Types
Risk communication takes place on different scales, of which have different features and methods.Community risk communication
Risk communication on a community-wide scale mainly falls into specific categories. Some of the most well-studied areas of risk communication are climate change, nutrition, and natural disasters like floods. With the rise of COVID-19 in 2019, risk communication strategies utilized by governments to their communities were heavily critiqued. In the modern day, most people in groups get their information from the internet before anything else, so the sending of risk communication messages has methodologically changed.Individual risk communication
One of the most common causes for the enactment of risk communication is medical-based personal issues. In a 2015 study, risk communication to people who had family members with dementia took place, and a model was developed that heavily features shared decision-making processes. In these cases where families of patients are involved, there is no general message that is sent out to the public. Instead, what often happens is that an intervention takes place between the medical experts and the family.Methods
Risk communication and community engagement
Risk communication and community engagement (RCCE) is a method that draws heavily on volunteers, frontline personnel and on people without prior training in this area. The World Health Organization advocated for this approach during the early recommendations for public health mitigation of the COVID-19 pandemic.Substantive harm analysis
Another way to do risk communication analysis is to test the risks. Specifically, testing on the four main types of harm outlined by Löfstedt. These four types of harm, in relation to risk communication, are death, illness or injury, lack of resources, and injury to social status. The next step is then to test those risks of harm in three different fields to get a sense of the overall scope of the possible harm.Challenges
Problems for risk communicators involve how to reach the intended audience, how to make the risk comprehensible and relatable to other risks, how to pay appropriate respect to the audience's values related to the risk, how to predict the audience's response to the communication, etc. A main goal of risk communication is to improve collective and individual decision making. Some experts coincide that risk is not only enrooted in the communication process but also it cannot be dissociated from the use of language. Though each culture develops its own fears and risks, these construes apply only by the hosting culture. These differences stem from epistemological barriers, as well as social construction ones. When there are varying community-based beliefs in a situation, the importance of the risk at hand is also varied, as different communities have different perceptions of how impactful a result might be.Government risk communication
Some challenges with risk communication by governments stems from whether or not the communities being communicated to even want to know about the risks they are facing. In a 2013 study, Canadian citizens reacted positively when their government communicated risks they had individual control over, but found communicating minute risks that had no individual control over irrelevant and unnecessary. When someone is irritated by a risk communication message, it is likely that their "gut feeling" is impacted, leading to a possible misunderstanding of the situation.Nutrition risk communication
Unlike other risk communication areas, there is not a definite unambiguous relationship between the intake of food and the effect on the human body. This has led to conflicts between suppliers and consumers when a controversy comes to light. Among professional nutritionists, there is debate on whether certain diets or foods are in fact good or bad for humans, as everyone's body can react differently to food intake. Studies have retained that nutrition risk communication has been poor over time, as the strategies employed may be too similar to those employed in nuclear disaster situations. When this strategy is employed, those who receive the risk communication messages can become irritated, as they feel the actual scope of the danger does not match the message.References
