Objective: The aim of this study was to measure the prevalence of psychiatric morbidity following miscarriage among Chinese women in Hong Kong. The utility of two simple and brief self-report questionnaires in screening psychiatric morbidity after miscarriage was also evaluated. Methods: 282 subjects completed the 30-item General Health Questionnaire (GHQ), the Edinburgh Postnatal Depression Scale (EPDS) and the Beck Depression Inventory (BDI) six weeks after miscarriage. They were then assessed with the Structured Clinical Interview for DSM-III -R (SCID) to establish psychiatric diagnoses. The criterion validity of GHQ and EPDS were tested against this yardstick diagnosis, and the concurrent validity against the BDI scores. The internal consistency of the scales was measured by Cronbach's a coefficient. Results: 29 subjccts(10.3%) met the DSM-III-R criteria for major depression. Both GHQ and EPDS had good sensitivity and specificity in screening for psychiatric morbidity after miscarriage. The concurrent validity and the internal consistency of both scales were satisfactory. Conclusions: Chinese women in Hong Kong have a lower rate of psychiatric morbidity after a miscarriage. The EPDS and GHQ will be particularly useful for non-psychiatric medical personal in screening for depressive illness after miscarriage.
