Identifying elder abuse & neglect among family caregiving dyads: A cross sectional study of psychometric properties of the QualCare scale

Abstract

Background/objectivesUniversal screening for elder abuse and neglect is a current controversy in geriatrics, fueled by the lack of evidence on valid and reliable instruments. Since each U.S. State and many other countries have their own legal definitions of what constitutes elder abuse and neglect, this further complicates instrument development and clinical assessment. The purpose of this paper is to present data on the sensitivity and specificity of the QualCare Scale, an instrument with utility in detecting clinically significant elder abuse and neglect among older adults receiving care at home. DesignData used in this analysis were collected during a training program in which trainees completed assessments (N=80) of standardized case scenarios of caregiving dyads. Trainees completed the QualCare Scale during each assessment. SettingThis training program, including the assessments of the standardized case scenarios, was completed using a custom designed virtual-reality platform. Trainees were able to interact with the environment, older adult and caregiver within the case scenario. ParticipantsThirty-six nurses and social workers from two Michigan Medicaid Waiver Sites participated in the training program. Each participant assessed between one and five scenarios, yielding the sample of 80 assessments used in this analysis. MeasurementsThe research team designed each standardized case scenario to reflect whether or not the QualCare Scale subscale score should indicate reportable elder abuse and neglect per the State statute. Accordingly, the research team’s QualCare Scale scores for each scenario were used as the gold standard criterion of clinical significance for comparison against the participant’s assessment scores. ResultsSensitivity and specificity for each of the six QualCare subscales was determined. Overall, the subscales had high sensitivity (≥0.811) but a wide range for specificity (0.167–1.000). ConclusionThe QualCare Scale can be an effective tool in detecting clinically significant elder abuse and neglect among older adults receiving care at home. This tool is suitable and feasible for use by practitioners working in home care. The QualCare Scale score indicating clinically significant or reportable elder abuse and neglect can be raised or lowered to be consistent with State or Country statutes, or simply used to create appropriate care plans to support caregiving. Findings from the QualCare Scale can support the multidisciplinary team in planning for and evaluating preventative interventions.
