Intervention(s)

6 regions of the Community Health Service in the Netherlands, that intended to participate in the study, were randomized into 1 of the 3 research groups. In each region 1 or 2 small cities were approached on the study. In each region, about 1250 randomly selected older adults
(aged 50 or older) were informed about the project by means of an
information letter, and were asked to participate and fill in the attached first questionnaire. Furthermore, attention was paid about the project in local newspapers and in meeting points of older adults by
means of information posters.

Two tailored physical activity interventions are developed. In the first intervention condition subjects will receive tailored advice three times on their psychosocial and environmental determinants of physical activity.

The intervention will tailor on three levels:

1. awareness of physical activity;

2. behavioural change;

3. 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 tailored on physical and social environmental determinants that stimulates participation in local activities and initiatives that stimulates physical activity among older adults (sportclubs, walking and cycling routes) and to stimulate buddy systems.

The two intervention conditions will receive tailored advice at three times: two weeks after baseline assessment, 6 weeks and 3,5 months after the first baseline assessment.

During the implementation period, evaluation assessments will be taken at four times:

at the start (T0: also the data base for the first and second tailored advice), after 3 months (T1: also the data base for the third tailored advice), 6 months (T3) and after 12 months (T4).

The control group

Primary Outcome(s)

Change in physical activity behavior (0 months, 3 months, 6 months, 12 months) using a validated questionnaire (SQUASH).

Secondary Outcome(s)

Changes on awareness, intention and on determinants of initiating and maintaining physical activity behaviour (0 months, 6 weeks, 3 months) using validated questionnaires.
