Polish Adaptation of the Social Communication Questionnaire (SCQ) and Female Autism Phenotype: An Investigation of Potentially Sex-Biased Items in the Screening Assessment and Their Impact on Scores

Cognitive strengths in neurodevelopmental disorders, conditions and differences: A critical review

Neurodevelopmental disorders are traditionally characterised by a range of associated cognitive impairments in, for example, sensory processing, facial recognition, visual imagery, attention, and coordination. In this critical review, we propose a major reframing, highlighting the variety of unique cognitive strengths that people with neurodevelopmental differences can exhibit. These include enhanced visual perception, strong spatial, auditory, and semantic memory, superior empathy and theory of mind, along with higher levels of divergent thinking. Whilst we acknowledge the heterogeneity of cognitive profiles in neurodevelopmental conditions, we present a more encouraging and affirmative perspective of these groups, contrasting with the predominant, deficit-based position prevalent throughout both cognitive and neuropsychological research. In addition, we provide a theoretical basis and rationale for these cognitive strengths, arguing for the critical role of hereditability, behavioural adaptation, neuronal-recycling, and we draw on psychopharmacological and social explanations. We present a table of potential strengths across conditions and invite researchers to systematically investigate these in their future work. This should help reduce the stigma around neurodiversity, instead promoting greater social inclusion and significant societal benefits.

Implementing an Early Detection Program for Autism Spectrum Disorders in the Polish Primary Healthcare Setting-Possible Obstacles and Experiences from Online ASD Screening

A screening questionnaire for autism symptoms is not yet available in Poland, and there are no recommendations regarding screening for developmental disorders in Polish primary healthcare. The aim of this study was to assess the opinions of parents and physicians on the legitimacy and necessity of screening for autism spectrum disorders, potential barriers to the implementation of the screening program, and the evaluation and presentation of the process of online ASD screening, which was part of the validation program for the Polish version of one of the screening tools. This study involved 418 parents whose children were screened online and 95 primary care physicians who expressed their opinions in prepared surveys. The results indicate that both parents and doctors perceive the need to screen children for ASD in the general population without a clear preference as to the screening method (online or in person). Moreover, online screening is considered by respondents as a satisfactory diagnostic method. Therefore, online screening may prove to be at least a partial method of solving numerous obstacles indicated by participants' systemic difficulties including time constraints, the lack of experienced specialists in the field of developmental disorders and organizational difficulties of healthcare systems.

Special considerations for assessing and caring for autism in girls and women

PURPOSE OF REVIEW

As the specificities of autistic women are increasingly recognized, this review aims to highlight emerging areas of research. These areas primarily focus on measurement bias of diagnostic tools, the physical and mental health of autistic women, and the unique aspects of the lives of autistic women, both personally and professionally across all life stages.

RECENT FINDINGS

Conventional diagnostic tools struggle to capture the specificities of autism in females, but more sensitive instruments like the GQ-ASC (Girls' Questionnaire for Autism Spectrum Conditions), later also referred to as Q-ASC (Questionnaire for Autism Spectrum Conditions) in the scientific literature, show better performances. Autistic women face particular challenges, including an increased risk of physical and mental health problems throughout their lives as women (puberty, motherhood, menopause). Autistic women also encounter specific difficulties in their employment that require greater consideration.

SUMMARY

The findings of this review identify research areas that need to be developed to better understand and support autistic girls and women and to enhance clinical practice for them.

Psychometric properties of Autism Spectrum Disorders Screening Assessment Tools: Systematic Review

Background

Due to the prevalence of autism spectrum disorder (ASD), these children must be screened as soon as possible and receive the necessary and appropriate treatment. The purpose of this study was to examine all the ASD screening tools and examine their psychometric properties in available languages.

Methods

This was a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to review the articles published between 2000 and 2023 and were published in PubMed, EMBASE, ProQuest, and Scopus databases. English keywords were as follows: autism spectrum disorders (ASD), screening/screen, tools, psychometric properties, validity, reliability, translations, pervasive developmental disorders (PDD), and children. The COnsensus -based Standards for the selection of health Measurement Instruments (COSMIN) checklist were used to investigate the psychometric properties of the studies.

Results

Among the 476 primary studies, 35 ASD screening tools (132 articles related to the psychometric properties of 35 ASD screening tools in different languages) were identified based on our criteria, and their psychometric properties were examined. Various tools, including performance-based, direct observation, interactive play, and parent and teacher reports tools, were included in the list of tools.

Conclusion

Considering that each of these tools has advantages and limitations, they need to be selected and used according to the goals of the researchers and the therapists. Another important point is that many of these tools still need more extensive studies in relation to their psychometric properties.

The psychometric properties of the Greek version of the Social Communication Questionnaire

There is a scarcity of diagnostic assessments and screening tools for autism spectrum disorders (ASD) in Greek. In this study, we examined the psychometric properties of the recently developed Greek version of the Social Communication Questionnaire (SCQ). We used parental responses for 311 children (mean age: 7.54 years old, SD = 1.92), 122 with a diagnosis of ASD (93 boys, 29 girls) and 189 neurotypical children (104 boys, 85 girls), with 167 responses referring to the Lifetime and 144 to the Current form of the SCQ. Both forms presented adequate construct validity based on the four‐factor model, while in both forms, autistic children presented higher SCQ total and subscale scores (four factors) than typical children. The forms had excellent internal reliability. An item‐response‐theory analysis suggested that over 80% of test items fitted adequately a Rasch model, while a preliminary analysis of gender biases suggested that a small number of items (Lifetime: five; Current: six out of 39) were differentially sensitive to autistic symptomatology in boys and girls. A receiver‐operating‐characteristic analysis showed excellent diagnostic performance based on the SCQ total score (Lifetime: area‐under‐the‐curve/AUC = 0.937, Current: AUC = 0.963), and acceptable to excellent discrimination for the four subscales (AUCs between 0.737 and 0.955). Our preliminary results suggest that the Greek SCQ presents satisfactory psychometric properties and can be used for differentiating children with ASD from typical children in initial assessments within clinical and research settings.

Sex Differences in Autism Spectrum Disorder: Diagnostic, Neurobiological, and Behavioral Features

Autism Spectrum Disorder (ASD) is a complex neurodevelopmental disorder with a worldwide prevalence of about 1%, characterized by impairments in social interaction, communication, repetitive patterns of behaviors, and can be associated with hyper- or hypo-reactivity of sensory stimulation and cognitive disability. ASD comorbid features include internalizing and externalizing symptoms such as anxiety, depression, hyperactivity, and attention problems. The precise etiology of ASD is still unknown and it is undoubted that the disorder is linked to some extent to both genetic and environmental factors. It is also well-documented and known that one of the most striking and consistent finding in ASD is the higher prevalence in males compared to females, with around 70% of ASD cases described being males. The present review looked into the most significant studies that attempted to investigate differences in ASD males and females thus trying to shade some light on the peculiar characteristics of this prevalence in terms of diagnosis, imaging, major autistic-like behavior and sex-dependent uniqueness. The study also discussed sex differences found in animal models of ASD, to provide a possible explanation of the neurological mechanisms underpinning the different presentation of autistic symptoms in males and females.
