About
Dengue can be mitigated by both vector control and vaccination. Serious games in healthcare can be used to raise the community awareness of vector control in dengue prevention in a simulated interactive learning environment, by motivating serious game participants to optimise their own performance and influence their behaviour. The results show a specially designed serious game can better engage local residents by raising their awareness in vector control and proactiveness in dengue prevention. At least 8 out of 10 participants were willing to be vaccinated against dengue if they knew of the availability of a safe and effective vaccine.
Full description
Study design: From March to August 2021, a single-centre randomised controlled trial was conducted to determine the effectiveness of playing a serious game (intervention) in improving the KAP of participants in vector control and dengue prevention compared to those who viewed a dengue prevention website (control).
Study site: This study was conducted at a regional public primary care clinic (Polyclinic) in Sengkang. Sengkang Polyclinic is located in Sengkang Community Hub, which is an amenity centre in Sengkang, within the North-East region of Singapore. Sengkang is also a residential town, which is the second most populous in the region, being home to 244,600 residents in 2019.
Sample size calculation: To determine the effect of serious game in the literacy level of adults in preventing dengue in Singapore, the sample size was computed based on the study by Nurul Akmar Ghani et al, in which the significant difference in mean and standard deviation of knowledge scores were 14.55 (3.09) and 15.41 (2.75) respectively between the compared groups. To obtain a sample size with 95% confidence level and 80% power for this study, a minimum of 182 participants per group was required. With a possible drop out of 10%, the sample size was increased to 200 per group.
Recruitment and consent process: Recruitment posters, containing registration details of the study, were placed within the clinic's premises from March to August 2021. Adults who were interested to join the study voluntarily could approach the clinical research coordinators (CRCs), who would screen them for eligibility, explained the study intent and procedure to them in a designated room within the study site. The CRCs were trained by the principal investigator to provide adequate information and address relevant concerns or queries from the participants prior to the start of this study. The latter were informed about the purpose and content of the study based on the approved participant information sheet. After clarifying their doubts and queries, every eligible participant endorsed their written informed consent before randomization.
Randomization: The randomization sequence was created by the biostatistician using computer generated random numbers in a 1:1 ratio. Random permuted blocks were used to ensure equal number in each group. The randomization sequence was concealed in sequentially numbered, opaque, sealed envelopes by the principal investigator (PI) at the study site, and stored in a secured location that was accessible only by the research assistants. Blinding was not possible for the participants and the CRCs, as the intervention group would be required to download an application into the mobile phone. Both the biostatistician and PI were not involved in the enrolment or randomization process of participants in this study.
Study procedure: The KAP assessment instrument was adapted from a previous study conducted by Nurul Akmar Ghani et al.
Participants in both groups completed the first (baseline) questionnaire via a secured online platform, Form.sg. Form.sg was used to create online questionnaires that capture classified data for this study. The platform does not store participants' response data in its servers and all responses are sent directly to the study team's dedicated email address.
Participants in the intervention group installed a mobile application, 'Sam's Mozzie Adventure' and were instructed to complete the game within 2 weeks.
Participants in the control group accessed the National Environmental Agency 'Stop Dengue' website and were instructed to complete reading the dengue prevention information within 2 weeks.
Both groups completed the second questionnaire, containing the KAP assessment and a question pertaining to individual's interest to vaccinate against dengue, within 2 weeks after the intervention. In addition, participants in the serious game group evaluated the game with the adapted Systems Usability Score.
Analysis: The knowledge, attitude and practice scores varied from 0-16, 0-15, 0-15 respectively, with a maximum score of 46 points. The highest achievement attained by the participants in serious game group were measured by the number of stars awarded in-game, which varied from 0-48 stars. The data were audited and errors were rectified before analyses. Descriptive statistics in terms of frequency (n), percentage (%), mean and standard deviations (SD) were used to express the data. The socio-demographic variables between the two groups were compared using Chi-Square test for categorical variables and independent t-test for continuous variables. Independent t-test was used to compare the baseline, follow up and change in KAP scores between the control and intervention group. Paired t-test was used to determine the difference in scores from baseline and follow up. The Spearman's correlation was used to determine the association between change scores and maximum game stars awarded in the intervention group. SUS score was presented in frequency and percentages. A p-value of less than 0.05 is considered statistically significant. All analyses were performed using IBM SPSS 27.0.
