Study type
Description of intervention(s) / exposure
Use of a web based, text messaged delivered BI to affect change in harmful drinking behaviour. Drinking behaviours and harms will be assessed by the validated Alcohol Use Disorders Identification Test (AUDIT) alcohol screening test as well as the brief version of the Young Adults Alcohol Related Consequences Questionnaire (B-YAARCQ) to assess and reduce alcohol-related harm. These will be administered on sign up, at 6 weeks and at 3 months following recruitment.
There are three arms to study:
The first arm gives access to the website questionnaires only ("Control arm").
The second arm delivered standardized text messages as a BI at pre-determined times ("Passive arm") weekly for six weeks.
The third arm delivered text messages designed by the participants ("Active arm") weekly for six weeks.
Participants will be approached (face-to-face) to enroll once admitted to the Plastic Surgery department at Middlemore hospital with an alcohol-related injury requiring treatment. Approach will be made by a non-surgical team member. Patients will be given a written information sheet about the trial. All other information in provided on line, via the customised SpillIt website. Randomisation will happen automatically by the website computerised randomization process once the patient signs up. A copy of the standardized text messages delivered to group two is attached as a separate document at the end of this application (called "my message schedule"). Participants in the third (active) arm will then have the opportunity to write their own personalised messages and determine the dates and times they will be delivered via text message to their phones. These participants are then given free reign ton type their own message (any wording, in any language) into a field on the website; select the date and time from the integrated calendar, and submit the message. This will then be delivered to the mobile phone umber linked with the account at the pre-determined time. No specific guidance is given to these participants regarding their messages. They are able to text anything they like to themselves. The participants are left alone to type this, to allow privacy of message content from the recruiter. Previous research has shown approximately 5% of messages to be "anti-messages" - that is, not related to safe alcohol practices, or even supporting higher alcohol consumption. The researchers consider this to be an acceptable trade-off for allowing free reign, personalised safe use of alcohol related messages in the remaining 95%.

Comparator / control treatment
Control group is arm one. These are patients with alcohol related injuries who will not receive the text message BI but will undertake the AUDIT and (B-YAARCQ) assessments at the same timepoints as arm 2 and arm3 participants.

Statistical methods / analysis
Quantitative outcome measure is change in scores / values from baseline to post-BI. Paired t-testing, one-way ANOVA and repeated measures ANOVA are likely to be used for analysis, depending on the number of measures and variables obtained.

Brief summary
This research utilizes an established website as well as the validated Alcohol Use Disorders Identification Test (AUDIT) alcohol screening test as well as the brief version of the Young Adults Alcohol Related Consequences Questionnaire (B-YAARCQ) to assess and reduce alcohol-related harm. Patients admitted under plastic surgery with personal injury and a history of alcohol intake will be approached for enrolment. They will be directed to the SpillIt website to complete the AUDIT and B-YAARCQ online and consent to take part in the study. From there, they will be randomised to either no text message intervention (control arm), access pre-written (passive arm) or to self-design (active arm) alcohol intervention text messages. If they are randomised to an intervention arm, the messages will be timed to be delivered to their phone when they were most likely to be consuming alcohol, with the aim of encouraging contemplation of their drinking and staying safe. Patients will be followed up at six weeks, then three months and longer if feasible. AUDIT and B-YAARCQ will be re-administered in person or the shortened version (AUDIT-C) may be administered via text messaging. Participant feedback will also be solicited. This research doesn’t demonise alcohol but instead encourages consideration of the unwanted consequences which may result from risky drinking.
