本荟萃分析旨在确定德国儿童和青少年中情绪和行为障碍的总体患病率，患病率估计对所采用方法的依赖性以及潜在的长期趋势。方法采用随机效应模型对初步研究进行meta分析。主要研究效应的平均估计值使用精度加权法平均，随后使用层次回归和（协）方差分析进行敏感性分析。结果纳入的33项研究的精度加权平均主要研究患病率为M=17.6%。效应大小主要取决于所采用的案例定义，应用问卷标准的研究平均显示较低的主要研究效应。研究效度与主要研究效果呈负相关。半个世纪的研究表明，大约六分之一的儿童表现出情绪或行为障碍的迹象，关于经期影响的结论并不可靠。
Background This meta-analysis aimed to determine the overall prevalence of emotional and behavioural disorders among children and adolescents in Germany, the dependence of prevalence estimates upon the methods employed and potential secular trends.Methods Primary studies were subjected to meta-analytical analyses using a random effects model. Mean estimates of primary study effects were averaged using the precision-weighted method and were subsequently subjected to sensitivity analyses using hierarchical regression and (co-)variance analyses.Results The precision-weighted average primary study prevalence for the 33 studies included was M=17.6%. The effect size primarily depended on the case definition employed, with studies applying questionnaire criteria showing, on average, lower primary study effects. Moreover, a negative relationship was found between study validity and primary study effect.Conclusion Half a century of research efforts indicate that approximately every sixth child shows signs of emotional or behavioural disorders, and conclusions regarding period effects are not robust.
