Over the next several months, I will review in this blog results of a number of meta-analyses conducted recently on patient factors and relationship factors in psychotherapy. These factors provide evidence-based guidance to psychotherapists on how best to relate to and adapt to clients so that psychotherapy is more effective. This introductory article by Norcross and Wampold is an overview of the nine meta analyses related to transdiagnostic client factors to which therapists can adapt their interpersonal stances and treatment. The goal is to enhance treatment effectiveness by therapists tailoring therapy to individual client characteristics that are related to outcomes. Decades of research indicate that client transdiagnostic characteristics have more influence on outcomes than the particular treatment method, and likely more influence than the particular client diagnosis. The research indicates that giving the identical treatment to every client without adaptation to client characteristics is not an effective approach to providing psychotherapy. These meta analyses of client factors indicate that therapists should select different interventions and relational stances according to the client and the context. What are these client characteristics and therapist adaptations that are reliably related to outcomes? The client factors most strongly related to outcomes include therapist adaptations to: client culture/race/ethnicity (99 studies, g = .50); client preferences for type of therapy (51 studies, g = .28), client religion/spirituality (97 studies, g = .13 to .43), client stage of change (76 studies, g = .41), client reactance/resistance level (13 studies, g = .78), client coping style (32 studies, g = .53), and client attachment style (32 studies, g = .35). Over the next months, I will be reviewing in more detail these meta analyses of client factors and the practice implications of each so that therapists can use this evidence-base to help them to adapt to particular client characteristics.

Practice Implications

Practitioners will find that fitting the therapy to clients’ culture, stage of change, religion/spirituality, reactance/resistance, coping style, and attachment style will improve treatment outcomes. Doing so will have a greater impact on outcomes than the particular type of therapy provided or adapting treatment to the particular client diagnosis. The results of this large body of evidence suggests that therapists should no longer ask: “what is my theoretical orientation” but rather they should ask: “what relationship, adaptation, and approach will be most effective with this particular client”.

Levy, K.N., Kivity, Y., Johnson, B.N., & Gooch, C.V. (2018). Adult attachment as a predictor and moderator of psychotherapy outcome: A meta‐analysis. Journal of Clinical Psychology. Online first publication, DOI: 10.1002/jclp.22685.

Adult attachment refers to characteristic ways people manage their emotions and relationship styles. Securely attached individuals adaptively and flexibly experience emotions and they are able to give and receive love and support to others. Insecure attachment can be sub-categorized as avoidant or anxious attachment. Those who are anxiously attached tend to up-regulate their feelings so that they may feel easily overwhelmed, and they tend to be preoccupied with relationship loss. Those with avoidant attachment styles tend to down-regulate their emotions so that they have difficulty experiencing or expressing feelings, and they might dismiss the importance of relationships as a means of protecting themselves. John Bowlby, the founder of attachment theory, argued that psychotherapy had the potential to serve as a secure base from which individuals might explore themselves and relationships. He also described the therapist as a temporary attachment figure with which the patient might develop an emotional bond to promote change and for a corrective experience. In this meta-analysis, Levy and colleagues looked at whether attachment dimensions can change in psychotherapy and whether they can predict improvement in patient symptoms pre- to post-therapy. (A note on meta analysis. It is a method of systematically reviewing a research literature, combining the effect sizes in that literature, and summarizing these effects. Because meta analyses usually contain many studies, their results are much more reliable than the results of any single study, and so they provide the most solid basis for making practice recommendations). In this meta analysis, Levy and colleagues included 36 studies, totaling 3,158 clients. Higher client attachment security (or lower attachment insecurity) at the start of therapy was associated with better outcomes by post-treatment (r = 0.17, p < 0.001, 95% CI = [0.13, 0.22], k = 32). Also, greater improvement in attachment security (change in attachment security from pre- to post-treatment) predicted better outcomes (r = 0.16, p < 0.001, 95% CI = [0.07, 0.25], k = 15). When looked at separately, higher levels of either attachment anxiety or attachment avoidance were associated with poorer outcomes, and change in either type of attachment insecurity was associated with better outcomes. These effects appeared to be consistent regardless of the type of therapy (non-interpersonal vs interpersonal therapies).

Practice Implications

Although attachment insecurity is associated with poorer outcomes, change in attachment insecurity is possible with psychotherapy and this change is associated with better symptom outcomes. Therapists should expect longer and more challenging treatment with patients who are anxiously attached. Anxiously attached individuals may appear engaged early in therapy, but they are quick to anger, feel rejected, and become overwhelmed. Such individuals may benefit from help to contain their emotional experiences by repeating the treatment frame and increasing structure. They may also benefit from interpersonally-oriented therapy focused on reducing their preoccupation with relationship loss. Avoidantly attached individuals may appear aloof, but they may be easily overwhelmed by demands for closeness. Therapists may have to carefully balance the amount of interpersonal space or demands in treatment with these clients so that they remain in therapy.

Much of psychotherapy research has focused on searching for effective psychotherapies rather than focusing on effective psychotherapists. Research on psychotherapies generally assumes that therapists are equally effective or relatively less important to patient outcomes than the interventions themselves. Therapists in clinical trials are trained to follow a manual in an attempt to reduce the therapists’ impact on patient outcomes, and to focus the study on the specific ingredients of the therapy itself. However, research indicates that the degree to which a therapist follows a manual has little bearing on patient outcomes, and that therapists do differ in terms of their patients’ outcomes. In one large study, between 33% and 65% of therapists was ineffective or harmful. Okiishi and colleagues asked if it is possible to identify highly effective therapists (“super-shrinks”) and highly ineffective therapists (“pseudo-shrinks”) based on their patients’ outcomes. The therapists were 56 men and women who treated 1779 clients in a university counselling centre. Each therapist saw at least 15 clients, so that there was a good sampling of therapists’ outcomes across a variety of clients. Therapists had a range of experience, training, and theoretical orientations. Clients were adults who had moderate to severe problems with anxiety, depression, or adjustment. Outcomes were measured after every session, and the average number of sessions was 5.16 (SD = 7.20). On average clients improved so that their level of distress significantly declined. Therapist characteristics (sex, experience, training background, theoretical orientation) did not predict patient outcomes. However, client change varied significantly, so that some clients improved at a faster rate than others, some did not change, and some got worse. There were no differences between therapists in their clients’ level of distress, so therapists had equivalent caseloads in terms of client initial distress. However, therapists significantly differed from each other in terms of their clients’ outcomes. For example, the top 3 therapists consistently had clients who got better (super-shrinks), and the bottom 3 therapists consistently had clients who got worse (pseudo-shrinks).

Practice Implications

One would hope that a loved one would get to see a “super-shrink” therapist, since these therapists seem to consistently have clients who do well in therapy. But what about the average or “pseudo-shrink” therapist– what can be done to elevate their skills and their patients’ outcomes? We’ve discussed in this blog several things therapists can do to improve their outcomes, including: using progress monitoring in their practice, receiving training focused on deliberate practice, and seeking out specific continuing education around developing, maintaining, and repairing the therapeutic alliance.

For many authors, one of the purported mechanisms of change in psychotherapy is insight. In fact, the utility of insight for clients with mental health problems was first proposed over 120 years ago by Freud and Breuer. Briefly, insight refers to higher levels of self-understanding that might result in fewer negative automatic reactions to stress and other challenges, more positive emotions, and greater flexibility in cognitive and interpersonal functioning. Although insight is a key factor in some psychodynamic models, it also plays a role in other forms of psychotherapy. Experiential psychotherapy emphasises gaining a new perspective through experiencing, and for CBT insight relates to becoming more aware of automatic thoughts. Jennissen and colleagues defined insight as patients understanding: the relationship between past and present experiences, their typical relationship patterns, and the associations between interpersonal challenges, emotional experiences, and psychological symptoms. In this study, Jennissen and colleagues conducted a systematic review and meta analysis of the insight-outcome relationship, that is the relationship between client self-understanding and symptom reduction. They reviewed studies of adults seeking psychological treatment including individual or group therapy. The predictor variable was an empirical measure of insight assessed during treatment but prior to when final outcomes were evaluated. The outcome was some reliable and empirical measure related to symptom improvement, pre- to post- treatment. The review turned up 22 studies that included over 1100 patients mostly with anxiety or depressive disorders who attended a median of 20 sessions of therapy. The overall effect size of the association between insight and outcome was r = 0.31 (95% CI=0.22–0.40, p < 0.05), which represents a medium effect. Moderator analyses found no effect of type of therapy or diagnosis on this mean effect size, though the power of these analyses was low.

Practice Implications

The magnitude of the association between insight and outcome is similar to the effects of other therapeutic factors such as the therapeutic alliance. When gaining insight, patients may achieve a greater self-understanding, which allows them to reduce distorted perceptions of themselves, and better integrate unpleasant experiences into their conscious life. Symptoms may be improved by self-understanding because of the greater sense of control and master that it provides, and by the new solutions and adaptive ways of living that become available to clients.

Schermuly-Haupt, M. L., Linden, M., & Rush, A. J. (2018). Unwanted events and side effects in cognitive behavior therapy. Cognitive Therapy and Research, 42(3), 219-229.

Unwanted events are negative consequences for clients that may or may not be related to treatment (i.e., events outside of therapy or inside of therapy that may negatively affect clients).  These might include: occupational problems, stigmatization, strains in personal relationships, changes in the social network, patients feeling overwhelmed, undermined self-efficacy, deterioration of symptoms, emergence of new symptoms, suicidality, and others. Side effects refer to negative reactions in clients directly related to appropriately delivered therapy. Research estimates that between 5% and 20% of patients report side effects of psychotherapy. One could argue that side effects may be inevitable even in well-delivered therapy, and therapists who are aware of the potential for side effects may be better equipped to help clients to manage. In this study, Schermuly-Haupt, interviewed 100 psychotherapists who provided CBT in outpatient clinics in Germany about side effects among their clients. All therapists were supervised as part of their work and so the authors assumed the therapy was appropriately delivered. Therapists had on average 5 years of experience and were trained to provide CBT. The interview asked therapists about their most recent treatment case in which the client attended at least 10 sessions. Clients typically had major depression, an anxiety disorder, or a personality disorder, and had attended 28 sessions of therapy on average. During the interview, therapists identified if an unwanted event occurred for a client from a standardized list, and then rated the duration and severity of the effects. They also rated the degree to which the unwanted event was directly related to therapy (i.e., a side effect). Prior to the interview, only 26% of therapists reported their client experienced side effects. However, the interview process found that almost all clients experienced an unwanted event (98%) that may or may have been related to therapy, and 43% experienced at least one side effect that was at least somewhat related to treatment. The most frequent side effects were: “negative wellbeing/distress” (27% of clients), “deterioration of symptoms” (9% of clients) and “strains in family relations” (6% of clients). Of the therapists, 46% rated the side effects as at least moderately severe, and 8.8% of side effects were rated as persistent (lasting more than a month).

Practice Implications

Unwanted events outside of therapy are very common among our clients, but so are side effects from appropriately delivered treatment. Psychotherapy is not always harmless, and it may be best to acknowledge and prepare both clients and therapists for side effects. These may represent ruptures in the alliance that can be managed through alliance-focused therapy, for example. That is, side effects may be caused a mismatch between the goals of a therapist and client, or a disagreement on how to proceed in therapy given what a client needs at the time. Goals and tasks of therapy may need to be renegotiated following the experience of a side effect.

Andrzej Werbart & Mo Wang (2012). Predictors of not starting and dropping out from psychotherapy in Swedish public service settings, Nordic Psychology, 64, 128-146.

There are few empirical studies looking at patients who are offered but who do not take up psychotherapy. This is a particularly important issue in publicly funded psychotherapy programs in which large numbers of patients who need mental health services to not access the service or leave before receiving adequate treatment. Evidence from the Improving Access to Psychotherapy (IAPT) program in the United Kingdom suggests that about half of patients who are offered psychotherapy either do not take it up or drop out prematurely and unilaterally. Knowledge about what determines treatment rejection or dropping out is critical in designing and developing publicly funded psychotherapy so that not only access but also patient outcomes are improved. In this study from the national Swedish psychotherapy program that is publicly funded, Werbart and colleagues looked at data from 13 clinics in which 189 therapists treated almost 1400 patients. Therapists were experienced (median experience = 5 years), and most received advanced psychotherapy training. Patients had a wide array of problems and severity. Of the patients, 13.6% never started therapy even though they were referred and assessed for treatment, and of those who started 17.4% dropped out of treatment. So a total of 31% never received adequate treatment and did not benefit for psychotherapy. Patients who never started therapy tended to be younger, unemployed, and with higher levels of mental illness. Patients who remained in therapy once they started tended to be older, had more problems with trauma or loss, and had more severe illness although they were not a danger to themselves or others. Never starting treatment and dropping out were both associated with clinics that had greater institutional instability. Clinic instability was defined as a clinic with: unclear treatment goals and guidelines, not well adapted to providing psychotherapy, unclear policies around who and how therapy is conducted, less cooperation among professionals, and financial problems.

Practice Implications

Jurisdictions around the world, including in Canada, are looking to offer publicly funded psychotherapy, yet there is little research to guide how to improve uptake and retention of patients within the system. Such systems might focus pre-therapy efforts to retain patients who are younger and with greater mental health problems. In particular, public systems need to pay attention to clinic and institutional stability. How patients experience the clinic environment (as welcoming and integrated), how treating professionals cooperate, the clarity and structure of treatment guidelines and goals, and the financial stability of a clinic all appear to have an impact on whether patients actually access and complete a course of psychotherapy.
