Linn Andersson Konke; Terje Falck-Ytter; Emily J. H. Jones; Amy Goodwin; Karin Brocki – Journal of Autism and Developmental Disorders, 2024
The purpose of the current study was to use the infant sibling design to explore whether proband traits of autism and ADHD could provide information about their infant sibling's temperament. This could help us to gain information about the extent to which infant temperament traits are differentially associated with autism and ADHD traits. We used…

Martini, Miriam I.; Merkelbach, Inge; Begeer, Sander – Journal of Autism and Developmental Disorders, 2023
Pre- and post-term children show increased autism risk. Little is known about gestational age (GA) prevalence among autistic children, and their respective autism phenotype. We compared prevalence of pre-, full- and post-term birth between a population-derived sample of N = 606 (137 females, 22.61%) autistic children and adolescents (mean age =…

McFayden, Tyler C.; Fok, Megan; Ollendick, Thomas H. – Journal of Autism and Developmental Disorders, 2022
The current study investigated the impact of birth order on vocabulary and social language development in 1338 first-born and 1049 s-born autistic youth (M age = 9.03 years, SD = 3.57; 86.4% male) from the Simons Simplex Collection. Frequentist and Bayesian analyses revealed mixed findings in language development. There were no differences in…

Sibling Configuration as a Moderator of the Effectiveness of a Theory of Mind Training in Children with Autism: A Randomized Controlled Trial
Peer reviewed Peer reviewed

de Veld, Danielle M. J.; Scheeren, Anke M.; Howlin, Patricia; Hoddenbach, Elske; Mulder, Fleur; Wolf, Imke; Begeer, Sander – Journal of Autism and Developmental Disorders, 2021
This RCT investigated whether participants' sibling configuration moderated the effect of a Theory of Mind (ToM) intervention for children with autism. Children with autism aged 8-13 years (n = 141) were randomized over a waitlist control or treatment condition. Both having more siblings, as well as having an older sibling were related to better…

Pinto, Ofir Y.; Raz, Raanan – Journal of Autism and Developmental Disorders, 2021
Using records from the National Insurance Institute of Israel, we recognized all children with autism spectrum disorders (ASD, N = 8072) or hearing loss (HL, N = 2231) born in Israel between 2005 and 2010. Typical developed children were taken from a random 20% sample of children born during the same years (N = 227,492). Analyses were adjusted for…

Perales-Marín, Alfredo; Peraita-Costa, Isabel; Cervera-Boada, Pablo; Tellez de Meneses, Montserrat; Llopis-González, Agustín; Marí-Bauset, Salvador; Morales-Suárez-Varela, María – Journal of Autism and Developmental Disorders, 2021
The objective is to identify obstetric and perinatal factors that could be significant predictors of ASD and may lead to early detection and intervention. A population-based case-control study including 128 children diagnosed with ASD and 311 controls was conducted. Information was collected through self-reported questionnaires. The factors…

Differences in Cognition and Behaviour in Multiplex and Simplex Autism: Does Prior Experience Raising a Child with Autism Matter?
Peer reviewed Peer reviewed
Direct linkDirect link
Berends, Daniel; Dissanayake, Cheryl; Lawson, Lauren P. – Journal of Autism and Developmental Disorders, 2019
Previous research has found multiplex (MPX) children have an advantage in cognition compared to simplex (SPX) children. However, MPX parent's previous experience with older diagnosed siblings has not been considered. We used a large database sample to investigate the MPX advantage and contribution of birth order. Children from the Autism Genetic…

B.; Kostopolous, P.; Das, S.; Gerig, G.; Styner, M.; Gu, H.; Sullivan, P.; Wright, G. – Journal of Autism and Developmental Disorders, 2018
Preschool-aged siblings of children with ASD are at high-risk (HR) for ASD and related challenges, but little is known about their emerging peer competence and friendships. Parents are the main providers of peer-relationship opportunities during preschool. Understanding parental challenges supporting early peer relationships is needed for optimal…

Visser, Janne C.; Rommelse, Nanda; Vink, Lianne; Schrieken, Margo; Oosterling, Iris J.; Gaag, Rutger J.; Buitelaar, Jan K. – Journal of Autism and Developmental Disorders, 2014
This study examined the differential contribution of pre-and perinatal risks in narrowly versus broadly defined autism spectrum disorder (ASD) and across core symptom domains, IQ and co-morbid problems. Children with a DSM-IV diagnosis of autistic disorder (AD) (n = 121) or pervasive developmental disorder not otherwise specified (PDD-NOS)…

Birth Patterns in Mentally Retarded Autistic Patients.
Peer reviewed Peer reviewed
Yeates-Frederikx, M. H. M.; Nijman, H.; Logher, E.; Merckelbach, H. L. G. J. – Journal of Autism and Developmental Disorders, 2000
Birth data for 1,031 Dutch patients with autism were compared to those of the national population. Separate analyses were performed on diagnostic subgroups (i.e., infantile autism vs. other psychoses with origin specific to childhood), gender, and intelligence. No evidence was found that autism is characterized by a deviant birth pattern.…
