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

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.

A Randomized Controlled Trial Comparing Mentalization-Based Therapy With the Unified Protocol in the Treatment of Psychopathy and Comorbid Borderline + Antisocial Personality Disorders.

BACKGROUND: Those with cooccurring antisocial personality disorder (ASPD) and borderline personality disorder (BPD) are reported to be highly psychopathic and to represent a severe challenge to treatment efforts. In a sample of such individuals, the effects of two treatments, mentalization-based therapy (MBT) and the unified protocol (UP), were investigated on three outcomes: (i) the psychopathy trait domains of meanness, boldness and disinhibition proposed by the triarchic psychopathy model (TPM); (ii) antisocial and borderline symptom severity; and (iii) the severity of their common features including impulsivity, anger expression and self-harm. METHODS: Of 163 individuals with BPD + ASPD screened for eligibility, 55 were randomized to MBT treatment and 53 to UP treatment. Outcomes of treatment were assessed at 6-month intervals to 36 months. RESULTS: Short-term reductions were seen following both treatments in traits of psychopathy, antisocial and borderline personality symptom severity, anger dysregulation, impulsivity and self-harm, but both treatment groups showed almost complete relapse of symptoms at the 36-month follow-up. UP had more durable effects than MBT. CONCLUSIONS: Despite being a considerably shorter treatment, UP was at least as effective as MBT and in some respects superior. Remission of symptoms was not achieved by either treatment in the long term. Psychopathy and borderline/antisocial comorbidity with which it is associated are to some extent remediable through psychotherapy, but only in the short term. CLINICAL IMPLICATIONS: Patients with high levels of impulsivity and disinhibition are likely to relapse following psychotherapy and should be closely monitored after treatment.

Características de las alucinaciones en el trastorno límite de la personalidad. Similitudes y diferencias con la esquizofrenia y el trastorno bipolar.

La psicosis puede ser considerada una dimensión que en su extremo de mayor gravedad puede expresarse con alteraciones en la sensopercepción, principalmente alucinaciones. Su presencia es un hecho que se constata con frecuencia en patologías psiquiátricas severas como la esquizofrenia (EZQ) y el trastorno bipolar (TB) donde pueden ser marcadores de gravedad. No obstante, las alteraciones sensoperceptivas no son patognomónicas de estos trastornos ni señalan ninguna de estas enfermedades como un hecho aislado. Dicha sintomatología puede ser descripta en diversas situaciones dentro y fuera de la psicopatología. En este sentido, proponer una línea directa entre las alucinaciones con enfermedades tales como la EZQ o el TB desestima su ocurrencia en otras patologías, como es el caso del Trastorno límite de la personalidad (TLP). Es factible que constatemos la expresión de alucinaciones en pacientes con este trastorno y su presencia puede tener connotaciones etiológicas, clínicas y terapéuticas que deben ser revisadas para tener en cuenta en nuestra práctica clínica.

Atypical semantic cognition in schizotypal personality disorder and borderline personality disorder.

Increased schizotypal traits have previously been associated with atypical semantic cognition in community samples. However, no study has yet examined whether adults diagnosed with schizotypal personality disorder (SPD) display atypical semantic fluency and memory. We hypothesized that 24 adults diagnosed with SPD would name more idiosyncratic words on the semantic fluency task and show decreased semantic recall for animal and fruit category words compared with 29 participants with borderline personality disorder (BPD) and a community sample of 96 age-matched controls. We examined whether atypical semantic cognition was specifically associated with disorganized and eccentric speech and thinking, or more broadly with pathological personality traits and personality functioning. Our main hypothesis was confirmed, as the SPD participants named more idiosyncratic words and recalled fewer semantically related words compared with controls. Surprisingly, participants with BPD likewise named more atypical words compared with controls. More idiosyncratic semantic fluency was associated with more eccentric speech and thinking. Increased idiosyncratic semantic fluency and reduced semantic recall were both coupled to increased detachment and lowered personality functioning, while reduced semantic recall further was related to increased interpersonal problems. Our findings suggest that persons with SPD, and to a lesser degree BPD, show atypical semantic cognition, which is associated with eccentric speech and thinking, and more broadly with impaired personality function, social withdrawal, and emotional flatness. The idiosyncratic semantic cognition may worsen difficulties with social reciprocity seen in SPD and BPD.

A Cluster Analysis of Neuropsychological Impairment in Borderline Personality Disorder: Identifying a Neurocognitive Subtype Linked to Attention Deficit Hyperactivity Disorder.

INTRODUCTION: Cognitive impairment associated with borderline personality disorder (BPD) has been consistently demonstrated. However, a specific neuropsychological profile has not yet been established for this disorder, maybe due to the heterogeneity of BPD. The aim of this work is the search for distinct neuropsychological subtypes among patients with BPD and for the association of neuropsychological subgroups with specific clinical characteristics. METHODOLOGY: One hundred fifteen patients with BPD diagnosis received an extensive neuropsychological evaluation assessing attentional, memory and executive functions indexes. For subtyping strategies, a cluster analysis of neuropsychological BPD distribution was performed. Central clinical dimensions of BPD were measured and analysed in relation with the obtained neuropsychological clusters. RESULTS: Two clusters were found: Cluster 1 showed a significantly lower score on the working memory index, and Cluster 2 had significantly worse overall executive performance, response inhibition and planning abilities. Patients in the neurocognitive Cluster 2 showed significantly higher clinical deficits of attention as measured with subscales of the CAARS attention deficit hyperactivity disorder (ADHD) index (F = 2.549, p < 0.005, d = 11.49). CONCLUSIONS: Two neuropsychological clusters of patients were found in the BPD sample: Cluster 1 patients showed greater impairment in working memory, while Cluster 2 patients had greater deficits of executive functioning, particularly for response inhibition and planning. In addition, BPD patients with greater executive deficits presented greater levels of ADHD clinical features. These findings might also facilitate earlier diagnosis of severe BPD patient profiles and to establish more personalized treatment based on neurocognitive stimulation.

Self-Hatred: The Unaddressed Symptom of Borderline Personality Disorder.

Individuals with borderline personality disorder (BPD) often report chronic, severe self-hatred. It is frequently experienced as immutable, seen as a barrier to recovery, and is associated with risk for self-injury and suicide attempts. Yet self-hatred remains a poorly understood, underdiagnosed, and undertreated presentation of BPD. In this concept article and review, we describe the nature of self-hatred in BPD and related disorders, propose a theory as to the development of self-hatred in BPD, review the assessments of and interventions for self-hatred, and consider next steps in the research, assessment, and treatment of self-hatred in BPD. Through increased awareness, understanding, and measures of self-hatred in BPD, new treatment paradigms can be developed to ensure more comprehensive recovery.

Brexpiprazole Attenuates Aggression, Suicidality and Substance Use in Borderline Personality Disorder: A Case Series.

Background: Borderline personality disorder (BPD) is a heterogeneous and highly comorbid disorder. Suicidality, aggression and substance abuse are common presentations of BPD. Our case series is the first to highlight the role of brexpiprazole in improving these symptoms in patients with BPD. Case presentation: We describe three cases demonstrating the role of brexpiprazole in improving BPD's prominent features and comorbidities. All cases improved when brexpiprazole was added to their treatment regime. Case 1: A 26-year-old woman who was diagnosed with BPD and cyclothymia, presented to the psychiatric emergency unit with impulsive suicidal behaviour. Case 2: A 43-year-old woman suffering from BPD sought help due to her violent behaviour and emotional dysregulation. Case 3: A 22-year-old woman with underlying attention deficit and hyperactivity disorder, polysubstance use disorder and BPD presented with dysregulated emotions. Conclusions: Our case series provides anecdotal evidence of the potential role of brexpiprazole in attenuating suicidality, aggression and substance abuse in patients with BPD. We postulate that brexpiprazole's high affinity for the 5HT1A/5HT2A receptors, coupled with its low intrinsic effect on the D2/D3 receptor system, is fundamental in its actions to stabilise the aberrant dopaminergic and serotonergic signalling in BPD. Future research should focus on well-designed clinical trials investigating the efficacy of brexpiprazole in patients with BPD.

A phenomenological comparison of auditory hallucinations between borderline personality disorder and schizophrenia: A systematic review.

OBJECTIVE: Borderline personality disorder (BPD) with auditory hallucinations (AHs) may inadvertently be misdiagnosed with a primary psychotic disorder, such as schizophrenia (SZ). This misidentification can lead to challenges in providing effective psychological treatment. This review therefore aims to identify the phenomenological characteristics of AHs in BPD in comparison to SZ, as well as psychological interventions that explicitly target AHs in BPD. METHODS: A systematic review was conducted to summarise the existing evidence base regarding the phenomenological similarities and differences of AHs in BPD and SZ, along with the identification of psychological interventions for AHs in BPD. RESULTS: Eighteen studies were eligible for inclusion. Compared to the SZ group, BPD clients were characterised by more persistent and repetitive AHs, significantly more voice-related distress and appraisals of omnipotence, and an earlier age of onset of AHs. The BPD group also reported more severe depression and anxiety, a higher incidence of childhood trauma, and more negative self-schema. Cognitive Behaviour Therapy Coping Strategy Enhancement (CBT-CSE) might be a promising intervention to reduce AH-related distress in BPD, although further studies are required to determine its effectiveness. CONCLUSION: In order to prevent misdiagnosis of AHs in BPD, the DSM-5 may need to acknowledge the broader and more frequent occurrence of psychosis symptoms in BPD clients. Such clarification may enhance diagnostic practices and facilitate more timely access to treatment. There is also a need to develop and trial psychological interventions that explicitly target AHs in BPD.

Psychopathology and psychosocial functioning among young people with first-episode psychosis and/or first-presentation borderline personality disorder.

BACKGROUND: One in five young people with first-episode psychosis (FEP) also presents with borderline personality disorder (BPD) features. Among people diagnosed with BPD, auditory verbal hallucinations occur in 29-50 % and delusions in 10-100 %. Co-occurrence of psychotic symptoms and BPD is associated with greater clinical severity and greater difficulty accessing evidence based FEP care. This study aimed to investigate psychotic symptoms and psychosocial functioning among young people presenting to an early intervention mental health service. METHOD: According to the presence or absence of either FEP or BPD, 141 participants, aged 15-25 years, were assigned to one of four groups: FEP, BPD, combined FEP + BPD, or clinical comparison (CC) participants with neither FEP nor BPD. Participants completed semi-structured diagnostic interviews and interviewer and self-report measures of psychopathology and psychosocial functioning. RESULTS: The FEP + BPD group had significantly more severe psychopathology and poorer psychosocial functioning than the FEP group on every measure, apart from intensity of hallucinations. Comparing the FEP or BPD groups, the BPD group had greater psychopathology, apart from intensity of psychotic symptoms, which was significantly greater in the FEP group. These two groups did not significantly differ in their overall psychosocial functioning. Compared with CC young people, both the FEP + BPD and BPD groups differed significantly on every measure, with medium to large effect sizes. CONCLUSIONS: Young people with co-occurring FEP and BPD experience more severe difficulties than young people with either diagnosis alone. This combination of psychosis and severe personality pathology has been longitudinally associated with poorer outcomes among adults and requires specific clinical attention.

Recurrent Mental Health Presentations to Public Hospital Services: A Focus on Borderline Personality Disorder.

Objective: To investigate associations between patients with borderline personality disorder (BPD)-related symptoms and their hospital presentations as well as the effect of inpatient length of stay (LOS) on time to hospital re-presentation.Methods: A retrospective cohort design was used to investigate mental health emergency department (ED) visits and inpatient admissions. The cohort comprised 13,320 men and 12,290 women with a follow-up period between January 1, 2014, and December 31, 2019.Results: Across all presentations in the study period, approximately 4% of mental health patients were discharged from ED or inpatient admission with primary diagnosis of BPD. Both male and female patients with BPD were at higher risk of hospital re-presentation when compared to patients with any other type of mental disorder (P < .01). Patients with BPD who had LOS > 14 days in their first inpatient admission were, on average, more likely to experience a repeat ED or inpatient presentation 58 days sooner than patients who had LOS < 2 days (P = .036).Conclusions: Findings suggest the need for (a) more accurate recording of BPD and related presentations, (b) more in-depth investigations of BPD care pathways, and (c) identifications of subpopulations who may benefit from a specific inpatient length of stay.Prim Care Companion CNS Disord 2024;26(1):23m03559.

[Alexithymia and self-harm in people with borderline personality disorder]. / Aleksitimiya i samopovrezhdayushchee povedenie u lits s pogranichnym rasstroistvom lichnosti.

OBJECTIVE: To estimate the prevalence of alexithymia and self-harm in patients with borderline personality disorder (BPD). To assess the role of alexithymia in the emergence of self-harm in patients with BPD. MATERIAL AND METHODS: We studied 104 patients (85 women, 19 men aged 21 to 25 years (64.4%)), including 54 patients with and 50 patients without BPD. Most of them had incomplete higher education (55%). We used the Russian version of the 20-item Toronto Alexithymia Scale (TAS-20) to reveal alexithymia and SCID-II to diagnose BPD. The presence of self-harm behavior was confirmed by the subjects' anamnesis data. RESULTS: The prevalence of alexithymia in patients with BPD was 83.3%, in the control group it was 52% (p=0.001). The prevalence of self-aggression was 70.3% (n=38) in patients with BPD, and 12% (n=6) in people without BPD. Self-harm among persons with alexithymia was noted in 62.5% (n=45). During the analysis, a connection between auto-aggression and alexithymia was found at the level of a statistical trend (p=0.051). CONCLUSION: Alexithymia and self-harm are more common in patients with BPD than in healthy people. This type of emotional dysregulation mediates self-harm in patients with BPD.

Dialectical Behavior and Social Rhythm Therapy for Comorbid Bipolar Disorder and Borderline Personality Disorder.

Bipolar disorder and borderline personality disorder commonly co-occur. Each disorder is associated with substantial morbidity and mortality, which are worsened by co-occurrence of the disorders. Emotional dysregulation, suicidality, and disrupted circadian rhythm are key aspects of psychopathology associated with both conditions. A novel psychotherapy combining elements of two evidence-based treatments (i.e., dialectical behavior therapy [DBT] for borderline personality disorder and social rhythm therapy [SRT] for bipolar disorder) is described. Unlike either treatment alone, the new therapy, called dialectical behavior and social rhythm therapy (DBSRT), targets all three disease-relevant processes and therefore may represent a promising new approach to treatment for individuals with these two conditions. DBSRT may also have utility for individuals with overlapping characteristics of bipolar disorder and borderline personality disorder or for those whose illness manifestation includes a mix of bipolar and borderline personality disorder traits. Strategies associated with DBSRT are described, and a brief case vignette illustrates its application.

Borderline personality features are associated with worse perceptions of (but not compliance with) chronic pain treatment.

Treating chronic illness requires ongoing patient-provider cooperation, but individual differences in patients' negative perceptions of care can undermine this cooperation. Research suggests people high on borderline personality disorder (BPD) features may react negatively to and comply less with mental health and medical treatment. This might be particularly problematic in chronic pain treatment, where BPD features are over-represented and the dysregulation typifying BPD likely undermines consistent care. In a sample of 147 chronic pain patients, we investigated whether higher levels of BPD features - both in general and by specific facets - predicted worse perceptions of treatment and lower patient-reported compliance with treatment recommendations. Participants higher (vs. lower) on borderline features viewed treatment more negatively but did not report complying less with recommendations. We found evidence that this may reflect the unstable relationships facet of BPD. Our results indicate that, consistent with other treatment settings, BPD features may undermine care for chronic pain. Furthermore, our results highlight the importance of collaborative provider-patient relationships and patient agreement with the treatment of chronic pain, particularly among individuals higher on BPD features.

Intranasal oxytocin as an adjunct treatment among patients with severe major depression with and without comorbid borderline personality disorder.

INTRODUCTION: Results of studies concerning a possible beneficial effect of Intranasal-Oxytocin (IN-OT) as an add-on treatment for patients with major depression (MDD) have been inconsistent. One possible explanation to account for the difference in the effect of IN-OT is comorbid borderline personality disorder (BPD). This randomized controlled study was aimed to explore the differential effect of IN-OT administration among depressive patients with or without comorbid borderline personality disorder. METHODS: A secondary analysis was conducted on a specific subset of patients who participated in an RCT evaluating the impact of IN-OT as add-on treatment for patients with severe mental illness. Patients treated in inpatient settings (N = 58) were randomized and double-blindly allocated to receive twice daily IN-OT (32 IU) or placebo for a period of four weeks. The effect of IN-OT on therapy process and outcome was examined among patients with (n = 35) and without (n = 23) comorbid BPD. RESULTS: An interaction effect between diagnosis and group was observed on the Outcome Questionnaire-45 (B = 8.93, p = .007). Further analysis revealed that patients without BPD demonstrated significantly greater improvements following OT administration (B = -8.32, p = .001), whereas patients with BPD did not show significant improvement (B = 0.61, p = .76). The interactive pattern was also observed in the Hopkins Symptom Checklist (B = 0.25, p = .02), where patients without BPD demonstrated significantly larger improvements following OT administration (B = -0.29, p = .0009) as compared to placebo, while patients with BPD demonstrated no significant improvement (B = -0.04, p = .55). We did not find a harmful effect of IN-OT administration among patients with MDD and comorbid BPD. CONCLUSIONS: Patients with MDD and comorbid BPD benefit less from IN-OT administration as compared to depressed patients without BPD. Future studies should aim to identify patients who are more likely to benefit from IN-OT administration.

Association of white matter microstructural alteration with non-suicidal self-injury behavior and visual working memory in adolescents with borderline personality disorder.

BACKGROUND: Non-suicidal self-injurious behavior (NSSI) is the core characteristic of adolescent borderline personality disorder (BPD) and visual working memory is involved in the pathological processes of BPD. This study aimed to investigate alterations in white matter microstructure and their association with NSSI and visual working memory in adolescents with BPD. METHODS: 53 adolescents diagnosed with BPD and 39 healthy controls (HCs) were enrolled. White matter microstructure was assessed with the fractional anisotropy (FA) and mean diffusivity (MD) from diffusion tensor imaging (DTI). Correlation analysis was performed to assess the association between FA/MD and core features of BPD. A mediation analysis was performed to test whether the effects of white matter alterations on NSSI could be mediated by visual working memory. RESULTS: Adolescents with BPD showed a reduced FA and an increased MD in the cortical-limbic and cortical-thalamus circuit when compared to the HCs (p < 0.05). Increased MD was positively correlated with NSSI, impulse control and identity disturbance (p < 0.05), and was negatively correlated with the score of visual reproduction. Reserved visual working memory masked the effects of white matter microstructural alterations on NSSI behavior. CONCLUSIONS: White matter microstructural deficits in the cortical-limbic and cortical-thalamus circuits may be associated with NSSI and visual working memory in adolescents with BPD. Reserved visual working memory may protect against NSSI.

Effects of borderline personality disorder symptoms on dialectical behavior therapy outcomes for eating disorders.

Existing literature on the effects of borderline personality disorder (BPD) and eating disorder (ED) comorbidity in terms of clinical presentation and treatment outcome has been limited and inconclusive. The present study examined whether clients with EDs and varying levels of BPD symptoms presented with more severe ED symptoms at admission, and whether they responded to dialectical behavior therapy (DBT)-based treatment. Participants (N = 176) were adults in a DBT-based partial hospitalization program for EDs at an academic medical center. Participants completed self-report measures at admission, 1-month postadmission, discharge, and 6-month follow-up. Results suggested that patients with elevated BPD symptoms at admission had greater ED symptoms during treatment, evidenced by small to moderate effect sizes. However, patients with high BPD symptoms demonstrated steeper declines in binge eating, fasting, and parasuicidal behavior early during treatment compared to patients with low BPD symptoms. Individuals with high BPD symptoms at admission (i.e., probable BPD diagnosis) were as likely to meet remission criteria and relapse as individuals with low BPD symptoms, though this null finding may be influenced by small cell sizes. Our findings also suggest that DBT skills use does not predict changes in symptoms. In sum, our findings suggest that while clients with higher BPD symptoms may improve during DBT-based partial hospitalization, their ED symptoms may remain more severe. Future studies are needed to determine whether adjunctive treatments improve outcomes for clients with EDs and comorbid BPD symptoms in DBT programs and whether skills use quality is a better predictor of ED symptom changes.

Social cognition deficits in borderline personality disorder: Clinical relevance.

Interpersonal difficulties in borderline personality disorder (BDP) have been suggested to be related to impairments in Social Cognition (SC), mainly due to deficits in Theory of Mind (ToM). However, literature is scarce and ambiguous. This work aims to study the SC impairments in BPD patients, by the specific assessment of ToM deficits, and to investigate the relationship between these SC impairments and clinical variables. 82 BPD patients with BPD and 47 control subjects were assessed with the Movie for the Assessment of Social Cognition (MASC). Clinical variables of severity, chronicity, functionality and anxious-depressive symptomatology were recorded. BPD patients had fewer correct mentalization responses and more overmentalization, undermentalization, and absence of mentalization errors than controls. Chronicity was negatively correlated with overmentalization and positively correlated with undermentalization and absence of mentalization errors. Functionality was indirectly correlated with absence of mentalization. These results confirm previous reports of alterations in SC in BPD patients. Furthermore, this study shows that SC impairments in patients with BPD are dependent on characteristics such as chronicity or degree of functionality. The different ToM profiles in patients with BPD indicate the necessity of developing variants of mentalization therapy depending on the deficits of each patient.

The 8-Year Course of Acute Physical Pain Reported by Patients With Borderline Personality Disorder and Comparison Subjects With Other Personality Disorders.

The present study examines the 8-year course of physical pain and its interference with functioning in patients with borderline personality disorder (BPD) and a comparison group of patients with other personality disorders (other-PD). Participants completed the Brief Pain Inventory (BPI) at five assessments, each separated by 2 years. Results showed that across all 13 domains assessed, participants with BPD reported significantly higher levels of acute physical pain and its functional interference than other-PD comparison subjects. The severity of physical pain and its interference with multiple domains of functioning were relatively stable over 8 years of assessment for both study groups. Within the BPD group, pain was significantly associated with older age, comorbid major depressive disorder (MDD), and history of a physically violent partner. Taken together, these results suggest that physical pain is a serious health issue for individuals with BPD that interferes with functioning across a wide spectrum of areas.

Neurocognitive profile associated with borderline personality disorder: building specific indices of executive function.

The objective of this work is the creation of specific indices of the different executive functions (EF).

The biosocial correlates and predictors of emotion dysregulation in autistic adults compared to borderline personality disorder and nonclinical controls.

BACKGROUND: Emotion dysregulation (ED) is a core symptom of borderline personality disorder (BPD), whose aetiology has been attributed to biosocial factors. In autism spectrum condition (ASC), although ED is prevalent and is associated with decreased well-being (e.g. self-harm, suicidality), it has been understudied, especially in adults. It is therefore crucial to further understand ED in autistic adults to improve its treatment. Our study investigates ED, its behavioural correlates (e.g. self-harm, suicidality) and biosocial predictors in autistic adults relative to BPD and nonclinical controls (NC). METHODS: A total of 724 participants (ASC = 154; BPD = 111; NC = 459) completed 11 self-reported questionnaires assessing ED, ASC and BPD traits, co-occurring disorders, alexithymia, emotional vulnerability and invalidating experiences (e.g. bullying, autistic camouflaging). The occurrence of ED behavioural correlates (i.e. self-harm, history of suicide attempts, and psychiatric hospitalizations) was collected. In addition, between-groups analyses, linear regressions and machine learning (ML) models were used to identify ED predictors in each group. RESULTS: ED and its behavioural correlates were higher in ASC compared to NC, but milder than in BPD. While gender did not predict ED scores, autistic women had increased risk factors to ED, including sexual abuse and camouflaging. Interestingly, BPD traits, emotional vulnerability and alexithymia strongly predicted ED scores across the groups. Using ML models, sensory sensitivity and autistic camouflaging were associated with ED in ASC, and ADHD symptoms with ED in BPD. LIMITATIONS: ASC and BPD diagnoses were self-reported, which did not allow us to check their accuracy. Additionally, we did not explore the transactional and the moderating/mediating relationships between the different variables. Moreover, our research is cross-sectional and cannot draw conclusions regarding the direction and causality of relationships between ED and other clinical dimensions. CONCLUSIONS: ED and its behavioural correlates are heightened in BPD compared to ASC and nonclinical controls. In the ASC group, there were no gender differences in ED, despite the heightened exposure of autistic women to ED risk factors. BPD traits, emotional vulnerability, and alexithymia are core to ED regardless of diagnosis. Although less central, sensory sensitivity and autistic camouflaging seem to be specific predictors of ED in autistic adults.
