ABSTRACT

Background and Objectives. In testing a comprehensive decision support system for Adult Protective Services (APS), this study addressed two problems common in APS research and practice: the psychometric quality of the measures and measurement burden. Research Design and Methods. Data were generated on 1,472 APS cases over six months in two California counties using the Identification, Services and Outcomes (ISO) Matrix, a comprehensive decision support system for APS. The ISO Matrix uses Short-Forms developed from the Elder Abuse Decision Support System (EADSS). Mini-Forms were developed from the Short-Forms and tested in order to reduce measurement burden. Mini-Forms were developed on each measure using sensitivity and specificity of the items in predicting the criterion of substantiation (yes/no). Psychometric quality was addressed by estimating predictive validity and Cronbach’s alpha of Short-Forms. Predictive validity and reliability were also estimated on the Mini-Forms as was their correlation with the Short-Forms. Results. On Short-Forms, good predictive validity was found for all measures except those that were very rare. Results for even shorter Mini-Forms were mixed, and some will require further research on their reliability and validity. Discussion and Implications. Short-Forms had good psychometric properties and some Mini-Forms did as well. Ongoing adoption by several California counties and Montana demonstrates the viability and sustainability of using the ISO Matrix for research and practice.

摘要

背景和目标。在测试成人保护服务 (APS) 的综合决策支持系统时，本研究解决了 APS 研究和实践中常见的两个问题：测量的心理测量质量和测量负担。研究设计和方法. 使用识别、服务和结果 (ISO) 矩阵（一个针对 APS 的综合决策支持系统），在 6 个月内在加利福尼亚州的两个县生成了 1,472 个 APS 案例的数据。ISO 矩阵使用从虐待老人决策支持系统 (EADSS) 开发的简表。Mini-Forms 是从 Short-Forms 开发出来的，并经过测试以减少测量负担。使用项目的敏感性和特异性来预测证实标准（是/否），针对每项措施开发了迷你表格。通过估计短表的预测效度和 Cronbach α 来解决心理测量质量问题。还评估了迷你表格的预测有效性和可靠性，以及它们与简短表格的相关性。结果. 在 Short-Forms 中，除了非常罕见的那些测量之外，所有测量都具有良好的预测效度。更短的迷你表格的结果好坏参半，有些需要进一步研究其可靠性和有效性。讨论和影响。Short-Forms 有很好的心理测量特性，一些 Mini-Forms 也有。加州几个县和蒙大拿州的持续采用证明了使用 ISO 矩阵进行研究和实践的可行性和可持续性。
