Nonsuicidal Self-Injury in Adolescents: Characterization of the Disorder and the Issue of Distress and Impairment

Nonsuicidal self-injury disorder (NSSID) is a condition in need of further study to assess the validity of the potential diagnosis and its suggested criteria. This study examined the NSSID diagnosis and investigated the distress/impairment criterion by comparing community adolescents who metall criteria for NSSID (n=186) to adolescents with five or more nonsuicidal self-injury (NSSI) episodes (n=314), and to a group of adolescents who metall criteria but negated that their NSSI caused them any distress or impairment, thus failing to meet criterion E (n=29). The NSSID group delimited from the 5 NSSI group by reporting significantly more frequent and severe self-injurious thoughts and behaviors, as well as having more experiences of negative life events and higher levels of trauma symptoms. There were also some differences between the NSSID group and adolescents without distress/impairment, which together contribute valuable information on the potential NSSID diagnosis, as well as the discussion of criterion E.
