Description: Individuals who self-injure in the form of cutting, burning, hitting, inserting, and abrading present significant treatment challenges. This population utilizes high volumes of mental health and emergency services from which they often achieve little beneficial effect. Treatment is further complicated by the increasing awareness that the majority of women who self-injure have a history of early interpersonal trauma. Despite the empirically supported link between trauma and self-injury, there remains insufficient theoretical understanding that clearly articulates how self-injury arises from a history of early interpersonal trauma. Further, published treatment studies do not incorporate a history of trauma into the therapy for self-injury.The preliminary findings indicate that among a sample of women who have experienced early onset, severe, frequent, and prolonged childhood sexual abuse and self-injury, the CBGT intervention decreased the frequency of self-injury, improved maladaptive cognitive schema and negative affect, and diminished anxiety and depression. The intervention did not appear to affect frequency of health care utilization.The objectives of this study were to develop a conceptual model of self-injury and childhood sexual abuse, to develop a treatment manual informed by the model, and to pilot test the cognitive-behavioural group psychotherapy (CBGT) intervention. The model, grounded in the tradition of cognitive theory, illustrates how early trauma assists in evaluating and assigning meaning to situations through a belief system of powerlessness, meaninglessness, and badness/worthlessness. Internal and external stimuli trigger trauma-related schema and influence moment-to-moment negative evaluations of self, others, and the world. These evaluations result in overwhelming affect and physiological arousal that are interpreted as catastrophic and intolerable. Equipped with few other resources, one believes self-injury is the only option to provide relief. Consistent with the cyclical and tenacious nature of the behaviour, self-injury provides only temporary relief before a re-experiencing of further trauma-related cognitive, affective, and physiological arousal occurs.A one group repeated measures design was used to investigate the effectiveness of a 16 session intervention of CBGT for decreasing self-injury frequency. Eleven participants completed the study. Instrumentation included measures of self-injury frequency, trauma-related cognition and affect, anxiety, depression, and health care utilization.
