Individuals with Borderline Personality Disorder manifest cognitive biases implicated in psychosis

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.

How does framing influence preference for multiple solutions to societal problems?

Solutions to environmental and social problems are often framed in dichotomous ways, which can be counterproductive. Instead, multiple solutions are often needed to fully address these problems. Here we examine how framing influences people's preference for multiple solutions. In a pre-registered experiment, participants (N = 1,432) were randomly assigned to one of four framing conditions. In the first three conditions, participants were presented with a series of eight problems, each framed with multiple causes, multiple impacts, or multiple solutions to the problem. The control condition did not present any framing information. Participants indicated their preferred solution, perceived severity and urgency of the problem, and their dichotomous thinking tendency. Pre-registered analyses showed that none of the three frames had a significant impact on preference for multiple solutions, perceived severity, perceived urgency, or dichotomous thinking. However, exploratory analyses showed that perceived severity and urgency of the problem were positively correlated with people's preference for multiple solutions, while dichotomous thinking was negatively correlated. These findings showed no demonstrable impact of framing on multi-solution preference. Future interventions should focus on addressing perceived severity and urgency, or decreasing dichotomous thinking to encourage people to adopt multiple solutions to address complex environmental and social problems.

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.

Effects of gender and psychiatric comorbidity on the age of illness onset and the outcome of psychotic depression-A birth cohort study

BACKGROUND

Psychotic depression (PD) is an under-researched disorder with severe symptoms and course of illness. Little is known about gender differences relating to this condition and possible variation of prognosis based on comorbid pathology. Our aim was to analyze the effects of gender and psychiatric comorbidities on the age of illness onset and on the outcome of psychotic depression.

METHODS

The study was carried out in the Northern Finland Birth Cohort 1966. We utilized register data to acquire information about lifetime psychiatric diagnoses, hospitalization, age of illness onset, rate of disability pensions and mortality. The PD group (n = 58) was defined based on a lifetime register diagnosis. We compared outcome variables in sub-groups based on gender and comorbid alcohol use or personality disorder.

RESULTS

The prevalence of comorbid personality disorders was 38% (22/58) and comorbid alcohol use disorders 41% (24/58). PD patients with a personality disorder diagnosis had an earlier onset age (p<0.01) and a higher mortality rate (p = 0.03). Male gender (p = 0.03), comorbid alcohol use disorder (p<0.01) and personality disorder (p < 0.01) were all associated with more psychiatric hospitalization. Comorbid alcohol use disorder was more common among men (males: 61%; females: 29%; p = 0.03).

LIMITATIONS

National registers were the main source of diagnostic information.

CONCLUSIONS

Gender and psychiatric comorbidity have significant implications for the course of illness in PD in naturalistic settings, which is an important message for all clinicians. More research into the heterogeneity of PD is needed in order to guide research and clinical practice.

Jumping to conclusions and suicidal behavior in depression and psychosis

Suicidal behavior (SB) involves an impairment in decision-making (DM). Jumping to conclusions bias (JTC), described as the tendency to make hasty decisions based on insufficient information, could be considered as analogous of impaired DM. However, the link between JTC and SB in psychosis and other diagnoses (e.g., depression) has never been studied. This study aims to explore the presence of JTC and SB in a sample comprising 121 patients with psychosis and 101 with depression. Sociodemographic and clinical data were collected, including history of SB and symptom-severity scores. JTC was assessed by the beads task, and patients who reached decisions with the second bead or before were considered to exhibit JTC. Age, gender, diagnosis, educational level, symptom severity, substance use, and SB were compared according to JTC presence. Variables found to be significantly different in this comparison were included in a multivariate analysis. JTC was more prevalent in patients with depression than with psychosis: 55.6% in an 85:15 ratio and 64.6% in a 60:40 ratio. When multivariate logistic regression was applied to study the influence of diagnosis (psychosis versus depression), age, and SB, only SB remained statistically significant (OR 2.05; 95% CI 0.99-4.22; p = 0.05). The population studied was assembled by grouping different samples from previous research, and we have not included control variables such as other clinical variables, neurocognitive measurements, or personality traits. JTC may be more closely linked to SB, as a transdiagnostic variable, rather than to a specific diagnosis.

Evaluating schema modes and cognitive distortions in borderline personality disorder: A mixed-method approach

OBJECTIVES

Cognitive processes, such as schema modes and cognitive distortions, may play a role in the genesis and maintenance of affective, interpersonal, and behavioral difficulties in individuals with Borderline Personality Disorder (BPD). This study aimed at exploring the schema modes and cognitive distortions in individuals with BPD.

METHODS

Using a mixed-method approach, 30 individuals with BPD and 30 healthy participants were assessed on the Borderline Personality Questionnaire, the Schema Mode Inventory, the Cognitive Distortions Scale, and a semi-structured interview schedule.

RESULTS

The BPD group had higher scores than the control group on all the maladaptive schema modes and cognitive distortions subscales. The child modes were the commonest and were also the strongest correlate of BPD symptomatology. Qualitative analysis of the content of the semi-structured interview also corroborated these findings.

CONCLUSIONS

There could be many schema modes and cognitive distortions operating behind the diverse psychopathology seen in 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.

Identity pathology and borderline personality disorder: an empirical overview

Pathological identity-related functioning is a core feature of borderline personality disorder (BPD) that is grievously underrepresented in the empirical literature. Burgeoning evidence indicates that identity pathology is multifaceted, influenced by transactions between social and endogenous processes, and associated with a wide variety of maladaptive outcomes. Although historically defined by patterns of instability (e.g. frequent and rapid changes to career goals, religious beliefs, core values, friend groups, etc.), accumulating research indicates that identity pathology also manifests as distress and functional impairment related to excessive rigidity (i.e. unrelenting negative self-evaluations; overidentification with a restricted role or group membership) and/or incongruous behavior (i.e. simultaneously holding discordant beliefs/values/attitudes, actions that are grossly contradictory with values, incoherent sense of self, etc.). Despite the complex nature of this construct, and its centrality to BPD, researchers often assess identity pathology indirectly, inadequately, or fail to measure it entirely. In this article, we briefly describe how identity pathology may fit into etiological models of BPD, highlight emerging themes from recent research, and identify important gaps in our knowledge. We also discuss limitations associated with current assessment practices, recommend alternatives, and articulate a research agenda for the future.
