The purpose of this study was to evaluate the relationship between a self-report (explicit) measure of interpersonal difficulties – the Inventory of Interpersonal Problems (IIP; Horowitz et al., 2000 ) – and the Rorschach, which includes implicit measures of self-perception and interpersonal relatedness. Seventeen a priori predictions were made regarding the face-valid associations (i.e., correlations) between the IIP and selected Rorschach variables. A sample of 62 undergraduates were administered the Rorschach and IIP. Their IIP scores were slightly higher than the normative sample reported by Horowitz et al. (1988) . Nonetheless, seven predicted relationships were statistically significant and included the following Rorschach variables: Intellectualization Index, AG, FM, S, T, Y, and MOR. These results remained significant when they were controlled for response productivity. Five of the predicted correlations approached statistical significance and included the following Rorschach variables: T, Food, Egocentricity Index, and M%. Most of the correlations were observed in the submissive hemisphere of the interpersonal circumplex. Nonsignificant results were partially explained to be the result of “heteromethod inversion” ( Bornstein, 2002 ) in which defensiveness in admitting difficulties in some interpersonal domains leads to apparent inconsistencies in explicit and implicit measures of a given trait or quality.
