Self-injury can occur in either sex and in any race of people. The behavior is not limited by education, age, sexual orientation, socioeconomic status, or religion. However, there are some common factors among people who engage in self-injury. Self-injury occurs more often among:

  • Adolescent females (although a growing number of adolescent males are engaging in SI)
  • People who have a history of physical, emotional, or sexual abuse
  • People who have co-existing problems of substance abuse, obsessive-compulsive disorder, or eating disorders
  • Individuals who were often raised in families that discouraged expression of anger
  • Individuals who lack skills to express their emotions and lack a good social support network
