Study type
Description of intervention(s) / exposure
The Smiling Mind app targets three primary areas of daily functioning: stress reduction, increase sleep quality, and reduced loneliness. The users are able to choose which program (or all) they would like to register for.
Once participants complete the consent form and baseline assessment (via online platform: REDcap), they will be randomised in to one of two conditions: waitlist/control group, or app treatment group. Respondents randomised to the app treatment group get sent an email with instructions on how to download and get started with the programs (of their choice).
The activities in the app includes audio guided meditations, which the participants are encouraged to engage with every day, however, the minimum number of meditations required is five over two weeks. The intervention duration is four weeks in total, with the baseline assessment given to participants at two weeks and four weeks.
Before the two- and four-week assessments are sent to participants in the treatment group, research team members from Smiling Mind (listed and approved on ethics) will check the registration and engagement in the app via the email address provided by the participant.
Participants allocated to the waitlist/control group will be asked to declare any engagement in mindfulness meditation at the beginning of the two- and four-week online surveys. Declaration of engagement deems them ineligible to continue with the project.
All participants who complete all three assessments go into the draw to win a $100 Amazon voucher, emailed to them at the conclusion of the project.

Comparator / control treatment
The control/waitlist group will be 50% of the trial participants and will be given access to the Smiling Mind mindfulness application after the four weeks of the research study. The waitlist group will complete intermittent and four-week online assessments (same as the intervention group).

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The randomisation model is completed by a statistician who is not involved in the recruitment or analysis of data for this project.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be completed using an excel spreadsheet which will be uploaded to a researcher specific survey collection database (REDcap).
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?

Not Applicable
Type of endpoint(s)
Statistical methods / analysis
200 participants to complete the baseline survey (100 in each group) to retain 62 per group at follow-up to detect a moderate effect size difference between groups on the stress scale at follow-up assessment. This accounts for a 35% attrition rate.

The outcomes will be tested using ANOVA and if appropriate ANCOVA (i.e. if one or demographic variables have an influence on the participant outcomes). Descriptives and frequencies will also be analysed to test differences between groups within each treatment condition.

Brief summary
This study is a randomised controlled trial, comparing the participation in a Smiling Mind program with a waitlist/control group. Participants will be recruited through facebook and will be given the participation information statement outlining the research. Those agreeing to participate will be redirected to the initial survey (baseline data collection) which will be generated through REDcap survey software. Once the survey is complete participants will be
randomised to either the waitlist/control group, or participation in a Smiling Mind program of their choice (sleep, relationships, or stress). Participants allocated to the waitlist group will receive an email with detailing that they will need to wait to join the program. Participants allocated to participate in the program will be sent instructions for joining the program. Participants will be asked to complete the initial survey (minus questions asking about
demographics, and their experience with mindfulness practice) at two more time points: two weeks (half way), and four weeks (conclusion of the program).
The data collected from the surveys at each time-point will be analysed to assess if there is a difference between the experimental and control groups. As an incentive to complete follow up surveys participants who complete all of the surveys will go in the draw win one $100 Amazon gift voucher. Throughout the study the Smiling Mind team will monitor using participant email addresses provided at baseline whether intervention participants have downloaded the application and are participating. If after 5 days participants have not downloaded the app and started engaging in the program, then the University of
Newcastle team will send an email reminder. The email address will also be used to match participant responses between surveys. The data collected from interventions application usage will also be analysed to determine patterns of usage and engagement.
It is hypothesised that participants who engage in the Smiling Mind program will have significantly improved well-being in comparison to the control group.
