The effects of bullying are significant and can be long-lasting. When we think of these effects, however, we often think about the impact of bullying on the victim. The idea that bullying only affects victims is a common misconception. Bullying can have negative consequences for both the victim and the bully. These negative consequences can be both short- and long-term. 

Short-term effects

The victim – The effects of bullying on teens who are being bullied will differ from person to person, however, there are some common short-term impacts:

• Decreased school performance, including a sudden drop in grades
• Avoiding school
• Social isolation and withdrawal from usual activities
• Low-mood and pessimism
• Wanting to stay home more
• Reduced participation in after school activities
• More likely to become sick or ill
• Increased self-doubt and reduced self-esteem
• Increased feelings of loneliness, worthlessness and sadness

The bully – As with bully victims, teens who engage in bullying will feel the effects differently. This is partly dependent on the type of bullying they are engaging in. However, many of the effects are similar across the types of bullying:

• Decreased school performance, including a sudden drop in grades
• Getting in trouble, including increased school detentions and suspensions
• Expressing disregard for school rules and the law 
• Being excluded from some social groups
• Difficulties with social relationships, including conflict with peers
• Difficulties finding a genuine partner
• Conflict with parents and siblings
• Increased anxiety
• Feelings of anger and hostility
• For some, feelings of shame, guilt and embarrassment
