Knowledge Gained and Retained from a Video-Centered, Community-Based Intervention for Ebola Prevention, Congo

Social mobilization, education, and prevention of the Ebola virus disease: A scoping review

The Ebola Virus Disease (EVD) remains a global public health concern with multiple outbreaks over the last five years. This scoping review aimed to synthesize the current state of knowledge on awareness, education, and community mobilization programs on EVD prevention. A comprehensive search strategy was executed in October 2021 across eight databases (APA PsycInfo, CINAHL, Cochrane CENTRAL, Embase, Global Health, MEDLINE, Scopus, and Web of Science). According to the PRISMA flow diagram, out of the 4815 studies generated by the search, 33 were retained for extraction and were included in this scoping review. Findings revealed that cultural practices that increased the risk of Ebola transmission remain very prevalent, even educational and awareness campaigns. Levels of Ebola-related knowledge by community members varied widely. A large proportion of the Ebola-affected populations were not aware of modes of transmission and half were unaware of signs and symptoms. Interventions with deep community mobilization, collaboration and engagement were effective in changing cultural practices, and reducing rates of infection. Interventions in the health sector helped increase willingness to practice preventive methods and the maintenance of social distancing and patient handwashing. A majority of the population members received their information about EVD from the community and mass media (in most instances, through broadcasting stations). Community interventions with a collaborative approach are effective to prevent EVD. It is needed to build trust between communities and health care, but also to use local resources and cultural factors combined with the use of technologies of information to prevent EVD.

Community engagement in Ebola outbreaks in sub-Saharan Africa and implications for COVID-19 control: A scoping review

OBJECTIVES

There is a paucity of scoping data on the specific roles community engagement played in preventing and managing the Ebola virus disease (EVD) outbreak in sub-Saharan Africa. We assessed the role, benefits, and mechanisms of community engagement to understand its effect on EVD case detection, survival, and mortality in sub-Saharan Africa. The implications for COVID-19 prevention and control were also highlighted.

METHODS

We searched for articles between 2010 and 2020 in the MEDLINE and Embase databases. The study types included were randomized trials, quasiexperimental studies, observational studies, case series, and reports.

RESULTS

A total of 903 records were identified for screening. A total of 216 articles met the review criteria, 103 were initially selected, and 44 were included in the final review. Our findings show that effective community involvement during the EVD outbreak depended on the survival rates, testimonials of survivors, risk perception, and the inclusion of community leaders. Community-based interventions improved knowledge and attitudes, case findings, isolation efforts, and treatment uptake.

CONCLUSION

Although the studies included in this review were of highly variable quality, findings from this review may provide lessons for the role of community engagement in the COVID-19 pandemic's prevention and control in sub-Saharan Africa.

Can High Exposure Help to Close Gaps? The Influence of COVID-19 Preventive Messages on Behavioral Intentions by Educational Attainment in Chile

The literature in the field of health communication has shown the existence of gaps between groups of different socioeconomic levels both in exposure to health campaign messages and in the influence these messages exert on individuals' health decisions. In this article, we examine the association between educational attainment and exposure to messages promoting COVID-19 preventive behaviors, namely, physical distancing, handwashing, and masks wearing in Chile. In addition, we model the association between exposure to these messages and the intentions to carry out the behaviors, as well as the differences attributable to educational attainment in the influence of exposure. A cross-sectional population survey combining online and telephone techniques was conducted among 3,592 adults in Chile. Regression analysis revealed that lower educational level and frequency of television use were positively associated with greater exposure to preventive messages. Exposure to preventive messages, in turn, was positively associated with intentions to maintain the three behaviors examined. Individuals in the lower educational attainment group had lower intentions to engage in two of the three behaviors, but those in these segments who were more exposed to preventive messages were as likely as their more educated counterparts to intend wearing masks and adhering to physical distance. The findings of this study underscore the importance of reaching the least educated segments with campaign messages in the context of public health crisis, since these messages can close gaps between the more and less educated group in their intentions to engage in preventive behaviors.

What influences people's responses to public health messages for managing risks and preventing infectious diseases? A rapid systematic review of the evidence and recommendations

BACKGROUND

Individual behaviour changes, such as hand hygiene and physical distancing, are required on a population scale to reduce transmission of infectious diseases such as COVID-19. However, little is known about effective methods of communicating risk reducing information, and how populations might respond.

OBJECTIVE

To synthesise evidence relating to what (1) characterises effective public health messages for managing risk and preventing infectious disease and (2) influences people's responses to messages.

DESIGN

A rapid systematic review was conducted. Protocol is published on Prospero CRD42020188704.

DATA SOURCES

Electronic databases were searched: Ovid Medline, Ovid PsycINFO and Healthevidence.org, and grey literature (PsyarXiv, OSF Preprints) up to May 2020.

STUDY SELECTION

All study designs that (1) evaluated public health messaging interventions targeted at adults and (2) concerned a communicable disease spread via primary route of transmission of respiratory and/or touch were included. Outcomes included preventative behaviours, perceptions/awareness and intentions. Non-English language papers were excluded.

SYNTHESIS

Due to high heterogeneity studies were synthesised narratively focusing on determinants of intentions in the absence of measured adherence/preventative behaviours. Themes were developed independently by two researchers and discussed within team to reach consensus. Recommendations were translated from narrative synthesis to provide evidence-based methods in providing effective messaging.

RESULTS

Sixty-eight eligible papers were identified. Characteristics of effective messaging include delivery by credible sources, community engagement, increasing awareness/knowledge, mapping to stage of epidemic/pandemic. To influence intent effectively, public health messages need to be acceptable, increase understanding/perceptions of health threat and perceived susceptibility.

DISCUSSION

There are four key recommendations: (1) engage communities in development of messaging, (2) address uncertainty immediately and with transparency, (3) focus on unifying messages from sources and (4) frame messages aimed at increasing understanding, social responsibility and personal control. Embedding principles of behavioural science into public health messaging is an important step towards more effective health-risk communication during epidemics/pandemics.

Effectiveness of a short web-based film targeting parental oral health knowledge in a well-child care setting

Young children rely on their parents with respect to oral health routines. However, parental knowledge on this topic is often insufficient. Well‐child care may be an excellent route to reach parents because almost all of them attend. To evaluate the effectiveness of an 8.5 min web‐based film about oral health, provided by well‐child care, a non‐blinded quasi‐experimental study was performed. Parents attending well‐child care clinics in the Netherlands were assigned to an intervention (n = 88) or control group (n = 41). The control group received care as usual. We measured parental knowledge of oral health with a questionnaire (range of scores 1–12) before and directly after the intervention, and 6 months later, and assessed differences between the intervention and the control group. Parental oral health knowledge improved after watching the film: the intervention group’s mean score of 11.1 (SD 1.3) was greater than the mean score of 7.1 (SD 2.0) of the control group (Cohen's d = 2.64). Scores remained higher in the intervention group 6 months after watching the film (mean 9.1, SD 1.3) than before (Cohen's d = 1.25). A web‐based educational film delivered in a well‐child care setting can be an effective way to address oral health and to improve parental knowledge.
