Somatic Symptoms in a Population-Based Sample from Childhood to Adolescence: Stability and Concurrent and Longitudinal Predictors.

The present study investigated group and individual stability and predictors of somatic symptoms from childhood to adolescence in a population-based sample. 259 youth were evaluated at 6-12 years (M 8.1) and 8 years later (M 15.

Oppositional Defiant Disorder in Autism and ADHD.

Our study compared oppositional defiant disorder (ODD) in children with autism to ADHD-Combined presentation and ADHD-Inattentive presentation. Mothers of 2,400 children 3-17 years old with autism and/or ADHD completed the Pediatric Behavior Scale. ADHD-Combined was most strongly associated with ODD, with an ODD prevalence of 53% in children with ADHD-Combined only.

Feasibility and acceptability of a telehealth intervention for improving peer relationships for adolescents with neurofibromatosis type 1: a single-arm pilot study.

Objective: Elevated rates of social difficulties are evident for children and adolescents with neurofibromatosis type 1 (NF1) but the effects of social skills interventions have not been investigated for this population. The Program for the Education and Enrichment of Relational Skills (PEERS®), a widely established social skills intervention in autism spectrum disorders with expansion to other conditions, was recently modified to be offered virtually. This study examined the feasibility and acceptability of this telehealth intervention.

Prevalence and Correlates of Poor Safety Awareness and Accidental Injury in ASD, ADHD, ASD + ADHD, and Neurotypical Youth Samples.

The purpose of the present study is to compare risk and predictors of poor safety awareness and accidental injuries in ASD, ADHD, and neurotypical samples. Neurodivergent groups (ADHD-I n = 309; ADHD-C n = 747; ASD-only n = 328; ASD + ADHD n = 1,108) were 2-17 years old. The neurotypical group (n = 186) was 6-12 years of age.

Pilot study of the effectiveness of a telehealth group for improving peer relationships for adolescents with neurofibromatosis type 1.

Background: Interventions for social difficulties have not been investigated in the neurofibromatosis type 1 (NF1) population despite observations of elevated rates of social difficulties. In this pilot study, the effectiveness of a 14-week telehealth PEERS® intervention with nineteen adolescents with NF1 (M=13.79 years, SD = 1.

An evaluation of computerized attention and executive function measures for use with school age children with neurofibromatosis type 1.

The present study investigated the performance of children with neurofibromatosis type 1 on computerized assessments of attention and executive function. Relations to ADHD symptomatology were also examined. Participants included 37 children (20 male) with NF1 (9-13 years; M = 11.

Psychometric Properties of Attention Measures in Young Children with Neurofibromatosis Type 1: Preliminary Findings.

Children with neurofibromatosis type 1 (NF1) often demonstrate difficulties with attention and executive functioning that can be evident starting at a young age. There has been little research about which measures of attention are most suitable for use with young children with NF1. This pilot study explored several computerized measures of attention, a digits forward task, and parent report measures of attention to compare their reliability, validity, and the degree to which they capture attention difficulty in this population.

Brief Report: A Pilot Study Examining the Effects of PEERS® for Adolescents Telehealth for Autistic Adolescents.

The COVID-19 pandemic sparked a worldwide transition to providing online services overnight, highlighting the urgent need for empirically supported telehealth interventions. The current study examined the effects of PEERS® for Adolescents Telehealth, an adaptation from the original social skills intervention developed for in-person provision, among 22 autistic adolescents and their caregivers. To evaluate the intervention, caregivers completed questionnaires assessing core autistic features and frequency of get-togethers.

Patterns of performance of children with neurofibromatosis type 1 on the K-CPT and K-CPT 2.

Children with neurofibromatosis type 1 (NF1) often have attention difficulties with emerging evidence that these difficulties can be seen even in early childhood. This study aimed to explore the relative utility of two versions of a commonly used computerized attention measure for young children with NF1 and to explore relations with parent-reported attention in young children with NF1. Two independent samples of young children with NF1 participated.

Longitudinal Investigation of Early Motor Development in Neurofibromatosis Type 1.

Objective: Research indicates that children with neurofibromatosis type 1 (NF1) have weaknesses in fine and gross motor development in early childhood; however, little is known about the stability and developmental trajectory of motor functioning. We investigated (1) whether motor difficulties are evident and stable in the preschool period in children with NF1 and (2) whether there are particular patterns of motor development in this population.

Methods: Participants with NF1 and a control group of unaffected siblings were enrolled at ages 3-8 years and were assessed yearly.
