PURPOSE: Obsessive-compulsive disorder (OCD) and autism are characterized by the presence of repetitive behaviors. Differentiating between repetitive behaviors attributable to a diagnosis of autism, and those attributable to OCD, poses challenges for differential and co-occurring diagnosis. Differentiation is important to inform appropriate supports and interventions for phenotypically similar but functionally distinct behaviors. In this systematic review, the quantitative literature was examined to explore the similarities and differences in repetitive behaviors (including restricted and repetitive behaviors and interests, and obsessive-compulsive behaviors) in autistic individuals and those with OCD, and those with co-occurring diagnoses, in terms of: (1) expression, (2) content, and (3) associated factors...

PURPOSE: Recent research has suggested that autism may present differently in girls compared to boys, encouraging the exploration of a sex-differential diagnostic criteria. Gender differences in diagnostic assessments have been shown on the ADOS-II, such that, on average, females score significantly lower than males on all scales and are less likely to show atypicality on most items related to social communicative difficulties. Yet, gender differences in the latent structure of instruments like the ADOS-II have not been examined systematically...

PURPOSE: Professional supports play an important role in aiding autistic children's learning, participation, and overall wellbeing. Yet, limited research exists on stakeholders' perspectives and preferences regarding targeted outcomes for children undergoing support facilitated by professionals. This study investigated stakeholder views on the priority and appropriateness of outcomes intentionally targeted during the provision of supports to autistic children. METHOD: A survey of 181 participants (including 72 autistic adults, 85 parents, and 69 professionals) from Australia and New Zealand was conducted...

Past research has highlighted the importance of early identification of developmental differences to improve targeted access to early interventions or supports. As such, it is of particular importance in the context of children at elevated likelihood of autism (such as where an older sibling has a diagnosis of autism), to better understand when and which early concerns are important as predictors of which children will benefit from pre-diagnostic supports. This study explored the number and frequency of retrospective parent reported concerns within the first year of life for children diagnosed with autism, both those who had an older sibling diagnosed with autism and those who did not, as well as for undiagnosed siblings...

This study applied the functional near-infrared spectroscopy (fNIRS) to investigate frontal activity in autism when performing verbal fluency test and emotion recall task. We recruited 32 autistic adults without intellectual disability and 30 typically-developing controls (TDC). Prefrontal hemodynamic changes were evaluated by fNIRS when the participants performed the verbal fluency test and emotion recall task. fNIRS signals in the prefrontal cortex were compared between autism and TDC. Compared to TDC, autistic adults showed comparable performance on the verbal fluency test but exhibited lower frontal activity on the vegetable category...

Children with autism spectrum disorder (ASD) are five times more likely to have feeding difficulties than neurotypical peers, although the majority of evidence describes feeding difficulty in children age 2 years and older. The purpose of this study is to systematically review the literature on feeding characteristics of children age 0-24 months who were later diagnosed with ASD with an emphasis on the measurement tools used to assess these feeding behaviors. We conducted a systematic review of the literature using PRISMA guidelines...

The post-secondary transition for autistic youth is a complex process, with hopes and expectations serving as malleable mediators often overlooked in research and practice. Career awareness, exploration, and counseling services play a critical role in facilitating vocational transition, but the vocational hopes and expectations of autistic youth and their parents are often disregarded. This study aims to explore these aspirations and their impact on the vocational transition process, seeking to harmonize elements to better align with the needs of autistic youth and their families...

Individuals with Autism Spectrum Disorder (ASD) present atypical sensory processing in the perception of moving stimuli and biological motion. The present study aims to explore the performance of young adults with ASD in a time to contact (TTC) estimation task involving social and non-social stimuli. TTC estimation involves extrapolating the trajectory of a moving target concealed by an occluder, based on the visible portion of its path, to predict the target's arrival time at a specific position. Sixteen participants with a diagnosis of level-1 ASD (M = 19...

PURPOSE: The impact of well-crafted IEP goals on student outcomes is well-documented, but creating high-quality goals can be a challenging task for many special education teachers. This study aims to investigate potential effectiveness of using ChatGPT, an AI technology, in supporting development of high-quality, individualized IEP goals for preschool children with autism. METHODS: Thirty special education teachers working with preschool children with autism were randomly assigned to either the ChatGPT or control groups...

The purpose of this project was to investigate potential correlates of family life impairment in families of young autistic children. This project incorporated measures of specific child and parent challenges in addition to a commonly used unidimensional measure of autism characteristics. In this way, we could assess whether such challenges explain variance in family life impairment, and whether their inclusion diminish associations between autism characteristics and family life impairment. Cross-sectional data were collected from 564 parents of autistic children aged 2 to 5 years who participated in a larger online study...

Autism spectrum disorder (ASD) is a multifactorial, pervasive neurodevelopmental disorder affecting 1 in 36 children in the United States. Given the rising prevalence and significant economic and social costs associated with ASD, it is critical that continued efforts be made towards better understanding the underlying etiology as well as management of the condition and its commonly associated comorbidities. It has been estimated that upwards of 70% of children with ASD have a positive history of gastrointestinal (GI) symptoms...

In recent years, there has been a proliferation of instruments for assessing mental health (MH) among autistic people. This study aimed to review the psychometric properties of broadband instruments used to assess MH problems among autistic people. In accordance with the PRISMA guidelines (PROSPERO: CRD42022316571) we searched the APA PsycINFO via Ovid, Ovid MEDLINE, Ovid Embase and the Web of Science via Clarivate databases from 1980 to March 2022, with an updated search in January 2024, to identify very recent empirical studies...

The primary purpose of the current pilot study was to test the effects of an adapted and collaborative intervention model with a systematic teaching approach on Latina Spanish-speaking caregivers' use of EMT en Español Para Autismo strategies with their young children on the autism spectrum. A multiple baseline across behaviors single case design was replicated across two dyads. A series of family interviews and a direct therapist-child intervention phase supported individualization of the intervention...

Autism spectrum disorder (ASD) is characterized by impairments in many functional areas requiring long-term interventions to promote autonomy. This study aims to map The Sensory Profile™ 2 (SP-2), one of the most widely used assessment tools in children with ASD, with the International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY), developed by the World Health Organization (WHO). This will allow the identification of the functional dimensions covered by this instrument and the comparison with the ICF shortlist proposed for autism (ICF Core Set [ICF-CS])...

PURPOSE: Non-verbal utterances are an important tool of communication for individuals who are non- or minimally-speaking. While these utterances are typically understood by caregivers, they can be challenging to interpret by their larger community. To date, there has been little work done to detect and characterize the vocalizations produced by non- or minimally-speaking individuals. This paper aims to characterize five categories of utterances across a set of 7 non- or minimally-speaking individuals...

Children with autism often display differences in functional and symbolic play and may experience barriers to social inclusion with peers in preschool settings. Therefore, interventions supporting social play between children with autism and their peers that can be feasibly implemented by teachers in inclusive settings are needed. A teacher-implemented peer-mediated Stay Play Talk (SPT; Goldstein et al. in Top Lang Disord 27(2):182-199, 2007) intervention package targeting the type of play children with autism engage in with peers was implemented using a concurrent multiple baseline design across four participant/peer dyads...

Children with neurodevelopmental disorders are at risk for burn injury, but the clinical outcomes, particularly mortality, are unknown in this patient population in the United States (U.S.). The main objectives of this study are to evaluate (1) subject characteristics; (2) burn injury type; (3) clinical care provided; and (4) mortality in children with autism spectrum disorder (ASD), hypothesizing that this patient population has similar mortality and critical care management requirements when compared to children without ASD...

Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum disorder (ASD). The current study evaluates differences in resting frontal gamma power between young autistic and NT children and tests whether gamma power is uniquely associated with individual differences in expressive language, receptive language and non-verbal cognitive abilities in autistic and NT children...

PURPOSE: Diagnostic accuracy of autism spectrum disorder (ASD) is crucial to track and characterize ASD, as well as to guide appropriate interventions at the individual level. However, under-diagnosis, over-diagnosis, and misdiagnosis of ASD are still prevalent. METHODS: We describe 232 children (MAge = 10.71 years; 19% female) with community-based diagnoses of ASD referred for research participation. Extensive assessment procedures were employed to confirm ASD diagnosis before study inclusion...

PURPOSE: This study aimed to explore the effect of family-professional partnerships in adapted physical education on the fundamental motor skills, physical activity levels, and adaptive behaviors of children with autism spectrum disorder (ASD) and on parental satisfaction. METHODS: A randomized controlled trial design was used, with pre-and post-intervention evaluations. Participants (n = 40), including children with ASD and their parents, were divided into three groups: (a) a family-school group (FSG-A, n = 14), (b) a school group (SG-B, n = 13), and (c) a control group (CG-C, n = 13)...
