Methods: Testing was conducted with groups of 20 students. Results: The means of Narcissistic, Antisocial, and Passive Aggressive personality disorders in PDQ +4 were higher in the male group than in the female group. The scores of Avoidance and Obsessive personality disorders at points of 90% and 95% were considerably higher than the cut-off scores of PDQ +4 . Three factors were abstracted by factor analysis. The loading of personality disorders on these three factors deviated significantly from what was originally proposed in the theory of test construction. Conclusion: Cross-cultural factors should be considered when using PDQ +4 in China. The category of personality disorders proposed in the PDQ +4 needs to be further validated.展开更多

We aimed to assess the Chinese (mainland) version of the PDQ-39. Seventy-one subjects with Parkinson's disease (PD) completed the PDQ-39 and the Medical Outcomes Study 36-item Short Form Health Survey (SF-36). All subjects were retested with the PDQ-39 a week later. The united Parkinson's disease rating scale (UPDRS) and the Hoehn and Yahr (H & Y) scale were also used to evaluate the subjects. Reliability was assessed by Cron- bach's α and intra-class correlation coefficient (ICC). Validity was examined in terms of agreement with SF-36, UPDRS, and H & Y scales. The Chinese (mainland) version of the PDQ-39 demonstrated acceptable reliability (Cronbach's α: 0.84-0.88; ICC: 0.56-0.82). The item-total correlations (0.33-0.88) and scaling success rates (77.56%) indicated satisfactory convergent and discriminant validity of the PDQ-39 items. The correlations between related constructs of the PDQ-39 and UPDRS (r=0.44-0.68) and between those of the PDQ-39 and SF-36 (r=(-0.46)-(-0.69)) were all statistically significant (P<0.01). Except for stigma, cognitions, and bodily discomfort, all other dimensions of the PDQ-39 significantly discriminated patients at different H & Y stages indicated by the H & Y scale. Although our observations indicate that some problematic subscales of this version of the PDQ-39 could be improved upon, this study suggests acceptable reliability and validity of the Chinese (mainland) version of the PDQ-39.展开更多
