The internet and self-injury: what psychotherapists should know.

The Internet affords information gathering and sharing previously impossible. For individuals who practice self-injury, this capacity allows rapid identification of others with shared history, experience, and practices. For many of those who self-injure, the ability to find others like themselves reduces the isolation and loneliness that so often characterizes the behavior.

Female habitual self-mutilators.

Data are presented on 240 female habitual self-mutilators. The typical subject is a 28-year-old Caucasian who first deliberately harmed herself at age 14. Skin cutting is her usual practice, but she has used other methods such as skin burning and self-hitting, and she has injured herself on at least 50 occasions.

Self-mutilation and eating disorders.

Patients with eating disorders are at high risk for self-mutilation (e.g., skin cutting and burning), and vice versa.

The plight of chronic self-mutilators.

Self-mutilation is a more common behavior than generally realized; its prevalence may be 750 per 100,000. From the responses of 250 subjects to a Self-Harm Behavior Survey we have learned that self-mutilation typically begins in early adolescence and may assume a chronic course characterized by severe psychosocial morbidity. Some chronic self-mutilators already are heavy and generally dissatisfied users of mental health services.
