All scales in the TipX Atlas inventory have undergone validity and reliability testing before being made available. TipX While the validity and reliability studies of some scales in the system have been completed and published, the studies and publication processes of others are ongoing. As the publication of scales is completed and accepted for publication, they will continue to be shared with you. To avoid affecting the publication process of scales that have not yet completed their publication process, the sharing of validity and reliability information is postponed.
TipX Furthermore, at least two experts in the field provide feedback on all existing scales, and the objectivity of expert opinions is ensured by reviewing them with three separate artificial intelligence models, providing a higher level of suitability check. Below is a brief overview of the psychometric information for scales whose validity and reliability have been published.

TipX 4 (11), 160-181 DOI: http://dx.doi.org/10.16990/SOBIDER.3478 TipX The Cronbach's Alpha value of the scale is 0,901; the Guttman reliability coefficient is 0,915; and the Spearman Brown coefficient is 0,91. The scale has a statistically significant item discrimination feature at the p < 0,001 level; and a statistically significant item total correlation at the p <0.001 level. As a result of the AFA (exploratory factor analysis), the scale, which has a sample adequacy of KMO= 0,844, explains % 73,899 of the total variance with a total factor loading of 19,952 obtained in 9 factors. The scale model was also tested with DFA (Confirmatory Factor Analysis) and the model's fit indicators, tested with p value=0,000; χ2/df=1,41; RMSEA=0,045, SRMR=0,028, NFI=0,849; CFI =0,949; GFI=0,875 and AGFI=0,836, were found to be within acceptable reference ranges. As a result of the DFA, the standardized regression weights of the Enneagram Personality Scale are at the lowest level of 0,640; at the highest level of 0,909, and it was determined that all items were statistically significant at the p <0,001 level; and that the variance (lowest 0,236; highest 0,562) and covariance values were statistically significant at the p <0,001 level for all items. The AFA and DFA fit measures of the Enneagram Personality Scale were evaluated according to the reference ranges given in the literature, and it was determined that the model used was a statistically appropriate model.

TipX (See: YÖK National Thesis Center) TipX The Cronbach's Alpha value of the scale is 0.897; the Guttman reliability coefficient is 0.911; and the Spearman Brown coefficient is 0.912. The scale has a significant item discrimination feature with p < 0.001; and a significant item-total correlation with p < 0.001. As a result of AFA (exploratory factor analysis), the scale, which has a KMO = 0.850 sample adequacy, explains a total of 74.679% of the total variance with a total of 20.164 factor loadings in 9 factors. In the DFA (confirmatory factor analysis) test of the scale model, the p-value is 0.000; χ2/df = TipX 1.662

It was determined that the model's fit indicators, tested with these values, are within acceptable reference ranges. As a result of DFA, the standardized regression weights of the scale are at the lowest level of 0.577 and the highest level of 0.850, and it was determined that all items are statistically significant with p < 0.001; and that the variance (lowest 0.111; highest 0, TipX 498 TipXTipX ) and covariance values are statistically significant with p < 0.001 for all items.
