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.

Efficacy of Psychotherapies for Borderline Personality Disorder
Cristea, I.A., Gentili, C., Cotet, C.D., Palomba, D., Barbui, C., & Cuijpers, P. (2017). Efficacy of psychotherapies for borderline personality disorder: A systematic review and meta-analysis. JAMA Psychiatry. doi:10.1001/jamapsychiatry.2016.4287.
Borderline personality disorder (BPD) is a debilitating disorder characterized by: severe instability of emotions, relationships, and behaviors. More than 75% of those with BPD have engaged in deliberate self-harm, and suicide rates are between 8% and 10%. BPD is the most common of the personality disorders with a high level of functional impairment. Several psychotherapies have been developed to treat BPD. Most notably, dialectical behavior therapy (DBT), cognitive behavioral therapy (CBT), and psychodynamic treatments like mentalization-based and transference-focused psychotherapy. This meta-analysis by Cristea and colleagues examined the efficacy of psychotherapy for BPD. Studies included in the meta-analysis (33 trials of 2256 clients) were randomized controlled trials in which a psychotherapy was compared to a control condition for adults with BPD. For all borderline-relevant outcomes (combined borderline symptoms, self-harm, parasuicidal and suicidal behaviors) yielded a significant but small effect of the psychotherapies over control conditions at post treatment (g = 0.35; 95%CI: 0.20, 0.50). At follow up, there was again a significant effect of the psychotherapies over control conditions with a moderate effect (g = 0.45; 95% CI: 0.15, 0.75). When the different treatment types were looked at separately, DBT (g = 0.34; 95% CI: 0.15, 0.53) and psychodynamic approaches (g = 0.41; 95% CI: 0.12, 0.69) were more effective than control interventions, while CBT (g = 0.24; 95% CI: −0.01, 0.49) was not. The authors also reported a significant amount of publication bias, suggesting that published results may be positively biased in favor of the psychotherapies.
Practice Implications
The results indicate a small effect of psychotherapies at post-treatment and a moderate effect at follow-up for the treatment of BPD. DBT and psychodynamic treatment were significantly more effective than control conditions, whereas CBT was not. However, all effects were likely inflated by publication bias, indicating a tendency to publish only positive findings. Nevertheless, various independent psychotherapies demonstrated efficacy for symptoms of self harm, suicide, and general psychopathology in BPD.

Direct Psychological Interventions Reduce Suicide and Suicide Attempts
Meerwijk, E.L., Parekh, A., Oquendo, M.A., Allen, I.E., Franck, L.S., & Lee, K.A. (2016). Direct versus indirect psychosocial and behavioural interventions to prevent suicide and suicide attempts: A systematic review and meta-analysis. Lancet Psychiatry.
The World Health Organization reports that more than 800,000 people die of suicide per year around the world. However suicide prevention efforts over the past decade have fallen short of targets. In fact, the prevalence rates of suicide in the US have risen steadily since 2000 to about 1.3% of the population in 2014. Many who kill themselves have a mental disorder like depression, anxiety disorders, substance abuse, psychoses, or personality disorders. Best practices suggest that directly addressing suicidal thoughts and behaviors during treatment, rather than only addressing symptoms like depression and hopelessness, are most effective in reducing suicide. However, there are no meta analyses of randomized controlled trials that specifically assess the relative utility of direct versus indirect psychological interventions. In their meta analysis, Meerwijk and colleagues looked at psychosocial interventions aimed to prevent suicide or to treat mental illness associated with suicide. They included 31 studies representing over 13,000 participants. Interventions included cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), case management, social skills training, and supportive telephone calls. Depending on the target problem, the interventions either directly addressed suicidal behavior or they indirectly addressed suicidal behavior. Mean duration of treatment was over 11 months. Studies that looked at direct or indirect interventions were each compared to control groups that received some form of usual care in the community, or psychiatric management, or general practitioner care. Individuals who received usual care were 1.5 times more likely to die of or attempt suicide compared to those receiving direct or indirect psychological interventions. There was a 35% lower odds of suicide and attempts with direct interventions compared to usual care; and an 18% lower odds of suicide and attempts with indirect interventions compared to usual care. The difference between the effectiveness of direct versus indirect interventions was large (d = .77), suggesting that direct interventions were more effective than indirect interventions at reducing suicide and suicide attempts.
Practice Implications
This is the largest meta analysis of its kind. Most direct interventions to prevent suicide and suicidal behaviors were based on CBT and DBT. Indirectly addressing suicide by focusing on depressive symptoms, anxiety, and hopelessness was somewhat effective compared to usual care. However, direct interventions that included talking about the patient’s suicidal thoughts and behaviors and how best to cope were most effective.
