Abstract

Purpose: Bilingual children whose phonological skills are evaluated using measures designed for monolingual English speakers are at risk for misdiagnosis of speech sound disorders (De Lamo White & Jin, 2011). Method: Forty-four children participated in this study: 15 typically developing monolingual English speakers, 7 monolingual English speakers with phonological disorders, 14 typically developing bilingual Spanish–English speakers, and 8 bilingual children with phonological disorders. Children’s single-word speech productions were examined on Percentage Consonants Correct–Revised (Shriberg, Austin, Lewis, McSweeny, & Wilson, 1997a) and accuracy of early-, middle-, and late-developing sounds (Shriberg, 1993) in English. Consonant accuracy in English was compared between monolinguals and bilinguals with and without speech sound disorders. Logistic regression and receiver operating characteristic curves were used to observe diagnostic accuracy of the measures examined. Results: Percentage Consonants Correct–Revised was found to be a good indicator of phonological ability in both monolingual and bilingual English-speaking children at the age of 5;0. No significant differences were found between language groups on any of the measures examined. Conclusions: Our results suggest that traditional measures of phonological ability for monolinguals could provide good diagnostic accuracy for bilingual children at the age of 5;0 years. These findings are preliminary, and children younger than 5;0 years should be examined for risk of misdiagnosis.
