On the Validity of Hypotheses Derived from the Rorschach: V. The Relationship between Form Level and Ego Strength

Abstract

Although Rorschach interpreted form level as a perceptual and conceptual aspect of intelligence, Beck and the more current meaning assigned to form level relates these functions to ego strength. F+%, therefore, has come to be regarded as a measure of ego strength. The research examining the validity of this assumption was reviewed and Beck's hypothesis was seen to be supported. The research supports the clinical use of F+% as a measure of ego strength, but further research might help clarify what actual psychological processes are involved in the creation of responses of good form.
