Abstract
Objective: This study describes a preliminary evaluation of the construct and concurrent validity of the Speech Intelligibility Probe for Children With Cleft Palate. Design: The study used a prospective between-groups design with convenience samples. Participants: Participants (ages 39 to 82 months) included 5 children with cleft palate and 10 children with typical speech development and no history of craniofacial abnormalities. All children had age-appropriate language skills. Interventions: Each child completed the Speech Intelligibility Probe for Children With Cleft Palate by imitating single words. Each child's word productions were recorded and played back to listeners who completed open-set and closed-set response tasks. Recorded utterances that represented a contiguous 100-word sample of each child's spontaneous speech also were played back to listeners for completion of an open-set word identification task. Main Outcome Measures: Measures reported include group means for (1) intelligibility scores for the open-set Speech Intelligibility Probe for Children With Cleft Palate and spontaneous speech sample conditions, and (2) percentage of phonetic contrasts correct and correct-distorted from the Speech Intelligibility Probe for Children With Cleft Palate closed-set response task. Results: The group of children with cleft palate had significantly lower intelligibility scores, lower percentage of correct phonetic contrasts, and higher percentage of correct distorted items (construct validity). A strong positive correlation (r = .88, p < .01) was found between intelligibility scores from the Speech Intelligibility Probe for Children With Cleft Palate and the spontaneous sample (concurrent validity). Conclusions: The results provide preliminary support for the construct and concurrent validities of the Speech Intelligibility Probe for Children With Cleft Palate as a measure of children's speech intelligibility.Keywords
