The Flexible Item Selection Task (FIST) differs from previous cognitive flexibility tasks in ASD research by giving children an abstract, ambiguous rule to switch. The ASD group (N = 22; Mean age = 8.28 years, SD = 1.52) achieved a lower shift percentage than the typically developing verbal mental-age control group (N = 22; Mean age = 6.26 years, SD = 0.82). There was a significant positive correlation between verbal mental age and shift percentage for children with ASD. Group differences on the FIST converge and extend prior evidence documenting an impaired ability to adapt rapidly to changes in task demands for individuals with ASD.

Children's vagal regulatory capacity predicts attenuated sympathetic stress reactivity in a socially supportive context: Evidence for a protective effect of the vagal system / Brian C. WOLFF in Development and Psychopathology, 24-2 (May 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-2 (May 2012) . - p.677-689 Titre : Children's vagal regulatory capacity predicts attenuated sympathetic stress reactivity in a socially supportive context: Evidence for a protective effect of the vagal system Type de document : texte imprimé Auteurs : Brian C. WOLFF, Auteur ; Martha E. WADSWORTH, Auteur ; Frank H. WILHELM, Auteur ; Iris B. MAUSS, Auteur Année de publication : 2012 Article en page(s) : p.677-689 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Social support and vagal regulatory capacity (VRC), an index of flexible vagal responses during various types of stress, are linked to attenuated stress responding and positive health outcomes. Guided by the polyvagal perspective, we tested whether children's VRC is associated with attenuated sympathetic nervous system (SNS) stress reactivity in socially supportive conditions. Sixty-one 4- to 5-year-old children living in poverty underwent two standardized laboratory stress induction procedures. Cardiac vagal reactivity (respiratory sinus arrhythmia) to a first set of stressors (social, cognitive, physical, and emotional) indexed VRC. During a second set of stressors, participants were randomly assigned to a supportive or nonsupportive social context, and cardiac sympathetic reactivity (preejection period) was assessed. We hypothesized VRC would predict lower SNS stress reactivity, but only in the socially supportive context. Children with high VRC showed attenuated SNS stress reactivity in the socially supportive context compared to children with high VRC in the nonsupportive context and children with low VRC in either context. Individual differences in VRC predict attenuated SNS stress reactivity in socially supportive conditions. Understanding how social support and VRC jointly mitigate SNS stress reactivity may further efforts to prevent negative health outcomes. Implications for biological sensitivity to context and differential susceptibility theories are discussed.

Telehealth delivery of cognitive-behavioral intervention to youth with autism spectrum disorder and anxiety: A pilot study / Susan HEPBURN in Autism, 20-2 (February 2016)  

Public ISBD [article]  inAutism > 20-2 (February 2016) . - p.207-218 Titre : Telehealth delivery of cognitive-behavioral intervention to youth with autism spectrum disorder and anxiety: A pilot study Type de document : texte imprimé Auteurs : Susan HEPBURN, Auteur ; Audrey BLAKELEY-SMITH, Auteur ; Brian WOLFF, Auteur ; Judy REAVEN, Auteur Article en page(s) : p.207-218 Langues : Anglais (eng) Mots-clés : autism  co-occurring anxiety  intervention  feasibility  telehealth Index. décimale : PER Périodiques Résumé : Youth with autism spectrum disorders frequently experience significant symptoms of anxiety. Empirically supported psychosocial interventions exist, yet access is limited, especially for families in rural areas. Telehealth (i.e. videoconferencing) has potential to reduce barriers to access to care; however, little is known about the feasibility or efficacy of directly intervening with youth with autism spectrum disorders through this modality. This study details the pilot testing of a telehealth version of an empirically supported intervention targeting anxiety in youth with autism spectrum disorders. The primary focus of this study is on feasibility, with evaluation of outcomes as a starting point for future randomized trials. In all, 33 families of youth with autism spectrum disorders and significant anxiety symptoms participated in this study (Telehealth Facing Your Fears (FYF) Intervention: n = 17; Wait-list control: n = 16). Youth of all functioning levels were included. Acceptability was strong; however, the usability of the technology was problematic for some families and impeded some sessions significantly. Fidelity of the telehealth version to the critical elements of the original, in vivo version was excellent. More work is needed to improve delivery of exposure practices and parent coaching. Preliminary efficacy analyses are promising, with improvements observed in youth anxiety over time (relative to a comparison group waiting for live intervention) and parent sense of competence (within group). Clearly, stronger designs are necessary to evaluate efficacy sufficiently; however, this study does provide support for further investigation of clinic-to-home videoconferencing as a direct intervention tool for youth with autism spectrum disorders and their parents.
