Psychotic symptoms in borderline personality disorder: an update

Borderline personality disorder vs. schizophrenia spectrum disorders in young people recruited within an "Early Intervention in Psychosis" service: clinical and outcome comparisons

Borderline Personality Disorder (BPD) is under-recognized in First-Episode Psychosis (FEP) and its psychotic manifestations are difficult to differentiate from Schizophrenia Spectrum Disorders (SSD). The aim of this investigation was to compare clinical, sociodemographic, and outcome characteristics between FEP patients with BPD vs. FEP subjects with SSD both at baseline and across a 2-year follow-up period. Participants completed the Health of the Nation Outcome Scale (HoNOS), the Positive And Negative Syndrome Scale (PANSS), and the Global Assessment of Functioning (GAF) scale both at entry and every 12 months during the follow-up. A mixed-design ANOVA model was conducted to investigate the temporal stability of clinical scores within and between the two subgroups. Among 356 FEP participants, 49 had a BPD diagnosis. Compared to FEP/SSD (n = 307), FEP/BPD patients showed higher prevalence of employment, current substance use, and past attempted suicide. They had a lower equivalent dose of antipsychotic medication at entry and lower levels of negative symptoms. Finally, they had a higher 2-year drop-out rate and a significant improvement in psychopathological scores limited to the first year of treatment. BPD as categorical entity represents a FEP subgroup with specific clinical challenges. Appropriate treatment guidelines for this FEP subgroup are thus needed.

The Subjective Experience of the Punitive Parent Mode in Individuals With Borderline Personality Disorder Following Schema Therapy: A Qualitative Study

Borderline personality disorder (BPD) is often characterized by self-critical and punitive thoughts, emotions, beliefs and behaviours, conceptualized in schema therapy (ST) as the punitive parent mode (PPM). This mode involves internalized punitive messages from childhood from the behaviour and reactions of significant others, leading to self-hatred, guilt and self-denial. Although patients with BPD frequently report auditory verbal hallucinations (AVHs) as manifestations of the PPM, this phenomenon is often overlooked in ST studies. We conducted semistructured interviews with 16 (ex)patients (63% female) from two Dutch mental health institutions to explore their experiences with the PPM before, during and after ST. An independent, double-coded systematic content analysis was performed. Approximately half of the participants reported AVHs linked to the PPM before therapy. The patients characterized the PPM by pervasive self-critical messages, contributing to intense emotional and physical distress and maladaptive coping strategies. Participants reported that ST techniques, including group therapy, imagery rescripting (ImRs) and the empty chair technique (ECT), effectively reduced the power and credibility of the PPM, including AVHs. The self-reported improvements included more adaptive coping mechanisms, increased social support and a general experience of reduced PPM. This study highlights the prevalence of the PPM as AVHs in individuals with BPD and demonstrates the efficacy of ST in reducing the impact of PPM, including in cases involving AVHs. Clinical implications include the need for relapse prevention plans and further exploration into how ST's effects can be enhanced. Future research should explore the broader spectrum of psychotic experiences in BPD and consider integrating PPM-related AVHs into the assessment and treatment of BPD.

Do help-seeking adolescents report more psychotic-like experiences than young adults on the 16-item version of the prodromal questionnaire (PQ-16)?

AIM

To compare psychotic-like experiences (PLEs) in adolescents and young adults referred to the Mental Health Services (MHSs).

METHODS

Participants scored the 16-item Prodromal Questionnaire (PQ-16) as part of the intake procedure. Data on the Diagnostic and Statistical Manual of Mental Disorders (DSM) classification and demographic data were collected.

RESULTS

The PQ-16 was completed by 13 783 respondents (mean age 24.63 years, SD = 6.09; 62.6% female). Overall, the scores on the PQ-16 were not higher for adolescents (11-17 years; m = 4.84, SD = 3.62) than for young adults (18-35 years; m = 5.47, SD = 3.85). On PQ-16 item level, adolescents reported seeing and hearing things more than adults did. Across all age groups, males scored lower on the PQ-16 than females. Specifically, adolescent males scored lower than other participants. For adolescents and young adults alike, PQ-16 scores were higher for participants with borderline personality disorder, PTSD, and mood disorder than for those with other DSM classifications.

CONCLUSIONS

Although help-seeking adolescents did not score higher on the PQ-16 than help-seeking young adults, more of them reported perceptual anomalies. Irrespective of age, participants with borderline personality disorder, PTSD and mood disorder scored higher on the PQ-16 than those with other DSM classifications.

Cognitive disturbances basic symptoms in help-seeking patients with borderline personality disorder: Characteristics and association with schizotypy

AIM

Although the presence of psychotic symptoms has been widely recognized in Borderline Personality Disorder (BPD), no study previously investigated cognitive Basic Symptoms (BS) and their clinical implications in patients with BPD.

METHODS

This cross-sectional study specifically examined the prevalence of COGDIS (cognitive disturbances) BS criteria in 93 help-seeking outpatients with BPD by using the Schizophrenia Proneness Instrument-Adult Version (SPI-A). We then explored associations of COGDIS with personality traits, functioning and core psychopathological features of BPD.

RESULTS

The prevalence rates of COGDIS criterion were 62.4%. BPD patients meeting COGDIS criteria reported higher levels of schizotypal personality traits, dissociative experiences and work/social functional impairment compared to individuals without COGDIS criteria. Furthermore, the number of cognitive BSs showed a positive correlation with severity levels of schizotypy.

CONCLUSIONS

Cognitive BS are common in BPD. Cognitive disturbances are associated with schizotypal personality traits and specific clinical features. The presence of cognitive BSs may identify a more severe subgroup of patients with BPD, potentially vulnerable to psychotic symptoms and reliably identifiable through assessment of schizotypal traits.

Elevated risk of sexually transmitted infections among adolescents and young adults with borderline personality disorder: a retrospective longitudinal nationwide population-based study

In this study, we examined the risk of sexually transmitted infections (STIs) among adolescents and young adults (AYAs) with borderline personality disorder (BPD). A total of 4649 AYAs with BPD and 46,490 age-, sex-, and socioeconomic-matched controls without BPD were enrolled from the National Health Insurance Research Database of Taiwan from 2001 to 2009 and were followed up until the end of 2011. Participants who contracted any STI during the follow-up period were identified. Cox regression analysis was conducted to examine the risk of contracting any STI among both patients and controls. A total of 4649 AYAs with BPD and 46,490 age-, sex-, and socioeconomic-matched controls without BPD were enrolled from the National Health Insurance Research Database of Taiwan from 2001 to 2009 and were followed up until the end of 2011. Participants who contracted any STI (ICD-9-CM code 042, 091-097, 087.11, 078.8, 078.88, 131, and 054.1) during the follow-up period were identified. Cox regression and sub-analyses stratified by sex, age, psychiatric comorbidity subgroups, and psychotropic medication usage were conducted to assess STI risk. AYAs with BPD were at a higher risk of contracting any STI (hazard ratio [HR] = 50.79, 95% confidence interval [CI] = 33.45-77.11) in comparison with controls, including HIV, syphilis, genital warts, gonorrhea, chlamydia, trichomoniasis, and genital herpes. The association of BPD with an increased risk of any STI was prevalent in both sexes, adolescents, and young adult patients. BPD with or without psychiatric comorbid subgroup were all associated with an elevated risk of contracting any STI relative to the control group. AYAs with BPD are highly susceptible to contracting STIs. Future studies should examine the role of the core symptoms of BPD, sexual orientation, risky sex behaviors, depressive and anxiety symptoms, and substance use before sex in the risk of STIs among AYAs with BPD.

The "Hysterical Psychosis" Dilemma: A Narrative Review

BACKGROUND

Hysteria in its most severe expression may reach psychotic manifestations. Such symptomatology has been occasionally described by various authors starting from the 19th century and defined as "hysterical psychosis" (HP) by Hollender and Hirsch in 1964. Currently, diagnostic psychiatric manuals such as DSM and ICD do not include the diagnosis of HP, although this term is commonly used in clinical practice. This raises a well-known problem with case definition due to an inconsistent use of terminology.

SUMMARY

Here, we propose a review of the literature that aims to highlight the clinical features of HP endorsed by the majority of authors, such as histrionic premorbid personality, acute reactive onset, short duration, altered state of consciousness, unstable delusions, typical hallucinations, labile mood, lack of flat affect. In the discussion, we focus on the differential diagnosis between HP and other diagnoses such as brief psychosis and schizophrenia, trying to point out aspects of distinction and continuity.

KEY MESSAGES

The debate about this nosographic entity still remains a huge dilemma and needs further contributions.

Psychotic Experiences and Daily Functioning in Borderline Personality Disorder and Schizophrenia

ABSTRACT

Psychotic experiences have been shown to be comparable in borderline personality disorder (BPD) and schizophrenia. Preliminary evidence suggests differences in the impact of psychotic experiences on daily functioning. Therefore, in this study, we aimed to investigate the role of psychotic experiences in daily functioning in BPD compared with schizophrenia. We performed post hoc analyses on data from 23 inpatients with BPD and 21 inpatients with schizophrenia, for whom results from the Psychotic Symptom Rating Scales were available. No differences were found in frequency, intensity, and disruption of life in relation to auditory verbal hallucinations and the amount of preoccupation and conviction with regard to delusions. Significant differences were found in the disruption of life due to delusions. The results emphasize that the quality of psychotic experiences in BPD and schizophrenia is comparable, but the impact of delusions on daily life is different, which may improve differential diagnosis.

The Diagnostic Spectrum of Sexual Hallucinations

ABSTRACT

Sexual hallucinations are little known, yet often extremely burdening, phenomena. In this systematic review, we summarize what is known about their phenomenology, prevalence, etiopathology, ensuing distress, and treatment options. Sexual hallucinations can be experienced as genital or orgasmic sensations, although other sensory modalities can also be involved. With the notable exception of orgasmic auras in the context of epilepsy, sexual hallucinations tend to be distressing and embarrassing in nature. Our analysis of 79 studies (together describing 390 patients) indicates that sexual hallucinations are more frequent in women than in men, with a sex ratio of 1.4:1, and that they are most prevalent in schizophrenia spectrum disorders, with rates ranging from 1.4% in recently admitted patients to 44% in chronically hospitalized patients. Other underlying conditions include epilepsy, the incubus phenomenon (possibly the most prevalent cause in the general population, associated with sleep paralysis), narcolepsy, and sedative use. As regards the sedative context, we found more medicolegal than purely medical cases, which sadly underlines that not all sexually explicit sensations experienced in anesthesia practice are indeed hallucinations. In the absence of evidence-based treatment protocols for sexual hallucinations, practice-based guidelines tend to focus on the underlying condition. Further research is needed, especially in the fields of substance abuse, posttraumatic stress disorder, and borderline personality disorder, where only anecdotal information on sexual hallucinations is available. Moreover, awareness of sexual hallucinations among health professionals needs to be improved in order to facilitate counseling, diagnosis, and treatment.

In search of hidden threats: A scoping review on paranoid presentations in personality disorders

Recent diagnostic developments suggest that paranoia is a transdiagnostic characteristic common to several personality disorders rather than a personality disorder per se. Nonetheless, empirical literature fails to provide comprehensive and univocal findings on whether and how paranoid presentations relate to different personality disorders. In the present scoping review, we map the empirical literature on paranoid presentations in personality disorders, considering the entire spectrum of paranoid manifestations (i.e., the paranoia hierarchy). In selecting original quantitative studies on paranoid presentations in personality-disordered patients, we screened 4,433 records in PsycArticles, PsycInfo and PUBMED. We eventually included 47 eligible studies in the review. Our synthesis indicates consistent empirical evidence of a wide range of paranoid presentations in Paranoid, Schizotypal and Borderline personality disorders. Conversely, little empirical literature exists on paranoid presentations in other personality disorders. Preliminary findings suggest broad-severity paranoid presentations, ranging from milder to severe forms, in Paranoid, Schizotypal and Borderline personality disorders. There is also some evidence of milder forms of paranoia in Avoidant, Antisocial and Narcissistic personality disorders. Conversely, there is poor evidence of paranoid presentations in Schizoid, Histrionic, Dependent or Obsessive-compulsive personality disorders. Research gaps and recommendations for improving empirical research on paranoid presentations in personality disorders are discussed.

Psychotic experiences, suicidality and non-suicidal self-injury in adolescents: Independent findings from two cohorts

BACKGROUND

Prior studies have shown that psychotic experiences are prospectively associated with an increased risk of suicidality. However, it is unclear whether this association is causal or arises from shared risk factors. Furthermore, little is known about the association between psychotic experiences and non-suicidal self-injury (NSSI).

METHODS

We used data from two independent samples of young adolescents, which we analyzed separately. In a population-based cohort, data on hallucinatory experiences and suicidality were collected at ages 10 and 14 years (N = 3435). In a cross-sectional study of a population oversampled for elevated psychopathology levels, psychotic experiences, suicidality, and NSSI were assessed at age 15 years (N = 910). Analyses were adjusted for sociodemographic covariates, maternal psychopathology, intelligence, childhood adversity, and mental health problems.

RESULTS

Psychotic experiences were prospectively associated with an increased risk of suicidality, even when considering self-harm ideation at baseline. Furthermore, persistent and incident, but not remittent, patterns of psychotic experiences were related to an increased burden of suicidality. Self-harm ideation was also prospectively associated with the risk for psychotic experiences, although of smaller magnitude and only by self-report. Among at-risk adolescents, psychotic experiences were cross-sectionally associated with a greater burden of suicidality and a higher frequency of NSSI events, with more extensive tissue damage.

CONCLUSION

Psychotic experiences are longitudinally associated with suicidality beyond the effects of shared risk factors. We also found modest support for reverse temporality, which warrants further investigation. Overall, our findings highlight the importance of assessing psychotic experiences as an index of risk for suicidality and NSSI.

Clinical Characteristics of Melancholic and Nonmelancholic Depressions

ABSTRACT

This study aimed to compare clinical-demographic features of melancholic and nonmelancholic depressions. We included 141 depressed inpatients classified as melancholic and nonmelancholic by the Sydney Melancholia Prototype Index (SMPI) and Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria. Results were controlled for confounders, including severity measures. Melancholic patients by both diagnostic systems were more severely depressed and presented more psychotic symptoms, neurological soft signs, and psychomotor disturbances. Melancholic patients classified by the SMPI were also older at illness onset and had fewer suicide attempts. After controlling for confounders, although all differences remained significant for SMPI diagnosis, the DSM-5 diagnosis of melancholia was only associated with further impaired motor sequencing. The results obtained with the SMPI support the hypothesis that melancholia has clinical features qualitatively different from those of nonmelancholic depressions. Contrarily, the DSM-5 specifier seems to reflect the severity of depressive episodes rather than core clinical features of melancholia.

Psychotic spectrum features in borderline and bipolar disorders within the scope of the DSM-5 section III personality traits: a case control study

BACKGROUND

Psychotic spectrum features in borderline personality disorder (PD) are a long-standing phenomenon, but remarkably, to date, they have not been the focus of many empirical studies. Moreover, the comparative studies that acknowledge their links to affective psychoses are even more scarce. Likewise, the contributions of empirical research on the DSM-5 dimensional approach to this topic are also uncommon. This study seeks to identify the best set of pathological personality traits and/or symptoms that are predictors of psychotic features (psychoticism and ideation paranoid symptoms) in borderline PD and in bipolar disorder, based on the framework of the DSM-5 section III personality traits.

METHODS

A cross-sectional study of two clinical samples: 1) Borderline PD group of 63 participants; 2) Bipolar disorder group of 65 participants. Self-reported assessment: Personality Inventory for DSM-5 (PID-5); Brief Symptom Inventory (BSI). A series of linear and logistic regression analyses were computed.

RESULTS

Overall, the data emerging as common predictors are detachment, negative affectivity, psychoticism, depressivity, grandiosity, suspiciousness and interpersonal sensitivity symptoms. Borderline PD has the highest score in BSI paranoid ideation which emerges as its discriminating trait (Nagelkerke R² = .58): cognitive and perceptual dysregulation (OR: 13.02), restricted affectivity (OR: 12.09), withdrawal (OR: 11.70), anhedonia (OR: 10.98) and emotional lability (OR: 6.69).

CONCLUSIONS

Besides the commonality that appears to overlap both disorders with a psychosis superspectrum, the patterns of the pathological personality-symptoms underlying the psychotic features appear to reinforce a position between schizophrenia and bipolar disorders that borderline PD may occupy, highlighting the possibility of its intersection with schizoaffective/psychosis spectra. The pathological personality nature of the psychotic features emerges as a potential comprehensive trait of the phenomenological dimensions.

Can you trust this source? Advice taking in borderline personality disorder

Research suggests that patients with borderline personality disorder (BPD) share a range of cognitive biases with patients with psychosis. As the disorder often manifests in dysfunctional social interactions, we assumed associated reasoning styles would be exaggerated in a social setting. For the present study, we applied the Judge-Advisor System by asking participants to provide initial estimates of a person's age and presumed hostility based on a portrait photo. Afterwards, we presented additional cues/advice in the form of responses by anonymous previous respondents. Participants could revise their estimate, seek additional advice, or make a decision. Contrary to our preregistered hypothesis, patients with BPD (n = 38) performed similarly to healthy controls (n = 30). Patients sought the same number of pieces of advice, were equally confident, and used advice in similar ways to revise their estimates. Thus, patients with BPD did trust advice. However, patients gave higher hostility ratings to the portrayed persons. In conclusion, patients with BPD showed no cognitive biases in seeking, evaluating, and integrating socially provided information. While the study implies emotional rather than cognitive biases in the disorder, cognitive biases may still prove to be useful treatment targets in order to encourage delaying and reflecting on extreme emotional responses in social interactions.

Mortality in psychotic depression: 18-year follow-up study

BACKGROUND

Evidence on the role of co-occurring psychiatric disorders in mortality associated with psychotic depression is limited.

AIMS

To estimate the risk of cause-specific mortality in psychotic depression compared with severe non-psychotic depression while controlling for comorbid psychiatric disorders.

METHOD

This cohort study used routine data from nationwide health registers in Finland. Eligible participants had their first diagnosis for psychotic depression or for severe non-psychotic depression between the years 2000 and 2018, had no pre-existing diagnoses for schizophrenia spectrum disorders or bipolar disorder, and were aged 18-65 years at the index diagnosis. Causes of death were defined by ICD-10 codes. The follow-up time was up to 18 years.

RESULTS

We included 19 064 individuals with incident psychotic depression and 90 877 individuals with incident non-psychotic depression. Half (1199/2188) of the deaths in those with psychotic depression occurred within 5 years from the index diagnosis and the highest relative risk was during the first year after the diagnosis. Compared with individuals with non-psychotic depression, those with psychotic depression had a higher risk of all-cause mortality (adjusted hazard ratio, aHR = 1.59, 95% CI 1.48-1.70), suicides (aHR = 2.36, 95% CI 2.11-2.64) and fatal accidents (aHR 1.63, 95% CI 1.26-2.10) during the subsequent 5-year period after the index diagnosis.

CONCLUSIONS

Psychotic symptoms markedly added to the mortality risk associated with severe depression after controlling for psychiatric comorbidity. Prompt treatment and enhanced monitoring for psychotic symptoms is warranted in all patients with severe depression to prevent deaths because of suicides and other external causes.

Understanding the inverse relationship between age and psychotic symptoms: The role of borderline personality traits

OBJECTIVE

There is a well-established inverse relationship between age and positive psychotic symptoms, both in patients with psychotic disorders and in general population samples with psychotic experiences. The reason for this inverse relationship is unclear. We hypothesized that life-course developmental changes in borderline personality traits, which also typically decline with age, might explain the inverse relationship between age and positive psychotic symptoms.

METHODS

We tested this hypothesis with data from 19,980 adults who completed 2000, 2007, and 2014 UK Adult Psychiatric Morbidity Survey studies. Hallucinations and delusions were assessed with the Psychosis Screening Questionnaire. Borderline features were assessed with the Structured Clinical Interview for DSM-IV Axis II Personality Disorders Screening Questionnaire. Logistic regression models with effect decompositions were used to conduct the analyses.

RESULTS

As expected, age was negatively associated with hallucinations and delusions. These effects were wholly or mostly reduced after controlling for borderline features. Similar results were found in a subgroup of participants with a probable psychotic disorder. Repeating the analysis with a broad index of psychopathology severity instead of borderline features did not produce comparable results. Borderline factor scores reflecting identity/relationship disturbance, mood instability/anger, and self-harm/suicidality were created, all of which appeared to explain part of the inverse relationship between age and psychotic experiences.

CONCLUSION

Declining borderline traits throughout adulthood may account for the reduced prevalence of positive psychotic symptoms in both clinical and non-clinical populations. Future research might evaluate the impact of treatments that target borderline traits on positive psychotic symptoms.

Irony detection in patients with borderline personality disorder: an experimental study examining schizotypal traits, response biases and empathy

BACKGROUND

In verbal irony we often convey meanings that oppose the literal words. To look behind these words, we need to integrate perspectives of ourselves, others, and their beliefs about us. Although patients with borderline personality disorder (BPD) experience problems in social cognition and schizotypal symptoms, research on irony comprehension mainly focused on the schizophrenic spectrum. Accounting for possible negative biases in BPD, the current study examined the detection of praising and critical irony in a text messaging interface.

METHODS

The cross-sectional study included 30 patients and 30 matched controls, who completed measures of cognitive and affective empathy (Interpersonal Reactivity Index, IRI), schizotypal (Schizotypal Personality Questionnaire; SPQ), and borderline symptoms (Borderline Symptom List; BSL-23) and the irony detection task. The irony task contained critical and praising remarks embedded in text messages. Asking for literality (ironic vs. literal) and intention ratings (critical to praising) of the stimuli, it allowed to analyze the sensitivity of literality detection as well as implicit and explicit response biases in a signal detection framework.

RESULTS

Borderline symptoms explained lower sensitivity for the detection of literal and ironic statements across groups. Whereas HC showed a negativity bias when implicitly asked about the literalness of the statement, patients with BPD perceived praising utterances as less praising when explicitly asked about their perceived intention. Neither empathy nor schizotypy explained outcomes beyond borderline symptoms.

CONCLUSIONS

This was the first study to show lower detection of verbal irony in patients with BPD. While patients were less biased when asked about the literality of a statement, they perceived praising remarks as less positive on explicit measurements. The results highlight the importance of congruent, transparent communication in promoting epistemic trust in individuals with BPD.

Comparison of the Phenomenology of Hallucination and Delusion Characteristics in People Diagnosed With Borderline Personality Disorder and Schizophrenia

Hallucinations and delusions in borderline personality disorder (BPD) are understudied. The authors explore the phenomenology of multisensory hallucinations and delusions in individuals with BPD and compare them to those in individuals with schizophrenia spectrum disorders (SSD). Clinical psychopathology was also explored. Eighty-nine adults participated and were categorized into four groups: BPD with voices, BPD without voices, SSD with high BPD traits, and SSD with low BPD traits. Among individuals with BPD, 81% reported visual and tactile hallucinations, 75% reported olfactory hallucinations, and 94% experienced delusions. When comparing BPD with and without voices, there were no significant differences in nonpsychotic psychopathology. Slight differences were found when hallucinations in BPD were compared with hallucinations in SSD, but overall the experiences were similar across diagnoses. The BPD group also reported significantly higher rates of paranoia/suspiciousness and delusions of guilt than the SSD group. Multisensory hallucinations and delusions occur in BPD and should be explored when treating people with BPD.

Recruiting and exploring vulnerabilities among young people at risk, or in the early stages of serious mental illness (borderline personality disorder and first episode psychosis)

INTRODUCTION

Many gaps exist in our understanding of the developmental pathways to severe mental illness (SMI), including borderline personality disorder (BPD) and psychosis. However, those who have experienced adverse childhood experiences (ACEs) are at an increased risk and there is evidence to suggest that one of the earliest markers is emotional dysregulation. An area which has received relatively less research attention is the role neurodevelopmental disorders (NDDs) play. The aim of this feasibility study was therefore to explore the clinical profiles of young people early in the course of SMI, including their profiles of ACEs, emotional regulation difficulties, borderline personality traits and NDDs.

METHODS

A cross-sectional study of young people (aged 15-25) at risk of SMI, currently being seen within NHS mental health services, was conducted. This included those with early symptoms of psychosis and/or BPD as assessed by diagnostic interview. Eligible participants self-completed a battery of sociodemographic, clinical, and psychological measures in the company of a researcher. This included assessments of: symptoms of NDDs; borderline pathology traits; ACEs; and difficulties in emotional regulation. Statistical analyses included Mann-Whitney U tests and multiple regression.

RESULTS

Of the 118 potentially eligible participants who were referred, 48 were ultimately included in the study. Young people early in the course of SMI reported a high prevalence of ACEs and deficits in emotional regulation. In total, 79% met criteria for attention deficit hyperactivity disorder (ADHD) and/or autism spectrum disorder (ASD). Emotional dysregulation was found to significantly mediate the association between both ACEs and the frequency of NDDs and borderline personality traits, however given the small sample size these results are preliminary in nature.

CONCLUSION

Young people early in the course of SMI are at an increased risk of experiencing multiple childhood adversities and our results indicate a high prevalence of NDDs amongst them. Emotional dysregulation emerged as a potentially significant early marker of future clinical severity. We suggest that the clinical implications of our findings include routine screening for NDDs and ACEs and an increased recognition of the significance of emotional dysregulation. However, larger scale longitudinal studies are needed to investigate these preliminary findings further.

Paranoia in patients attending child and adolescent mental health services

OBJECTIVE

Paranoia may be particularly prevalent during adolescence, building on the heightened social vulnerabilities at this age. Excessive mistrust may be corrosive for adolescent social relationships, especially in the context of mental health disorders. We set out to examine the prevalence, symptom associations, and persistence of paranoia in a cohort of young people attending child and adolescent mental health services.

METHOD

A total of 301 patients (11-17 years old) completed measures of paranoia, affect, peer difficulties and behavioural problems. Clinicians also rated each participant's psychiatric symptoms. Patterns of association were examined using linear regressions and network analyses. In total, 105 patients repeated the measures several months later.

RESULTS

Most of the adolescents had affective disorders (n = 195), self-harm/suicidality (n = 82), or neurodevelopmental conditions (n = 125). Few had suspected psychosis (n = 7). Rates of paranoia were approximately double compared with previous reports from the general population. In this patient sample, 35% had at least elevated paranoia, 15% had at least moderate paranoia, and 6% had high paranoia. Paranoia had moderate associations with clinician-rated peer difficulties, self-harm, and trauma, and small associations with clinician-rated social anxiety, depression, generalised anxiety, and educational problems. Network analyses showed paranoia had the strongest unique relationship with peer difficulties. Paths from peer difficulties to anxiety, self-harm, post-traumatic stress disorder symptoms, and behavioural problems were all via paranoia. Both self-harm and post-traumatic stress disorder were solely associated with paranoia in the network. Paranoia remained persistent for three-quarters and was associated with greater psychological problems over time.

CONCLUSION

Paranoia is relatively common and persistent across a range of clinical presentations in youth. When paranoia occurs alongside emotional problems, important peer interactions may be adversely affected. Wider consideration of paranoia in adolescent patients is needed.

In light of the DSM-5 dimensional model of personality: Borderline personality disorder at the crossroads with the bipolar spectrum

BACKGROUND

State-of-the-art research highlights that borderline personality disorder (PD) and bipolar spectrum disorders have clinical characteristics in common, which imply uncertainty in differential diagnoses. Although there is a growing body of literature on the DSM-5 dimensional model of personality disorder, its discriminative features between these clinical samples are still understudied. In this study, we seek to identify the best set of predictors that differentiate between borderline PD and bipolar spectrum, based on pathological and normative personality traits and symptoms.

METHODS

A cross-sectional study of three clinical samples: 1) Borderline PD group of 63 participants; 2) Major depressive disorder group of 89 participants; 3) Bipolar disorder group of 65 participants. Self-reported assessment: Personality Inventory for DSM-5; Brief Symptom Inventory; FFM Inventory. A series of one-way ANOVAs and logistic regression analyses were computed.

RESULTS

The major set of data emerging as common discriminants of borderline PD across the bipolar spectrum are unusual beliefs & experiences, paranoid ideation, obsession-compulsion and extraversion. Depressivity (OR: 34.95) and impulsivity (OR: 22.35) pathological traits displayed the greatest predictive values in the differential diagnosis.

LIMITATIONS

The small size of the samples; a lack of data from participants' previous clinical history.

CONCLUSIONS

Findings support the DSM-5 pathological traits as differentiating borderline PD through bipolar spectrum, and reinforcing the joint use of symptom-related pathological functioning and normal-range personality traits. Alongside the bipolar spectrum, borderline pathology sheds light upon a hypothetical overlap along the depressive and schizoaffective/schizophrenia spectra, representing a borderland space at a crossroads with the psychopathology of a meta-spectrum.

An Eye Tracking Study on Feigned Schizophrenia

Research on malingering detection has not yet taken full advantage of eye tracking technology. In particular, while several studies indicate that patients with schizophrenia behave notably differently from controls on specific oculomotor tasks, no study has yet investigated whether experimental participants instructed to feign could reproduce those behaviors, if coached to do so. Due to the automatic nature of eye movements, we anticipated that eye tracking analyses would help detect feigned schizophrenic problems. To test this hypothesis, we recorded the eye movements of 83 adult UK volunteers, and tested whether eye movements of healthy volunteers instructed to feign schizophrenia (n = 43) would differ from those of honest controls (n = 40), while engaging in smooth pursuit and pro- and anti-saccade tasks. Additionally, results from our investigation were also compared against previously published data observed in patients with schizophrenia performing similar oculomotor tasks. Data analysis showed that eye movements of experimental participants instructed to feign (a) only partially differed from those of controls and (b) did not closely resemble those from patients with schizophrenia reported in previously published papers. Taken together, these results suggest that examination of eye movements does have the potential to help detecting feigned schizophrenia.

Off-label use of second-generation antipsychotics in borderline personality disorder: a comparative real-world study among oral and long-acting injectables in Spain

The aim of the present study was to evaluate the use of oral vs. long-acting injectables (LAIs) antipsychotics, as well as, to compare the effectiveness of different LAI antipsychotics [aripiprazole-1-month, paliperidone-1-month (PP1M), paliperidone-3-month (PP3M) and risperidone long-acting injectable (RLAI)] in patients diagnosed with borderline personality disorder (BPD), by evaluating the following clinical outcomes: (1) the number of hospital admissions; (2) the number of documented suicidal behaviour/attempts; and (3) the use of concomitant treatments, including benzodiazepines, oral antipsychotics and biperiden. We included a total of 116 patients diagnosed with BPD and treated with antipsychotic medication: 50 using a LAI antipsychotic formulation and 66 using the equivalent main oral antipsychotic. Patients treated with LAIs showed a decreased ratio of visits to emergency compared with the oral treatment group, and between LAIs, PP3M vs. aripiprazole-1-month group. Furthermore, patients treated with LAIs used lower number and dose of concomitant antipsychotics compared with patients treated with oral antipsychotics. Moreover, PP1M and PP3M used lower daily dose of diazepam equivalents compared with the aripiprazole-1-month and RLAI treatment groups. In conclusion, the use of LAIs may play a role in the management of BPD.

Schizophrenia-schizoaffective-bipolar spectra: an epistemological perspective

For decades clinicians and researchers have been thinking and writing about the spectrum of schizophrenia disorders. Indeed both Kraepelin and Bleuler believed in schizophrenia as a spectrum, both in a clinical (individual) and hereditary (family) continuum, from just some exquisite personality traits to unquestionable chronic and debilitating psychosis. Other authors would put the schizophrenia spectrum disorders on different levels of continuum: developmental, psychofunctional, existential, and genetic. Here, we would like to present an historical chronology for the schizophrenia-schizoaffective-bipolar spectra plus a tridimensional model for these spectra: the first axis for categories (affective versus nonaffective psychoses), the second axis for dimensions (personality versus full blown psychosis), and a third axis for biomarkers (remission versus relapse). We believe that without the schizophrenia-schizoaffective-bipolar spectra concept in our minds all our efforts will keep failing one the hardest quest: searching for biomarkers in schizophrenia and related disorders.

How does level of personality functioning inform clinical management and treatment? Implications for ICD-11 classification of personality disorder severity

PURPOSE OF REVIEW

The International Classification of Diseases, 11th Edition (ICD-11) classifies personality disturbance according to levels of severity. This article reviews the literature on levels of personality functioning in relation to clinical management and treatment, and proposes how these findings apply to the ICD-11 classification of personality disorders.

RECENT FINDINGS

Findings were primarily derived from studies using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) Level of Personality Functioning Scale (LPFS), Kernberg's Level of Personality Organization, and the general P-factor of personality disorder. Severity of personality dysfunction is related to treatment outcome, risk of dropout, therapeutic alliance, readiness for treatment, risk of harm to self or others, risk of dissociation and psychotic-like breaks, coherence in narrative identity, reflective functioning, and epistemic trust.

SUMMARY

The overall level of personality disorder severity indicates risk of negative outcomes and may be used as decision tool for 'personalized medicine' and required treatment intensity (e.g., strength of alliance and the need for establishing epistemic trust). Beyond the ICD-11 guidelines for determining personality disorder severity, these implications also apply to practitioners using comparable frameworks such as the DSM-5 LPFS and Kernberg's Level of Personality Organization. Future research should focus on the interaction of severity with trait qualifiers in relation to clinical management.

Association of Parent-Reported Sleep Problems in Early Childhood With Psychotic and Borderline Personality Disorder Symptoms in Adolescence

IMPORTANCE

Persistent nightmares in childhood have been prospectively associated with psychosis and borderline personality disorder (BPD) in adolescence. However, the extent to which this association is also true for behavioral sleep problems is still unknown, and the potential mechanisms are unexplored.

OBJECTIVE

To examine the prospective associations between several parent-reported sleep problems in early childhood and psychotic and BPD symptoms at 11 to 13 years of age and the potential mediation of the associations by depression at 10 years of age.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study assessed 13 488 participants in the Avon Longitudinal Study of Parents and Children birth cohort who were followed up for more than 13 years. Pregnant women from Avon, United Kingdom, with expected dates of delivery from April 1, 1991, to December 31, 1992, were invited to take part in the study. Data analysis was conducted from May 1 to December 31, 2019.

MAIN OUTCOMES AND MEASURES

Psychotic experiences at 12 to 13 years of age were assessed using the Psychosis-Like Symptom Interview, and BPD symptoms at 11 to 12 years of age were tested using the UK Childhood Interview for DSM-IV Borderline Personality Disorder. Parent-reported nighttime sleep duration, night awakening frequency, bedtime, and regularity of sleep routines were assessed when the child was 6, 18, and 30 months and 3.5, 4.8, and 5.8 years of age.

RESULTS

Data were available on 7155 participants (3718 girls [52%]) who reported on BPD symptoms and 6333 (3280 boys [52%]) who reported on BPD symptoms. Higher night awakening frequency at 18 months of age (odds ratio [OR], 1.13; 95% CI, 1.01-1.26) and less regular sleep routines at 6 months (OR, 0.68; 95% CI, 0.50-0.93), 30 months (OR, 0.64; 95% CI, 0.44-0.95), and 5.8 years (OR, 0.32; 95% CI, 0.19-0.53) of age were significantly associated with psychotic experiences in adolescence, whereas shorter nighttime sleep duration (OR, 0.78; 95% CI, 0.66-0.92) and later bedtime at 3.5 years of age (OR, 1.32; 95% CI, 1.09-1.60) were significantly associated with BPD symptoms. Results of mediation analysis were consistent with all these associations, except for later bedtime at 3.5 years and BPD in adolescence, which had no association. Depression at 10 years of age mediated the associations between frequent night awakenings at 18 months of age (bias-corrected estimate, -0.005; 95% CI, -0.008 to -0.002; P = .002) and irregular sleep routines at 5.8 years of age (bias-corrected estimate, -0.006; 95% CI, -0.010 to -0.003; P = .003) with psychosis.

CONCLUSIONS AND RELEVANCE

The findings suggest that some behavioral sleep problems in childhood are distinctively associated with the onset of psychosis and BPD in adolescence, following different pathways. Furthermore, depression at 10 years of age may mediate only the association with psychosis. These findings contribute to the design of more personalized interventions in psychosis and BPD.

Familiarity, empathy and comprehension of metaphors in patients with borderline personality disorder

Research on figurative language has a long tradition in psychiatry, as it is employed in psychotherapy and its (mis)comprehension plays a substantial role in differential diagnostics of schizophrenic spectrum disorders. Although often associated with empathy and mentalization, it has never been addressed in borderline personality disorder (BPD). Therefore, this study investigated metaphor comprehension and its relationship to cognitive and affective empathy in 20 patients with BPD and 20 matched healthy controls who completed a metaphor task comprising conventional metaphors (CM), novel metaphors (NM), meaningless stimuli (MS), and a rating scale of familiarity, a factor known to influence performance. For cognitive and affective empathy, the interpersonal reactivity index was applied. At first patients with BPD seemed to have significantly more problems in comprehending CM, but not NM or MS, and were less familiar with CM. When familiarity with the stimulus was controlled, this difference disappeared. As for empathy, only fantasy was positively related to familiar CM beyond borderline symptoms. Results indicate that the comprehension of novel metaphorical meaning is preserved in patients with BPD.

Testing the Interpersonal-Cognitive Model of Auditory Verbal Hallucinations in Youths with Either Early-Stage Borderline Personality Disorder or First-Episode Schizophrenia Spectrum Disorder

This is the first study to explore interpersonal schemata in outpatient youths (age 15-25 years) with early-stage borderline personality disorder (BPD) and auditory verbal hallucinations (AVH). It also aimed to replicate, in a transdiagnostic youth sample, the finding from studies of adults with AVH that negative beliefs about the self and others lead to negative appraisals of voices, which in turn elicits depression. The following 3 groups were compared: youth with BPD+AVH (n = 23), youth with schizophrenia spectrum disorder (SZ) with AVH (SZ+AVH, n = 20), and youths with BPD who did not experience AVH (BPD no AVH, n = 23). The BPD+AVH group reported more negative and fewer positive self schemata than the SZ+AVH group. They also saw themselves as being more socially inferior to others than did the SZ+AVH group, but they did not differ in appraisals of self or others, compared with the BPD no AVH group. In youths with AVH (BPD+AVH, SZ+AVH combined), the indirect effect of beliefs about self or others, via negative appraisals of voices on depression, was not significant. Instead, a significant indirect effect of negative appraisals of voices on depression, via negative beliefs about self, was found. The experience of AVH during adolescence and young adulthood, when the identity is still being formed, might have a more profound effect on the developing self than during later adulthood, when the self is more stable and resilient. Negative self-appraisals might constitute a treatment target for early intervention for youths with distressing voices, including those with BPD.

Avoiding Misdiagnosis When Auditory Verbal Hallucinations Are Present in Borderline Personality Disorder

Misdiagnosis is common for patients with a primary diagnosis of borderline personality disorder (BPD) who experience auditory verbal hallucinations (AVHs). AVHs in BPD are associated with severe BPD and high levels of suicidality. Wrongly treating these patients as though they are suffering from schizophrenia or other primary psychotic disorder and not treating BPD can cause significant iatrogenic damage. We outline a specific pattern of symptoms and phenomenology that will assist diagnostic accuracy in these cases. A focused review identified the following characteristic pattern: AVHs in BPD cannot be distinguished phenomenologically from AVH in schizophrenia, often meet the criteria for First-Rank Symptoms (FRSs), are highly stress related, and are strongly associated with dissociative experiences and childhood trauma. Formal thought disorder is uncommon, negative symptoms are usually absent, bizarre delusions are absent, affect remains reactive, and sociability is usually retained. Diagnostic accuracy can be improved by examining the overall clinical presentation and is essential to improving the prognosis for these patients.

Is adjunctive CBT really effective for schizophrenia?

Although antipsychotic medication remains the mainstay of treatment for schizophrenia, medications alone are not always successful. Cognitive–behavioural therapy (CBT) is recommended as an adjunct to pharmacological treatment. The Cochrane review under consideration evaluates the effects of offering CBT as an add-on to standard care compared with standard care alone, and this commentary puts those findings into their clinical context.

DECLARATION OF INTEREST

None.

Autism and psychosis as diametrical disorders of embodiment

Humans have evolved an elaborate system of self-consciousness, self-identity, self-agency, and self-embodiment that is grounded in specific neurological structures including an expanded insula. Instantiation of the bodily self has been most-extensively studied via the 'rubber hand illusion', whereby parallel stimulation of a hidden true hand, and a viewed false hand, leads to the felt belief that the false hand is one's own. Autism and schizophrenia have both long been regarded as conditions centrally involving altered development of the self, but they have yet to be compared directly with regard to the self and embodiment. Here, we synthesize the embodied cognition literature for these and related conditions, and describe evidence that these two sets of disorders exhibit opposite susceptibilities from typical individuals to the rubber hand illusion: reduced on the autism spectrum and increased in schizophrenia and other psychotic-affective conditions. Moreover, the opposite illusion effects are mediated by a consilient set of associated phenomena, including empathy, interoception, anorexia risk and phenotypes, and patterns of genetic correlation. Taken together, these findings: (i) support the diametric model of autism and psychotic-affective disorders, (ii) implicate the adaptive human system of self-embodiment, and its neural bases, in neurodevelopmental disorders, and suggest new therapies and (iii) experimentally ground Bayesian predictive coding models with regard to autism compared with psychosis. Lay summary: Humans have evolved a highly developed sense of self and perception of one's own body. The 'rubber hand illusion' can be used to test individual variation in sense of self, relative to connection with others. We show that this illusion is reduced in autism spectrum disorders, and increased in psychotic and mood disorders. These findings have important implications for understanding and treatment of mental disorders.

Preliminary Evidence for the Cognitive Model of Auditory Verbal Hallucinations in Youth With Borderline Personality Disorder

Objectives: This is the first study to explore cognitive, emotional, and behavioral responses to voices in youth with borderline personality disorder (BPD) compared with those with schizophrenia spectrum disorder (SZ), and to examine if negative appraisals of voices predict depression and anxiety across the groups. Methods: The sample comprised 43 outpatients, aged 15-25 years, who reported auditory verbal hallucinations (AVH) and were diagnosed with either Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) BPD or SZ. Data were collected using the Psychotic Symptom Rating Scales, the revised Beliefs About Voices Questionnaire, the Voice Rank Scale, and the Depression Anxiety Stress Scale. Results: Youth with BPD did not differ from youth with SZ in beliefs about the benevolence or malevolence of voices. Youth with BPD appraised their voices as more omnipotent and of higher social rank in relation to themselves, compared with youth with SZ. In both diagnostic groups, beliefs about malevolence and omnipotence of voices were correlated with more resistance toward voices, and beliefs about benevolence with more engagement with voices. In addition, perceiving the voices as being of higher social rank than oneself and negative voice content were both independent predictors of depression, irrespective of diagnostic group. In contrast, negative appraisals of voices did not predict anxiety after adjusting for negative voice content. Conclusions: This study replicated the link between negative appraisals of voices and depression that has been found in adults with SZ in a mixed diagnostic youth sample. It, thus, provides preliminary evidence that the cognitive model of AVH can be applied to understanding and treating voices in youth with BPD.
