AbstractBackground: Bullying as a stressor in the workplace has been evaluated in numerous settings. It has never been evaluated in the emergency medical service (EMS) environment where bullying can occur from many different sources. The Negative Acts Questionnaire-Revised (NAQ-R) is a 22-question validated tool for evaluating bullying. Our hypothesis was that we could identify a shortened version of the NAQ-R that identifies bullying as accurately as the full screening tool. Methods: This was a cross sectional study of EMS providers in our local EMS transport agency. The local EMS agency transports approximately 50,000 patients per year and is a paramedic level response system. Results on the NAQ-R were on a 5-point Likert scale for each of 22 different categories of bullying that were summed by adding each questions 1-5 response for the 22 questions. Respondents were also categorized as victims or non-victims of bullying based on being positive for any of the 22 types of bullying at least once a week. We performed a binomial decision tree analysis and a cross-validation. Results: Data were collected from 153 providers. Mean age was 33 ± 10 years and 50% were male. Total years in EMS were 8 ± 8 years. NAQ-R summed results in our group ranged between 22 and 88, with an average of 40 ± 15. A NAQ-R score of 33 or less was 91% accurate in identifying non-victims and a score of 45 or more was 94% accurate in identifying victims. The majority at 51% (77/152) of respondents were victims of one or more types of bullying. A combination of five questions was 94% accurate in identifying a victim of bullying among EMS providers. Cross validation resulted in a misclassification risk estimate of 0.12 ± .03. Conclusion: NAQ-R bullying scores in EMS are similar or higher than numbers in other fields. Five questions on the NAQ-R were 94% accurate in identifying victims of bullying in EMS providers.
