Do empirically derived MMPI criteria accurately diagnose schizophrenia in older hospitalized patients compared to a standardized structured interview?
Do empirically derived MMPI criteria accurately diagnose schizophrenia in older hospitalized patients compared to a standardized structured interview?
Empirically derived MMPI criteria for schizophrenia showed poor generalizability in an older sample of hospitalized patients.
Answers are grounded in this paper and cite their sources.
Empirically derived MMPI criteria may lack applicability in older hospitalized patients; challenges generalizability and supports age-specific validation research.
Assessed the generalizability of empirically derived MMPI criteria for the diagnosis of schizophrenia with an older sample of hospitalized patients (N = 65). The criterion diagnosis was established through the use of a standarized structured interview and a diagnostic system for schizophrenia based on the use of discriminant function analysis. Results were quite disappointing because only 22% of the sample obtained an MMPI profile that fit the above criteria.
