Description of intervention(s) / exposure
This study investigated the impact of the melanoma awareness video ‘Dear 16-year-old me’, a self-assessment of perceived melanoma risk, and a control condition.

'Dear 16-year-old me" is a five minute melanoma awareness video developed by the David Cornfield Melanoma Fund in 2011, which is available online. The video addresses the importance of protecting and checking one’s skin via personal testimonies from real life melanoma survivors and their families, who share with their younger selves the advice that could have prevented them or a loved one from developing melanoma.

The risk self-assessment used in this study was one component of a self-administered melanoma questionnaire that assesses personal risk, level of concern, protective behaviour, and knowledge (Gillespie et al., 2011). For the purpose of this study, only the risk component of the questionnaire was used (the Personal Risk for Melanoma Questionnaire; PRMQ). This 7-item self-assessment collects information about skin type, hair colour, and other personal factors that can contribute to an individual’s likelihood of developing melanoma. Each response attracts a score, and the sum of these is a numerical indication of melanoma risk, ranging on a scale from -2 to 22.

Outcomes
Primary outcome [1] 300715 0
Intended sun protection behaviours were measured using the Sun Protection Behaviours Scale (Weinstock et al., 2000), with two items modified to include SPF 30+ specifications, Participants rated how often they intended to engage in 10 sun protection behaviors (e.g., “Wear a hat”) when out in the sun next summer on a 5-point scale ranging from 1 = never to 5 = always.
Timepoint [1] 300715 0
Follow-up (2 weeks)
Primary outcome [2] 300716 0
Skin cancer fear was measured using 8 items adapted from the Breast Cancer Fear Scale (Champion et al., 2004), which assesses the extent of cancer-specific fear. Participants rated their agreement with statements regarding their beliefs about skin cancer skin cancer (e.g., “The thought of skin cancer scares me”) on a 5-point scale ranging from 1 = strongly disagree to 5 = strongly agree.
Timepoint [2] 300716 0
Follow-up (2 weeks)
Primary outcome [3] 300717 0
Perceived threat of skin cancer was assessed using three perceived severity items and three perceived susceptibility items from the Risk Behavior Diagnosis Scale (Witte, 1996). Responses were averaged to create an overall index. Participants rated their agreement with statements about the severity of skin cancer (e.g., “I believe skin cancer is severe”) and their susceptibility (e.g., “I am likely to contract skin cancer”) on a scale ranging from 1 = strongly disagree to 5 = strongly agree.

Efficacy
Statistical methods / analysis
A series of 3 (Group: "Dear 16 year-old-me", PRMQ, control) × 3 (Time: baseline, post-intervention, follow-up) between-within subjects analyses of variance (ANOVA) were conducted to determine the impact of the intervention materials on perceived threat, fear, and intended sun protection scores. A Bonferroni adjusted alpha level of .017 was employed to account for multiple comparisons. Post hoc analyses using the LSD post hoc criterion for significance were used to determine differences between groups.
Power analysis was conducted prior to the study in order to estimate the required sample size. To attain a desired power of .80 or above for a corrected alpha level of .017 and a small effect size (ES = .3), a total sample of n=147 was necessary. On the basis of 50 respondents per condition, the current sample of n=222 at baseline and n=187 at follow-up was adequate to conduct analyses of variance with effects of small size.
