Suggested Contribution & e-training MCT
If you download the MCT material, please consider making a donation ($35/35€ for individuals; $100/100€ for institutions). You may donate online via this link, for more information see here. Your donation will be used to develop and evaluate new (self-help) treatments. Please note that we have developed a certified e-training for the MCT. More information is available at www.uke.de/e-mct.

Metacognitive Training for Borderline Personality Disorder (B-MCT) is derived from Metacognitive Training for Psychosis (MCT). B-MCT was developed as a low-threshold, add-on group intervention for evidence-based treatment. B-MCT targets cognitive biases that play a role in the formation and maintenance of the disorder. Empirical studies confirm its feasibility and efficacy (see, for example, Schilling et al., 2015a; Schilling et al., 2018).

What is Metacognitive Training – Borderline (B-MCT)

Borderline personality disorder (BPD) is characterized by sudden states of intense emotional arousal that are often followed by self-harming behavior or dissociative phenomena. Along with the cardinal symptom of affect dysregulation, BPD may also manifest as an instabile sense of identity and fluctuating self-esteem, problems with social interaction, and dysfunctional behavioral patterns (especially self-harm), as well as deficits in cognitive functioning and biased information-processing patterns. Dysfunctional thinking styles (e.g., an altered attributional style) also seem to play an important role in the development and maintenance of BPD symptoms. In prior studies, we have confirmed that individuals with BPD have cognitive distortions concerning, for example, social cognition and attributional style (for a more detailed presentation of our findings, see the manual and the reference list below).

To improve therapeutic options, we focus on some recently identified BPD-specific dysfunctional thinking styles (e.g., overconfidence in emotion recognition), as well as already well-examined cognitive biases (e.g., dichotomous thinking). B-MCT was developed by our team. Based on our own preliminary studies (e.g., Moritz et al., 2011; Schilling et al., 2012) and numerous studies in the field of basic cognitive research, we adjusted the training units from MCT for psychosis and MCT for depression to address the disorder-specific dysfunctional thought patterns of BPD patients. We also added new examples, with the help of our patients.

B-MCT is a low-threshold add-on intervention for evidence-based standard treatments (especially dialectical behavior therapy, DBT) that specifically targets cognitive biases. The aim of this low-threshold CBT-oriented group intervention is to increase patients’ awareness of their dysfunctional thinking patterns and help them reduce cognitive distortions.

A preliminary study has demonstrated the acceptance and effectiveness of the training. The evaluation clearly showed a large beneficial effect on symptoms as measured by the Borderline Symptom List (BSL-23).

Recently, a controlled randomized study with the modified B-MCT was carried out, and this study confirmed its efficacy in comparison with a relaxation strategy group (Schilling et al., 2018).
