High Levels Of Autistic Traits Research Articles

EXPRESS: Reasoning in Social versus Non-social Domains and its Relation to Autistic Traits.

Enhanced rationality has been linked to higher levels of autistic traits, characterised by increased deliberation and decreased intuition, alongside reduced susceptibility to common reasoning biases. However, it is unclear whether this is domain-specific or domain-general. We aimed to explore whether reasoning tendencies differ across social and non-social domains in relation to autistic traits. We conducted two experiments (N1 = 72, N2 = 217) using a reasoning task with social and non-social scenario comparisons to evaluate the specific information participants used when making judgments about children, in the social domain, and objects, in the non-social domain. We consistently found a greater reliance on behaviour-based information in the non-social domain, compared to the social domain, indicating a more deliberative approach. In Experiment 1, we found a correlation between autistic traits and the proportion of behaviour-based information, suggesting a more deliberative approach, when making judgments about children, and not about objects. In Experiment 2, with a larger sample, shortened version of the reasoning task, and requests for written justification, we did not identify a significant correlation between these variables. With this study, we introduce a novel scenario-based reasoning task that systematically compares the social and non-social domains. Our findings highlight the complex nature of the relationship between reasoning style and autistic traits.

Validation of the camouflaging autistic traits questionnaire short form (CATQ-SF)

BackgroundCamouflaging of autistic traits involves hiding or compensating for autistic characteristics, often due to stigma or a desire to fit in with others. This behaviour has been associated with mental health issues in autistic individuals. The 2 5-item Camouflaging Autistic Traits Questionnaire (CAT-Q) is the most commonly used self-report measure of camouflaging. In this study, a 9-item short form version was developed for use in clinical and research settings. Aims: To construct and psychometrically validate a brief self-report measure of camouflaging. MethodThe Camouflaging Autistic Traits Questionnaire – Short Form (CATQ-SF) was developed and its factor structure and psychometric properties were evaluated in two studies. Study 1 used a large, online sample of autistic and non-autistic adults (N = 832) to evaluate the factor structure, psychometric properties, and measurement invariance of the CATQ-SF. Study 2 used an independent sample of autistic and non-autistic adults (N = 80) to test Study 1's findings. ResultsIn Study 1, evidence for a three-factor structure was observed, with good internal consistency (combined autistic & non-autistic α = 0.84). In addition, the instrument demonstrated measurement invariance, and reliably predicted higher levels of autistic traits. In Study 2, the 3-factor structure was replicated, and good internal consistency was again observed (combined autistic and non-autistic α = 0.89). In both studies, psychometric properties were of similar or higher validity compared to the full-form CAT-Q. ConclusionsThe CATQ-SF can be used by clinicians and researchers to measure camouflaging in autistic and non-autistic adults quickly and reliably.

Autistic traits are associated with differences in the perception of genuineness and approachability in emotional facial expressions, independently of alexithymia.

People with autism and higher levels of autistic traits often have difficulty interpreting facial emotion. Research has commonly investigated the association between autistic traits and expression labeling ability. Here, we investigated the association between two relatively understudied abilities, namely, judging whether expressions reflect genuine emotion, and using expressions to make social approach judgements, in a nonclinical sample of undergraduates at an Australian university (N = 149; data collected during 2018). Autistic traits were associated with more difficulty discriminating genuineness and less typical social approach judgements. Importantly, we also investigated whether these associations could be explained by the co-occurring personality trait alexithymia, which describes a difficulty interpreting one's own emotions. Alexithymia is hypothesized to be the source of many emotional difficulties experienced by autistic people and often accounts for expression labeling difficulties associated with autism and autistic traits. In contrast, the current results provided no evidence that alexithymia is associated with differences in genuineness discrimination and social approach judgements. Rather, differences varied as a function of individual differences in specific domains of autistic traits. More autistic-like social skills and communication predicted greater difficulty in genuineness discrimination, and more autistic-like social skills and attention to details and patterns predicted differences in approach judgements. These findings suggest that difficulties in these areas are likely to be better understood as features of the autism phenotype than of alexithymia. Finally, results highlight the importance of considering the authenticity of emotional expressions, with associations between differences in approach judgements being more pronounced for genuine emotional expressions.

Mental wellbeing, but not prison climate, mediates the association between autistic traits and treatment readiness among men with sexual convictions

ABSTRACT Research suggests that autistic individuals have qualitatively unique experiences of prison social environments, and that these experiences may have implications for autistic prisoners’ mental wellbeing and engagement with offending behaviour interventions. However, this has yet to be quantitatively tested. Using a sample of 177 adult prisoners from two UK prisons that exclusively house individuals with sexual convictions, this study tested a hypothesised double-mediation model, to investigate associations between autistic traits and prisoners’ readiness to engage with treatment, and whether this was mediated by experiences of the prison social climate and mental wellbeing. Results indicated that prisoners with higher levels of autistic traits had poorer experiences of prison social climates, which, in turn, predicted higher levels of anxiety and depression, which subsequently predicted reduced level readiness to engage with offending behaviour interventions. Implications for research and practice are discussed, emphasising the need for increased autism-related awareness and support provisions in prisons. PRACTICE IMPACT STATEMENT The present study is a novel quantitative study, which is the first to statistically demonstrate that neurodivergence can significantly influence prisoners’ perceptions of prison social climates, mental wellbeing, and ultimately readiness to engage with rehabilitate interventions. As such, these findings emphasise the importance of embedding understanding neurodiversity in prison staff training, as well as considering and accommodating neurodiversity as a key dimension in the development of a prison’s rehabilitative culture.

"Don't talk to me like Iam an illness": exploring patients' needs using the communication passport in an eating disorder service.

Social challenges are common in patients with eating disorders (ED). The presence of autistic characteristics often exacerbates social difficulties within this group, potentially affecting treatment outcomes. This study investigates the communication preferences, challenges, dislikes, and support needs of patients with ED, both with and without autistic traits, using acommunication passport in anational inpatient ED service. An explorative qualitative analysis of 38 completed communication passports was conducted to investigate patients' communication preferences, sensory needs, struggles and dislikes, and areas of support required, paying particular attention to the distinct needs of patients with high levels of autistic traits. The communication passport provided valuable insights into patients' communication preferences, sensory sensitivities, challenges, and support needed. Patients also used the passports to share information about their strengths, personal identity, and life beyond the hospital. The communication passport fosters adeeper understanding of patients' needs and may support clinicians in care planning and communication strategies tailored to each patient's needs. Regular evaluation and updates are warranted to ensure its usability and accessibility by the wider care team.

Differences in audiovisual temporal processing in autistic adults are specific to simultaneity judgments.

Research has shown that children on the autism spectrum and adults with high levels of autistic traits are less sensitive to audiovisual asynchrony compared to their neurotypical peers. However, this evidence has been limited to simultaneity judgments (SJ) which require participants to consider the timing of two cues together. Given evidence of partly divergent perceptual and neural mechanisms involved in making temporal order judgments (TOJ) and SJ, and given that SJ require a more global type of processing which may be impaired in autistic individuals, here we ask whether the observed differences in audiovisual temporal processing are task and stimulus specific. We examined the ability to detect audiovisual asynchrony in a group of 26 autistic adult males and a group of age and IQ-matched neurotypical males. Participants were presented with beep-flash, point-light drumming, and face-voice displays with varying degrees of asynchrony and asked to make SJ and TOJ. The results indicated that autistic participants were less able to detect audiovisual asynchrony compared to the control group, but this effect was specific to SJ and more complex social stimuli (e.g., face-voice) with stronger semantic correspondence between the cues, requiring a more global type of processing. This indicates that audiovisual temporal processing is not generally different in autistic individuals and that a similar level of performance could be achieved by using a more local type of processing, thus informing multisensory integration theory as well as multisensory training aimed to aid perceptual abilities in this population.

Exploring the association between social camouflaging and self- versus caregiver-report discrepancies in anxiety and depressive symptoms in autistic and non-autistic socially anxious adolescents.

Social camouflaging or masking refers to strategies autistic individuals adopt to hide their autism persona when trying to fit in. It is unclear whether camouflaging is only applicable to social differences unique to autism, or more generally to any types of social difference, such as experiences of mental health difficulties. We asked 43 autistic and 39 non-autistic adolescents (aged 14-19 years, all of whom showed similarly high levels of social anxiety) and their primary caregivers to complete questionnaires about their mental health (anxiety and depression) and autistic traits, and adolescents self-reported camouflaging behaviours. We wondered if camouflaging may be used to hide mental health difficulties reported by young people and affect caregiver report on symptom severity. We found that adolescents who self-reported greater levels of autistic traits, anxiety and depression symptoms compared with their caregivers reported greater camouflaging. Adolescents who agreed on having high levels of autistic traits and anxiety symptoms with their caregivers reported greater camouflaging behaviours. We discuss how having high levels of autistic traits and anxiety may increase adolescents' camouflaging behaviours to hide social differences, which may contribute towards poor mental health outcomes. We think it is important to talk with adolescents about how camouflaging social and mental health difference can have negative impacts for mental health as well as possible positive social gains.

Intolerance of Uncertainty and Anxiety (but not Alexithymia) Mediate the Association Between Autistic Traits and Quality of Life.

Previous research has indicated that autistic individuals report lower quality of life (QoL) than non-autistic people. It is unclear whether it is the autism traits themselves or co-occurring thinking styles or mental health difficulties that most impair QoL. This study tested a hypothesised model to explore how 'intolerance of uncertainty' (IU), alexithymia (difficulty in identifying and describing own emotions), and anxiety play into the association between autistic traits and QoL. Online survey data were analysed from 116 autistic and 51 non-autistic adults who completed six standardised questionnaires measuring autistic traits, alexithymia, IU, anxiety and QoL (physical health, psychological health, social relations, and environment domains). The autistic group reported higher scores for alexithymia, IU and anxiety, and lower scores for QoL across domains, compared to the non-autistic group. Across the entire sample, autistic traits, alexithymia, IU and anxiety were positively correlated with one another, and negatively related to the four domains of QoL. Finally, IU and anxiety partially serially mediated the pathways from autistic traits to physical health and environment domains of QoL, and fully mediated the pathways from autistic traits to psychological health and social relations domains of QoL, across the full sample. The lower QoL experienced by autistic people may be explained in part by the mediating effect of both IU and anxiety (but not alexithymia). This study highlights the need for evidence-based interventions to address both IU and anxiety to improve QoL for autistic people/those with high levels of autistic traits.

Autistic Traits and Aggressive Behavior in Chinese College Students: A Serial Mediation Model and the Gender Difference.

The existence of aggressive behavior in autism spectrum disorders (ASD) raises questions about whether cognitive and emotional factors in social information processing play a role between autistic traits (ATs) and aggressive behavior in the general population, especially in the context of Chinese culture. Moreover, given a possible gender difference in these variables, the study aimed to examine the effect of ATs on aggressive behavior, and the potential mediating role of hostile attribution bias and alexithymia on this association, as well as gender difference. 850 Chinese college students participated in the assessment, including their ATs, hostile attribution bias, alexithymia, and aggressive behavior. Pearson correlation, mediation effects analyses, and multiple-group comparison were conducted. The results indicated that ATs indirectly predicted increased aggressive behavior through attribution bias and alexithymia. Gender difference in mediating effects was revealed: ATs indirectly predicted increased aggressive behavior through the serial mediating effect only in males. Hostile attribution bias and alexithymia completely mediated the association between ATs and aggressive behavior, which contained the separate mediating effects of (a) hostile attribution bias and (b) alexithymia and the serial mediating effect of (c) hostile attribution bias and alexithymia. Gender differences in mediating effects were found only in the serial mediating effect, which was significant in males but not in females. The findings revealed the internal mechanism of ATs affecting aggressive behavior and gender difference, which have implications for the intervention of aggressive behavior of individuals with autism and those with high levels of ATs.

Individuals with high levels of autistic traits exhibit impaired cognitive but not affective theory of mind and empathy.

Theory of mind (ToM) and empathy are considered key components of social cognition that are often impaired in individuals with autism spectrum disorders (ASD). However, it remains unclear whether individuals with high levels of autistic traits exhibit similar impairments in these two functions. This study examined the affective and cognitive domains of ToM and empathy in individuals with high levels of autistic traits. We recruited 84 participants with high levels and 78 participants with low levels of autistic traits to complete a set of self-reported checklists and performance-based tasks capturing affective and cognitive components of ToM and empathy. The results showed that participants with high levels of autistic traits exhibited significant impairments in cognitive but not in affective ToM and empathy compared with their counterparts with low levels of autistic traits. We also found that empathy impairments in people with high levels of autistic traits were confounded by alexithymia and depressive traits.

Maternal Autistic Traits and Adverse Birth Outcomes

Women with a high level of autistic traits in the general population may experience larger health disparities during pregnancy, particularly women diagnosed with autism spectrum disorder (ASD), which in turn may be associated with increased risk of adverse birth outcomes. To investigate the association between maternal autistic traits and the risk of adverse birth outcomes in the general population. This cohort study included mothers of singletons from a nationwide, multicenter prospective birth cohort, the Japan Environmental Children's Study. Expecting mothers were recruited between January 2011 and March 2014. Data were analyzed between June 2021 and November 2023. Autistic traits were self-reported during the second and third trimesters using the short form of the Autism-Spectrum Quotient Japanese version (AQ-J10) (score range, 0-10; clinical range, ≥7). Data on preterm birth (<37 weeks' gestation) and neonates born small for gestational age (SGA) were transcribed from medical records. Additional analysis of gestational age groups (very preterm birth, <32 weeks' gestation; moderate-to-late preterm birth, 32-36 weeks' gestation) was also performed. Among 87 687 women (mean [SD] age, 31.2 [5.0] years) included in the study, 2350 (2.7%) had AQ-J10 scores within the clinical range yet only 18 (0.02%) were diagnosed with ASD. A higher AQ-J10 score was associated with an increased risk of all birth outcomes, including preterm births (relative risk [RR] per 1-SD increase, 1.06; 95% CI, 1.03-1.09), moderate-to-late preterm births (RR per 1-SD increase, 1.05; 95% CI, 1.01-1.08), very preterm births (RR per 1-SD increase, 1.16; 95% CI, 1.06-1.26), and child born SGA (RR per 1-SD increase, 1.04; 95% CI, 1.01-1.06) after adjusting for maternal and pregnancy-related factors. The risks of all outcomes increased with higher AQ-J10 scores; compared with women below the clinical range, women within the clinical range had greater risk of preterm births (RR, 1.16; 95% CI, 1.07-1.26), moderate-to-late preterm births (RR, 1.12; 95% CI, 1.03-1.22), very preterm births (RR, 1.49; 95% CI, 1.18-1.89), and a child born SGA (RR, 1.11; 95% CI, 1.04-1.19). In this cohort study, higher level of maternal autistic traits was associated with increased risk of adverse birth outcomes, particularly very preterm birth. Acknowledging the risks and providing tailored and timely antenatal care support to women with a high level of autistic traits in the general population, particularly women with autistic traits within the clinical range, regardless of formal diagnosis, is warranted.

Presence and correlates of autistic traits among patients with social anxiety disorder.

Due to their similar behavioral presentation, it can sometimes be challenging to distinguish between a social anxiety disorder (SAD) and the social avoidance that is frequently described in autism spectrum disorder (ASD). Moreover, a growing body of evidences is reporting that a significant proportion of subjects with ASD also meet the requirements for SAD and, vice versa, subjects with SAD tend to exhibit a higher prevalence of autistic traits. In this framework, the current study aims to evaluate prevalence and correlates of autistic traits in a sample of adult subjects diagnosed with SAD and healthy controls (HC), also evaluating which autism spectrum dimensions may statistically predict higher SAD symptoms. 56 subjects with a clinical diagnosis of SAD and 56 gender and age matched HC were recruited from the Psychiatric Clinic of the University of Pisa. Subjects were assessed with the SCID-5, the Social Anxiety Spectrum - Short Version (SHY- SV) and the Adult Autism Subthreshold Spectrum (AdAS Spectrum). SAD group scored significantly higher in all AdAS Spectrum and SHY-SV domains and total score compared to the HC group with no significant gender difference. SHY-SV total and domain scores, were strongly and positively and strongly correlated with all AdAS Spectrum domains and total score. AdAS Spectrum total score and Childhood/Adolescence, Non-Verbal Communication, Empathy and Restricted interests and Rumination domain scores score were significant predictors of higher SHY-SV score. Our results confirm the link between SAD and autistic traits also in adult population, describing not only high levels of autistic traits in SAD adults, but also significant correlations between many core features of the two disorders and a predictive role of autistic traits on higher SAD symptoms.

The search for gastrointestinal inflammation in autism: a systematic review and meta-analysis of non-invasive gastrointestinal markers

BackgroundGastrointestinal symptoms and inflammatory gastrointestinal diseases exist at higher rates in the autistic population. It is not clear however whether autism is associated with elevated gastrointestinal inflammation as studies examining non-invasive faecal biomarkers report conflicting findings. To understand the research landscape and identify gaps, we performed a systematic review and meta-analysis of studies measuring non-invasive markers of gastrointestinal inflammation in autistic and non-autistic samples. Our examination focused on faecal biomarkers as sampling is non-invasive and these markers are a direct reflection of inflammatory processes in the gastrointestinal tract.MethodsWe extracted data from case–control studies examining faecal markers of gastrointestinal inflammation. We searched PubMed, Embase, Cochrane CENTRAL, CINAHL, PsycINFO, Web of Science Core Collection and Epistemonikos and forward and backwards citations of included studies published up to April 14, 2023 (PROSPERO CRD42022369279).ResultsThere were few studies examining faecal markers of gastrointestinal inflammation in the autistic population, and many established markers have not been studied. Meta-analyses of studies examining calprotectin (n = 9) and lactoferrin (n = 3) were carried out. A total of 508 autistic children and adolescents and 397 non-autistic children and adolescents were included in the meta-analysis of calprotectin studies which found no significant group differences (ROM: 1.30 [0.91, 1.86]). Estimated differences in calprotectin were lower in studies with siblings and studies which did not exclude non-autistic controls with gastrointestinal symptoms. A total of 139 autistic participants and 75 non-autistic controls were included in the meta-analysis of lactoferrin studies which found no significant group differences (ROM: 1.27 [0.79, 2.04]).LimitationsAll studies included in this systematic review and meta-analysis examined children and adolescents. Many studies included non-autistic controls with gastrointestinal symptoms which limit the validity of their findings. The majority of studies of gastrointestinal inflammation focused on children under 12 with few studies including adolescent participants. Most studies that included participants aged four or under did not account for the impact of age on calprotectin levels. Future studies should screen for relevant confounders, include larger samples and explore gastrointestinal inflammation in autistic adolescents and adults.ConclusionsThere is no evidence to suggest higher levels of gastrointestinal inflammation as measured by calprotectin and lactoferrin are present in autistic children and adolescents at the population level. Preliminary evidence suggests however that higher calprotectin levels may be present in a subset of autistic participants, who may be clinically characterised by more severe gastrointestinal symptoms and higher levels of autistic traits.

Higher levels of neurodivergent traits associated with lower levels of self-efficacy and wellbeing for performing arts students

This study identifies the extent to which autistic students, or those with high levels of autistic traits, are pursuing higher education in the performing arts, and examined the nature of the relationship between students’ autistic traits and reported wellbeing. Performing arts students ( n = 280), along with a comparison group of students studying other subjects ( n = 144), took part in an online questionnaire about their background (diagnostic history, neurodivergent traits), and their wellbeing (perceived educational self-efficacy, quality of life, mental health). Participants also answered open-ended questions about support needed, received, or desired, in their educational institution. Similar rates of autism diagnoses and levels of autistic traits were seen in the two groups. Regression analyses indicated that higher levels of ADHD traits and depression were associated with lower levels of educational self-efficacy. Despite a significant negative correlation between autistic traits and self-efficacy, autistic traits did not uniquely predict variance in the regression model. One third of all students reported a desire for more education-based support, particularly those with ADHD traits. These findings show that, within the community of those studying in the performing arts, those who are neurodivergent or who have high levels of neurodivergent traits, may be especially vulnerable to lower wellbeing. Lay Summary Many autistic people want to have a career in the performing arts and therefore are likely to undertake performing arts degree programmes. This study looked at the experiences of autistic students, or those with high levels of autistic traits. We wanted to understand how being autistic, or having a high level of autistic traits, might relate to student wellbeing – and whether this was specific to performing arts courses. In total, 280 performing arts students and 144 students studying other subjects (a comparison group), answered an online questionnaire about their wellbeing as a student. This included questions about how good they thought they were at different parts of the course, their quality of life, their mental health, their level of autistic and ADHD traits, and their experiences of support during their studies. We found similar numbers of autistic people and levels of autistic and ADHD traits in students from the two groups (performing arts and other subjects). For both student groups, we found that a higher level of ADHD traits and mental health conditions predicted lower confidence in people's abilities. Higher levels of autistic traits were also linked with lower educational confidence, but did not predict it as much as ADHD or mental health traits did. One third of all students said they wanted more support during their course, and these students tended to have higher levels of ADHD traits. Our findings show that students who are autistic, or who have high levels of autistic traits, may be particularly at risk of lower wellbeing while studying.

Cognitive Profile of Children with Autistic Traits

Background Three neuropsychological theories have been extensively studied in both autism spectrum disorders and the broader autism phenotype ndash Theory of Mind Executive Function and Central Coherence. The exact profile is still under debate.Objective The objective of this study was to compare the neuropsychological profile of children with high and low levels of autistic traits. Methodology Around 771 children between the ages of 5 and 11 years from mainstream schools were assessed using the Social Responsiveness Scale SRS. Two hundred children among the 771 assessed children were administered a battery of neuropsychological tests. Further the SRS scores were subjected to factor analysis FA and the 28 items from the SRS which were common across factor analyses were taken and scores were recalculated based on these items. The neuropsychological profiles on this were further compared.Results Executive Function difficulties were apparent among the high scorers across all comparisons. Children with higher levels of autistic traits post FA had weaker central coherence. The difference in central coherence was apparent even when the comparison was made without the lower socio-economic group. While there was no significant difference in the performance on the Theory of Mind there was a trend towards significance in the group without the lower socio-economic group.Conclusion Executive function deficits are strongly associated with higher levels of autistic traits. The influence of Central Coherence is apparent only when the autistic traits are more closely woven. Theory of Mind appears to be a more downstream effect of Executive Function and Central Coherencenbsp

Metabolic syndrome in adults with autistic traits: associated psychological, behavioral, and biological factors in females and males - a PharmLines initiative.

While cardiovascular diseases is highly prevalent and an important cause of mortality in autistic adults, knowledge on their increased cardiovascular risk is limited. Hence, this study aimed to investigate psychological, behavioral, and physical factors associated with metabolic syndrome (MetS) in adults with autistic traits. In total, 17,705 adults from the Lifelines Cohort were included and categorized using Autism Spectrum Quotient-10 sum-scores. The quartiles with highest (HQ-traits-group females: n = 2,635; males: n = 1803) and lowest levels of autistic traits (LQ-traits-group, n = idem) were analyzed. Using multivariable logistic regression, the associations between MetS and (self-reported and interviewed) psychological, behavioral, and physically measured factors in these stratified groups were investigated. Among females, MetS was more common in the HQ-traits-group than in the LQ-traits-group (10.0% versus 7.5%, p < 0.01), while this was not the case among males (HQ-traits-group 13.8% versus LQ-traits-group 13.1%, p = 0.52). In both the female and male HQ-traits-group, the presence of MetS was associated with poorer self-reported health, less daily physical activity, and altered leukocyte counts. These findings underline the relevance of adequate cardiovascular prevention in adults with higher levels of autistic traits. Future research could gain more insight into the relationship between cardiovascular risk and autistic traits in females, and into tailored cardiovascular prevention.

Profiling Autism and Attention Deficit Hyperactivity Disorder Traits in Children with SYNGAP1-Related Intellectual Disability.

SYNGAP1-related ID is a genetic condition characterised by global developmental delay and epilepsy. Individuals with SYNGAP1-related ID also commonly show differences in attention and social communication/interaction and frequently receive additional diagnoses of Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD). We thus set out to quantify ASD and ADHD symptoms in children with this syndrome. To assess ASD and ADHD, parents and caregivers of a child with SYNGAP1-related ID (N = 34) or a typically developing control (N = 21) completed the Social Responsiveness Scale-2, the Social Communication Questionnaire with a subset of these also completing the Conners-3. We found that those with SYNGAP1-related ID demonstrated higher levels of autistic traits on both the SRS and SCQ than typically developing controls. On the SRS, those with SYNGAP1-related ID scored highest for restricted repetitive behaviours, and were least impaired in social awareness. On the Conners-3, those with SYNGAP1-related ID also showed a high prevalence of ADHD traits, with scores demonstrating difficulties with peer relations but relatively low occurrence of symptoms for DSM-5 conduct disorder and DSM-5 oppositional defiant disorder. Hierarchical clustering analysis highlighted distinct SYNGAP1-related ID subgroups for both ASD and ADHD traits. These findings provide further characterisation of the SYNGAP1-related ID behavioural phenotype, guiding diagnosis, assessment and potential interventions.

The valence-specific empathy imbalance hypothesis of autism: The role of autistic traits, alexithymia, emotion dysregulation, and gender differences

Individuals exhibiting pronounced autistic traits (e.g., social differences and specialised interests) may struggle with cognitive empathy (i.e., the ability to infer others' emotions), although the relationship with affective empathy (i.e., the ability to share others' emotions) is less clear in that higher levels of autistic traits may be linked with increased affective empathy for negative emotions but reduced affective empathy for positive emotions. The current study investigates this empathy profile and whether alexithymia and emotion dysregulation help to explain it. Results from 322 university students' questionnaire responses suggested that more pronounced autistic traits were linked to reduced cognitive empathy and affective empathy for positive emotions but increased affective empathy for negative emotions. Alexithymia and emotion dysregulation helped to explain the reduced cognitive empathy and the increased affective empathy for negative emotions. However, neither explained the reduced affective empathy for positive emotions. Finally, gender-moderated relationships suggest different empathy presentations across males and females. The results support the valence-specific empathy imbalance hypothesis of autism and highlight the critical roles of co-occurring alexithymia and emotion dysregulation.

Long-term Memory of Sensory Experiences from the First Pregnancy, its Peri-partum and Post-partum in Women with Autism Spectrum Disorders without Intellectual Disabilities: A Retrospective Study

PurposeTo explore the recalled experience of pregnancy and motherhood in women diagnosed with Autism Spectrum Disorders (ASD) without intellectual disabilities, focusing on sensory perceptions and mood.MethodsWe retrospectively evaluated, through an ad-hoc structured interview, the sensory sensitivity during the pre-partum, the peri-partum, and the post-partum of thirty-three mothers with ASD and thirty-two neurotypical mothers. Participants also underwent a psychometric assessment about autistic traits, general sensory sensitivity, and post-partum depressive symptomatology.ResultsMothers with ASD recalled a higher sensitivity than the comparison group across the three time-points; however, during the peri-partum their recalled hypersensitivity decreases, and in the post-partum it returned as high as before childbirth. The difference in the length of recall between groups did not statistically influence our results. Higher levels of autistic traits correlated with higher depressive post-partum symptomatology.ConclusionsMothers with ASD seem to recall their experience of pregnancy, childbirth, and post-partum period differently from neurotypical mothers, particularly in terms of hypersensitivity. The correlation with depressive symptoms and the potential role of oxytocin and of long-term memory (encoding and recollection) are discussed. Further exploring these aspects might give fundamental hints to provide tailored support to mothers with ASD during pregnancy and motherhood.

Developmental prediction modeling based on diffusion tensor imaging uncovering age-dependent heterogeneity in early childhood autistic brain

ObjectiveThere has been increasing evidence for atypical white matter (WM) microstructure in autistic people, but findings have been divergent. The development of autistic people in early childhood is clouded by the concurrently rapid brain growth, which might lead to the inconsistent findings of atypical WM microstructure in autism. Here, we aimed to reveal the developmental nature of autistic children and delineate atypical WM microstructure throughout early childhood while taking developmental considerations into account.MethodIn this study, diffusion tensor imaging was acquired from two independent cohorts, containing 91 autistic children and 100 typically developing children (TDC), aged 4–7 years. Developmental prediction modeling using support vector regression based on TDC participants was conducted to estimate the WM atypical development index of autistic children. Then, subgroups of autistic children were identified by using the k-means clustering method and were compared to each other on the basis of demographic information, WM atypical development index, and autistic trait by using two-sample t-test. Relationship of the WM atypical development index with age was estimated by using partial correlation. Furthermore, we performed threshold-free cluster enhancement-based two-sample t-test for the group comparison in WM microstructures of each subgroup of autistic children with the rematched subsets of TDC.ResultsWe clustered autistic children into two subgroups according to WM atypical development index. The two subgroups exhibited distinct developmental stages and age-dependent diversity. WM atypical development index was found negatively associated with age. Moreover, an inverse pattern of atypical WM microstructures and different clinical manifestations in the two stages, with subgroup 1 showing overgrowth with low level of autistic traits and subgroup 2 exhibiting delayed maturation with high level of autistic traits, were revealed.ConclusionThis study illustrated age-dependent heterogeneity in early childhood autistic children and delineated developmental stage-specific difference that ranged from an overgrowth pattern to a delayed pattern.Trial registration This study has been registered at ClinicalTrials.gov (Identifier: NCT02807766) on June 21, 2016 (https://clinicaltrials.gov/ct2/show/NCT02807766).
