The 30-item General Health Questionnaire (GHQ), the 24-item Self-Reporting Questionnaire (SRQ), and a Chinese version of the Minnesota Multiphasic Personality Inventory (MMPI) were administered to 225 English-speaking Chinese. The GHQ was found to have high internal consistency as a scale and to assess 5 dimensions of psychopathology: anxiety, inadequate coping, depression, insomnia, and social dysfunctioning. As a brief screening instrument, it correlated 0.49 with the SRQ. In the 'case-non-case' classification, it yielded a concordance rate of above 75% with the SRQ. Using the MMPI modal profiles derived from classification research as criterion measures, sensitivity, specificity and correct classification rates were above 70%. Implications for future research with the GHQ are discussed.
