Brief Summary

The goal of this study is to evaluate the effectiveness of Acceptance and Commitment Therapy (ACT) for individuals who engage in nonsuicidal self-injury(NSSI) and have comorbid anxiety.

With the data collected from the study, the investigators will test the following hypotheses:

Acceptance and commitment therapy will lead to reductions in anxiety and self-harm behaviors in non-suicidal self-injury individuals.

Detailed Description

Non-suicidal self-injury is the direct and purposeful harming of one's bodily tissue outside of social and religious norms and lacking suicidal intent. The most common NSSI behaviors include cutting (70-90%), banging or hitting (21-44%), and burning (15-35%) (Rodham & Hawton, 2009); but many report utilizing multiple methods (50-70%; Klonsky, 2011; Whitlock, Eckenrode, & Silverman, 2006). NSSI has an alarming prevalence among college students, with rates ranging from 17-38% (Whitlock et al., 2006; Gratz, Conrad, & Roemer, 2002). NSSI occurs in the context of many psychological disorders (Nock, 2010), and is associated with anxiety and mood disturbances (Andover et al., 2005). This is a prevalent problem and lacks an efficacious treatment. As a result, this study can shed insight into possible treatments.

The experiential avoidance model of deliberate self-harm posits that a function of self-injury is maintained through negative reinforcement by reducing unpleasant emotional arousal (Chapman et al. 2006). Therefore a treatment that directly targets reducing experiential avoidance is likely to be effective.

ACT is based on the theory that rigid attempts to control internal states, thoughts and feelings, and other forms of experiential avoidance contribute to symptom development and maintenance of anxiety and self-injury. The training includes three components: (a) educating Ps about the exacerbation of anxiety symptoms and problem behaviors through rigid attempts at experiential avoidance, (b) introducing acceptance and the willingness to experience anxiety-related sensations and cognitions as an alternative to experiential control, through the practice of intentional and non-judgmental paying attention to one's thoughts, feelings, images and bodily sensations (including aversive symptoms of anxiety) and learning to see thoughts as an ongoing process distinct from self rather than merely an event with literal meaning (cognitive defusing), and (c) instructing Ps in between-session exercises incorporating awareness of present, internal experiences and cognitive defusion exercises while engaging in exercises that give rise to them.
