Non-suicidal self-injury (NSSI) has been noted as a significant risk factor for possible suicide attempts. According to the Interpersonal Psychological Theory of Suicide, individuals can attempt suicide after they have acquired the capability to commit it. The acquired capability for suicide can be defined as one's habituated level to the pain and fear associated with suicidal behaviors. This is obtained through constant exposure to painful and provocative events, NSSIs being a prime example. This article reviews prior related studies to determine the extent to which the acquired capability for suicide can be utilized as a predictive factor for fatal suicide attempts following NSSIs. Our review finds a total of 11 studies that directly or indirectly support the claim that the acquired capability for suicide should be considered as a relevant factor linking NSSIs and suicide attempts. Given that NSSIs are most frequently observed in clinical settings, our findings suggest that the acquired capability for suicide will be a useful indicator for clinicians to predict the risk of future suicide attempts by patients.
