Factor analytic solutions for raw scores and corresponding percentage conversion scores derived from Rorschach and Hand Test variables were directly compared. Number of factors, total and individual communalities, and test overlap were sufficiently different to question either approach as preferable for summarizing interrelationships among projective tests and test variables. Most of the substantial loadings tended to be either artifactual, relatively uninformative, or appeared on one factor analysis but not the other.
直接比较了源自罗夏测验和手部测验变量的原始分数以及相应的百分比转换分数的因素分析解决方案。因素数量、总共性和个体共性以及测验重叠差异足够大，以至于难以确定哪种方法更适合总结投射测验和测验变量之间的相互关系。大多数显著载荷往往要么是人为的、信息相对较少，要么出现在一种因素分析中而不出现在另一种因素分析中。
