我们用《美国精神障碍诊断与统计手册 》 （ 第4版）的结构化临床问卷 （即人格障碍诊断问卷SCID）对七百名精神病科的门诊病人进行了访问并让他们亲自填写了问卷，其内容是关于他们是否之前曾被医疗专业人员诊断为双相或狂躁—抑郁障碍。
Seven hundred psychiatric outpatients were interviewed with the Structured Clinical Interview for DSM-IV (SCID) and completed a self-administered questionnaire that asked whether they had been previously diagnosed by a health-care professional with bipolar or manic-depressive disorder.
