ABSTRACT
The functions of nonsuicidal self-injury (NSSI) and DSM-IV-TR diagnoses were examined in a sample of thirty ethnic adolescents followed up in a local child and adolescent psychiatric clinic in Singapore. The most commonly endorsed function of NSSI on the Functional Assessment of Self-Mutilation scale was Automatic Negative Reinforcement (A-NR) and the least being Social Negative Reinforcement (S-NR). Participants were more likely to be diagnosed as having Major Depression Disorder. Depressed adolescents did not differ from non-depressed counterparts in their endorsement of social reinforcement functions. The results suggest that specific psychosocial interventions may help address both automatic and social functions of NSSI in Singapore adolescents.
