Background: Coronavirus disease 2019 (COVID-19) is a public health concern worldwide. This study aimed to assess the preventive behaviors, barriers, and drivers, including the knowledge and self-efficacy of COVID-19 in Malaysia. Methods: A cross-sectional study was conducted during the COVID-19 outbreak by using a self-administered questionnaire. The instrument used was adopted from the World Health Organization resources. Descriptive statistics were used to describe the categorical data. Chi-square and independent t-test were performed to evaluate the associations between the variables and preventive behaviors. Results: A total of 465 (97.3%) respondents were recorded. The mean age was 34.3 ± 11.8 years old. A high percentage of the respondents (99.4%) were aware of the COVID-19 outbreak, and their knowledge mean score was 18.74 (Standard Deviation [SD]: 2.51). The mean scores of self-efficacy, barriers, and drivers were 11.07 (SD: 1.72), 5.20 (SD: 2.81), and 39.71 (SD: 5.17), respectively. Barriers (Odds Ratio [OR]: 1.10; 95% Confidence Interval [CI]: 1.01, 1.21; p < 0.05) and drivers (OR: 1.12; 95% CI: 1.07, 1.17; p < 0.001) were found to be predictors for social distancing practices. Conclusions: Knowledge and self-efficacy were found to be at good levels, whereas self-efficacy, barriers, and drivers were revealed to be the predictive factors in determining the preventive behaviors. Adherence to preventive measures was largely affected by the behavioral drivers.

Background: Compliance with preventive health behavior is crucial during dental visits. This study investigated using an audio device to increase dental patients’ preventive health behavior. Methods: A randomized control study was conducted in private dental practices. The test group listened to an audio device containing public health messages related to COVID-19 and preventive health behavior. The control group listened to relaxing instrumental music with no public health messages. Results: A total of 65 participants (age 18–77 years) were allocated to each group. About 63% of the participants in the test group performed preventive health behaviors compared to the control group, but the difference was not significant. Significant differences in preventive health behavior were observed in both groups before and after treatment (p < 0.001). A significant difference in the awareness level was detected between the test and control group (p < 0.01). No significant differences were found in the knowledge and self-efficacy scores between the two groups (p > 0.05). Conclusions: An audio device used during dental treatment effectively delivered public health messages to improve preventive health behavior. Hence, an audio device can be used as alternative media to deliver public health information during dental visits.
