皮膚がん自己検出教育プログラムの開発と効果検証のプロトコル：無作為化比較試験
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.
調査の概要
状態
詳細な説明
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.

参加者グループ / アーム |
介入・治療 |
|---|---|
|
プラセボコンパレーター：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. |
Participants in the control group will gain access to the intervention websites after the 4-month questionnaire is completed. |
|
実験的：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. |
This 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. |

Afterwards, they will have access to a website with loss-framed messages highlighting consequences of failing to adopt a behaviour.

Knowledge of skin cancer, sun protection and skin self-examination
時間枠：Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
|
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. |

Attitudes toward carrying out sun protection behaviours
時間枠：Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
|
6 questions graded on a 7-point Likert scale, with higher scores indicating better attitudes toward sun protection behaviours |

Subjective norms, which refer to participants' perception of whether significant individuals in their lives would support sun protection behaviours
時間枠：Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
|
7 questions graded on a 7-point Likert scale, with higher scores indicating a greater influence of others' perception on their sun protection behaviours |

Behavioural outcomes (sun protection behaviour and skin self-examination)
時間枠：Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
|
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. |

Intentions of participants toward carrying out skin cancer risk prevention strategies
時間枠：Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
|
Sun Exposure and Protection Index (6 questions with an additional adapted question). Each given response score (0-4) are summed, with scores ranging from 0-24, with higher score indicating a low propensity to increase sun protection. 2 additional questions regarding participants' intentions of conducting a skin-self examination. 7 point Likert Scale (1-7), with higher score indicating higher intentions of conducting a skin-self examination. |
