Stage-based Exercise Promotion Study (STEPS)
The purpose of this study is to increase regular physical activity among students by fostering self-management competencies. The intervention was implemented as paper-pencil intervention. The aim of this research project is to evaluate a motivational and volitional intervention in comparison to a control intervention.
Study participants will be recruited in lectures at Freie Universitaet Berlin and followed up twice (two and ten weeks after baseline).
The motivational intervention is expected to increase unmotivated participants' intention to be physically active. The volitional intervention is expected to promote physical activity among motivated but inactive participants. Both interventions are hypothesized to improve self-management competencies over time.

Detaljert beskrivelse
An experimental study is planned over a time period of ten weeks. In the physical activity study, participants will randomly be allocated to either one of two intervention groups (IG) or to an active control group (ACG), receiving a quiz on physical activity and sports. Intervention group 1 receives a paper-pencil intervention which focuses on positive outcome expectancies (motivational intervention). Intervention group 2 receives a paper-pencil intervention which promotes the formulation of action plans for physical activity (volitional intervention).
Furthermore, all participants will receive two emails as intervention boosters until the end of the study.
Study participants will be invited to take part in the study during lectures of the Freie Universitaet Berlin. The students will be followed up twice: two weeks after T1 (paper-pencil), T2 will take place (paper-pencil). Eight weeks after T2 the T3 assessment will be conducted online.
The hypotheses are:
Participants of the motivational intervention report a larger increase in motivation to adopt physical activity from T1 to T2 and T3, as compared to the participants of the volitional or the control intervention. Effects will be larger in unmotivated participants than in already motivated participants.
Participants of the volitional intervention report a larger increase in physical activity from T1 to T2 and T3, as compared to the participants of the motivational or the control intervention. Effects will be larger in motivated participants than in unmotivated participants.

Participants will be allocated to a motivational intervention, a volitional intervention or the active control group. The motivational intervention promotes positive outcome expectancies on physical activity. The volitional intervention promotes the formulation of action plans for physical activity. Participants in the active control group, receive a quiz on physical activity and sports. |
