Intervention
Two tailored physical activity interventions are developed. In the first intervention condition subjects will receive tailored advice three times on their psychosocial and environmental determinant of physical activity. The intervention will tailor on three levels: awareness of physical activity, behavioural change and maintenance of behavioural change.
In the second intervention condition subjects will receive tailored advice three times on their psychosocial determinants of physical activity and in more details on environmental determinants.
Additionally, there will be an extra intervention to stimulate participation in local activities that stimulate physical activity among the over-50s.
The two intervention conditions will receive tailored advice at three times: 2 weeks after baseline assessment, 1 month and 2 months after the first baseline assessment. During the implementation period, evaluation assessments will be taken at three times: at the start (T0: also the data base for the first and second tailored advice), after 1.5 months (T1: also the data base for the third tailored advice), and after 3 months (T2).
