Prognostic validity of the MMPI.
Attempted to determine the degree to which the MMPI has prognostic validity for psychiatric patients diagnosed as schizophrenic (N = 41). Patient records were analyzed with multiple regression techniques using the MMPI scales as the independent variables and length of hospital stay as the dependent measure. It was found that certain MMPI scales were highly significant and powerful predictors of length of hospital stay, which indicates that the MMPI does indeed have validity as a quantitative predictor of prognosis in clinical situations. Particularly, the two scales with the highest predictive power, Sc and D, were inversely related concerning clinical outcome.
