The use of guided self-help for people with intellectual disabilities to treat depression and/or anxiety is in its infancy. The SAINT (Self-Assessment and INTervention) is the first resource to be made commonly available which has been developed specifically for people with intellectual disabilities. Using colour photographs and easy read text, the SAINT offers a structured and accessible way to deliver guided self-help with this population. By using a daily diary, clients can learn to recognise their emotions and develop ways to cope with them. This facilitator manual explores the role of guided self-help, its evidence base and its role in treating anxiety and depression. It details the development of the SAINT and the rationale for its use, and offers experiences from individuals who have used it in their own lives. The manual will help a facilitator to prepare for sessions with a client who is using the SAINT.
