- Pivotal Response Treatment Parent Training for Autism: Findings from a 3-Month Follow-Up Evaluation JOURNAL OF AUTISM AND DEVELOPMENTAL DISORDERS 2015; 45 (9): 2889-2898

With rates of autism diagnosis continuing to rise, there is an urgent need for effective and efficient service delivery models. Pivotal Response Treatment (PRT) is considered an established treatment for autism spectrum disorder (ASD); however, there have been few well-controlled studies with adequate sample size. The aim of this study was to conduct a randomized controlled trial to evaluate PRT parent training group (PRTG) for targeting language deficits in young children with ASD.Fifty-three children with autism and significant language delay between 2 and 6 years old were randomized to PRTG (N = 27) or psychoeducation group (PEG; N = 26) for 12 weeks. The PRTG taught parents behavioral techniques to facilitate language development. The PEG taught general information about ASD (clinical trial NCT01881750; http://www.clinicaltrials.gov).Analysis of child utterances during the structured laboratory observation (primary outcome) indicated that, compared with children in the PEG, children in the PRTG demonstrated greater improvement in frequency of utterances (F(2, 43) = 3.53, p = .038, d = 0.42). Results indicated that parents were able to learn PRT in a group format, as the majority of parents in the PRTG (84%) met fidelity of implementation criteria after 12 weeks. Children also demonstrated greater improvement in adaptive communication skills (Vineland-II) following PRTG and baseline Mullen visual reception scores predicted treatment response to PRTG.This is the first randomized controlled trial of group-delivered PRT and one of the largest experimental investigations of the PRT model to date. The findings suggest that specific instruction in PRT results in greater skill acquisition for both parents and children, especially in functional and adaptive communication skills. Further research in PRT is warranted to replicate the observed results and address other core ASD symptoms.

Feasibility and Effectiveness of Very Early Intervention for Infants At-Risk for Autism Spectrum Disorder: A Systematic Review
JOURNAL OF AUTISM AND DEVELOPMENTAL DISORDERS
2015; 45 (3): 778-794
Early detection methods for autism spectrum disorder (ASD) in infancy are rapidly advancing, yet the development of interventions for infants under two years with or at-risk for ASD remains limited. In order to guide research and practice, this paper systematically reviewed studies investigating interventions for infants under 24 months with or at-risk for ASD. Nine studies were identified and evaluated for: (a) participants, (b) intervention approach (c) experimental design, and (d) outcomes. Studies that collected parent measures reported positive findings for parent acceptability, satisfaction, and improvement in parent implementation of treatment. Infant gains in social-communicative and developmental skills were observed following intervention in most of the reviewed studies, while comparisons with treatment-as-usual control groups elucidate the need for further research. These studies highlight the feasibility of very early intervention and provide preliminary evidence that intervention for at-risk infants may be beneficial for infants and parents.

Pivotal Response Treatment for Infants At-Risk for Autism Spectrum Disorders: A Pilot Study
JOURNAL OF AUTISM AND DEVELOPMENTAL DISORDERS
2013; 43 (1): 91-102
Presently there is limited research to suggest efficacious interventions for infants at-risk for autism. Pivotal response treatment (PRT) has empirical support for use with preschool children with autism, but there are no reports in the literature utilizing this approach with infants. In the current study, a developmental adaptation of PRT was piloted via a brief parent training model with three infants at-risk for autism. Utilizing a multiple baseline design, the data suggest that the introduction of PRT resulted in increases in the infants' frequency of functional communication and parents' fidelity of implementation of PRT procedures. Results provide preliminary support for the feasibility and utility of PRT for very young children at-risk for autism.
