Brief summary

The aim of this study is to investigate the effectiveness of intervention 'MyPlan 2.0' and the efficacy of the different behaviour change techniques that are included. Eight groups will be created that will receive a different version of the intervention, varying in three behaviour change techniques (action planning, coping planning, self-monitoring).

Detailed description

The effectiveness of the self-regulation-based e- and m-health intervention 'MyPlan 2.0' on changing physical activity and sedentary behaviour in the adult population will be investigated. Furthermore, the role of three different behaviour change techniques (action planning, coping planning, self-monitoring) will be examined via a 2x2x2 design, in which 8 groups are created that all receive a different version of the intervention.

Interventions

BEHAVIORALAction planning

Action planning is the behaviour change technique used to make users specify their goal (what they are going to do, when, where, ...).

BEHAVIORALCoping planning

Coping planning is the behaviour change technique used to make users think about possible hindrances and according solutions when trying to reach their goal.

BEHAVIORALSelf-monitoring

Self-monitoring is the behaviour change technique used to make users keep track of their goal.

BEHAVIORALFeedback and tips

In this intervention, users receive tailored feedback on their current health behaviour and tips and tricks to reach their goals. This tips and tricks include the behaviour change technique 'eliciting social support'.
