Abstract
This study investigates the factors that influence satisfaction, behaviours and intentions of university students. Participants will be put in groups and will spend about 30 minutes on completing this study. They will need to answer a questionnaire, which consists of questions regarding their experiences at Warwick, as well as their intended involvement in health behaviours.

I will also conduct robustness check to make sure results are credible and reliable.
