Development of Usable Mobile Application for Colorectal Cancer Community Education
The awareness of colorectal cancer risk and participation in screening is still low among Malaysian despite increasing trend of new cases. As the consequence of that, more than half of new cases were detected in late stage. Improvement of disease knowledge may increase screening participation hence disease can be detected early. Currently, health risk was disseminated to the public via education material in the form of pamphlets in health clinic or health campaign. However, with the advancement of communication technology today, reading through pamphlet has becoming less popular. People nowadays prefer to read from their smartphone using web browser or mobile applications. Despite huge increment in smartphone ownership and availability of mobile apps, little is known about the technology implementation in health promotion and education especially in Malaysia.
The aim of this paper is to document the process of designing and developing a mobile app for community education on colorectal cancer as well as to assess the usability of the application prototype.
The mobile application designing and development includes two part which are the content development using nominal group technique (NGT) and development of the mobile application prototype. NGT was a group of discussion involving experts and target-users to determine the information to be included in the prototype and the features of the prototype that is expected for a user-friendly mobile application. The mobile application prototype has been developed using framework Ionic 1 that is based on the Apache Cordova and Angular JS. After that, it has been published in the Google Play store for the target user to download, tested and assess the usability using validated SKAMA questionnaire. One sample T-test was used to assess the usability score with cut-off value for usable mobile application is 68.
The ColorApp (Colorectal Cancer Awareness Application) was successfully developed in local Malay language. The NGT discussion had suggested 6 main menus in the ColorApp prototype which are Introduction, Sign and Symptoms, Risk Factors, Preventive Measures, Colorectal Cancer Screening Program, and iFOBT Kit. Two additional menus were added to allow user-ColorApp interaction and as part of its artificial intelligence properties which are Analyse Your Status and ColorApp Calculator. The prototype has been published in Google Play store. The mean(SD) usability score was 72(11.52) indicates that ColorApp is a usable mobile application for health education and promotion on colorectal cancer.
ColorApp mobile application can be used as a tool for community education on colorectal cancer.
