Titre : Academic learning challenges and links to vocational outcomes in young autistic adults Type de document : Texte imprimé et/ou numérique Auteurs : Diego ARAGON-GUEVARA, Auteur ; Goldie A. MCQUAID, Auteur ; Gregory L. WALLACE, Auteur ; Nancy Raitano LEE, Auteur Article en page(s) : p.3143-3155 Langues : Anglais (eng) Mots-clés : adult autism spectrum disorders cognition (attention learning memory) vocational/labor force participation Index. décimale : PER Périodiques Résumé : Obtaining and maintaining employment can be a challenge for autistic adults and learning challenges may be related to vocational outcomes in this population. The present study sought to evaluate the Learning Needs Screening Tool to identify autistic job seekers who may benefit from additional services to obtain employment. A total of 401 autistic adults participated in this study. Internal consistency of Learning Needs Screening Tool items was evaluated. A principal component analysis was then completed to understand the measure?s factor structure and evaluations of external validity were completed. Evaluation of the screening items of the Learning Needs Screening Tool revealed high internal consistency. Three factors (Orthography, Arithmetic, and Retrospective Learning and Service Receipt) emerged. Overall, 56% of the sample screened positive on the Learning Needs Screening Tool, indicating a history of learning challenges. Analysis of history of special education receipt and vocational outcomes showed strong external validity for the measure. Results support the utility of the Learning Needs Screening Tool as a possible screening tool to evaluate learning challenges in autistic job seekers. As those who screened positive were more likely to have no vocational/educational activities, knowledge of retrospective learning needs may help vocational counselors identify autistic adults who need greater supports when seeking and obtaining jobs. Lay abstract Finding a job can be hard for autistic adults. No studies have been completed that look into whether having difficulties learning and troubles finding a job are related in this population. The current study did so by evaluating the Learning Needs Screening Tool, a measure of learning challenges used in vocational rehabilitation settings, or places meant to help people find work. A total of 401 autistic adults completed this study online. Specifically, the study evaluated (a) the characteristics of the Learning Needs Screening Tool, including the relationships between questions that ask about similar learning challenges, and (b) the ability of the measure to relate to real-world outcomes that are associated with learning difficulties, namely prior special education receipt and difficulties finding a job. Evaluation of the questions asked on the Learning Needs Screening Tool revealed that they were highly related and that learning difficulties fell into different categories. Fifty-six percent of the people in the study showed learning challenges on the measure. People who were identified as having learning difficulties on the Learning Needs Screening Tool had higher rates of receiving special education services in the past and lower rates of current employment. These results suggest that the Learning Needs Screening Tool may help to identify autistic job seekers who have learning difficulties and may have more challenges finding a job.

Titre : Adaptive Behavior in Youth with Autism Spectrum Disorder: The Role of Flexibility Type de document : Texte imprimé et/ou numérique Auteurs : Jennifer R. BERTOLLO, Auteur ; John F. STRANG, Auteur ; Laura G. ANTHONY, Auteur ; Lauren KENWORTHY, Auteur ; Gregory L. WALLACE, Auteur ; Benjamin E YERYS, Auteur Article en page(s) : p.42-50 Langues : Anglais (eng) Mots-clés : Adaptive behavior Autism spectrum disorder Executive function Flexibility Index. décimale : PER Périodiques Résumé : Cognitive and behavioral flexibility are important predictors of adaptive behavior in school-age autistic youth. While prior research has utilized broad measures of flexibility, the current study uses the multi-dimensional Flexibility Scale-Revised to examine which specific flexibility skills relate to adaptive functioning. Through parent-report measures on 216 autistic youth, flexibility explained 22.2% of variance in adaptive socialization skills (p < 0.001). Specifically, Social Flexibility accounted for significant variance in adaptive socialization skills, while Transitions/Change approached significance. In exploratory analyses, flexibility explained 11.5% of variance in Communication skills (p < 0.001). This pattern remained after controlling for co-occurring ADHD symptoms. The current study helps to refine the relationship between flexibility and adaptive behavior, which may ultimately help to inform more targeted interventions.

Titre : Adaptive Behavior Ratings Correlate With Symptomatology and IQ Among Individuals With High-Functioning Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Lauren E. KENWORTHY, Auteur ; Gregory L. WALLACE, Auteur ; Alex MARTIN, Auteur ; Laura CASE, Auteur ; Madeline B. HARMS, Auteur Année de publication : 2010 Article en page(s) : p.416-423 Langues : Anglais (eng) Mots-clés : Autism Adaptive-behavior Social-skills IQ Symptomatology Asperger’s-syndrome Index. décimale : PER Périodiques Résumé : Caregiver report on the Adaptive Behavior Assessment System-II (ABAS) for 40 high-functioning individuals with Autism Spectrum Disorders (ASD) and 30 typically developing (TD) individuals matched for age, IQ, and sex ratio revealed global adaptive behavior deficits in ASD, with social skills impairments particularly prominent. Within the ASD group, adaptive communication skills were positively related to IQ while global adaptive functioning was negatively associated with autism symptomatology. Autistic behavior ratings related negatively to ABAS scores in the TD but not the ASD group. This investigation demonstrates: the utility of an adaptive functioning checklist for capturing impairments, even in high-functioning individuals with ASD; and that a relationship between social abilities and autism exists independently of intelligence.

Index. décimale : PER Périodiques Résumé : Executive functions are often impaired in autistic people and relate to important outcomes such as mental health, success in school and work, and quality of life. Evaluating executive functions helps autistic people, clinicians, and families identify targets for external supports and skill building. Youth self-report of executive function has not been studied, yet we know that self-report from autistic youth is key to understanding other cognitive/behavioral phenomena in autism such as anxiety, obsessions/compulsions, sensory sensitivities, and repetitive behaviors. We investigated self- and parent-report of executive function problems in 197 autistic youth without intellectual disability (ages 11-18?years), including the magnitude and profiles of executive function problems autistic youth report across subdomains of executive function. We compared autistic self-report with that of 114 youth with attention deficit hyperactivity disorder without intellectual disability and 197 neurotypical youth. We found that autistic youth report significant executive function problems compared to neurotypical youth and a distinctive profile of challenges in comparison to attention deficit hyperactivity disorder youth. Parents and their autistic children diverged regarding the magnitude of the youth's executive function difficulties, but both identify inflexibility as the most impaired executive function subdomain. Autistic youth and their parents were somewhat more concordant in their report of executive function problems than youth with attention deficit hyperactivity disorder and their parents, but only showed moderate concordance at best. These findings elevate the importance of asking autistic youth directly about their executive functioning when engaging them in assessment and intervention, or researching executive functions in autism.

Titre : Aging and autism spectrum disorder: Evidence from the broad autism phenotype Type de document : Texte imprimé et/ou numérique Auteurs : Gregory L.

CHARLTON, Auteur Article en page(s) : p.1294-1303 Langues : Anglais (eng) Mots-clés : broad autism phenotype autism aging older adulthood executive function anxiety depression social support Index. décimale : PER Périodiques Résumé : This study investigated for the first time the broad autism phenotype (BAP) in the context of older adulthood and its associations with real-world executive function, social support, and both depression and anxiety symptomatology. Based on self-ratings of autistic traits, 66 older adults (60+ years old, range?=?61–88) were split into BAP (n?=?20) and control (n?=?46) groups. Individuals in the BAP group, even after controlling for age, education level, sex, and health problems, exhibited more real-world executive function problems in multiple domains, reported lower levels of social support, and self-rated increased depression and anxiety symptomatology compared to the control group. Regression analysis revealed that level of social support was the strongest predictor of BAP traits across both groups, although real-world executive function problems and depression symptomatology were also significant predictors. Moreover, when predicting anxiety and depression symptomatology, BAP traits were the strongest predictors above and beyond the effects of demographic factors, real-world executive function problems, and social support levels. These findings suggest that the BAP in older adulthood imparts additional risks to areas of functioning that are known to be crucial to aging-related outcomes in the context of typical development. These results might in turn inform aging in autism spectrum disorder, which has been largely unexplored to date.
