To test this hypothesis, fifty-three children with ASD (mean age = 11.9) underwent structural MRI and were divided into subgroups to compare those with at least one anxiety disorder diagnosis (n = 29) to those without (n = 24) and to a typically developing control group (TDC; n = 37). Groups were matched on age and intellectual level. The ASD and anxiety group showed decreased right amygdala volume (controlled for total brain volume) relative to ASD without anxiety (p = .04) and TDCs (p = .068). Results suggest that youth with ASD and co-occurring anxiety have a distinct neurodevelopmental trajectory.

Behavioral inhibition and activation as a modifier process in autism spectrum disorder: Examination of self-reported BIS/BAS and alpha EEG asymmetry / Hillary K. SCHILTZ in Autism Research, 11-12 (December 2018)  

Public ISBD [article]  inAutism Research > 11-12 (December 2018) . - p.1653-1666 Titre : Behavioral inhibition and activation as a modifier process in autism spectrum disorder: Examination of self-reported BIS/BAS and alpha EEG asymmetry Type de document : texte imprimé Auteurs : Hillary K. SCHILTZ, Auteur ; Alana J. MCVEY, Auteur ; Alexander BARRINGTON, Auteur ; Angela D. HAENDEL, Auteur ; Bridget K. DOLAN, Auteur ; Kirsten S. WILLAR, Auteur ; Sheryl PLEISS, Auteur ; Jeffrey S. KARST, Auteur ; Elisabeth VOGT, Auteur ; Christina C. MURPHY, Auteur ; Kelsey GONRING, Auteur ; Amy V. VAN HECKE, Auteur Article en page(s) : p.1653-1666 Langues : Anglais (eng) Mots-clés : alpha asymmetry  autism  behavioral inhibition and activation  comorbidities Index. décimale : PER Périodiques Résumé : The Modifier Model of autism spectrum disorder (ASD) suggests that phenotypic variability within ASD is rooted in modifier processes, such as the behavioral inhibition system (BIS) and behavioral activation system (BAS). Among a sample of 53 adolescents with ASD, this study examined associations between (a) self-reported BIS/BAS and frontal and parietal alpha electroencephalogram asymmetry and whether these indices related to (b) ASD severity (via the Autism Quotient), and/or (c) co-occurring anxiety and attention-deficit hyperactivity disorder (via Youth Self Report and Child Behavior Checklist). Findings showed that alpha asymmetry was associated with self-reported BAS scores, such that greater BAS was related to greater right-frontal hemisphere activation and relatively greater left-parietal hemisphere activation. Additionally, associations emerged between ASD severity and self-reported BAS and alpha asymmetry, and between anxiety symptoms and self-reported BIS and alpha asymmetry. Furthermore, mediation analyses revealed that BAS mediated the association between asymmetry and autism severity. Therefore, alpha asymmetry and BIS/BAS activity may provide insight into how ASD presents in adolescence as well as who might be at greater risk for developing co-occurring psychopathologies. This study highlights the importance of considering motivational systems to elucidate individual differences among youth with ASD and working toward the longer term goal of better understanding differential responses to treatment. Autism Research 2018, 11: 1653-1666. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Differences in the likelihood to avoid (behavioral inhibition system; BIS) or approach (behavioral activation system; BAS) situations are thought to relate to patterns of brain activity (via electroencephalogram asymmetry asymmetry). This study revealed that these tendencies may influence the presentation of autism spectrum disorder (ASD) and symptoms of anxiety in adolescents with ASD.

Brief Report: Does Gender Matter in Intervention for ASD? Examining the Impact of the PEERS® Social Skills Intervention on Social Behavior Among Females with ASD / Alana J. MCVEY in Journal of Autism and Developmental Disorders, 47-7 (July 2017)

Females with ASD may have more difficulty developing meaningful friendships than males, as the social climate can be more complex (Archer, Coyne, Personality and Social Psychology Review 9(3):212–230, 2005). This study examined whether treatment response among females differed from males. One hundred and seventy-seven adolescents and young adults with ASD (N = 177) participated in this study. When analyzed by group, no significant differences by gender emerged: PEERS® knowledge (TASSK/TYASSK, p = .494), direct interactions (QSQ, p = .762), or social responsiveness (SRS, p = .689; SSIS-RS, p = .482). Thus, females and males with ASD respond similarly to the PEERS® intervention.

Little work has explored broad features of these presentations in a non-clinical sample. College students (n=174) ages 18-22 years completed questionnaires assessing the broader autism phenotype (BAP), autistic features, nonconformity to gender norms, and internalizing symptoms. Those with more BAP features or autistic communication reported more nonconformity to gender norms. Higher levels of internalizing symptoms were related to more gender nonconformity, BAP, and autistic features. Gender nonconformity marginally moderated the effect of BAP on depression but not anxiety. The BAP, autistic features, and gender nonconformity are important in understanding mental well-being.

Changes in Depressive Symptoms Among Adolescents with ASD Completing the PEERS((R)) Social Skills Intervention / Hillary K. SCHILTZ in Journal of Autism and Developmental Disorders, 48-3 (March 2018)

The present data, from a randomized controlled trial, examined the effect of PEERS((R)) on self-reported depressive symptoms via the Children's Depression Inventory (CDI) among 49 adolescents with ASD. Findings revealed that many CDI subscale scores declined (p's < 0.05) and were related to direct social contact on the Quality of Socialization Questionnaire at posttest (p's < 0.05). Exploratory analyses uncovered that suicidality was less evident following PEERS((R)). Findings support the notion that social functioning and depression may be intimately intertwined in ASD; therefore, bolstering social skills in ASD may positively influence other domains of functioning, including mental health.
