Psychotherapy for Sub-Clinical Depression in Children and Adolescents

Cuijpers, P., Pineda, B.S., Ng, M.Y, Weisz, J.R., Muñoz, R.F., Gentili, C., Quero, S., Karyotaki, E. (2021). A meta-analytic review: Psychological treatment of subthreshold depression in children and adolescents. Journal of the American Academy of Child & Adolescent Psychiatry, Online first publication.

Depression occurs in 2.6% of children and adolescents, with as many as 14% of adolescents meeting criteria for a depressive disorder before the age of 18. Depression in youths is related to a number of impairments, negative health outcomes, and to increased risk of depression as an adult. Subthreshold depression represents clinically important depressive symptoms that does not meet diagnostic criteria for major depression or dysthymia. Like major depression, subthreshold depression is related to impairment and increased mortality. Subthreshold depression in adolescents is related to increased risk for developing other disorders including future depressive disorders in adulthood. In this meta analysis, Cuijpers and colleagues present a review of direct comparison randomized controlled trials of psychological interventions for children and adolescents with subthreshold depression. The meta-analysis included 12 trials representing over 1500 children and adolescents. Eight studies tested CBT, and the others tested IPT or supportive therapy. The pooled effect size of the difference between the psychological interventions and control conditions at post treatment was g = 0.38 (95% CI: 0.14 to 0.63), indicating a small to moderate effect of psychological therapies to reduce subthreshold depression in children and adolescents. The authors found some evidence of publication bias (i.e., the likelihood that some studies were conducted but never published) and after adjusting for this bias, the effect size dropped to g = .24 (95% CI: -0.06 to 0.54) which was not statistically significant. There were only two studies of the treatment of children which showed small non-significant effects, g = 0.01 (95% CI: -1.16 to 1.18), however the effects of treatment for adolescents were considerably better, g = .44 (95% CI: 0.16 to 0.71). Longer term follow-up data (6 to 18 months) did not show sustained effects of treatment. Children and adolescents had a 48% lower chance of developing a depressive disorder if they received treatment, although this was not statistically significant.

Practice Implications

The small number of studies limits what one can say about the effects of psychological treatment for subthreshold depression in children and adolescents. The effects were small to moderate at post treatment, but the effects were statistically significant only for adolescents and not for children. Longer term effects of treatments were non-significant, and there was no significant effect on the incidence of depressive disorders at follow up. Despite the disappointing findings, the authors concluded that interventions for subthreshold depression may have positive immediate effects at post treatment for adolescents.
The Emotionally Burdened Psychotherapist

Nissen-Lie, H. A., Orlinsky, D. E., & Rønnestad, M. H. (2021). The emotionally burdened psychotherapist: Personal and situational risk factors. Professional Psychology: Research and Practice. Advance online publication.

To provide good treatment, a psychotherapist must have enough mental and emotional energy to be attuned to the different states of their patients. However, sometimes emotional reserves of therapists can dwindle because of personal or professional burdens. As a result, many therapists report the experience of burnout that inevitably has a negative effect on their patients. Therapists’ personal burdens can be defined as stress in one’s personal life, feeling worry or concern, experiencing conflict within one’s family, or loss of a loved one. These therapist personal burdens could be enduring vulnerabilities or short-lived stressors, but they nevertheless have an impact on the therapist’s effectiveness. Higher stress in a therapist’s personal life is related to more avoidant coping, and lower capacity to stay focused, engaged, and empathic with patients. In this large-scale survey of over 12,000 psychotherapists worldwide (e.g., Norway, US, Canada, UK, Australia, Denmark, China), Nissen-Lie and colleagues looked to identify past and current personal and situational factors that were linked to the experience of personal burden among psychotherapists. The therapists were mostly married or in a committed relationship (72%), half were psychologists, the average length of clinical practice was 12 years (SD = 9.2), and therapists worked almost evenly across the major theoretical orientations (including CBT, psychodynamic, systemic, and behavioral). The most salient predictors of personal burden among psychotherapists were: current health and financial worries, early trauma or abuse, attachment anxiety (i.e., concern about abandonment and difficulty regulating negative emotions), dominant and demanding behavior in relationships, lower work satisfaction, and younger age. Cumulatively, these variables accounted for a substantial amount (30%) of the variance in personal burden.

Practice Implications

Increasingly, research is pointing to negative life events and work experiences that may limit a therapists’ capacity to be engaged and empathic with patients. Focus on therapist well-being should be an important part of clinical training and supervision. Previous research found that receiving personal therapy, obtaining clinical supervision, working shorter hours, and lower caseloads improved empathy and wellbeing among psychotherapists.
Psychotherapies for Depression

Cuijpers, P., Quero, S., Noma, H., Ciharova, M., Miguel, C., Karyotaki, E., Cipriani, A., Cristea, I.A., Furukawa, T.O. (2021). Psychotherapies for depression: A network meta-analysis covering efficacy, acceptability and long-term outcomes of all main treatment types. World Psychiatry, 20, 283-293.

Depressive disorders are common, and they have an important negative impact on quality of life and on mortality. For that reason, the treatment of depression is critical. The most commonly tested psychotherapy is CBT but others like interpersonal psychotherapy (IPT), psychodynamic therapy (PDT), and behavioral activation (BA) have also been tested. In this network meta analysis, Cuijpers and colleagues simultaneously test the effects of different psychotherapies for depression. Network meta-analysis, fundamentally, works by the transitivity assumption: if treatment A = treatment B, and treatment B = treatment C, then treatment A = treatment C even if Treatments A and C were never tested against each other in the same study. This procedure is not without controversy: what if the studies of treatment A vs B are all higher quality (thus resulting in lower effects) than studies of treatments B vs C? Is it fair to equate the studies by comparing treatments A and C when we know study quality impacts effect sizes? Nevertheless, network meta-analyses are used by some to aggregate many studies and to estimate relative outcomes across treatment types. Cuijpers included 331 studies (representing over 34,000 patients) in their network meta-analysis. CBT was tested in over 63% of trials, but other therapies (PDT, IPT, BA) were tested as well. All psychotherapies were more efficacious than care-as-usual and wait list controls with almost no significant differences between therapies for treating depression, except non-directive therapy was less efficacious than other therapies. (Non-directive therapy was often treated as a placebo control condition in studies, and so it may have been delivered in a way that limited its efficacy). CBT, IPT, PDT and BA all were more efficacious than care as usual at 12 months follow up.

Practice Implications

Overall, this network meta-analysis of psychotherapies for depression echoes the findings of many meta-analyses that preceded it. All psychotherapies that were examined, except for non-directive therapy, were equally efficacious for treating depression. When initiating therapy, it may be more important for therapists to be responsive to patient characteristics than to focus on which brand of therapy to deliver. For example, patients with internalizing coping styles may do better with insight oriented therapies, those with high levels of resistance/reactance may require a therapist that is less directive, and patients from marginalized race and ethnic communities may do better with a therapist who is multiculturally competent.

Therapists Are Mostly Responsible for the Therapeutic Alliance

Del Re, A. C., Flückiger, C., Horvath, A. O., & Wampold, B. E. (2021). Examining therapist effects in the alliance–outcome relationship: A multilevel meta-analysis. Journal of Consulting and Clinical Psychology. Advance online publication.

The therapeutic alliance has been consistently found to be a reliable predictor of patient outcomes. The alliance in therapy refers to the patient and therapist collaborative agreement on the tasks of therapy and the goals of therapy, as well as their emotional bond. Previous research suggested that the therapist contribution to the alliance accounted for a significant proportion of patient outcomes. That is, some therapists are better than others at forming a good alliance across a variety of patients, and those therapists who can form a good alliance have patients that achieve better outcomes. If therapists are responsible for most of the effects of a positive therapeutic alliance, then efforts should be directed toward training therapists to improve the alliance. In this meta-analysis of 152 studies, Del Re and colleagues used Patient-Therapist Ratio (PTR) as a proxy to estimate the contribution of the therapist to the alliance. Large PTR refers to many patients per therapist, whereas a low PTR refers to few patients per therapist. A significant effect of low PTR on the alliance – outcome relationship would indicate that most of the effect of the alliance on outcomes was due to the therapist. The overall effect of the alliance on patient outcomes was moderately large (r = .275, 95% CI = .247, .302) and similar to what was found in previous research. In other words, a higher therapeutic alliance between patient and therapist was related to better patient outcomes. PTR was a significant moderator of the alliance – outcome relationship (ß = −0.006, 95% CI = −0.010, −0.002). That is, the therapist had a significant contribution to the alliance – outcome association. There was no evidence of publication bias in the research, and other potential confounds did not significantly reduced the effect of the therapist on the alliance and outcomes.

Practice Implications

The strength of the relationship of the therapeutic alliance to patient outcomes is mostly due to the therapist’s characteristics or actions. That is, therapists are largely responsible for the therapeutic alliance and its impact on patient outcomes. Previous research suggested that more effective therapists have the interpersonal skills to manage interpersonally challenging situations. More effective therapist interpersonal skills include: verbal fluency, instilling hope, persuasiveness, emotional expression, warmth, empathy, and the capacity to repair alliance ruptures. Therapists who are capable of engaging in these facilitative interpersonal behaviors across a range of patients are more likely to achieve outcomes for their patients.
The Impact of Patient Suicide on Psychotherapists

Sandford, D.M., Kirtley, O.J., Thwaites, R., & O’Connor, R.C. (2021). The impact on mental health practitioners of the death of a patient by suicide: A systematic review. Clinical Psychology and Psychotherapy, 28, 261-294.

In the UK, it is estimated that up to 27% of those who commit suicide have been in contact with a mental health professional in the past year. Even though suicide is a rare event, a mental health practitioner is likely to experience at least one instance of a patient suicide during their career. A psychotherapist who experiences a patient suicide could experience symptoms of burnout, PTSD, grief, and a sense of being overwhelmed. Sandford and colleagues conducted a systematic review of the existing research on the impact of a patient’s suicide, experiences of support by the practitioner, and factors that may minimize the negative impacts of patient suicide. They reviewed 54 quantitative and qualitative studies in order to synthesize the research. Professionals included psychiatrists, psychologists, psychotherapists, counsellors, and other mental health professionals. The most common responses of professionals to a patient suicide were guilt, blame, shock, anger, sadness, and grief. Over 20% of practitioners met criteria for PTSD in some studies. Many practitioners across all studies reported some negative impact on their personal life, with 24% identifying severe emotional impact (lower mood, poor sleep). Following a patient suicide, practitioners reported an increased focus on risk assessment, greater caution in their practices, and increased self-doubt about their own judgement. The average practitioner reported an impact that lasted about 4 weeks. A closer therapeutic relationship with the patient, patients who were younger, and the fear of blame and litigation were each associated with a higher level of distress in therapists. However, the impact was not related to therapist gender, age, or experience. Most practitioners felt inadequately prepared for dealing with a patient suicide. But protective factors included support from colleagues, friends and family, and supportive supervision.

Practice Implications

Even if suicide is a rare event in the population, an important minority of patients who commit suicide were in contact with a mental health professional in the preceding year. And so, one might expect to have a patient who commits suicide during one’s career that will have a negative impact on one’s own well-being and professional practice. Increased awareness of the incidence of suicide, informal social supports, and empathic supervision may mitigate the negative impacts. So will tailored training experiences on managing one’s own reactions to patients, as well as a professional work environment that is non-blaming and supportive.
Does Clinical Training Lead to Greater Therapist Interpersonal Skills?

Wolfer, C., Visla, A., Held, J., Hilpert, P., & Fluckiger, C. (2021). Assessing interpersonal skills—A comparison of trainee therapists' and students' interpersonal skills assessed with two established assessments for interpersonal skills. Clinical Psychology and Psychotherapy, 28, 226-232.

Differences between therapists may account for 2% to 8% of the variance in patient mental health outcomes. This seems like a small amount, but the effect is as large as the specific effects caused by interventions of any therapeutic orientation. One of the factors that accounts for differences between therapists is therapist interpersonal skills such as empathy, respectfulness, warmth, openness, and willingness to collaborate. These skills can be learned and likely allow some individuals to be more effective when encountering challenging or complex interpersonal situations. One might think that such skills would be a pre-requisite for entering psychotherapy training, but that may not be the case. A study of training therapists found that more than half of novices were unhelpful to their patients. In this study by Wolfer and colleagues, the authors were interested in seeing if therapists at different stages of training had different levels of these important interpersonal skills. That is, do trainees as a higher level of training acquire more of these skills than those prior to receiving training. This was a small study comparing 19 therapists in clinical training versus 17 students in psychology but with no clinical training. Clinical trainees were in the program for at least 2 years, and received many hours of supervision. All participants watched a video recording of difficult patient statements. Participants’ reactions to the patient video were recorded and then trained raters coded the responses for level of interpersonal skills. Trainee therapists scored significantly higher than students on two scales of interpersonal skills, even after controlling for age. In fact, trainee therapists were over 13 times more likely to demonstrate facilitative interpersonal skills than untrained students. Although being in a clinical training program was associated with greater interpersonal skills, level of experience of clinical trainees (range 2 to 5 years of training) was not related to the level of interpersonal skills.

Practice Implications

This is a relatively small study, so one should consider the findings quite cautiously. Nevertheless, it is one of the few studies to assess interpersonal skills in therapists. It is possible that only those with more interpersonal skills choose to be trained as clinicians – that is, only especially skilled students may go on to receive clinical training. However, the trainees’ substantial amount of clinical training (observing clinicians handle complex situations, receiving supervision to enhance self-reflection) may have facilitated growth in their interpersonal skills. As in previous research, clinical experience alone was not related to therapist interpersonal skill.
