One of the most problematic aspects to manage in groups, and in classrooms specifically, is social contagion . Social contagion refers to how a behavior, such as self-harm, can spread among members of a group. We might identify it when, for example, there are two cases in the same group within a 24-hour period, or a significant number of cases within the same group, such as a class.

In schools, social contagion can occur when there is a case of self-harm. To prevent it, it is recommended to limit the information students receive about a particular case. For example, it can be helpful to talk to the person who has self-harmed and get them to agree not to share this information with their classmates, or to prevent any visible injuries.

On the other hand, it would be advisable to provide students with information and resources on self-harm , in a broader context of learning emotional regulation skills (without relating it to the identified young person).
