Thesis Abstract
The increasing prevalence of melanoma and the often late-stage diagnosis underscore the critical need for enhanced early detection skills among the general population and healthcare professionals. Despite the availability of clinical guidelines, many individuals lack the necessary knowledge to identify early signs of melanoma, resulting in delayed diagnoses and poorer prognoses. This study aims to develop a user-centered mobile application that facilitates early melanoma detection skills and to evaluate its effectiveness in improving users' diagnostic accuracy and confidence. The research adopts a mixed-methods, quasi-experimental design, integrating both quantitative and qualitative data to provide a comprehensive assessment of the app’s impact. The target population comprises adults aged 18-45 from urban healthcare settings, with a sample size of 200 participants, randomly assigned to either an intervention group using the app or a control group receiving traditional educational materials. Data collection instruments include a validated melanoma knowledge questionnaire, a skill assessment checklist, and semi-structured interview guides for qualitative feedback. The quantitative data will be analyzed using descriptive statistics, paired t-tests, and multiple regression analyses to assess changes in knowledge and detection skills pre- and post-intervention, while thematic analysis will be employed for qualitative interviews. The app’s usability and user experience will also be evaluated through the System Usability Scale (SUS). It is anticipated that the mobile app will significantly enhance participants’ melanoma recognition abilities, increasing diagnostic accuracy by at least 30% compared to baseline and traditional methods, with improvements observed in both knowledge retention and confidence levels. The findings are expected to demonstrate that interactive, app-based training facilitates more effective learning of melanoma recognition criteria, aligning with the Social Cognitive Theory of self-efficacy and Cognitive Load Theory principles, which support interactive and self-guided learning modalities. By providing empirical evidence for the efficacy of mobile health interventions in dermatology, this study contributes valuable insights into the integration of digital tools for preventive health education and early cancer detection strategies, particularly targeting populations with limited access to dermatological services. It will also highlight best practices for designing engaging, accessible mobile applications that can be adapted to other skin conditions and health screening programs. The primary conclusion indicates that the mobile app effectively improves melanoma detection skills and may serve as a scalable supplement to clinical training programs. Recommendations include further validation studies with larger, diverse populations, integration of the app into routine dermatology and primary care workflows, and exploration of longitudinal impacts on health outcomes. Overall, this research advances the understanding of digital health innovations in dermatology and emphasizes the potential for technology-driven educational interventions to catalyze early diagnosis and improve patient prognosis in melanoma management.
Thesis Overview
This research aims to develop a mobile application that helps users recognize early signs of melanoma, a dangerous type of skin cancer. Early detection of melanoma is critical because it greatly increases the chances of successful treatment. However, many people lack the knowledge or skills to identify suspicious skin spots early, leading to delayed diagnosis and poorer health outcomes. This study addresses this gap by creating a user-friendly app that educates users on how to spot melanoma and assess their skin lesions accurately.
The researcher will follow a step-by-step process. First, they will conduct a review of existing melanoma detection guidelines, educational tools, and mobile health applications to identify effective features and gaps. Next, they will design and develop the mobile app, incorporating evidence-based content and interactive components such as quizzes, image analysis, and feedback. The target population will be adults aged 18-50, with a sample size of approximately 200 participants recruited through community clinics and online platforms. Participants will use the app over a specified period, after which their knowledge and skills in melanoma detection will be evaluated through pre- and post-intervention assessments, including questionnaires and practical tasks.
Data collected will include quantitative scores from knowledge assessments and qualitative feedback about the app experience. The analysis will involve statistical techniques like paired t-tests or ANOVA to determine improvements in detection skills and thematic analysis of qualitative data to assess user satisfaction and usability. The study aims to demonstrate that the app enhances users’ ability to identify melanoma signs effectively.
The expected contribution is a validated digital tool that can be scaled for wider use in public health education and early diagnosis initiatives. The findings will provide insight into mobile health interventions for skin cancer awareness and establish a framework for future digital health tools aimed at disease prevention. This research hopes to ultimately improve early melanoma detection rates and save lives through accessible, technology-driven education.
