Abstract
Data from life histories, hospital treatment variables, and scores on pre- and post-treatment MMPIs from 96 hospitalized neuropsychiatric Veterans Administration patients were correlated with criterion scores composed of three post-treatment adjustmental ratings. The patients comprised three different patient groupings: non-psychotic, acute psychotic, and chronic psychotic populations, each of which had a highly different base rate of post-hospital “adjustment.” Each of these patient groups was examined independently and different prognostic indices were found for each patient group. It was suggested that the identification and experimental treatment of small psychologically homogeneous groups is necessary to evaluate treatments.
