A replication study was undertaken to predict which patients would modify their coping pathology during psychiatric hospitalization and which would not. A total of 65 patients were assessed at the time of admission and again at discharge by multiple observers. The battery of seven predictor scales used measured concepts of premorbid adjustment (expressed both positively and negatively as ego strength and previous history of failure), level of manifest distress at intake, and negative expectations regarding psychotherapy. The multiple correlation found was .57, which is significantly greater than zero at the .005 level of confidence. However, three of the seven scales did not contribute to accuracy of prediction. Among these zero-order correlations was the expectancy score. Overall, the predictors of improvement seemed to generate an index of hope based on previous success and openness to change.In previous articles we have described attempts to predict outcome in a psychiatric open-ward setting. Among the factors used as determinants of improvement were impulse control pathology (Jacobs, Muller, Skinner, Anderson, Pugatch, & Spilken, 1971), overall profile of maladaptive coping (Jacobs, Muller, Skinner, Anderson, & Spilken, 1971), premorbid adjustment, level of manifest distress at the time of admission, and expectations regarding psychotherapy (Jacobs, Muller, Anderson, & Skinner, 1972). Style of coping pathology was later found to be an accurate predictor specific for certain diagnostic classifications (such as depressives), whereas the other factors cited seemed to have more general applicability.This paper is a report of a replication study involving multiple predictors of outcome applicable across diagnostic categories. Following the model of Luborsky, Chandler, Auerbach, Cohen, and Bachrach (1971), we
