Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The mindfulness app that will be used is Headspace, a commercially available app. The questionnaires will be delivered via computer or mobile phone, and the mindfulness content will be delivered via mobile phone. The content within the app is delivered via audio files and streamed video demonstrations. The intervention will be 6 weeks in duration and participants are requested to complete 30 meditation sessions (an average of 5 per week) during this time. Each session lasts 10-15 minutes. The content of the sessions focus on introducing the concept of mindfulness, practical tips for practicing mindfulness meditation and a guided body-scan meditation. Later sessions introduce a breath counting exercise during the guided meditations and develop a greater emphasis on non-judgmental awareness. This content was developed and delivered by Andy Puddicombe who is an internationally recognised expert in mindfulness practice and teaching. Objective adherence data will be collected through the Headspace accounts of the participants. The following data will be collected from the Headspace app: Pack name (e.g. Basics); session number (e.g. 1), time and date stamp for each completed session; session duration; platform the session was completed on.

Statistical methods / analysis
A meta-analysis of 15 online mindfulness- based interventions showed that for the outcome of stress, mindfulness had a moderate effect size (g=0.51) (Spijkerman et al., 2016). For the current study, power was set at 0.80 to detect a moderate effect size (f2 = 0.50) at a significance level of p < .05. Based on a repeated measures ANOVA test, this would require a sample size of 63 participants in each condition, with a total sample size of 126. Taking into account an anticipated dropout rate of 40%, the recruitment target will be set to 178 participants. Quantitative data will be analysed using SPSS software, version 23. App usage information will be descriptive only. Changes in pre- and postintervention scores between treatment conditions for measurements of stress, depression, anxiety, sleep quality, mindfulness and self-efficacy subscales will be assessed using analysis of variance (ANOVA). The primary outcome will be a self-reported measure of stress assessed using the Perceived Stress Scale.

Summary
Brief summary
Aim: To deliver and evaluate a Mindfulness App (Headspace) in the student population.
Study design: This study will be a pilot randomised controlled trial with a waitlist control condition. There will be three measurement occasions: pretest, 6-week post-test, and 3-month follow-up, and they will receive 3 reminder text messages to complete the questionnaires on these 3 occasions.

Hypotheses: It is hypothesised that students receiving the Headspace app will have greater reductions in anxiety, depression and stress when compared to the control. App users will also show greater improvements in sleep quality, academic achievement, mindfulness, and self-efficacy.
