Emotion regulation strategies in borderline personality disorder: a meta-analysis

ObjectivesMany theoretical models pinpoint emotional dysregulation not only as a symptom of borderline personality disorder (BPD) but also as a component in the development and maintenance of the disorder. In this meta-analysis, results from studies that examined the association between emotion regulation strategies and BPD symptoms were systematically analysed.DesignA quantitative meta-analysis approach was used to systematically assess previous research studies and conduct subgroup and meta-regression analysis to test for theoretical, methodological and demographic moderating variables.ResultsEmotion regulation strategies are significantly and largely associated with BPD symptoms. Negative associations were found between BPD symptoms and acceptance (r = -.558), mindfulness (r = -.581) and reappraisal (r = -.303) and positive associations were found between BPD symptoms and avoidance (r = .528), distraction (r = .336), rumination (r = .551) and suppression (r = .449). As heterogeneity was high, moderating variables (clinical status, type of reporting, comorbidity control, type of population, mean age, percentage of females) were also investigated.ConclusionThe findings highlight the need for active involvement of emotion regulation in explaining BPD psychopathology, as well as promoting interventions focused on individual emotion regulation strategies.What is already known about this topic:(1) The biosocial model of BPD and dialectical behaviour therapy focuses on emotion dysregulation as a core characteristic of BPD.(2) Emotional dysregulation is a core feature of BPD and is strongly involved in the appearance and maintenance of BPD pathology.(3) Emotional regulation difficulties in BPD are also well reflected in the diagnostic criteria according to DSM-5 (APA, 2013).What this topic adds:(1) In the present review, acceptance and mindfulness are considered different emotion regulation strategies.(2) Problem solving is not seen as an emotion regulation strategy because it refers to meta-cognitive processes of dealing with emotions and does not target direct attempts to regulate emotions.(3) Psychological treatments that target the reduction of BPD associated symptoms should continue to focus on emotional dysregulation as a core component of BPD psychopathology.
