Toward international normative reference data for the comprehensive system.
We build on the work of all the authors contributing to this Special Supplement by summarizing findings across their samples of data, and we also draw on samples published elsewhere. Using 21 samples of adult data from 17 countries we create a composite set of internationally-based reference means and standard deviations from which we compute T-scores for each sample. Figures illustrate how the scores in each sample are distributed and how the samples compare across variables in eight Rorschach Comprehensive System (CS; Exner, 2003) clusters. The adult samples from around the world are generally quite similar, and thus we encourage clinicians to integrate the composite international reference values into their clinical interpretation of protocols. However, the 31 child and adolescent samples from 5 countries produce unstable and often quite extreme values on many scores. Until the factors contributing to the variability among these samples are more fully understood, we discourage clinicians from using many CS scores to make nomothetic, score-based inferences about psychopathology in children and adolescents.
