Brief Summary

In the United Kingdom, the language of the Deaf community is British Sign Language (BSL). A small proportion of Deaf young people who use BSL as their first or dominant language have specific language difficulties and would benefit from language therapy provided in sign language by adults who are fluent in BSL and may be Deaf. Some Deaf adults are currently employed in education and health services to support children's BSL development. However there is little training or information available to these adults about language assessment, diagnosis of language difficulties or intervention strategies.

Recent studies have highlighted language difficulties and therapy in sign as an issues and begun to explore Deaf adults understanding of language difficulties and disorder. This project aims to extend knowledge in this area by supporting Deaf practitioners to understand and develop language therapy skills and co-develop language therapy intervention resources. The study will pilot training for practitioners and language therapy interventions for young people.

Detailed Description

The study will be in three phases. The design has been discussed at regular Language Working Group Meetings with Deaf practitioner colleagues who may want to volunteer to be involved in the project.

In Phase 1, information will be sought from Deaf practitioners in focus groups and from questionnaires about the strategies and resources they currently employ when working with Deaf young people with language difficulties. This information will be compared to evidence based models of therapy for spoken English to see whether similar themes emerge. The findings will also be used to identify themes for other strategies and resources Deaf practitioners use which are not present in spoken English language therapy. The data gathered will be included in planning the next phase of the project. Scenarios and questions similar to those planned for the focus group and questionnaire have been trialed at Service training days and feedback has been gathered from staff involved.

Phase 2 will involve working with Deaf practitioners to develop and define strategies and resources for language therapy in BSL. These will be with a small group of three or four Deaf practitioners. Dynamic assessment and mediated learning principles will be used to identify key skills and resources for Deaf practitioners in providing language therapy.

This process, including pre and post involvement questionnaires, will use video observation and reflective practise tools. Analysis of a language therapy intervention session by a Deaf practitioner will provide a snapshot or 'assessment' of their initial skills and knowledge. Then, over a period of six sessions, videos of the Deaf practitioner working with a young person on language activities will be jointly analysed and reflected upon to identify strategies and resources that are or would be useful in this working context. This joint analysis between the researcher, a qualified Speech and Language Therapist, and the Deaf practitioner will provided teaching, learning and reflection opportunities. Finally the video analysis by the Deaf practitioner, without reflection with the researcher, will be repeated to give a second 'assessment' of the Deaf practitioner's skills and knowledge. The Deaf practitioner will be asked to give feedback on this process, identifying helpful strategies discussed, issues with the process and information they feel would be useful to other Deaf practitioners completing similar work with young people. Deaf practitioners will work with deaf young people who are currently on their clinical caseload and have previously been identified as having language difficulties. These young people and their families will be informed about the project and, if they consent to participate, will participate in the six sessions led by the Deaf practitioner.

The information gained from this process will identify useful strategies and resources. Validation will be sought by comparing evidence based language therapy strategies and resources from spoken English with those identified by Deaf practitioners in Phase 1 and those found to be useful by Deaf practitioners in Phase 2. These will be used to develop a training package containing strategies, resources and guiding principles for Deaf practitioners using BSL for language therapy delivery.

In phase 3, single case studies will be undertaken. These will include training other Deaf practitioners to use strategies and resources with Deaf young people. Qualitative information from Deaf practitioners and young people, as well as quantitative information from pre and post intervention language assessments and sample video clips, will be analysed to ascertain whether the training in strategies and resources enables Deaf practitioners to use identified intervention strategies and develop the language skills of Deaf young people. The qualitative data will be gathered through the use of reflective logs and questionnaires. The quantitative data will be gathered through the use of structured language assessment activities. Young people and their parents will also provide qualitative information about the process through questionnaires or interviews, depending on their communication mode (English, another spoken language or BSL) and their preference.
