Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• Self-reported physical activity frequency and duration

  Participants will be asked on how many days per week they were physically active and how much time they had spent on average performing these activities on each of these days (adapted version of the Godin scale)

  two months

Secondary Outcomes (2)

• Algorithm for Stages of Change (SOC) based on behavior and intention

  two months

• Social Cognition

  two months

Study Arms (1)

Intervention

EXPERIMENTAL

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.
