最近的两项荟萃分析为儿童和青少年心理治疗效果提供了证据。然而，批评者指出，这种荟萃分析往往包括研究方法的缺陷，可能会使他们的结果无效。在本研究中，我们探讨了最广泛的儿童/青少年荟萃分析的结果是否可能受到这些方法变量的影响，重点是内部效度和外部效度因素。这些因素加起来占实质性因素（例如，治疗类型、年龄）。这表明，相对于这些治疗和儿童特征变量，方法学因素对荟萃分析结果有实质性的影响，尽管影响较小。一般来说，增加实验的严谨性与更大的效应量有关;这与方法学薄弱的研究导致高估治疗效果的假设相矛盾。在有效性因素和结果预测因子之间没有发现显著的交互关系;这表明在以前的荟萃分析中注意到的结果和各种变量之间的关系没有被这里测试的有效性因素所扭曲。
Two recent meta-analyses have generated evidence for child and adolescent psychotherapy effects. However, critics note that such meta-analyses often include studies with methodological shortcomings which might invalidate their results. In the present study, we explored whether the results of the most extensive child/adolescent meta-analysis might have been influenced by such methodological variables, focusing on internal validity and external validity factors. Together, these factors accounted for two-thirds as much variance as the substantive factors (e.g., type of therapy, age) in the original metaanalysis. This suggests that relative to these therapy and child-characteristic variables, methodological factors have a substantial, though smaller, impact on metaanalysis results. In general, increased experimental rigor was related to larger effect sizes; this argues against the hypothesis that methodologically weak studies have led to an overestimate of therapy effects. No significant interactive relations were found between validity factors and predictors of outcome; this suggests that the relations noted in previous metaanalyses between outcome and various variables were notdistorted by the validity factors tested here.
