The target population was the staff of the 115 Emergency from Medical Emergency Management Department of Lorestan. The sample size was calculated 217 based on Krejcie-Morgan table. Divergent and convergent validity were used to determine the validity of the structures, and Cronbach's alpha coefficient and combined reliability were used to determine the reliability of the instrument.
