Background the past decades personality pathology was considered to have a negative influence on the outcome of pharmacotherapy of depressive disorders. Recently, there has been a shift towards a less negative opinion. Still, the evidence in the literature remains inconclusive. This may be explained by methodological differences between published studies. ive sent a meta-analysis of the results of Randomised Controlled Trials with pharmacotherapy in the treatment of depression with comorbid personality disorders. atic literature search for RCTs in adult ambulatory patients with major depressive disorder and comorbid PDs; pooling of data and meta-analysis according to strict methodological criteria. s fference in remission rates between the groups with and without personality disorders in high quality studies was 3%; this difference was neither statistically significant nor clinically relevant. tions the specific and sensitive methods of the search only six studies could be included in the meta-analysis. Due to lack of data, analyses of drop-out rates could not be made. sion nly data from high quality RCTs are included, comorbidity of personality disorder and major depression does not have a negative effect on the treatment outcome of pharmacotherapy for major depression.
