Poor sleep quality and low behavioral functioning are commonly reported in children with autism spectrum disorder. This study examined the impact of exercise on sleep on melatonin level and behavioral functioning in the population. Children with autism spectrum disorder (n = 55; age = 10.97 ± 1.90) were randomly allocated to a morning jogging…

Restricted and repetitive behaviors (RRB) are observed in young children with intellectual and developmental delays or disabilities (DD) including autism spectrum disorders (ASD). Self-injurious behavior is often considered an extreme form of RRB, but the nature of the relation between SIB and other forms of RRBs is not completely understood.…

The COVID-19 pandemic has changed our lives and affected different nations in different ways. In Algeria, education has been hit hard by the lockdown as schools embarked on a total closure to stop the spread of the virus. For students and their parents, such a closure meant limited access to the support embodied in the school. This qualitative…

The social and motor context in which restricted and repetitive behaviors (RRBs) occur in autism and their relationship to social traits are not well-understood. Participants with and without autism completed tasks that varied in social and motor engagement and RRB frequency was measured. Motor and verbal RRBs were most common, RRBs varied based…

This study explored regression patterns in 100 children with ASD (3-11 years) using several approaches to enhance the validity of retrospective parent report. Both early development and outcome were examined in regression groups defined by 36 months age cut-off and two underlying empirical patterns based on type and onset age. Results over…

Repetitive behaviors are observed in autism spectrum disorder and obsessive-compulsive disorder. Clinically, obsessive-compulsive disorder obsessions are thought to drive repetitive or ritualistic behavior designed to neutralize subjective distress, while restricted and repetitive behaviors are theorized to be reward- or sensory-driven. Both…

Neurofibromatosis Type 1 (NF1) is a common autosomal dominant single-gene disorder, in which the co-occurrence of autism spectrum disorder (ASD) has attracted considerable research interest recently with prevalence estimates of 21-40%. However, detailed characterization of the ASD behavioral phenotype in NF1 is still lacking. This study…

Background: There is a need for a more accurate characterisation of higher level restricted and repetitive behaviour (RRB) in autism spectrum disorder (ASD), including why it might be considered problematic and events associated with its occurrence. Method: We selected one form of higher level RRB--arranging and ordering--that was rated as severe…

The aim of the current pilot study was to evaluate the implementation of a "routines-based early childhood intervention" (RBECI) model by Australian Early Childhood Intervention (ECI) professionals. The RBECI model consisted of four key components: (a) Routines-Based Interviews (RBIs), (b) participation-based goals, (c) home visits, and…

Objective: To use confirmatory factor analysis to test the construct validity of the proposed "DSM-5" symptom model of autism spectrum disorder (ASD), in comparison to alternative models, including that described in "DSM-IV-TR." Method: Participants were 708 verbal children and young persons (mean age, 9.5 years) with mild to severe autistic…

The purpose of this qualitative study was to explore the lived experience of how sensory-related behaviors of children with autism affected family routines. In-depth semi-structured interviews were conducted with four primary caregivers regarding the meaning and impact of their child's sensory-related behaviors on family routines that occurred…
