Technology assisted language intervention (TALI) for children who are deaf/hard of hearing: promising impact on pragmatic skills.

Children who are deaf and hard of hearing (DHH) often demonstrate pragmatic language difficulties which can impact academic and social outcomes. This randomized control trial for DHH children, ages 3-12 years, explored the Technology-Assisted Language Intervention (TALI), incorporating augmentative and alternative communication technology (AAC) into traditional speech/language therapy, compared to treatment-as-usual (TAU) to determine impact on pragmatics. Pragmatic outcome measures included parent reported Pragmatics Profile of the CELF-5 (for children age ≥5 years) and CELF-P Descriptive Pragmatics Profile (for children <5 years) in addition to parent reported Social and Communication domains of the Vineland Adaptive Behavior Scales,Third Edition (VABS). Over 24 weeks, children ≥5 years in the TALI made significantly more progress (increase in raw scores) on the Pragmatics Profile compared to children in TAU (12.7 points vs. -6.0 points; p = 0.04) and also showed significant gains on two of the three subscales. For children ≥5 years, no significant VABS changes were seen in either intervention group. For children <5 years, there were no statistically significant differences in growth on the CELF-P total pragmatics raw score or on any subdomain. However, children in TALI had significant increases in the mean VABS Communication (86.7-99.1) and Social domain standard scores (91.8-97.4;p = 0.01), while gains for children in TAU on the Communication and Social domain standard scores were not statistically significant. These promising results support the need for additional research exploring the effectiveness of AAC supported speech/language therapy to enhance DHH children's pragmatic language skills.

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.

Language Underperformance in Young Children Who Are Deaf or Hard-of-Hearing: Are the Expectations Too Low?

OBJECTIVE: (1) To examine language performance in the context of cognitive abilities in young children who are deaf or hard-of-hearing and (2) to identify factors associated with having a language underperformance, defined as a gap between the language standard score and the nonverbal IQ (NVIQ) standard score. METHODS: Children 6 to 82 months of age with bilateral hearing loss were enrolled. Language performance was defined as a ratio of language skills relative to cognitive abilities with language underperformance defined as a ratio of language scores to NVIQ <0.85. RESULTS: Among 149 children, approximately half had hearing loss that was clinically classified as mild or moderate, and over one-third received a cochlear implant. Participants had a mean NVIQ in the average range (95.4 [20.3]). Receptive language scores were significantly lower than their NVIQ by 10.6 points (p < .0001). Among children with NVIQs 80 to 100, 62.5% had receptive scores <85 and 50% had a language underperformance (ratio <0.85). Among children with NIVQs >100, 21.1% had receptive scores <85 with 42% having a language underperformance. Children with language underperformance (n = 61, 41.5%) were more likely to have more severe levels of hearing loss, lower socioeconomic status, and be nonwhite. CONCLUSION: Many children early identified with hearing loss continue to demonstrate language underperformance, defined using their cognitive potential. Language deficits have a cascading effect on social functioning in children who are deaf or hard-of-hearing. This study highlights the need to understand a child's cognitive potential to adequately address language needs in existing intervention models.
