Demonstrating how what a treatment is called by therapists, and how it benefits patients, may be two quite different matters. New methodology for assessing the processes of therapy combine with outcome assessment.

Blatt and his colleagues’ work has shown a wide variety of important clinical features affecting the outcome of treatment.
This study explores the varieties of perceived benefits including changes in self-concept. A careful effort to determine what categories of changes patients actually appreciate after the treatment.

(From the Abstract) The authors conducted a meta-analysis to address the effectiveness of psychodynamic therapy and cognitive behavior therapy in the treatment of personality disorders. METHOD: Studies of psychodynamic therapy and cognitive behavior therapy that were published between 1974 and 2001 were collected. Only studies that 1) used standardized methods to diagnose personality disorders, 2) applied reliable and valid instruments for the assessment of outcome, and 3) reported data that allowed calculation of within-group effect sizes or assessment of personality disorder recovery rates were included. Fourteen studies of psychodynamic therapy and 11 studies of cognitive behavior therapy were included. RESULTS: Psychodynamic therapy yielded a large overall effect size (1.46), with effect sizes of 1.08 found for self-report measures and 1.79 for observer-rated measures. For cognitive behavior therapy, the corresponding values were 1.00, 1.20, and 0.87. For more specific measures of personality disorder pathology, a large overall effect size (1.56) was seen for psychodynamic therapy. Two cognitive behavior therapy studies reported significant effects for more specific measures of personality disorder pathology. For psychodynamic therapy, the effect sizes indicate long-term rather than short-term change in personality disorders. CONCLUSIONS: There is evidence that both psychodynamic therapy and cognitive behavior therapy are effective treatments of personality disorders. Since the number of studies that could be included in this meta-analysis was limited, the conclusions that can be drawn are only preliminary. Further studies are necessary that examine specific forms of psychotherapy for specific types of personality disorders and that use measures of core psychopathology. Both longer treatments and follow-up studies should be included.
Leichsenring, F. & Rabung, S. (2008). Effectiveness of Long-term Psychodynamic Psychotherapy: a Meta-analysis. Journal of the American Medical Association, 300, 1551-1565.
(Modified from the Abstract) Twenty-three studies involving a total of 1053 patients were included (11 RCTs and 12 observational studies). According to comparative analyses of controlled trials, long term psychoanalytic psychotherapy (LTPP) showed significantly higher outcomes in overall effectiveness, target problems, and personality functioning than shorter forms of psychotherapy. With regard to overall effectiveness, a between-group effect size of 1.8 (95% confidence interval [CI], 0.7-3.4) indicated that after treatment with LTPP patients with complex mental disorders on average were better off than 96% of the patients in the comparison groups (P=.002). According to subgroup analyses, LTPP yielded significant, large, and stable within-group effect sizes across various and particularly complex mental disorders (range, 0.78-1.98).

This study of hundreds of patients about seven years after their analyses and psychotherapies is sensitive, in depth, yet methodologically sophisticated. One of the very best.

(2006) Change in attachment patterns and reflective function in a randomized controlled trial of Transference Focused Psychotherapy for borderline personality disorder. Journal of Consulting and Clinical Psychology. 74, 1027-1040.
A superbly organized and executed study showing how the psychodynamic elements make a difference to outcome. Patients with severe and long-standing personality difficulties in psychoanalytic treatment improve significantly in their functioning and emotional health, and they do so by cultivating a greater ability to meaningfully reflect on themselves and others close to them.
A systematic review of studies examining the complex interactions between therapist attachment styles, interpersonal history, and other factors affecting therapists’ subjective self-concept on the one hand, with similar patient personality factors on the other. By attending to one’s own ‘subjective variables’ as a therapist, one can construct interventions better suited to the patient’s needs in treatment.

This randomized study of the results of twice-weekly panic focused therapy compared to a version of cognitive therapy often used to treat panic attacks, each lasting for 24 sessions, is noteworthy for the sophistication of its design.

[This is the complete reference, which should be bolded, like all the others. Here is the annotation which should follow, and which should not be bolded] This volume is a brilliantly written report stemming from a task force of the American Psychological Association Committee on Psychotherapy. Summarizing the entire field, there are also detailed meta analyses across the spectrum of psychotherapy. The first and last chapters do an admirable job summarizing the findings.

International Journal of Psychoanalysis: 81: 921-942.
A complicated study to understand fully, but of the highest quality, showing that the benefits of more intensive work (in comparison with infrequent sessions) begin to show only as the years go on. There are other findings in regard to therapists who attempt to conduct therapy too much like classical analysis, to the detriment of their patients.
This is a classical study, compiling carefully what our patient “consumers” really got out of their treatments. Clear and sensible.

Shea is the lead author in reporting the results of an approximately two-year follow-up of the NIMH 20 million dollar study in the 1980s comparing four different short term treatments of depression, with random assignment to each (the study is more completely described in Wampold, 2000 pp.106-109) The study itself was of only 16 session treatments, and my follow-up less than 25% of the patients overall had maintained their gains.
Shedler, J. (2010). The Efficacy of Psychodynamic Psychotherapy. American Psychologist, 65, 98-109.
(Abstract) Empirical evidence supports the efficacy of psychodynamic therapy. Effect sizes for psychodynamic therapy are as large as those reported for other therapies that have been actively promoted as “empirically supported” and “evidence based.” In addition, patients who receive psychodynamic therapy maintain therapeutic gains and appear to continue to improve after treatment ends. Finally, nonpsychodynamic therapies may be effective in part because the more skilled practitioners utilize techniques that have long been central to psychodynamic theory and practice. The perception that psychodynamic approaches lack empirical support does not accord with available scientific evidence and may reflect selective dissemination of research findings.
Stern, D.N. (1998). The process of therapeutic change involving implicit knowledge: Some implications of developmental observations for adult psychotherapy. Infant Mental Health Journal, 19, 300-308.
Seminal work leading to increasing awareness of the importance of implicit processes in psychotherapy. Despite past bias privileging explicit insights gained by the patient, many important and helpful things occur more implicitly in treatment, in the background of the conversation and often without either therapist or patient realizing.

This monumental, sophisticated and thorough clinical study is fascinating reading. The short version is in the second reference. Patients benefited substantially (see WALDRON, S. Book Review: (1989) Psychoanalytic Quarterly 58: pp. 643-647 for an interesting way of assessing the degree of benefit). Two limitations: there was no comparison group, and there was no recording of the treatments to make possible detailed process assessments. Nevertheless, the study demonstrated strikingly that long term change took place as much with supportive elements as insight.

Werbart, A., Hagertz, M., & Olander, N.B. (2018). Matching patient and therapist anaclitic-introjective personality configurations matters for psychotherapy outcomes. Journal of Contemporary Psychotherapy, 48: 241-251.
This study examined patients and their therapists, according to Blatt’s theory of personality development, and differential personality patterns emphasizing either relatedness or self-definition. The authors found that convergent patterns in patient and therapist were associated with more robust treatment outcomes, and they suggest additional attention and intervention in patients known to differ from therapists in these respects, in order to collaborate effectively in psychotherapy.

These writers demonstrate the inadequacy of the empirically supported approach to benefit, from a variety of convincing perspectives.
