Psychiatric Morbidity in Chinese Patients with Chronic Hepatitis B Infection in a Local Infectious Disease Clinic.

Objective: To determine the prevalence of psychiatric morbidity, identify correlates of psychiatric morbidities, and evaluate the effectiveness of the 12-item General Health Questionnaire as a screening tool for psychiatric morbidity in Chinese patients infected with chronic hepatitis B. Methods: This cross-sectional study was conducted in a local public specialist outpatient infectious disease clinic from October 2008 to June 2009, in which a total of 160 patients were randomly selected. Psychiatric diagnoses were established by using the Chinese-Bilingual Structured Clinical Interview for the DSM-IV (Axis I Disorders). Scores for the General Health Questionnaire were compared against the psychiatric diagnoses. Results: Among 149 patients, the respective point prevalence of overall psychiatric disorders, depressive disorders, and anxiety disorders was 32%, 16%, and 14%. A family history of psychiatric disorder and absence of knowledge of mode of hepatitis B virus transmission were identified as being associated with current psychiatric disorders, current depressive disorders, and current anxiety disorders. Absence of a confidant was an independent factor for current depressive disorders and use of herbal medicine in the previous month was an independent factor for current anxiety disorders. Conclusion: Psychiatric disorders are common in Chinese patients with chronic hepatitis B. Identifying associated factors and using the General Health Questionnaire as a screening tool are useful for identifying patients with psychiatric disorders in an infectious disease clinic.
