title: Concordance between telephone survey classification and face-to-face structured clinical interview in the diagnosis of generalized anxiety disorder in Hong Kong.
abstract: Telephone surveys of estimating mental disorders have been found to generate comparable findings to large-scale community surveys but the concordance between telephone instruments and clinical interviews is rarely examined. In this study, 100 Chinese respondents who had taken part in a telephone-based population survey of generalized anxiety disorder (GAD) in Hong Kong were administered the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) by clinical interviewers. The discriminability and predictive indicators of the telephone survey instrument were assessed using receiver operating characteristic analysis. Results showed that the telephone survey instrument identified individuals with a positive SCID diagnosis of GAD better than those without. Although its individual questions performed well in identifying the endorsement of the corresponding core SCID criterion of GAD, further studies are needed to find out the optimal combination of questions in the telephone instrument for identifying GAD in community surveys.
