Abstract (544 Views)
Aims: This study aimed to evaluate the psychometric properties of and validate the Disaster Risk Management and Psychosocial Outcomes Scale in a sample of firefighters.
Instrument & Methods: In this descriptive-correlational study, a sample of 200 firefighters was selected through purposive sampling. The data were analyzed using descriptive statistics, exploratory factor analysis, confirmatory factor analysis, and convergent validity in SPSS 27 and AMOS 24, using the maximum likelihood estimator.
Findings: Before model estimation, univariate normality was confirmed, with skewness and kurtosis values for all items falling within ±2. The exploratory factor analysis and subsequent confirmatory factor analysis supported a robust, two-factor measurement model comprising 6 items: Disaster experience and its consequences, and preventive and coping measures. All standardized factor loadings were statistically significant (p<0.001). The measurement model demonstrated an optimal fit to the empirical data: χ²=14.80, χ²/degree of freedom=1.85, RMSEA=0.065, NFI=0.96, comparative fit index=0.98, IFI=0.98, goodness of fit index=0.97, and adjusted goodness of fit index=0.92. Reliability assessment showed high internal consistency for the total scale, with Cronbach’s alpha (α=0.85) and McDonald’s omega (ω=0.86). Convergent validity and construct reliability were established for both dimensions: Disaster experience and its consequences (average variance extracted=0.526, composite reliability=0.788) and Preventive and coping measures (average variance extracted= 0.516, composite reliability=0.780).
Conclusion: The Persian six-item Disaster Risk Management and Psychosocial Outcomes Scale demonstrates satisfactory validity, reliability, and factorial structure for assessing disaster-related experiences and pre- and post-disaster coping actions among Iranian firefighters.
