Stephen P. Lewis comments on Jeffrey D. Webster’s chapter “The Interplay of Adversity and Wisdom Development: The H.E.R.O.E. model” and how the H.E.R.O.E. model offers a lens to view self-injury recovery. Individuals who engage in self-injury are able to expand their emotion regulation and manage difficult emotions through recovery, along with refl...

Non-suicidal self-injury (NSSI) represents a prevalent and serious public health concern. Unfortunately, despite its widespread nature, NSSI remains misunderstood and stigmatized. In part, this may contribute to particular framings of NSSI as well as aspects of the NSSI experience. To this end, there are numerous elements of people’s NSSI experienc...

Background There has recently been a push for recovery-focused research in the eating disorder (ED) field, starting with a consensus definition of recovery. One definition, in particular, proposed by Bardone-Cone et al. [21] has received considerable attention given its transdiagnostic nature and validation studies. However, no studies to date have...

Language is a powerful form of communication that not only conveys ideas and knowledge but also can assign meaning and value to the world around us. As such, language has the power to shape our attitudes toward individuals, behaviors, and ideas, by labeling them (indirectly or not) as "good" or "bad." In this way, language can be used to propagate...
Article
Non-suicidal self-injury (NSSI) is the deliberate damage of bodily tissue which occurs without suicidal intent. NSSI is a common behavior among young people and a frequent focus in clinical practice. Many models of the aetiology and maintenance of NSSI are focused on emotion regulation. The role that cognition plays in the behavior is less well und...

Researchers often have personal experiences that motivate engagement with a research topic. We performed the first systematic investigation of self-relevant research (SRR; “me-search”) among psychologists. The prevalence of SRR and attitudes towards SRRers were examined in a representative North American sample (N = 1,778) of faculty, graduate stud...
Article
Stigma associated with non-suicidal self-injury (NSSI), the deliberate damage of one’s body tissue for non-lethal reasons, is highly complex, far-reaching, and can have profound effects (e.g., shame, low self-esteem, thwarted help-seeking) on individuals with lived experience of NSSI. In concert with calls for greater inclusion of people with lived...
