Methods of Self-Injury Mediate Emotion Dysregulation and Acquired Capability for Suicide.

Theories of suicide suggest what moves people from suicidal ideation to suicidal behavior is ability to overcome distress and pain associated with suicide. This capability (AC) is thought to be acquired through exposure to painful or provocative stimuli (Joiner, 2005). Emotion dysregulation predicted AC (b = -0.021, SE = 0.011, p = .046), and NSSI (b = 0.014, SE = 0.003, p \u3c .01) while NSSI predicted AC (b = 0.576, SE = 0.196, p \u3c .01). The indirect effect of NSSI methods on emotion dysregulation and AC was significant (b = 0.008, BootSE = 0.005, CI95 = [0.001, 0.019]. Four percent of the relationship between emotion dysregulation and AC occurs through the number of NSSI methods
