PURPOSE: The purpose of this study was to develop an instrument that measures response to acute @entity130 exposure for firefighter and emergency medical service (EMS) personnel. The Acute @entity130 Exposure Response Scale (ATERS) was intended to assess firefighter and EMS personnel response to acute @entity130 exposure from analytical, emotional, and physical perspectives. METHODS: Data were analyzed on 97 firefighter and EMS personnel employed by a fire department in a mid-sized city in a western state. Principal component analysis (PCAR) using Winsteps software was employed to discover which variables in the set formed logical subsets that were independent of one another and included item analyses and assessment of internal consistency reliability (Cronbach's alpha). Rasch analysis included examination of dimensionality, @entity1 and item reliability, scale use and function, and construct validity including @entity1 -item fit statistics. RESULTS: Principal component analyses of residuals (PCAR) revealed three primary scales which were termed Emotional Psyche, Coping Ability, and Support Systems. Rasch analyses showed the ATERS performance to be acceptable as a new pilot measure with three distinct scales through reliability of @entity1 separation of .81 for Emotional Psyche, .66 for Coping Ability, and .63 for Support Systems, respectively (Nunnally and Bernstein, 1994; Carmines and Zeller, 1979; Devellis, 2012). The Rasch item reliability was .96 for Emotional Psyche, .95 for Coping Ability, and .97 for Support Systems. Response scale use and function was appropriate for each subscale. Validity was supported through PCA by evidence of good internal consistency. High item correlations indicated the items for each subscale were measuring a single construct. Likewise, Rasch analyses provided evidence of validity through an even spread of @entity1 ability to item difficulty for each of the three constructs. Good item fit provided proof of construct relevant variance and the absence of gaps along the unidimensional continuum indicated each construct to be represented adequately. CONCLUSION: The ATERS performs well as a measure of acute @entity130 exposure response for three primary constructs: Emotional Psyche, Coping Ability, and Support Systems with good Rasch @entity1 internal consistency reliability and factor structure. Items were deleted for each scale following PCA and Rasch analyses due to misfit and low loadings. Further research is recommended to optimally represent each construct in regards to @entity1 -item fit. Fire departments may utilize results of this study to assess current program effectiveness. Through evaluation, departments may incorporate programs and resources that are more effective at reducing stress associated with acute @entity130 , thereby increasing employees overall job satisfaction and performance.
