Brief summary

The aim of this study is to evaluate the impact of a personalised skin cancer prevention strategy on UV exposure in adults with a history of skin cancer. Who is it for? You may be eligible for this study if you are aged 18 years and over, and have previously been diagnosed with skin cancer (including melanoma, basal cell carcinoma, squamous cell carcinoma). Study details Participants will be randomly assigned to either an intervention or control group. The intervention comprises 10-days wear of a Sun Watch, which displays the real-time UV Index and the wearer’s daily cumulative UV exposure alongside receiving personalised SMS sun protection reminders, and educational information on skin cancer prevention, early detection and treatment. The control arm will receive the educational information only. Participants will be asked to complete questionnaires on their sun protection behaviours, physical activity, psychosocial outcomes and their perspective on the intervention. It is hoped that findings from this study will help researchers understand the effect of a personalised skin cancer prevention strategy on primary prevention behaviours.

Interventions

Participation in the study for intervention participants will involve: 1. The completion of an online survey at baseline. This survey will seek information on demographics, skin cancer risk factors, sun habits, sun protection behaviours and psychological outcomes. This survey should take around 20 minutes to complete. 2. 10-day wear of a UV dosimeter during the intervention period. 3. Completing a 10-day activity diary during the intervention period. This survey should take around 5 minutes to

Participation in the study for intervention participants will involve: 1. The completion of an online survey at baseline. This survey will seek information on demographics, skin cancer risk factors, sun habits, sun protection behaviours and psychological outcomes. This survey should take around 20 minutes to complete. 2. 10-day wear of a UV dosimeter during the intervention period. 3. Completing a 10-day activity diary during the intervention period. This survey should take around 5 minutes to complete. 4. Receiving one educational booklet: Melanoma Prevention and Early Detection Guide (Melanoma Institute Australia). 5. The Sun Wise Strategy, comprising of 10-day wear of the Sun Watch and daily SMS sun protection reminders. The Sun Watch is a UV dosimeter (electronic measure of real-time sun exposure, measured in standard erythemal doses, SEDs) which displays the real-time UV index and the wearer’s cumulative UV exposure. Adherence to the intervention will be assessed when the watches are returned to the study team. As the UV data are downloaded, a member of the research team will check the data and identify any potential issues, such as non-compliance (i.e. Sun Watches being left out in the sun or indoors unworn) or any malfunctions.
