A Technology-Assisted Language Intervention for Children Who Are Deaf or Hard of Hearing: A Randomized Clinical Trial.

BACKGROUND AND OBJECTIVES: Children who are deaf or hard of hearing (DHH) often have persistent language delays despite early identification and interventions. The technology-assisted language intervention (TALI), which incorporates augmentative and alternative communication technology into a speech-language therapy model, was designed to support language learning. The study objective was to evaluate the impact of the TALI on spoken language outcomes in DHH children. METHODS: Children aged 3 to 12 years with mild to profound bilateral hearing loss were enrolled in a single-site randomized controlled trial. Children were randomly assigned to receive the TALI or treatment as usual (TAU) (with no change in current care) and were followed for 24 weeks. Primary outcomes included spoken language measures elicited from language samples. Secondary outcomes included standardized assessments. Intention-to-treat analyses were used. RESULTS: Analyses focused on 41 children randomly assigned to TALI (n = 21) or TAU (n = 20). Among all participants, mean age was 6.3 years (SD 2.5). Over 24 weeks, children in the TALI group, compared with those in the TAU group, had significantly greater increases in the length of phrases they used to express themselves (ß = .91 vs .15, respectively; P< .0001). Similar findings were seen with conversational turn-taking and number of different words spoken. CONCLUSIONS: Providing visual supports for language concepts that are typically challenging for DHH children to acquire allowed children to process and comprehend spoken language more fully. Such strategies can mitigate persistent language delays with the goal of improving lifelong outcomes and independence across settings.

Enhancing language in children who are deaf/hard-of-hearing using augmentative and alternative communication technology strategies.

BACKGROUND: Despite early identification and intervention, many children who are deaf/hard of hearing (D/HH) demonstrate significant gaps in language development which can directly impact social interactions. AIMS: The objective of this pilot study was to determine whether integrating augmentative and alternative communication (AAC) core word language strategies into a speech-language therapy program for young children who are D/HH improves spoken language outcomes. METHODS: Eleven young children, median age 5 years 7 months (range 3y;11 m to 10y;8 m) with bilateral hearing loss were enrolled in a single-case experimental design and completed a 24-week intervention that incorporated high-tech AAC strategies into a traditional speech-language therapy model (technology-assisted language intervention or TALI). The goal of the TALI was to improve spoken language development in children who were D/HH. Language samples were collected throughout the study and pragmatic language was assessed pre and post intervention. RESULTS: At the end of 24 weeks, children demonstrated a significant increase in their mean length of utterance, number of words spoken, and mean turn length according to language samples. Children also made gains in their pragmatic skills pre to post intervention. CONCLUSIONS: Results of this study suggest that using AAC core word language strategies delivered via iPad technology may support continued and rapid spoken language skill growth among young school-age children who are D/HH. By leveraging AAC technology, we are pioneering a structured and dynamic approach to language learning, building an effective foundation for concepts and grammar for children who are D/HH.

Evidenced-Based Interventions for Children With Autism Spectrum Disorder.

This paper reviews evidenced-based interventions for children with autism spectrum disorders (ASD) across the disciplines of psychology, speech-language pathology, occupational therapy, and developmental pediatrics. BACKGROUND: rates of ASD diagnoses have been steadily rising over the past 2 decades. There are a wide range of therapies and interventions, of varying levels of evidence, across disciplines that are now available to treat children with ASD. The field has moved toward a greater emphasis on the identification and utilization of evidenced-based treatments. METHODS: a review and summary of recent literature was conducted by professionals in an interdisciplinary autism center. An emphasis was placed on results of the National Autism Center's National Standards Project. RESULTS AND CONCLUSIONS: within each discipline, interventions exist that vary in level of evidenced-based support. Although disciplines may differ in their definitions of evidence-based treatments, it is important for each discipline to strive to offer and promote practices with the best evidenced-based support according to each field's standards.
