Purpose: An official autism diagnosis is required to access timely intervention and is associated with better long-term wellbeing and mental health. Certain demographic characteristics, such as being female or a racially or ethnically minoritized youth, have been associated with significant diagnostic lag. However, it remains unclear how assigned…

Objective: The study aimed to investigate whether the fine motor skills measured by the Functional Dexterity Test (FDT) in ADHD children differ from healthy controls. The second aim was to assess the applicability of the FDT assessment method among ADHD children. Method: The FDT results as an objective assessment of hand skills were compared…

This quantitative correlational study investigates caregivers' attitudes toward sexual behavior and sex education for children with Down syndrome, drawing upon the theories of reasoned action and planned behavior. Data was collected from a convenience sample of 112 caregivers. The analysis revealed significant positive associations between…

Purpose: People who stutter often experience significant adverse impact related to stuttering. However, it is unclear how adverse impact develops in children who stutter (CWS) and whether there are protective factors that may mitigate its development. This study examined the relationship between resilience, a potentially protective factor, and…

Purpose: To study the relationship between actual motor competence (AMC) and perceived motor competence (PMC) in a large sample of 6- to 12-year-old children. Method: The AMC and PMC were measured (N = 1,669, 55% boys) with the Athletic Skills Track and the Physical Self-Confidence Scale, respectively. A variable-centered approach was applied to…

Data from 83,423 parent reports of temperament (surgency, negative affectivity, and regulatory capacity) in infants, toddlers, and children from 341 samples gathered in 59 countries were used to investigate the relations among culture, gender, and temperament. Between-nation differences in temperament were larger than those obtained in similar…

Past research suggests that children, particularly those with autism spectrum disorder, with general behavioral inflexibility to objects, persons, and environments may be at risk for feeding problems. However, questions remain about whether feeding problems are better predicted by behavioral inflexibility or sensory sensitivity, and whether…

Youth with disabilities are overrepresented in the bullying dynamic and experience poor mental health and school engagement outcomes associated with this involvement. However, limited existing research has looked at differences in bullying involvement based on disability category, and how youth with disabilities make decisions about bullying…

Objective: To provide additional information about clinical features associated with adult ADHD in patients diagnosed in childhood compared to those first diagnosed in adulthood. Method: We stratified a sample of adults with ADHD into patients diagnosed in childhood versus adulthood and compared demographic and clinical characteristics. Results:…

Virtual reality (VR) technology has shown great potential on intervention of social skills for children with autism spectrum disorder (ASD). This review aimed to review the application of VR in current social skills intervention targeting autistic children and evaluate its effect. After searching and screening three databases, we found 20 papers…

Purpose: We extended our earlier study on normative growth curves for intelligibility development in typical children from 30 to 119 months of age. We also determined quantile-specific age of steepest growth and growth rates. A key goal was to establish age-specific benchmarks for single-word and multiword intelligibility. Method: This…

Personal networks undergo changes in structure and composition throughout the life span, adapting to developmental transitions and changing circumstances in a dynamic way. This study examines stability and change in social convoys from childhood to adulthood and variation in trajectories of convoy characteristics by gender and race. Multilevel…

The purpose of this study was to examine the factorial invariance of the ASIS (Anadolu Sak Intelligence Scale) across gender. Raw scores from the ASIS standardization study (N = 4641) were used in the analyses. Factorial invariance was analyzed by gender across three age groups: 4-7 (N = 2528), 8-9 (N = 848), and 10-12 (N = 1265) using the…

Autism is a lifelong condition characterized by repetitive and restrictive behaviors and differences in social communication. The reported prevalence of autism has risen exponentially in the past years. Early identification and subsequent early intervention are key to promoting better outcomes for autistic individuals. However, there is a dearth…

This meta-analysis examined communication outcomes in single-case design studies of augmentative and alternative communication (AAC) interventions and their relationship to participant characteristics. Variables addressed included chronological age, pre-intervention communication mode, productive repertoire, and pre-intervention imitation skills.…
