Introduction: Impulsivity means acting with the least thought towards future behaviors or acting based on thoughts that are not the best option for a person or others. This study was conducted to investigate psychometric properties of the Persian version of the Impulsive Behavior Scale (IBS) of Barratt on pre-hospital personnel of Shiraz University of Medical Sciences in 2023.
Materials and Methods: This methodological study was conducted 18 pre-hospital emergency centers of Shiraz University of Medical Sciences during 2022-2023. In this study, the Persian version of the IBS has been used. Face and content validity of the scale in this study was confirmed using qualitative and quantitative methods, and construct validity was confirmed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The reliability of the questionnaire was calculated by Cronbach's alpha and intra-class correlation coefficient (ICC) for each field and the scale.
Results: The IBS had three unplanned, motor and attentional subscales with 23 items and the varimax rotation showed variance of 52.06%. In CFA, root mean square error of approximation (RMSEA) was equal to 0.093 and normalized fit index (NFI), comparative fit index (CFI), goodness of fit (GFI) and incremental fit index (IFI) were higher than 0.9. Cronbach's alpha coefficient in the scale was 0.85%, and the intra-subject correlation coefficient (ICC) was 0.84%.
Conclusion: The study results showed that the scale for pre-hospital personnel had the required validity and reliability, and it can be used for the impulsive behavior in pre-hospital personnel.
