adequately by importing measures for suspected risk factors from other settings. For example, good measures exist in the literature for cognitive impairment, dementia, handicap, and frailty. As well, some characteristics of individuals that may place them at increased risk of mistreatment, such as personality, stress, and the burden of caregiving, have been developed in the child mistreatment field and could be adapted to this research setting. For the most part, observational and hypothesis-driven research in the elder mistreatment field will have to develop measures that are specific to the field, such as measures of risk characteristics in trust relationships and aspects of settings that may be of interest. This is in addition to adapting measures of risk factors that have been developed in the child mistreatment field and in other research.
