A Comparative Analysis of Parent–Child Interaction Therapy Procedures Used to Facilitate Verbalizations by Children with Autism
Repeating the child’s own sounds during play drives the biggest language jumps in PCIT for minimally verbal preschoolers with autism.
01Research in Context
What this study did
The team compared three parent talking tactics during play sessions. Parents first added labeled praise and described what the child was doing. Later they also repeated or re-cast the child’s sounds and words.
Each family moved through the steps only after the child met a set goal. The design tracked the same kids across time so the order of tactics could be linked to changes in talking.
What they found
Labeled praise plus behavior descriptions lifted the number of words the children said. When parents added reflections, the gains sped up and the kids used more different words.
Reflections gave the biggest jump for preschoolers who had very few words at the start.
How this fits with other research
Haebig et al. (2013) showed that parents who follow their child’s focus of attention boost later receptive language. Barnes Ross et al. now add that repeating the child’s own sounds speeds expressive growth.
Capio et al. (2013) found that parent coaching aimed at social play improved interaction but did not lift language scores. The new study says the difference is in the tactic: reflections, not just social coaching, drive talking gains.
Li et al. (2015) showed parents can master strategies quickly for minimally verbal school-aged kids. The current work extends that idea downward to preschoolers and names the key move—reflect what the child just said.
Why it matters
If you coach parents of minimally verbal preschoolers, teach them to echo and expand the child’s sounds right in play. Start with labeled praise and descriptions, then add reflections for the fastest language boost.

03Original abstract
AbstractThe current study conducted a comparative analysis of the effects of select components of Parent–Child Interaction Therapy, labeled praise, behavior descriptions, and reflections on child vocalizations in two children with autism spectrum disorder and accompanying language delays using a concurrent multiple baseline across participants design. The frequency of verbalizations, the frequency of different verbalizations, and the mean length of utterance of words (MLUw) were measured during a baseline condition followed sequentially by two experimental conditions during a free play environment. The total number of therapist–child interactions remained consistent across all experimental conditions such that only the topography of the interactions varied across conditions. During the first experimental condition the clinician used labeled praise and behavior descriptions during child play. After establishing stability of changes under these conditions, the therapist systematically added reflections of child vocalizations in the second experimental condition. Total verbalizations, different verbalizations, and MLUw increased following the introduction of labeled praise and behavior descriptions. Total verbalizations and different verbalizations increased and the frequencies accelerated following the systematic introduction of reflections. The study showed the relative value of reflections of child verbalizations as a powerful component of Parent–Child Interaction Therapy procedures to facilitate verbalizations by children with autism.
