Objective: Strategic storytelling can be used to reframe dominant cultural narratives and improve community health outcomes. This pilot study assessed the impact of an original, online 3-week e-course, delivered from November to December 2021, in increasing learners' knowledge of and concern for the seriousness of skin-shade discrimination and the use of skin-lightening products in India, increasing learners' understanding of storytelling-based communication techniques for public health promotion, and increasing learners' intentions to use strategic storytelling for social change. Design, Setting and Method: The course used case-method pedagogy to address colourism and cosmetic skin lightening. Learners (N = 25) completed a pre-course baseline survey on their knowledge and concerns regarding colourism and the use of skin-lightening products, as well as their expectations and interests in taking the course. Following course completion, learners completed a post-webinar survey. The Wilcoxon Signed-Rank test was used to assess differences from pre- to post-course surveys on quantitative items. Open-ended responses were also analysed using qualitative content analysis for recurring themes on learner interest and experience. Results: From pre- to post-course surveys, there were significant improvements in learners' knowledge of skin shade discrimination and the use of skin-lightening products (p < 0.05). Learners indicated being more concerned about the seriousness of skin shade discrimination post-course compared to pre-course. Learners also described a positive learning experience and indicated that the e-course enhanced their understanding of strategic storytelling. Conclusion: Findings highlight the importance of an original e-course that uses case-method pedagogy to build knowledge and skills that addresses the impacts of colourism on the health of Indian adolescents and provides new directions for future research on health education interventions that aim to tackle colourism.
