BACKGROUND AND AIM: Some people exposed to disasters will suffer from acute stressdisorder (ASD) due to the negative consequences of these disasters. Evaluating this disorder at alarge scale requires a credible and standardized tool. Therefore, the current study aims to investigatethe psychometric properties of the ASD questionnaire for people exposed to Kerman earthquake.METHODS: This is a descriptive‑tooling study, conducted on 435 men and women older than 18 yearsliving in earthquake‑affected areas of Kerman Province (Kouh‑e‑Banan). The study was carried outusing the Persian translating of the English version of the Diagnostic and Statistical Manual of MentalDisorders, Fifth Edition ASD questionnaire on accessible individuals living in temporary residencetents in two initial and final stages and different stages of validity and reliability evaluation was carriedout. The findings were analyzed using descriptive statistics and Pearson’s correlation coefficient.RESULTS: During the evaluation of content validity, no questions were eliminated. To carry outfactor analysis, sampling competence, and suitability of sample size were confirmed throughKaiser–Meyer–Olkin and Bartlett’s tests. In the factor analysis stage, 14 items in three factors weredefined. The factors were included reexperiencing and analysis, arousal (continuous irritability), andavoidance factors which together explained 59.43% of percentage distribution. In the next stageof evaluating divergent validity, the results indicated a significant and inverse correlation betweenASD score and quality of life score (r = −0.43, P = 0.002) of the participants, while there was alsoa positive and significant correlation between ASD score and general health disorder score ofthe participants (r = 0.47, P < 0.0001). The reliability of the questionnaire was investigated usingCronbach’s alpha, and inner class correlation coefficient was calculated to be 0.9.CONCLUSIONS: The tool investigated in this study has suitable validity and reliability and is effectivefor use by psychologists and relief workers for necessary interventions and prevention of ASD indisasters.
