EFFECTS OF INDIVIDUAL VERSUS GROUP TEST ADMINISTRATION ON RORSCHACH ORAL DEPENDENCY SCORES

Two studies involving a total of 200 participants examined the effect of individual versus group test administration on Rorschach Oral Depen dency (ROD) scores. In Study 1, 60 college students completed the ROD scale via a group administration, and 60 students completed individual Rorschach protocols from which ROD scores were derived. Analyses reve aled no differences in ROD means and standard deviations and no differ ences in the form of the ROD score distributions (i.e., skewness and k urtosis) as a function of mode of test administration. Virtually ident ical results were obtained in Study 2 (N = 80), where a within-partici pants design was used in lieu of the between-participants design of St udy 1. Implications of these findings for the construct validity of th e ROD scale are discussed.
