Abstract

In this study, we investigated the relationships between forms, age of onset, and repetition of non-suicidal self-injury (NSSI).

RESULTS showed that 38 participants (18.36%) engaged in NSSI. The results of quantification theory type III showed that the forms of NSSI, such as carving words or pictures, sticking, and preventing wounds from healing, were associated with early age of onset. In addition, NSSI without tools, such as biting, scratching, punching self, and banging head, was repetitive. On the other hand, NSSI such as self-cutting was performed especially in women, and occurred mainly once. Therefore, it was shown that NSSI has different age of onset and repetition, which are associated with suicide risk, depending on its forms. In preventive education and early treatment of NSSI, it was suggested that non-typical forms of NSSI also should be considered.
