Brief Summary

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.

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.

Arm && Interventions

Group	Intervention	Description
Waiting List control group	Waiting List	Participants will not receive the e- and mHealth intervention 'MyPlan 2.0', but will be given access to the intervention after all testing phases.
Intervention group	MyPlan 2.0	Participants will receive the e- and mHealth intervention 'MyPlan 2.0'.

Primary Outcome Measures

Name	Time	Method
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 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 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 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 Outcome Measures

Name	Time	Method
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 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 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 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 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.
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.
