Adult recasts as fluency-facilitators in preschoolers who stutter: Evidence from FluencyBank

Adult conversational recasts are based on child platform utterances that contain errors (e.g., Child: “Me going.” Adult: “Yes, you are going”), and recasts are effective in the child language literature. For many years, adult recasts of preschoolers’ stuttered utterances were surmised as fluency-facilitating, but to date, no evidence has been reported to support their efficacy. The purpose was to investigate the natural occurrence of, and the fluency-facilitating potential of, recasts produced by caregivers and clinicians/examiners in free-play interactions transcribed from audio or video recordings on FluencyBank. Forty-three participants with a median age of 38 mo (3;2) (Range=28–73 mo), including 32 boys and 11 girls were selected from five databases, and recasts which were near-imitations and simple recasts as per Weiss (2002) were identified. One database chosen was the Illinois project, to include a subgroup of persistent (n = 9) and recovered children (n = 9). In the 43 participants, significantly (p < 0.0001) fewer stutters and lower percent syllables stuttered (%SS) were observed in post-recast utterances (4%SS) as compared to post-nonrecast utterances (12.5%SS). The CWS-persistent subgroup (n = 9) did not fit the group trend of the 34 others who significantly differed in stuttering frequency post-nonrecast versus postrecast. Findings are taken to mean that adult conversational recasts of preschoolers’ stuttered utterances are fluency-facilitating, and interpretations are addressed.
