用标准化的方法和工具研究了两所基层综合性医院内科门诊病人中符合诊断标准的心理障碍的患病率，以及心理障碍对病人的影响及内科医生的识别和处理能力。研究方法为两步筛查诊断法，一般健康问卷（ＧＨＱ－１２）作为筛查工具，复合式国际诊断检查普通医疗版（ＣＩＤＩ－ＰＨＣ）为病例诊断工具。共随机筛查了１６７３例病人，其中５７６例完成了诊断性检查。符合国际疾病分类第１０版标准的心理障碍的加权总患病率为９．７％，其中重性抑郁的患病率最高（４．０％）。内科医生对心理障碍的识别率为１５．９％。研究结果显示，在内科门诊病人中心理障碍常见。心理障碍使病人的自我健康评价过低并导致明显的社会功能缺陷。心理障碍病人倾向于将心理问题归因于躯体疾病，没有得到恰当的诊断和治疗。
The standardized methods and tools were used to study the prevalence of diagnostic criteria-compliant psychiatric disorders in two outpatient general hospital outpatient settings as well as the impact of psychological disorders on patients and physicians’ ability to recognize and process them. Methods Two-step screening diagnostic method, general health questionnaire (GHQ-12) as a screening tool, and composite international diagnostic tests for general medical diagnosis (CIDI-PHC) were used as case diagnostic tools. A total of 1673 patients were randomly screened, 576 of whom completed the diagnostic test. The weighted total prevalence of mental disorders that met the 10th edition of the International Classification of Diseases was 9.7%, with the highest prevalence of major depression (4.0%). The physician’s recognition rate of psychological disorders was 15.9%. The results show that psychiatric disorders are common in medical outpatients. Psychological disorders make the patient’s self-health rating too low and lead to significant social dysfunction. Patients with mental disorders tend to attribute psychological problems to physical illness and are not properly diagnosed and treated.
