Aim: This study investigated the effect of parent-implemented focused stimulation in toddlers with cleft palate ± cleft lip (CP) and delayed speech and/or language acquisition. The intervention targeted both productive vocabulary and consonant inventory directly.
Method: Participants were twenty-eight children with CP aged 16-24 months. Fourteen toddlers received intervention (INT group), and fourteen toddlers with CP constituted the control group (CONT group). The groups were matched in pairs on language development. Participants were recruited from a complete birth cohort of all 103 Danish children with CP born between December 2012 and August 2014. Video recordings of play were obtained pre-intervention and four months post-intervention. A phonological naming test was administered six months post-intervention. Reported vocabulary from parent questionnaires were obtained at all three time points. Recordings were randomized for pre and post-status and the main transcriber was unrelated to the project.
Results: Immediately after intervention, the INT group had significantly higher gain scores with large effect sizes for two outcome measures compared to the CONT group: lexical age, a measure of observed productive vocabulary, and true consonant types in words. Six months after intervention, measures of speech accuracy and reported productive vocabulary were not significantly different between the INT group and the CONT group. Toddlers with CP had significantly poorer speech accuracy than toddlers without CP, and only a few toddlers with CP performed within two standard deviations of the mean of toddlers without CP.
