The relationship between dissociative symptoms, alexithymia, impulsivity, sexual abuse, and self-mutilation.

The overall purpose of the present study was to further our understanding of the mechanisms of self-mutilative behavior in a sample of female inpatients. The study found that self-mutilators (n = 103) displayed a greater degree of dissociative symptoms and alexithymia and a greater number of self-injurious behaviors, as well as higher rates of childhood sexual abuse, than nonmutilators (n = 45). In addition, the study found that among these variables, the number of self-injurious behaviors had the strongest relationship to self-mutilation. However, both dissociative symptoms and alexithymia were independently associated with self-mutilative behavior. Implications of our findings for clinicians and researchers are discussed.
