Concurrent validity of scores of the Hemispheric Mode Indicator (a measure of cognitive hemispheric dominance) was assessed by product-moment correlation with scores for the Human Information Processing Survey (a more-studied measure of hemispheric dominance) for 27 nurse-anesthetist students and 94 medical students (r = .61 and .69, respectively). For 70 of the medical students, test-retest stability was only fair (r = .74). For 525 undergraduates and 156 medical students, although alpha coefficients were .78 and .84, respectively, consideration of interitem correlations and principal components analyses indicated that some of the Hemispheric Mode Indicator's items are unsuitable as worded and that the 32 items probably represent more than one underlying latent variable.
通过与人类信息处理调查（一种研究更为深入的认知半球优势测量方法）的分数进行积差相关分析，对半球模式指标（一种认知半球优势的测量方法）分数的同时效度进行了评估，该调查涉及27名麻醉护士专业学生和94名医科学生（相关系数分别为0.61和0.69）。对于70名医科学生，重测稳定性一般（相关系数为0.74）。对于525名本科生和156名医科学生，尽管阿尔法系数分别为0.78和0.84，但对项目间相关性的考量以及主成分分析表明，半球模式指标的一些项目按措辞来说并不合适，且这32个项目可能代表不止一个潜在的潜在变量。
