The current study evaluated the comparability of Minnesota Multiphasic Personality Inventory–3 (MMPI-3) scale scores derived from the 335-item MMPI-3 to MMPI-3 scale scores derived from the 433-item MMPI-2 restructured form–expanded version (MMPI-2-RF-EX), an enhanced version of the MMPI-2-RF that was used to develop and validate the MMPI-3. To that end, we examined data from 192 college undergraduates who completed both the MMPI-3 and MMPI-2-RF-EX 1 week apart using a counterbalanced design. Across versions, mean T-scores and standard deviations, estimates of internal consistency, and standard error of measurement values, were highly similar, indicating no clinically meaningful differences across versions. We also compared between-version test–retest comparability values with within-version values calculated using a sample of undergraduates (N = 318) who completed the MMPI-2-RF-EX twice over the same time interval, finding only marginal differences across the two samples. Finally, we computed column-vector correlations between MMPI-3 scores from both versions and several criterion measures, where results reflected no effect of test version on external validity. Overall, we determined that scale scores derived from either booklet are psychometrically interchangeable, indicating that MMPI-3 scale scores obtained from an administration of the MMPI-2-RF-EX can be applied when using the 335-item MMPI-3.

检查源自 MMPI-3 和 MMPI-2-RF-EX 的 MMPI-3 量表分数的心理测量等效性

目前的研究评估了源自 335 项 MMPI-3 的明尼苏达多相人格量表(MMPI-3)量表分数与源自 433 项 MMPI-2 重组形式扩展版本的 MMPI-3 量表分数的可比性( MMPI-2-RF-EX),MMPI-2-RF 的增强版本,用于开发和验证 MMPI-3。为此,我们检查了 192 名大学本科生的数据,他们使用平衡设计分别完成了 MMPI-3 和 MMPI-2-RF-EX 1 周。在不同版本中,平均 T 值和标准差、内部一致性估计和测量值的标准误差高度相似,表明不同版本之间没有临床意义的差异。我们还将版本间重测可比性值与使用本科生样本计算的版本内值进行了比较(N = 318)在同一时间间隔内完成了 MMPI-2-RF-EX 两次,发现两个样本之间仅存在边际差异。最后,我们计算了两个版本的 MMPI-3 分数和几个标准度量之间的列向量相关性,其中结果反映了测试版本对外部有效性没有影响。总体而言,我们确定从任一小册子得出的量表分数在心理测量上是可互换的,这表明在使用 335 项 MMPI-3 时,可以应用从管理 MMPI-2-RF-EX 获得的 MMPI-3 量表分数。
