Bullying and mental health

Bullying is a form of aggressive behavior where one person, the bully, deliberately and repeatedly tries to harm or dominate another person, the victim. It’s considered a form of abuse.

There’s often a power imbalance involved in bullying. Bullies may use their size, strength, popularity, or other advantages to control or intimidate others. They may also spread hurtful rumors or gossip about their victims.

Research suggests that around 20% of US students ages 12 to 18 experience bullying, but schools aren’t the only place where it happens.1 Bullying can also take place online, in the workplace, or even at home.

Types of bullying

Bullying takes many forms. Some are obvious, but others are subtle and harder to spot.

Physical bullying is usually the easiest to notice because it involves hurting somebody else’s body or doing damage to their property. It can include hitting, kicking, shoving, spitting, or breaking a victim’s belongings.

Verbal bullying involves saying mean or hurtful things to someone with the goal of intimidating, insulting, or humiliating them. Examples include name-calling, teasing, threatening, or making racist or sexist remarks. This type of bullying can be more difficult to pin down because it may be interpreted as jokes or banter.

Social bullying, also called “relational bullying,” involves trying to damage someone’s reputation or social status by excluding them from groups, spreading rumors about them, or deliberately making them feel left out or isolated. Boys and girls are equally likely to engage in social bullying.2

Cyberbullying takes place online, usually through social media or text messages. It can include sending threatening or hurtful messages, posting embarrassing photos or videos, or creating websites or social profiles that mock or humiliate someone. Because cyberbullying can be so public and long-lasting—and can be done anonymously—some experts believe it does more damage than traditional bullying.3

Workplace bullying involves mistreatment or aggression in a professional setting: for instance, a manager bullying a direct report or an employee bullying a coworker. It may include verbal abuse, threats, work sabotage, withheld information, excessive monitoring, or unfair criticism. About 30% of workers (and 43% of remote workers) report that they’ve been bullied.4

Why do bullies bully?

There’s no single answer to this question. Some bullies act out to improve their status or get what they want. Some may be trying to cope with their own feelings of insecurity, anxiety, or low self-esteem. Others may have witnessed bullying in their own families or experienced it themselves, and some people bully just because they think it’s funny or cool. Whatever the reason, bullying is never acceptable.

Bullies tend to be motivated by one or more of the following factors:

Needing power and control: A bully may want to feel like they have more power over a specific person or group of people, or in general. They may also want people to respect and fear them.

Looking for attention: Some bullies crave the spotlight they get from abusing others. The positive—and even negative—attention they get for their behavior can be addictive and validating.

Wanting to fit in: In some cases, people bully to feel more like they belong to a particular group or social circle. They may believe that hurting people or being aggressive will help their peers accept them.

Reacting to stress: Some people bully as a way of relieving their own stress or anxiety. They may believe bullying others will make them feel better about themselves or their situation.

Getting revenge: Some people bully to get back at people they think wronged them in some way. This can be in response to real or perceived wrongdoings.

Bullying is a learned behavior. In many cases, bullies learn from their families, friends, or peers that it’s acceptable. They may also see bullying on TV, in movies, or in video games and think it’s a normal or harmless way to treat others.

Do bullies have a mental health disorder?

Bullying isn’t a disorder on its own, but it’s been linked to mental health conditions like attention-deficit hyperactivity disorder (ADHD), anxiety, and depression.5 Children who bully others may also be at risk of developing personality disorders later in life.

Children who bully others and are bullied themselves, known as bully-victims, are at an even higher risk of mental health problems than children who are exclusively bullies or victims.6 Bully-victims may experience young adulthood depression, panic disorder, agoraphobia (mainly among young women), and suicidal ideation (mainly among young men).7
