Self-injury is a deviant behavior often understood as the intentional infliction of harm onto one’s own body that exists absent of suicidal. This study uses a qualitative methodology to examine the etiology and perpetuation of self-injury using the terminology of relevant social-psychological theories to determine which processes best describe a causal pathway leading to self-injury and its perpetuation after the onset of the behavior. Data obtained from 16 semi-structured interviews with former and current self-injurers indicate that the processes described in general strain theory, social learning theory, and social control theory are all important for understanding the etiology and perpetuation of self-injury. Analytic induction was utilized as the method of analysis in order to parse out only the elements universal to pathways to self-injury evident in all of the examined cases. All participants used self-injury as coping response for mitigating negative affect stemming from strain, thus, implicating general strain theory as important for understanding the onset of self-injury. Participants were categorized into two subtypes of self-injurers based upon the temporal dimension of the social learning process. Future research should attempt to use quantitative methodologies to provide generalizability for the results of this study and examine how changes in risk and protective factors over the life-course modify one’s propensity to engage in self-injury
