The present study investigated evidence for race-related test bias in cognitive measures used in the baseline assessment of the ACTIVE clinical trial. Test bias against African Americans has been documented in both cognitive aging and early life span studies. Despite significant mean performance differences, Multiple Indicators Multiple Causes (MIMIC) models suggested most differences were at the construct level. There was little evidence that specific measures put either group at particular advantage or disadvantage and little evidence of cognitive test bias in this sample. Small group differences in education, cognitive status, and health suggest positive selection may have attenuated possible biases.
本研究调查了美国老年人认知训练计划(ACTIVE)临床试验基线评估中所使用的认知测量方法中与种族相关的测试偏差证据。在认知老化和早期寿命研究中均已记录到针对非裔美国人的测试偏差。尽管平均表现存在显著差异,但多指标多原因(MIMIC)模型表明,大多数差异存在于结构层面。几乎没有证据表明特定测量方法会使任何一组具有特别的优势或劣势,并且在该样本中几乎没有认知测试偏差的证据。教育、认知状态和健康方面的小群体差异表明,正向选择可能减弱了可能存在的偏差。
