RESUMEN
Previous studies have reported alterations in cortical thickness in autism. However, few have included enough autistic females to determine if there are sex specific differences in cortical structure in autism. This longitudinal study aimed to investigate autistic sex differences in cortical thickness and trajectory of cortical thinning across childhood. Participants included 290 autistic (88 females) and 139 nonautistic (60 females) individuals assessed at up to 4 timepoints spanning ~2-13 years of age (918 total MRI timepoints). Estimates of cortical thickness in early and late childhood as well as the trajectory of cortical thinning were modeled using spatiotemporal linear mixed effects models of age-by-sex-by-diagnosis. Additionally, the spatial correspondence between cortical maps of sex-by-diagnosis differences and neurotypical sex differences were evaluated. Relative to their nonautistic peers, autistic females had more extensive cortical differences than autistic males. These differences involved multiple functional networks, and were mainly characterized by thicker cortex at ~3 years of age and faster cortical thinning in autistic females. Cortical regions in which autistic alterations were different between the sexes significantly overlapped with regions that differed by sex in neurotypical development. Autistic females and males demonstrated some shared differences in cortical thickness and rate of cortical thinning across childhood relative to their nonautistic peers, however these areas were relatively small compared to the widespread differences observed across the sexes. These results support evidence of sex-specific neurobiology in autism and suggest that processes that regulate sex differentiation in the neurotypical brain contribute to sex differences in the etiology of autism.
RESUMEN
Adolescence has been characterized as a period of risky and possibly suboptimal decision-making, yet the development of decision-making in autistic adolescents is not well understood. To investigate decision-making in autism, we evaluated performance on 2 computerized tasks capturing decision-making under explicit risk and uncertainty in autistic and non-autistic adolescents/young adults ages 12-22 years. Participants completed the Game of Dice Task (32 IQ-matched participant pairs) to assess decision-making under explicit risk and the modified Iowa Gambling Task (35 IQ-matched pairs) to assess decision-making under uncertainty. Autistic participants overall made riskier decisions than non-autistic participants on the Game of Dice Task, and the odds of making riskier decisions varied by age and IQ. In contrast, the autistic group showed comparable levels of learning over trial blocks to the non-autistic group on the modified Iowa Gambling Task. For both tasks, younger autistic participants performed poorer than their non-autistic counterparts, while group differences diminished in older ages. This age-related pattern suggests positive development during adolescence on risk assessment and decision-making in autism but also implies differential developmental trajectories between groups. These findings also suggest differential performance by the risk type, with additional complex influences of IQ and fluid cognition, which warrants further investigations.

LAY ABSTRACT: For many autistic children, the severity of their autism symptoms changes during middle childhood. We studied whether these changes are associated with the emergence of other mental health challenges such as anxiety and attention-deficit hyperactivity disorder. Children who had increased social-communication challenges had more anxiety and attention-deficit hyperactivity disorder symptoms and disruptive behavior problems than other children. Children who decreased their restricted and repetitive behaviors, on the contrary, had more anxiety. We discuss why these changes in autism symptoms may lead to increases in other mental health concerns.
RESUMEN
Introduction: Recent work challenged past findings that documented relational memory impairments in autism. Previous studies often relied solely on explicit behavioral responses to assess relational memory integrity, but successful performance on behavioral tasks may rely on other cognitive abilities (e.g., executive functioning) that are impacted in some autistic individuals. Eye-tracking tasks do not require explicit behavioral responses, and, further, eye movements provide an indirect measure of memory. The current study examined whether memory-specific viewing patterns toward scenes differ between autistic and non-autistic individuals. Methods: Using a long-term memory paradigm that equated for complexity between item and relational memory tasks, participants studied a series of scenes. Following the initial study phase, scenes were re-presented, accompanied by an orienting question that directed participants to attend to either features of an item (i.e., in the item condition) or spatial relationships between items (i.e., in the relational condition) that might be subsequently modified during test. At test, participants viewed scenes that were unchanged (i.e., repeated from study), scenes that underwent an "item" modification (an exemplar switch) or a "relational" modification (a location switch), and scenes that had not been presented before. Eye movements were recorded throughout. Results: During study, there were no significant group differences in viewing directed to regions of scenes that might be manipulated at test, suggesting comparable processing of scene details during encoding. However, there was a group difference in explicit recognition accuracy for scenes that underwent a relational change. Marginal group differences in the expression of memory-based viewing effects during test for relational scenes were consistent with this behavioral outcome, particularly when analyses were limited to scenes recognized correctly with high confidence. Group differences were also evident in correlational analyses that examined the association between study phase viewing and recognition accuracy and between performance on the Picture Sequence Memory Test and recognition accuracy. Discussion: Together, our findings suggest differences in the integrity of relational memory representations and/or in the relationships between subcomponents of memory in autism.
RESUMEN
Current United States statistics suggest that autistic individuals will experience high unemployment and underemployment rates throughout their lives. Furthermore, despite the passage of federal legislation to employ young autistic adults in competitive integrated settings, where they work alongside non-disabled workers and earn at least minimum wage, most individuals receiving state services still are placed in day programs or sheltered workshops. Since meaningful employment is the most important determinant of life satisfaction, this failure is a critical societal problem, exerting increasing pressure for systems change. But the news is not all bad. Private sector companies have increased their hiring of disabled workers, producing a growing base of expertise in the recruitment, on-boarding, training, and management of autistic employees. This has led to a growing recognition that autistic individuals can be ideal workers. Autism researchers have advanced the field by investigating these private industry programs as well as conducting efficacy trials of interventions and services that help autistic individuals in the workplace. However, gaps in knowledge persist stemming from the heterogeneity of autistic workers, limited knowledge about those not receiving state services, and a system of federal services that is fragmented, poorly coordinated, difficult to navigate, and over-taxed. Autism researchers can continue to improve outcomes of autistic workers through investigations of the fit between autistic workers, their preferences, and the characteristics of available jobs, and through effectiveness trails of promising employment interventions and services that promote systems change that help break down the barriers to better integration of existing state services and resources in the United States.

Preliminary evidence from the Childhood Joint Attention Rating Scale (C-JARS; Mundy et al., 2017) suggests symptoms related to diminished joint attention and the spontaneous sharing of experience with others can be assessed with a parent-report measure in children and adolescents with autism. This study was designed to expand on the previous study by examining the validity of both a Social Symptom (SS) and a Prosocial (PS) scale of the C-JARS in a study of school-aged autistic children (n = 89) with and without co-occurring intellectual disability (ID), as well as an age matched neurotypical sample (n = 62). Results indicated that both C-JARS scales were sensitive and specific with respect to identifying the diagnostic status of the children. In addition, the PS scale was sensitive to differences in cognitive abilities (IQ) and sex differences in the autism group. These results are consistent with the hypothesis that joint attention and spontaneous sharing of experience symptoms are not only characteristic of preschool children with autism but may also constitute a developmentally continuous dimension of the social phenotype of autism that can be measured in school-aged children.
RESUMEN
Background: We extended our study of trajectories of intellectual development of autistic individuals in early (mean age 3 years; T1), and middle childhood (mean age 5 years, 7 months; T2) into later middle childhood/preadolescence (mean age 11 years, 6 months; T3) in the longitudinal Autism Phenome Project cohort. Participants included 373 autistic children (115 females). Methods: Multivariate latent class growth analysis was used to identify distinct IQ trajectory subgroups. Baseline and developmental course group differences and predictors of trajectory membership were assessed using linear mixed effects models with repeated measures with pairwise testing, multinomial logistic regression models, and sensitivity analyses. Results: We isolated three IQ trajectories between T1 and T3 for autistic youth that were similar to those found in our prior work. These included a group with persistent intellectual disability (ID; 45%), a group with substantial increases in IQ (CHG; 39%), and a group with persistently average or above IQs (P-High; 16%). By T3, the groups did not differ in ADOS-2 calibrated severity scores (CSS), and there were no group differences between Vineland (VABS) communication scores in CHG and P-High. T1-T3 externalizing behaviors declined significantly for CHG, however, there were no significant T3 group differences between internalizing or externalizing symptoms. T1 correlates for CHG and P-High versus ID group membership included higher VABS communication and lower ADOS-2 CSS. A T1 to T2 increase in VABS communication scores and a decline in externalizing predicted CHG versus ID group membership at T3, while T1 to T2 improvement in VABS communication and reduction in ADOS-2 CSS predicted P-High versus ID group membership. Conclusions: Autistic youth exhibit consistent IQ developmental trajectories from early childhood through preadolescence. Factors associated with trajectory group membership may provide clues about prognosis, and the need for treatments that improve adaptive communication and externalizing symptoms.
RESUMEN
Background: There are a few ecologically valid measurements of Daily Living Skills (DLS)-a critical component of adaptive functioning (AF)-for autistic adolescents and young adults. This is particularly important given that DLS predict outcomes as autistic adolescents transition to adulthood. Methods: We pilot-tested the assessment section of two modules of the Computerized Functional Skills Assessment and Training program (CFSAT) in 25 autistic (n = 4 female) and 25 non-autistic (n = 6 female) adolescents and young adults to evaluate preliminary feasibility in an autistic sample. Tasks involved using an ATM and ticket-buying machine. We also assessed AF and DLS with a well-validated self-report questionnaire. We examined group differences in performance and relationships between performance on CFSAT and an existing measure of AF and DLS. We also conducted regression analyses to investigate the associations between age, IQ, executive functioning (EF), and CFSAT task performance. Results: All but one autistic participant were able to complete the CFSAT tasks. Autistic participants made more errors, but did not take longer to complete the task, than non-autistic participants. Performance correlated strongly with self-reported AF generally and DLS specifically. The regression analyses revealed that task performance was associated with EF in the autistic group, but not the non-autistic group. Conclusions: These results provide preliminary support for the use of a new performance-based ecologically valid assessment of DLS in an autistic population. Two CFSAT modules were well-tolerated and detected differences in DLS ability. Strong correlations with an existing measure of AF suggest evidence of construct validity. The EF was associated with CFSAT task performance in autistic individuals. Such a tool could help identify individuals who would benefit from a DLS intervention.
Why is this an important issue?: For autistic adolescents and young adults, one of the most important predictors of success after high school are daily living skills (DLS), which are a component of adaptive functioning (AF), or the ability to operate independently when engaged in day-to-day tasks. However, most of the measures used to assess these abilities are parent- or child-report questionnaires, which may lack objectivity. What was the purpose of this study?: The Computerized Functional Skills Assessment and Training program (CFSAT) is an innovative software program that was designed to teach people how to perform daily tasks that require the use of technology. This study piloted two CFSAT modules in a sample of autistic adolescents and young adults. The researchers wanted to see whether the program could be completed by the autistic participants and whether their performance related to an existing measure of DLS and other cognitive measures known to be related to AF. What did the researchers do?: This study piloted the assessment portion of two CFSAT modules in 25 autistic and 25 non-autistic adolescents and young adults to investigate whether it might be a useful measure of DLS skills in autistic individuals. The assessment portion of the program gives participants tasks to complete on a virtual ATM and Metro Ticket Kiosk and records time to completion and accuracy. Participants also used a questionnaire to self-report DLS and general AF and performed cognitive tasks. What were the results of the study?: All but one autistic participant were able to complete both tasks. The autistic group made more errors but did not take more time to complete the tasks compared with the non-autistic group. Performance on the CFSAT was related to self-reported DLS scores on a questionnaire and to scores on cognitive tasks. What do these findings add to what was already known?: Previous work recommended computer-based DLS programs for autistic individuals. Since our results suggest the CFSAT is a viable computer-based program of DLS for autistic adults, CFSAT could help fill a need for DLS tools that are more applicable to real life than currently available questionnaires. Findings provide preliminary support that the CFSAT assessment measures DLS and could be a promising program to further study. What are potential weaknesses in the study?: Weaknesses of our work include that the measures used in this study only assessed two specific tasks encountered in daily living. Data on participants' real-life experience were not fully collected, so the association between the amount of real-life experience on these tasks and computer task performance will require further study. No data asking whether the tasks studied are useful for autistic adolescents and adults were collected. The study was small and consisted of relatively fewer women, which means that results will need to be replicated in a larger sample. How will these findings help autistic adults now or in the future?: This work could eventually pave the way for interventions that improve DLS (including the training version of the CFSAT) that may be helpful for teaching autistic individuals technology-related functional skills.
RESUMEN
We used parent report data to investigate video game playing, aggression, and social impairment in adolescents with autism spectrum disorder. Parents of autistic adolescents were more likely to report that their child plays video games as a hobby compared to parents of adolescents with typical development and also reported that their children spent more time playing video games. For autistic participants, we found no differences in aggression levels or social impairment when comparing players versus non-players. However, playing video games "more than average," as compared to "average" was associated with greater aggression and greater social impairment on "awareness" and "mannerisms" subscales. Future studies should focus on how type of video game(s) played is associated with these clinically important variables.

BACKGROUND: Intellectual disability affects approximately one third of individuals with autism spectrum disorder (autism). Yet, a major unresolved neurobiological question is what differentiates autistic individuals with and without intellectual disability. Intelligence quotients (IQs) are highly variable during childhood. We previously identified three subgroups of autistic children with different trajectories of intellectual development from early (2-3½ years) to middle childhood (9-12 years): (a) persistently high: individuals whose IQs remained in the normal range; (b) persistently low: individuals whose IQs remained in the range of intellectual disability (IQ < 70); and (c) changers: individuals whose IQs began in the range of intellectual disability but increased to the normal IQ range. The frontoparietal (FPN) and default mode (DMN) networks have established links to intellectual functioning. Here, we tested whether brain regions within the FPN and DMN differed volumetrically between these IQ trajectory groups in early childhood. METHODS: We conducted multivariate distance matrix regression to examine the brain regions within the FPN (11 regions x 2 hemispheres) and the DMN (12 regions x 2 hemispheres) in 48 persistently high (18 female), 108 persistently low (32 female), and 109 changers (39 female) using structural MRI acquired at baseline. FPN and DMN regions were defined using networks identified in Smith et al. (Proc Natl Acad Sci U S A 106:13040-5, 2009). IQ trajectory groups were defined by IQ measurements from up to three time points spanning early to middle childhood (mean age time 1: 3.2 years; time 2: 5.4 years; time 3: 11.3 years). RESULTS: The changers group exhibited volumetric differences in the DMN compared to both the persistently low and persistently high groups at time 1. However, the persistently high group did not differ from the persistently low group, suggesting that DMN structure may be an early predictor for change in IQ trajectory. In contrast, the persistently high group exhibited differences in the FPN compared to both the persistently low and changers groups, suggesting differences related more to concurrent IQ and the absence of intellectual disability. CONCLUSIONS: Within autism, volumetric differences of brain regions within the DMN in early childhood may differentiate individuals with persistently low IQ from those with low IQ that improves through childhood. Structural differences in brain networks between these three IQ-based subgroups highlight distinct neural underpinnings of these autism sub-phenotypes.

This pilot study sought to identify potential markers of improvement from pre-post treatment in response to computerized working memory (WM) training for youth (ages 8-18) with autism spectrum disorder (ASD) and comorbid intellectual disability (ID) in a single arm, pre-post design. Participants included 26 children with ASD and 18 with comorbid ASD and fragile X syndrome (ASD+FXS). Analyses were adjusted for age and IQ. The ASD group demonstrated greater improvement on WM training relative to the ASD+FXS group. Participants improved on WM and far transfer outcomes, however, there were no significant group differences in improvement except for repetitive behavior. Higher hyperactivity/impulsivity ratings predicted lower performance on visuospatial WM. Findings suggest cognitive training may be beneficial for youth with ASD and ID, warranting further exploration.

Altered amygdala development is implicated in the neurobiology of autism, but little is known about the coordinated development of the brain regions directly connected with the amygdala. Here we investigated the volumetric development of an amygdala-connected network, defined as the set of brain regions with monosynaptic connections with the amygdala, in autism from early to middle childhood. A total of 950 longitudinal structural MRI scans were acquired from 282 children (93 female) with autism and 128 children with typical development (61 female) at up to four time points (mean ages: 39, 52, 64, and 137 months, respectively). Volumes from 32 amygdala-connected brain regions were examined using mixed effects multivariate distance matrix regression. The Social Responsiveness Scale-2 was administered to assess degree of autistic traits and social impairments. The amygdala-connected network exhibited persistent diagnostic differences (p values ≤ 0.03) that increased over time (p values ≤ 0.02). These differences were most prominent in autistics with more impacted social functioning at baseline. This pattern was not observed across regions without monosynaptic amygdala connection. We observed qualitative sex differences. In males, the bilateral subgenual anterior cingulate cortices were most affected, while in females the left fusiform and superior temporal gyri were most affected. In conclusion, (1) autism is associated with widespread alterations to the development of brain regions connected with the amygdala, which were associated with autistic social behaviors; and (2) autistic males and females exhibited different patterns of alterations, adding to a growing body of evidence of sex differences in the neurobiology of autism.SIGNIFICANCE STATEMENT Global patterns of development across brain regions with monosynaptic connection to the amygdala differentiate autism from typical development, and are modulated by social functioning in early childhood. Alterations to brain regions within the amygdala-connected network differed in males and females with autism. Results also indicate larger volumetric differences in regions having monosynaptic connection with the amygdala than in regions without monosynaptic connection.

The structure of large-scale intrinsic connectivity networks is atypical in adolescents diagnosed with autism spectrum disorder (ASD or autism). However, the degree to which alterations occur in younger children, and whether these differences vary by sex, is unknown. We utilized structural magnetic resonance imaging (MRI) data from a sex- and age- matched sample of 122 autistic and 122 typically developing (TD) children (2-4 years old) to investigate differences in underlying network structure in preschool-aged autistic children within three large scale intrinsic connectivity networks implicated in ASD: the Socioemotional Salience, Executive Control, and Default Mode Networks. Utilizing structural covariance MRI (scMRI), we report network-level differences in autistic versus TD children, and further report preliminary findings of sex-dependent differences within network topology.

BACKGROUND: The amygdala is widely implicated in both anxiety and autism spectrum disorder. However, no studies have investigated the relationship between co-occurring anxiety and longitudinal amygdala development in autism. Here, the authors characterize amygdala development across childhood in autistic children with and without traditional DSM forms of anxiety and anxieties distinctly related to autism. METHODS: Longitudinal magnetic resonance imaging scans were acquired at up to four time points for 71 autistic and 55 typically developing (TD) children (â¼2.5-12 years, 411 time points). Traditional DSM anxiety and anxieties distinctly related to autism were assessed at study time 4 (â¼8-12 years) using a diagnostic interview tailored to autism: the Anxiety Disorders Interview Schedule-IV with the Autism Spectrum Addendum. Mixed-effects models were used to test group differences at study time 1 (3.18 years) and time 4 (11.36 years) and developmental differences (age-by-group interactions) in right and left amygdala volume between autistic children with and without DSM or autism-distinct anxieties and TD children. RESULTS: Autistic children with DSM anxiety had significantly larger right amygdala volumes than TD children at both study time 1 (5.10% increase) and time 4 (6.11% increase). Autistic children with autism-distinct anxieties had significantly slower right amygdala growth than TD, autism-no anxiety, and autism-DSM anxiety groups and smaller right amygdala volumes at time 4 than the autism-no anxiety (-8.13% decrease) and autism-DSM anxiety (-12.05% decrease) groups. CONCLUSIONS: Disparate amygdala volumes and developmental trajectories between DSM and autism-distinct forms of anxiety suggest different biological underpinnings for these common, co-occurring conditions in autism.

Intranasal oxytocin (IN OXT) administration has been proposed as a pharmacological treatment for a range of biomedical conditions including neurodevelopmental disorders. However, studies evaluating the potential long-lasting effects of chronic IN OXT during development are still scarce. Here we conducted a follow-up study of a cohort of adult titi monkeys that received intranasal oxytocin 0.8 IU/kg (n = 15) or saline (n = 14) daily for six months during their juvenile period (12 to 18 months of age), with the goal of evaluating the potential long-lasting behavioral and neural effects one year post-treatment. Subjects were paired with an opposite-sex mate at 30 months of age (one year post-treatment). We examined pair affiliative behavior in the home cage during the first four months and tested for behavioral components of pair bonding at one week and four months post-pairing. We assessed long-term changes in brain glucose uptake using 18FDG positron emission tomography (PET) scans. Our results showed that OXT-treated animals were more affiliative across a number of measures, including tail twining, compared to SAL treated subjects (tail twining is considered the "highest" type of affiliation in titi monkeys). Neuroimaging showed no treatment differences in glucose uptake between SAL and OXT-treated animals; however, females showed higher glucose uptake in whole brain at 23 months, and in both the whole brain and the social salience network at 33 months of age compared to males. Our results suggest that chronic IN OXT administration during development can have long-term effects on adult social behavior.

An individual's autism symptom severity level can change across childhood. The prevalence and direction of change, however, are still not well understood. Nor are the characteristics of children that experience change. Symptom severity trajectories were evaluated from early to middle childhood (approximately ages 3-11) for 182 autistic children. Symptom severity change was evaluated using individual change scores and the Reliable Change Index. Fifty-one percent of participants experienced symptom severity change: 27% of children decreased in severity, 24% increased and 49% were stable. Symptom severity decreases were more common during early childhood. Severity increases occurred at both early and middle childhood but increase in social affect severity was especially prominent during middle childhood. Most children experienced significant change during only one period and remained stable during the other. Girls decreased more and increased less in symptom severity than boys. Children that increased in severity decreased in adaptive functioning across childhood. Exploratory analyses indicated that a decrease in severity was associated with higher parental education level and older parental age at the time of the child's birth. Conversely, increase in autism severity was associated with lower parental education level and younger parental age at the child's birth. These findings extend recent observations that symptom severity change is more likely than previously appreciated. An understanding of the role of both biological and sociodemographic factors in determining a child's symptom trajectory may factor into future decisions on allocation and type of interventions distributed to young autistic children. LAY SUMMARY: We studied whether a child's autism severity changed from initial diagnosis until middle childhood (ages 3-11). We found that 27% of the children decreased in severity, 24% increased and the rest stayed the same. Symptom severity decreases were more common during early childhood while severity increases were more prominent during middle childhood. We also found that girls were more likely to decrease than boys. Whether a child decreased or increased is related, in part, to parental characteristics.

Background: African American/Black (AA/B) young adults with diagnoses of autism spectrum disorders rarely are studied in a way that acknowledges both their racial identity and their autism diagnosis. Little is known about intersectional oppression in the lives of these young adults. Early adulthood is a time when a young people of color may come to terms with a society that may not treat them fairly and equally due to their race. Autistic AA/B young adults may be even more vulnerable to stress and psychological disempowerment due to the added impact of negative experiences of being Black and having an autism diagnosis. Methods: Thirty-two autistic and 30 non-autistic AA/B young adults took part in an online survey examining risk factors of everyday discrimination, perceived stress and potential protective factors of psychological empowerment, and Black identity. Differences in score measures for the autistic and non-autistic samples were examined along with the predictors of perceived stress assessed. Frequencies of intersectional discrimination experiences were also examined. Results: Autistic AA/B participants reported significantly less everyday discriminatory experiences than non-autistic AA/B participants, whereas perceived stress was not significantly different between the two groups. The majority of non-autistic AA/B participants endorsed race as their prime source of experiences of discrimination, whereas autistic AA/B participants also cited being autistic as a major contributor to reports of discrimination. Although the autistic group had significantly lower reports of self-determination, they reported higher on the Black identity, private regard scale, pertaining to feelings about group membership, which can be considered a protective factor. There is heterogeneity in reasons for discriminatory experiences for autistic AA/B young adults whereby some of the participants (12%-30%) endorsed race + disability as dual reasons for experiencing regular discrimination. Conclusions: Mental health clinicians and other direct service providers working with autistic AA/B young adults should understand that intersecting identities of race and disability may be at play when they are working with these individuals, and that treatment should consider these factors.
Why is this an important issue?: The experiences of autistic African American/Black adults need more attention. There is not much research looking at intersecting identities of race and disability. What was the purpose of this study?: The purpose of this study was to examine race + disability intersectionality in discrimination experiences and to examine how risk factors and protective factors vary between autistic and non-autistic African American/Black young adults. What did the researchers do?: The researchers conducted an online study comparing the experiences of autistic and non-autistic young adults who identified as African American/Black. Thirty-two autistic and 30 non-autistic African American/Black young adults took part in the study looking at experiences of discrimination, stress, Black identity, and self-determination. What were the results of the study?: Autistic African American/Black participants reported fewer everyday discriminatory experiences than non-autistic African American/Black participants, but perceived stress was not different between the two groups. Most of the non-autistic African American/Black participants listed race as their prime source of discrimination experiences, whereas autistic African American/Black participants also cited being autistic as a major contributor to reports of discrimination. Reasons for discriminatory experiences for autistic African American/Black young adults are varied, with up to 30% relating to experiences of discrimination being dual issues of race and disability. What do these findings add to what was already known?: There is a lot of research on the experiences of African African/Black people facing social adversities due to race. This study adds to what is known by shedding light on discrimination experiences of autistic African American/Black young adults. The findings show the need for both societal change and trauma-informed practices with autistic individuals who are negatively impacted by a society that views them through a racialized lens. What are potential weaknesses in the study?: This study is not reflective of all autistic African American/Black people. Individuals who took part in the study may have self-selected due to interest in the topic. In addition, gender was not taken into account for this study. How will these findings help autistic adults now or in the future?: Knowing more about autistic African American/Black young adults' experiences can help inform advocacy to reduce discrimination and interventions to promote resiliency. The results of this study also highlight the importance of studying intersectionality in disability research. More research is needed about the experiences of autistic African American/Black young adults.
