title: Underlying manifestations of developmental phonological disorders in French-speaking pre-schoolers.
abstract: This study examined the psycholinguistic profiles of Quebec French-speaking children with developmental phonological disorders (DPD). The purpose was to determine whether the endophenotypes that have been identified in English-speaking children with DPD are similarly associated with speech impairment in French-speaking children. Seventy-two children with DPD and ten children with normally developing speech, aged four to six years, received a comprehensive assessment battery that included measures at the phenotype level (i.e. measures of overt speech production skills) and endophenotype level (i.e. measures of potential underlying core deficits such as phonological processing or oral motor impairments). The majority of the children with DPD presented with a psycholinguistic profile indicative of difficulties with phonological processing. Phonological processing skills also explained unique variance in speech production accuracy, indicating that French-speaking children with DPD, who produce different surface speech errors than English-speaking children with DPD, are nonetheless very similar with regards to their underlying psycholinguistic profile.
