model for identifying criminals based on biological

The present study was designed and implemented in terms of type and method of descriptive-analytical and in terms of purpose and practical nature and in terms of data collection, documentary-survey and using qualitative and quantitative approaches.For a quantitative approach, the questionnaire includes 217 people, The validity of the questionnaire was confirmed by experts and its reliability was obtained by calculating the Cronbach's alpha coefficient of 70%. Descriptive statistics and inferential statistics were used to analyze the data. Findings from t-test showed that the value of t-statistic in all four dimensions was greater than 1.96, which indicates the significance of the test and the effectiveness of each dimension. All dimensions and components based on K-S test had an alpha value of more than 70% and the data distribution was normal. To confirm the predicted structures after the first-order factor analysis and to model the equations, confirmatory factor analysis, etc, which, the results indicate that the indicators are desirable and the items are in line with the theoretical structure.Based on the results, the respondents had the most effective dimension in identifying criminals, the technical dimension with an average of 4.53 out of 5 and the least effective dimension of the management dimension with an average of 4.26 out of 5. mean 4.4 and standard deviation 0.6. According to the findings, the effect of the set of dimensions was 4.41 out of 5 with a median of 4.5 and a standard deviation of 0.4.
