简要总结
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.
详细描述
Reducing skin cancer related morbidity and mortality involves two broad domains; (1) Identification and early detection of skin cancers and (2) Awareness and behavioral change to reduce modifiable risk factors like UV exposure. Regular self-examination and public education have been shown in RCTs to improve knowledge and identification of skin cancers. However most of these existing studies and the tools they utilise rely on Western-centric photographs and messaging, such as the 'ABCDE rule' for superficial spreading and nodular melanoma. These neglect skin cancers far more common in skin of colour population such as acral lentiginous melanomas, pigmented basal cell and squamous cell carcinomas.
In addition to improving detection, effective behavioural change strategies are needed to encourage protective practices such as regular sunscreen use. Message framing has gained interest as a behavioral change technique: gain-framed messages emphasize the benefits of adopting a behavior, while loss-framed messages highlight the negative consequences of not doing so. Although message framing is widely used in health communication, evidence of its effectiveness in promoting skin cancer-related behaviors is unclear.
Effectiveness of our proposed intervention can help to increase adoption of sun protective behaviours, improve detection rates of skin cancer and allow earlier medical intervention, hence reducing morbidity and mortality of skin cancer.

研究组 & 干预措施
Control
Participants will fill up a baseline competency examination and questionnaire, and another at the 4 month mark. Access to the intervention for control group participants will only be provided after the 4-month questionnaire is completed.
干预措施: Wait-list Control (Behavioral)
Intervention with gain framing
Participants will fill up a baseline competency examination and questionnaire. Afterwards, they will have access to a website with gain-framed messages emphasising benefits of adopting a behaviour. Thereafter, another competency questionnaire will be administered following completion of material.
干预措施: Skin Cancer Self-Detection Educational Program with gain-framing (Behavioral)
Intervention with loss framing
Participants will fill up a baseline competency examination and questionnaire. Afterwards, they will have access to a website with loss-framed messages highlighting consequences of failing to adopt a behaviour. Thereafter, another competency questionnaire will be administered following completion of material.
干预措施: Skin Cancer Self-Detection Educational Program with loss-framing (Behavioral)
结局指标
主要结局
Change in competency scores
时间窗: Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
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
次要结局
- Knowledge of skin cancer, sun protection and skin self-examination(Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention)
- Attitudes toward carrying out sun protection behaviours(Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention)
- Subjective norms, which refer to participants' perception of whether significant individuals in their lives would support sun protection behaviours(Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention)
- Behavioural outcomes (sun protection behaviour and skin self-examination)(Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention)
- Intentions of participants toward carrying out skin cancer risk prevention strategies(Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention)
