ABSTRACT

La falta de información sobre el uso de la tecnología en niños con trastorno del espectro autista (TEA) de diferentes perfiles puede dificultar que docentes y alumnos se estén beneficiando del apoyo tecnológico más eficaz y ajustado a sus necesidades. El objetivo de esta revisión fue analizar y sintetizar la evidencia científica sobre la eficacia de los recursos tecnológicos en la mejora de la comprensión emocional de estudiantes con TEA con perfiles de alto y bajo funcionamiento. Para ello se realizó una revisión sistemática de las publicaciones científicas indexadas en algunas de las bases de datos de mayor relevancia siguiendo los criterios establecidos en la declaración PRISMA. En total se analizaron 38 artículos que cumplieron con los criterios de inclusión preestablecidos. Los resultados muestran la importancia de diseñar sistemas versátiles que puedan personalizarse y adaptarse en tiempo real y en contextos naturales con un enfoque claramente inclusivo. Pero también sugieren que la tecnología puede no ser una herramienta de intervención complementaria adecuada para todos los niños con TEA. Lo que subraya la necesidad de ensayos adicionales bien controlados sobre las características que permitan identificar qué estudiantes podrían o no beneficiarse de diferentes modalidades de tecnología.

The lack of information on the use of technology in children with autism spectrum disorder (ASD) of different profiles can make it difficult for teachers and students to benefit from the most effective technology support tailored to their needs. The aim of this review was to analyze and synthesize scientific evidence on the effectiveness of technological resources in improving the emotional understanding of students with high and low functioning ASD profiles. A systematic review of the scientific publications indexed in some of the most relevant databases was carried out following the criteria established in the PRISMA declaration. A total of 38 articles that met the pre-established inclusion criteria were analyzed. The results show the importance of designing versatile systems that can be customized and adapted in real time and in natural contexts with a clearly inclusive approach. But they also suggest that technology may not be an appropriate complementary intervention tool for all children with ASD. This underlines the need for additional well-controlled tests on the characteristics that would allow identifying which students might or might not benefit from different technology modalities.

ABSTRACT

Parenting a child on the autism spectrum presents particular challenges that can lead to increased stress, anxiety, and depression among family members. Therefore, we aimed to investigate the prevalence of mental disorders in first-degree relatives of individuals on the autism spectrum. This article adheres to the Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols (PRISMA-P) guidelines, including studies indexed in PubMed/Medline, Embase, PsycINFO, Biblioteca Virtual em Saúde (BVS), and SciELO. Nineteen articles met eligibility criteria for the systematic review. Using a random-effects model (N = 93,876), we found a pooled prevalence of affective disorders of 13% in mothers of people on the autism spectrum (95% CI 7-21%; I2 = 99%, p < 0.01). Additionally, another random-effects model pointed out that first-degree relatives of people on the autism spectrum (N = 93,263) were more likely to present affective disorders than relatives of people with neurotypical development (N = 152,455) (pooled OR: 2.17; 95% CI 1.81-2.61). Careful assessment for mental disorders in parents and siblings of individuals on the autism spectrum is crucial to ensure appropriate treatment for these family members. This approach can also contribute to optimizing care for the individuals on the autism spectrum.

ABSTRACT

PURPOSE: Translation of research is requisite for speech-language pathologists; however, barriers have been reported. This review aimed to identify the extant literature published on communication for autistic children, and examine the replicability and translatability of communication interventions for speech-language pathologists providing services to children with autism. METHOD: A scoping review was conducted using a six-stage protocol. Following initial database searching and screening, data were extracted from included studies for demographic characteristics and Template for Intervention Description and Replication (TIDieR) checklist elements. Stakeholder consultation interviews with 13 speech-language pathologists who work with autistic children were also undertaken. RESULT: The database search revealed 4719 studies on the topic of communication in autistic children, of which 762 were communication intervention studies. Of these included intervention studies, 30% were considered replicable according to the TIDieR checklist. Stakeholder consultation revealed that poorly described intervention studies hindered translation efforts. CONCLUSION: The vast amount of autism communication intervention literature and the variable quality of intervention description reporting are barriers to accessing high quality literature for translation to practice. Improved reporting of intervention descriptions in autism communication intervention studies would support research translation into clinical settings.

ABSTRACT

Implicit learning plays an important role in the acquisition of various skills that are often deficient in individuals with autism spectrum disorder (ASD). The present study examines the implicit learning ability of children and adolescents with ASD, by comparing it to that of a typical group of peers, using the Artificial Grammar Learning (AGL) task. Additionally, this study investigates whether the above ability is associated with individual characteristics, namely, intelligence quotient (IQ), ASD symptoms severity, and individual perception style (global/holistic or local/focused). The sample consisted of 20 individuals with mild to relatively severe ASD symptoms and 20 age- and gender-matched typically developing individuals (TD). The unconscious (implicit) nature of learning was assessed via a subjective measure, the "no loss gambling" method, which allows an unbiased evaluation of the confidence accompanying each judgement. The results provided evidence of implicit learning, which was preserved in the ASD group, although reduced relative to the typical group. Multiple linear regressions with interaction terms between Group and participants' scores on the Wechsler Abbreviated Scale of Intelligence (WASI), the Childhood Autism Rating Scale (CARS), and performance on a Navon-type task examined whether the possible relationships between each of the above scores and AGL and implicit learning differ in the two groups. Implicit learning was not significantly associated with IQ, ASD symptoms severity or individual perception style (except for perception style in terms of RTs for the TD group). These results confirm and extend earlier findings supporting the resilience of implicit learning to individual differences.

ABSTRACT

OBJECTIVE: Early life seizures (ELS) are commonly associated with autism spectrum disorder (ASD); however, the exact role of ELS in the pathology is unknown. Prior studies have demonstrated social deficits, a core feature of ASD, following ELS; consequently, alterations in sensory modalities may contribute to the overall social deficits. Considering the speculated contribution of sensory deficit to social communication, we examined the developmental consequences of early postnatal kainic acid (KA)-induced seizures on olfactory preference and neural markers in the olfactory bulb in both male and female Sprague Dawley rats. METHODS: KA-induced seizures or saline was administered. Rats were then exposed to a series of biologically relevant scents including male scent, female scent, nest scent, and phenylethylamine during the juvenile period and again during adulthood. Alterations in sensory modalities were expected to be expressed via abnormal preference for certain scents and/or production of abnormal ultrasonic vocalizations in response to scents. The olfactory bulbs were also assessed for the biologically relevant markers glial fibrillary acidic protein (GFAP) and calcium/calmodulin-dependent protein kinase II (CAMKII). RESULTS: Our findings resulted in no significant differences in olfactory preference following ELS for juveniles or adults compared to controls. Similarly, there were no differences in GFAP expression or the ratio of phosphorylated CAMKII to CAMKII in either olfactory bulb. Interestingly, despite a lack of treatment differences, different scents were shown to elicit different responses in juvenile rats, yet these differences subsided in adulthood. SIGNIFICANCE: Overall, the results of this study suggest that olfaction does not contribute to socialization deficit following ELS within the KA model.

ABSTRACT

OBJECTIVES: Mental chronometry is the scientific study of cognitive processing speed measured by reaction time (RT), which is the elapsed time between the onset of a stimulus and an individual's response. This study aims at measuring the RT among young children with autism spectrum disorders (ASD) and comparing it with normal (typically developing) children. METHODS: 60 ASD children were selected from different ASD centers, and 60 normal children were selected from different kindergartens for participation in this study. Participants were aged 3-6 years old. The RT was measured using the Fitlight trainer device. The findings were statistically evaluated using independent t-tests and ANOVA tests. RESULT: Significant differences (p < 0.0001) were found between both groups in all tasks, and ASD children demonstrated slower RT compared to the normal group. The RT measured through three senses (visual, auditory, and touch) for ASD and normal were 3.64 ± 2.16, 13.19 ± 2.41(trial), 1835.23 ± 757.95, 697.12 ± 87.83 (second), and 1550.89 ± 499.76, 752.67 ± 124.02 (second) respectively. CONCLUSION: The evaluated RT showed significant impairment in RT among ASD in comparison to normal children and this was true for the three senses. The Fitlight trainer could be used to assess RT and stimulus-response among ASD children in various cognitive tasks. Similar studies, involving larger samples from different areas and involving other sense organs, are indicated to confirm the results.

ABSTRACT

Transitive inference (TI) has a long history in the study of human development. There have, however, few pediatric studies that report clinical diagnoses have tested trial-and-error TI learning, in which participants infer item relations, rather than evaluate them explicitly from verbal descriptions. Children aged 8-10 underwent a battery of clinical assessments and received a range of diagnoses, potentially including autism spectrum disorder (ASD), attention-deficit hyperactive disorder (ADHD), anxiety disorders (AD), specific learning disorders (SLD), and/or communication disorders (CD). Participants also performed a trial-and-error learning task that tested for TI. Response accuracy and reaction time were assessed using a statistical model that controlled for diagnostic comorbidity at the group level. Participants in all diagnostic categories showed evidence of TI. However, a model comparison analysis suggested that those diagnosed with ASD succeeded in a qualitatively different way, responding more slowly to each choice and improving faster across trials than their non-ASD counterparts. Additionally, TI performance was not associated with IQ. Overall, our data suggest that superficially similar performance levels between ASD and non-ASD participants may have resulted from a difference in the speed-accuracy tradeoff made by each group. Our work provides a preliminary profile of the impact of various clinical diagnoses on TI performance in young children. Of these, an ASD diagnosis resulted in the largest difference in task strategy.

ABSTRACT

INTRODUCTION: Very preterm birth is an important risk factor for autism spectrum disorder (ASD). The aim of this study is the early detection of ASD risk, using a follow-up protocol, in children weighing less than 1500 g at birth or born before 32 weeks of gestation. METHODS: This is a prospective longitudinal study in which a total of 133 very premature babies were monitored to the age of 2 years with the M-CHAT autism screening test and, in the event of a positive result, the Autism Diagnostic Observation Schedule (ADOS-2). RESULTS: 53 cases (4 out of 10) screened positive, and the rest negative. Among the positives, the ADOS-2 was administered in 50 cases, of which 24 scored above the ASD cutoff point. The average age of detection was 25.39 months. The results suggest an estimated prevalence of ASD in the very premature population of 18.46 %. CONCLUSIONS: The application of the follow-up protocol in the very premature population is effective for early detection of ASD.

ABSTRACT

Evidence suggests different mismatch negativity (MMN) and P3a responses in individuals with autism spectrum disorder (ASD). Since unaffected siblings shared aberrant neurocognition and brain connectivity with ASD probands, this study investigated MMN and P3a responses in unaffected siblings and explored its neurocognitive implications and effects modifiers. We assessed 43 unaffected siblings of ASD probands and 64 non-autistic comparisons (NTC) using MMN and P3a on both frequency and duration oddball paradigms. The amplitude and latency of MMN and P3a were compared between unaffected siblings and NTC, and validated in 67 ASD probands. In addition, the neurocognitive correlates of MMN and P3a parameters were explored in attention performance, spatial working memory (SWM), and visual research via the tasks of the Conners' Continuous Performance Test and the Cambridge Neuropsychological Test Automated Battery. Compared to NTC, unaffected siblings and ASD probands presented a shorter MMN latency. The P3a amplitude of the duration paradigm (dP3a) was correlated with fewer commission errors, fewer SWM total errors, higher detectability, and more correct responses on visual search tasks. In addition, the dP3a amplitude significantly interacted with sibship, age, and full-scale IQ to predict attention performance, SWM total errors, and total correct response on visual search. Findings suggest that unaffected siblings of ASD may have earlier brain responses upon novelty discrimination. P3a amplitude may correlate with better neurocognitive performance, but the effect was moderated by sibship, age, and intelligence.

ABSTRACT

Grandparents play different roles in families of children and adolescents on the autism spectrum. They are frequently engaged in caregiving tasks with the person on the autism spectrum, providing emotional and instrumental support to the family. However, despite their frequent involvement and the importance of their role in the family, there are few studies that address the experiences of these grandparents, particularly in the Spanish and southern Europe context. This study explores the impact and needs of having a grandchild on the autism spectrum and the resources that grandparents have and use to face the difficulties that arise. A semi-structured interview was carried out with 17 grandparents of children and adolescents on the autism spectrum. We conducted a coding reliability thematic analysis of the impact and used a quantitative content analysis of grandparents' needs and resources. Results indicated three main aspects related to the impact: personal growth, wanting to help and not being able to, and suffering at three levels: for themselves, their sons and daughters, and grandchildren. Grandparents perceived needs in four contexts: their own needs, the needs of the nuclear family, the needs of the person on the autism spectrum, and the needs of society. The most frequent needs were informational and management of behavioral difficulties. In the resources, the most frequently used strategies were religious beliefs and informal support seeking. It is essential to address the quality of parents-grandparents' relationships, and include grandparents in intervention programmes, as a way of addressing grandparents' needs.

ABSTRACT

PURPOSE: To explore actions taken by health care professionals during a procedure with a child with autism spectrum disorder DESIGN AND METHOD: Critical incident technique was used, which is a technique with a qualitative descriptive retrospective design, to capture situations experienced by health care professionals during a procedure in an anaesthesia or radiology department. Health care professionals from anaesthesia and radiology departments (n = 20) were interviewed about situations affecting the procedure. RESULTS: The findings revealed a broad range of actions (n = 205) taken by the health care professionals during a procedure with a child with autism spectrum disorder. The analysis resulted in two main areas: Finding a way to facilitate a procedure in a high technology environment and Creating a trustful relationship with a child with autism spectrum disorder. The most common action in the first area, was to adjust routines. In the second area the most common action was to take one step at a time and not force or rush the child during the procedure. PRACTICE IMPLICATIONS: The health care professionals used a broad range of different actions to facilitate a procedure in the high technology environment for a child with ASD, which indicates the need for a flexible approach. The actions taken included both adjustments to the environment and enhancing interactions with the child.

ABSTRACT

Sex heterogeneity has been frequently reported in autism spectrum disorders (ASD) and has been linked to static differences in brain function. However, given the complexity of ASD and diagnosis-by-sex interactions, dynamic characteristics of brain activity and functional connectivity may provide important information for distinguishing ASD phenotypes between females and males. The aim of this study was to explore sex heterogeneity of functional networks in the ASD brain from a dynamic perspective. Resting-state functional magnetic resonance imaging data from the Autism Brain Imaging Data Exchange database were analyzed in 128 ASD subjects (64 males/64 females) and 128 typically developing control (TC) subjects (64 males/64 females). A sliding-window approach was adopted for the estimation of dynamic amplitude of low-frequency fluctuation (dALFF) and dynamic functional connectivity (dFC) to characterize time-varying brain activity and functional connectivity respectively. We then examined the sex-related changes in ASD using two-way analysis of variance. Significant diagnosis-by-sex interaction effects were identified in the left anterior cingulate cortex/medial prefrontal cortex (ACC/mPFC) and left precuneus in the dALFF analysis. Furthermore, there were significant diagnosis-by-sex interaction effects of dFC variance between the left ACC/mPFC and right ACC, left postcentral gyrus, left precuneus, right middle temporal gyrus and left inferior frontal gyrus, triangular part. These findings reveal the sex heterogeneity in brain activity and functional connectivity in ASD from a dynamic perspective, and provide new evidence for further exploring sex heterogeneity in ASD.

ABSTRACT

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is often present in people with intellectual disability (ID) and autism. However, few ADHD measures have been developed specifically for individuals with these conditions. There is little literature exploring how well ADHD measures are performing at picking up specific symptoms at the item level. METHODS: Analyses were conducted on data from 122 children aged 7-15 years old with diagnoses of both ADHD and ID enrolled in the Hyperactivity and Special Educational Needs trial. Parents and teachers completed ratings of ADHD symptoms on the Aberrant Behavior Checklist (ABC) hyperactivity subscale and the revised Conners' Rating Scales hyperactivity scale and ADHD index. Cronbach's alpha was used to examine the reliability of these measures. Item response theory explores the performance of individual items. Multiple indicators, multiple causes models were used to test for measurement invariance by ID severity, co-occurring autism traits and child age. RESULTS: The reliability of parent and teacher reports of ADHD symptoms on the Conners' and ABC was acceptable across the range of ID. Item performance was generally good, and information was provided across the continuum of ADHD traits. Few items on either measure were non-invariant (i.e., item endorsement generally did not differ based on other child characteristics). When non-invariance was found, the effect was small. CONCLUSIONS: Both the parent-reported and teacher-reported versions of the Conners' hyperactivity scale and ADHD index and the ABC hyperactivity subscale appear to function well in the current sample of children with co-occurring ADHD and ID.

ABSTRACT

Oral folinic acid has shown potential to improve symptoms in children with autism spectrum disorder (ASD). However, randomized controlled trials (RCTs) are limited. This double-blind, placebo-controlled RCT aimed to compare changes in Childhood Autism Rating Scale (CARS) scores in children with ASD aged 2-10 years, among folinic acid (2 mg/kg/day, maximum of 50 mg/day) and placebo groups at 24 weeks, in comparison with baseline. Both the groups received standard care (ABA and sensory integration therapy). Secondary objectives included changes in behavioral problems measured by the Child Behavior Checklist (CBCL) and serum levels of anti-folate receptor autoantibodies and folic acid, correlated with changes in autism symptom severity. Out of the 40 participants recruited in each group, 39 and 38 participants completed the 24-week follow-up in the folinic acid and placebo groups, respectively. The change in CARS score was higher in the folinic acid group (3.6 ± 0.8) compared to the placebo group (2.4 ± 0.7, p < 0.001). Changes in CBCL total score and CBCL internalizing score were also better in the folinic acid group (19.7 ± 9.5 vs. 12.6 ± 8.4 and 15.4 ± 7.8 vs. 8.5 ± 5.7, p < 0.001 for both). High-titer anti-folate receptor autoantibodies were positive in 32/40 and 33/40 cases in the folinic acid and placebo groups, respectively (p = 0.78). In the placebo group, improvement in CARS score was comparable regardless of autoantibody status (p = 0.11), but in the folinic acid group, improvement was more pronounced in the high-titer autoantibody group (p = 0.03). No adverse reactions were reported in either group. CONCLUSIONS: Oral folinic acid supplementation is effective and safe in improving ASD symptoms, with more pronounced benefits in children with high titers of folate receptor autoantibodies. TRIAL REGISTRATION:  CTRI/2021/07/034901, dated 15-07-2021. WHAT IS KNOWN: • Folate receptor autoantibodies are more prevalent in children with autism spectrum disorder (ASD) compared to typically developing children. • Folate receptor autoantibodies play a significant role in the neuropathogenesis of autism spectrum disorder. WHAT IS NEW: • Add-on oral folinic acid supplementation is safe and effective in reducing the severity of symptoms in children with ASD. • The clinical benefits are more pronounced in children with high titers of folate receptor autoantibodies.

ABSTRACT

OBJECTIVE: The present study investigated whether autistic adults report different levels of mental imagery vividness than non-autistic adults, and, moreover, if autism is associated with aphantasia which is defined as a condition of reduced or absent voluntary imagery. DESIGN AND METHODS: Clinically diagnosed and self-identifying autistic participants were compared with non-autistic participants in their mental imagery vividness (vision, sound, smell, taste, touch, bodily sensation and emotional feeling) and autistic traits using an online survey (N = 121). RESULTS: The autistic group scored significantly lower than the non-autistic group on imagery vividness (d = -0.44), in addition to having a higher proportion of participants scoring at cut-off for aphantasia. Moreover, a similar difference was observed for the emotional feel (η2 = 0.11). CONCLUSION: The vividness of visual and emotional mental imagery was on average lower for autistic individuals, with a higher proportion presenting at cut-off to be considered an aphantasic.

ABSTRACT

Unlike other functional integration methods that examine the relationship and correlation between two channels, effective connection reports the direct effect of one channel on another and expresses their causal relationship. In this article, we investigate and classify electroencephalographic (EEG) signals based on effective connectivity. In this study, we leverage the Granger causality (GC) relationship, a method for measuring effective connectivity, to analyze EEG signals from both healthy individuals and those with autism. The EEG signals examined in this article were recorded during the presentation of abstract images. Given the nonstationary nature of EEG signals, a vector autoregression model has been employed to model the relationships between signals across different channels. GC is then used to quantify the influence of these channels on one another. Selecting regions of interest (ROI) is a critical step, as the quality of the time periods under consideration significantly impacts the outcomes of the connectivity analysis among the electrodes. By comparing these effects in the ROI and various areas, we have distinguished healthy subjects from those suffering from autism. Furthermore, through statistical analysis, we have compared the results between healthy individuals and those with autism. It has been observed that the causal relationship between these two hemispheres is significantly weaker in healthy individuals compared to those with autism.

ABSTRACT

Introduction: Over the past few decades, there has been growing concern about the concurrent trends of increasing Autism Spectrum Disorder (ASD) prevalence and declining sperm quality. These trends represent significant public health challenges that warrant thorough investigation of their underlying causes and implications. Objectives: The primary objectives of this study are to analyze trends in ASD prevalence and sperm quality parameters from 2000 to 2024, assess the statistical significance and effect size of these trends, explore potential correlations between ASD prevalence and sperm quality parameters, and identify significant predictors among sperm quality parameters that influence ASD prevalence. Methods: This study employed a longitudinal approach using multiple regression, time series analysis, ANOVA, Principal Component Analysis (PCA), hierarchical clustering, logistic regression, and cross-correlation analysis. Data on ASD prevalence were sourced from the CDC Autism and Developmental Disabilities Monitoring Network, while sperm quality data were collected from various published studies. Results: The findings reveal significant negative associations between ASD prevalence and sperm quality parameters such as sperm concentration and motility, suggesting that better sperm quality is linked to lower ASD rates. Conversely, parameters like sperm DNA fragmentation (SDF), volume of ejaculate, pH level, and semen viscosity show positive associations with ASD prevalence, indicating higher values in these parameters correlate with higher ASD rates. Conclusion: The study highlights the importance of maintaining reproductive health to potentially mitigate ASD risk and calls for further research to elucidate the underlying mechanisms driving these trends. These findings support the hypothesis that reproductive health factors play a crucial role in ASD etiology and suggest potential biological markers for assessing ASD risk.

ABSTRACT

BACKGROUND: Parental stress experienced in the context of caring for children with autism spectrum disorder (ASD) in preschool is significant and has been poorly studied; studies tend to focus on more advanced ages of children where parental symptomatology has become chronic. The current study sought to provide new empirical evidence on factors associated with parental stress. METHODS: An exhaustive search was conducted in four academic databases: CINAHL Complete, Medline Complete, Web of Science (WoS), and Scopus, limiting the articles to those published between 2017 and 2023. RESULTS: The sample obtained consisted of 24 selected articles, which were produced in 11 countries, and all were in English. In terms of content, the topics addressed were the manifestation of parental stress, factors of the child with ASD and their relationship with parental stress, factors of parents of children with ASD, family factors of parents of children with ASD, social factors of parents of children with ASD, parental stress and access to formal care services, and parental stress and specialized interventions. CONCLUSIONS: It is possible to affirm that research reports indicate that the general level of stress among parents of children with ASD is compared to their reference groups, both in relation to child-related stress and other stressors. The variables that affect parental stress exhibit a reciprocal influence among them, so interventions aimed at early childhood should incorporate both the children and their parental figures. This is in consideration of the impact that stress has on the mental health of parents, establishing that parents with better health have early access to support services during the early years of parenting, as well as in later years.


INTRODUCCIÓN: El estrés parental vivenciado en el contexto de cuidado de los niños con trastorno del espectro autistas en etapa preescolar es significativo y ha sido muy poco estudiado, las investigaciones tienden a focalizarse en edades de los niños más avanzada donde la sintomatología de los padres se ha cronificado. El objetivo de la presente investigación fue actualizar el corpus de evidencia empírica referida a los factores relacionados con el Estrés parental. MÉTODOS: Se realizó una búsqueda exhaustiva en cuatro bases de datos académicas: CINAHL Complete, Medline Complete, Web of Science (WoS) y Scopus, limitando los artículos publicados entre los años 2017 y 2023. RESULTADOS: La muestra obtenida fue de 24 artículos seleccionados, los cuales fueron producidos por 11 países todos de habla inglesa. En cuanto al contenido, los temas abordados son: La manifestación del estrés parental, factores del niño con TEA y su relación con el estrés parental, factores de los padres de los niños con TEA, factores familiares de los padres de los niños con TEA, factores sociales de los padres de los niños con TEA, estrés parental y acceso a los servicios formales de atención, y estrés parental e intervenciones especializadas. CONCLUSIONES: Es posible afirmar que las investigaciones reportan que el nivel general de estrés de los padres de niños con TEA es superior al de sus grupos de referencia, tanto en relación al estrés relacionado con el niño, como el que no. Las variables que afectan el estrés parental presentan una influencia recíproca entre éstas, por lo que las intervenciones dirigidas a la primera infancia deberían incorporar a los niños y a sus figuras parentales. Esto, en atención al impacto que el estrés presenta en la salud mental de los padres, estableciendo que los padres con mejor salud mental presentan mayor acceso temprano a los servicios de apoyo durante los primeros años de crianza, y en los años posteriores.

ABSTRACT

Background and aims: Autistic children can experience challenges in making and maintaining friendships, and middle childhood (ages 6-12) may be particularly challenging as social networks become more complex. However, a large proportion of research into these experiences is based on adult reports or focuses on the experiences of adolescents, meaning that the voices of younger children are absent. Due to the exclusion of younger children from research, we have a limited understanding of their first-hand experiences of their friendships and the support they receive, which has implications for friendship support and wellbeing. This study aimed to amplify the voices of younger autistic children to explore their first-hand experiences of friendships and highlight areas of social support which may be most beneficial to primary-aged autistic children. Methods: This study used novel creative methods to support interviews with 19 autistic primary school-aged children to explore their experiences of friendship. Parent-led interviews and scrapbooks supported the children in discussing the challenges and strengths of their friendships. Results: Children discussed the challenges and strengths of their friendships including the impact of social norms on the need to have friends and their support needs in this area of life. Children also discussed gaps in their current friendships and how they would like to see these filled. It was clear that not all children required or wanted neurotypical-style friendships, with many valuing companionship and gameplay over intimacy. Analysis highlighted the heterogeneity of autistic children's friendships, especially in relation to gender and age, calling for more tailored and individualized support. Conclusion and implications: Results from the current study show that autistic children can and do have successful friendships but that these friendships may differ from those of their non-autistic peers. The study further adds to the existing literature by showing that younger autistic children can be included in research by using differentiated, accessible and creative methods, and that they are able to voice their opinions on matters surrounding support. It also calls for a tailored approach to supporting autistic children in school and speaking with children to give them autonomy over the support they want to receive.
