Sex differences in parent-reported executive functioning and adaptive behavior in children and young adults with autism spectrum disorder / Emily I. WHITE in Autism Research, 10-10 (October 2017)
[article]
Titre : Sex differences in parent-reported executive functioning and adaptive behavior in children and young adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Emily I. WHITE, Auteur ; Gregory L. WALLACE, Auteur ; Julia BASCOM, Auteur ; Anna Chelsea ARMOUR, Auteur ; Kelly REGISTER-BROWN, Auteur ; Haroon S. POPAL, Auteur ; Allison B. RATTO, Auteur ; Alex MARTIN, Auteur ; Lauren KENWORTHY, Auteur Article en page(s) : p.1653-1662 Langues : Anglais (eng) Mots-clés : autism spectrum sex differences executive function adaptive functioning Index. décimale : PER Périodiques Résumé : This study is the largest to date examining executive function and adaptive skills in females with autism spectrum disorder (ASD). Its primary aim was to utilize parent ratings of real-world executive functioning and adaptive behavior to better understand whether females with ASD differ from males with ASD in these areas of everyday functioning. We compared 79 females with ASD to 158 males with ASD (ages 7–18) who were statistically matched on age, IQ, and level of ADHD or ASD traits. All participants were assessed using the Behavior Rating Inventory of Executive Function (BRIEF) and a subset (56 females and 130 males) also received the Vineland Adaptive Behavior Scales (VABS). Females were rated by parents as having greater problems with executive function on the BRIEF. Parents also rated females as exhibiting more difficulties than males on the Daily Living Skills domain of the VABS. There was a correlation between increased global EF difficulty and decreased adaptive ability in both males and females. Our results indicate relative weaknesses for females compared to males diagnosed with ASD on executive function and daily living skills. These differences occur in the absence of sex differences in our sample in age, IQ, clinician ratings of core ASD symptomatology, parent ratings of ADHD symptoms, and parent-reported social and communication adaptive skills on the VABS. These findings indicate specific liabilities in real world EF and daily living skills for females with ASD and have important implications for targeting their treatments.

CHARLTON in Autism, 27-1 (January 2023)
[article]
Titre : Social support and links to quality of life among middle-aged and older autistic adults Type de document : Texte imprimé et/ou numérique Auteurs : Rebecca A. CHARLTON, Auteur ; Goldie A. MCQUAID, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.92-104 Langues : Anglais (eng) Mots-clés : adults autism spectrum disorders gerontautism quality of life Index. décimale : PER Périodiques Résumé : Social support has a positive impact on quality of life (QoL) in neurotypical older adults and young autistic adults, but the association for older autistic adults is unclear. Autistic adults (n=388; mean age=40-83 years) were recruited via Simons Powering Autism Research for Knowledge (SPARK) Research Match. Participants completed questionnaires online querying demographic information, depression, and anxiety symptomatology, QoL (physical, psychological, social, environmental, and autism-specific) and social support (instrumental, subjective, and social interactions). Regression analyses examined whether different aspects of social support contributed to models explaining each domain of QoL. Models explaining QoL were significant. Subjective social support significantly contributed to the models for all aspects of QoL; social interactions contributed to the models for Physical and Psychological QoL, whereas instrumental support contributed to models for social, environmental and autism-specific QoL. Social support is an important contributor to the QoL of middle-aged and older autistic adults, after accounting for demographic factors and depression. Further studies are required to understand whether age-related changes in social support and QoL are the same for autistic as non-autistic older adults in order to identify and implement appropriate support. Lay abstract Social support can take many forms, such as practical help, time spent socially with others, or the satisfaction with personal relationships. Social support is known to affect quality of life (QoL) in both non-autistic older and autistic young adults. QoL reflects how satisfied an individual is with their life either overall or in a certain area. We know little about middle-aged and older autistic adults’ experiences of social support or QoL. In this study, 388 adults aged 40-83 years old, completed online questionnaires asking about background such as age and sex, depression and anxiety symptoms, QoL (physical, psychological, social, environmental, and autism-specific), and different types of social support. Even after taking into account background, depression, and anxiety, social support was important for individuals’ QoL. To our knowledge this is the first paper to examine the relationship between social support and QoL in middle-aged and older autistic adults. Improving social support may have a significant impact on the QoL of older autistic adults. Future studies should examine whether age-related changes in social support (size, content, and arrangement of social networks) that are common in non-autistic aging, also occur among older autistic adults.

NADEAU, Auteur ; E. RICHARD, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.987-994 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Child Diet Feeding Behavior Food Preferences Humans Hyperphagia Autism Eating Flexibility Health Picky Selective Index. décimale : PER Périodiques Résumé : Based on parent questionnaires, we demonstrate the presence of an eating pattern among children with autism spectrum disorder (ASD) that is characterized by both food selectivity and eating in the absence of hunger. Children with ASD were categorized as engaging in eating patterns of selective overeating, selective eating only, overeating only, or typical eating. Group differences were found in the areas of diet composition, body mass index, and behavioral flexibility. Both the selective overeating group and selective eating only group were prone to favor calorie-dense, nutrient-deficient diets as compared to other groups. Eating groups also presented with differing profiles of everyday behavioral flexibility. These results suggest that selective overeating in ASD may present unique challenges and require tailored interventions.

However, existing informant reports do not densely sample cognitive aspects of flexibility; the Flexibility Scale (FS) was developed to address this gap. This study investigates the validity of the FS in 221 youth with ASD and 57 typically developing children. Exploratory factor analysis indicates a five-factor scale: Routines/rituals, transitions/change, special interests, social flexibility, and generativity. The FS demonstrated convergent and divergent validity with comparative domains of function in other measures, save for the Generativity factor. The FS discriminated participants with ASD and controls. Thus, this study suggests the FS may be a viable, comprehensive measure of flexibility in everyday settings.

Titre : The Gap Between Adaptive Behavior and Intelligence in Autism Persists into Young Adulthood and is Linked to Psychiatric Co-morbidities Type de document : Texte imprimé et/ou numérique Auteurs : Catherine K. KRAPER, Auteur ; Lauren KENWORTHY, Auteur ; Haroon POPAL, Auteur ; Alex MARTIN, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.3007-3017 Langues : Anglais (eng) Mots-clés : Adaptive functioning Adulthood Autism spectrum disorder ;Psychopathology IQ Outcome Index. décimale : PER Périodiques Résumé : For individuals with autism spectrum disorder (ASD), long-term outcomes have been troubling, and intact IQ has not been shown to be protective. Nevertheless, relatively little research into adaptive functioning among adults with ASD has been completed to date. Therefore, both adaptive functioning and comorbid psychopathology were assessed among 52 adults with ASD without intellectual disability (ID). Adaptive functioning was found to substantially lag behind IQ, and socialization was a particular weakness. Comorbid psychopathology was significantly correlated with the size of IQ-adaptive functioning discrepancy. These findings emphasize key intervention targets of both adaptive skill and psychopathology for transition-age youth and young adults with ASD, as well as the need for ongoing monitoring of anxiety and depression symptoms during this developmental window.
