Public ISBD [article]  inDevelopment and Psychopathology > 37-5 (December 2025) . - p.2432-2447 Titre : The association between nonsuicidal and suicidal self-injurious behaviors: A systematic review and expanded conceptual model Type de document : texte imprimé Auteurs : Brooke A. AMMERMAN, Auteur ; Taylor A. BURKE, Auteur ; Caitlin M. O’LOUGHLIN, Auteur ; Rebecca HAMMOND, Auteur Article en page(s) : p.2432-2447 Langues : Anglais (eng) Mots-clés : NSSI  mechanism  mediators  moderators  suicide risk  theory Index. décimale : PER Périodiques Résumé : Objectives:Nonsuicidal self-injury (NSSI) is one of the strongest predictors of suicidal behavior. Despite this, the field still has a limited understanding of the mechanisms by which this relationship is conferred.Method:We conducted a systematic review of the empirical research examining potential factors driving (i.e., moderators, mediators) the relationship between NSSI and suicidal behavior to address this gap in the literature.Results:We identified only 15 studies examining moderators or mediators of this relationship, examining 40 unique mediators and 22 unique moderators. Three prominent weaknesses were identified in the reviewed literature: (1) limited intersection with existing theoretical models of the NSSI - suicidal behavior relationship, (2) little replication of findings across studies (i.e., only four mediators and four moderators assessed in multiple studies), and (3) only one of the included studies utilized a prospective design. Research to date does little to improve our understanding of the theoretical or prospective relationship between NSSI and suicidal behavior, highlighting a foundational gap in the literature.Discussion:We propose the Nonsuicidal to Suicidal Self-Injury Pathway Model, a new conceptual model of the relationship between NSSI and suicidal behavior, drawing on extant theory and empirical research; we discuss future directions for work in this area.
