Introduction:
The DISC Predictive Scales-4.32 (DPS-4.32) were short-forms of the Diagnostic Interview Schedule for Children-IV (DISC-IV).
Method:
The psychometric properties of DPS-4.32 were tested on two Chinese samples: a clinic sample of 83 children/youths, and a community sample of 541 youths.
Results:
Both Parent and Youth DPS-4.32 exhibited good-to-excellent test-retest reliability. Their screening efficiency was examined respectively against DSM-IV diagnoses of the full-length Parent and Youth DISC-IV. Results indicated large AUCs (Area under Receiver-Operating Characteristic Curve), as well as high sensitivity, specificity, and negative predictive values, supporting the capability of DPS-4.32 to differentiate cases from noncases.
Conclusion:
DPS-4.32 held promise as efficient short-forms of DISC-IV, screening DSM-IV diagnoses. They were also applicable to the Chinese population, demonstrating their cross-cultural applicability.
