Background: Post-traumatic stress disorder (PTSD) with co-occurring severe psychopathology such as borderline personality disorder (BPD) is a frequent sequel of childhood sexual abuse (CSA). CSA-related PTSD has been effectively treated through cognitive-behavioural treatments, but it remains unclear whether success can be achieved in patients with co-occurring BPD. The aim of the present study was to determine the efficacy of a newly developed modular treatment programme (DBT-PTSD) that combines principles of dialectical behaviour therapy (DBT) and trauma-focused interventions. Methods: Female patients (n = 74) with CSA-related PTSD were randomised to either a 12-week residential DBT-PTSD programme or a treatment-as-usual wait list. About half of the participants met the criteria for co-occurring BPD. Individuals with ongoing self-harm were not excluded. The primary outcomes were reduction of PTSD symptoms as assessed by the Clinician-Administered PTSD Scale (CAPS) and by the Posttraumatic Stress Diagnostic Scale (PDS). Hierarchical linear models were used to compare improvements across treatment groups. Assessments were carried out by blinded raters at admission, at end of treatment, and at 6 and 12 weeks post-treatment. Results: Under DBT-PTSD the mean change was significantly greater than in the control group on both the CAPS (33.16 vs. 2.08) and the PDS (0.70 vs. 0.14). Between-group effect sizes were large and highly significant. Neither a diagnosis of BPD nor the severity or the number of BPD symptoms was significantly related to treatment outcome. Safety analyses indicated no increase in dysfunctional behaviours during the trial. Conclusion: DBT-PTSD is an efficacious treatment of CSA-related PTSD, even in the presence of severe co-occurring psychopathology such as BPD.

“…Measures of such factors could be used for improving completion rates in DBT as well as in other psychotherapies which have been demonstrated to improve outcomes in the BPD population, such as transference-focused therapy [38], schema-focused therapy [39], STEPPS [40], mentalisation-based therapy [41], and narrative exposure therapy [42]. Additionally, research on the effectiveness of different levels of care (inpatient, day and outpatient treatments) available to personality disorder patients could shed light on treatment adherence across different modalities [43]. …”

Background: A primary goal of dialectical behaviour therapy (DBT) is to reduce self-harm, but findings from empirical studies are inconclusive. The aim of this study was to assess the effectiveness and cost-effectiveness of DBT in reducing self-harm in patients with personality disorder. Methods: Participants with a personality disorder and at least 5 days of self-harm in the previous year were randomised to receive 12 months of either DBT or treatment as usual (TAU). The primary outcome was the frequency of days with self-harm; secondary outcomes included borderline personality disorder symptoms, general psychiatric symptoms, subjective quality of life, and costs of care. Results: Forty patients each were randomised to DBT and TAU. In an intention-to-treat analysis, there was a statistically significant treatment by time interaction for self-harm (incidence rate ratio 0.91, 95% CI 0.89–0.92, p < 0.001). For every 2 months spent in DBT, the risk of self-harm decreased by 9% relative to TAU. There was no evidence of differences on any secondary outcomes. The economic analysis revealed a total cost of a mean of 5,685 GBP (6,786 EUR) in DBT compared to a mean of 3,754 GBP (4,481 EUR) in TAU, but the difference was not significant (95% CI –603 to 4,599 GBP). Forty-eight per cent of patients completed DBT. They had a greater reduction in self-harm compared to dropouts (incidence rate ratio 0.78, 95% CI 0.76–0.80, p < 0.001). Conclusions: DBT can be effective in reducing self-harm in patients with personality disorder, possibly incurring higher total treatment costs. The effect is stronger in those who complete treatment. Future research should explore how to improve treatment adherence.

“…Treatment developers need to enhance the role of TNC prevention either as part of existing treatments, or as an independent preparatory phase of intervention prior to initiation of other therapies [40]. Future research also needs to address the impact of neuropsychological functions and TNC on symptomatic and functional outcomes longitudinally [41].…”

Higher Executive Control and Visual Memory Performance Predict Treatment Completion in Borderline Personality Disorder

et al. 2011

Background: Non-completion of a prescribed course of treatment occurs in 20–60% of individuals diagnosed with borderline personality disorder (BPD). While symptom severity, personality traits and environmental factors have been implicated as predictors of treatment non-completion (TNC), there have been no studies of neuropsychological predictors in this population. Methods: From a randomized controlled trial, a subsample of 31, unmedicated outpatients diagnosed with BPD with recent self-injurious behavior was assessed on 5 neuropsychological domains. Patients were also assessed for general IQ, demographic and other salient clinical variables. Patients were randomized to one of four treatment conditions, which lasted up to 1 year. Number of weeks in treatment (WIT) up to 1 year was utilized as the index of TNC. Results: Thirty-three percent of the subsample (n = 12) did not complete 1 year of treatment. However, more WIT were predicted by better baseline executive control (Trails B; p < 0.01) and visual memory performance (Benton visual retention; p < 0.001); other neuropsychological domains did not predict WIT. Conclusion: In the treatment of outpatients with BPD, better executive control and visual memory performance predict more WIT. Assessing and addressing these neurocognitive factors in treatment may reduce TNC in this high-risk population.
