Evaluation of the users violence in primary health care: Adaptation of an instrument.

: According to the World Health Organization, one out of every four violent workplace acts takes place in the health setting. The aims of the study are to study the prevalence of workplace violence in primary healthcare (PHC) professionals by adapting the Healthcare-worker's Aggresive Behaviour Scale-Users (HABS-U), to establish the frequency of exposure to hostile indicators and to determine which professional group is most exposed. : Study through qualitative and quantitative methodology in PHC professionals of the Region of Murcia (Spain). In the qualitative phase in-depth interviews were conducted and during the quantitative phase the instrument was used to 574 professionals of 39 PHC centres. : The resulting scale shows excellent psychometric properties and correlates significantly with job satisfaction, burnout components, the factors of empathy and psychological well-being. There was a 90.2% prevalence of user violence, and non-medical personnel were found to be the professional group most exposed. : The distribution of user violence is not homogeneous among the different professional groups of PHC. The adaptation of the scale may be useful for detection of user violence, as well as to evaluate the efficacy of intervention programs.
