Nonsuicidal self-injury in an adolescent population in Singapore

This mixed methods study examined the phenomenon of nonsuicidal self-injury (NSSI) of adolescents in Singapore. The researchers analyzed quantitative data to understand the functions of NSSI, the relationship of parental invalidation to NSSI, and the association between academic stress and parental invalidation. In addition, the researchers employed semi-structured qualitative interviews to provide supportive qualitative data. The participants were outpatients at the Child Guidance Clinic, Singapore, between the ages of 13 to 19 years old. Researchers compared 30 participants who engage in NSSI with 30 participants who do not engage in NSSI. The emotional regulation function was the most commonly endorsed function for NSSI. Adolescents who engage in NSSI have statistically significant (p < .01) higher mean parental invalidation scores than those who do not engage in NSSI. There is also a moderate, positive correlation between the level of parental invalidation and the level of academic stress for Singaporean adolescents. The researchers discuss the implications of this study for mental health professionals.
