ABSTRACT

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. More specifically, among 45 autistic young adults, three dimensions of self-reported stigma (discrimination, disclosure, and positive aspects) were examined in relation to self-esteem, self-efficacy, social satisfaction and adaptive social functioning. Quantitative analyses revealed higher reported discriminative and disclosure stigma were significantly associated with lower self-efficacy. Increased experience with all types of stigma were associated with lower social satisfaction. Greater reported disclosure stigma was also associated with lower self-esteem. Qualitative interviewing among eight autistic young adults helped to better understand the nature of stigma and the impact of these experiences. Thematic analysis of the qualitative data revealed that all of the participants experienced stigma in the form of exclusion or isolation and that a majority also experienced verbal bullying. Many of the negative interactions came from educators, peers, and family members. Most participants indicated that these stigmatizing interactions directly contributed to decreased social satisfaction, diminished self-efficacy, and lowered self-esteem. A greater understanding of the negative consequences of stigma can inform efforts to increase awareness and acceptance of autism.

ABSTRACT

Background: Autistic people in France have called for community education to reduce autism stigma. As such, training is needed to help university students appreciate autistic peers and autistic people they may work with in their future careers. Methods: We adapted an autistic-affirming training from a training developed in other cultural contexts and evaluated it with 107 university students in France using a pretest-post-test design. Results: Questionnaire responses suggested that our brief online training helped improve attitudes toward inclusion, autism knowledge, and stigma among future educators and psychologists in France. Participants' open-ended definitions of autism revealed increased alignment with the neurodiversity movement after training. Conclusions: Findings suggest that wider-scale autistic-led adaptations of autism trainings like the one described in this report could begin to ameliorate autism stigma in France.


Why is this an important issue?: Autistic people in France have been treated very badly in the past. They have been left out of school and hurt by professionals. They still face stigma. This means they are often misunderstood, made fun of, and excluded. Some are forced to take medications they do not want. Autistic people in France have been trying to help other people in France understand autism. What was the purpose of this study?: We wanted to see whether autism training could help university students in France to better understand autistic people. We wanted to see whether our training could help students appreciate autistic people more (or lower stigma). We also wanted to see whether the training could help students understand that it is important to include autistic people in classes with other students at school. What did the researchers do?: Researchers in France, Lebanon, and the United States modified an autism training that had been used in other countries. The training was autistic affirming, which means it taught people to listen to autistic people and to see their strengths. We translated it into French. We included training topics that French collaborators thought were important. We asked university students in France who were studying education and psychology to do our training online. We also asked them to fill out surveys about autism. What were the results of the study?: After doing our training, students knew more about autism than they did before training. Some learned that autism is part of a person for their whole life. They seemed to appreciate autistic people more after training. They also agreed that it is important to include autistic people in school with other students more than they had before. What do these findings add to what was already known?: This study shows that autistic-affirming training can also help people in France appreciate autistic people. Much autism training only focuses on stigma and knowledge. Our training may also have helped future educators and clinicians understand how important it is to include autistic people in school with other students. What are potential weaknesses in the study?: The students in our study were mostly women. They were all training for jobs where they can help people. We do not know whether our training would help other French people. We also cannot be sure that our training really helped the students who did it. Students may have been dishonest about how they felt about autism. In future studies, people should see whether training changes what people do, not just what they say. How will these findings help autistic adults now or in the future?: By teaching students in France about autism, we hope to begin to help make life better for autistic people in France. We hope studies like this will help people to understand autistic people better. We also hope more people conduct trainings like that used in this study around the world to improve understanding and treatment of autistic people.

ABSTRACT

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. The current study compiled data from 6830 participants collected using adapted versions of the ASK-Q administered in 13 different countries, representing four different continents. Structural equation modeling was used to examine how autism knowledge varied across country and individual factors. Results reveal cross country variability with a large, 17-point difference between the countries with the highest knowledge (Canada) and the lowest knowledge (Lebanon). As expected, countries with higher economies had higher levels of knowledge. We also documented differences based on country worldview, participant occupation, gender, age, and education level. These results help to identify specific regions and populations that might most need greater information about autism.

ABSTRACT

LAY ABSTRACT: Autistic university students are often left out because people do not understand autism. We wanted to help people understand autism. Most autism trainings are not made by autistic people. Autistic people know what it is like to be autistic. So autistic people may be the best teachers when it comes to teaching about autism. Autistic students and non-autistic professors made an autism training. The students made videos for the training. They also helped make questions to see what people learned from the trainings. Professors who are not autistic made a training on their own. Students in New York City tried out the trainings. After they answered questions, they did either the training the autistic students helped make or the training made by only professors. Then, they answered questions again. We learned from the students how to make our trainings better. Then, students from two universities in the United States and one university in Lebanon did our trainings and questions. Both trainings made hidden feelings about autism better. The training autistic students helped make taught students more than the training professors made on their own. The autistic-led training also helped students accept autism more. These studies show that autistic students can make autism research and trainings better. At the end of this article, autistic students share their ideas for how to make autism trainings even better in the future.

ABSTRACT

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. Accurately identifying ASD was associated with reduced explicit stigma; identifying CD led to more stigma. Participants who identified as White implicitly associated the White child with ASD and the Black child with CD. A trend in the reverse direction was observed among Black participants. Implicit and explicit biases were unrelated. Findings highlight a need for trainings to ameliorate biases favoring one's in-group.

ABSTRACT

Autism spectrum disorder in China differs considerably from autism spectrum disorder in the West in terms of prevalence estimates, education opportunities, and life outcomes of autistic people. The lack of autism spectrum disorder awareness could be a key factor underlying the disparities. To date, there has been no evaluation of autism spectrum disorder knowledge among the general public of China. Using the Autism Stigma and Knowledge Questionnaire developed for use in diverse cultural contexts, this study uncovered profoundly different public views about autism spectrum disorder in China compared with the United States. Determined by cognitive diagnosis modeling, 86%-91% of the surveyed U.S. citizens (N = 1127) achieved adequate autism spectrum disorder knowledge in diagnosis/symptoms, etiology, and treatment, whereas for the Chinese citizens (N = 1254) the percentages were only 57%-65%. Moreover, 14% of the participants from the United States were classified to endorse autism spectrum disorder stigma; in comparison, 38% of the Chinese participants endorsed autism spectrum disorder stigma. The Chinese citizens displayed knowledge deficits primarily in the areas of autism spectrum disorder core symptoms, comorbid intellectual impairment, and prognosis. Sociodemographic factors associated with the Chinese citizen's misconceptions included gender, ethnicity, social economic factors, among others. These results have important implications for increasing public awareness and promoting community participation for autistic individuals in China.Lay abstractASD in China differs considerably from ASD in the West in terms of prevalence estimates, education opportunities and life outcomes of autistic people. The lack of ASD awareness could be a key factor underlying these disparities. We asked 1127 U.S. citizens and 1254 Chinese citizens about their autism knowledge using the Autism Stigma and Knowledge Questionnaire (ASK-Q).The results indicated profoundly different public views about ASD in China compared to the U.S. Specifically, only 57%-65% of the Chinese citizens demonstrated adequate ASD knowledge compared to 86%-91% in the U.S. citizens. Fourteen percent of the U.S. citizens were shown to hold stigma beliefs towards ASD; in comparison, 38% of the Chinese citizens indicated ASD stigma. The Chinese citizens displayed misconceptions about ASD related to symptoms, causes, and possible long-term outcomes. In China but not in the U.S., male citizens and citizens with lower social economic status were more likely to have misconceptions about ASD than others were. The findings of this research can help increase public awareness about ASD and create a more inclusive environment for autistic people in China.

ABSTRACT

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. A search was conducted between March and May 2017. Four reviewers extracted data and performed a mixed-methods quality appraisal of publications. Thirty-seven publications representing 32 unique programmes were identified. Publications described a highly diverse range of Parent Education and Training programmes across 20 countries and all continents except South America. The majority were group-based, but varied significantly in goals, modalities and duration. The majority of studies (86.4%) reported positive outcomes in relation to the core study objectives and only two studies reported some negative findings. Quality appraisal rated only 27% of studies to have met all the methodological quality criteria. Implementation factors such as manualisation, fidelity and cost were commented on infrequently. In spite of the clear need for Parent Education and Training programmes, our findings show that the research evidence-base in autism spectrum disorder outside the United States is relatively small, non-representative and in need of methodological quality improvements.

ABSTRACT

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. in Autism Res 1(1):31-42, 2008). This study evaluated both theories in children diagnosed with ASD (n = 16) and a group of TD children (n = 20) using eye tracking and demonstrated that distractor type only impacted the proportion of dwell time on faces in the TD group, but not the ASD group. These results provide support for the social motivation theory because gaze duration for faces among children with ASD was diminished regardless of whether the non-social stimuli presented was a CI or control object.

ABSTRACT

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. Explicit and implicit attitudes were measured at the start and end of a semester among IPSE volunteer peer mentors (n = 17) and an uninvolved student group (n = 14). Findings indicate that volunteers demonstrated lower discomfort after their volunteer experience, as measured by the Attitudes Toward Intellectual Disability Questionnaire (ATTID). Volunteers also demonstrated higher knowledge of causes and preference for interaction with people with ID than nonvolunteers. This demonstrates that volunteer involvement in IPSE positively impacts attitudes toward people with ID among typically matriculating college students.

ABSTRACT

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. RECENT FINDINGS: Forty studies were included. Low-income and racial/ethnic minority youth on the autism spectrum were less likely to participate in transition planning meetings, enroll in postsecondary education, find competitive employment after high school, live independently, participate in social activities, and receive health care transition services than their White and higher income peers on the autism spectrum. Racial/ethnic minority and low-income youth on the autism spectrum were more likely to be disconnected from educational, occupational, and social activities upon entering adulthood. Future research should explore the mechanisms underlying these disparities as a first step to addressing them.

ABSTRACT

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. ASK-Q items were selected based on ratings of face, construct, and cross-cultural validity by a group of 16 international researchers. Using Diagnostic Classification Modeling we confirmed the proposed factor structure and evaluated the statistical validity of each item among a lay sample of 617 participants.

ABSTRACT

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). Holding level of overall ADOS behavioral symptoms constant, we found significant item level bias (measurement noninvariance) for race and ethnicity on three ADOS items. Item-level bias was not apparent across gender. Although the magnitude of bias was small, our findings highlight the need to reevaluate norms and operational definitions used in assessments to increase ASD diagnostic accuracy among culturally-diverse groups.

ABSTRACT

Nutrition-related chronic health conditions among older adults are a growing concern. In this study, nutrition education materials were created for use in senior centers by graduate nutrition students. After the materials were presented, focus groups were conducted with participants (n = 62) to obtain feedback on the content and presentation. Findings related to the participant's knowledge of nutrition-related information, strategies to improve future class sessions, and participant recruitment will be discussed. These findings will be useful to program administrators as they develop nutrition programs for older adults who are vulnerable to nutrition-related health problems.

ABSTRACT

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. Measures used in each study were evaluated in terms of psychometric strength. Of the 67 studies reviewed, only 7% were rated as using a measure with strong psychometric support compared to 45% that were rated as using a measure with no reported psychometric support. Additionally, we examined content overlap and subdomains of autism spectrum disorder knowledge assessed (e.g. etiology, symptoms) and cross-cultural adaptation procedures utilized in the field. Based on these findings, the need for a cross-culturally valid and psychometrically sound measure of autism spectrum disorder knowledge is discussed and recommendations for improving current assessment methods are presented, including suggestions for measure subdomains.

ABSTRACT

BACKGROUND: Laboratory-based studies on neuromuscular control after concussion and epidemiological studies suggest that concussion may increase the risk of subsequent musculoskeletal injury. OBJECTIVE: The purpose of this study was to determine if athletes have an increased risk of lower extremity musculoskeletal injury after return to play from a concussion. METHODS: Injury data were collected from 2006 to 2013 for men's football and for women's basketball, soccer and lacrosse at a National Collegiate Athletic Association Division I university. Ninety cases of in-season concussion in 73 athletes (52 male, 21 female) with return to play at least 30 days prior to the end of the season were identified. A period of up to 90 days of in-season competition following return to play was reviewed for time-loss injury. The same period was studied in up to two control athletes who had no concussion within the prior year and were matched for sport, starting status and position. RESULTS: Lower extremity musculoskeletal injuries occurred at a higher rate in the concussed athletes (45/90 or 50 %) than in the non-concussed athletes (30/148 or 20 %; P < 0.01). The odds of sustaining a musculoskeletal injury were 3.39 times higher in the concussed athletes (95 % confidence interval 1.90-6.05; P < 0.01). Overall, the number of days lost because of injury was similar between concussed and non-concussed athletes (median 9 versus 15; P = 0.41). CONCLUSIONS: The results of this study demonstrate a relationship between concussion and an increased risk of lower extremity musculoskeletal injury after return to play, and may have implications for current medical practice standards regarding evaluation and management of concussion injuries.

ABSTRACT

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. Historically, in Western countries, parents have played a major role in increasing ASD awareness, advancing research, and encouraging empirically supported treatments. In the absence of established treatment services, parents of children with ASD have also learned to implement behavioral interventions to reduce the widening skills gaps. This article describes the development of an intervention designed to inform parents in Tanzania about ASD and empirically supported behavioral strategies. Preliminary data, collected from a clinical implementation with 29 Tanzanian families of children diagnosed with ASD or general developmental delays, support the initial feasibility and acceptability of this intervention. This brief intervention may help to ameliorate treatment disparities due to insufficient regional knowledge, language barriers, or limited service availability and may help improve functional outcomes among Tanzanian children with ASD.

ABSTRACT

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). An examination of the association between JA and a range of functional correlates (cognitive and adaptive) revealed JA was significantly related to verbal (VIQ) and non-verbal (NVIQ) cognitive ability as well as all domains of adaptive functioning (socialization, communication, and daily living skills). Additional analyses examined the degree to which the relation between adaptive abilities (socialization, communication, and daily living skills) and JA was maintained after taking into account the potentially mediating role of verbal and nonverbal cognitive ability. Results revealed that VIQ fully mediated the relation between JA and adaptive functioning, whereas the relation between these adaptive variables and JA was only partially mediated by NVIQ. Moderation analyses were also conducted to examine how verbal and non-verbal cognitive ability and gender impacted the relation between JA and adaptive functioning. In line with research showing a relation between language and JA, this indicates that while JA is significantly related to functional outcomes, this appears to be mediated specifically through a verbal cognitive pathway.

ABSTRACT

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. To address these mixed findings, we focused on the potential moderating role of genes associated with hypothalamic-pituitary-adrenal axis reactivity. Participants included children (8-14 years old) of mothers with (n = 81) and without (n = 81) a history of depression. Eye movements were recorded while children passively viewed arrays of angry, happy, sad, and neutral faces. DNA was obtained from buccal cells. Children of depressed mothers exhibited more sustained attention to sad faces than did children of nondepressed mothers. However, it is important that this relation was moderated by children's genotype. Specifically, children of depressed mothers who carried reactive genotypes across the corticotropin-releasing hormone type 1 receptor (CHRH1) TAT haplotype and FK506 binding protein 5 (FKBP5) rs1360780 (but not the solute carrier family C6 member 4 [SLC6A4] of the serotonin transporter linked polymorphic region [5-HTTLPR]) exhibited less sustained attention to sad faces and more sustained attention to happy faces. These findings highlight the role played by specific genetic influences and suggest that previous mixed findings may have been due to genetic heterogeneity across the samples.

ABSTRACT

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. This genotype-phenotype investigation may provide insight into how OXTR conveys risk for social impairment. The current study investigated 10 SNPS in the OXTR gene that have been previously shown to be associated with ASD. We examine the association of these SNPs with both a social phenotype and a repetitive behavior phenotype comprised of behaviors commonly impaired in ASD in the Simons simplex collection (SSC). Using a large sample to examine the association between OXTR and ASD (n = range: 485-1002), we find evidence to support a relation between two OXTR SNPs and the examined social phenotype among children diagnosed with ASD. Greater impairment on the social responsiveness scale standardized total score and on several subdomains was observed among individuals with one or more copies of the minor frequency allele in both rs7632287 and rs237884. Linkage disequilibrium (LD) mapping suggests that these two SNPs are in LD within and overlapping the 3' untranslated region (3'-UTR) of the OXTR gene. These two SNPs were also associated with greater impairment on the repetitive behavior scale. Results of this study indicate that social impairment and repetitive behaviors in ASD are associated with genomic variation in the 3'UTR of the OXTR gene. These variants may be linked to an allele that alters stability of the mRNA message although further work is necessary to test this hypothesis.

ABSTRACT

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. This is the first known sudy to use eye-tracking to investigate the exact nature of attention biases among depressed children. To assess sustained attention, the current study used eye-tracking and a passive viewing task in which children viewed a series of four facial expressions (angry, happy, sad, neutral) presented simultatiously for 20 s on a computer screen. The current study compared the attentional allocation of currently depressed children (n = 19; M age = 11.21) to a group of never depressed children (n = 22; M age = 10.82). Consistent with earlier research with children, we found that children with current major or minor depression, compared to children with no history of depression, exhibited attentional avoidance of sad facial stimuil as well as some evidence for preferential attention to happy faces. This study provides additional evidence that although depressed children demonstrate mood congruent attentional biases like that observed depressed adults, the nature of these biases may reflect attentional avoidance of sad stimuli, rather than preferential attention.
