Validation of the Basic Empathy Scale in an Arabic-speaking population: The BES-Ar.

PURPOSE: The aim of this work was to test the psychometric properties of the Arabic version of the BES (Basic Empathy Scale) by establishing its factor structure, its internal consistency and construct validity in the general population. DESIGN AND METHODS: The BES was tested among 526 Tunisian adults. FINDINGS: The two-factor structure of the BES-20 was confirmed. Internal consistency and concurrent validity were very satisfactory. DISCUSSION: This scale will be useful for clinicians in various fields (mental health, psychiatry) in Arabic countries.

Positive and negative urgency as a single coherent construct: Evidence from a large-scale network analysis in clinical and non-clinical samples.

AIMS: Negative and positive urgency are emotion-related impulsivity traits that are thought to be transdiagnostic factors in psychopathology. However, it has recently been claimed that these two traits are closely related to each other and that considering them separately might have limited conceptual and methodological value. The present study aimed to examine whether positive and negative urgency constructs constitute separate impulsivity traits. METHODS: In contrast to previous studies that have used latent variable approaches, this study employed an item-based network analysis conducted in two different samples: a large sample of non-clinical participants (N = 18,568) and a sample of clinical participants with psychiatric disorders (N = 385). RESULTS: The network analysis demonstrated that items denoting both positive and negative urgency cohere as a single cluster of items termed "general urgency" in both clinical and non-clinical samples, thereby suggesting that differentiating positive and negative urgency as separate constructs is not necessary. CONCLUSION: These findings have important implications for the conceptualization and assessment of urgency and, more broadly, for future research on impulsivity, personality, and psychopathology.

Modulation of the N400 component in relation to hypomanic personality traits in a word meaning ambiguity resolution task.

AIM: High levels of hypomanic personality traits have been associated with an increased risk of developing bipolar disorder (BD). Changes in semantic content, impaired verbal associations, abnormal prosody, and abnormal speed of language are core features of BD, and are thought to be related to semantic processing abnormalities. In the present study, we used event-related potentials to investigate the relation between semantic processing (N400 component) and hypomanic personality traits. METHODS: We assessed 65 healthy young adults on the Hypomanic Personality Scale (HPS). Event-related potentials were recorded during a semantic ambiguity resolution task exploring semantic ambiguity (polysemous word ending a sentence) and congruency (target word semantically related to the sentence). RESULTS: As expected, semantic ambiguity and congruency both elicited an N400 effect across our sample. Correlation analyses showed a significant positive relationship between the Social Vitality subscore of the HPS and N400 modulation in the frontal region of interest in the incongruent unambiguous condition, and in the frontocentral region of interest in the incongruent ambiguous condition. CONCLUSION: We found differences in semantic processing (i.e., detection of incongruence and semantic inhibition) in individuals with higher Social Vitality subscores. In the light of the literature, we discuss the notion that a semantic processing impairment could be a potential marker of vulnerability to BD, and one that needs to be explored further in this clinical population.

Electrophysiological correlates of emotional meaning in context in relation to facets of schizotypal personality traits: A dimensional study.

AIMS: The aim of this study was to investigate the neurocognitive processes mediating the processing of emotional information during the integration of contextual and social information in a schizotypal population. METHODS: One hundred and thirty-one healthy participants were evaluated using the Schizotypal Personality Questionnaire and event-related potentials were recorded during a linguistic task in which participants read sentence pairs describing short social situations to themselves. The first sentence implicitly conveyed the positive or negative emotional state of a character. The second sentence was emotionally congruent or incongruent with the first sentence. RESULTS: Across our overall sample, our results revealed a greater N400 effect at right sites than left sites, whereas the late positive component effect was only observed at left sites. Concerning the correlation results, we observed a negative link between positive and global schizotypy and N400 modulation in response to congruent targets for positive context sentences. Results also showed a positive correlation between negative schizotypy and late positive component modulation in response to congruent targets for negative context sentences. CONCLUSIONS: These results suggest that the different facets of the schizotypal personality traits influenced the integration of emotional context at the level of both early and later-mobilized neurocognitive processes.

The Basic Empathy Scale adapted to French middle childhood: Structure and development of empathy.

We adapted the adult French version of the Basic Empathy Scale to French children aged 6-11 years, in order to probe the factorial structure underlying empathy. A total of 410 children (189 girls and 221 boys) were instructed to fill out the resulting Basic Empathy Scale in Children (BES-C). Results showed that, as in adulthood, the three-factor model of empathy (i.e., emotional contagion, cognitive empathy, and emotional disconnection) was more relevant than the one- and two-factor ones. This means that as early as 6 years of age, children's responses should reflect the same organization of the three components of empathy as those of adults. In line with the literature, cognitive empathy increased and emotional disconnection decreased in middle childhood, while emotional contagion remained stable. Moreover, girls exhibited greater emotional contagion than boys, with the reverse pattern being observed for emotional disconnection. No sex difference was found regarding cognitive empathy.

Factor structure of the French version of the Hypomanic Personality Scale (HPS) in non-clinical young adults.

BACKGROUND: Hypomanic Personality Scale (HPS) is a self-report questionnaire designed to identify vulnerable individuals at high risk of bipolar disorders in non-clinical samples. Our aim was to identify the factorial structure of HPS in a French non-clinical sample and to compare this with different factor solutions described in the literature. We carried out a survey in a French population using a French version of HPS. METHODS: A total of 698 participants were included in the study. They completed the HPS, the Schizotypal Personality Questionnaire-Brief (SPQ-B), the Positive And Negative Affect Schedule (PANAS), and the Beck Depression Inventory (BDI-II). We tested the 1, 3 and 4-factor solutions and used a Confirmatory Factor Analysis to compare these with the factor solutions suggested by Rawling et al. and Schalet et al. RESULTS: Goodness-of-fit indices showed that Schalet et al.'s solution "fits" our data better than Rawling et al.'s factorial solutions. HPS scores correlated with the PANAS Positive score and the SPQ-B total score. We confirmed the 3-factor structure of the HPS in a large non-clinical population of young adults and found consistent correlations with BDI, affectivity and schizotypal traits.

Impaired conscious memory in non-clinical schizotypy.

INTRODUCTION: Impaired controlled and preserved/enhanced automatic memory processes have been reported in schizotypy. This memory pattern has been considered as a marker of vulnerability to schizophrenia. Our aim was to further explore this memory pattern in non-clinical schizotypy in order to determine which specific dimensions of schizotypy (i.e., positive, negative or disorganised), and more specifically which components of the dimensions, are most closely related to memory dysfunctions. METHODS: Fifty-seven undergraduate students performed a category-production task. This was adapted for use with the process dissociation procedure in order to dissociate between automatic and controlled memory processes. The level of schizotypy was assessed using the Schizotypal Personality Questionnaire. RESULTS: Regression analyses confirmed that controlled memory processes decreased as schizotypy increased. The positive factors (more specifically, the ideas of reference subscale) and disorganised factors (more specifically, the odd or eccentric behaviour subscale) were negatively correlated with the controlled memory processes. CONCLUSIONS: Our study supports the idea that impaired controlled processes are an early cognitive marker of vulnerability to schizophrenia and confirm that the disorganised factor contributes the most to vulnerability to memory dysfunction. It also emphasises the importance of dissociating between each of the features characterising schizotypy rather than considering it as a whole.

Behavioral and brain measures (N400) of semantic priming in patients with schizophrenia: test-retest effect in a longitudinal study.

AIM: The purpose of this study was to investigate whether deficits in the behavioral and/or N400 semantic priming (SP) effect observed in patients with schizophrenia constitute a stable cognitive feature of the disorder or whether they may be influenced by the severity of each individual's symptomatology. METHODS: A 1-year test-retest study was conducted on 15 patients with schizophrenia and 10 healthy participants who performed an SP task. Both behavioral measures and event-related potentials measures of SP were recorded twice (test and retest sessions). RESULTS: At test, patients exhibited a deficit in SP as was revealed by both the behavioral and the event-related potentials measures of the amplitude of the N400 component. At retest, behavioral SP remained impaired, whereas N400 SP was significantly improved. CONCLUSION: These results provide evidence that SP impairments in schizophrenia as measured by N400 should not be considered as stable cognitive markers of the disorder. The behavioral and the N400 measures of SP indicated different levels of sensitivity to subtle cognitive and brain processes, which are subject to change over the clinical course of schizophrenic disorder.

Evaluation of an Autism Training in a Much-Needed Context: The Case of France.

Background: Autistic people in France have called for community education to reduce autism stigma. As such, training is needed to help university students appreciate autistic peers and autistic people they may work with in their future careers. Methods: We adapted an autistic-affirming training from a training developed in other cultural contexts and evaluated it with 107 university students in France using a pretest-post-test design. Results: Questionnaire responses suggested that our brief online training helped improve attitudes toward inclusion, autism knowledge, and stigma among future educators and psychologists in France. Participants' open-ended definitions of autism revealed increased alignment with the neurodiversity movement after training. Conclusions: Findings suggest that wider-scale autistic-led adaptations of autism trainings like the one described in this report could begin to ameliorate autism stigma in France.

Why is this an important issue?: Autistic people in France have been treated very badly in the past. They have been left out of school and hurt by professionals. They still face stigma. This means they are often misunderstood, made fun of, and excluded. Some are forced to take medications they do not want. Autistic people in France have been trying to help other people in France understand autism. What was the purpose of this study?: We wanted to see whether autism training could help university students in France to better understand autistic people. We wanted to see whether our training could help students appreciate autistic people more (or lower stigma). We also wanted to see whether the training could help students understand that it is important to include autistic people in classes with other students at school. What did the researchers do?: Researchers in France, Lebanon, and the United States modified an autism training that had been used in other countries. The training was autistic affirming, which means it taught people to listen to autistic people and to see their strengths. We translated it into French. We included training topics that French collaborators thought were important. We asked university students in France who were studying education and psychology to do our training online. We also asked them to fill out surveys about autism. What were the results of the study?: After doing our training, students knew more about autism than they did before training. Some learned that autism is part of a person for their whole life. They seemed to appreciate autistic people more after training. They also agreed that it is important to include autistic people in school with other students more than they had before. What do these findings add to what was already known?: This study shows that autistic-affirming training can also help people in France appreciate autistic people. Much autism training only focuses on stigma and knowledge. Our training may also have helped future educators and clinicians understand how important it is to include autistic people in school with other students. What are potential weaknesses in the study?: The students in our study were mostly women. They were all training for jobs where they can help people. We do not know whether our training would help other French people. We also cannot be sure that our training really helped the students who did it. Students may have been dishonest about how they felt about autism. In future studies, people should see whether training changes what people do, not just what they say. How will these findings help autistic adults now or in the future?: By teaching students in France about autism, we hope to begin to help make life better for autistic people in France. We hope studies like this will help people to understand autistic people better. We also hope more people conduct trainings like that used in this study around the world to improve understanding and treatment of autistic people.

Validation of a short French version of the UPPS-P Impulsive Behavior Scale.

BACKGROUND: Impulsivity is a multifaceted construct that has a prominent role in psychiatry. Lynam et al (2006) have developed the UPPS-P, a 59-item scale measuring 5 impulsivity components: negative urgency, positive urgency, lack of premeditation, lack of perseverance, and sensation seeking. The aim of the present study was to validate a short, 20-item French version of the UPPS-P. METHODS: Six hundred fifty participants filled out the short French UPPS-P. A subgroup of participants (n = 145) took part in a follow-up study and completed the scale twice to determine test-retest stability; another subgroup (n = 105) was screened with other questionnaires also to establish external validity. RESULTS: Confirmatory factor analyses supported a hierarchical model comprising 2 higher order factors of urgency (resulting from negative urgency and positive urgency) and lack of conscientiousness (resulting from lack of premeditation and lack of perseverance) as well as a separate factor of sensation seeking. The results indicated good internal consistency and test-retest stability. External validity was supported by relationships with psychopathological symptoms. CONCLUSION: The short French version of the UPPS-P therefore presents good psychometric properties and may be considered a promising instrument for both research and clinical practice.

Influence of Psychological Vulnerability Factors for Bipolar Disorders on a Semantic Mediated Priming Task.

Hypomanic personality, hyperthymic temperament and irritable temperament are considered as psychological vulnerability factors to bipolar disorders. Semantic memory is impaired in bipolar patients. Spreading activation is among the probable candidates for accounting this impairment. The aim of this study was to assess spreading activation according to vulnerability factors continuum to determine whether it could be a factor of vulnerability to bipolar disorders. A sample of 61 healthy volunteers was recruited. Spreading activation was assessed by semantic mediated priming implemented in a double lexical decision task. Results shown that semantic mediated priming was negatively associated to hyperthymic temperament and irritable temperament. Impairment in semantic memory, and more specifically spreading activation, appear to be a cognitive factor of vulnerability to bipolar disorders. Our results can contribute to a better understanding of semantic impairment in vulnerable population and in bipolar disorder.

Neural correlates of semantic ambiguity resolution in paucisymptomatic bipolar disorder patients.

In addition to symptoms specifically related to mood dysregulation, patients with bipolar disorder (BD) show frequent alterations in formal thought organization. A disruption in semantic processing, notably in semantic inhibition, is one of the possible mechanisms that might explain this modified organization. However, to date, little is known about these mechanisms and their underlying neural substrates. This study aimed to identify the neural correlates of the semantic inhibition process in BD patients in comparison to healthy controls. Seventeen BD patients and 17 matched controls were recruited and underwent a 3T MRI scan. A semantic ambiguity resolution task was used during the scan to explore semantic inhibition. Whole-brain analyses were conducted on 13 BD patients and 16 controls. When compared to controls, BD patients had stronger activation in the bilateral temporal areas and right middle frontal gyrus, and less activation in the right hippocampus, parahippocampal area, and bilateral precunei. The present study revealed an altered fronto-temporo-parietal semantic inhibition network in BD patients that could reflect compensative mechanisms or modified semantic processing inducing abnormal thought organization, which has a major impact on the occupational and social functioning of the BD population.

Disentangling the role of social cognition processes at early steps of alcohol abuse: The influence of affective theory of mind.

Excessive alcohol use among adolescents has become a pressing challenge among Western societies. Accordingly, one of the current research objectives is to identify the processes associated with this harmful habit. Although numerous studies have underlined the role of executive and motivational processes, few have explored emotional and interpersonal abilities at early steps of alcohol abuse. The present study evaluated the role of two social cognition processes, namely theory of mind (ability to infer others' mental states at cognitive and affective levels) and empathy (ability to understand others' feelings at cognitive and affective levels) in adolescents' alcohol consumption. Two hundred and two adolescents (13-20 years old) performed a behavioral task evaluating theory of mind and filled in questionnaires measuring personal data, empathy, alcohol consumption (alcohol abuse and specific binge drinking), as well as depressive and anxiety symptoms. Findings showed that cognitive and affective empathy were negatively associated with alcohol consumption in youth whereas affective theory of mind was related to specific binge drinking. Importantly, affective theory of mind predicted binge drinking in adolescents, even after controlling for age, gender, and education level. These results emphasized the role of social cognition in early alcohol abuse and showed that, beyond inhibition, interpersonal abilities might precipitate excessive drinking in youth.

Brief aerobic exercise immediately enhances visual attentional control and perceptual speed. Testing the mediating role of feelings of energy.

While the effects of acute exercise on mood and cognitive functions have been separately documented over the last decade, recent findings have pointed to a possible connection between affective responses to exercise and cognitive performance. The main objective of this study was to test whether the effects of acute exercise on cognition were mediated by changes in feelings of energy. One-hundred-and-one undergraduate students were randomized into one of two experimental conditions: 15 min of jogging at "moderate" intensity, or 15 min of relaxation/concentration (control condition). Perceptual speed, visual attentional control, working memory, and cognitive flexibility were assessed pre- and post-intervention in both groups via the Trail Making Test. Self-rated feelings of energy were also recorded pre- and post-intervention. Only completion time for the TMT-A significantly improved from pre- to post-intervention in participants who exercised compared with participants who practiced relaxation/concentration. No Group × Time interaction was found with regard to the other TMT variables. Finally, changes in feelings of energy were found to fully mediate the relationship between exercise and perceptual speed/visual attentional control. Taken together, our data suggest that a brief bout of moderate intensity exercise can improve the efficiency of certain cognitive processes through increases in feelings of energy, but further research is required to evaluate the duration of benefits and to determine whether these apply to other populations.

Neural Correlates of Semantic Inhibition in Relation to Hypomanic Traits: An fMRI Study.

OBJECTIVES: Language modifications are a core feature of mania, but little is known about the semantic mechanisms behind these disturbances. The aim of the present study was thus to identify deficits in semantic inhibition and their respective neural activation patterns in a sample of individuals assessed for hypomanic personality traits. METHODS: Thirty-six young adults with no neurological or psychiatric diagnoses were assessed for hypomanic personality traits with the Hypomanic Personality Scale (HPS) and underwent an fMRI task of semantic ambiguity resolution. RESULTS: Regression analyses revealed a positive association between the HPS score and activity in the left superior frontal gyrus, left inferior parietal lobule, and anterior cingulate gyrus during semantic ambiguity resolution. CONCLUSION: We found a link between HPS scores and brain areas that are part of the cognitive control loop and semantic memory network during language processing in a nonclinical sample of individuals. The hyperactivation of these regions may reflect a compensatory neural response in a population with greater vulnerability to BD.

Verbal fluency in bipolar disorders: A systematic review and meta-analysis.

BACKGROUND: One of the main features of bipolar disorder (BD), besides mood dysregulation, is an alteration of the structure of language. Bipolar patients present changes in semantic contents, impaired verbal associations, abnormal prosody and abnormal speed of language highlighted with various experimental tasks. Verbal fluency tasks are widely used to assess the abilities of bipolar patients to retrieve and produce verbal material from the lexico-semantic memory. Studies using these tasks have however yielded discrepant results. The aim of this study was thus to determine the extent of the verbal fluency impairment in BD patients and to evaluate if the deficits are affected by the type of task or by mood states. METHODS: A systematic literature search was conducted in MEDLINE, EBSCOHost and Google Scholar and relevant data were submitted to a meta-analysis. RESULTS: Thirty-nine studies were retained providing data for 52 independent groups of BD patients. The overall meta-analysis revealed a moderate verbal fluency impairment in BD compared to healthy controls (effect size d=0.61). Comparisons between mood states showed significant differences only between euthymic and manic patients and only on category fluency performances. LIMITATIONS: This review is limited by the heterogeneity between studies for the characteristics of BD populations. Also, few of the retained studies examined depressive or mixed episodes. CONCLUSIONS: This work confirms that BD patients present with moderate verbal fluency impairments, and underlines the specific effect of mood state on category fluency. This emphasizes the need to distinguish semantic from phonological processes in verbal fluency assessments in BD.

Double-decision lexical tasks in thought-disordered schizophrenic patients: a path towards cognitive remediation?

It has been shown that schizophrenics have certain difficulties in the processing of semantic context. These difficulties have usually been evaluated using lexical decision tasks with semantic priming. In this study, we chose to examine the idea of an abnormality in the early stages of semantic context processing in thought-disordered schizophrenics using two double lexical decision tasks: one with a high (25%) and one with a low (15%) proportion of related words to assess the participants' competency in controlled and possibly also more automatic context processing. The results obtained in 40 control participants and 40 schizophrenic patients revealed no significant differences in the amplitude of semantic priming between the two groups. These results suggest that, in the disorganized schizophrenic subjects evaluated in this study, the context processing processes mobilized by the employed tasks were unimpaired.

Emotional Meaning in Context in Relation to Hypomanic Personality Traits: An ERP Study.

The ability to integrate contextual information is important for the comprehension of emotional and social situations. While some studies have shown that emotional processes and social cognition are impaired in people with hypomanic personality trait, no results have been reported concerning the neurophysiological processes mediating the processing of emotional information during the integration of contextual social information in this population. We therefore chose to conduct an ERP study dealing with the integration of emotional information in a population with hypomanic personality trait. Healthy participants were evaluated using the Hypomanic Personality Scale (HPS), and ERPs were recorded during a linguistic task in which participants silently read sentence pairs describing short social situations. The first sentence implicitly conveyed the positive or negative emotional state of a character. The second sentence was emotionally congruent or incongruent with the first sentence. We analyzed the difference in the modulation of two components (N400 and LPC) in response to the emotional word present at the end of the "target" sentences as a function of the HPS score and the emotional valence of the context. Our results showed a possible modulation of the N400 component in response to both positive and negative context among the participants who scored high on the Mood Volatility subscale of the Hypomanic Personality Scale. These results seem to indicate that the participants with hypomanic personality traits exhibited specificities in the integration of emotions at the level of the early-mobilized neurocognitive processes (N400). Participants with hypomanic personality traits found it difficult to integrate negative emotional contexts, while simultaneously exhibiting an enhanced integration of positive emotional contexts.

Theory of mind and hypomanic traits in general population.

Theory of Mind (ToM) is the ability to assign a set of mental states to yourself and others. In bipolar disorders, alteration of social relationship can be explained by the impairment of the functioning of ToM. Deficit in ToM could be a trait marker of bipolar disorder and people in the general population with high hypomanic personality scores would be more likely to develop bipolar disorders. This study examined 298 participants. Measures of hypomanic personality were evaluated using the Hypomanic Personality Scale. ToM was explored using the Yoni task. Participants also completed the BDI-II. Forward multiple regressions were performed to examine the effect of components of the HPS on the total score in the ToM task. In the women's group, no subscales of the HPS were included in the model. Conversely, the analyses performed on men revealed that the mood vitality and excitement subscale was a significant predictor of ToM abilities. Our study is the first to show the impact of certain dimensions of hypomanic personality on performance in ToM in a male sample. This result supports the idea that deficits in ToM can be a trait marker of bipolar disorder in a healthy male population.
