In order to reduce workplace violence in the health care sector, a pervasive and increasing problem, a “total organizational response” is necessary to engage every member of the organization in change. Staff members need regularly updated training on a variety of topics related to workplace safety and aggression management while managers must be responsible for assessing risk, developing policies and protocols, and organizing staff training. While aggression management training is widely available, it has rarely been subjected to evaluation. The authors contend that there are a variety of possible measures of change that can be used to objectively evaluate training courses. Published evaluations of trainings are reviewed to illustrate how training design and content are developed and to identify measures that have been used to assess the effectiveness of training courses. The authors conclude by combining several of the evaluation models presented in the review to create an integrated model of change measures to use for the evaluation of aggression management training courses.
