Objective: The Self-Discrepancies Scale (S-DS) is a multiple-subscore instrument designed to assess discrepancies between mental representations of the self: the actual self on one hand, and the ideal and socially prescribed selves on the other. Its idiographic subscores rely on the endorsement of self-descriptive traits, while its abstract subscores form an overall judgement of felt self-discrepancies. The objectives of the present study were to (i) evaluate the S-DS in a new non-clinical population, (ii) expand the body of data on the S-DS's convergent validity, (iii) study the idiographic data for the S-DS, and (iv) establish a nomothetic list of traits with a better choice of unwanted traits.

Objectives: It is known that lockdown alters the mental health of children in general and adolescents in particular. Here, we surveyed the mental health of high school students returning to in-class lessons after the pandemic. We compared an "anxious-depressed" group with a "neither anxious nor depressed" group with regard to perceived self-efficacy.

Article Synopsis
  • The study investigates repetitive and restricted behaviors and interests (RRBI) in autism, classifying them into 'motor-driven' and 'cognitively driven' categories while considering the roles of clinical contexts and neuroanatomy.
  • Researchers analyzed data from 792 participants, including autistic individuals, their relatives, and typically developing individuals, using standardized scales and MRI to assess RRBI patterns and brain volumes.
  • The analysis revealed three main RRBI factors, with 'motor-driven' symptoms linked to lower putamen volumes, while 'cognitively driven' symptoms showed different associations with brain structure, highlighting the complexity of RRBI in autism.

Article Synopsis
  • - Autism spectrum disorder (ASD) is marked by challenges in social communication and repetitive behaviors, with maternal immune activation (MIA) during mid-pregnancy identified as a risk factor, affecting about 15% of those with ASD.
  • - This study hypothesized that individuals with ASD who experienced MIA would show greater socio-adaptive impairments compared to those without, analyzing data from 295 mother-child pairs, with findings indicating more severe socialization difficulties in the ASD-MIA group.
  • - Limitations of the study include its retrospective nature and a relatively small sample size, underscoring the need for larger prospective studies to explore the specific biological mechanisms behind the socio-adaptive challenges in ASD-MIA individuals.

Article Synopsis
  • - Autism spectrum disorder (ASD) often overlaps with various somatic conditions that can complicate diagnosis, making it crucial to systematically assess these co-occurring disorders during the initial diagnostic process for effective healthcare and long-term outcomes.
  • - A systematic review of clinical practice guidelines from 2005 to 2019 identified 14 guidelines with varying quality, underscoring the importance of clinical examinations and recommendations for consultations with specialists in fields like pediatrics and genetics for a thorough initial somatic assessment (ISA).
  • - The results highlight the necessity of screening for specific warning signs and suggest using a referral form to guide clinicians and enhance the coordination of care, which could also help improve data collection on somatic disorders associated with ASD. *

Article Synopsis
  • The study investigates sensory processing issues in autistic individuals, focusing on hypo and hyper-sensory sensitivities potentially linked to genetic factors affecting GABA-ergic and glutamatergic pathways.
  • Researchers analyzed the sensory profiles of 1136 participants (including autistic individuals, relatives, and controls) and found significant differences in sensory processing between these groups, with variability being a key factor.
  • While the new differential Short Sensory Profile (dSSP) provided useful insights, it struggled to distinguish between individuals with similar sensory symptom levels, suggesting a need for combining this score with genetic and other sensory assessments for better understanding of sensory processing in autism.

At its most basic level, the sense of self is built upon awareness of one's body and the face holds special significance as the individual's most important and distinctive physical feature. Multimodal sensory integration is pivotal to experiencing one's own body as a coherent visual "self" representation is formed and maintained by matching felt and observed sensorimotor experiences in the mirror. While difficulties in individual facial identity recognition and in both self-referential cognition and empathy are frequently reported in individuals with autism spectrum disorder (ASD), studying the effect of multimodal sensory stimulation in this population is of relevant interest.

Background: While adult outcome in autism spectrum disorder (ASD) is generally measured using socially valued roles, it could also be understood in terms of aspects related to health status - an approach that could inform on potential gender differences.

Methods: We investigated gender differences in two aspects of outcome related to health-status, i.e.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder, which affects 1 in 44 children and may cause severe disabilities. Besides socio-communicational difficulties and repetitive behaviors, ASD also presents as atypical sensorimotor function and pain reactivity. While chronic pain is a frequent co-morbidity in autism, pain management in this population is often insufficient because of difficulties in pain evaluation, worsening their prognosis and perhaps driving higher mortality rates.

Unlabelled: In recent years, many psycho-educational technologies were studied to address the school-related difficulties encountered by students with autism spectrum disorder (ASD). However, most of them remain individual-centered and do not consider the social environment. To fill this gap, this study reports on the user-centered design of a web-based support tool, which aims to support communication and coordination between parents, school staff and health professionals of middle and high school students with ASD, in the context of elaborating, implementing, and following an Individualized Education Plan.

Background: Inhibitory control and attention processing atypicalities are implicated in various diseases, including autism spectrum disorders (ASD). These cognitive functions can be tested by using visually guided saccade-based paradigms in children, adolescents and adults to determine the time course of such disorders.

Methods: In this study, using Gap, Step, Overlap and Antisaccade tasks, we analyzed the oculomotor behavior of 82 children, teenagers and adults with high functioning ASD and their peer typically developing (TD) controls in a two-year follow-up study under the auspices of the InFoR-Autism project.

Repetitive behaviors (RB) represent a wide spectrum of symptoms ranging from sensory-motor stereotypies to complex cognitive rituals, frequently dichotomized as low- and high-order sub-groups of symptoms. Even though these subgroups are considered as phenomenologically distinct in autism spectrum disorder (ASD) and obsessive-compulsive disorder (OCD), brain imaging and genetic studies suggest that they have common mechanisms and pathways. This discrepancy may be explained by the frequent intellectual disability reported in ASD, which blurs the RB expressivity.

The ability to recognize and express emotions from facial expressions are essential for successful social interactions. Facial Emotion Recognition (FER) and Facial Emotion Expressions (FEEs), both of which seem to be impaired in Autism Spectrum Disorders (ASD) and contribute to socio-communicative difficulties, participate in the diagnostic criteria for ASD. Only a few studies have focused on FEEs processing and the rare behavioral studies of FEEs in ASD have yielded mixed results.

Autism spectrum disorders (ASD) are heterogeneous and complex neurodevelopmental conditions that urgently need reliable and sensitive measures to inform diagnosis properly. The Reading the Mind in the Eyes Task (or Eyes Test from now on) is widely used for this purpose. A recent study showed that subcategories of items of the children version of the Eyes Test could be especially discriminative to distinguish ASD and control children.

Objectives: Different studies centered on social relationship issues among ADHD children struggled to provide a unicist explanation between primary social cognition process alteration on the one hand and a mere symptomatic outcome of the disorder triad on the other. Some authors support the idea of a potential "social phenotype" shared at a different intensity by Attention Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). The point of the study is to characterize this possible social disability in a French ADHD population and compare it to control subjects and subjects with Autism Spectrum Disorder (ASD).

Irritability and emotional lability have been shown to be severity and impairment factors in community and clinical sample studies and are frequent comorbid features of Attention Deficit Hyperactivity Disorder (ADHD). However, while irritability and emotional lability seem to be closely linked, the differential effect of these two features has received little attention. This study assessed the distinct associations of irritability and emotional lability on symptomatology in children with ADHD.

Background: Autism spectrum disorders (ASD) are characterized by abnormal neurodevelopment, genetic, and environmental risk factors, as well as immune dysfunctions. Several lines of evidence suggest alterations in innate immune responses in children with ASD. To address this question in adults with high-functioning ASD (hf-ASD), we sought to investigate the role of natural killer (NK) cells in the persistence of ASD.
