Protocol for the MS-CEBA study: an observational, prospective cohort study identifying Cognitive, Energetic, Behavioural and Affective (CEBA) profiles in Multiple Sclerosis to guide neuropsychological treatment choice

BACKGROUND

Neuropsychological symptoms in the Cognitive, Energetic, Behavioural, and Affective (CEBA) domains are common in people with multiple sclerosis (PwMS) and can negatively affect societal participation. The current study aims to investigate whether there are combinations of symptoms in the different CEBA domains that consistently occur together, that is, if there are CEBA profiles that can be identified. If so, this study aims to develop a screening instrument identifying CEBA profiles in PwMS to select the most suitable neuropsychological rehabilitation treatment for a given CEBA profile and consequently improve the societal participation of PwMS.

METHODS

This study is an observational, prospective cohort study consisting of 3 phases. Phase 1 focuses on the identification of CEBA profiles in a large sample of PwMS (n = 300). Phase 2 focuses on validating these CEBA profiles through replication of results in a new sample (n = 100) and on the development of the screening instrument. Phase 3 focuses on qualitatively evaluating in a small group of PwMS whether the selected treatment is suitable for the given CEBA profile or whether existing neuropsychological treatments should be adapted to meet the needs of PwMS suffering from symptoms in multiple CEBA domains simultaneously. Primary outcome is the CEBA profile, which will be derived from performance on neuropsychological assessment consisting of tests and questionnaires regarding the CEBA domains using a latent profile analysis. Inclusion criteria include MS diagnosis, sufficient ability in the Dutch language, and an age between 18 and 70 years.

DISCUSSION

The results of the current study will contribute to a more comprehensive understanding of the entire spectrum of neuropsychological symptoms in PwMS. Identification of possible CEBA profiles, and accordingly, the development of a screening instrument determining the CEBA profile of PwMS in clinical practice, contributes to the timely referral of PwMS to the most suitable neuropsychological rehabilitation treatment. If necessary, adjustments to existing treatments will be suggested in order to sufficiently meet the needs of PwMS. All of this with the ultimate aim to improve societal participation, and thereby quality of life, of PwMS.

A Systematic Review and Meta-Analysis of Social Cognition Among People Living with HIV: Implications for Non-Social Cognition and Social Everyday Functioning

Social cognition-the complex mental ability to perceive social stimuli and negotiate the social environment-has emerged as an important cognitive ability needed for social functioning, everyday functioning, and quality of life. Deficits in social cognition have been well documented in those with severe mental illness including schizophrenia and depression, those along the autism spectrum, and those with other brain disorders where such deficits profoundly impact everyday life. Moreover, subtle deficits in social cognition have been observed in other clinical populations, especially those that may have compromised non-social cognition (i.e., fluid intelligence such as memory). Among people living with HIV (PLHIV), 44% experience cognitive impairment; likewise, social cognitive deficits in theory of mind, prosody, empathy, and emotional face recognition/perception are gradually being recognized. This systematic review and meta-analysis aim to summarize the current knowledge of social cognitive ability among PLHIV, identified by 14 studies focused on social cognition among PLHIV, and provides an objective consensus of the findings. In general, the literature suggests that PLHIV may be at-risk of developing subtle social cognitive deficits that may impact their everyday social functioning and quality of life. The causes of such social cognitive deficits remain unclear, but perhaps develop due to (1) HIV-related sequelae that are damaging the same neurological systems in which social cognition and non-social cognition are processed; (2) stress related to coping with HIV disease itself that overwhelms one's social cognitive resources; or (3) may have been present pre-morbidly, possibly contributing to an HIV infection. From this, a theoretical framework is proposed highlighting the relationships between social cognition, non-social cognition, and social everyday functioning.

Creating A child-friendly social environment for fewer conduct problems and more prosocial behaviors among children: A LASSO regression approach

BACKGROUND

Creating a child-friendly social environment is an important component of promoting child-friendly city development. This study aims to explore the key indicators of friendly family, school and community social environments from the perspective of children's conduct problems and prosocial behaviors.

METHOD

The sample included grade 3-5 students from one public elementary school in the urban areas and another public elementary school in the rural areas of a Chinese city pursuing a child-friendly philosophy. A total of 418 participants were included in this study. Data on conduct problems, prosocial behaviors and the social environment were collected. To effectively select important variables and eliminate estimation bias, this study used LASSO regression to identify key indicators predicting children's conduct problems and prosocial behavior, followed by linear regression coefficient estimation and significance testing.

RESULTS

Creating a friendly family environment (ensuring family members' assistance with academic problems) and school environment (reducing cheating, fighting, and unfriendly teacher language) was associated with reduced conduct problems in children. Creating a positive family atmosphere (enhancing children's trust in family members), school environment (increasing parents' awareness of school affairs, reinforcing students' prosocial behavior, increasing extracurricular activity programs, and encouraging student engagement in academics) and community environment (respecting all children in the community) was associated with improving children's prosocial behavior.

CONCLUSIONS

This study transforms the multidimensional, complex child-friendly social environment evaluation indicator system into concise and specific measurement indicators, which can provide theoretical and practical implications for government decision-making in child-friendly city development through empirical research.

Measuring mindreading in preschoolers: The perspective battery (PERBAT)

OBJECTIVE

The capacity to take another person's visual perspective is pivotal for solving mindreading tests, such as Theory of Mind (ToM) tasks, but most of them heavily rely on domain-general abilities (e.g., language, executive functions). Here we present a novel battery of visual perspective-taking tests for child neuropsychological assessment, the Perspective Battery (PERBAT), which poses a limited load on domain-general abilities.

METHODS

The battery includes four tests: i) Block Building; ii) Hide and Seek; iii) Deceptive Figures; iv) Double-Sided Shelf. We administered the PERBAT to 126 typically developing preschoolers (65 males; 3-6-year-old); the participants also performed classical tests of social cognition, language, and nonverbal abstract reasoning.

RESULTS

The scores of all the PERBAT tests were significantly and positively related with age and scores of the classical social cognition tests, but not with scores of the language and nonverbal abstract reasoning tests.

CONCLUSIONS

The PERBAT could represent a useful neuropsychological tool providing a comprehensive assessment of visual perspective-taking skills in preschool children. Future investigation is needed to examine the validity of the PERBAT with neurotypical samples across countries, race, ethnicity, and language as well as with clinical populations. Longitudinal studies are also encouraged to examine whether early visual perspective-taking weaknesses are associated with later development of mindreading skills.

Mouse auditory cortex sub-fields receive neuronal projections from MGB subdivisions independently

Mouse auditory cortex is composed of six sub-fields: primary auditory field (AI), secondary auditory field (AII), anterior auditory field (AAF), insular auditory field (IAF), ultrasonic field (UF) and dorsoposterior field (DP). Previous studies have examined thalamo-cortical connections in the mice auditory system and learned that AI, AAF, and IAF receive inputs from the ventral division of the medial geniculate body (MGB). However, the functional and thalamo-cortical connections between nonprimary auditory cortex (AII, UF, and DP) is unclear. In this study, we examined the locations of neurons projecting to these three cortical sub-fields in the MGB, and addressed the question whether these cortical sub-fields receive inputs from different subsets of MGB neurons or common. To examine the distributions of projecting neurons in the MGB, retrograde tracers were injected into the AII, UF, DP, after identifying these areas by the method of Optical Imaging. Our results indicated that neuron cells which in ventral part of dorsal MGB (MGd) and that of ventral MGB (MGv) projecting to UF and AII with less overlap. And DP only received neuron projecting from MGd. Interestingly, these three cortical areas received input from distinct part of MGd and MGv in an independent manner. Based on our foundings these three auditory cortical sub-fields in mice may independently process auditory information.

Theory of mind in chronic migraine with medication overuse assessed with the MASC

Theory of Mind (ToM) is the ability to infer one's own and others' mental states. Growing research indicates that ToM is impaired in Chronic Migraine with Medication Overuse (CM + MO). However, the research in this field has been conducted using static scenario-based tasks, often failing to test mentalization in everyday situations and measuring only performance accuracy. We filled this gap by administering the Movie for the Assessment of Social Cognition (MASC) to subjects with CM + MO compared to episodic migraine (EM). This test allows us to assess both affective and cognitive ToM and which, in addition to being accurate, also analyzes the type of error in attribution of mental states, distinguishing between hypo-mentalization and hyper-mentalization. Thirty patients suffering from CM + MO and 42 from EM were enrolled. Results showed that CM + MO patients were less accurate in mental state attribution than EM. In addition, compared to EM, CM + MO individuals were more impaired in the affective ToM dimensions and committed more errors of hypo-mentalization. In conclusion, the application of MASC in patients with CM + MO allowed for the detection of an alteration in their ability to correctly draw conclusions about other people's mental states. This latter contributes critically to appropriate social reactions and also, possibly, to satisfactory social interactions.

The neural basis of naturalistic semantic and social cognition

Decoding social environments and engaging meaningfully with other people are critical aspects of human cognition. Multiple cognitive systems, including social and semantic cognition, work alongside each other to support these processes. This study investigated shared processing between social and semantic systems using neuroimaging data collected during movie-viewing, which captures the multimodal environment in which social knowledge is exchanged. Semantic and social content from movie events (event-level) and movie transcripts (word-level) were used in parametric modulation analyses to test (1) the degree to which semantic and social information is processed within each respective network and (2) engagement of the same cross-network regions or the same domain-general hub located within the semantic network during semantic and social processing. Semantic word and event-level content engaged the same fronto-temporo-parietal network and a portion of the semantic hub in the anterior temporal lobe (ATL). Social word and event-level content engaged the supplementary motor area and right angular gyrus within the social network, but only social words engaged the domain-general semantic hub in left ATL. There was evidence of shared processing between the social and semantic systems in the dorsolateral portion of right ATL which was engaged by word and event-level semantic and social content. Overlap between the semantic and social word and event results was highly variable within and across participants, with the most consistent loci of overlap occurring in left inferior frontal, bilateral precentral and supramarginal gyri for social and semantic words and in bilateral superior temporal gyrus extending from ATL posteriorly into supramarginal gyri for social and semantic events. These results indicate a complex pattern of shared and distinct regions for social and semantic cognition during naturalistic processing.

Normative values and diagnostic optimisation of three social cognition measures for autism and schizophrenia diagnosis in a healthy adolescent and adult sample

Awareness of the importance of assessing social cognition skills under conditions showing atypical social behaviours has increased over the years. However, the evaluation of the psychometric properties of the measures and the availability of normative values for the clinical context are still limited. This study aims to revise, provide normative values, and evaluate the clinical validity of the Italian version of three social cognition measures: Advanced Theory of Mind (A-ToM) task, the Emotion Attribution Task (EAT), and the Social Situation Task (SST). Measures were administered to 580 adolescents and adult healthy controls (age range 14-50). We performed differential item functioning and Rasch analysis to revise each task, so normative data of the revised measures were calculated. Moreover, the revised measures were administered to 38 individuals with autism spectrum disorder (ASD) and 35 individuals with schizophrenia spectrum disorders (SSD): ASD and SSD were matched by age, gender, and IQ with a control sample to evaluate clinical validity. ROC analysis showed that the SST is the best measure differentiating between healthy and clinical groups, compared to the A-ToM (AUCASD = 0.70; AUCSSD = 0.65) and EAT (AUCASD = 0.67; AUCSSD = 0.50), which showed poorer performance. For SSD diagnosis, two SST subscales (Violation and Gravity score) indicated the best accuracy (AUCs of 0.88 and 0.84, respectively); for the ASD diagnosis, we propose a combined score between the SST subscale and A-ToM (AUC = 0.86). The results suggest that the proposed measures can be used to support the diagnostic process and clinical practice.

Diminished hedonic capacity in social activities as a mediator of the link between dysfunctional behavioral activation system and depressive symptoms

Background

Adolescence is a crucial period for the development of depression, and previous studies have suggested that the Behavioral Activation System (BAS) plays a significant role. However, little is known about the underlying mechanisms. This study aimed to explore the mediating role of anhedonia in the relationship between BAS and depressive symptoms among Chinese adolescents.

Method

A total of 1,023 high-school students aged 15-18 years participated in the study, with 916 continuing their participation three months later. All participants completed the Behavioral Inhibition System/Activation System (BIS/BAS) scale, Dimensional Anhedonia Rating Scale (DARS), Children's Depression Inventory (CDI), and the State-Trait Anxiety Inventory (STAI-S/T). Pathway model analysis was performed to examine the concurrent and prospective mediating effects of anhedonia and the potential moderating effect of sex.

Result

Anhedonia in the domains of social activities, hobbies and sensory experiences significantly mediated the cross-sectional relationship between BAS and depressive level three months later. Furthermore, the beta-value of the mediating effect of social activities was significantly higher than that of the other domains of hedonic capacity cross-sectionally and longitudinally. However, sex showed no significant moderating effect.

Conclusion

Our findings underscore the importance of hedonic capacity, especially within the social domain, in the development of depressive symptoms. These findings contribute to the early diagnosis and prevention of depressive disorders.

Difficulties in social cognitive functioning among pediatric patients with muscular dystrophies

Introduction

Pediatric muscular dystrophies (MDs) are a heterogeneous group of rare neuromuscular diseases characterized by progressive muscle degeneration. A neuropsychosocial approach is crucial for these patients due to associated cognitive, behavioral, and psychiatric comorbidities; however, the social cognitive domain has not been adequately addressed.

Methods

This study aimed to analyze on social cognition performance in a pediatric MD patient cohort. This cross-sectional study included 32 pediatric patients with MD and 32 matched-healthy controls. The Social Perception Domain of the NEPSY-II, the Reading the Mind in the Eyes Test-Child and Happé's Strange Stories Test were administered. General intelligence and behavioral and emotional symptoms were controlled for to eliminate covariables' possible influence. The assessments were performed remotely.

Results

Children with MDs performed significantly worse on most of the social cognition tasks. The differences found between the groups could be explained by the level of general intelligence for some aspects more related to theory of mind (ToM) (TM NEPSY-II: F = 1.703, p = .197; Verbal task: F = 2.411, p = .125; RMET-C: F = 2.899, p = .094), but not for emotion recognition. Furthermore, these differences were also independent of behavioral and emotional symptoms.

Discussion

In conclusion, social cognition is apparently impaired in pediatric patients with MD, both for emotion recognition and ToM. Screening assessment in social cognition should be considered to promote early interventions aimed at improving these patient's quality of life.

Association of Radiation Dose to the Amygdala-Orbitofrontal Network with Emotion Recognition Task Performance in Patients with Low-Grade and Benign Brain Tumors

BACKGROUND

Although data are limited, difficulty in social cognition occurs in up to 83% of patients with brain tumors. It is unknown whether cranial radiation therapy (RT) dose to the amygdala-orbitofrontal network can impact social cognition.

METHODS

We prospectively enrolled 51 patients with low-grade and benign brain tumors planned for cranial RT. We assessed longitudinal changes on an emotion recognition task (ERT) that measures the ability to recognize emotional states by displaying faces expressing six basic emotions and their association with the RT dose to the amygdala-orbitofrontal network. ERT outcomes included the median time to choose a response (ERTOMDRT) or correct response (ERTOMDCRT) and total correct responses (ERTHH).

RESULTS

The RT dose to the amygdala-orbitofrontal network was significantly associated with longer median response times on the ERT. Increases in median response times occurred at lower doses than decreases in total correct responses. The medial orbitofrontal cortex was the most important variable on regression trees predicting change in the ERTOMDCRT.

DISCUSSION

This is, to our knowledge, the first study to show that off-target RT dose to the amygdala-orbitofrontal network is associated with performance on a social cognition task, a facet of cognition that has previously not been mechanistically studied after cranial RT.

Seeing emotions in the eyes: a validated test to study individual differences in the perception of basic emotions

People are able to perceive emotions in the eyes of others and can therefore see emotions when individuals wear face masks. Research has been hampered by the lack of a good test to measure basic emotions in the eyes. In two studies respectively with 358 and 200 participants, we developed a test to see anger, disgust, fear, happiness, sadness and surprise in images of eyes. Each emotion is measured with 8 stimuli (4 male actors and 4 female actors), matched in terms of difficulty and item discrimination. Participants reliably differed in their performance on the Seeing Emotions in the Eyes test (SEE-48). The test correlated well not only with Reading the Mind in the Eyes Test (RMET) but also with the Situational Test of Emotion Understanding (STEU), indicating that the SEE-48 not only measures low-level perceptual skills but also broader skills of emotion perception and emotional intelligence. The test is freely available for research and clinical purposes.

Altered social cognition in early relapsing remitting multiple sclerosis

INTRODUCTION

People with multiple sclerosis (pwMS) may suffer from some degree of impaired social cognition (SC), the process that integrates the mental operations underlying social interactions. SC is still not clearly characterized in the early stages of MS, and it is not defined whether SC is independent of cognitive impairment.

METHODS

In this cross-sectional study, we aimed to compare SC measures in a population of early (≤5 years) relapsing-remitting MS (RRMS) with an age, sex, and education-matched control group. All participants performed a clinical and a comprehensive neuropsychological assessment. SC evaluation included assessment of facial emotion recognitionn by the Emotion Recognition Task, affective theory of mind (ToM) by the Reading the Mind in the eyes Test (RMET) and cognitive ToM by the Faux Pas test (FPT). Depression, anxiety, fatigue, and quality of life were also assessed. We included 38 pwMS (mean age 34.8 ± 8.7, 78.9% female sex, mean disease duration 1.9±1.3 years) and 38 healthy controls (mean age 34.9 ± 8.4, 81.6% female sex).

RESULTS

Altered social cognition was present in 34.2% of pwMS. Participants with MS performed worse than controls on measures of cognitive ToM, and affective ToM. There were no differences regarding FER. Cognitive ToM and FER correlated with cognitive functions, but no correlation was found between affective ToM and cognitive tests. The only clinical factor associated with altered SC was poor quality of life.

CONCLUSIONS

Social cognition impairment is already present in a significant percentage of early RRMS patients, namely ToM deficits. While cognitive ToM and FER appears to correlate with impaired cognitive results, affective ToM is likely independent of other cognitive functions.

What Is the True Impact of Cognitive Impairment for People Living with Multiple Sclerosis? A Commentary of Symposium Discussions at the 2020 European Charcot Foundation

Multiple sclerosis (MS) is a chronic, neurodegenerative, inflammatory condition usually associated with physical disability. Clinical care has been skewed toward the physical manifestations of the disease, yet a range of silent symptoms occurs including the cognitive aspects of MS. In a 2018 meeting of MS in the 21st Century (MS21), an international steering committee comprising both specialists and patient experts recognised that the 'invisible symptoms' of MS pose a significant challenge to patient engagement. These findings prompted the European Charcot Foundation (ECF) MS21 symposium (2020), where a panel consisting of two leading MS clinicians and an MS patient expert (who were all members of the MS21 steering group) gathered to discuss the impact of cognitive impairment on the everyday lives of people with MS.The perspectives and experiences of the panellists are summarised in this paper. The key points raised were that (1) the cognitive manifestations of MS are under-recognised and have consequently been undermanaged from a clinical perspective and (2) cognitive impairment due to MS has a significant impact upon daily living and patient quality of life. During discussions about how these challenges can be addressed, the panel advocated for an improvement in education about cognitive symptoms for people living with MS and healthcare professionals (HCPs) to raise awareness about this aspect of MS. Furthermore, the panel emphasised the importance of open and proactive communication between HCPs and their patients with MS about cognitive symptoms to reduce the stigma attached to these symptoms. In the opinion of the panel, future clinical trials which include cognitive outcomes as key endpoints are needed. Reflecting this point, cognitive impairment in MS care also needs to be treated as an important disease symptom, as is done with physical symptoms of the disease. Implementing early and routine cognition screening and promoting measures for protecting cognition to people living with MS, such as cognitive rehabilitation and a 'brain-healthy' lifestyle, are actions which can drive forward the recognition of cognitive impairment as a care priority.If prioritised as highly as physical disability in both the MS care and clinical drug development setting, and proactively discussed in conversations between HCPs and patients with MS, the 'invisibility' of cognitive impairment in MS can be lifted and a better quality of life can be promoted for people living with MS.

Introducing a Real-Time Method for Identifying the Predictors of Noncompliance with Event-Based Reporting of Tobacco Use in Ecological Momentary Assessment

BACKGROUND

Little is known about the factors that bias event-based (i.e., self-initiated) reporting of health behaviors in ecological momentary assessment (EMA) due to the difficulty inherent to tracking failures to self-initiate reports.

PURPOSE

To introduce a real-time method for identifying the predictors of noncompliance with event-based reporting.

METHODS

N = 410 adults who used both cigarettes and e-cigarettes completed a 1-week EMA protocol that combined random reporting of current contexts with event-based reporting of tobacco use. Each random assessment first asked if participants were currently using tobacco and, if so, the assessment converted into a "randomly captured" event report-indicating failure to self-initiate that report. Multilevel modeling tested predictors of failing to complete random reports and failing to self-initiate event reports.

RESULTS

On the person level, male sex, higher average cigarette rate, and higher average cigarette urge each predicted missing random reports. The person-level predictors of failing to self-initiate event reports were older age, higher average cigarette and e-cigarette rates, higher average cigarette urge, and being alone more on average; the moment-level predictors were lower cigarette urge, lower positive affect, alcohol use, and cannabis use. Strikingly, the randomly captured events comprised more of the total EMA reports (28%) than did the self-initiated event reports (24%). These report types were similar across most variables, with some exceptions, such as momentary cannabis use predicting the random capture of tobacco events.

CONCLUSIONS

This study demonstrated a method of identifying predictors of noncompliance with event-based reporting of tobacco use and enhancing the real-time capture of events.

Effect of physical exercise on social adaptability of college students: Chain intermediary effect of social-emotional competency and self-esteem

Objective

To explore the relationship between physical exercise and college students' social adaptability, as well as the mediating role of social-emotional competency and self-esteem.

Methods

One thousand two hundred thirty college students were investigated by physical exercise questionnaire, social-emotional competency scale, self-esteem scale, and social adaptability scale. Data were analyzed by Pearson correlation analysis, structural equation model test and deviation-corrected percentile Bootstrap method.

Results

(1) Physical exercise was positively correlated with social adaptability (r = 0.397, p < 0.01), and the direct path of physical exercise on social adaptability was significant (β = 0.397, t = 15.174, p < 0.01). (2) Physical exercise positively predicted social-emotional competency (β = 0.399, t = 15.235, p < 0.01) and self-esteem (β = 0.305, t = 10.570, p < 0.01). Social-emotional competency positively predicted self-esteem (β = 0.130, t = 4.507, p < 0.01) and social adaptability (β = 0.169, t = 6.104, p < 0.01). Self-esteem positively predicted social adaptability (β = 0.189, t = 6.957, p < 0.01). (3) Social-emotional competency and self-esteem play a significant mediating role between physical exercise and social adaptability. The mediating effect includes three paths: physical exercise→social-emotional competency→social adaptability (the mediating effect value: 0.068); physical exercise→self-esteem→social adaptability (the mediating effect value: 0.059). Physical exercise→social-emotional competency→self-esteem→social adaptability (the mediating effect value: 0.010).

Conclusion

Physical exercise can not only directly affect social adaptability of college students, but also indirectly affect social adaptability through the independent intermediary role of social-emotional competency and self-esteem. Furthermore, physical exercise also affect social adaptability through the chain mediation of social-emotional competency and self-esteem.

Reflections on extraordinary knowing: Insight into the nature of the mind

Scientists have spent considerable time and effort studying and mapping the geography of the brain, with the expectation that this understanding will lead to insights related to the nature of the mind. This article discusses evidence that, while the mind utilizes sensory information processed by the brain, awareness is not limited to these structures. Research studies give evidence supporting the mind's ability to expand awareness to include perception of objects and events not available to the five senses. This awareness also extends to moments in the future, including the mind's ability to access information seconds or even days in advance of the occurrence. A major brain filter that limits this capacity for expanded awareness is the Default Mode Network (DMN). We summarize research showing that when the DMN activity is reduced, e.g., through meditation, ingestion of neuromodulatory drugs, or NDEs, filtering within the brain is reduced, there is a concomitant development of new connectivity, and these neural changes are correlated with access to expanded awareness.

The Assessment of the Socioemotional Disorder in Neurodegenerative Diseases with the Revised Self-Monitoring Scale (RSMS)

BACKGROUND

Social cognition helps people to understand their own and others' behavior and to modulate the way of thinking and acting in different social situations. Rapid and accurate diagnoses of neurodegenerative diseases are essential, as social cognition is affected by these diseases. The Revised Self-Monitoring Scale (RSMS) is a scale that detects social-emotional cognition deficits.

AIM

The aim of the current study is to examine how socioemotional parameters are affected by neurodegenerative diseases and whether the RSMS can discern these disorders based on the socioemotional parameters in the Greek population.

METHODS/DESIGN

A total of 331 dementia subjects were included. Mini Mental State Examination (MMSE) and Addenbrooke's Cognitive Examination (Revised, ACE-R) measurements were used in order to assess the cognitive deficits. The Neuropsychiatric Inventory (NPI) was used for the evaluation of the neuropsychiatric symptoms. The RSMS and its two subscales was used in order to detect the socioemotional deficits.

RESULTS

The RSMS and its two subscales (RSMS_EX and RSMS_SP) can effectively detect neurodegenerative diseases. The RSMS can detect bvFTD in Alzheimer's Disease (AD), AD in a healthy cohort, behavioral variant Frontotemporal Dementia (bvFTD) in a healthy cohort, bvFTD in Parkinson's Disease (PD) and Frontotemporal Semantic Dementia (FTD/SD) in a healthy cohort. It is a useful tool in order to detect frontotemporal dementias. RSMS correlated negatively with the NPI questionnaire total and the subcategories of apathy, disinhibition and eating disorders. The RSMS results are associated with the ACE-R score (specifically verbal fluency).

CONCLUSIONS

The RSMS is a helpful tool in order to identify socioemotional deficits in neurodegenerative dementias. It is also a useful scale that can discern bvFTD and svPPA in AD patients. A worse RSMS score correlates with a worse ACE-R and NPI. It seems to be a useful scale that can reliably measure social behavior in non-reversible neurodegenerative disorders, such as AD, FTD (bvFTD, svPPA), PDD and PD. The results also apply to the Greek population.

Corpus Callosum Microstructural Tract Integrity Relates to Longer Emotion Recognition Reaction Time in People with Schizophrenia

Objective: Schizophrenia is a complex functionally debilitating neurodevelopmental disorder, with associated social cognitive impairment. Corpus Callosum (CC) white matter tracts deficits are reported for people with schizophrenia; however, few studies focus on interhemispheric processing relative to social cognition tasks. This study aimed to determine if a relationship between the CC and social cognition exists. Method: In this cross-section study, a sample of n = 178 typical controls and n = 58 people with schizophrenia completed measures of mentalising (Reading the Mind in the Eyes), emotion recognition outcome and reaction time (Emotion Recognition Test), and clinical symptoms (Positive and Negative Symptom Scale), alongside diffusion-based tract imaging. The CC and its subregions, i.e., the genu, body, and splenium were the regions of interest (ROI). Results: Reduced white matter tract integrity was observed in the CC for patients when compared to controls. Patients performed slower, and less accurately on emotion recognition tasks, which significantly and negatively correlated to the structural integrity of the CC genu. Tract integrity further significantly and negatively related to clinical symptomatology. Conclusions: People with schizophrenia have altered white matter integrity in the genu of the CC, compared to controls, which relates to cognitive deficits associated with recognising emotional stimuli accurately and quickly, and severity of clinical symptoms.

Children's perspectives on friendships and socialization during the COVID-19 pandemic: A qualitative approach

BACKGROUND

Good quality friendships and relationships are critical to the development of social competence and are associated with quality of life and mental health in childhood and adolescence. Through social distancing and isolation restrictions, the COVID-19 pandemic has had an impact on the way in which youth socialize and communicate with friends, peers, teachers and family on a daily basis. In order to understand children's social functioning during the pandemic, it is essential to gather information on their experiences and perceptions concerning the social changes unique to this period. The objective of this study was to document children and adolescents' perspectives regarding their social life and friendships during the COVID-19 pandemic, through qualitative interviews.

METHODS

Participants (N = 67, 5-14 years) were recruited in May and June 2020. Semi-structured interviews were conducted via a videoconferencing platform. A thematic qualitative analysis was conducted based on the transcribed and coded interviews (NVivo).

RESULTS

The upheavals related to the pandemic provoked reflection among the participants according to three main themes, each of which included sub-themes: (1) the irreplaceable nature of friendship, (2) the unsuspected benefits of school for socialization and (3) the limits and possibilities of virtual socialization.

CONCLUSIONS

The collection of rich, qualitative information on the perspectives of children and adolescents provides a deeper understanding of the consequences of the pandemic on their socialization and psychological health and contributes to our fundamental understanding of social competence in childhood.

Computerized social cognitive training in the subacute phase after traumatic brain injury: A quasi-randomized controlled trial

OBJECTIVES

To assess the usefulness of a computerized tasks module designed for the rehabilitation of social cognition (SC) in acquired brain injury.

METHODS

Quasi-randomized controlled trial (ClinicalTrials.gov:NCT03479970) involving 45 patients with moderate-severe traumatic brain injury (TBI) in a subacute inpatient rehabilitation hospital. The experimental group (n = 28) received treatment with a computerized SC module in combination with a non-SC module. The control group (n = 26) only received a treatment with non-SC module.

RESULTS

Intragroup comparisons showed that the experimental group had better results for all SC measures, except for International Affective Picture System (IAPS). The control group improved for Facial Expressions of cEmotion-Stimuli and Tests (FEEST) and Moving Shapes Paradigm (MSP), showing no changes with respect to pretreatment in IAPS, MSP and Reading the Mind in the Eyes Test (RMET). Intergroup comparisons did not present differences between the two groups for pretreatment measures. Post-treatment comparison showed that the experimental group obtained better results for RMET than the control group.

CONCLUSION

The computerized SC module was useful for the rehabilitation of SC in patients with moderate-severe TBI in the subacute phase. The group that received combined rehabilitative treatment (SC + non-SC) obtained better results for SC than the group that received treatment intended only for non-SC.

Development of an Ecologically Valid Assessment for Social Cognition Based on Real Interaction: Preliminary Results

Many social cognitive assessment measures that are appropriate for clinical use are currently available, but there is a general concern about their ecological validity. This study aimed to develop an applicable real interaction-based test to assess social cognition. A sample of 50 subjects (mean age 22 ± 5.8, 56% women) took the Social Interaction Test as well as two instruments for assessing social cognition: (1) the Movie for Assessment of Social Cognition (MASC) and (2) branch 4 from the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT). The test showed no incidence on its application. The reliability of the 18-item final version of the test was a medium-high level (Cronbach’s alpha = 0.701). To assess the internal structure of the test, a multidimensional scaling procedure was used. The common space of coordinates for the two-dimensional solution showed a normalized raw stress of 0.076 and Tucker’s congruence coefficient of 0.965. The social interaction test showed stronger association with MASC (more realistic, video-based format) than with MSCEIT (less realistic, paper-based format). The Social Interaction Test is applicable and feasible to use it to assess social cognition in the general population.

Assessing and Optimizing Socio-Moral Reasoning Skills: Findings From the MorALERT Serious Video Game

Background

Social cognition and competence are a key part of daily interactions and essential for satisfying relationships and well-being. Pediatric neurological and psychological conditions can affect social cognition and require assessment and remediation of social skills. To adequately approximate the complex and dynamic nature of real-world social interactions, innovative tools are needed. The aim of this study was to document the performance of adolescents on two versions of a serious video game presenting realistic, everyday, socio-moral conflicts, and to explore whether their performance is associated with empathy or sense of presence, factors known to influence social cognition.

Methods

Participants (12–17 years, M = 14.39; SD = 1.35) first completed a pre-test measure of socio-moral reasoning based on three dilemmas from a previously validated computer task. Then, they either played an evaluative version (n = 24) or an adaptive (n = 33) version of a video game presenting nine social situations in which they made socio-moral decisions and provided justifications. In the evaluative version, participants’ audio justifications were recorded verbatim and coded manually to obtain a socio-moral reasoning maturity score. In the adaptive version (AV), tailored feedback and social reinforcements were provided based on participant responses. An automatic coding algorithm developed using artificial intelligence was used to determine socio-moral maturity level in real-time and to provide a basis for the feedback and reinforcements in the game. All participants then completed a three-dilemma post-test assessment.

Results

Those who played the adaptive version showed improved SMR across the pre-test, in-game and post-test moral maturity scores, F(1.97,63.00) = 9.81, p_HF < 0.001, ϵ² = 0.21, but those who played the Evaluative version did not. Socio-moral reasoning scores from both versions combined did not correlate with empathy or sense of presence during the game, though results neared significance. The study findings support preliminary validation of the game as a promising method for assessing and remediating social skills during adolescence.

Mistakes in interpersonal perceptions: Social cognition in aggressive forensic psychiatry patients

BACKGROUND

While there is an established link between untreated psychosis and aggression, an enhanced understanding of the role of social cognition is still needed.

AIMS

To examine social cognitive functioning among patients in a specialist forensic mental health service who had been deemed not criminally responsible for acts of violence due to a psychotic disorder. It was hypothesised, first, that such patients would show reduced social cognitive functioning compared with healthy, nonviolent comparison participants and, second, that those who continued to be aggressive while inpatients would demonstrate significant reductions compared to the now nonaggressive group.

METHODS

The study samples were of 10 recently aggressive and 15 not-recently aggressive patients and 20 healthy, nonviolent comparison participants. Each completed the Toronto Empathy Questionnaire (TEQ), the Reading the Mind in the Eyes Test-Revised (RMET) and the Interpersonal Perception Task-15 (IPT-15).

RESULTS

There was no significance between group differences on the RMET and TEQ. The patient group as a whole, however, showed significant interpersonal misperceptions, with specific misperceptions on IPT-15 deception and kinship subscales, while at the same time lacking self-awareness of their errors. Misperceptions on the IPT-15 competition subscale were unique to recently aggressive patients.

CONCLUSIONS

Select aspects of reduced social cognitive functioning were found among not criminally responsible patients with psychosis who had committed violent acts and who continued to act aggressively while forensic inpatients. These findings enhance our understanding of the role of social cognition in predisposing toward violence and the potential importance of incorporating interventions which improve social cognition directly. We suggest also the potential for future research using virtual reality technologies in treatment.
