title: A community epidemiological survey of generalized anxiety disorder in Hong Kong.
abstract: Generalized anxiety disorder (GAD) is understudied in Asian communities. There were 3,304 Chinese subjects (aged 15-60 years) randomly drawn from the general population of Hong Kong and successfully interviewed. The participation rate was 65.8%. The six-month prevalence of DSM-IV GAD was 4.1%. Over half of the GAD subjects reported palpitations and bowel symptoms. Comorbid depressive mood (65%) and substance use (35%) were common. Forty-one percent of GAD subjects sought help, usually from general practitioners who prescribed tranquilizers after negative physical investigations. Telephone-based surveys have limitations but provide an affordable and destigmatizing alternative to face-to-face surveys for communities with limited mental health resources.
