abstract="INTRODUCTION: Investigation into the psychological effects of violence toward health care workers and its associated trauma is increasing. The Impact of Event Scale (IES) provides a measure of current, subjective, emotional distress symptomatic of a specific traumatic event. However, its validity among paramedics is largely unknown. PROBLEM: The purpose of this study was to investigate the psychometric properties and factor structure of the IES with a sample of Australian paramedics. <br><br>METHODS: The study aimed to investigate the psychometric properties and factor structure of the 15-item IES with a sample of Australian paramedics using Exploratory Factor Analysis with model fit statistics as found in confirmatory analysis. <br><br>RESULTS: Maximum Likelihood Factor Analysis with Varimax rotation supported the hypothesis that a two-factor solution would provide the best fit of the data. Procrustes rotation provided further support for this hypothesis indicating that the factors, labeled &quot;Intrusion&quot; and &quot;Avoidance&quot;, as well as the individual items of the 12-item final model, were a good fit to an ideal solution. <br><br>CONCLUSION: The revision of the scale has improved its validity for use in the general population of paramedics, improving the potential for its use in trauma-related research.<p /> <p>Language: en</p>",
