Treatment Targets in Spanish and English Bilingual Speech Intervention

Speech Intervention for Bilingual Children

Sponsor

Philip Combiths

Enrollment

16 participants

Start Date

May 8, 2024

Study Type

INTERVENTIONAL

Conditions

Speech Sound Disorder

Summary

The goal of this clinical trial is to learn which speech treatment targets result in the greatest amount of speech learning in Spanish-English bilingual children with speech sound disorders. The main questions it aims to answer are: * Does linguistic complexity of the treatment target increase the amount of generalized learning within the treated language? * Does linguistic complexity of the treatment target increase the amount of generalized speech across languages? Researchers will compare intervention effects across treatment provided in English and Spanish to see if the effect differs according to the language of intervention. Participants will: * Attend between 12 and 18 45-minute speech intervention sessions in Spanish or English for up to 6 weeks * Attend assessment visits before and after intervention * Attend follow-up assessment visits 1 month and 2 months after intervention

Eligibility

Min Age: 3 YearsMax Age: 8 Years

Inclusion Criteria3

Participants will be regularly exposed to English for at least 3 months in one of the following ways: a) an English-speaking caregiver or sibling who interacts with the child on a daily basis in English, b) attendance at an English-speaking daycare, preschool, or elementary school.
Caregivers will have reported concern with their child's speech development and/or reduced intelligibility on the Intelligibility in Context Scale in Spanish or English.
Participants will present with 5 or more consonants or clusters missing from their phonetic inventories in each language to confirm presence of a speech sound disorder and sufficient gaps in phonological knowledge to warrant treatment.

Exclusion Criteria1

Participants receiving speech or language treatment elsewhere during their participation in this project.

Interventions

BEHAVIORALSpeech Intervention

The treatment will begin with imitation, whereby the child will produce target words following the study clinician's verbal model with 1:1 clinician feedback for the accuracy of the child's productions. This will include explicit articulatory instruction (i.e., verbal and visual cues) to elicit correct target forms. When a child achieves 75% accuracy following a verbal model across 2 consecutive sessions or completes the 9th session (whichever is first), treatment will shift to spontaneous production, in which the child will produce target words spontaneously or through elicitation without a verbal model. Treatment materials will be images of treatment target words, interactive games and stories, and a standard set of toys.
