Description of intervention(s) / exposure
The S-Check 2.0 smartphone app is based on the service model of the St Vincent's Hospital Sydney Stimulant Treatment Program. The app i) engages methamphetamine users who are not seeking traditional modes of treatment, and ii) develops app users’ knowledge of methamphetamine and the risks and harms associated with methamphetamine use. S-Check 2.0 content includes (1) initial self-assessment (i.e. self-reported responses to a series of brief validated measures) of social health and lifestyle, physical health, sexual health and psychological wellbeing, (2) feedback on self-assessment results (i.e. tailored feedback text summarising results), along with links to readily available support resources and information on methamphetamine, (3) daily tracking functionality for app users to track their methamphetamine use and its associated risks over time. Participants are able to access S-Check 2.0 as frequently as they wish over the course of the study; usage data (e.g. log-in data) will be collected to assess adherence. S-Check 2.0 will be available for 24 months in total (October 2024 to October 2026); participants will be recruited over the course of this 24-month period, with recruitment closing one month prior (i.e. September 2026) to S-Check 2.0 becoming unavailable to allow one month of data collection for the final participants.

Summary
Brief summary
This study aims to characterise the demographic and methamphetamine use profile of individuals downloading the S-Check 2.0 app, and examine associations between participant characteristics, app usage, and outcomes. Study results will inform future research and hybrid treatment options by improving understanding the characteristics of individuals that use a smartphone app as a resource for their methamphetamine use, and providing insights on how app usage is associated with changes in methamphetamine use and professional help-seeking.
