THE CHINESE GENERAL HEALTH QUESTIONNAIRE IN A PSYCHIATRIC SETTING - THE DEVELOPMENT OF THE CHINESE SCALED VERSION

The development of the Chinese scaled GHQ-20 was based on the factor analysis of the item responses of 150 general psychiatric patients with the Chinese GHQ-60. The five subscales assessing the symptom areas of dysphoric functioning, health concern, anxious coping, sleep problems, and suicidal ideas were found to discriminate significantly the sample of patients from another sample of 653 nonpatients. As a scale, the Chinese GHQ-20 was also found to be comparable to the full Chinese GHQ-60 in screening for individuals who might benefit from psychiatric consultation. The implications for its use as a refined instrument to monitor therapeutic change of patients in different symptom areas are discussed.
