The Role of Coping Change in Borderline Personality Disorder: A Process-Outcome Analysis on Dialectical-Behaviour Skills Training

Difficulty in emotion regulation is a hallmark feature of patients with borderline personality disorder (BPD). Skills training concepts based on dialectical-behaviour therapy (DBT) are common and effective treatment options for specifically addressing lacking skills in emotion regulation. However, so far it is unclear which aspects of coping change over the course of DBT skills training and if these coping strategies predict symptom change. The present process-outcome analysis, based on a randomized controlled study, aims at investigating these questions, by referring to a general conception of coping and by using an observer-rated approach to assess coping strategies directly in the therapy sessions. In total, n = 31 patients with BPD underwent two individual clinical interview assessments (pre- and post-study intervention; half of the patients underwent DBT skills training, half were in a wait-list control). All individual assessment sessions were transcribed and analysed using the Coping Action Pattern Rating Scale. Outcome was assessed pre- and post-intervention using the Outcome Questionnaire-45.2 and the Borderline Symptom List 23. The results showed increase in overall coping functioning in patients who underwent the DBT skills training, compared with the controls, and specific increases in relatedness coping where the stress is appraised as challenge, along with specific decreases in autonomy coping where the stress is appraised as threat. These changes predicted changes in general distress and borderline symptomatology. The results are interpreted within a general framework aiming at understanding the psychological effects of treatments for BPD, in particular effects related to coping. Effective emotion regulation strategies may therefore be important candidates as potential change mechanisms in treatments for BPD. Copyright © 2016 John Wiley & Sons, Ltd.

KEY PRACTITIONER MESSAGE

It seems important for clinicians to assess the quality of coping strategies as they occur within the session facing a patient with borderline personality disorder. Clinicians may foster the emergence of support-seeking and self-reliance coping strategies in order to increase the effectiveness of therapy. Clinicians may monitor closely the patient's use of ineffective emotion regulation strategies, in particular opposition and submission, with the aim of reducing them early in therapy.

Assertive Anger Mediates Effects of Dialectical Behaviour-informed Skills Training for Borderline Personality Disorder: A Randomized Controlled Trial

Dialectical behaviour therapy (DBT)-informed skills training for borderline personality disorder (BPD) aims at the development of specific emotion regulation skills in patients, particularly with regard to the regulation of problematic anger. While the effects of dialectical behaviour skills training have been shown, their processes of change are rarely examined. Neacsiu, Rizvi and Linehan (2010) found that patient's self-reported use of emotion regulation skills was a mediator of therapeutic change in these treatments; however, they found no effect for problematic anger. From an integrative perspective on anger (Pascual-Leone & Greenberg, 2007; Pascual-Leone & Paivio, 2013), there are several forms of anger, varying in their degree of therapeutic productivity. The present add-on randomized controlled trial included n = 41 patients with BPD (n = 21 DBT-informed skills training versus n = 20 treatment as usual). The first study examined the outcome of the DBT-informed skills training encompassing basic components of training in mindfulness, distress tolerance, interpersonal effectiveness and emotion regulation. Results showed that symptom reduction was significantly greater in the DBT-informed skills training, compared with the treatment as usual. The second study used process assessment, for which all patient completers underwent a 50-min-long psychological interview both early and late in treatment, which was rated using the Classification of Affective Meaning States. DBT-informed skills training produced increased levels of primary 'assertive' anger, as compared with the treatment as usual, whereas no effect was found for 'rejecting' secondary anger. Most importantly, we showed that changes in assertive anger mediated the reported symptom reduction, in particular in patient's social roles. We discuss these results in the context of underlying mechanisms of change in DBT skills group treatments, in particular towards developing more productive forms of anger in this patient population.

KEY PRACTITIONER MESSAGE

A 20-session dialectical behaviour therapy (DBT)-informed skills training is a promising adjunct intervention for patients with borderline personality disorder, in particular for reducing problems related to social role. Increases in assertive anger mediate the effects of DBT-informed skills training, whereas rejecting anger remains unchanged over the course of treatment. Short-term objectives for intervention might involve the specific increase of assertive anger in BPD, by using DBT-informed skills training; long-term objectives for intervention might involve a specific decrease of rejecting anger in BPD.
