Description of intervention(s) / exposure
The S-Check App has been developed as a self-administered smartphone based harm reduction and early intervention application for those who use methamphetamine. The S-Check App will be provide the user with information to manage their methamphetamine use and support services available, should they need to seek help. One group will be randomize to have immediate access to the App for 28 days while the one group will be randomize to have delayed access to the App 28 days later. Both groups will be asked to complete a surveys at the start and 28 days to assess whether there has been any behavioral change in their methamphetamine use.
Frequency and use of the features of the App will be at the discretion of the participant for the 28 days that they will have access to the App. The App has several sections, such as physical health, social health and psychological well being. The participant will be able to enter information into these sections and the App will be able to provide advice based on the associated risk of the information supplied. The App also has a diary section, where the participant can write and upload videos, audio and pictures to seek track of their progression. They will be awarded achievement badges upon completion of each section of the App. Internal metrics will capture which sections of the App are used, the frequency and the duration of App use. This information together with the surveys will assist the study team in determining the efficacy and feasibility of the App as a harm reduction and early intervention tool.

Outcomes
Primary outcome [1] 319592 0
To see whether the S-Check App can motivate behavioural change amongst people who use methamphetamine. Participants in both arms will be asked to complete the Readiness to Change, General Help-Seeking and Actual Help Seeking Surveys. Those who have immediate access to the App will complete the surveys at the start of the trial and 28 days following usage of the App. Those who have been randomised to having delayed access will complete the survey at the start of the trial and then again at 28 days before having access. The data from both groups will be reviewed to assess whether the App motivated change in behaviour.

Efficacy
Statistical methods / analysis
510 participants will be recruited in the delayed access group and 510 participants in the immediate access group. Overall, 1020 participants will be recruited altogether. The study is designed to detect a medium effect size (e.g. d=0.5, 20) with a power of 0.8 and alpha set at 0.05. To allow for attrition, 1020 participants will be recruited, with an estimated drop-out rate of 50% at Day 28.

Summary
Brief summary
The main purpose of this trial is to see whether the S-Check App can motivate behavioural change in those who use methamphetamine. The S-Check App has been developed as a harm reduction and early intervention tool It provides information on methamphetamine use and provides information on support services. One group will be randomised to have immediate access to the App for 28 days. The other group will have have access to the App after 28 days (delayed access). Both group at baseline (Day 0) will be asked to complete the Readiness to Change, General Help-Seeking and Actual Help-Seeking questionnaires. Those given immediate access to the App will repeat the survey at 28 days. Those given delayed access will repeat the survey before access is given. Both groups will also be asked to participate in a telephone interview to capture their experience using the App. App usage metrics will also be collected. The information collected will assist to further develop the App as a self-administered tool for those who use methamphetamine but do not wish seek traditional modes of treatment.
