Separation of brain-damaged from psychiatric patients with the combined use of an ability and a personality test: a validation study with a Puerto Rican population.
The purpose of this study was to validate the results obtained by Watson, Gasser, Schaefer, Buranen, and Wold (1981) by utilizing the Smith Symbol-Digit Modalities Test (Form W) and the MMPI (Psychiatric-Organic) scale in combination. Forty recently admitted/readmitted male patients were given both the SDMT and the MMPI (P-O) at a point in their hospitalization in a private inpatient psychiatric hospital in Puerto Rico. The combined use of the Smith and the P-O scale, with the criteria originally developed by Watson et al. (1981), provided a modest level of discrimination by correctly identifying 80% of the brain-damaged sample (organic group) and 55% of the functional sample (psychiatric group) subjects. This combination of tests yielded an overall mean hit rate of 67.5%. These results moderately support the findings obtained by Watson et al. (1981).
