Brief Summary

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.

Conditions

Skin Cancer Prevention; Skin Cancer; Benign Skin Growth

Keywords

skin cancer; skin cancer education; skin cancer intervention; patient education; digital education

Outcome Measures

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

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

Secondary Outcomes (5)

• 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

Study Arms (3)

Control

PLACEBO COMPARATOR

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.

Behavioral: Wait-list Control

Intervention with gain framing

EXPERIMENTAL

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.

Behavioral: Skin Cancer Self-Detection Educational Program with gain-framing

Intervention with loss framing

EXPERIMENTAL

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.

Interventions

Wait-list Control BEHAVIORAL

Participants in the control group will gain access to the intervention websites after the 4-month questionnaire is completed.

Control

Skin Cancer Self-Detection Educational Program with gain-framing BEHAVIORAL

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.

Intervention with gain framing

Skin Cancer Self-Detection Educational Program with loss-framing BEHAVIORAL

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.
