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.
