Although there is evidence for high comorbidity between borderline personality disorder (BPD) and substance use disorders, particularly alcohol use, more research is needed on the associations between BPD and prescription opioid use because of the increasing national problem of prescription opioid misuse. The purpose of the present study was to examine relationships between BPD features and prescription opioid use, risk for misuse, consequences, and dependence features, and to determine which aspects of BPD account for these associations. ⋯ Additional analyses indicated that most of these effects were accounted for by the self-harm/impulsivity component of BPD. The authors conclude that individuals with more pronounced BPD features may be at risk for use and dependence on prescription opioids, and that this association may be primarily associated with the impulsivity features of BPD.

A systematic review was undertaken to assess the construct validity and responsiveness of four generic health-related quality of life (HRQL) measures in personality disorders (PDs). Ten databases were searched and reference lists scrutinized to identify relevant studies. Relevant data were extracted accordingly. ⋯ Four studies demonstrated that the EQ-5D Index was able to detect changes in patients. The authors conclude that generic HRQL measures appear appropriate for use with people with PDs in terms of psychometric performance. However, qualitative concerns remain as to whether they fully reflect the impact of the condition.

The nosological status of borderline personality disorder as it relates to the bipolar disorder spectrum has been controversial. Studies have supported, in part, the validity of the bipolar spectrum by demonstrating that these patients, compared to patients with nonbipolar depression, are characterized by earlier age of onset of depression, recurrent depressive episodes, comorbid anxiety and substance use disorders and increased suicidality. However, all of these factors have likewise been found to distinguish depressed patients with and without borderline personality disorder. ⋯ The findings indicate that many factors used to validate the bipolar spectrum are not disorder specific. These results raise questions about studies of the validity of the broad bipolar spectrum that do not assess borderline personality disorder. Our results do not support inclusion of borderline personality disorder as part of the bipolar spectrum.

Randomized Controlled Trial Multicenter Study Comparative Study
The effectiveness of cognitive behavior therapy for borderline personality disorder: results from the borderline personality disorder study of cognitive therapy (BOSCOT) trial.
The outcome of a randomized controlled trial of cognitive behavior therapy in addition to treatment as usual (CBT plus TAU) compared with TAU alone (TAU) in one hundred and six participants meeting diagnostic criteria for borderline personality disorder is described. We anticipated that CBT plus TAU would decrease the number of participants with in-patient psychiatric hospitalizations or accident and emergency room contact or suicidal acts over twelve months treatment and twelve months follow-up, compared with TAU. We also anticipated that CBT plus TAU would lead to improvement in a range of secondary outcomes of mental health and social functioning compared to TAU. ⋯ In terms of the number of suicidal acts, there was a significant reduction over the two years in favor of CBT plus TAU over TAU, with a mean difference of -0.91 (95% CI -1.67 to -0.15, p = 0.020). Across both treatment arms there was gradual and sustained improvement in both primary and secondary outcomes, with evidence of benefit for the addition of CBT on the positive symptom distress index at one year, and on state anxiety, dysfunctional beliefs and the quantity of suicidal acts at two year follow-up. CBT can deliver clinically important changes in relatively few clinical sessions in real clinical settings.

Despite the frequent comorbidity of major depression and borderline personality disorder (BPD), limited research has examined what effect this comorbidity has on the severity, course, and presentation of depression. The purpose of this study was to examine whether the severity of major depressive disorder (MDD) in the context of comorbid borderline personality disorder (BPD) differs from MDD when comorbid BPD is not present and to determine whether different measures of depression yield convergent findings. Sixty patients diagnosed with DSM-IV MDD participated in this study. ⋯ Within subgroups, only the retardation factor was correlated with the BDI. Our results suggest that while depressed individuals with and without BPD may be rated as similarly depressed when assessed with objective rating methods, the subjective experience of the depression may be rated as more intense or severe by patients with comorbid BPD. The mechanism underlying this effect remains unknown, and requires further research.
