Assessing the Dim Light Melatonin Onset in Adults with Autism Spectrum Disorder and No Comorbid Intellectual Disability / Emma K. BAKER in Journal of Autism and Developmental Disorders, 47-7 (July 2017)

Sixteen adults with ASD (ASD-Only), 12 adults with ASD medicated for comorbid diagnoses of anxiety and/or depression (ASD-Med) and 32 controls participated in the study. Although, the timing of the DLMO did not differ between the two groups, advances and delays of the melatonin rhythm were observed in individual profiles. Overall mean melatonin levels were lower in the ASD-Med group compared to the two other groups. Lastly, greater increases in melatonin in the hour prior to sleep were associated with greater sleep efficiency in the ASD groups.

Examining the Behavioural Sleep-Wake Rhythm in Adults with Autism Spectrum Disorder and No Comorbid Intellectual Disability / Emma K. BAKER in Journal of Autism and Developmental Disorders, 47-4 (April 2017)

BAKER, Auteur ; Amanda L. RICHDALE, Auteur Article en page(s) : p.1207-1222 Langues : Anglais (eng) Mots-clés : Autism  Adults  Sleep-wake rhythm  Circadian  DSWPD  ASWPD Index. décimale : PER Périodiques Résumé : This study aimed to examine the behavioural sleep-wake rhythm in 36 adults with autism spectrum disorder (ASD) and to determine the prevalence of circadian sleep-wake rhythm disorders compared to age- and sex-matched controls. Participants completed an online questionnaire battery, a 14-day sleep-wake diary and 14-day actigraphy assessment. The results indicated that a higher proportion of adults with ASD met criteria for a circadian rhythm sleep-wake disorder compared to control adults. In particular, delayed sleep-wake phase disorder was particularly common in adults with ASD. Overall the findings suggest that individuals with ASD have sleep patterns that may be associated with circadian rhythm disturbance; however factors such as employment status and co-morbid anxiety and depression appear to influence their sleep patterns.

Performance of the Autism Observation Scale for Infants with community-ascertained infants showing early signs of autism / Kristelle HUDRY in Autism, 25-2 (February 2021)  

Public ISBD [article]  inAutism > 25-2 (February 2021) . - p.490-501 Titre : Performance of the Autism Observation Scale for Infants with community-ascertained infants showing early signs of autism Type de document : Texte imprimé et/ou numérique Auteurs : Kristelle HUDRY, Auteur ; Lacey CHETCUTI, Auteur ; Maryam BOUTRUS, Auteur ; Sarah PILLAR, Auteur ; Emma K. BAKER, Auteur ; Stefanie DIMOV, Auteur ; Josephine BARBARO, Auteur ; Jonathan GREEN, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; Kandice J. VARCIN, Auteur Article en page(s) : p.490-501 Langues : Anglais (eng) Mots-clés : developmental psychology  diagnosis  early signs  individual variability/heterogeneity  infants  psychometrics Index. décimale : PER Périodiques Résumé : We investigated whether a commonly used research assessment - the Autism Observation Scale for Infants (AOSI) - accurately measures autism behaviours among infants showing early signs of autism identified within the community. The AOSI is often included in studies tracking the development of infants at increased likelihood of autism, such as the infant siblings of diagnosed children. However, the suitability of this measure has not previously been tested with community-referred infants. We administered the AOSI with infants when aged 9 to 14 months and again 6?months later. Our researchers - independent of the AOSI development team and newly trained on this measure - were able to administer the brief interactive assessment and score it accurately. The infants' AOSI scores were linked to their scores on other established and validated clinical assessments, particularly at the second visit when average age was 18?months. Stronger correspondence of AOSI and other scores at this second visit suggests early autism behaviours are better established and more consistent by 18?months of age, even though these infants showed clear enough signs of possible autism to prompt referral to our study around 12?months of age. However, the moderate association of AOSI scores over time suggests that, like infant siblings - who mostly do not develop autism - community-identified infants showing early signs may also have variable developmental pathways in early life.

Severity of Autism is Related to Children's Language Processing / Edith L. BAVIN in Autism Research, 7-6 (December 2014)

BAVIN, Auteur ; Evan KIDD, Auteur ; Luke A. PRENDERGAST, Auteur ; Emma K. BAKER, Auteur ; Cheryl DISSANAYAKE, Auteur ; Margot PRIOR, Auteur Article en page(s) : p.687-694 Langues : Anglais (eng) Mots-clés : lexical processing  severity of ASD  eye tracking  children Index. décimale : PER Périodiques Résumé : Problems in language processing have been associated with autism spectrum disorder (ASD), with some research attributing the problems to overall language skills rather than a diagnosis of ASD. Lexical access was assessed in a looking-while-listening task in three groups of 5- to 7-year-old children; two had high-functioning ASD (HFA), an ASD severe (ASD-S) group (n?=?16) and an ASD moderate (ASD-M) group (n?=?21). The third group were typically developing (TD) (n?=?48). Participants heard sentences of the form “Where's the x?” and their eye movements to targets (e.g., train), phonological competitors (e.g., tree), and distractors were recorded. Proportions of looking time at target were analyzed within 200?ms intervals. Significant group differences were found between the ASD-S and TD groups only, at time intervals 1000–1200 and 1200–1400?ms postonset. The TD group was more likely to be fixated on target. These differences were maintained after adjusting for language, verbal and nonverbal IQ, and attention scores. An analysis using parent report of autistic-like behaviors showed higher scores to be associated with lower proportions of looking time at target, regardless of group. Further analysis showed fixation for the TD group to be significantly faster than for the ASD-S. In addition, incremental processing was found for all groups. The study findings suggest that severity of autistic behaviors will impact significantly on children's language processing in real life situations when exposed to syntactically complex material. They also show the value of using online methods for understanding how young children with ASD process language.
