Patient-reported outcomes in borderline personality disorder

Staff Observational Differences Between Depressive Disorders and Personality Disorders

INTRODUCTION

Distinguishing those with a personality disorder from those with major depressive disorder (MDD) can be challenging, but establishing the correct diagnosis can direct appropriate management.

AIM

To identify whether behavioural themes differ between those with personality disorders from those with MDD, and how those differences might relate to a clinical team's perception of diagnosis.

METHOD

An observational study identifying all inpatients presenting with symptoms of depression. At discharge, patients (n = 60) underwent a structured diagnostic interview and were grouped according to diagnosis. Qualitative data was analysed to determine whether behavioural themes differed between those with MDD and those with a personality disorder (with or without MDD).

RESULTS

Ward staff perceptions of diagnosis aligned in all cases of personality disorder, but they also attributed that diagnosis to 54% of patients who had only MDD. Several behavioural themes were evident in those with a personality disorder but not those with MDD. Many behavioural themes were observed in both groups, and it is likely these that drove differences in diagnostic views.

IMPLICATIONS FOR PRACTICE

Certain behavioural themes may be determinants of the perception of diagnosis held by inpatient staff, and when present in acute episodes in MDD, may risk diagnostic misattribution.

Gender differences in treatment effectiveness for borderline personality disorder

Borderline personality disorder (BPD) is a psychological disorder that is diagnosed predominantly in females yet is equally as prevalent in males. Many empirical research studies on the treatment of BPD have been conducted with only female participants. We aimed to investigate the impact of current treatments for BPD on men compared to women. Using data from a larger ongoing longitudinal study, we matched 48 males with 48 females in treatment on age, overall functioning and psychological distress at intake and then accessed their progress in treatment after 12 months. Controlling for the initial scores at baseline, analysis of covariance (ANCOVA) analysis found significant differences in outcome measures at 12-months follow-up. Females had significantly greater improvements in BPD severity and greater improvements in internalizing symptoms such as chronic feelings of emptiness. Females also reported significantly greater satisfaction and ratings of health at follow-up. These findings suggest that current treatment as usual for BPD could be more effective for women compared to men. Results from the study highlight the need for future studies to investigate the experience of males in current BPD treatment and to identify potential areas for modification to better cater to this population.

Development of a screening algorithm for borderline personality disorder using electronic health records

Borderline personality disorder (BoPD or BPD) is highly prevalent and characterized by reactive moods, impulsivity, behavioral dysregulation, and distorted self-image. Yet the BoPD diagnosis is underutilized and patients with BoPD are frequently misdiagnosed resulting in lost opportunities for appropriate treatment. Automated screening of electronic health records (EHRs) is one potential strategy to help identify possible BoPD patients who are otherwise undiagnosed. We present the development and analytical validation of a BoPD screening algorithm based on routinely collected and structured EHRs. This algorithm integrates rule-based selection and machine learning (ML) in a two-step framework by first selecting potential patients based on the presence of comorbidities and characteristics commonly associated with BoPD, and then predicting whether the patients most likely have BoPD. Leveraging a large-scale US-based de-identified EHR database and our clinical expert’s rating of two random samples of patient EHRs, results show that our screening algorithm has a high consistency with our clinical expert’s ratings, with area under the receiver operating characteristic (AUROC) 0.837 [95% confidence interval (CI) 0.778–0.892], positive predictive value 0.717 (95% CI 0.583–0.836), accuracy 0.820 (95% CI 0.768–0.873), sensitivity 0.541 (95% CI 0.417–0.667) and specificity 0.922 (95% CI 0.880–0.960). Our aim is, to provide an additional resource to facilitate clinical decision making and promote the development of digital medicine.

Acute Effect of Physical Exercise on Negative Affect in Borderline Personality Disorder: A Pilot Study

Background

Physical exercise is an evidence-based treatment to reduce symptoms and negative affect in several psychiatric disorders, including depressive, anxiety, and psychotic disorders. However, the effect of physical exercise on negative affect in patients with borderline personality disorder (BPD) has not yet been investigated. In this pilot study, we tested the safety, acceptability, and potential acute effects on negative affect of a single session of aerobic physical exercise in adults with BPD.

Method

After completing a negative mood induction procedure, 28 adults with BPD were randomly assigned to a 20-minute single session of stationary bicycle or a control condition (emotionally neutral video).

Results

No adverse effects attributed to the physical exercise were reported and it was considered acceptable to patients. Following the negative mood induction, both conditions decreased the level of negative affect with a medium effect size but there was no significant difference between them.

Conclusion

The results suggest that a single 20-minute session of physical exercise does not produce a reduction of negative affect in BPD. Future research should consider the duration and intensities of physical exercise with the greatest potential to reduce negative affect both acutely and in a more prolonged manner in this patient group.

The factor structure of the Zanarini Rating Scale for Borderline Personality Disorder: Exploratory Structural Equation Modelling and measurement invariance over time

OBJECTIVES

There is a lack of independent longitudinal evidence on the factor structure and validity of the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD). This study aimed to investigate the dimensionality of ZAN-BPD and its conceptual consistency over time.

METHODS

Adult BPD participants (n = 276) were recruited for a multicentre, two-arm randomised clinical trial with ZAN-BPD measured at baseline and follow up at 12, 24 and 52 weeks. The construct and stability of the ZAN-BPD across 52 weeks was examined through a measurement equivalence/invariance procedure via Exploratory Structural Equation Modelling.

RESULTS

Factor analysis results showed that the ZAN-BPD had a bi-2 factor structure that was stable over 52 weeks with a general factor and two specific factors. Factor loadings for eight of the nine items were greater for the general factor than the two specific factors. Factor 1 contrasts externalising distress with internalising distress. Factor 2 contrasts depression and self-destruction with interpersonal anxiety and conflict.

CONCLUSION

ZAN-BPD is a conceptually and empirically valid measure of total BPD symptom severity in BPD patients over time suitable for use in clinical trials. Two factors related to the expression of distress and self-harm may be utilised as possible predictors of outcome.

Standard set of patient-reported outcomes for personality disorder

PURPOSE

The purpose of the article is to present standard set of outcomes for people with personality disorder (PD), in order to facilitate patient outcome measurement worldwide.

METHODS

The International Consortium for Health Outcomes Measurement (ICHOM) gathered a multidisciplinary international working group, consisting of 16 experts, including clinicians, nurses, psychologists, methodologists and patient representatives, to develop a standard set of outcome measures for people with PD. The Delphi method was used to reach consensus on the scope of the set, outcome domains, outcome measures, case-mix variables and time points for measuring outcomes in service users. For each phase, a project team prepared materials based on systematic literature reviews and consultations with experts.

RESULTS

The working group decided to include PD, as defined by International Classification of Diseases 11th revision (ICD-11). Eleven core outcomes and three optional outcomes across four health domains (mental health, behaviour, functioning and recovery) were defined as those relevant for people with PD. Validated measures for the selected outcomes were selected, some covering more than one outcome. Case-mix variables were aligned to other ICHOM mental health standard sets and consisted of demographic factors and those related to the treatment that people received. The group recommended that most outcomes are measured at baseline and annually.

CONCLUSION

The international minimum standard set of outcomes has the potential to improve clinical decision making through systematic measurement and comparability. This will be key in improving the standard of health care for people with PD across the world.

Drawing the borderline: Predicting treatment outcomes in patients with borderline personality disorder

BACKGROUND

A routinely collected big data set was analyzed to determine the effectiveness of naturalistic inpatient treatment and to identify predictors of treatment outcome and discontinuation.

METHODS

The sample included 878 patients with borderline personality disorder who received non-manualized dialectic behavioral therapy in a psychosomatic clinic. Effect sizes (Hedge's g) were calculated to determine effectiveness. A bootstrap-enhanced regularized regression with 91 potential predictors was used to identify stable predictors of residualized symptom- and functional change and treatment discontinuation. Results were validated in a holdout sample and repeated cross validation.

RESULTS

Effect sizes were small to medium (g = 0.28-0.51). Positive symptom-related outcome was predicted by low affect regulation skills and no previous outpatient psychotherapy. Lower age, absence of work disability, high emotional and physical role limitations and low bodily pain were associated with greater improvement in functional outcome. Higher education and comorbid recurrent depressive disorder were the main predictors of treatment completion. The predictive quality of the models varied, with the best being found for symptom-related outcome (R2 = 18%).

CONCLUSION

While the exploratory process of variable selection replicates previous findings, the validation results suggest that tailoring treatment to the individual patient might not be based solely on sociodemographic, clinical and psychological baseline data.

Use of Ecological Momentary Assessment (EMA) in Non-Suicidal Self-Injury (NSSI): A systematic review

Conceptualization and assessment of non-suicidal self-injury (NSSI) has evolved substantially in recent years. In both cross-sectional and longitudinal studies, NSSI and its related variables have traditionally been assessed retrospectively, leading to less precise studies of the mechanisms involved in the maintenance, cessation, or aggravation of this behavior. Ecological momentary assessment (EMA) enables real-time collection of patient states, which can be very useful in the study of the mechanisms implied in this behavior. This systematic review aims to elucidate the current status of EMA use in NSSI investigation. An exhaustive search in PubMed and PsycINFO was conducted up to September 2017. All papers included were focused on the study of NSSI using EMA. Studies with methodological diversity were included, which were afterwards organized according to main topic of studies. There were no ineligibility criteria based on age or diagnosis. Twenty-three papers were studied, the majority of which are short-term studies focused on the study of affect dynamics and the emotion-regulation function of NSSI. Implications of these results and recommendations for future research are discussed.

User profiles of an electronic mental health tool for ecological momentary assessment: MEmind

Ecological momentary assessment (EMA) is gaining importance in psychiatry. This article assesses the characteristics of patients who used a new electronic EMA tool: the MEmind Wellness Tracker. Over one year, 13811 adult outpatients in our Psychiatry Department were asked to use MEmind. We collected information about socio-demographic data, psychiatric diagnoses, illness severity, stressful life events and suicidal thoughts/behavior. We compared active users (N = 2838) and non-active users (N = 10,973) of MEmind and performed a Random Forest analysis to assess which variables could predict its use. Univariate analyses revealed that MEmind-users were younger (42.2 ± 13.5 years versus 48.5 ± 16.3 years; χ²  = 18.85; P < 0.001) and more frequently diagnosed with anxiety related disorders (57.9% versus 46.7%; χ²  = 105.92; P = 0.000) than non-active users. They were more likely to report thoughts about death and suicide (up to 24% of active users expressed wish for death) and had experienced more stressful life events than non-active users (57% versus 48.5%; χ²  = 64.65; P < 0.001). In the Random Forest analysis, 31 variables showed mean decrease accuracy values higher than zero with a 95% confidence interval (CI), including sex, age, suicidal thoughts, life threatening events and several diagnoses. In the light of these results, strategies to improve EMA and e-Mental Health adherence are discussed.

Recovery and Borderline Personality Disorder: A Description of the Innovative Open Borders Program

Although Recovery-oriented approaches to delivering mental health services are now promoted in health services across the globe, there is an ongoing need to adapt these approaches to meet the unique needs of consumers with a diagnosis of borderline personality disorder. The lived experience of borderline personality disorder includes emotional dysregulation, intense and unstable relationships, self-harming behaviours, fear of abandonment, and a limited capacity to cope with stress. These experiences present a range of challenges for those who deliver Recovery-oriented services and advocate the principles of empowerment and self-determination. This paper describes a novel crisis intervention program, "Open Borders," which has been established to meet the unique needs of people with a borderline personality disorder diagnosis. Open Borders is a Recovery-oriented model that is run at a public, state-wide residential facility for mental health consumers in Western Australia, and offers alternative pathways to achieving mental health Recovery, including self-referral and short-term admission to a residential facility. The aims of the program are to break the cycle of hospital admission, reduce rates of self-harm, and support the complex Recovery journey of consumers with a diagnosis of borderline personality disorder. Open Borders provides an exemplar for other health service organisations seeking to establish Recovery-oriented crisis intervention alternatives.
