Abstract

This study aimed to directly compare the effectiveness of Pivotal Response Training (PRT) and Video Modeling (VM) in the acquisition and generalization of scripted play verbalizations and actions as well as the use of novel statements or actions in both the training and generalization settings. All five participants were exposed to both conditions and were randomly assigned to the sequence of treatment conditions: participants in Sequence 1 received Condition 1 (VM) followed by and Condition 2 (PRT); participants in Sequence 2 received Condition 2 followed by Condition 1. Results showed a significant increase in the number of play actions for both the PRT and VM conditions in the training environment, with greater increases evident as a result of PRT. Significant increases were also found in the number of play actions in PRT compared to VM in the generalization environment.

Inclusion criteria for participation and measures

Inclusion criteria were set to ensure that the participants had adequate language ability to commence instruction in pretend play skills. All participants were required to have a similar language ability to typically developing children age two years of age given that it is in the second year of development that pretend play skills emerge. Secondly, measures of autism severity and play skills were taken to verify that there were no differences between the participants on these variables prior

Preliminary analysis

Independent t-tests were conducted to examine differences between participant's baseline assessments of age, IQ, verbal comprehension and naming vocabulary, level of autism severity and the five types of play measured using the PPBS: reticent play, solitary-passive play, solitary-active play, social play, and rough and tumble play. For participant characteristics see Table 1.

No significant difference was found between age, IQ test scores, verbal comprehension, naming vocabulary and autism

Discussion

Results of the current study found that children with ASD who have sufficient language skills can increase their pretend play skills through Pivotal Response Training and Video Modeling. The results show that Pivotal Response Training had a significant increase in the number of play actions emitted by the participants in the follow-up probe compared to the baseline probe in the training environment. In this condition participants showed a mean difference between probes of 11.6 actions.

      Also, in the current study, we evaluated behavior at one and two months post intervention and found the treatment results durable and generalized to novel contexts. Others have reduced inflexible behavior using direct contingencies of reinforcement (Brodhead et al., 2014; Lydon et al., 2011; MacDonald et al., 2009). These procedures show promise, but it is of interest that in the current study, the ACTraining intervention strategies were faded after a few sessions prior to maintenance and generalization probes.

      Several approaches have been used successfully to promote diverse play skills in children with ASD. Briefly, these include video modeling (D’Ateno, Mangiapanello, & Taylor, 2003; Dauphin, Kinney, & Stromer, 2004; Lydon, Healy, & Leader, 2011), pivotal response training (Lydon et al., 2011; Stahmer, 1995; Vismara & Lyons, 2007), matrix training (Dauphin et al., 2004), integrated play groups (Wolfberg & Schuler, 1993), social stories (Barry & Burlew, 2004), and milieu-based interventions (Kasari et al., 2006, 2008). Pairing tangible and social reinforcement might work to increase declarative ICAs by increasing the value of attention as a reinforcer.
