Preliminary analyzes were performed to verify the relevance and validity of the study data and the appropriateness of the exploratory and confirmatory factor analysis. The results confirmed that the data distribution is in the normal level, and the stability value of the expressions by calculating Cronbach alpha ranged between (.759 to .795) they are high values. The results of; the correlation matrix, the Kaiser-Meier-Olkin test, and the Bartlett test showed the suitability of the methods used. Then, exploratory factor analysis was adopted. To verify the formative honesty, extract the factors and categorize them according to the degree of their saturation and their relationship with other factors, as it was found that there are four axes of the scale whose latent root is more than the correct one. Each phrase with the axis to which it belongs was statistically significant at the level (0.01), thus confirming the formative validity of the scale.
