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 Altenrative 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 .
