Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Mobile mindfulness-based app intervention for weight loss using mindfulness based stress reduction techniques (e.g body scan, Hatha Yoga, walking and sitting meditation, and breathing exercises) and mindful eating techniques. The app will also have basic educational information on basic dietary and physical activity guideline information from The WHO guidelines on Physical activity and dietary intake.The app will be compatible with iPhone and android. The mobile app will enable mindful eating and minduflness-based stress reduction text messages to be sent as push notifications. It will further have written educational information, mindfulness meditation and yoga videos, meditation audios, photos that inspire mindfulness, and an electronic diary for self-monitoring of mindfulness activities. Push notifications will also be sent at a frequency of 1-2 per week. To ensure students are motivated, they will receive text messages during the final 3 weeks of the study (1) per week to motivate them extra to use the app beyond the push notifications near the high stress busy exam period.
Mode of Delivery: by Mobile Phone
Duration: 11 weeks
Location: University of Queensland St Lucia and Herston Campuses
Post intervention focus groups will be conducted to learn about experiences with the app and any attitudinal changes towards meditation and a healthy lifestyle.

Efficacy
Statistical methods / analysis
Analysis of covariance ANCOVA will be used to assess weight changes and weight related behaviours from baseline to follow-up between the intervention and control groups.

As this will be the first mobile mindfulness-based text message intervention for weight loss, there are no previous effect sizes that may give a precise same size calculation. However, an estimate was based on likely effects including related mHealth studies . Assuming a moderate effect size with alpha =0.05 and 80% power to detect a difference, a sample size of 58 would be required for 10% drop out and 66 would be required to account for 20% drop out. This trial will aim to recruit over 58 participants, with the aim of recruiting more to take into account a possibly weaker effect size (doubling).
