摘要

This study investigated the psychodiagnostic abilities of and relationship between indicators of psychiatric disorders. Archival data from 146 adult psychiatric inpatient subjects were used to empirically validate the ability of Minnesota Multiphasic Personality Indicator-II (MMPI-2) code types and Rorschach Inkblot Test indices to accurately classify subjects according to depressive and schizophrenic discharge diagnoses. The predictive or criterion validity of MMPI-2 code types and Rorschach indices were measured by logistic regression analyses, indicating statistical significance of each instrument's individual predictive validity, and the overall diagnostic classification rates, for the two types of diagnoses. The incremental validity of combining the instruments was assessed by hierarchical logistic regression to determine whether the predictive validity and diagnostic efficiency of MMPI-2 code types could be improved by adding Rorschach indices to predict diagnoses of depression and schizophrenia. Chi-square analyses evaluated the independence of the predictor variables to determine the degree of association of the MMPI-2 and Rorschach research instruments as they were used in this study.;Predictive validity results revealed that neither of the MMPI-2 code types investigated (2-7/7-2 for depression, and 8-6/6-8-(7) for schizophrenia) were found to be significant predictors of their respective discharge diagnoses. These code types also had poor diagnostic classification rates. The Rorschach index for depression (DEPI) also failed to demonstrate predictive validity and had a poor classification rate. Only the Rorschach index for schizophrenia (SCZI) was found to be a significant predictor of schizophrenic diagnoses and evidenced a relatively good rate of classification accuracy.;Further, only the Rorschach SCZI demonstrated significant incremental validity over its related MMPI-2 code type in enhancing accurate prediction of diagnosis and improving indices of diagnostic efficiency and classification rates. Finally, the MMPI-2 and Rorschach were found to lack significant correlation with each other, and instead were found to be statistically independent measures of psychopathology.;Limitations of the study include the use of archival data from an acute inpatient facility and its implications for external validity. Preliminary indications of the constructs measured by the two instruments is discussed, as are suggestions for future studies.
