Individuals with autism spectrum disorder commonly exhibit vocal stereotypy, and this behavior may be targeted for treatment when it competes with daily tasks, disrupts the environment, or leads to reduced independence. Previous research has shown that access to music reduces vocal stereotypy. However, treatment evaluations typically occur during…

Both naturalistic developmental behavioral interventions (NDBIs) and augmentative and alternative communication (AAC) have been shown to support the language development of children with a diagnosis of autism spectrum disorder and minimal speech. However, little research has addressed the impact of incorporating AAC systems within NDBIs. This…

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…

The social validity of autism behavioral intervention has been questioned. Naturalistic Developmental Behavioral Interventions (NDBIs) attempt to address some concerns, but it is unclear whether autistic people consider NDBIs socially valid. Social validity of an NDBI, Pivotal Response Treatment (PRT), was investigated through autistic adults…

We replicated and extended Kanaman et al. (2022) by comparing outcomes of solitary (leisure items only), social (leisure items with social interaction), and combined (leisure items alone and leisure items with social interaction) stimulus preference assessments to determine the extent to which the inclusion of social interaction influenced the…

As educators who provide support to individuals with ASD, our primary goal should be to teach the skills necessary to live as independently as possible. As critically important as these skills are, teaching independent living skills can sometimes be challenging when motivation is low. These issues become even more complicated as individuals get…

Children with autism spectrum disorder often exhibit difficulties in social communication and interaction. Those who do not acquire functional communication to effectively express wants and needs often are at a higher risk of displaying challenging behaviors. Mand training is recognized as an evidence-based intervention for teaching communication…

Behavioral skills training (BST) delivered synchronously via telecommunication (telehealth) has been shown to be effective for training mediators supporting children with autism. A limitation in the literature is that many published training protocols are evaluated under analogue or highly controlled conditions; therefore, further evaluation is…

Anxiety disorders occurs at a high rate amongst autistic children. Cognitive behaviour therapy (CBT) is a reasonably well-established multi-component intervention used to reduce anxiety in this population. Whilst there are known effective intervention components in CBT for treating anxiety among autistic children, there are few guidelines for how…

This trial examined stepped-care cognitive-behavioral treatment (CBT) among 96 autistic youth with co-occurring anxiety. Step 1 included an open trial of parent-led, therapist-guided bibliotherapy. Step 2 was family-based CBT for those who did not respond to Step 1 or maintenance for those who did. Eighteen participants (28%) who completed Step 1…

Purpose: Cognitive behaviour therapy based on the Clark and Wells (1995) model is a first-line treatment for neurotypical people seeking support for social anxiety. While autistic people frequently report high social anxiety, it is unclear how appropriate the model is for this population. Methods: Over 300 autistic and non-autistic adults…

Differential reinforcement of alternative behavior (DRA) is a common strategy for escape-maintained behaviors targeted for reduction (i.e., targeted behavior) exhibited by youth with intellectual and developmental disabilities. DRA often involves various methods of prompting to ensure the instruction or task remains in place until contingencies…

Autistic children experience high rates of mental health challenges, and links have been found between child mental health and the parent-child relationship. As parents of autistic children are often actively involved in their child's treatment, it is important to consider aspects of the parent-child relationship within this context. The present…

Behavioral skills training (BST) is a performance- and competency-based training package composed of instructions, modeling, rehearsal, and feedback. Previous reviews have demonstrated that BST is an effective training package to teach interventionists to implement behavior analytic interventions (Kirkpatrick et al. in "Journal of Behavioral…

Limited research has examined the active ingredients and mechanisms of change of naturalistic developmental behavioral interventions (NDBIs). The present study used an exploratory sequential mixed-methods design to develop a comprehensive Theory of Change of Project ImPACT, an empirically supported NDBI. We used qualitative data from interviews…
