Psychodynamic variables as predictors of psychotherapy outcome.

Predicting the outcome of psychotherapy is a central concern in psychiatry. Twenty-one medical students seeking psychotherapy were evaluated on a number of psychodynamic and process variables using self-report scales and scales completed by the therapist before, during, and after psychotherapy. There were significant differences between patients and a comparison group on eight variables before therapy. Ten psychodynamic variables (six representing ego defense mechanisms) and four process variables were found to be highly correlated with outcome measures; the process variables were the best predictors of outcome. The data support the use of psychodynamic and process variables as predictors of outcome in psychoanalytically oriented psychotherapy.
