Intervention Efficacy: What does intervention really look like?
With the advent of universal newborn infant screening, many children with hearing loss are able to attain speech and language skills commensurate to age-matched hearing peers. Therapy targeting speech, language, and/or auditory skills is typically a component of treatment program during the birth to 3 years. This study is an initial investigation into quantitatively describing the characteristics of this intervention using LENA (Language Environment Analysis). The preschool setting and therapy setting will be discussed.
The first study demonstrates benefit of access to summer preschool services for children with hearing loss. In general, it is difficult to demonstrate language change over a short period of time on standardized tests that are designed to be administered annually. However, use of LENA proved to be a powerful tool in documenting the language environment of the preschool and home. Within a single day, the language stimulation that occurred during the preschool experience was equivalent to the average language stimulation that a hearing child is exposed to in a 10-16 hour day. For the children in the most enriched home language environments, preschool allowed them to double their amount of access to spoken language and that in turn, doubled their conversational turns and their child vocalizations. Results indicate that summer educational programs can significantly increase amount of language exposure.
The second study uses LENA and demonstrates that it is a promising tool to characterize therapy sessions by number of adult word count, child word count, and conversational turns of a therapy session. Two specific models with preliminary data will be presented. First, we will consider the characteristics of a master clinician as compared to a novice clinician. Second, we will consider whether LENA can quantify the impact of continuing education.
- Participants will be able to describe how LENA (Language Environment Analysis) can be used to quantify intervention.
- Participants will be able to consider whether LENA (Language Environment Analysis) may be a useful tool for evaluating or measuring program improvement within their own state.
