In a two-stage epidemiological study to determine the prevalence and pattern of psychiatric morbidity in an urban primary care setting in Nigeria, the 12-item General Health Questionnaire (GHQ) was used to screen 787 clinic attenders while a modified version of a structured clinical interview designed for epidemiological surveys, the Composite International Diagnostic Interview (CIDI), was used to interview 214 subjects in the second stage. In order to improve case detection, selection for the second-stage was by stratified sampling in which patients were selected using a low score threshold and a revised scoring method devised to improve screening ability. A weighted prevalence for specific DSM-IIIR diagnoses of 27.8 per cent was obtained. Another 7.3 per cent of the clinic attenders suffered from non-specific disorders principally with mixed affective symptomatology. The association of demographic features to the disorders was examined; while a number of the associations followed previously reported trends, a few were unusual, possibly reflecting the cultural differences in the various study environments.
在一项两阶段的流行病学研究中，为确定尼日利亚城市初级保健机构中精神疾病的患病率和模式，采用12项一般健康问卷（GHQ）对787名门诊患者进行筛查，而在第二阶段，使用为流行病学调查设计的结构化临床访谈的修改版——综合国际诊断访谈（CIDI）对214名受试者进行访谈。为了提高病例检出率，第二阶段采用分层抽样选择患者，其中使用低分数阈值和为提高筛查能力而设计的修订评分方法来选择患者。获得特定DSM-IIIR诊断的加权患病率为27.8%。另外7.3%的门诊患者患有主要伴有混合情感症状的非特异性疾病。研究了人口统计学特征与疾病的关联；虽然一些关联遵循先前报道的趋势，但有一些不寻常，可能反映了不同研究环境中的文化差异。
