Protocolo para el Desarrollo y Prueba de la Efectividad de un Programa Educativo de Autodetección del Cáncer de Piel: Un Ensayo Controlado Aleatorizado

23 de septiembre de 2026 actualizado por: National University Hospital, Singapore

Protocolo para el Desarrollo y Prueba de la Eficacia de un Programa Educativo de Autodetección del Cáncer de Piel: Un Ensayo Controlado Aleatorizado

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.

Descripción general del estudio

Descripción detallada

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.

Armas e Intervenciones

Grupo de participantes/brazo
Intervención / Tratamiento
Comparador de placebos: 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.

Experimental: 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.

Experimental: 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.

This 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.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Change in competency scores
Periodo de tiempo: 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
Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Knowledge of skin cancer, sun protection and skin self-examination
Periodo de tiempo: 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.

Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
Attitudes toward carrying out sun protection behaviours
Periodo de tiempo: 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

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
Periodo de tiempo: 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

Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
Behavioural outcomes (sun protection behaviour and skin self-examination)
Periodo de tiempo: 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.

Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
Intentions of participants toward carrying out skin cancer risk prevention strategies
Periodo de tiempo: 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.

Baseline, immediately post-intervention (for intervention arms), 4 months post-intervention
