Psychological treatment of depression and anxiety in patients with co-morbid personality disorder: A scoping study of trial evidence

Predicting depression outcomes throughout inpatient treatment using the general and specific personality disorder factors

BACKGROUND

Clinical intuition suggests that personality disorders hinder the treatment of depression, but research findings are mixed. One reason for this might be the way in which current assessment measures conflate general aspects of personality disorders, such as overall severity, with specific aspects, such as stylistic tendencies. The goal of this study was to clarify the unique contributions of the general and specific aspects of personality disorders to depression outcomes.

METHODS

Patients admitted to the Menninger Clinic, Houston, between 2012 and 2015 (N = 2352) were followed over a 6-8-week course of multimodal inpatient treatment. Personality disorder symptoms were assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th edition Axis II Personality Screening Questionnaire at admission, and depression severity was assessed using the Patient Health Questionnaire-9 every fortnight. General and specific personality disorder factors estimated with a confirmatory bifactor model were used to predict latent growth curves of depression scores in a structural equation model.

RESULTS

The general factor predicted higher initial depression scores but not different rates of change. By contrast, the specific borderline factor predicted slower rates of decline in depression scores, while the specific antisocial factor predicted a U shaped pattern of change.

CONCLUSIONS

Personality disorder symptoms are best represented by a general factor that reflects overall personality disorder severity, and specific factors that reflect unique personality styles. The general factor predicts overall depression severity while specific factors predict poorer prognosis which may be masked in prior studies that do not separate the two.

Subthreshold personality disorder: how feasible is treatment in primary care?

Individuals with subthreshold borderline personality disorder (BPD) are commonly encountered in primary care settings, yet the psychological treatments they receive are rarely tailored to their needs. In an effort to capture and treat this group of individuals in a targeted and meaningful way, some primary care settings offer Systems Training for Emotional Predictability and Problem Solving – Emotional Intensity (STEPPS-EI). This evaluation sought to assess the feasibility of STEPPS-EI within NHS primary care services. Employing an uncontrolled design, the evaluation examined recruitment, retention, effectiveness and group appraisal. Findings supported three out of four evaluation objectives for feasibility: uptake of the group was high at 74%, the group was well received by the group and significantly effective at reducing symptoms of BPD, depression and anxiety. However, retention rates were low, with only 43% classed as ‘completers’ of the programme. The results indicate preliminary evidence for STEPPS-EI as a potentially feasible intervention with possible modification to enhance retention and avenues for further study.

Personality and psychiatric disorders in chronic pain male affected by erectile dysfunction: prospective and observational study

The prevalence of personality disorders (PDs) and sexual dysfunction in chronic pain patients is higher than in general population. Our main objective was to analyse the influence of PD in patients with erectile dysfunction and chronic non-cancer pain and their response to andrological treatment. One-hundred one patients were included along 30 months. Pain intensity, quality of life, sexual life quality, anxiety and depression were analysed together with opioid dose. Erectile functioning was measured with the International Index of Erectile Function (IIEF) and PDs with Millon Clinical Multiaxial Inventory (MCMI-III). The mean age was 57 ± 12 years old, with moderate to severe pain, 70% were sexually active and presented moderate to severe ED. PDs were very frequent (31%, cut-off 85 and 84% cut-off 75 scores) mostly anxiety, compulsive, though disorder, somatoform and narcissistic. Self-defeating feature presence was significantly correlated (r = -0.4, 95% CI = -0.605 to -0.145, p = 0.002) with a more severe baseline ED and narcissistic, and a better response to andrological treatment (p = 0.010, d = 1.082). Patients with dysthymia features required significantly higher opioid doses vs. control (238 vs. 102 mg/day, respectively). These findings underline the importance of diagnosing PDs to rigorously treat patients with chronic pain and ED.

GPs' views and experiences of managing patients with personality disorder: a qualitative interview study

OBJECTIVE

The aim of this study was to explore GPs' views and experiences of managing patients with personality disorder (PD), and their views on the role of the Improving Access to Psychological Therapies (IAPT) programme as a support service.

DESIGN

In-depth interviews, analysed thematically.

PARTICIPANTS

Fifteen GPs (7 women and 8 men) of varying age and clinical experience, working in practices that differed in terms of the socio-demographic characteristics of their patient populations.

SETTING

Twelve general practices based in the West of England, UK.

RESULTS

GPs described patients with PD as being challenging to work with and that this work required dedicated time and care. They described experiencing particular difficulty with monitoring their patient's mental health, as well as having little knowledge about the efficacy or availability of treatments for their attenders with PD. They were aware that this patient population often experienced poor mental health and reported a propensity for them to fall into the gap between primary and secondary mental health services, leaving GPs with little choice but to improvise their own management plans, which occasionally involved funding third-sector treatment options. In terms of IAPT services' role in managing these patients, GPs wanted shorter waiting times, better inter-agency communication, more highly trained therapists and more treatment options for patients with PD. They also wanted the service to be able to 'hold' patients with PD in treatment over a longer period than currently offered.

CONCLUSIONS

Findings suggest that, overall, GPs did not consider National Health Service mental health services to offer an effective treatment for patients with PD. While they considered the IAPT programme to be a valuable service for patients with less complex mental health needs, such as depression and anxiety; they felt that the current service provision struggled to meet the needs of patients with more complex mental health needs, as exemplified by people with PD.
