A general population sample of 1598 Saudi adults completed an online survey.

We applied partial credit model one independent investigate improve characteristics scale replicated our findings with another equal size. Results Minor modifications required address local dependency issues resulted in a good fit CPQ unidimensional both samples. The demonstrated unidimensionality, invariance across personal factors, reliability (PSI 0.78). As expected, scores positively associated disordered behaviors. Conclusions Overall, robust properties after minor that did not change original format. utility accuracy can be enhanced by converting ordinal interval using conversion tables presented this paper.
