Rorschach Comprehensive System Data for a Sample of 100 Adult Nonpatients from the Belgian French-Speaking Community

This article presents normative data for the Rorschach Comprehensive System (CS) on 100 adult nonpatients from the Belgian French-speaking community. We compare our Belgian sample to a French one (Sultan et al., 2004), data of Exner's (Exner & Erdberg, 2005) and a Californian sample (Shaffer, Erdberg, & Haroian, 1999). Each sample's specific characteristics are explored, as well as findings provided by sample-specific comparison. Exner's data, ultimate normative reference for th CS, differ significantly from the three other samples for many variables. Cultural factors, examiner's level of experience, as well as participants' selection and recruitment, presumably flow into calculated differences between the four samples. Our findings indicate the necessity for consulting normative data for different communities, as well as the indispensabilityof examiners' familiarity with the CS, in order to provide reliable clinical informations.
