Longitudinal Examination of Adaptive Behavior in Autism Spectrum Disorders: Influence of Executive Function / Cara E. PUGLIESE in Journal of Autism and Developmental Disorders, 46-2 (February 2016)
[article]
Titre : Longitudinal Examination of Adaptive Behavior in Autism Spectrum Disorders: Influence of Executive Function Type de document : Texte imprimé et/ou numérique Auteurs : Cara E. PUGLIESE, Auteur ; Laura GUTERMUTH ANTHONY, Auteur ; John F. STRANG, Auteur ; Katerina DUDLEY, Auteur ; Gregory L. WALLACE, Auteur ; Daniel Q. NAIMAN, Auteur ; Lauren KENWORTHY, Auteur Année de publication : 2016 Article en page(s) : p.467-477 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Adaptive behavior Executive function Cognitive ability Longitudinal Index. décimale : PER Périodiques Résumé : This study characterizes longitudinal change in adaptive behavior in 64 children and adolescents with autism spectrum disorder (ASD) without intellectual disability evaluated on multiple occasions, and examines whether prior estimate of executive function (EF) problems predicts future adaptive behavior scores. Compared to standardized estimates for their developmental stage, adaptive behavior in most participants was impaired and did not improve over time. Prior EF predicted later adaptive behavior in daily living skills and socialization domains after controlling for age and IQ. Self-monitoring behaviors robustly predicted later adaptive behavior in all domains (d = 0.60–0.94). Results support targeting treatment of adaptive skills in ASD, as well as the importance of assessing for EF problems that may contribute to adaptive behavior difficulties.

Titre : Measuring flexibility in autistic adults: Exploring the factor structure of the flexibility scale self report Type de document : Texte imprimé et/ou numérique Auteurs : Goldie A. MCQUAID, Auteur ; Benjamin E. YERYS, Auteur ; John F. STRANG, Auteur ; Laura G. ANTHONY, Auteur ; Lauren KENWORTHY, Auteur ; Nancy R. LEE, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.2208-2219 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Cognitive flexibility differences are common for autistic individuals and have an impact on a range of clinical outcomes. However, there is currently a lack of well validated measurement tools to assess flexibility in adulthood. The Flexibility Scale was originally designed as a parent-report measure of real-world flexibility challenges in youth. The original Flexibility Scale provides a total score and five subscales: Routines and Rituals, Transitions and Change, Special Interests, Social Flexibility, and Generativity. In this study, we evaluate the factorial validity of the Flexibility Scale as a self-report (Flexibility Scale Self Report) measure of cognitive flexibility, adapted from the original Flexibility Scale, for use by autistic adults. This study includes both a primary sample (n=813; mean age=40.3; 59% female) and an independently recruited replication sample (n=120; mean age=32.8; 74% female) of individuals who completed the Flexibility Scale Self Report. The analysis consisted of an initial confirmatory factor analysis (CFA) of the original Flexibility Scale structure, followed by exploratory factor analysis (EFA) and factor optimization within a structural equation modeling framework to identify the optimal structure for the questionnaire in adults. The identified structure was then replicated through CFA in the replication sample. Our results indicate an alternative optimal scale structure from the original Flexibility Scale, which includes fewer items, and only three (Routines/Rituals, Transitions and Change, Special Interests) of the five subscales contributing to the flexibility total score. Comparisons revealed no structural differences within the scale based on sex assigned at birth. Here the Generativity and Social Flexibility scales are treated as independent but related scales. The implications for measurement of cognitive flexibility in clinical and research settings, as well as theoretical underpinnings are discussed.

[article]
Titre : Parent-child concordance on the Pubertal Development Scale in typically developing and autistic youth Type de document : Texte imprimé et/ou numérique Auteurs : Ann CLAWSON, Auteur ; John F. STRANG, Auteur ; Gregory L. WALLACE, Auteur ; Veronica GOMEZ-LOBO, Auteur ; Allison JACK, Auteur ; Sara J. WEBB, Auteur ; Kevin A. PELPHREY, Auteur Article en page(s) : 101610 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD) Puberty Pubertal Development Scale Index. décimale : PER Périodiques Résumé : Background Characterizing puberty in autism spectrum disorder (ASD) is critical given the direct impacts of pubertal progression on neural, cognitive, and physical maturation. Limited information is available about the utility and parent-child concordance of the self-report and parent-report Pubertal Development Scale (PDS) in ASD, an economical and easily administered measure. Method The primary aim of this study was to examine the concordance between self-report and parent-report PDS ratings in autistic males and females ages 8–17y compared to typically developing (TD) youth, including using the PDS to derive informant-based estimates of adrenal and gonadal development. We hypothesized that there would be greater parent-youth discrepancies in pubertal ratings among autistic males. Our second aim was exploratory; we examined whether individual characteristics impact PDS concordance and hypothesized that lower intellectual and adaptive skills, higher autistic traits, and reduced self-awareness/monitoring would correlate with lower concordance. Results There were no significant diagnostic group differences in parent-youth concordance for overall PDS scores among males and females. Autistic males had significantly lower inter-item agreement with their parents than TD males and had lower agreement for both adrenal and gonadal aspects of pubertal maturation (adrenal ??=?.48; gonadal ??=?.55). Conclusions The PDS is a feasible measure in ASD. Greater parent-youth discrepancies in autistic males may be due to reduced parental awareness or reduced insight into pubertal maturation among autistic males. Future research is needed to further elucidate individual and/or environmental characteristics that influence youth- and parent-reported PDS scores, including differences in self-perception and insight.

Studies of monozygotic and dyzygotic twins during this developmental period allow exploration of genetic and non-genetic influences on these developmental trajectories.
Method: Magnetic resonance imaging brain scans were acquired on a pediatric sample of 90 monozygotic twin pairs, 38 same-sex dyzygotic twin pairs, and 158 unrelated typically developing singletons. Structural equation modeling was used to estimate the additive genetic, common environment, and unique environment effects, as well as age by heritability interactions, on measures of brain volumes from these images.
Results: Consistent with previous adult studies, additive genetic effects accounted for a substantial portion of variability in nearly all brain regions with the notable exception of the cerebellum. Significant age by heritability interactions were observed with gray matter volumes showing a reduction in heritability with increasing age, while white matter volume heritability increased with greater age.
Conclusion: Understanding the relative contributions of genetic and nongenetic factors on developmental brain trajectories may have implications for better understanding brain-based disorders and typical cognitive development.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2006.01676.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=788

MCQUAID, Auteur ; Lauren BISHOP, Auteur ; Nancy Raitano LEE, Auteur ; Gregory L. WALLACE, Auteur Article en page(s) : p.757-771 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Poor sleep can have a significant impact on physical health and well-being. Sleep problems are common among autistic children, but less is known about sleep across the autistic adult lifespan. Autistic adults (n = 730, aged 18-78?years) were recruited via Simons Powering Autism Research for Knowledge Research Match. Participants completed online surveys asking about demographics, health problems, social support, symptoms of anxiety and depression, and overall and specific aspects of sleep quality. Regression analyses explored the variables associated with sleep quality. Physical health, assigned female sex at birth and self-reported anxiety symptoms significantly contributed to models for all aspects of sleep. Perceived stress contributed to models of overall and subjective sleep quality, and daytime dysfunction. Depression symptoms did not contribute significantly to any of the models of sleep quality. However, utilizing government support mechanisms (such as social security) contributed to the model of sleep efficiency. Age contributed little to models of sleep quality, whereas perceived stress and psychotropic medication use contributed to some but not all aspects of sleep. Sleep quality is poor for autistic people across the adult lifespan. Given known impacts of poor sleep on health, cognition and quality of life, attention should be paid to sleep and its possible everyday effects for autistic people of all ages.
