Assessing object representations as a continuous variable: a modification of the concept of the object on the...

Current methods for assessing the quality of internalized object representations have not provided a continuous variable that simultaneously includes both an accuracy and a maturity component. A modification of Blatt, Brooks, Brenneis, and Schimek's (1976) Concept of the Object on the Rorschach scale that would combine the two components by weighting the quality of each response according to its form level was proposed. Initial discriminant and convergent validity of this modification was checked through correlations and multiple regression analyses using behavioral, diagnostic, and demographic data from 84 adolescent inpatients as dependent variables. Results indicate the modified score was directly related to measures of peer relatedness, intelligence, psychological health, and reality testing, and indirectly related to measures of psychosis and hostile, unmanageable behavior. The results support the utility of the modification for providing a continuous score that assesses both developmental maturity and accuracy, the two dimensions on which the concept of object representation is based.
