Validation of the Persian version of Adelaide Driving Self-Efficacy Scale (ADSES)

The purpose of present study was to investigate the factor, predictive and criterion validity and internal consistency of Adelaide Driving Self-efficacy scale (ADSES). In a descriptive-correlation and validation study, 345 people in two studies (147 in the first study and 197 in the second study) were selected through a convenience sampling method from those referring to License Plate Replacement Center in Bojnourd city and completed Adelaide Driving Self-efficacy scale (ADSES). Exploratory and confirmatory factor analysis, discriminate analysis, Pearson `s correlation coefficient, Independent T-Test, and One way Analysis of variance were analyzed using SPSS.16 andAmos.20 software. The results showed that the structure of an agent that explains 76.43% of the variance. Confirmatory factor analysis also confirmed this structure. The internal consistency of the scale was confirmed by Cronbachchr('39')s alpha and split-half coefficient of 0.97. Discriminate analysis based on the history of a driving accident or lack of it, indicates a predictive validity of the scale.There was a positive and significant relationship between age and driving experience with driving self-efficacy. The Item-Response parameters were also at the optimum level. Differences were significant in terms of gender and men had a higher mean. There was no significant difference in terms of educational level. Adelaide Driving Self-efficacy scale (ADSES) seems to have a good validity and reliability and can be used as a precise instrument in this regard.
