The second to fourth digit (2D:4D) ratio is of interest in autism spectrum disorder (ASD). Studies on the relationship of this ratio with other neurodevelopmental disorders (NDDs) are lacking. Investigating the association between the ratio and NDDs in twins can provide insight into genetic and/or environmental factors driving the ratio. Hand…

The relationship between autism, criminality and psychopathy has gained increased attention in recent years, although research has focused on autism spectrum disorders, and not autistic traits. We measured autistic traits (with the Autism Spectrum Quotient) in a sample of 101 inmates from a high-security prison and compared them to a control…

The co-occurrence of learning disabilities (LD), such as speech and language impairment (SLI) and attention deficit disorder/attention deficit-hyperactivity disorder (ADD/ADHD), also classified as other health impairment (OHI), is significant. Many of these students are being placed in the general education setting and need to obtain the learning…

In the context of best practices consultation with high needs teachers, we examined (1) relations between teachers' appropriate response to student rule violations and rates of rule violations, and (2) rates of student misbehavior among teachers who do and do not achieve various benchmarks of integrity and/or growth in skills. Participants were 48…

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…

Many students on the autism spectrum attend mainstream schools and face challenges coping with the demands of this complex environment. Education in rural and remote locations poses additional challenges due to limited access to additional resourcing, specialised support, and services. This case study describes a problem-solving, collaborative…

There is a discrepancy in attention deficit/hyperactivity disorder (ADHD) services between students who receive a 504 plan and those found eligible under the Individuals with Disabilities Education Improvement Act for special education services under the other health impairment category (Spiel et al., 2014). As school-based administrators are…

Approximately one in 10 children in the United States is diagnosed with attention-deficit/hyperactivity disorder (ADHD), a disability that can negatively affect academic achievement, yet relatively few children with ADHD are in special education. To better understand factors that determine which students with ADHD are in special education, we…

Growing evidence demonstrates associations between child race, teacher-child race match, and teacher ratings of externalizing behaviour problems in the early years of school. The present study deepens understanding of the relations between child, teacher, and classroom racial factors and teacher-reported externalizing behaviours by examining…

Although school violence is on the decline, it remains a significant concern for the general public, policymakers, and researchers. This report commissioned by the National Institute of Justice (NIJ) takes a comprehensive look at the state of the research on school violence and includes additional discussions about research on serious violence and…

Attention deficit/hyperactivity disorder (ADHD) is characterized by persistently high levels of inattention, hyperactivity, and/or impulsivity that interfere with functioning. Inattention is significantly related to lower reading outcomes, whereas hyperactivity/impulsivity alone is not. Strategies to Read Information Texts and Vocabulary…

Adults with autism spectrum disorder often experience co-occurring mental health problems such as attention-deficit/hyperactivity-disorder, as well as impairments in executive function. Sluggish cognitive tempo, a cluster of behaviors including slow processing, daydreaming, and mental fogginess, has been shown to be associated with…

We examined racial and ethnic differences in the prevalence of behavioral problems measured by the Child Behavioral Checklist (CBCL), sleep disturbances measured by the Child Sleep Habits Questionnaire (CSHQ), and medication use among children with Autism Spectrum Disorders (ASD). We analyzed data from the Autism Treatment Network (ATN) dataset…

With rising pressure and an increase in expected academic performance in schools across the United States, students are experiencing higher levels of stress than ever before. To address this issue, the present study examined the impact of mindfulness-based yoga interventions on fifth-grade students' perceived anxiety and stress levels through a…

Background: Effectiveness studies indicate various classroom management strategies (CMSs) that are helpful for students with attention-deficit/hyperactivity disorder (ADHD), but little is known about teachers' experiences with these CMSs in school practice. Objective: This study examined primary and secondary school teachers' reported frequency of…
