Trial Summary

What is the purpose of this trial?

The purpose of this study is to examine the effectiveness of pivotal response training (PRT) in an intensive center-based environment to treat social communication deficits in children with autism spectrum disorder (ASD).

Will I have to stop taking my current medications?

The trial requires that participants have stable treatment, including medications, for at least 1 month before starting and no changes are expected during the study. So, you should not stop taking your current medications.

What data supports the effectiveness of the treatment Pivotal Response Treatment (PRT-C) for autism?

Research shows that Pivotal Response Treatment (PRT) can effectively improve communication and social skills in children with autism. Studies have found that children receiving PRT showed greater improvements in social-communicative skills and overall functioning compared to those receiving usual treatments. ^{1 2 3 4 5}

How is Pivotal Response Treatment (PRT) different from other treatments for autism?

Pivotal Response Treatment (PRT) is unique because it is a naturalistic behavioral intervention that focuses on improving communication and social skills in children with autism by targeting pivotal areas of a child's development, such as motivation and response to multiple cues. Unlike some other treatments, PRT is designed to be flexible and can be integrated into everyday activities, making it more adaptable to individual needs and settings. ^{1 2 3 6 7}

Treatment Details

Interventions

• Pivotal Response Treatment (PRT-C)

Trial Overview The effectiveness of intensive center-based Pivotal Response Training (PRT-C) is being tested to improve social communication in children with ASD. The study will observe how this specific setting influences the progress made by participants.

Participant Groups

Group I: Intensive Center-Based Pivotal Response Treatment (PRT-C) Experimental Treatment 1 Intervention

Intensive Center-Based Pivotal Response Treatment (PRT-C) will consist of a combination of one weekly 60-minute individual parent training session and 12 weekly hours ( 3 hours per day for 4 days per week) with the child in center-based therapy environment for a total of 13 weekly treatment hours.

Group II: Delayed Treatment Group (DTG) Active Control 1 Intervention

Delayed Treatment Group will consist of treatment as usual. At the end of controlled phase, participants in the DTG will be offered PRT-C in a preschool setting in an open-label fashion with a design similar to the double-blind phase.

Findings from Research

Pivotal response treatment (PRT) has been shown to be an effective intervention for improving communication and social functioning in children with autism spectrum disorder (ASD), based on a systematic evaluation of 17 studies.

The studies demonstrated strong adherence to several research quality standards, such as using standardized protocols and objective evaluators, but showed variability in treatment fidelity and the use of longitudinal designs, indicating areas for improvement in future research.

Pivotal response treatment for children with autism spectrum disorder: a systematic review of research quality. Cadogan, S., McCrimmon, AW.[2018]

A randomized controlled trial involving 53 children with autism showed that parents trained in Pivotal Response Treatment (PRT) significantly improved their children's language skills compared to those in a psychoeducation group, with a notable increase in the frequency of child utterances.

The study demonstrated that 84% of parents in the PRT group effectively learned and implemented the techniques, leading to enhanced adaptive communication skills in their children, highlighting the efficacy of PRT as a parent training model for addressing language deficits in young children with autism.

In a randomized controlled trial involving 44 children with Autism Spectrum Disorder (ASD), Pivotal Response Treatment (PRT) led to significant improvements in social-communicative skills after 12 weeks compared to treatment-as-usual (TAU).

PRT also showed larger gains in global functioning and adaptive socialization skills, indicating its potential effectiveness as a therapeutic intervention for children with ASD.

The online model of Pivotal Response Treatment (PRT) delivered through the MindNest Health platform showed good feasibility, with 58% of participants completing the study curriculum, indicating that parents found the online training manageable and engaging.

Parents who participated in the online training reported significant improvements in their confidence and perceptions of treatment effectiveness, with 82% agreeing that the intervention was acceptable, suggesting that this telehealth approach could be a valuable resource for families of autistic children.

Feasibility and Acceptability of Delivering Pivotal Response Treatment for Autism Spectrum Disorder via Telehealth: Pilot Pre-Post Study. Drapalik, KN., Grodberg, D., Ventola, P.[2023]

In a quasi-experimental trial involving 24 children with autism spectrum disorder (ASD) aged 3-8 years, those receiving Pivotal Response Treatment (PRT) showed improvement in autism symptoms compared to those receiving treatment as usual (TAU), with a small effect size.

The study found no significant changes in general problem behavior or parental stress levels for either group, indicating that while PRT may enhance autism symptom management, it does not necessarily affect other related challenges.

Pivotal Response Training (PRT) has shown statistically significant effects in improving language and communication skills for individuals with autism spectrum disorder (ASD), based on a systematic review of 10 randomized controlled trials (RCTs).

While PRT demonstrates promise for language outcomes, the evidence for its effectiveness in other areas is less consistent, highlighting the need for improved study designs to better understand treatment responses and develop tailored guidelines for clinicians.

The pilot study involving seven teachers and students with autism spectrum disorder (ASD) found that training in classroom pivotal response teaching (CPRT) did not significantly improve teachers' implementation fidelity or students' communication skills and maladaptive behaviors.

Despite the lack of measurable improvements in student outcomes, teachers expressed high satisfaction with the CPRT training, suggesting that while the training may not have led to immediate changes, it could still be valuable for educators.
