Oculomotor characteristics, including accuracy, timing, and sensorimotor processing, are considered sensitive intermediate phenotypes for understanding the etiology of neurodevelopmental conditions, such as autism and ADHD. Oculomotor characteristics have predominantly been studied separately in autism and ADHD. Despite the high rates of co-occurrence between these conditions, only one study has investigated oculomotor processes among those with co-occurring autism + ADHD. Four hundred and five (n = 405; 226 males) Australian children and adolescents aged 4 to 18 years (M = 9.64 years; SD = 3.20 years) with ADHD (n = 64), autism (n = 66), autism + ADHD (n = 146), or neurotypical individuals (n = 129) were compared across four different oculomotor tasks: visually guided saccade, anti-saccade, sinusoidal pursuit and step-ramp pursuit. Confirmatory analyses were conducted using separate datasets acquired from the University of Nottingham UK (n = 17 autism, n = 22 ADHD, n = 32 autism + ADHD, n = 30 neurotypical) and University of Kansas USA (n = 29 autism, n = 41 neurotypical). Linear mixed effect models controlling for sex, age and family revealed that children and adolescents with autism + ADHD exhibited increased variability in the accuracy of the final saccadic eye position compared to neurotypical children and adolescents. Autistic children and adolescents demonstrated a greater number of catch-up saccades during step-ramp pursuit compared to neurotypical children and adolescents. These findings suggest that select differences in saccadic precision are unique to autistic individuals with co-occurring ADHD, indicating that measuring basic sensorimotor processes may be useful for parsing neurodevelopment and clinical heterogeneity in autism.

There are few validated remote tools that can be used to assess for autism and to capture subtle changes in children's social communication over time. Recently, user-centered design principles were applied to develop a parent-mediated remote assessment, the Reciprocal Imitation and Social Engagement Child Play Protocol (RISE CPP) to enable researchers to capture micro-level behaviors in children, while promoting useability for researchers and families, reducing caregiver burden, and maintaining reliability. This paper describes a pilot study to validate the RISE CPP as a tool to support clinician diagnosis of autism. Thirty-eight caregiver-child dyads (24-41 months, M = 34, SD = 4; 86% male) completed a remote parent-mediated assessment at home (RISE CPP) and an in-lab clinician-led assessment (Autism Diagnostic Observation Schedule; ADOS-2). Independent clinician diagnosis based on observations across the remote and in-lab assessments showed agreement for all but one child (K = .89). Clinicians completing in-person and remote assessments reported similar levels of confidence in their diagnoses, t(37) = 0.93, p = .36, d = .15. Mixed-methods analysis revealed unique benefits and challenges to the remote and in-person assessments and suggested that both assessments were acceptable to caregivers. Results provide preliminary support for the RISE CPP as a diagnostic tool. The remote administration may increase equity for clinical and research diagnostic assessments among families who are traditionally underserved and underrepresented in research.

Purpose: Past research highlights the different facilitators and barriers that caregivers of children on the autism spectrum experience during the transition to kindergarten and when navigating special education services. Caregivers who identify as Hispanic and/or Latine may face distinct challenges during this process, such as language differences, differences in understanding autism and special education, and barriers to advocating for their child. Hispanic and Latine caregivers also have strengths, resources, and strategies (i.e. cultural capital) that they use during this time. However, there is little research aimed at understanding the unique experiences of Hispanic and Latine caregivers of autistic children during their entry to kindergarten.

Methods: To address this shortcoming, the current study used qualitative methods and thematic analysis to explore the transition to kindergarten experiences of four caregivers of autistic children.

Results: This study identified strengths, supportive practices, and challenges that participants experienced fell under four major themes: importance of proactive and ongoing partnerships between caregivers and schools, navigating unfamiliar language and processes, the need for dissemination of information about autism to teachers and support from trusted systems. Themes highlighted challenges such as communication differences, unfamiliar school processes, community and teacher misconceptions about autism. Facilitators the transition included proactive communication, shared goals and partnerships with school. Yosso's Community Cultural Wealth Framework is integrated into the discussion of themes and the forms of cultural capital participants used to support their child.

Conclusion: Recommendations for practice and research to support Hispanic and Latine autistic children during the kindergarten transition are provided.

Children with autism and their parents face daily challenges that may be stressful for both. However, little is known about biological stress (hair cortisol concentrations [HCC]) in these families and its connection to children's health outcomes. This study investigates biological stress in children with autism and their parents and its associations with child mental health, eating behavior and BMI. Stress was measured in 102 young children with autism and their parents (101 mothers, 86 fathers) using HCC and self-reported parenting stress (OBVL). Child mental health was measured through autism symptoms (ADOS-2, SRS-2) and problem behavior (CBCL). Child eating behavior (CEBQ) and BMIz were also measured. Children with autism had higher HCC than their peers. Child HCC was not linked to mental health, eating behavior, or BMIz. Maternal stress (self-reported and HCC) was associated with child problem behavior. In fathers, self-reported parenting stress correlated with child autism symptoms (SRS-2) and behavior problems. Both parents' self-reported stress was associated with child eating behavior, specifically emotional undereating and overeating. In conclusion, higher HCC levels in children with autism in comparison to children from the general population, suggest differences in stress-regulation in children with autism. Given these findings, monitoring HCC in research and clinical practice could improve our understanding of stress-regulation in children with autism. The association between parental stress and children's mental health and eating behaviors, underscores the importance of considering family dynamics in clinical (preventive) interventions and in further research that addresses the mental and physical health of children with autism.

Purpose: The self is a multidimensional concept that can be represented at a pre-reflective (first-order) level, at a deeper, reflective level (second-order), or even at a meta-level (representing one's own thoughts, i.e. self-related mentalizing). Since self-related processing and mentalizing are crucial for social cognition, both constructs have been researched in individuals with autism, who experience persistent socio-communicative difficulties. Some studies suggested autism-related reductions of the self-bias, i.e. tendency to preferentially process self-related content; while others observed a decreased ability to mentalize on one's own thoughts in autism. However, prior research examined distinct levels of self-related processing in isolation, in the context of separate studies.

Methods: In this investigation, we directly compared self-bias, self- and other-related mentalizing within the same sample of adolescents with and without autism, to identify which of these are altered in this condition. Thirty adolescents with autism and 26 age- and IQ-matched controls performed a visual search task (first-order self-bias), a trait adjectives task (second-order self-bias), a feeling-of-knowing task (self-related mentalizing) and the Frith-Happé animations task (other-related mentalizing). Parents also completed two questionnaires (i.e. SRS, SCQ) assessing the adolescent's degree of autism traits.

Results: Our findings replicated previous research showing reduced other-related mentalizing in autism. However, we did not find any difference between adolescents with and without autism in terms of first- or second-order self-bias, nor in the ability to mentalize on one's own thoughts.

Conclusion: In line with recent investigations, our results do not support earlier claims of altered self-related information processing in autism.

Infants at elevated likelihood for or later diagnosed with autism typically have smaller vocabularies than their peers, as shown by the Mullen Scales of Early Learning (MSEL) and the MacArthur-Bates Communicative Developmental Inventory (CDI). However, the extent to which MSEL and CDI scores align remains unclear, especially across clinical and non-clinical populations. This study examined whether the concurrent validity of the MSEL and CDI differs based on autism likelihood and diagnosis. Data from 720 14-month-old infants were analysed, grouped by likelihood (elevated vs. typical) and diagnosis at 36 months (diagnosed vs. not diagnosed). Vocabulary scores were compared across both likelihood and diagnostic groups. Moderate correlations were observed between the MSEL and CDI in most groups (r_s range = [.34-.58]). One exception was that the expressive scores of elevated likelihood infants on the MSEL and CDI were more closely associated than the expressive scores of typical likelihood infants. Diagnosed infants had lower vocabulary scores than non-diagnosed peers on both the MSEL and CDI. The elevated likelihood group showed lower scores on the MSEL but not the CDI compared to typical likelihood infants. The moderate correlations suggest that the MSEL and CDI assess different aspects of language in infancy. These associations were weaker than previously reported in autistic children. Differences in vocabulary scores across likelihood and diagnostic groups highlight the need for further research to understand the association between these measures.

Many children with ASD exhibit difficulties with emotion regulation that greatly impair functioning. Certain intrinsic correlates of dysregulation have been identified in this population, but the search for potential environmental influences has been less fruitful. The current study examined several aspects of parenting as correlates of observed regulation in Autistic children, as measured in both parent-child and independent regulatory contexts. A diverse sample of 76 children with ASD aged 6 to 10 years participated in frustrating laboratory tasks with and without their primary caregivers, and the caregivers completed a parenting questionnaire. Emotion regulation, parental scaffolding, and gentle guidance were coded from videotaped interaction, and scores of parental involvement, positive parenting, and inconsistent discipline were obtained through parent report. Differential relations were observed between parenting and children's regulation when considered across contexts, with parental scaffolding associated with children's dyadic regulation and parents' reports of their involvement and discipline associated with children's independent regulation. Findings support previous evidence identifying a potential delay in the internalization of parental co-regulatory support in Autistic children, and highlight parental involvement as a previously unidentified unique correlate of independent regulation in this population. Implications for conceptualizations of emotion regulation in autism are discussed as is the importance of extending findings through further longitudinal research.

The current study examined the associations between internalizing symptoms, social motivation, and gender among autistic and non-autistic youth. Caregivers of 386 participants age 6 to 14 years completed measures of their child's internalizing symptoms and social motivation. Correlation and hierarchical regression analyses were conducted to compare internalizing symptoms and social motivation across autistic and non-autistic girls and boys. Social motivation was found to be higher among non-autistic participants compared to autistic participants, with no significant gender differences observed in social motivation within groups. Social motivation was found to be a significant predictor of internalizing symptoms. The association between social motivation and internalizing symptoms varied by gender and diagnostic status. Higher internalizing symptom scores were associated with lower social motivation among autistic girls, non-autistic girls, and non-autistic boys, but no association was found among autistic boys. The current study found that the relations between social motivation and anxiety, depression, and somatization symptoms in autistic youth varied by gender. The strong association between internalizing symptoms and social motivation among autistic girls and not autistic boys may be due to the unique social experiences and expectations associated with the intersecting gender and neurodivergent identities of autistic girls. The findings of the current study underscore the value of adopting an intersectionality perspective by considering both the influence of gender and neurodivergent identities together when addressing the social experiences and mental health of autistic youth.

Objective: To identify the tools used to assess eating behaviors in individuals with Autism Spectrum Disorder (ASD) and summarize their distribution, citation rates, journal publication, JCR scores, and psychometric properties.

Methods: A literature review was conducted to identify studies on eating behavior in individuals with ASD. The search included various descriptors and combinations of keywords in databases such as Medline/PubMed, Science Direct, Scopus, SciELO, and Web of Science. The studies were filtered to focus on articles published in the last five years. Thirty-seven relevant studies were identified and analyzed to summarize the tools used, their distribution in the literature, citation rates, and psychometric properties.

Results: Thirty-seven relevant studies were identified. The Journal of Autism and Developmental Disorders published the most studies (5). The Brief Autism Mealtime Behavior Inventory (BAMBI) was the most frequently used instrument, appearing in 15 studies, followed by the Behavioral Pediatrics Feeding Assessment Scale (BPFAS) in 8 studies. Both instruments demonstrated solid psychometric properties, with BAMBI showing good internal consistency (α = 0.88) and BPFAS a Cronbach's alpha of 0.82.

Conclusion: Most of the instruments used in studies on eating behavior in individuals with ASD demonstrate satisfactory psychometric properties. BAMBI and BPFAS stand out for their widespread use but are limited to covering only specific age ranges.
