Abstract

This report presents Minnesota Multiphasic Personality Inventory (MMPI) findings from the Minnesota Study of Twins Reared Apart. Data from 65 unique pairs of monozygotic twins reared apart (MZA) and 54 unique pairs of dizygotic twins reared apart (DZA) were analyzed. As in other results from this sample, MZA twins evidenced substantial similarity, highlighting the influence of shared genes. Biometric modeling yielded estimates of heritability for the MMPI's standard validity and clinical scales and for the Wiggins content scales ranging from .26 to .62 (M = .44), echoing previous findings from the twin and adoption literature on personality. The pattern of MZA and DZA correlations suggested nonadditive genetic effects for 3 MMPI scales. Multivariate profile analyses also suggested genetic influence on both profile elevation and shape.

摘要

本报告展示了明尼苏达分开抚养双胞胎研究中的明尼苏达多相人格量表（MMPI）研究结果。分析了来自65对独特的分开抚养的同卵双胞胎（MZA）和54对独特的分开抚养的异卵双胞胎（DZA）的数据。与该样本的其他结果一样，MZA双胞胎表现出显著的相似性，突出了共享基因的影响。生物统计学建模得出了MMPI标准效度和临床量表以及威金斯内容量表的遗传力估计值，范围从0.26到0.62（M = 0.44），这与双胞胎和收养文献中先前关于人格的研究结果相呼应。MZA和DZA相关性模式表明，3个MMPI量表存在非加性遗传效应。多变量剖面图分析还表明，遗传因素对剖面图的高度和形状均有影响。
