Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The aim of this current study is to establish whether a web-based cognitive behaviour therapy (CBT) intervention is effective in treating amphetamine use and its associated harms. Participants will be asked to complete one 30-minute session per week for five weeks. Sessions include components such as motivational interviewing, goal setting, thought monitoring, cognitive restructuring, pleasant activity scheduling, and relapse prevention. Adherence will be monitored via the website, which will provide information about when sessions were accessed and which pages were viewed.

Of particular interest is the potential role that contingency management may have on treatment success. Another aim of this research is to identify predictors of treatment outcome for amphetamine users (self-efficacy and impulsivity).
