Handbook of Psychotherapy and Behavior Change: Starting in March 2013 I will review one chapter a month from the Handbook of Psychotherapy and Behavior Change in addition to reviewing psychotherapy research articles. Book chapters have more restrictive copy right rules than journal articles, so I will not provide author email addresses for these chapters. If you are interested, the Handbook table of content and sections of the book can be read on Google Books.

This month I consider the section in Crits-Christoph and colleagues’ chapter on the process of psychodynamic therapy (PDT). There are a number of PDT models, but they each share some fundamental aspects of treatment or purported mechanisms. One is insight or self understanding, in which patients learn about themselves and their relationships through interventions like interpretations. Self understanding is expected to help patients reduce symptoms by increasing adaptive responses in their important relationships. Transference interpretations may help patients understand their patterns within the therapy relationship, address or change these patterns, and generalize the changes to relationships outside of therapy. Another mechanism might be changes in defensive functioning. Defense mechanisms may be expressions and means of coping with unconscious conflict, needs, and motivations. Change in defensive functioning from less adaptive (e.g. acting out, passive aggression) to more adaptive (e.g., altruism, self observation) may be necessary to achieve improvement in symptoms. Crits-Christoph and colleagues addressed four questions in their review of research on the process of PDT. (1) Are the uses of PDT techniques like transference interpretations related to treatment outcomes?  A number of studies have associated the use of PDT interventions and outcomes, and the average effect size is moderate. In general, transference interpretations were associated with better treatment outcomes. However the findings for transference interpretations are complicated. For example, the use of too many transference interpretations may not be therapeutic and may result in poorer outcomes. A small number of studies looked at the quality or accuracy of transference interpretations and found a moderate relationship between accurate interpretations and good outcomes. Most of these studies did not control for previous improvement in outcomes, so an alternate explanation might be that patients whose symptoms improve facilitate therapists to provide more effective transference interpretations. (2) Is patient self-understanding or insight associated with positive outcomes in PDT? Crits-Christoph and colleagues concluded from their review that changes in self-understanding is an important part of the therapeutic process of PDT. The relationship between insight and outcomes were not evident in CBT or medication interventions, thus suggesting that self-understanding is a specific mechanism of PDT. (3) Is change in defensive functioning related to outcomes in PDT? Only four studies have looked at this question. The studies suggest that improved defensive functioning is related to good outcomes especially for those with more severe problems. However, it remains unclear whether change in defensive functioning causes change in symptoms or the other way around. (4) Is therapist competence in PDT related to treatment outcomes? There is some evidence that competence and adherence in delivering PDT were related to good patient outcomes. Some research also showed that competence and adherence to PDT protocols preceded or caused good outcomes.

Practice Implications

There is good evidence that transference interpretations are related to outcomes, but therapists need to use these judiciously. The research suggests that too many transference interpretations in those with lower levels of functioning, or inaccurate interpretations in general, can reduce outcomes or be related to poorer outcomes. There is also good evidence that patient self understanding of relationship patterns will result in positive outcomes. Self understanding or insight may be a specific mechanism by which PDT works that sets it apart from CBT and the effects of medications. The research also indicates some evidence for the positive effects of changes in defensive functioning, but it is not clear whether change in defenses is a cause of or caused by positive symptom outcomes. Therapist competence and adherence in delivering PDT is also related to good patient outcomes. This highlights the need for training and supervision in evidence based PDT interventions.

(2010). Helpful and hindering events in psychotherapy: A practice research network study. Psychotherapy: Theory, Research, Practice, and Training, 47, 327-344.

There are many reasons why I like this paper, and one reason is that it is a psychotherapy practice research network study (most of the co-authors are independent practice clinicians). This group of clinicians and researchers met on a number of occasions to define the research questions, including: “what do psychotherapists and clients find most and least helpful in a psychotherapy session?”; and “do psychotherapists and clients agree on what was most and least helpful?” The clinicians and researchers also discussed and agreed on the method for collecting and analysing the data. Thirteen independent practice clinicians participated (6 CBT, 4 psychodynamic, and 3 experiental/humanistic). For a period of 18 months, all new clients were invited to participate so that 121 clients with a variety of disorders enrolled in the study. Clients and therapists filled out (on an index card) parts of the Helpful Aspects of Therapy (HAT) measure, which asked them to report, describe, and rate particularly helpful and hindering events from the session they had just completed. For example clients and therapists were asked: “Did anything particularly helpful happen during this session?”; and “Did anything happen during this session which might have been hindering?” When participants answered “Yes” to either of these questions, they were asked to briefly describe the event(s), and then rate them on a scale from 1 to 4 for level of helpfulness or level of hindrance. Both clients and therapists did so at the end of every therapy session. Close to 1500 therapeutic events were recorded by the clients and therapists. The events were then coded and categorized according to type of event by independent raters using an established coding system. Clients rated self-awareness, problem clarification, and problem solution as the most helpful type of events, although self-awareness was significantly the most identified of all helpful events by clients. Therapists rated self-awareness, alliance strengthening, and problem clarification as the most helpful type of events. Therapists identified self-awareness and alliance strengthening significantly more often than any other helpful events. Hindering events were identified much less frequently by clients and therapists. Client identified poor fit (e.g., therapist tried something that didn’t fit the client’s experience) as the most frequent hindering event category. Therapists identified therapist omissions (i.e., failure to provide support or an intervention) as the most frequent hindering event category. Overall, with the exception of self-awareness, therapists and clients did not agree on what were the most helpful or hindering events in therapy.

Practice Implications

Results regarding self awareness indicate that providing clients with opportunities to achieve a clearer sense of their experience (e.g., emotions, behaviors, and perceptions of self) is frequently reported as beneficial by both clients and therapists. The events that therapists most frequently reported as detrimental were those in which they failed to be attuned to their clients’ needs. This may reflect therapists’ concerns with potential alliance ruptures. The overall lack of agreement between therapists and clients on helpful and hindering events raises the question about whether therapists are not aware enough of clients’ experiences, or whether clients are not knowledgeable about what is in fact therapeutic. Perhaps client and therapist ratings of events represent complementary perspectives on what works or does not work in psychotherapy. Regarding participating in research, these independent practice therapists reported that the procedure of writing down helpful and harmful events and reading what their clients wrote after each session had a positive impact on their practice. That is, the process of data collection became immediately relevant to their clinical work.
