Are Treatment Gains Maintained? Long-term Psychological Interventions for Bordeline Personality Disorder

subject

description

IntroductionMany new approaches have been developed to treat borderline personality disorder (BPD) by means of psychotherapy. Though there is a clear research trend towards short-interventions, the evidence from randomised controlled trials (RCT) on longer-term programmes still accumulates. On the one hand, well-established treatments like Dialectical Behavior Therapy (DBT) or Mentalisation-Based Treatment (MBT) are now subject to real-world effectiveness studies; on the other hand, new dynamic approaches have been studied, lasting longer than 6 months.ObjectivesWe are currently updating the cochrane Collaboration review on psychological interventions for BPD. First findings on the effects of longer-term psychotherapies will be presented.MethodsWe conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) according to cochrane collaboration standards. Any randomized comparisons of psychological interventions versus unspecific control interventions, waitlist or specific psychotherapeutic interventions in adult BPD patients were eligible. Primary outcomes were BPD core pathology as depicted by DSM criteria. Secondary outcomes included associated pathology, i.e., depression and anxiety, general psychopathology severity and functioning as well as tolerability and safety. Two researchers selected trials, assessed quality and extracted data independently.ResultsThe current evidence of longer-term psychological interventions in general, and the types of interventions for which RCT evidence is available will be evaluated and critically discussed.Disclosure of interestThe authors declare that they have no competing interest.
