What this study means for families

Researchers studied whether Pivotal Response Treatment (PRT) could help autistic children improve their communication skills. Thirty children were split into two groups - one received PRT training for 8 weeks while continuing their usual school program, the other only received their usual school program. Parents in the PRT group were also trained. Children who received PRT showed better improvements in asking for things, naming objects, repeating words, and responding to others.

These improvements lasted over time and also helped with social skills, thinking abilities, and daily living skills.

Research summary

This randomized controlled trial examined Pivotal Response Treatment (PRT) effectiveness for improving language functions in 30 autistic children in special schools. Participants were randomly assigned to receive either 8 weeks of PRT motivation training plus treatment as usual, or treatment as usual alone. Parents in the PRT group received training to practice procedures at home. The PRT group showed greater improvements across four primary language functions (requesting, labeling, repeating, responding) based on Skinner's verbal behavior theory.

Benefits were maintained at follow-up and generalized to untargeted areas including social communication, cognition, motor skills, imitation, and adaptive behaviors. The study demonstrates PRT's potential for comprehensive developmental improvements beyond targeted language outcomes.

Clinical implications

PRT motivation training shows promise as an effective language intervention for autistic children in educational settings. The generalization to untargeted skills suggests broader developmental benefits. Parent training component may enhance treatment effectiveness. Findings support PRT implementation in special schools with family involvement for comprehensive language and social communication improvement.

Limitations

Small sample size (n=30) limits generalizability. Study conducted specifically in special school settings may not translate to other environments. Abstract lacks details about outcome measures, effect sizes, and specific follow-up timeframes. Control group design unclear regarding blinding procedures.

Original abstract

Language difficulties exert profound negative effects on the cognitive and social development of autistic children. Pivotal Response Treatment (PRT) is a promising intervention for improving social communication in autistic children, but there is a lack of a comprehensive examination of language functions. This study aimed to investigate the effectiveness of PRT in promoting the primary language functions (requesting, labeling, repeating, responding) defined by (Skinner, B. F. (1957).

Verbal behavior. Martino Publishing.) theory of verbal behavior in autistic children. Thirty autistic children were randomly divided into the PRT group (M = 6.20, SD = 1.21) and control group (M = 6.07, SD = 1.49). The PRT group were provided with an 8-week training of the PRT motivation component in addition to treatment as usual (TAU) in their schools, whereas the control group only received TAU.

Parents of the PRT group were also trained to practice the PRT motivation procedures at home. The PRT group demonstrated greater improvements in all four measured language functions compared to the control group. The improvement in language functions in the PRT group was generalized and maintained at the follow-up assessment. In addition, the PRT intervention enhanced untargeted social and communicative functioning, cognition, motor skills, imitation, and adaptive behaviors in the autistic children.

In conclusion, language intervention using the motivation component of PRT is effective in promoting language functions as well as widespread untargeted cognitive and social functions in autistic children.
