Cooperation within the COST Action is organised around four closely interconnected WG’s working in parallel. The rationale for establishing the WG’s is twofold. First there is a need to exchange knowledge and expertise between the different groups that constitute an interdisciplinary approach to understanding integrated cancer prevention efforts for and with people with intellectual disabilities on many levels: co-production of a research agenda and knowledge base with people with intellectual disabilities and relevant stakeholder groups and at the level of policy making and resource provision. Second the timeline of the Working Groups is created to drive the Action towards the specified outcomes and enable coordination of European efforts in determining which way a multidisciplinary approach will be the most effective while meeting the rights of people with intellectual disabilities for equal access to healthcare in accordance with Section 25 of the UNCRPD.
