The development of military acute stress scale

Abstract

Objective To develop the military acute stress scale and examine the reliability and validity of this scale. Methods Based upon the previous acute stress researches and the rule of psychometrics, the military acute stress scale was compiled according to open-ended inventory survey. A total of 630 personnel were chosen by random cluster sampling, and tested with this scale, 50 of them were tested by Chinese Military psychosomatic health Scale simultaneously, and 50 of them were retested after two week.The reliability and validity were examined by exploratory factor analysis, confirmatory factor analysis and correlation analysis. Results The military acute stress scale was comprised of 9 factors and one lie sub-scale; Main fit indexes of model were the following CMIN=1219.476, DF=593, P=0.000, CMIN/DF=2.056, IFI=0.927, TLI=0.902, CFI=0.924, RMSEA=0.059; The correlation coefficients between subscales and subscales were 0.284-0.572.The correlation coefficients between subscales and total scale were 0.700~0.846 (P<0.05 or 0.01); The correlation coefficients was significant between this scale and Chinese military psychosomatic health scale.The correlation coefficients were 0.338-0.962 (P<0.01) .The test-retest correlation coefficients of total scale and subscales were 0.379-0.909(P<0.01). The Cronbaeh's α coefficients were 0.606-0.926; and the split-half correlation coefficients were 0.466-0.855. Conclusion The military acute stress scale has acceptable psychometrics properties on reliability and validity. Key words: Military personnel; Acute stress; Scale; Reliability; Validity
