Detailed description
The aim of this study is to investigate whether and how 'MyPlan 2.0' helps older adults to be more physically active or less sedentary. Two groups will be created, an intervention group and a waiting-list control group. Both groups will be tested during three testing waves: pretest, posttest and follow-up test. Only the intervention group will be given acces to 'MyPlan 2.0'. 'MyPlan 2.0' consists of a website and mobile application targeting physical activity and sedentary behaviour. The intervention has a duration of five weeks.
Interventions
BEHAVIORALMyPlan 2.0
MyPlan 2.0 consists of five sessions. During these five sessions the following behaviour change techniques are used to motivate users to be more physically active or to sit less: exploring risk perceptions and perceived benefits, exploring social support, providing feedback, action planning, coping planning and monitoring.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in objective total, light and moderate-to-vigorous physical activity (PA) | Pretest, posttest (6 weeks) and follow-up (6 months) | Change in amount of total, light and moderate-to-vigorous physical activity, measured via accelerometers |
| Change in objective sedentary behaviour | Pretest, posttest (6 weeks) and follow-up (6 months) | Change in amount of total sitting time, measured via accelerometers |
| Change in self-reported total, moderate and moderate-to-vigorous physical activity (PA) as well as total work-related, transport-related, household-related and leisure time PA. | Pretest, posttest (6 weeks) and follow-up (6 months) | Change in amount of total, light and moderate-to-vigorous PA well as total work-related, transport-related, household-related and leisure time PA will be measured via the International Physical Activity Questionnaire (IPAQ). The IPAQ measures physical activity in four domains: work, transport, household and leisure time. Higher scores indicate higher levels of physical activity. For each scale the minimum value is 0. We will use the method described by Dubuy et al. (2013) to truncate the data. |
| Change in self-reported sedentary behaviour | Pretest, posttest (6 weeks) and follow-up (6 months) | Change in amount of total sitting time, measured via the LASA sedentary behaviour self-report questionnaire. The total score is calculated by summing all 10 items.The minimum value is 0 and the maximum value is 24 hours. However, data will be truncated at 16 hours. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in action planning | Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months | Amount of action planning for behaviour change, measured via 3 validated items (questionnaire). These items were created by the involved research groups. For each item, the scale ranges from 1 to 10. The average score on the three items will be considered the final score. |
| Change in self-efficacy | Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months) | Change in amount of self-efficacy to change behaviour, measured via 5 validated items (questionnaire). These items were created by the involved research groups. For each item, the scale ranges from 1 to 10. The average score on the five items will be considered the final score. |
| Change in coping planning | Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months | Amount of coping planning for behaviour change, measured via 3 validated items (questionnaire). These items were created by the involved research groups. For each item, the scale ranges from 1 to 10. The average score on the three items will be considered the final score. |
| Change in outcome expectancies | Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months | Outcome expectancies regarding the behaviour change, measured via 5 validated items (questionnaire). These items were created by the involved research groups. For each item, the scale ranges from 1 to 10. The average score on the five items will be considered the final score. |
| Change in risk perception | Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months | Risk perception about the behaviour, measured via 4 validated items (questionnaire). These items were created by the involved research groups. For each item, the scale ranges from 1 to 10. The average score on the four items will be considered the final score |
| Change in intention | Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months | Amount of intention to change the behaviour, measured via 3 validated items (questionnaire). These items were created by the involved research groups. For each item, the scale ranges from 1 to 10. The average score on the three items will be considered the final score. |
