One‐Year Follow‐Up: Schema Therapy for Patients With Borderline Personality Disorder and Comorbid Alcohol Use Disorder

ABSTRACT This article describes the 1‐year follow‐up of a study into the effectiveness of Schema Therapy (ST) for borderline personality disorder (BPD) and comorbid alcohol use disorder (AUD). In the original study, 20 of these patients participated in a multiple baseline case series design study. The results of the original study were promising (a significant decrease of BPD and AUD symptoms). The present study is aimed at examining the longer term benefits of ST for BPD and comorbid AUD. One year after the cessation of the investigational therapy, 17 of the original participants agreed to participate in this follow‐up study. T‐ or Wilcoxon signed rank tests were performed to compare 1‐year follow‐up to start of therapy (baseline). The results suggest that the main therapeutic improvements were generally preserved at 1‐year follow‐up. These findings add to the idea that integrated ST for BPD and comorbid AUD might be effective, also in the long term. A randomized clinical trial is indicated to substantiate this idea.
