Empirical evidence for the effectiveness of long-term psychodynamic psychotherapy (LTPP) in patients with mood disorders is growing. However, it is unclear whether the effectiveness of LTPP is due to distinctive features of psychodynamic/psychoanalytic techniques or to a higher number of sessions. We tested these rival hypotheses in a quasi-experimental study comparing psychoanalytic therapy (i.e., high-dose LTPP) with psychodynamic therapy (i.e., low-dose LTPP) and cognitive-behavioural therapy (CBT) for depression. Analyses were based on a subsample of 77 subjects, with 27 receiving psychoanalytic therapy, 26 receiving psychodynamic therapy and 24 receiving CBT. Depressive symptoms, interpersonal problems and introject affiliation were assessed prior to treatment, after treatment and at the 1-, 2- and 3-year follow-ups. Psychoanalytic techniques were assessed from three audiotaped middle sessions per treatment using the Psychotherapy Process Q-Set. Subjects receiving psychoanalytic therapy reported having fewer interpersonal problems, treated themselves in a more affiliative way directly after treatment and tended to improve in depressive symptoms and interpersonal problems during follow-up as compared with patients receiving psychodynamic therapy and/or CBT. Multilevel mediation analyses suggested that post-treatment differences in interpersonal problems and introject affiliation were mediated by the higher number of sessions, and follow-up differences in depressive symptoms were mediated by the more pronounced application of psychoanalytic techniques. We also found some evidence for indirect treatment effects via psychoanalytic techniques on changes in introject affiliation during follow-up. These results provide support for the prediction that both a high dose and the application of psychoanalytic techniques facilitate therapeutic change in patients with major depression.

The OPD conflict questionnaire Background: To date, no self-report measure is available to assess modes of coping with unconscious conflicts according to Operationalized Psychodynamic Diagnosis (OPD). The OPD conflict questionnaire (OPD-CQ) developed here thus intends to close this gap., Methods: To select the items for the OPD-CQ, expert ratings and psychometric criteria based on a sample of 534 persons were combined., Results: The OPD-CQ comprises 66 items with which active and passive modes of coping with six conflicts as well as defended perception of conflict and emotions can be assessed. Some of the scales had a rather low internal consistency. An investigation of the factor structure of the OPD-CQ scales revealed five factors that could be meaningfully interpreted. The OPD-CQ scales showed expected correlations with other clinically relevant instruments. In addition, we showed the incremental validity of the OPD-CQ scales regarding the prediction of psychological distress and life satisfaction above and beyond structural deficits., Discussion: The results provide important clues toward developing and validating the OPDCQ. The first version presented here should be considered preliminary.
