Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in objective total, light and moderate-to-vigorous physical activity (PA)	Change in amount of total, light and moderate-to-vigorous physical activity, measured via accelerometers	Pretest, posttest (6 weeks) and follow-up (6 months)
Primary	Change in objective sedentary behaviour	Change in amount of total sitting time, measured via accelerometers	Pretest, posttest (6 weeks) and follow-up (6 months)
Primary	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.	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.	Pretest, posttest (6 weeks) and follow-up (6 months)
Primary	Change in self-reported sedentary behaviour	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.	Pretest, posttest (6 weeks) and follow-up (6 months)
Secondary	Change in self-efficacy	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.	Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months)
Secondary	Change in outcome expectancies	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.	Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months
Secondary	Change in risk perception	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	Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months
Secondary	Change in intention	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.	Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months
Secondary	Change in action planning	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.	Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months
Secondary	Change in coping planning	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.	Pretest, after week 1, after week 2, after week 3, after week 4, posttest (6 weeks), and follow-up (6 months
