Abstract
Objective: Psychotherapy is the first-line treatment for borderline personality disorder (BPD) in evidence-based care. The effects are, on average, medium; however, nonresponse rates point to differential treatment effects. Personalized treatment selection has the potential to improve outcomes, but they depend on the heterogeneity of treatment effects (HTEs), which this article seeks to establish.
Method: Using an extensive database of randomized controlled trials on psychotherapy for BPD, we determined a reliable estimate of this heterogeneity in treatment effects by (a) applying Bayesian variance ratio meta-analysis and (b) estimating the HTE. In total, 45 studies were included in our study. HTE was found for all psychological treatments, although with low degrees of certainty.
Results: Across all psychological treatment and control group types, the estimate for the intercept was 0.10, indicating a 10% higher variance of endpoint values in the intervention groups after controlling for differences in posttreatment means.
Conclusions: The results suggest that, while there might be sufficient heterogeneity in treatment effects, the estimates are uncertain, and future research is needed to gain more accurate boundaries for HTE. Personalizing psychological treatments for BPD by using treatment selection approaches could have positive effects, but the current evidence does not allow for a precise estimate of potential outcome improvement.

期刊介绍：
The Journal of Consulting and Clinical Psychology® (JCCP) publishes original contributions on the following topics: the development, validity, and use of techniques of diagnosis and treatment of disordered behaviorstudies of a variety of populations that have clinical interest, including but not limited to medical patients, ethnic minorities, persons with serious mental illness, and community samplesstudies that have a cross-cultural or demographic focus and are of interest for treating behavior disordersstudies of personality and of its assessment and development where these have a clear bearing on problems of clinical dysfunction and treatmentstudies of gender, ethnicity, or sexual orientation that have a clear bearing on diagnosis, assessment, and treatmentstudies of psychosocial aspects of health behaviors. Studies that focus on populations that fall anywhere within the lifespan are considered. JCCP welcomes submissions on treatment and prevention in all areas of clinical and clinical–health psychology and especially on topics that appeal to a broad clinical–scientist and practitioner audience. JCCP encourages the submission of theory–based interventions, studies that investigate mechanisms of change, and studies of the effectiveness of treatments in real-world settings. JCCP recommends that authors of clinical trials pre-register their studies with an appropriate clinical trial registry (e.g., ClinicalTrials.gov, ClinicalTrialsRegister.eu) though both registered and unregistered trials will continue to be considered at this time.
