Various intervention usage is associated with positive outcomes for children with autism. However, the intensity of these interventions tends to be below recommendations, especially for minoritized children. This study aimed to examine how average weekly intervention hours among children vary by sociodemographic factors.

The Autism Stigma and Knowledge Questionnaire (ASK-Q) was developed to assess autism knowledge across cultural contexts. The current study aimed to examine cultural equivalence of the measure using a large, international database. These analyses identified 18 items in need of examination for removal or revision.

A recent meta-analysis reveals almost half of autistic individuals experience some form of victimization in their lifetime, including bullying and other forms of stigma. Research among caregivers of autistic individuals demonstrates that stigma can have a long-lasting impact on other aspects of a social identity, such as self-esteem, but less research has specifically examined this among autistic adults themselves, in spite of research suggesting these are likely constructs that contribute to the internalization of stigma and subsequent mental health consequences. The current study used a mixed method approach to assess the relation between stigma and several components of social identity and social functioning.

Substantial variability exists with regard to autism service provision around the world. Service disparities observed in many low- and middle-income countries may be driven, in part, by limited autism knowledge; however, measurement limitations have made it difficult to quantify autism knowledge across countries. The current study uses the autism stigma and knowledge questionnaire (ASK-Q) to quantify autism knowledge and stigma between different countries and demographics.

Are implicit and explicit biases related to ASD identification and/or stigma? College students (N = 493) completed two IATs assessing implicit stigma and racial biases. They evaluated vignettes depicting a child with ASD or conduct disorder (CD) paired with a photo of a Black or White child. CD was more implicitly and explicitly stigmatized than ASD.

Article Synopsis
  • Autism spectrum disorder (ASD) in China shows significant differences in prevalence, educational opportunities, and life outcomes compared to the West, attributed partly to lower awareness of ASD.
  • A study using the Autism Stigma and Knowledge Questionnaire revealed that only 57%-65% of Chinese citizens had adequate knowledge about ASD, compared to 86%-91% of U.S. citizens.
  • Stigma surrounding ASD is notably higher in China (38%) than in the U.S. (14%), with specific knowledge gaps identified in core symptoms, intellectual impairment, and prognosis, influenced by various sociodemographic factors.

Social motivation theory states that individuals with ASD find social stimuli less rewarding (Chevallier et al. in Trends Cognit Sci 16(4):231-239, 2012). An alternative theory suggests that competition from circumscribed interests (CIs) may better account for diminished social attention (Sasson et al.

People with intellectual disability (ID) experience negative consequences as a result of stigmas held by the public. Students with ID involved in inclusive postsecondary education (IPSE) programs demonstrate positive outcomes. This study examines the impact of an IPSE program on typically matriculating student attitudes toward ID.

Empowering families of children with autism spectrum disorder through education and training is best practice. A wide range of Parent Education and Training programmes are delivered around the globe, but there is limited knowledge about the characteristics of these programmes, or about the research methods and outcomes used to evaluate them, particularly in countries outside the United States. We, therefore, performed a scoping review of all peer-reviewed Parent Education and Training publications outside the United States.

Purpose Of Review: Few studies have examined disparities in autism services and functional outcomes over the life course. Transition to adulthood is an especially important developmental period, as it sets up trajectories of adult functioning. This systematic review summarizes patterns of service use and transition outcomes according to race, ethnicity, and socioeconomic characteristics over the transition to adulthood.

ASD knowledge deficits contribute to disparities in the timing and quality of ASD services. To address the limitations with existing measures of ASD knowledge, we developed and examined the Autism Stigma and Knowledge Questionnaire (ASK-Q), which comprehensively assesses multiple subdomains of ASD knowledge while maintaining strong psychometric support and cross-cultural utility. ASK-Q items derived from the published research are organized into four subscales: (i) diagnosis, (ii) etiology, (iii) treatment, and (iv) stigma.

The Autism Diagnostic Observation Schedule (ADOS) is widely used to assess symptoms of autism spectrum disorder (ASD). Given well-documented differences in social behaviors across cultures, this study examined whether item-level biases exist in ADOS scores across sociodemographic groups (race, ethnicity, and gender). We examined a subset of ten ADOS items among participants (N = 2458).

Joint attention skills have been shown to predict language outcomes in children with autism spectrum disorder (ASD). Less is known about the relationship between joint attention (JA) abilities in children with ASD and cognitive and adaptive abilities. In the current study, a subset of items from the Autism Diagnostic Observation Schedule (ADOS), designed to quantify JA abilities, were used to investigate social attention among an unusually large cross-sectional sample of children with ASD (n = 1061).

Despite the global presence of autism spectrum disorder (ASD), a paucity of treatment services exists in Tanzania and other low- and middle-income countries. The effect of delayed or low-quality treatments is enduring and contributes to lifelong variability in ASD-related functional impairments. Service disparities in Tanzania derive in part from a widespread lack of national ASD knowledge.

Autism spectrum disorder-specific knowledge deficits contribute to current disparities in the timing and quality of autism spectrum disorder services throughout the United States and globally. This study conducted a systematic review of Western and International literature to examine measures used to assess autism spectrum disorder knowledge. This review identified 44 unique autism spectrum disorder knowledge measures across 67 studies conducted in 21 countries.

Oxytocin regulates social behavior in animal models. Research supports an association between genetic variation in the oxytocin receptor gene (OXTR) and autism spectrum disorders (ASD). In this study, we examine the association between the OXTR gene and a specific social phenotype within ASD.

Information-processing biases may contribute to the intergenerational transmission of depression. There is growing evidence that children of depressed mothers exhibit attentional biases for sad faces. However, findings are mixed as to whether this bias reflects preferential attention toward, versus attentional avoidance of, sad faces, suggesting the presence of unmeasured moderators.

Abstract In many lower-income countries, there is a paucity of assessment services for autism spectrum disorders (ASD)., Guidelines will be provided for conducting cross-cultural assessments in the context of limited validated resources in Tanzania. By examining behavioral, social, and adaptive differences we were able to provide differential diagnostic evaluations aligning with best practice standards for 41 children in Tanzania age 2-21 years.

Cognitive theories state attentional biases contribute to the development and maintenance of depression. Like depressed adults, there is growing evidence for the presence of attentional biases to sad stimuli in depressed youth. Although the direction of this bias among children remains unclear, preliminary evidence indicates attentional avoidance of sad stimuli in children.
