Clin Psychol Psychother. 2020 Apr 21;: Authors: Shahwan S, Lau JH, Abdin E, Zhang Y, Sambasivam R, Lin TW, Gupta B, How OS, Ann CS, Subramaniam M Abstract Non-suicidal self-injury (NSSI) is a behavioural concern and can present in diverse ways, varying by method, frequency, severity, and function etc. The possible combinations of these features of NSSI produces an array of profiles that makes evaluation and management of this behaviour challenging. The aim of this study was to build upon previous work that reduces the heterogeneity of NSSI patterns by using Latent Class Analysis (LCA) to identify a typology of NSSI. Participants consisted of 235 outpatients aged 14-35 years attending a tertiary psychiatric hospital in Singapore who had reported at least one NSSI behaviour within the last year. Eight indicators captured using the Functional Assessment of Self-mutilation were used in the LCA: frequency of NSSI, length of contemplation before engaging in NSSI, usage of >3 NSSI methods, suicidal ideation, and four psychological functions of NSSI i.e. social-positive, social-negative automatic-positive, and automatic-negative. The LCA revealed 3 distinct groups: Class 1- Experimental/Mild NSSI, Class 2- Multiple functions NSSI/Low Suicide Ideation, Class 3- Multiple functions NSSI/Possible Suicide Ideation. Multinomial logistic regression analyses wer...
