Objectives. Defining and validating a measure of safety contributes to further validation of clinical measures. The objective was to define and examine the psychometric properties of the outcome "incidents of harm." Methods. The Incident of Harm Caregiver Questionnaire was administered to caregivers of older adults discharged from hospital by telephone. Caregivers completed daily logs for one month and medical charts were examined. Results. Test-retest reliability (n = 38) was high for the occurrence of an incident of harm (yes/no; kappa = 1.0) and the type of incident (agreement = 100%). Validation against daily logs found no disagreement regarding occurrence or types of incidents. Validation with medical charts found no disagreement regarding incident occurrence and disagreement in half regarding incident type. Discussion. The data support the Incident of Harm Caregiver Questionnaire as a reliable and valid estimation of incidents for this sample and are important to researchers as a method to measure safety when validating clinical measures.
目标。定义并验证一项安全指标有助于进一步验证临床指标。本研究的目的是定义并检验“伤害事件”这一结果的心理测量特性。方法。通过电话向出院的老年人的照料者发放《伤害事件照料者问卷》。照料者完成了为期一个月的每日日志，并对病历进行了检查。结果。伤害事件的发生情况（是/否；kappa系数 = 1.0）和事件类型（一致性 = 100%）的重测信度（n = 38）较高。与每日日志进行验证时，在事件发生情况或事件类型方面未发现不一致。与病历进行验证时，在事件发生方面未发现不一致，在事件类型方面有一半存在不一致。讨论。这些数据支持《伤害事件照料者问卷》可作为对该样本事件的可靠且有效的评估，对于研究人员在验证临床指标时作为一种测量安全性的方法具有重要意义。
