An Evaluation of a Social Skills Intervention for Adults with Autism Spectrum Disorder and Intellectual Disabilities preparing for Employment in Ireland: A Pilot Study / E. WALSH in Journal of Autism and Developmental Disorders, 48-5 (May 2018)

Titre : An Evaluation of a Social Skills Intervention for Adults with Autism Spectrum Disorder and Intellectual Disabilities preparing for Employment in Ireland: A Pilot Study Type de document : Texte imprimé et/ou numérique Auteurs : E. WALSH, Auteur ; J. HOLLOWAY, Auteur ; H. LYDON, Auteur Article en page(s) : p.1727-1741 Langues : Anglais (eng) Mots-clés : Adults Autism spectrum disorder Employment Intellectual disability Social communication skills Vocational skills Index. décimale : PER Périodiques Résumé : Individuals with autism spectrum disorder (ASD) are faced with significant barriers relating to employment opportunities and workplace participation. This study evaluated the effectiveness of the Walker social skills curriculum: the ACCESS program and video modeling to increase social communication skills necessary for workplace inclusion. Participants attended two sessions (i.e., 3 h) per week across a period of 20 weeks. A multiple-probe design was used to demonstrate social skills outcomes across three broad curricular areas (i.e., peer-related, adult-related, and self-related social skills). Pre-and post-intervention standardized assessments were also taken. Results showed significant increases in target social skills and a significant decrease in problem behaviors following intervention. Evidence of maintenance and generalization were also demonstrated. Implications for practice and research are discussed.

Titre : The effects of intranasal oxytocin on reward circuitry responses in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : R. K. GREENE, Auteur ; M. SPANOS, Auteur ; C. ALDERMAN, Auteur ; E. WALSH, Auteur ; Joshua BIZZELL, Auteur ; M. G. MOSNER, Auteur ; J. L. KINARD, Auteur ; G. D. STUBER, Auteur ; Tara CHANDRASEKHAR, Auteur ; L. C.

Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Oxytocin Reward fMRI Index. décimale : PER Périodiques Résumé : BACKGROUND: Intranasal oxytocin (OT) has been shown to improve social communication functioning of individuals with autism spectrum disorder (ASD) and, thus, has received considerable interest as a potential ASD therapeutic agent. Although preclinical research indicates that OT modulates the functional output of the mesocorticolimbic dopamine system that processes rewards, no clinical brain imaging study to date has examined the effects of OT on this system using a reward processing paradigm. To address this, we used an incentive delay task to examine the effects of a single dose of intranasal OT, versus placebo (PLC), on neural responses to social and nonsocial rewards in children with ASD. METHODS: In this placebo-controlled double-blind study, 28 children and adolescents with ASD (age: M = 13.43 years, SD = 2.36) completed two fMRI scans, one after intranasal OT administration and one after PLC administration. During both scanning sessions, participants completed social and nonsocial incentive delay tasks. Task-based neural activation and connectivity were examined to assess the impact of OT relative to PLC on mesocorticolimbic brain responses to social and nonsocial reward anticipation and outcomes. RESULTS: Central analyses compared the OT and PLC conditions. During nonsocial reward anticipation, there was greater activation in the right nucleus accumbens (NAcc), left anterior cingulate cortex (ACC), bilateral orbital frontal cortex (OFC), left superior frontal cortex, and right frontal pole (FP) during the OT condition relative to PLC. Alternatively, during social reward anticipation and outcomes, there were no significant increases in brain activation during the OT condition relative to PLC. A Treatment Group x Reward Condition interaction revealed relatively greater activation in the right NAcc, right caudate nucleus, left ACC, and right OFC during nonsocial relative to social reward anticipation during the OT condition relative to PLC. Additionally, these analyses revealed greater activation during nonsocial reward outcomes during the OT condition relative to PLC in the right OFC and left FP. Finally, functional connectivity analyses generally revealed changes in frontostriatal connections during the OT condition relative to PLC in response to nonsocial, but not social, rewards. CONCLUSIONS: The effects of intranasal OT administration on mesocorticolimbic brain systems that process rewards in ASD were observable primarily during the processing of nonsocial incentive salience stimuli. These findings have implications for understanding the effects of OT on neural systems that process rewards, as well as for experimental trials of novel ASD treatments developed to ameliorate social communication impairments in ASD.
