How Many Autistic Children are there in Colombia? A Nationwide Examination of Autism Through Health System Data.

Accurate healthcare data is indispensable for monitoring the epidemiology of autism spectrum disorders (ASD) and improving the quality of care for individuals on the spectrum. In Colombia, the Ministry of Health has developed the social protection information system (SISPRO) as a comprehensive registry, drawing data from the healthcare system with close to universal coverage (approximately 95%). This study utilizes data gathered by SISPRO to estimate the prevalence and specific characteristics of autistic children registered between January 2020 and December 2022. A descriptive epidemiological approach was employed, using the International Statistical Classification of Diseases as search terms for ASD within the SISPRO dataset. The study revealed a prevalence of 13.788 cases per 10,000 children in 2022 among aged 4 to 14. Regarding healthcare coverage types in 2022, the majority of autistic children served were under the contributory regime (68.28%), followed by the subsidized regime (25.36%). Geographic analysis indicated a non-uniform distribution of ASD prevalence in Colombia. The regions with the highest GDP, such as Antioquia, Atlántico, Bogotá, Cundinamarca, and Valle del Cauca, exhibited the highest prevalence (M = 17.90; SD = 14.3). In contrast, areas with the lowest GDP, including Amazonas, Guainía, Vaupés, Vichada, and Guaviare, showed the lowest prevalence among children (M = 2.6; SD = 2.5). The estimation of ASD prevalence in Colombia represents an ongoing initiative to inform public policy actions. During the COVID-19 pandemic, there was a decrease in the number of autistic children served by the healthcare sector; however, the prevalence of ASD changed to higher levels in 2022. These findings contribute to strategies aimed at improving the quality of life for autistic individuals and mitigating the economic burden on their families.

Prevalence and treatment of autism spectrum disorder in the United States, 2016-2022.

This study aims to assess the prevalence of Autism Spectrum Disorder (ASD) and its treatment. The study population was children aged 3-17 years with information on current ASD from National Survey of Children's Health, 2016-2022. Analysis of treatment was also conducted within the population of children with a current ASD diagnosis. A multivariate log-binomial regression model was used to assess the change of current ASD prevalence and ASD treatment by two study period (prior to COVID-19 pandemic: 2016-2019; during COVID-19 pandemic: 2020-22) and sociodemographic information. Compared to the current ASD at 2.5% in 2016, it increased to 3.6% in 2022. The treatment has decreased from 70.5% in 2016 to 61.6% in 2022 for any treatment and from 27.2% in 2016 to 20.4% in 2022 for medication treatment. Compared to children from 2016-2019, children from the following group were more likely to have ASD diagnosis during the pandemic (2020-2022), including those aged 3-5 years (aPR = 1.66, 95%CI 1.29-2.13), non-Hispanic white children, children from family with above national family income, and those with private insurance. However, medication treatment almost halved during the pandemic for non-Hispanic black children (aPR = 0.49, 95%CI 0.26-0.93) and children born overseas. In conclusion, higher prevalence of ASD might indicate a better awareness of ASD. The reduction in treatment correlates to the health service disruption caused by the pandemic, highlighting the needs of policy efforts to improve treatment for ASD.

Autism spectrum disorder, radicalization, and violence: a forensic perspective

ABSTRACT Some research suggests a higher prevalence of Autism Spectrum Disorder (ASD) among terrorist offenders in comparison to the general population. However, the literature does not achieve consistency in terms of an evidential and theoretical basis that individuals with ASD are especially susceptible to terrorism engagement. Through a case-series analysis, this paper discusses the interplay between ASD and radicalization. We examine how core ASD traits may increase one’s susceptibility to adopting radical ideology, and how internet exposure may contribute to the radicalization process. We comment on how vulnerability may lead to risk, distinguishing between these concepts, and argue that while individuals with ASD may not experience an increased risk of terrorism engagement, traits associated with ASD may increase one’s vulnerability to becoming radicalized when exposed to extremist material online. In considering psychiatric and legal issues, we then make recommendations by examining two notorious Canadian cases. Both individuals were reported to have ASD and received life sentences as a result of committing mass murder, with one individual targeting women, and the other targeting the Muslim population.

Sex differences in the flexibility of dynamic network reconfiguration of autism spectrum disorder based on multilayer network.

Dynamic network reconfiguration alterations in the autism spectrum disorder (ASD) brain have been frequently reported. However, since the prevalence of ASD in males is approximately 3.8 times higher than that in females, and previous studies of dynamic network reconfiguration of ASD have predominantly used male samples, it is unclear whether sex differences exist in dynamic network reconfiguration in ASD. This study used resting-state functional magnetic resonance imaging data from the Autism Brain Imaging Data Exchange database, which included balanced samples of 64 males and 64 females with ASD, along with 64 demographically-matched typically developing control (TC) males and 64 TC females. The multilayer network analysis was used to explore the flexibility of dynamic network reconfiguration. The two-way analysis of variance was further performed to examine the sex-related changes in ASD in flexibility of dynamic network reconfiguration. A diagnosis-by-sex interaction effect was identified in the cingulo-opercular network (CON), central executive network (CEN), salience network (SN), and subcortical network (SUB). Compared with TC females, females with ASD showed lower flexibility in CON, CEN, SN, and SUB. The flexibility of CEN and SUB in males with ASD was higher than that in females with ASD. In addition, the flexibility of CON, CEN, SN, and SUB predicted the severity of social communication impairments and stereotyped behaviors and restricted interests only in females with ASD. These findings highlight significant sex differences in the flexibility of dynamic network reconfiguration in ASD and emphasize the importance of further study of sex differences in future ASD research.

Selective deletion of Tsc1 from mouse cerebellar Purkinje neurons drives sex-specific behavioral impairments linked to autism.

There is a striking sex bias in the prevalence and severity of autism spectrum disorder (ASD) with 80% of diagnoses occurring in males. Because the molecular etiology of ASD is likely combinatorial, including interactions across multiple genetic and environmental factors, it is difficult to investigate the physiological mechanisms driving sex-specific differences. Loss of function mutations in TSC1 result in dysregulated mTORC1 signaling and underlie a multi-system disorder known as tuberous sclerosis (TSC). Interestingly, more than 50% of individuals diagnosed with TSC are also diagnosed with ASD, making TSC mutations one of the most prevalent monogenic causes of ASD. Mice harboring targeted deletion of Tsc1 selectively in cerebellar Purkinje neurons, referred to here as Tsc1 mut/mut , have multiple ASD-linked behavioral impairments, including deficits in social interactions, motor coordination, and vocalizations. However, these ASD-linked behavioral deficits have only been investigated using male Tsc1 mut/mut animals. Here, we used cohorts of male and female Tsc1 mut/mut animals to determine if behavioral impairments, previously identified in this model, are similar across sex. Specifically, we measured balance and motor coordination and social interaction behaviors in two age groups across sex. W e determined balance and motor coordination deficits are similar in male and female Tsc1 mut/mut mice, and that deficits in the firing of Tsc1 mut/mut Purkinje neurons located in the cerebellar vermis are also similar across sex. However, impairments in social approach behavior were found to be significantly more severe in Tsc1 mut/mut males compared to females. These results indicate the selective deletion of Tsc1 in Purkinje neurons differentially impairs cerebellar circuits based on sex.

TAAR1 and 5-HT1B receptor agonists attenuate autism-like irritability and aggression in rats prenatally exposed to valproic acid

Despite the rising prevalence of autism spectrum disorder (ASD), there remains a significant unmet need for pharmacotherapies addressing its core and associative symptoms. While some atypical antipsychotics have been approved for managing associated irritability and aggression, their use is constrained by substantial side effects. This study aimed firstly to develop behavioral measures to explore frustration, irritability and aggression phenotypes in the rat prenatal valproic acid (VPA) model of ASD. Additionally, we investigated the potential of two novel mechanisms, 5-HT1B and TAAR1 agonism, to alleviate these behaviors. Male offspring exposed to prenatal VPA were trained to achieve stable performance on a cued operant task, followed by pharmacological assessment in an operant frustration test, bottle brush test and resident intruder test. VPA exposed rats demonstrated behaviors indicative of frustration and irritability, as well as increased aggression compared to controls. The irritability-like behavior and aggression were further exacerbated in animals previously experiencing a frustrative event during the operant test. Single administration of the 5-HT1B agonist CP-94253 or TAAR1 agonist RO5263397 attenuated the frustration-like behavior compared to vehicle. Additionally, both agonists reduced irritability-like behavior under both normal and frustrative conditions. While CP-94253 reduced aggression in the resident intruder test under both conditions, RO5263397 only produced effects in rats that previously experienced a frustrative event. Our study describes previously uncharacterized phenotypes of frustration, irritability, and aggression in the rat prenatal VPA model of ASD. Administration of selective TAAR1 or 5-HT1B receptor agonists alleviated these deficits, warranting further exploration of both targets in ASD treatment.

AOP-based framework for predicting the joint action mode of di-(2-ethylhexyl) phthalate and bisphenol A co-exposure on autism spectrum disorder

Autism spectrum disorder (ASD), also known as autism, is a common, highly hereditary and heterogeneous neurodevelopmental disorder. The global prevalence of ASD among children continues to rise significantly, which is partially attributed to environmental pollution. It has been reported that pre- or post-natal exposure to di-(2-ethylhexyl) phthalate (DEHP) or bisphenol A (BPA), two prevalent environmental endocrine disruptors, increases the risk of ASD in offspring. Yet, the joint action mode linking DEHP and BPA with ASD is incompletely understood. This study aims to unravel the joint action mode of DEHP and BPA co-exposure on the development of ASD. An adverse outcome pathway (AOP) framework was employed to integrate data from multiple public database and construct chemical-gene-phenotype-disease networks (CGPDN) for DEHP- and BPA-related ASD. Topological analysis and comprehensive literature exploration of the CGPDN were performed to build the AOP. By analysis of shared key events (KEs) or phenotypes within the AOP or the CGPDN, we uncovered two AOPs, decreased N-methyl-D-aspartate receptor (NMDAR) and estrogen antagonism that were likely linked to ASD, both with moderate confidence. Our analysis further predicted that the joint action mode of DEHP and BPA related ASD was possibly an additive or synergistic action. Thus, we propose that the co-exposure to BPA and DEHP perhaps additively or synergistically increases the risk of ASD.

An ecological study shows increased prevalence of autism spectrum disorder in children living in a heavily polluted area

The burden of autism spectrum disorder (ASD) is increasing worldwide with genetic, epigenetic, and environmental factors being possibly responsible for the observed epidemiological figures. In the setting of environmental exposure, the city of Taranto, in Southern Italy, represents an interesting case study as it hosts well inside the city one of the biggest steel plants in Europe. This is a cross-sectional ecological study carried out in the year 2020 in the province of Taranto designed to estimate the burden of ASD in the municipalities of Taranto and Statte, classified as high environmental risk areas (Contaminated Site of National Interest—SIN), compared to the other 27 municipalities of the same province. Differences have been evaluated using the Chi Square Test. Children aged 6–11 years identified in SIN municipalities had a statistically significant higher prevalence of ASD than children of other municipalities (9.58 vs. 6.66/1000 respectively, p = 0.002). No statistically significant difference was observed for the 12–18 years group (3.41 vs. 2.54/1000, p = 0.12). The findings observed in this study are suggestive of the association between urban residential proximity to industrial facilities emitting air pollutants and higher ASD prevalence.

Social adaptation assistance for children with autism spectrum disorders in Kazakhstan

This study investigates the provision and effectiveness of social adaptation assistance for children with Autism Spectrum Disorder (ASD) in Almaty, Kazakhstan, with the aim of mapping available services, assessing their accessibility and impact, and identifying cultural and societal factors influencing ASD support. Employing a mixed-methods approach, the research combines a systematic literature review and a survey of 20 families with ASD-affected children aged between 4 and 16 years. The literature review focused on articles published from 2010 to 2022, exploring the prevalence of ASD and the extent of support services in Kazakhstan. Results indicate that while state-run educational programs are the most accessed form of assistance, challenges persist in terms of individualized attention and resource sufficiency. Independent and international initiatives are valued for their personalized approach but face limitations in capacity and reach. The study concludes that despite the growing awareness of ASD in Almaty, there is a critical need for comprehensive, culturally sensitive strategies that enhance the social adaptation and integration of children with ASD into society.

DNA Methylation in Autism Spectrum Disorders: Biomarker or Pharmacological Target?

Autism spectrum disorder (ASD) is a group of heterogeneous neurodevelopmental disabilities with persistent impairments in cognition, communication, and social behavior. Although environmental factors play a role in ASD etiopathogenesis, a growing body of evidence indicates that ASD is highly inherited. In the last two decades, the dramatic rise in the prevalence of ASD has interested researchers to explore the etiologic role of epigenetic marking and incredibly abnormal DNA methylation. This review aimed to explain the current understanding of the association between changes in DNA methylation signatures and ASD in patients or animal models. We reviewed studies reporting alterations in DNA methylation at specific genes as well as epigenome-wide association studies (EWASs). Finally, we hypothesized that specific changes in DNA methylation patterns could be considered a potential biomarker for ASD diagnosis and prognosis and even a target for pharmacological intervention.

Incidence of Nonsynostotic Plagiocephaly and Developmental Disorders.

This is the first population-based study quantifying the incidence of nonsynostotic positional plagiocephaly and/or brachycephaly (PPB) in infancy and its association with developmental disorders. To report the incidence of PPB before age 1 year, the incidence of craniosynostosis, and the percentage of children with PPB diagnosed with a developmental disorder by age 7 years. This was a retrospective, population-based cohort study of children in the Rochester Epidemiology Project (REP) born in Olmsted County, Minnesota, from January 1, 2008, through December 31, 2012, with follow-up through age 7 years. Data were analyzed from March 2021 to April 2024. Physical examination detecting cranial deformity. The primary outcome was the incidence of PPB. Secondary outcomes were the incidence of craniosynostosis and the percentage of children with PPB diagnosed with a developmental disorder by age 7 years. Of 9909 infants (5084 [51.3%] male; 9205 [92.9%] born at term and 704 [7.1%] born preterm) included in the study, 575 had PPB, for a PPB incidence of 5.8% (95% CI, 5.3%-6.3%). The incidence of PPB was 5.3% (95% CI, 4.8%-5.8%) in term infants vs 11.8% (95% CI, 9.4%-14.6%) in preterm infants. The incidence of craniosynostosis was 0.16% (95% CI, 0.09%-0.26%). A developmental disorder was known or suspected in 4.2% (95% CI, 2.7%-6.2%) of infants at the time of PPB diagnosis; among 402 infants with PPB and follow-up through age 7 years, 30 (7.5%; 95% CI, 5.0%-10.7%) had a confirmed developmental disorder by 7 years of age. The prevalence of autism spectrum disorder (ASD) in children with a history of PPB who were followed up to age 7 years was 2.2% (9 of 402 children). This study found that only a small percentage of the infants had positional head deformity significant enough to be documented and/or referred for subspecialty evaluation, and only a small subset of these children went on to have a developmental disorder in childhood. This information is helpful for counseling families about their child's developmental risk at time of PPB diagnosis.

A DNN-based diagnosis on autism spectrum disorder in children

The prevalence of autism spectrum disorder (ASD) witnesses a sharp increasing in recent years, and early diagnosis and intervention of ASD are critically needed. This study explored the efficacy of Deep Neural Networks (DNN) in diagnosing ASD among children aged 0 to 10. Utilizing the latest dataset derived from the ASDTests mobile application, which encompasses behavioral characteristics of over 2,000 children, we implemented a DNN model to capture complex non-linear patterns indicative of ASD. The results of comparative analysis with traditional machine learning models revealed DNN's superior accuracy in predicting ASD, indicating that the DNN achieved a significant improvement in identifying minority classes post-imbalance learning treatment. The promising results, including the 99.55% accuracy rate, paved the way for future investigations into integrating DNN with multimodal data analysis and other advanced algorithms to enhance early diagnostic processes and intervention strategies for ASD.

Mate selection and current trends in the prevalence of autism

BackgroundAccording to the most recent U.S. CDC surveillance data, the rise in prevalence of childhood autism spectrum disorder among minority children has begun to outpace that of non-Hispanic white children. Since prior research has identified possible differences in the extent of mate selection for autistic traits across families of different ethnicity, this study examined variation in autism related traits in contemporaneous, epidemiologically ascertained samples of spousal pairs representing Hispanic and non-Hispanic white populations. The purpose was to determine whether discrepancies by ethnicity could contribute to differential increases in prevalence in the current generation of young children.MethodsBirth records were used to identify all twin pairs born between 2011 and 2013 in California and Missouri. Families were selected at random from pools of English-speaking Hispanic families in California and Non-Hispanic White families in Missouri. Autistic trait data of parents was obtained using the Adult Report Form of the Social Responsiveness Scale (SRS-2).ResultsWe did not identify a statistically significant difference in the degree of mate selection for autism related traits between Hispanic and non-Hispanic white spousal pairs. However, the degree of spousal correlation observed in this recent cohort was pronounced (on the order of ICC 0.45) and exceeded that typically reported in prior research (on the order of 0.30), surpassing also widely reported estimates for sibling correlation (also on the order of 0.30).LimitationsThe sample did not allow for a direct appraisal of change in the magnitude of spousal correlation over time and the ascertainments of trait burden were derived from spouse report.ConclusionAcross two epidemiologically ascertained samples of spousal pairs representing Hispanic and non-Hispanic white families across two U.S. states (respectively, California and Missouri), the extent of autism-related trait co-variation for parents of the current generation of young children is substantial and exceeds correlations typically observed for siblings. Given the heritability of these traits and their relation to autism risk, societal trends in the degree of mate selection for these traits should be considered as possible contributors to subtle increases in the incidence of autism over time and across generations.

Autism spectrum disorder in young patients with congenital central hypoventilation syndrome: role of the autonomic nervous system dysfunction

BackgroundCongenital central hypoventilation syndrome (CCHS) is a rare condition characterized by alveolar hypoventilation and autonomic nervous system (ANS) dysfunction requiring long-term ventilation. CCHS could constitute a risk factor of autism spectrum disorder (ASD) due to birth injury related to respiratory failure, which remains to be determined. ANS dysfunction has also been described in ASD and there are indications for altered contribution of ANS-central nervous system interaction in processing of social information; thus, CCHS could be a risk factor for ASD based on pathophysiological background also. Our study aimed to determine the prevalence of ASD among CCHS patients, identify risk factors, and explore the relationship between the ANS, evaluated by heart rate variability indices, and adaptative functioning.ResultsOur retrospective study, based on the analysis of records of a French national center of patients with CCHS under 20 years of age, determined that the prevalence of ASD (diagnosed by a psychiatrist, following the criteria of DSM-4 or DSM-5) was 6/69 patients, 8.7% (95% confidence interval: 3.3–18.0%). In a case (CCHS with ASD, n = 6) – control (CCHS without ASD, n = 12) study with matching on sex, longer neonatal hospitalization stay and glycemic dysfunction were associated with ASD. Adaptative functioning was assessed using Vineland Adaptative behavioral scales (VABS) and heart rate variability indices (including daytime RMSSD as an index of parasympathetic modulation) were obtained from ECG Holter performed the same day. In 19 young subjects with CCHS who had both ECG Holter and VABS, significant positive correlations were observed between RMSSD and three of four sub-domains of the VABS (communication: R = 0.50, p = 0.028; daily living skills: R = 0.60, p = 0.006; socialization: R = 0.52, p = 0.021).ConclusionOur study suggests a high prevalence of ASD in patients with CCHS. Glycemic dysfunction and longer initial hospitalization stays were associated with ASD development. A defect in parasympathetic modulation was associated with worse adaptative functioning.

Emerging Treatments and Therapies for Autism Spectrum Disorder: A Narrative Review.

The prevalence of autism spectrum disorder (ASD) has increased over the last decade. In this regard, many emerging therapies have been described as ASD therapies. Although ASD does not have a cure, there are several management options available that can help reduce symptom severity. ASD is highly variable and, therefore, standard treatment protocols and studies are challenging to perform. Many of these therapies also address comorbidities for which patients with ASD have an increased risk. These concurrent diagnoses can include psychiatric and neurological disorders, including attention deficit and hyperactivity disorder, anxiety disorders, and epilepsy, as well as gastrointestinal symptoms such as chronic constipation and diarrhea. Both the extensive list of ASD-associated disorders and adverse effects from commonly prescribed medications for patients with ASD can impact presenting symptomatology. It is important to keep these potential interactions in mind when considering additional drug treatments or complementary therapies. This review addresses current literature involving novel pharmacological treatments such as oxytocin, bumetanide, acetylcholinesterase inhibitors, and memantine. It also discusses additional therapies such as diet intervention, acupuncture, music therapy, melatonin, and the use of technology to aid education. Notably, several of these therapies require more long-term research to determine efficacy in specific ASD groups within this patient population.

THE GLOBAL PREVALENCE AND DIAGNOSIS OF AUTISM SPECTRUM DISORDER (ASD) AMONG YOUNG CHILDREN

Autism Spectrum Disorder (ASD) refers to a group of developmental disorders. Although the global prevalence of ASD is reported to be between 3-6 children per 1000, there is difficulty in comparing the prevalence of ASD across countries because of the variation in methodology, age group of population and the sample size studied. The prevalence of ASD shows an increasing trend and factors attributing to the rise in prevalence include the increase in awareness on the signs and symptoms of ASD, the increase in access to services, the changes in the definition of autism over time and the broadening of the diagnostic criteria. Among the administrative factors also linked to the increase in prevalence were changed in reporting practices and availability of records. Before1990’s diagnosis of ASD was more often after the entrance to the school. Currently, there are diagnostic tools available and the diagnosis can be made among toddlers. However, for those on the milder end of the spectrum with average or above-average language and cognitive abilities, the diagnosis is still made after school entry. Early detection, diagnosis, and intervention are important in promoting better long-term outcomes and as such screening programs need to be in place. Sustainability of the program requires training of primary care providers, the use of specially designed tools for screening and protocols for referral, and a multidisciplinary diagnostic team. This paper shares the Malaysian experience in implementing a screening program since 2011 and the outcomes of the screening program for ASD in primary care.

Breaking Barriers: Enhancing Support for Autistic Students Through Individual Education Programs

The prevalence of Autism Spectrum Disorders (ASD) underscored the importance of tailoring educational interventions to accommodate the diverse needs of autistic students in Nigeria. This study investigated the effectiveness of individual educational programs in meeting the needs of autistic students in Nigeria. The study surveyed autistic children, teachers, and parents in special schools in Ikeja, Apapa, and Kosofe Local Government Areas of Lagos State. It used a mixed-methods approach to evaluate the effectiveness of Individual Education Programs (IEPs) in addressing the unique needs of autistic students in mainstream educational settings. The study analyzed academic performance metrics and social skills proficiency in autistic students. It also explored the experiences of teachers, parents, and autistic students through interviews and focus groups. Despite challenges like lack of resources and collaboration issues, teachers shared success stories and strategies. Parents praised positive efforts between home and school, while autistic students expressed improved learning experiences. The synthesis of quantitative and qualitative data provided a holistic evaluation of IEPs' effectiveness in promoting positive outcomes for autistic students. The findings contribute to the discourse on inclusive education, informing practices to refine IEP design and implementation. The study emphasizes providing meaningful educational support tailored to the diverse needs of autistic students in mainstream settings.

Prevalence of Autism risk among children undergoing regular Psychophysical Development Screening in Kazakhstan

BackgroundInformation about the situation with autism in Kazakhstan is extremely limited due to the lack of research on autism in both Kazakhstan and Central Asia. The prevalence of autism spectrum disorder risk among young children during routine screening was assessed using the M-CHAT-R/F tool. MethodsThis study took place in the offices of pediatric neurologists and family doctors in three primary healthcare organizations in the Karaganda, Kazakhstan. The researchers offered participation in the study and M-CHAT-R checklist completion during visits by parents and children to pediatric neurologists and family doctors for the purpose of screening for psychophysical development. Linear regression analysis was used to determine risk factors for the development of autism spectrum disorder. ResultsThe results of an analysis of 526 study participants showed the prevalence of high-risk autism spectrum disorders to be 27.4 %. Factors associated with a high risk of autism spectrum disorder in this study were child age, gender, parental age, and a diagnosis of developmental disorder. ConclusionsThe use of specific tools to screen for developmental disorders by primary care organizations is recommended. Primary care providers have regular contact with children before they reach school age and can provide family-centered, comprehensive, and coordinated care, including more comprehensive medical assessments.

Evaluation of a program of social intervention for adolescents with autism spectrum disorders (PROSEAR)

Purpose The prevalence of autism spectrum disorders (ASD) surpasses 2% in some regions. However, there is a lack of manualized programs targeting the social skills of adolescents with these disorders, particularly in the Spanish language context. This study aims to introduce PROSEAR, an innovative social skills program for adolescents with ASD implemented in a Day Hospital setting. Design/methodology/approach The evaluation used the Strengths and Difficulties Questionnaire (SDQ) and the Social Skills Scale (EHS) as measures, administering pre- and postintervention tests for each patient. Findings SDQ exhibited the most significant improvement in the domain of peer problems. In terms of EHS, it demonstrated beneficial effects across all evaluated domains, with statistically significant improvements observed specifically in the expression of anger or disagreement. Limitations include a small sample size and lack of a randomized control group. Originality/value The outcomes align with existing literature supporting the intervention as positive in clinical practice. Overall, the PROSEAR intervention shows promise for enhancing social skills in adolescents with ASD. Further research is needed to improve therapeutic approaches for this population.
