Change in self-discrepancy, anxiety, and depression in individual therapy

This study tested hypotheses of change in the real-ideal (RI) and real-ought (RO) self-discrepancies over the course of therapy, based on Rogers's (1959) theory of personality change in therapy. Before and after therapy with 20 therapists of diverse theoretical orientations at a university counseling center, 99 undergraduate and graduate students completed three instruments that measure both self-discrepancies: the Self-Concept Questionnaire--Personal Constructs, the Self-Concept Questionnaire--Conventional Constructs, and the Abstract Measures. Participants also completed the Beck Depression Inventory-II, State-Trait Anxiety Inventory Trait scale, and the Symptom Checklist-90-R Anxiety and Depression scales. Therapy outcome showed substantial decreases on all measures. Changes in the RI and RO self-discrepancies were associated with changes in anxiety and depression. Change in the RI self-discrepancy was associated with change in the RO self-discrepancy. Decreases in self-discrepancy comprised increases in real self and decreases in ideal self and ought self. Findings were independent of therapist theoretical orientation. The findings support the use of the self-discrepancy instruments in future research on therapy process and outcome. The findings also provide a basis for incorporating the self-discrepancy constructs into theory and research on mechanisms of therapeutic change.
