Self‐injurious behaviors (SIBs), including both suicidal and nonsuicidal self‐injury, are major public health problems that have been on the rise in recent decades. There are few effective SIB interventions, and those that are effective cannot reach most people who are in need of help–that is, these interventions are not scalable. To address this need, we recently developed a scalable, app‐based treatment called Therapeutic Evaluative Conditioning (TEC) that preliminary studies have shown causes reductions in SIBs (Franklin et al., 2016). Although TEC was developed and evaluated as a standalone, self‐administered intervention, it may also be a valuable therapeutic tool within traditional clinical settings. Here we provide a case illustration of a young adult female who presented at an outpatient clinic with a long history of self‐injurious behaviors and multiple failed treatment attempts. In discussing this case, we describe how to implement TEC within such a setting and what might be expected as a result.
