The dynamics of assessment center validity: Results of a 7-year study.
研究了评价中心（包括小组讨论和分析/陈述练习）在7年内预测679名大学毕业生职业晋升（以平均薪资增长衡量）的效度变化，发现人际有效性维度在几年后才开始有效，而韧性维度始终有效且随时间增强。
We investigated tempora1 trends in the validity of an assessment center consisting of a group discussion and an analysis/presentation exercise, for predicting career advancement as measured by average salary growth over a 7-year period, for a sample of 679 academic graduates.The validity of the overall assessment rating (OAR) for persons with tenure of 7 years, corrected for initial differences in starting salaries, restriction in range, was .39.There was a considerable time variation in the validity of both the OAR and assessment center dimensions.In accordance with findings hom research in managerial effectiveness and development, the dimension interpersonal effectiveness only became valid after a number of years, while the dimension fknness was predictive in the whole period and increased in time.For comparison, validity trends for two types of interviews and a mental test were also studied.
