The public have shown increasing interest in having health information disseminated to them through smartphones. The current usage of health-related smartphone apps was over 500 million people. In addition, studies have shown that the use of gamification produced positive effect on users' engagement in learning about health and led to positive change in the behaviour for their health and wellness. Several previous studies have shown the effectiveness of mobile applications in promoting health related information. A pilot randomized control trial among coronary heart disease (CHD) patients found that participants in the intervention group (Care4Heart app) showed better overall CHD knowledge levels than participants in the control group (website of Singapore Heart Foundation).~For dengue fever, an integrated mobile health app (Mozzify) was developed and may improve knowledge on dengue fever and promote dissemination and sharing of information on dengue fever among the public and health practitioners. During the development, suggestions to improve the engagement of the app included the addition of games to encourage the public to use it more frequently. Adding to this, the concept of gamification is increasingly being used in health education applications since 2010. Studies have shown that the use of gamification produced positive effect on users' engagement in learning about health and led to positive change in the behaviour for their health and wellness.~As both mobile applications and gamification show increasing importance in the field of mHealth, the DengueAid app was developed to improving monitoring of the disease and knowledge on dengue fever. Previous studies on the effectiveness of a gamified mobile app to improve dengue knowledge was limited to none. In this era of digitalization, an effective gamified mobile intervention for dengue fever which consistently affect the Malaysian population should be developed. Hence, for this study, the effectiveness of DengueAid in improving dengue knowledge among the public will be evaluated through a randomized control trial (RCT).~The sample size was decided on based on previous literature involving the use of a gamified mobile application to improve knowledge on oral health. For a full RCT, using mean and standard deviation values from a previous study (Control Group 13.1 ± 1.6, Intervention Group 14.3 ± 2.0) with 90% power and alpha of 0.05, the estimated sample size is 48 in each arm. Considering a 20% dropout rate the final number of participants recruited would be 116 (58 in each arm).~The study will be advertised on a social media platform (Facebook). Lay public who are interested to join the study will click on a link in the advertisement. The participants will then read the study information sheet and undergo an eligibility check to determine if they are suitable to join the study. Participants who have hearing and speech impairment, cognitive impairment, had dengue before and healthcare staff would be excluded from the study. Participants who are eligible would then have to complete a consent form and provide sociodemographic details. They will then be randomized using an online randomizer to either intervention or control groups. They will be given three days to complete using the intervention/control materials.~Participants in both study arms, would be given three days to complete the online education material (intervention: DengueAid app; control: MyHEALTH website). The research assistant will send an online questionnaire three days after the enrollment day. The questionnaire consists of questions on knowledge on dengue fever based on the modules and content of the DengueAid app as well as questions on health-seeking intention. The questionnaire will be developed using REDCap. Each participant will be compensated with RM30 once they completed the post-intervention online questionnaire.
Dengue is an endemic infectious disease in Malaysia. Delays in seeking treatment and improper self-care contribute to dengue complications and mortality. A mobile app (Dengue Aid) was developed to educate and empower patients to perform evidence-based self-care when having dengue fever. DengueAid is hypothesised to improve people's knowledge and health-seeking intention on dengue. This will be evaluated via an online randomised controlled trial. Adults aged 18 and above who have Facebook, an android smartphone and understand either English or Malay language will be recruited through Facebook advertisements. Eligible participants would be randomized to either using the DengueAid app (intervention) or MyHEALTH website (control). An online randomizer tool will be used to randomize participants into the intervention or control group. Participants in both arms would complete a post-intervention online questionnaire (knowledge and health-seeking intention) three days after recruitment.
