Involving typically developing (TD) children in delivering interventions can be an effective strategy conducive to long-lasting and generalized behavior changes for their siblings with autism spectrum disorder (ASD). In this study, we recruited two sibling dyads and investigated the extent to which TD children could deliver the model-lead-test…

Purpose: Comparative data of autism-sensitive standardized measures of emotion regulation and lability, describing percentage change over time for populations of young autistic children, are currently publicly unavailable. We propose publication of such data as a support for future therapeutic intervention studies. Methods: We generate and present…

Early identification of autism spectrum disorder through cost-effective screening is crucial in low- and middle-income countries. The Child Behavior Checklist 1.5-5, using the Autism Spectrum Problems and Withdrawn Syndrome subscales, has potential as a level 1 autism spectrum disorder screening tool, though its construct validity in low- and…

Prior research has shown conflicting findings on decision-making differences between autistic and non-autistic individuals. To address this issue, we applied the Ultimatum and Dictator Games to examine explicit measures (probability of endorsing monetary offers) and implicit measures (response times) associated with decision-making behaviors. By…

Autistic people with intellectual disabilities appear to be at increased risk of schizophrenia. While current recommendations emphasize adapting interventions used for people with schizophrenia in general, few studies to date have investigated treatment of co-occurring schizophrenia in this specific population. To explore what interventions are…

Problems with executive function (EF) are considered a hallmark of Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). However, little is known about the developmental pathway of everyday EF in these two groups, and whether the two groups follow a similar or different developmental course. In this longitudinal…

The first aim of this study was to construct/validate a subscale--with cut-offs considering gender/age differences--for the school-age Child Behavior CheckList (CBCL) to screen for Autism Spectrum Disorder (ASD) applying both data-driven (N = 1666) and clinician-expert (N = 15) approaches. Further, we compared these to previously established CBCL…

Background: Screening is the first important step in the diagnostic process. There is strong evidence that early diagnosis and management of autism spectrum disorder (ASD) can lead to a better prognosis. The purpose of this study was to develop an Arabic version of the Chinese Checklist for Autism in Toddlers-23 (CHAT-23) to distinguish children…

In recent years, there has been a proliferation of instruments for assessing mental health (MH) among autistic people. This study aimed to review the psychometric properties of broadband instruments used to assess MH problems among autistic people. In accordance with the PRISMA guidelines (PROSPERO: CRD42022316571) we searched the APA PsycINFO via…

"Emotion Regulation" is a key factor in the psychological well-being of children on the autism spectrum. Therapeutic "co-regulation" is posited here as fundamental to addressing Emotion Regulation needs. A therapeutic combination of "Child-Centred Play Therapy" and "Rhythmic Relating" is assessed in its…

Purpose: Comparative data of autism-sensitive standardized measures of emotion regulation and lability, describing percentage change over time for populations of young autistic children, are currently publicly unavailable. We propose publication of such data as a support for future therapeutic intervention studies. Methods: We generate and present…

3q29 deletion syndrome (3q29del) is associated with a significantly increased risk for neurodevelopmental and neuropsychiatric disorders. However, the full spectrum of behavioral phenotypes associated with 3q29del is still evolving. Individuals with 3q29del (n = 96, 60.42% male) or their guardian completed the Achenbach Child or Adult Behavior…

Research findings on the prevalence and characteristics of behavioral problems of children with hearing loss (HL) are not consistent. The aim of this study was to compare the behavioral problems of children with HL, with typical development (TD) and with autism spectrum disorder (ASD); and to determine the factors affecting behavioral problems in…

Males are more likely to be diagnosed with autism than females, and at earlier ages, yet few studies examine sex differences in screening. This study explored sex differences in psychometric properties, recommended cutoff scores, and overall scores of the Modified Checklist for Autism in Toddlers, Revised, with Follow-Up. Participants were 28,088…

Fragile X syndrome (FXS) is characterized by variable neurobehavioral abnormalities, which leads to difficulties in developing and evaluating treatments and in determining accurate prognosis. We employed a pediatric cross-sectional sample (1,072 males, 338 females) from FORWARD, a clinic-based natural history study, to identify behavioral subtypes…
