Utility of MMPI indices of schizophrenia with adolescents

Assessed the utility of empirically derived MMPI criteria for the diagnosis of schizophrenia with a sample of hospitalized adolescent patients (N = 89). The criterion diagnosis was established through the use of a standardized structured interview and a diagnostic system for schizophrenia based on the use of discriminant function analysis. Results were quite disappointing because only 23% of the sample obtained an MMPI profile that fit the above criteria.
