About this trial
Skin cancer is a significant public health concern, even in an Asian society like Singapore where it ranks among the top 10 cancers. This RCT tests the effectiveness of a skin cancer educational intervention to improve skin cancer outcomes among skin-of-color individuals, including the effects of gain versus loss framing.

Treatments tested in this trial
Skin Cancer Self-Detection Educational Program with gain-framing
BehavioralThis educational website will feature gain-framing messages, emphasizing the benefits of adopting a behavior, utilising positive language and analogies. The interventional domains are (1) Education on skin cancer risk factors and epidemiology, (2) UV Protection Advice, (3) Skin Self-Examination Techniques and (4) Differentiating benign vs malignant skin conditions.
Skin Cancer Self-Detection Educational Program with loss-framing
BehavioralThis educational website will feature loss-framing messages, highlight the consequences of failing to adopt a behavior, utilising negative language and analogies. The interventional domains are (1) Education on skin cancer risk factors and epidemiology, (2) UV Protection Advice, (3) Skin Self-Examination Techniques and (4) Differentiating benign vs malignant skin conditions.
Wait-list Control
BehavioralParticipants in the control group will gain access to the intervention websites after the 4-month questionnaire is completed.

Trial outcomes
Primary outcomes
1
Change in competency scores
Scores measured as percentage of correct questions answered. Range from 0% to 100% with higher score indicating higher ability to differentiate benign from malignant skin lesions. Change in scores will be calculated and compared between 1. Both intervention arms with the control group at 4 months, and 2. Between gain framed and loss framed intervention arms at 4 months
Time frame
Baseline, immediately post-intervention (for intervention arms), 4 months post-interventionSecondary outcomes
1
Knowledge of skin cancer, sun protection and skin self-examination
20 Multiple Choice Questions created based on intervention website. Score range from 0 to 20, with a higher score indicate higher knowledge in risks of skin cancer, appropriate sunscreen use and features of cancerous lesions.
Time frame
Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention2
Attitudes toward carrying out sun protection behaviours
6 questions graded on a 7-point Likert scale, with higher scores indicating better attitudes toward sun protection behaviours
Time frame
Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention3
Subjective norms, which refer to participants' perception of whether significant individuals in their lives would support sun protection behaviours
7 questions graded on a 7-point Likert scale, with higher scores indicating a greater influence of others' perception on their sun protection behaviours
Time frame
Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention4
Behavioural outcomes (sun protection behaviour and skin self-examination)
Sun Exposure and Protection Index. 9 questions graded on a 5-point Likert scale assessing sun habits and sun protection behaviour. Lower scores indicate more optimal sun protection behaviours, with an additional adapted question. 11 additional questions regarding participants' sunscreen usage (e.g. type of sunscreen, frequency of reapplication), and skin-self examination, with a lower score indicating more optimal sun protection behaviours.
