效度概化是通过元分析技术对普遍化的预测效度的估计。元分析是研究效度概化问题的技术,是对具有“预测因子.效标”特征的相关数据进行定量综合的方法。效度概化促进了预测因子与效标之间关系的理论研究和应用研究,是应用心理学领域近30年(1977-2007)来最重要的进展之一。30年来的效度概化研究表明,认知能力测验、知识和技能测验、人格测验、结构化面试和评价中心技术等的预测效度具有鲁棒性、对应性和联合增值性。
Validity generalization (VG) is one of the most useful methodologies to estimate the effect sizes of predictor-criterion relationships based on the techniques of meta-analysis. One of the most important advances on applied psychology in recent 30 years (1977-2007) is the work on validity generalization. This article reviewed on the achievements in VG. Hunter-Schmidt's meta-analytic procedures made it possible to draw clearer and more consistent conclusions from the body of literature across independent studies about the predictive validity of predictors. Robustness, correspondence and increment quality of the predictive validities of abilities, factors of personality, interviews, and assessment centers had been found.
