Contribution of patient defense mechanisms and therapist interventions to the development of early therapeutic alliance in a brief psychodynamic investigation.

This preliminary study examined how patients' defense mechanisms and psychotherapists' techniques influence early alliance formation. The authors assessed the relationships among defense mechanisms, therapist interventions, and the development of alliance in a sample of 12 patients undergoing Brief Psychodynamic Investigation (4 sessions). Alliance development occurred rapidly and was clearly established by the third session. Neither defensive functioning nor supportive or exploratory interventions alone differentiated early alliance development. However, the degree of adjustment of therapists' interventions to patients' level of defensive functioning discriminated a low alliance from both improving and high alliances. The adjustment of therapeutic interventions to patients' level of defensive functioning is a promising predictor of alliance development and should be examined further, alongside other predictors of outcome.
