web-based GAS application.Results: The GAS menu comprised 18 goals and corresponding scales spanning several domains of case resolution: social support, service access, health/functioning, enhancing independence, and protective measures. The overall GAS process had mean length 33.8 min per case. The mean GAS summary t-score (54.3) aligned with theoretical expectations.Discussion: Without a measure of case resolution, research cannot compare the effectiveness of different EM intervention models. Findings suggest that GAS is a feasible, client-centered strategy to measure the multifarious EM intervention case resolution outcome.
