People with intellectual disabilities have a comparatively low level of physical activity and are affected by associated numerous impairments and diseases. However, target group specific interventions and concepts aiming at sustainable physical activity-related behavior change in everyday life are rare and the needs and perspectives of the target group have hardly been considered so far. Therefore, a target-group oriented intervention was developed. The research and developmental process was characterized by a participatory approach, involving people with intellectual disabilities throughout the whole process. For example, the interview guideline, design of the interview situation and ways of communicating were developed in a participatory manner. Twenty-four qualitative interviews with people with intellectual disabilities were conducted to explore individual physical activity-related experiences and strategies. Individual and contextual influences on physical activity were identified. Interview results were used to conceptualize an intervention that aims at promoting physical activity in the everyday life of people with intellectual disabilities by strengthening their self-management strategies. The intervention was tested in practice and modified based on communicative validation methods. Good acceptance in the long term is also expected, as the intervention takes place in people's living environment, is socially embedded and builds upon the needs of the target group.
