Rachel Plak; Ralph Rippe; Inge Merkelbach; Sander Begeer – Journal of Autism and Developmental Disorders, 2024
Studies on the impact of the COVID-19 pandemic on autistic children's psychosocial outcomes have shown mixed results. In the current study we aimed to gain a better insight into the effect of the COVID-19 pandemic by comparing psychosocial outcomes collected pre-pandemic with data collected during the pandemic. We used the Strengths and…

Li-Gao, Ruifang; Boomsma, Dorret I.; Dolan, Conor V.; De Geus, Eco J. C.; Denollet, Johan; Kupper, Nina – Developmental Psychology, 2022
Feeling inhibited and socially not at ease is reflected in the trait social inhibition (SI). SI is associated with psychopathology that arises in young adulthood, such as anxiety. We aim for a better insight into the genetic and environmental contributions to SI across the life span, and as such examine their contributions to SI stability and…

Jonkman, Kim M.; Back, Elisa; Begeer, Sander – Autism: The International Journal of Research and Practice, 2023
Autism is a heterogeneous diagnosis with symptoms that present in different ways. There is a large variety of interventions for autistic individuals. However, little is known about who chooses which specific interventions. We aimed to explore intervention prevalence and predict intervention use, based on demographic and autism-specific…

This study examined self-descriptions of high-performing students and other students and compared the descriptions of these two groups. The concept map, with the open-ended question "Who am I?," was completed by 133 high-performing students and 160 other students. The self-descriptions of these students were subdivided into eleven…

Verhagen, Josje; Van Tiphout, Mees; Blom, Elma – Journal of Child Language, 2022
Previous research on the effects of word-level factors on lexical acquisition has shown that frequency and concreteness are most important. Here, we investigate CDI data from 1,030 Dutch children, collected with the short form of the Dutch CDI, to address (i) how word-level factors predict lexical acquisition, once child-level factors are…

Buijsman, Riley; Begeer, Sander; Scheeren, Anke M. – Autism: The International Journal of Research and Practice, 2023
The language used to refer to autism has been a topic of ongoing debate. Research in English-speaking countries indicated an overall preference for identity-first language ('autistic person') among autistic adults rather than person-first language ('person with autism'). We examined terminology preference in Dutch autistic adults (n = 1026; 16-84…

Mesman, Judi; de Bruijn, Ymke; van Veen, Daudi; Pektas, Fadime; Emmen, Rosanneke A. G. – Child Development, 2022
A prerequisite to anti-racist socialization in families is acknowledging ethnic-racial (power) differences, also known as color-consciousness. In a sample of 138 White Dutch families from the urban Western region of the Netherlands with children aged 6-10 years (53% girls), observations and questionnaires on maternal color-consciousness and…

Liu, Fangyuan; Scheeren, Anke M.; Grove, Rachel; Hoekstra, Rosa A.; Wang, Ke; Guo, Dehua; Wang, Chongying; Begeer, Sander – Journal of Autism and Developmental Disorders, 2022
Autism spectrum disorders are diagnosed globally, but recognition, interpretation and reporting may vary across cultures. To compare autism across cultures it is important to investigate whether the tools used are conceptually equivalent across cultures. This study evaluated the factor structure of the parent-reported Autism Spectrum Quotient…

Introduction: Individuals with ADHD continue to face stigma, which can negatively impact their access to, adherence to, and quality of mental health services, as well as their overall wellbeing. Perspectives of various stakeholders regarding priorities for stigma reduction remain underexplored. This study explores young adult, parent, teacher, and…

Dapprich, Anna L.; Tyborowska, Anna; Niermann, Hannah C. M.; Becker, Eni S.; Cillessen, Antonius H. N.; Roelofs, Karin – International Journal of Behavioral Development, 2022
Callous-unemotional (CU) traits predict behavioral problems in adolescence. But little is known about early modulatory factors. Behavioral Inhibition (BI) in particular has been suggested to protect against the development of CU-traits. This temperamental predisposition is characterized by heightened environmental sensitivity. The current…

A retrospective chart study of patients on open-label aripiprazole treatment was conducted in the Netherlands to add to the knowledge of aripiprazole in children and young adults with mild and borderline intellectual disabilities (IDs). Fifty-three youths, mean age 14.7 ± 3.4 years and mean IQ 64.5 ±13.8, were included. Treatment responders were…

Özerk, Kamil – International Electronic Journal of Elementary Education, 2018
The prevalence of autism/autism spectrum disorder (ASD) has been increasing across the world. Previous studies in Norway reported, that the prevalence rate for 0-10-year-old children is 1 in 166, and in the case of 11-year-old children it is 1 in 125. Moreover, another nationwide study discovered that 1 in 192 males and 1 in 695 females between…

Siméon T. A. Lahaije; Jorien Luijkx; Aly Waninge; Annette A. J. van der Putten – International Journal of Developmental Disabilities, 2024
Families with a child with profound intellectual and multiple disabilities (PIMD) have to manage the child's pervasive support needs. To ensure that families are able to manage these needs, they should be properly supported. However, knowledge about the specific support needs of these families is sparse and fragmented, nor is it known if and which…

Vogelaar, Bart; Resing, Wilma C. M.; Stad, Femke E. – Journal of Cognitive Education and Psychology, 2020
This study investigated potential differences in the processes of solving analogies between gifted and average-ability children (aged 9-10 years old) in a dynamic testing setting. Utilizing a pre-test-training-post-test control group design, participants were split in four subgroups: gifted dynamic testing (n = 24), gifted control (n = 26),…

Kentrou, Vasiliki; de Veld, Danielle MJ; Mataw, Kawita JK; Begeer, Sander – Autism: The International Journal of Research and Practice, 2019
Phenotypic elements of autism spectrum disorder can be masked by attention-deficit/hyperactivity disorder symptoms, potentially leading to a misdiagnosis or delaying an autism spectrum disorder diagnosis. This study explored differences in the age of autism spectrum disorder diagnosis between participants with previously diagnosed…
