Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first, therefore international submissions should allow additional time for registration or updates to registration records. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will have 6 month access to a web site which allows them to generate text for their own messages. Participants will also determine when the messages will be sent to their mobile phone. The frequency of use of the web site and messaging is at the participants own discretion. They are the most qualified to determine when they will need a prompt to consider their safety and drinking behaviour. The control group will have 3 months access to the web site messaging. This is a feasibility study. The researchers do not wish to lead the participants regarding message content or frequency. The web site will provide instructions on how to use the messaging but no suggestions for message content. At the end of three months, both the intervention and control groups will have access to the intervention. This is to assess longevity of use and engagement with the web site.

Comparator / control treatment
Control treatment is 3 months access to a web site which has a community chat page and instructions on how to use the pending messaging option. This is the same web site that the intervention group will access but the message function will be hidden from the Control group. At the end of 3 months the control group will be given access to the message component.

Summary
Brief summary
SPILL IT is a small study which aims to assess whether young drinkers (aged 18-34) would use a web site which helps them to get reminders on their mobile phones to keep safe while drinking. To ensure the safety messages are relevant, the young drinkers will write their own message and set the date and time when the message is sent to their phone. The reason for this is that plans to keep safe during drinking are forgotten when they have had a few drinks and are interacting with friends. A text message to their phone, while they are drinking, may remind them of their plans and therefore stop them getting hurt.
