May, Tamara; Pang, Ken C.; O'Connell, Michele A.; Williams, Katrina – Journal of Autism and Developmental Disorders, 2017
Secondary data analyses from the Longitudinal Study of Australian Children Kindergarten cohort were performed to understand any alterations in pubertal timing in Autism Spectrum Disorder (ASD) in a population sample. Timing of parent-reported pubertal events (ages 8-9, 10-11, 12-13 years), and self-report (14-15 years; N = 3454 no ASD, N = 94 with…

Hatch, Burt; Iosif, Ana-Maria; Chuang, Annie; de la Paz, Leiana; Ozonoff, Sally; Miller, Meghan – Journal of Autism and Developmental Disorders, 2021
Diminished response to name, a potential early marker of autism spectrum disorder (ASD), may also indicate risk for other disorders characterized by attention problems, including attention-deficit/hyperactivity disorder (ADHD). Using a familial risk design, we examined whether response to name ability at 6, 12, 18, 24, and 36 months of age…

Here we report the results of the subgroup analyses of an observational cohort of children whose parents completed the Autism Treatment Evaluation Checklist (ATEC) over the period of several years. A linear mixed effects model was used to evaluate longitudinal changes in ATEC scores within different patient subgroups. All groups decreased their…

May, Tamara; Pang, Ken C.; Williams, Katrina – Journal of Autism and Developmental Disorders, 2017
Past research suggests more variation in sexual attraction in Autism Spectrum Disorder (ASD) using clinical samples. This study utilised a population representative group of 14/15 year olds from the Longitudinal Study of Australian Children. Ninety-four adolescents (73 males, 21 females) with ASD and 3454 (1685 males, 1675 females) without…

Crawford, Hayley; Karakatsani, Efthalia; Singla, Gursharan; Oliver, Chris – Journal of Autism and Developmental Disorders, 2019
Self-injurious and aggressive behaviors are common in fragile X syndrome (FXS). However, little is known about the persistence of these behaviors and associated risk markers. We established the prevalence and persistence of self-injurious and aggressive behaviors over eight years in males with FXS, and associations with risk markers. Results…

Lawson, Lauren P.; Joshi, Rucha; Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2018
Relatively few studies have examined gender differences in infants and toddlers, and most focus on clinically referred samples or high-risk infant cohorts. The current study aimed to examine gender differences in early autism manifestations and cognitive development in a community-ascertained sample. In total, 46 males and 21 females with ASD were…

Prospective studies of infant siblings of children diagnosed with autism spectrum disorder (ASD) provide a unique opportunity to characterize ASD as it unfolds. A critical question that remains unanswered is whether and how these children with ASD resemble other children identified from the community, including those with no family history. The…

Woodman, Ashley C.; Smith, Leann E.; Greenberg, Jan S.; Mailick, Marsha R. – Journal of Autism and Developmental Disorders, 2015
Little is known about outcomes for individuals with autism spectrum disorders (ASD) into adulthood. Several characteristics of individuals with ASD predict long-term outcomes, and the family environment may also play a role. The present study uses a prospective, longitudinal design to describe and predict trajectories of autism symptoms and…

Possible gender differences in manifestations of autism spectrum disorder (ASD) were examined using data on production of narratives. The Expression, Reception and Recall of Narrative Instrument (ERRNI; Bishop, Expression, Reception and Recall of Narrative Instrument, Harcourt assessment, London, 2004) was administered to a sample of matched…

Sparaci, Laura; Northrup, Jessie B.; Capirci, Olga; Iverson, Jana M. – Journal of Autism and Developmental Disorders, 2018
Forty-one high-risk infants (HR) with an older sibling with autism spectrum disorder (ASD) were observed longitudinally at 10, 12, 18 and 24 months of age during a tool use task in a play-like scenario. Changes in grasp types and functional actions produced with a spoon were assessed during elicited tool use. Outcome and vocabulary measures were…

Wise, Elizabeth A.; Smith, Marcia D.; Rabins, Peter V. – Journal of Autism and Developmental Disorders, 2017
Little is known about Autism Spectrum Disorder (ASD) in persons over age 50. In a retrospective, naturalistic review of 74 individuals aged 30 and older meeting DSM-5 criteria for ASD, the point prevalence of behavioral and neuropsychiatric symptoms (BNPS) declined significantly for 12 of 13 BNPS over a mean of 25 years while many other features…

Tonnsen, Bridgette; Scherr, Jessica; Reisinger, Debra; Roberts, Jane – Journal of Autism and Developmental Disorders, 2017
Studying anxiety in neurogenetic syndromes may inform the intersection of biological and developmental risks, facilitating effective and targeted interventions. We longitudinally examined stranger fear in infants and toddlers with fragile X syndrome (FXS; n = 46) and typical controls (n = 33), as well as associations between observed stranger fear…

Preschool children with autism spectrum disorder (ASD) experience slower development of daily living skills (DLS) that are essential for independent functioning compared to typically developing children. Few studies have examined the trajectories of DLS in preschoolers with ASD and the existing literature has reported conflicting results. This…
