A Five-Factor Theory Perspective on the Rorschach

Abstract

Many of the constructs the Rorschach is used to assess are related to personality traits included in the Five-Factor Model, but studies to date have not shown convergence between Rorschach and self-report measures of these traits. This poses a problem for the Rorschach, because recent research on the universality, stability, heritability, and consensual validity of traits demonstrate that self-report measures cannot be dismissed. In an effort to understand these issues, we examine the Rorschach from the perspective of Five-Factor Theory (FFT), a systems model of the person. FFT is compatible with the projective hypothesis, but would generally lead to the expectation that Rorschach signs and self-reports should be correlated. Where they are not, the validity of Rorschach measures of personality traits would need to be confirmed by demonstrations of their heritability, stability, and convergence with observer ratings. The Rorschach may be more useful when interpreted in the context of a global psychodynamic assessment. Clinicians who use the Rorschach should gather the data necessary to test its validity as a measure of personality traits and related constructs, and clinicians and researchers should consider the possible use of Rorschach responses in assessing dynamic processes.
