Blog
The Psychotherapy Practice Research Network (PPRNet) blog began in 2013 in response to psychotherapy clinicians, researchers, and educators who expressed interest in receiving regular information about current practice-oriented psychotherapy research. It offers a monthly summary of two or three published psychotherapy research articles. Each summary is authored by Dr. Tasca and highlights practice implications of selected articles. Past blogs are available in the archives. This content is only available in English.
This month...

…I blog about the treatment of depression, the effects of role induction in psychotherapy, and negative experiences in psychotherapy from clients’ perspective.

Indirect Exposure to Trauma Can Lead to Job Burnout and Secondary Traumatic Stress Among Mental Health Providers.
Cieslak, R., Shoji, K., Douglas, A., Melville, E., Luszczynska, A., & Benight, C.C. (2014). A meta-analysis of the relationship between job burnout and secondary traumatic stress among workers with indirect exposure to trauma. Psychological Services, 11, 75-86.
The concept of job burnout was originally developed to document negative consequences of work related exposure to stressful situations experienced by various professionals such as police officers, paramedics, emergency room clinicians, etc. Job burnout can be defined as emotional exhaustion and disengagement. However, recent research on mental health providers has extended the focus beyond job burnout caused by direct exposure, to investigate the consequences of indirect exposure through contact with people who have experienced traumatic events, exposure to graphic trauma content reported by the survivor, or exposure to people’s cruelty to one another. These are sometimes referred to as secondary exposure or indirect exposure to trauma. Professionals indirectly exposed to trauma through their work could experience consequences or symptoms that have been conceptualized as secondary post-traumatic stress, vicarious traumatization, and compassion fatigue, which can collectively be called secondary traumatic stress (STS). STS may include three clusters of symptoms: intrusive re-experiencing of the traumatic material, avoidance of trauma triggers and emotions, and increased physical arousal. Compassion fatigue was defined as a substantial reduction in the mental health providers’ empathic capacity. Cieslak and colleagues (2014) conducted a meta analysis to assess the strength of associations between job burnout and other psychosocial consequences of work-related indirect exposure to trauma in professionals working with trauma survivors. They reviewed 41 studies that included 8,256 workers. The association between secondary traumatic stress (STS) and job burnout in professionals was significant and large. Workers were more likely to experience compassion fatigue and emotional exhaustion compared to PTSD-like symptoms and depersonalization, however, even the association with PTSD-like symptoms and depersonalization was moderate and significant. Both women and men were susceptible to STS, but the effect was larger in women.
Practice Implications
Burnout and other consequences of indirect exposure to trauma are likely to be high among mental health professionals. Burnout will affect professionals’ well being and quality of life, and will diminish their effectiveness with patients through reduced empathy and increased disengagement. Mental health professionals who are exposed to secondary trauma should be aware of the potential for negative personal consequences, and assess their own level of emotional exhaustion, empathic capacity, and engagement. Mental health professionals should seek help if they re-experience the events, engage in avoidance of trauma triggers and emotions, and experience heightened arousal. Taking care of oneself through consultation with trusted colleagues, change in work contexts, social supports, and personal therapy could help to forestall compassion fatigue and burnout. Educational programs to improve self awareness and mindful communication may reduce burnout in mental health professionals.

Does Medicalization of Psychological Problems Reduce Stigma?
Kvaale, E. P., Haslam, N., & Gottdiener, W. H. (2013). The ‘side effects’ of medicalization: A meta-analytic review of how biogenetic explanations affect stigma. Clinical Psychology Review, 33, 782-794.
Psychotherapists may wonder how best to explain a psychological problem to their clients and their family members. Will their explanation help to reduce stigma and increase hope? Laypeople, clinicians, and researchers increasingly understand psychological problems in biomedical terms. Further, some anti-stigma campaigns describe mental health problems, including depression, as biological, medical illnesses. Reducing stigma is important to improve uptake of therapy, reduce an internalized sense of defectiveness, and increase hope and self esteem. Some argue that understanding psychological problems as biologically based will combat stigma by reducing blame and punitive treatment. Kvaale and colleagues asked whether there is a cost to medicalization of psychological problems by unwittingly promoting the stereotype that those with a mental illness have a deep seated, fixed, and defining essence. Proponents of medicalization hope that such an approach will reduce blame for a mental illness, and will result in less desire for social distance from the mentally ill. However, medicalization might also result in: an increased belief that those with psychological problems are dangerous; and greater pessimism and hopelessness about the prognosis (i.e., a belief that the problem can not be improved). A meta-analysis by Kvaale and colleagues looked at experimental studies of student and community based samples in which explanations for a psychological problem was manipulated to include biomedical explanations versus psychological explanations or no explanations. The meta-analysis aimed to examine the causal effects of biogenetic explanations for psychological problems on: blame, perceived dangerousness, social distance, and prognostic pessimism. Regarding blame, the authors reviewed 14 studies that included 2326 participants and found that biogenetic explanations were associated with a decreased tendency to blame individuals with psychological problems. Regarding perceived dangerousness, the authors reviewed 10 studies with 1207 participants, and found that biogenetic explanations were associated with an increase in perceiving those with psychological problems as dangerous. However this result is tentative because publication bias may have resulted in an over estimation of the association (see my May 2013 blog on publication bias [“Are the Effects of Psychotherapy for Depression Overestimated?”]). Regarding social distance, the authors reviewed 16 studies with 2692 participants, but found no relationship between biogenetic explanations and reduced social distance. Regarding prognostic pessimism, the authors reviewed 16 studies with 3469 participants, and found that biogenetic explanations were associated with greater pessimism about the prognosis of a psychological problem.
Practice Implications
The meta analysis by Kvaale and colleagues found that biomedical explanations for psychological problems typically decrease blame, but increase prognostic pessimism and perceptions of dangerousness, although the latter conclusion is somewhat tentative. The findings lead one to be skeptical of the view that stigma will be reduced by promoting an understanding of psychological problems as biogenetic diseases. Kvaale and colleagues suggest that the affected individual, family members and mental health professionals could be more pessimistic about change because of a biomedical explanation, thus impeding the patient’s recovery process. Psychotherapists should share information about the biogenetic factors of psychological problems. However, this must be done with caution. Kvaale and colleagues conclude that explanations that invoke biomedical factors may reduce blame but also may have unintended side-effects. Biogenetic explanations should not be promoted at the expense of psychosocial explanations, which may have more optimistic implications.

Does Focus on Retelling Trauma Increase Drop-out From Treatments For Posttraumatic Stress Disorder (PTSD)
Imel, Z. E., Laska, K., Jakupcak, M., & Simpson, T. L. (2013). Meta-analysis of dropout in treatments for posttraumatic stress disorder. Journal of Consulting and Clinical Psychology, 81, 394–404.
There are now a number of psychotherapies that the Society of Clinical Psychology list as effective psychotherapies available for posttraumatic stress disorder (PTSD). Approaches include prolonged exposure (PE), and cognitive processing therapy (CPT) among others (click here for examples). Therapies for PTSD also vary in how much they focus on retelling the trauma. Some treatments like trauma-focused CBT place a higher level of focus on retelling the trauma event, whereas Present Centred Therapy (PCT), which was originally conceived as a control condition, largely avoids the trauma. Patients may begin a treatment and find some aspect of it distressing resulting in discontinuation. There is ongoing debate regarding the belief that exposure-based treatments, which require the patient to retell traumatic events in detail to his or her therapist, are especially unacceptable or poorly tolerated by patients. Drop out rate is a common metric used to assess tolerability of a treatment. In the April 2013 blog I reported on a meta analysis that found that the average drop out rate in randomized controlled trials of adult psychotherapy was 19.7%. However drop out rates for PTSD in the community can be as high as 56%. Imel and colleagues conducted a meta analysis of drop out rates in randomized controlled trials of treatments for PTSD. They also assessed if drop out rates differed by the amount the therapy focused on retelling the trauma. In the meta analysis, 42 studies were included representing 1,850 patients; 17 of the studies directly compared two or more treatments. The aggregated drop out rates across all studies was 18.28%, which is not different from the rate in randomized trials of adult psychotherapy in general, but is much lower than reported in regular clinical practice. Group treatment was associated with a 12% increase in drop outs compared to individual treatment. In general, an increase in trauma focus was not associated with greater drop out rates. However, when trauma focused treatments were directly compared to PCT (a trauma avoidant intervention) in the same study, trauma-specific treatments were associated with a twofold increase in the odds of dropping out.
Practice Implications
Many have been concerned that exposure-based therapies can lead to symptom exacerbation and result in dropout. The findings of Imel and colleagues’ meta analysis suggest that dropout rates are not significantly different among active treatments. However, PCT may be an exception to this general pattern of no differences among active treatments. Perhaps PCT should be considered a first line treatment for those who do not prefer a trauma focused treatment. In addition, providing treatment for PTSD in groups was associated with greater drop out rates possibly due to shame related to public disclosure of the trauma. The authors suggest mimicking research trial procedures in community practice in order to reduce drop out rates, such as: providing therapist training, support, and supervision; careful patient screening; regular assessment of patient progress; and ongoing contact with assistants that may promote session attendance.

Are the Effects of Psychotherapy for Depression Overestimated?
Niemeyer, H., Musch, J., & Pietrowsky, R. (2013). Publication bias in meta-analyses of the efficacy of psychotherapeutic interventions for depression. Journal of Consulting and Clinical Psychology, 81, 58-74.
Meta-analyses are important ways of summarizing effects of medical and psychological interventions by aggregating effect sizes across a large number of studies. (Don’t stop reading, I promise this won’t get too statistical). The aggregated effect size from a meta analysis is more reliable than the findings of any individual study. That is why practice guidelines almost exclusively rely on meta analyses when making practice recommendations (see for example the Resources tab on this web site). However meta analyses are only as good as the data (i.e., studies) that go into them (hence, the old adage: “garbage in, garbage out”). For example, if the studies included in a meta analysis are a biased representation of all studies, then the meta analysis results will be unreliable leading to misleading practice guidelines. One problem that leads to unreliable meta analyses is called publication bias. Publication bias often refers to the tendency of peer reviewed journals not to publish studies with non-significant results (e.g., a study showing a treatment is no better than a control condition). Publication bias may also refer to active suppression of data by researchers or industry. Suppression of research results may occur because an intervention’s effects were not supported by the data, or the intervention was harmful to some study participants. In medical research, publication bias can have dire public health consequences (see this TED Talk). There is lots of evidence that publication bias has lead to a significant over-estimation of the effects of antidepressant medications (see Turner et al (2008) New England Journal of Medicine). Does publication bias exist in psychotherapy research, and if so does this mean that psychotherapy is not as effective as we think? A recent study by Niemeyer and colleagues (2013) addressed this question with the most up to date research and statistical techniques. They collected 31 data sets each of which included 6 or more studies of psychotherapeutic interventions (including published and unpublished studies) for depression. The majority of interventions tested were cognitive behavioral therapy, but interpersonal psychotherapy, and brief psychodynamic therapy were also included. The authors applied sophisticated statistical techniques to assess if publication bias existed. (Briefly, there are ways of assessing if the distribution of effect sizes across data sets fall in a predictable pattern called a “funnel plot” – specific significant deviations from this pattern indicate positive or negative publication bias). Niemeyer and colleagues found minimal evidence of publication bias in published research of psychotherapy for depression. This minimal bias had almost no impact on the size of the effect of psychotherapy for depression.
Practice Implications
This is a very important result indicating that despite a minor tendency toward a selective publication of positive results, the efficacy of all reviewed psychotherapy interventions for depression remained substantial, even after correcting for the publication bias. Niemeyer and colleagues’ findings demonstrate that publication bias alone cannot explain the considerable efficacy of psychotherapy for depression. Psychotherapeutic interventions can still be considered efficacious and recommended for the treatment of depression.
