Background: Minnesota multiphasic personality inventory-2(MMPI-2) is superior to its predecessor in differential diagnosis. this study was to investigate MMPI-2 profiles of the patients with schizophrenia and depression and to discriminate among two groups.
Methods: The sample consisted of 35 patients with schizophrenia(male 24, female 11), 35 patients with depression(male 18, female 17) diagnosed by the diagnostic and statistical manual of mental disorders(DSM-IV) for schizophrenia & depression at department of neuropsychiatry in WonKwang University from January 2005 to December 2007.
The data from the results were analyzed statistically by t-test and discriminant analysis.
Results: The results were as follows. First, according to t-test results the comparison of schizophrenia patients and depression patients in MMPI-2 among two groups showed significant differences; the validity scales: F, F(P); The clinical scales: D, Pa; The restructured clinical scales: Rcd(dem), RC4, RC6, RC8; The content scales: ANX, DEP, BIZ; The supplementary scales: AGGR, PSYC, Mt, GF, O-H. Second, as a results discriminant analysis, BIZ, D were significant predictors in distinguishing patients with schizophrenia from patients with depression. Third, probability to be discriminated schizophrenia in schizophrenia was 91.4%, probability to be discriminated depression in depression was 85.7%.
Conclusion: Finally, we remind readers that although the MMPI-2 may prove to be useful in the task of differential diagnosis, it should be used only in combination with other patient information.
