The relationships among the Hoffer-Osmond Diagnostic Test, the Minnesota Multiphasic Personality Inventory, and independent clinical diagnoses.
A study was conducted to determine the relationship between two tests in the detection of schizophrenia. One of the tests used was the Minnesota Multiphasic Personality Inventory (MMPI) and the other, a less familiar test, was the Hoffer-Osmond Diagnostic Test (HOD). Also investigated was the difference between the MMPI and the HOD when compared to independently made clinical diagnoses. Of 100 outpatients examined, 75 with valid test results were used. It was hypothesized that the correlation between HOD scores and the Schizophrenia and Paranoia t-scores on the MMPI would be significant. Also, no difference between the two tests and comparable clinical diagnoses was expected. The predicted effects were found. Possible preference for the HOD under certain circumstances was discussed.
