Plain English Summary
Background and study aims
Getting sunburnt is the biggest risk factor for melanoma (the worst type of skin cancer), but using sunscreen can help adolescents protect themselves from the harmful effects of the sun. Skin self-examination can help people detect melanoma and early detection improves the chances of not dying from the disease. Talking about skin cancer with family and friends can help adolescents seek professional help and advice promptly if they are worried about changes to their skin. The aim of this study is to evaluate an intervention called ‘Do you know your skin? aimed to increase sunscreen use, skin self-examination and talking about skin cancer.
Who can participate?
Male and female secondary school attenders aged 15-16
What does the study involve?
Participating schools are randomly allocated to the intervention group or the control group. In the intervention group schools the intervention is delivered by a skin cancer specialist nurse. The nurse meets with classes of adolescents for one hour during a school lesson. The lesson includes a short film (‘Dear 16 year old me’), factual information about melanoma prevention and early detection, and a short quiz to determine skin type. Sunscreen use and skin self-examination handouts are given to encourage adolescents to plan for using sunscreen and to practice skin self-examination at home. A young adult who was treated for melanoma in the past accompanies the nurse to talk about his experiences of being diagnosed with melanoma. He emphasises the importance of using sunscreen and of skin self-examination. Sunscreen use, skin self-examination and talking about skin cancer are assessed using a survey at 2 weeks before the intervention and 4 weeks after the intervention has been delivered. The schools allocated to the control group receive the same intervention after the study has ended.
What are the possible benefits and risks of participating?
The benefits are that students will learn about melanoma from an expert and be able to examine their skin for signs that might be linked to melanoma. For any student who has personally been affected by cancer the study may make bring up some emotion around this issue, and staff will be on hand to deal with anything that arises of this nature.

Promoting sunscreen use and skin self-examination to improve early detection and prevent skin cancer: quasi-experimental trial of an adolescent psycho-educational intervention
This feasibility trial, in preparation for a future effectiveness trial, is to test an intervention to increase sunscreen use, and skin self-examination behavior during adolescence.

The feasibility study used a quasi-experimental design, with schools allocated by the research team to an intervention group or control group, to find out if the intervention worked as intended and to examine trial procedures.
The intervention "Do you know your skin" was developed by the research team with the support of an expert working group that included two people who had been treated for skin cancer, three experts in health behaviour change, one policy-maker in cancer early detection, one skin cancer specialist nurse and one dermatologist. The intervention has two parts: a presentation delivered to students in school and a home-based assignment.
A practicing skin cancer nurse specialist delivers a 50-minute presentation to students about skin cancer and skin self-examination (SSE). Each presentation is delivered by the nurse on one occasion during the school day in a classroom. The nurse will deliver the presentation with the aid of Microsoft PowerPoint slides and cover: personal experiences of skin cancer, incidence patterns, risk factors, associations between disease staging and survival, and benefits of SSE. A young adult skin cancer survivor will give a brief 5-minute talk after the nurse-delivered presentation. The talk is about his personal experience of melanoma diagnosis at 16 years old, impacts on his life and his views on sunscreen use and SSE behaviour.
A home-based assignment will compromise a booklet with instructions. Adolescents will be given an exercise to self-examine their skin and be asked to complete an action plan for regular sunscreen use and an action plan for SSE. The SSE component of the booklet has three sections: a) information on the importance of planning; b) instructions of what should be included in the plan; c) formulating ‘if-then’ action plans (e.g., If I am having a shower then I will check my skin) and coping plans (e.g. To make sure I don’t forget, I will add the appointment to my calendar and put a reminder post-it on the fridge).
The school allocated to the control group will receive the same intervention after the study has ended.
Primary outcome measures
All outcomes measured using self-completed survey on pen and paper, administered as a group activity within the allocated schools at 2 weeks before the intervention (baseline), and 4 weeks after the intervention has been delivered:
1. Sunscreen use intention, measured using one item: ‘Do you intend to use a high factor sunscreen if you are going out in the sun?’ A five-point Likert scale was used to gauge response from 1 (definitely will not) to 5 (definitely will)
2. Sunscreen use planning, measured using five items: ‘I have made a detailed plan on… i) What sunscreen I will use; ii) When I will use it; iii) Where I will get it from; iv) How I will remember to carry it’; and, iv) What to do it I am tempted not to use it.’ A five-point Likert scale was used to gauge response from 1 (completely disagree) to 5 (completely agree)
3. Skin self-examination (SSE) behaviour, measured using one item: ‘In the past month, have you examined your skin for signs of possible skin cancer?’ Responses were yes, no or don’t know. SSE intention was measured using one item: ‘Do you intend to examine your skin for signs of possible skin cancer on a regular basis.’ A five-point Likert scale was used to gauge response from 1 (definitely will not) to 5 (definitely will)
4. SSE planning, measured using four items: ‘I have made a detailed plan regarding…
4.1. When to examine my skin for signs of possible skin cancer
4.2. Where to examine my skin for signs of possible skin cancer
4.3. How to examine my skin for signs of possible skin cancer’
4.4. ‘I have made a plan for dealing with things that could stop me from examining my skin for signs of possible skin cancer’
A five-point Likert scale was used to gauge response from 1 (completely disagree) to 5 (completely agree)
5. Talking about skin cancer, measured using one item: ‘Have you spoken to anyone about skin cancer in the last month?’ Responses were yes or no
6. Illness perceptions: Five dimensions of the CSM were measured using the following items:
6.1. Identity: ‘How much would getting skin cancer affect your life?’ An 11-point Likert scale was used to gauge response from 0 (not at all) to 10 (it would severely affect my life)
6.2. Control: ‘How much control do you feel you have to prevent yourself from getting skin cancer?' An 11-point Likert scale was used to gauge response from 0 (not at all relevant) to 10 (very relevant)
6.3. Timeline: ‘Given your age, how relevant is it to regularly examine your skin for signs of possible skin cancer?’ An 11-point Likert scale was used to gauge response from 0 (not at all relevant) to 10 (very relevant)
6.4. Consequence: ‘How painful do you think the effects of treatments for skin cancer would be?' An 11-point Likert scale was used to gauge response from 0 (not at all painful) to 10 (extremely painful)
6.5. The following open-ended question was used to measure the CSM dimension cause: ‘Please list in rank-order the three most important factors that you believe cause skin cancer'
Secondary outcome measures
1. Intervention adherence and acceptability. Intervention adherence was defined in two ways: proportion of eligible adolescents on a school register receiving the presentation, and number of participating adolescents completing the home-based assignment. The number of adolescents in intervention schools who received the presentation was objectively measured using school attendance records. The number of adolescents doing the home-based assignment was self-reported at follow-up.
2. Adolescents’ opinions about relevance, content, format and delivery methods, explored in focus groups conducted in intervention group schools. Focus groups (n=3; 1 intervention group school was unavailable due to exam revision timetabling) to elicit adolescents’ views on the intervention’s relevance, content, format and delivery methods were conducted approximately 8 weeks after the intervention. Focus groups were audio-recorded and took place during school time, in a classroom, at a time and place selected by the teacher and lasted approximately 50 minutes. Confidentiality was explained and informed consent was obtained in writing.
