Grit and perseverance in suicidal behavior and non-suicidal self-injury

Data indicate persistence facilitates suicidal behavior. Non-suicidal self-injury (NSSI) is characterized by difficulty persisting while upset. The relationship between NSSI and suicidal behavior thus may hinge upon persistence. Participants were 604 undergraduates (79.5% women; 42.4% African American; 6.1% with 1 + prior suicide attempt). Data were collected online via self-report and analyzed using hierarchical multiple regression. As expected, higher levels of grit and perseverance predicted more frequent suicide attempts. Furthermore, grit and perseverance moderated the relationship between NSSI and suicide attempts, which increased in magnitude as individuals reported greater persistence. Findings depict suicidal behavior as a deliberate pursuit of death.
