Interventional
Description of intervention(s) / exposure
The current study aims to conduct a randomised controlled trial over 3 months that investigates the effectiveness of an internet-delivered alcohol intervention. The intervention consists of an interactive, internet based, self-help program comprising 5 modules, each covering a specific theme (e.g. mindfulness, cognitive restructuring). Each module was designed to take between 30 and 60 minutes to complete (i.e. approximately 5 hours in total). Participants are able to skip certain sections and can complete modules in any order. The study also aims to enhance retention rates to the online program with the addition of reminder text messages to motivate clients to continue logging on to the program. Text messages will be sent on average 3-4 times per week over the three month trial period.
Thus, the intervention condition involves open access to an online alcohol intervention and the addition of reminder text messages.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will visit www.ontrack.org.au in response to referral or advertising and are led to a registration page where they are provided with information about the research and are asked to consent to participating in the study. They are also required to register to receive a screening call.
During the call a screening information sheet is read over the phone and the participant is asked for verbal consent for screening. If the participant meets screening eligibility criteria, they are invited to complete a baseline assessment. Participants are emailed a link that takes them to the online assessment questions. After they have completed all baseline assessments, they are randomly allocated to one of the two treatments and are provided with a username and password to log in to the program. Participants then complete the program at their own pace.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization will occur via a true random number service and carried out by an independent researcher.
