Skin Lesion Awareness Personal Application (SLAPA) - Investigating the impact of smartphone app on skin cancer knowledge and prevention behaviour in adults

We will provide a randomized half of our cohort with the Skin Lesion Awareness Personal Application (SLAPA) mobile phone application. This application has been designed by the Plastic Surgical Department at Dunedin Hospital to help people learn about common skin lesions, teach them how to perform skin checks and prevent skin cancer. The app's information will be delivered through infographics, text and the use of clinical photos to demonstrate lesions. The sections of the app are common skin lesions (covering melanoma, BCC, SCC, seborrheic keratosis, actinic keratosis, atypical naevus), prevention, self skin check, melanoma risk calculator, location-specific UV index, and how to seek help for skin lesions. The app also provides push notifications to a device that state the UV index and remind the user to protect themselves. Participants in the SLAPA arm of the study will be given instruction on how to download and register for the app on their personal smartphones or tablet. They will be asked to read the content of the app at least once during the study which will take approximately 30 minutes to review in its entirety and leave the SLAPA app on their phone for the duration of the study (3 months). Adherence/use of the intervention will be monitored through participants' self-reported questionnaires, which include questions about how often participants use the app in a week, approximate minutes of use a day and what their baseline familiarity with a smartphone is like. No app analytics will be used for the purpose of this study.
