The psychiatric morbidity among 718 Chinese primary school children from a lower middle social class area in Hong Kong was studied, using a two-stage design. The screening procedures included two parts, a multi-component scale and a battery of probing questions. The screening procedures achieved an overall sensitivity of 75% and a specificity of 97%. The findings on prevalence were: (i) a total prevalence of all definite psychiatric cases of 16.3%; (ii) prevalence according to diagnostic categories: emotional disorder, 8.8%; conduct disorder, 2.0%; mixed disturbance of emotion and conduct, 3.0%; hyperkinetic syndrome, 1.0%; hyperkinetic conduct disorder, 1.0%; and Gilles de la Tourette's syndrome, 0.4%; (iii) boys 2.7 times more affected than girls; (iv) emotional disorder much more common than conduct disorder, even in boys; and (v) the prevalence of borderline cases was 19.5%. The mean duration of morbidity for all definite cases was 41.7 months. About half of all definite cases were seriously impaired in one or more areas of functioning and the other half moderately impaired. These results were compared with findings obtained from studies done in other countries.
采用两阶段设计，对来自香港一个社会经济地位中下地区的718名中国小学生的精神疾病发病率进行了研究。筛查程序包括两部分，一个多成分量表和一系列探究性问题。筛查程序的总体敏感性为75%，特异性为97%。患病率调查结果如下：(i)所有确诊精神疾病病例的总患病率为16.3%；(ii)按诊断类别划分的患病率：情绪障碍8.8%；品行障碍2.0%；情绪和品行混合障碍3.0%；多动综合征1.0%；多动品行障碍1.0%；以及抽动秽语综合征0.4%；(iii)男孩受影响的几率是女孩的2.7倍；(iv)即使在男孩中，情绪障碍也比品行障碍更为常见；(v)边缘病例的患病率为19.5%。所有确诊病例的平均发病时长为41.7个月。约一半的确诊病例在一个或多个功能领域受到严重损害，另一半受到中度损害。这些结果与其他国家的研究结果进行了比较。
