Self-harm and suicidal behavior in women with comorbid PTSD and substance dependence.

This study examined the frequency, methods, and correlates of self-harm and suicidal behavior in 65 outpatient women with comorbid posttraumatic stress disorder (PTSD) and substance dependence (SD). Results showed high rates of suicide attempts, self-harm, suicidal ideation, and self-harm ideation for the prior three months. The most common methods were overdosing and cutting/scratching. Both PTSD and SD were perceived as contributing to self-harm and suicidal behavior. Women who had and had not engaged in such behavior differed in SD diagnoses and reasons for staying safe, but not in the number or type of traumatic experiences, age at first trauma, or substance abuse diagnoses.
