Conceptual models of non-suicidal self-injury suggest the role of developmental vulnerabilities in mentalization; the ability to understand the mental states of self and others. The sample consisted of 197 participants between the age of 18-25 years, from English medium graduate and postgraduate colleges in Bangalore. They completed measures of NSSI-Functional Assessment of Self-Mutilation (FASM), dimensional personality pathology-Personality Inventory for ICD-11 (PiCD) and mentalization-Mentalization Questionnaire (MZQ). Among the participants, 28.9% reported having engaged in non-suicidal self-injury in the last 12 months, with 23.34% using 'moderate/severe methods' such as cutting, and 5.6% using only 'minor methods' such as self-hitting. Among the five dimensions of personality on the PiCD, emerging adults with a history of NSSI in the past year reported significantly higher levels of negative affectivity than their non-injuring peers. They also reported lower mentalizing abilities, particularly on the MZQ domains of 'refusing self-reflection,' emotional awareness,' and regulation of affect'. The relationship between negative affectivity and NSSI was mediated by mentalization. The implications for comprehensive assessment and interventions for emerging adults engaging in NSSI are discussed. 收起
