Previous studies have suggested an association between chronic middle ear disorders due to secretory otitis media and adverse effects on auditory, educational and psychological development in children. Experimental design of such studies has often been poor. In this study, attempts were made to control extraneous variables more rigorously, using matched pairs. A group of children (n = 10) without current hearing problems but with a history of recurrent early secretory otitis media, aged 7-11 yrs, were compared on auditory, educational and psychological measures with a matched group of children with no history of otitis media. The results indicated weak but distinct differences between the two groups on the educational and psychological measures in favour of the control group. The implications for medical and educational services are outlined.
以往研究表明,分泌性中耳炎所致慢性中耳疾病与儿童听觉、教育及心理发育的不良影响之间存在关联。此类研究的实验设计往往欠佳。在本研究中,尝试通过配对更严格地控制无关变量。选取一组7至11岁、目前无听力问题但有复发性早期分泌性中耳炎病史的儿童(n = 10),在听觉、教育及心理指标方面与一组无中耳炎病史的配对儿童进行比较。结果表明,两组在教育及心理指标上存在微弱但明显的差异,对照组表现更佳。文中概述了对医疗及教育服务的启示。
