Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The interactive intervention will be delivered during one online session lasting between 20 and 25 minutes. The intervention will address 3 different constructs, (1) designed to encourage supportive sun protection related attitudes and beliefs, (2) fostering perceptions of friendship group normative support for sun protection and (3) increase perceptions of control/self-efficacy over using sun protection. A series of questions/ quizzes will be used to encourage supportive sun protection related attitudes and beliefs. Animated scenarios depicting situations in which one character is faced with opposition from an important referent to performing sun protective behaviour will be used to foster perceptions of friendship group normative support for sun protection. A series of questions will be used to prompt participants to consider how they would respond and how they may prevent the situation from occurring. An increase in perception of control/self-efficacy over using sun protection will be the aim of a set of animated scenarios and questions which ask participants to consider scenario specific barriers to sun protective behaviour and to suggest solutions to the barriers. Increasing intention to sun protect will be addressed through setting sun safe goals and through the creation of a contract outlining intention.

Behaviour
Comparator / control treatment
Participants will be randomly allocated to the intervention group (n = 200), the information only group (n = 200) or the control group (n=20). The information only group will be asked to view an 8 minute online DVD and three fact sheets relating to sun-protective behaviour which are currently available from Cancer Council Queensland’s website.

The control group will not be asked to do anything beyond completing the 3 questionnaires.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants from a previous research study relating to sun protection who have already provided their consent to be contacted for participation in further research studies, will receive an email invitation to participate in the main research study.

Additionally, Australian adults (approximately equal numbers of males and females) living in metropolitan, regional and coastal areas will be approached via QUT media releases, through use of recruitment notices in newsletters and newspapers, radio stations, and community billboards, through QUT classifieds and websites and email lists and through snow balling techniques.
Participants will be provided with information via email on a participant recruitment flyer. They will be provided with an online link to the participant information sheet and will provide their consent to participate by ticking a box indicating they agree to participate. Participants will be randomly allocated to their treatment group via a computer generated number sequence after completion of the first questionnaire.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Consenting participants who have completed the first questionnaire will be randomised in a 200:200:20 ratio to the intervention or information only or control group using a computer-generated random number sequence.
