Exploring Input Parameters in an Expressive Vocabulary Treatment With Late Talkers.

ABSTRACT: Purpose The aims of this study were (a) to assess the efficacy of the Vocabulary Acquisition and Usage for Late Talkers (VAULT) treatment and (b) to compare treatment outcomes for expressive vocabulary acquisition in late talkers in 2 conditions: 3 target words/90 doses per word per session versus 6 target words/45 doses per word per session. Method We ran the treatment protocol for 16 sessions with 24 primarily monolingual English-speaking late talkers. We calculated a d score for each child, compared treatment to control effect sizes, and assessed the number of words per week children acquired outside treatment. We compared treatment effect sizes of children in the condition of 3 target words/90 doses per word to those in the condition of 6 target words/45 doses per word. We used Bayesian repeated-measures analysis of variance and Bayesian t tests to answer our condition-level questions. Results With an average treatment effect size of almost 1.0, VAULT was effective relative to the no-treatment condition. There were no differences between the different dose conditions. Discussion The VAULT protocol was an efficacious treatment that has the potential to increase the spoken vocabulary of late-talking toddlers and provides clinicians some flexibility in terms of number of words targeted and dose number, keeping in mind the interconnectedness of treatment parameters.

Project description:Several qualitative and quantitative features of parental speech input support children's language development and may play a critical role in improving such process in late talkers. Parent-implemented interventions targeting late-talkers have been developed to promote children's language outcomes by enhancing their linguistic environment, i.e., parental speech input. This study investigated the effect of a parent-implemented intervention in increasing late talkers' expressive skills through modifications in structural and functional features of parental speech input. Forty-six thirty-one-month-old late talkers differing in their birth condition (either low-risk preterm or full-term) participated in the study with a parent; 24 parent-child dyads received a parent-implemented intervention centered on dialogic reading and focused stimulation techniques, whereas the other 22 dyads constituted the control group. At pre- and post-intervention, dyads took part in a parent-child shared book-reading session and both parental and child's speech measures were collected and examined. Results showed that the intervention positively affected parents' use of responses and expansions of children's verbal initiatives, as well as the parental amount of talking over reading, whereas no structural features of parental input resulted modified. Mediation analyses pointed out that the intervention indirectly enhanced late-talkers' use of verbal types and tokens through changes in parental use of expansions and amount of talking over reading. As birth status was entered as a covariate in the analysis, these findings can be extended to children with different gestational age. We conclude that the parent-implemented intervention was effective in supporting late-talkers' gains in language development as a cascade result of the improvements in parental contingency and dialogic reading abilities. These promising findings suggest to examine not only children and parental outcomes but also the intervention mechanisms promoting changes in late-talkers' language development as a clearer view on such process can inform the development of feasible, ecological and effective programs.
