一个元分析到一般心理能力（GMA）措施的操作效度在德国提出。考虑到美国和欧洲教育体系的差异，该荟萃分析解决了美国和欧洲荟萃分析的结果是否可以推广到德国的问题。德国教育体系的高度分化有望增强申请人群体的同质性，从而导致预测分数的低水平可变性，从而降低了观察到的gmperformance关系。我们的分析基于54篇独立的德国文章和未发表的报告。结果表明，培训成功的操作效度p= 0.467 (k=90， N=11,969)，工作绩效的操作效度p= 0.534 （k=9， N=746）。调节变量分析表明，工作复杂程度和发表年份是相关的调节变量，较低的工作复杂程度和较老的研究具有较高的操作效度。研究结果表明，德国的总体操作有效性与美国或其他欧洲国家的研究结果相当。然而，与美国或欧洲的元分析相比，德国的培训成功操作GMA效度略低。
A meta-analysis into the operational validity of general mental ability (GMA) measures in Germany is presented. The meta-analysis addresses the question whether findings of US and European meta-analyses are generalizable to Germany given the differences in the education systems of these countries. The high level of differentiation in the German educational system is expected to enhance the homogeneity of applicant pools resulting in a low level of variability in predictor scores which reduces the observed GMAperformance relationships. Our analysis is based on 54 independent German articles and unpublished reports. Results indicated an operational validity of p=.467 for training success (k=90; N=11,969) and p=.534 for job performance (k=9; N=746). Moderator analyses showed that job complexity and the year of publication are relevant moderator variables, with lower job complexity levels and older studies being associated with higher operational validities. Findings suggest that overall German operational validities are comparable with findings in the United States or other European countries. However, for training success operational GMA validities are slightly lower in Germany compared with US or European meta-analyses.
