The Social-Ecological Model: A Framework for Prevention
The ultimate goal is to stop violence before it begins. Prevention requires understanding the factors that influence violence. CDC uses a four-level social-ecological model to better understand violence and the effect of potential prevention strategies. This model considers the complex interplay between individual, relationship, community, and societal factors. It allows us to understand the range of factors that put people at risk for violence or protect them from experiencing or perpetrating violence. The overlapping rings in the model illustrate how factors at one level influence factors at another level.
Besides helping to clarify these factors, the model also suggests that in order to prevent violence, it is necessary to act across multiple levels of the model at the same time. This approach is more likely to sustain prevention efforts over time than any single intervention.
The first level identifies biological and personal history factors that increase the likelihood of becoming a victim or perpetrator of violence. Some of these factors are age, education, income, substance use, or history of abuse. Prevention strategies at this level are often designed to promote attitudes, beliefs, and behaviors that ultimately prevent violence. Specific approaches may include education and life skills training.
The second level examines close relationships that may increase the risk of experiencing violence as a victim or perpetrator. A person’s closest social circle-peers, partners and family members-influences their behavior and contributes to their range of experience. Prevention strategies at this level may include parenting or family-focused prevention programs, and mentoring and peer programs designed to reduce conflict, foster problem solving skills, and promote healthy relationships.
The third level explores the settings, such as schools, workplaces, and neighborhoods, in which social relationships occur and seeks to identify the characteristics of these settings that are associated with becoming victims or perpetrators of violence. Prevention strategies at this level are typically designed to impact the social and physical environment – for example, by reducing social isolation, improving economic and housing opportunities in neighborhoods, as well as the climate, processes, and policies within school and workplace settings.
The fourth level looks at the broad societal factors that help create a climate in which violence is encouraged or inhibited. These factors include social and cultural norms that support violence as an acceptable way to resolve conflicts. Other large societal factors include the health, economic, educational and social policies that help to maintain economic or social inequalities between groups in society.
What are Social Norms?
Social norms refer to values, beliefs, attitudes, and/or behaviors shared by a group of people. They are often based on what people believe to be normal, typical, or appropriate. Social norms can function as unspoken rules or guidelines for how people behave, and for how people are expected to behave. People generally follow social norms because they want to fit in with the people around them.
Social norms can result in positive or negative outcomes. Sometimes social norms help people behave in ways that keep themselves – and others – safe and healthy.
Other times, social norms can have the opposite effect, and can lead people to behave in harmful ways.
Social Norms and Violence
Social norms can affect nearly any aspect of our lives. They contribute to our clothing choices, how we speak, our music preferences, and our beliefs about certain social issues. They can also affect our attitudes, beliefs, and behaviors related to violence.
The way we react to violence may be based on what we see other people do, or how we think other people would act. In other words, our reactions are based on what we believe is normal or appropriate.
People often misperceive (or misunderstand) social norms and overestimate the number of people who behave in unhealthy ways or who accept unhealthy behavior. Researchers have studied college students’ misperceptions of social norms related to alcohol use. They’ve found that most college students do not enjoy heavy drinking. However, they tend to think that heavy drinking is the norm among their peers and overdrink to fit in.
Misperceptions can be harmful when a person alters their own beliefs and behaviors based on a false assumption about other people’s beliefs and behaviors.
