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.
数据表明坚持会助长自杀行为。非自杀性自伤（NSSI）的特征是在心烦意乱时难以坚持。因此，NSSI与自杀行为之间的关系可能取决于坚持。参与者为604名本科生（79.5%为女性；42.4%为非裔美国人；6.1%有过1次及以上自杀未遂经历）。数据通过自我报告在线收集，并使用分层多元回归进行分析。正如预期的那样，更高水平的毅力和坚持不懈预示着更频繁的自杀未遂。此外，毅力和坚持不懈调节了NSSI与自杀未遂之间的关系，随着个体报告的坚持程度越高，这种关系的强度也会增加。研究结果将自杀行为描述为对死亡的蓄意追求。
