A comparison of Rorschach developmental level and form-level systems as indicators of psychosis.

Psychotic and nonpsychotic psychiatric inpatients were tested on the Rorschach. "Reality-testing" was measured by four form-level scoring systems designed by Beck, Mayman, Becker, and Wilensky. The psychotic subjects were dichotomized on three diagnostic dimensions: schizophrenia, paranoia, and premorbid social adjustment. No significant differences were found for the Beck system. With the other systems, psychotics showed significantly poorer reality testing than nonpsychotics. No differences were found for the schizophrenic and paranoid dimensions. The Phillips premorbid adjustment score was negatively correlated with all four measures of "reality-testing." The conclusion drawn was that Rorschach measures of "reality testing" are associated with psychotic and poor premorbid functioning, but do not differentiate schizophrenic from nonschizophrenic psychotics or paranoid schizophrenics from nonparanoid schizophrenics.
