This study examined the sustained and moderating effects of a behavioural sleep intervention for autistic children in a randomised controlled trial. Autistic children (5-13 years) with sleep problems were randomised to the Sleeping Sound intervention or Treatment as Usual (TAU). At 12-month follow-up (n = 150), caregivers of children in the…

Purpose: Modifying gut bacteria in children with autism may influence behaviour, with potential to improve family functioning. We conducted a randomised controlled trial to assess the effect of prebiotics on behaviour, gastrointestinal symptoms and downstream effects on parental quality of life. Method: Children with autism (4-10yrs) were…

Clinician and caregiver reports of autism features are both integral to receiving an autism diagnosis and appropriate intervention, yet informant discrepancies are present in clinical practice and may differ by demographic characteristics of the child and family. The present study examined how clinician-caregiver discrepancies in ratings of a…

Among the developmental milestones related to language and communication in early childhood, one that has been the subject of considerable research is response to name (RTN). Delayed or absent RTN in early childhood is a diagnostic marker for autism spectrum disorder and a target behavior in many early intervention curricula. This article…

Network modeling of the social, communication and restrictive/repetitive behaviors (RRBs) included in the definition of Autism Spectrum Disorder was performed. The Autism Diagnostic Interview-Revised (ADI-R) assessed behaviors in 139 pre-school cases at two cross-sections that averaged 34.8 months apart. Cross-sectional networks were based on the…

A positive caregiver-teacher relationship has the potential to promote student progress. Yet, little is understood about factors contributing to effective caregiver-teacher alliance and team building on behalf of students with autism. Data from randomized controlled trials of a home-school collaborative planning and teacher coaching intervention…

While externalizing behaviors are common among children with autism spectrum disorder (ASD), there is a shortage of specialist community-based clinicians to provide treatment. Parent-Child Interaction Therapy (PCIT), an intervention designed to reduce child disruptive behaviors, may be effective for families of children with ASD but has rarely…

Purpose: This study aimed to explore the effect of family-professional partnerships in adapted physical education on the fundamental motor skills, physical activity levels, and adaptive behaviors of children with autism spectrum disorder (ASD) and on parental satisfaction. Methods: A randomized controlled trial design was used, with pre-and…

Despite the popularity of social skills groups, there remains a need for empirical investigation of treatment effects, especially when targeting pivotal aspects of social functioning such as initiations to peers. The goal of the present study was to conduct a randomized controlled trial of a 12-week social intervention (SUCCESS), which combined an…

We examined the effectiveness of coaching on caregiver implementation of responding to joint attention (RJA) intervention for toddlers with autism. We used a nonconcurrent multiple-baseline across participants single-case research design to examine the relation between coaching practices and caregivers' RJA intervention implementation behaviors.…

Supervising behavior technicians in the implementation of services derived from the science of applied behavior analysis with children diagnosed with autism spectrum disorder (ASD) is a common practice for behavior analysts. However, there is limited training available on supervision strategies for those applying this model of services. Lack of…

Many children with autism spectrum disorder experience feeding difficulties that can lead to increased health risks (e.g., severe nutrition deficiencies, obesity-related illnesses) if left untreated. Intensive feeding programs that use behavior-analytic interventions have reported positive outcomes for treating challenging behavior associated with…

This dissertation was designed to determine which behavior analytic intervention was more effective in the treatment and reduction of mouthing non-nutritive substances in children diagnosed with autism. This study included four participants in an A-B-A reversal design with a component analysis across four intervention phases. The study…

The current study explored similarities and differences in parenting stress (PSI) and behaviours in parent reports of autism spectrum disorder (ASD) and attachment disorder (AD). 155 parents whose children had developmental delays and disorders completed the social communication questionnaire, Randolph attachment questionnaire, strengths and…

The current study investigated the effects of an integrative exercise intervention on the behaviours in children with autism spectrum disorder (ASD), and if they were influenced by ASD symptom severity. Sixty-six children (7.56 ± 2.03 yrs.) with ASD were enrolled and categorised as having mild (n = 22), moderate (n = 18) or severe (n = 26)…
