The White Paper "Valuing People" [Department of Health (DoH) (2001) "Valuing people: a new strategy for learning disability for the 21st century," London, HMSO] indicates that people with a learning disability need to become more actively involved in the decisions that affect their lives. This includes being offered active choices in access to health services. Psychologists, therefore, need to think about how to give people with learning disabilities enough relevant information in an accessible way to promote informed consent to treatment. This study investigates how much information adults with mild and moderate learning disabilities understand about psychology services, before and after watching a video designed to explain what seeing a psychologist entails. The video was shown to 19 participants at a local Social Education Centre. Participants' knowledge increased significantly after watching the video. They were able to answer questions about its content better when asked after short sections of the video when presented, rather than after an uninterrupted presentation.
