Non-suicidal self-injury (NSSI) is a deliberate destruction of one’s own body tissue without suicidal intention that causes physical injury. NSSI is mostly found in adolescents or young adults (Paul, Tsypes, Eidlitz, Ernhout, & Whitlock, 2015). Borderline personality disorder (BPD) is one of the risk factors for developing NSSI. Individuals with borderline personality disorder also experience invalidation during their childhood, this can cause individuals with BPD to feel that they deserve to receive NSSI as a form of self-punishment (Sadeh et al., 2014). In addition, children who experience parental separation (through death, divorce or employment) have a higher risk factor for developing NSSI (Astrup, Pedersen, Mok, Carr, & Webb, 2017). A literature search was conducted in six databases, and a total of 20 relevant articles were found. The explanation of the relationship between non-suicidal self-injury, borderline personality disorder, and loss of or separation from a parent are explored in this study, in order to increase understanding of how NSSI behaviours can be prevented.
