Impact of the turning-against-self defense mechanism on the process and outcome of inpatient psychotherapy

The authors examined the relation between specific defense mechanisms and treatment process and outcome in psychodynamic psychotherapy. Three measures, Questionnaire for Conflict Coping Strategies, Questionnaire on the Experience of the Inpatient Therapeutic Process, and Symptom Checklist-90-R, were given to 65 inpatients of a psychosomatic clinic, predominantly with depressive or eating disorders. Turning against self was the most frequently used defense mechanism in the patient group. A high level of turning against self that could be reduced significantly during treatment was associated with good adaptation to treatment setting and positive treatment outcome defined by symptom distress reduction. Assessment of defense mechanisms and their interaction with therapeutic factors in the therapy setting can be useful to better understand the treatment process and the subsequent development of specific interventions to enhance treatment outcome.
