Support Staff-client Interactions With Augmentative and Alternative Communication

Completed
Conditions
Intellectual Disability
Registration Number
NCT02099773
Lead Sponsor
Universitaire Ziekenhuizen KU Leuven
Brief Summary

This exploratory and observational study focuses on adults with an intellectual disability (ID) and their support workers. Two groups of clients are observed: clients using Key Word Signing, and clients using aided Augmentative and Alternative Communication (AAC). Approximately half of adults with ID is estimated to experience communication difficulties. AAC supports them in their daily communication aiming at optimal participation in society. Current communication models, such as Participation Model (Beukelman \& Mirenda, 2005) and International Classification of Functioning, Disability and Health (WHO, 2001), regard both client-related and environmental factors as important elements of communication. A substantial part of the environmental factors is made up of the communication partners' characteristics. In daycare and residential services for adults with ID the support worker is an important communication partner .

Detailed Description

This study aims to:

1. with regard to teaching Key Word Signing (KWS), a specific form of AAC, to support workers:

Analyse the relation between training method, support workers' attitude, and short and long term sign knowledge.

2. with regard to the use of manual signs in everyday communication between support workers and adults with ID:

* Identity the support workers' characteristics that may influence the quality/quantity of the communication between adults with ID who use manual signs and their support worker.

* Analyse the nature of this influence as well as any possible interaction effects with the clients' characteristics.

3. Assess whether an existing instrument, designed for measuring interactions between parents and children with cerebral palsy using AAC, may be used with adults client and support workers.
