The link between violence and suicide is well documented. Previous studies, however, largely rely on cross-sectional designs or only consider violence as an antecedent of suicide. The purpose of the current study was to investigate the longitudinal relationship between violence and suicide from adolescence into young adulthood. Data were derived from Wave II (1995-1996), Wave III (2001-2002), and Wave IV (2007-2008) of the National Longitudinal Study of Adolescent Health (N = 8,966). We tested (2011-2013) a series of path analysis models in Mplus to determine the longitudinal associations between violence and suicidality. Results from the path analyses indicated that violence and suicidality mutually affect each other from adolescence into young adulthood. We found some evidence that the association between suicidality and violence was stronger for males compared to females, particularly in early and young adulthood. The current study confirms previous findings by demonstrating that violence is a risk factor for future suicide. We also extended the previous literature by demonstrating that a history of suicidality is associated with future risk for violence. Our findings highlight the importance of further integrating prevention efforts to reduce violence and suicidality during adolescence and early/young adulthood.
暴力与自杀之间的关系已有充分的文献记载。然而，先前的研究主要依赖于横断面设计，或者仅将暴力视为自杀的前因。本研究的目的是从青少年期到青年早期调查暴力与自杀之间的纵向关系。数据来自青少年健康全国纵向研究的第二波（1995-1996 年）、第三波（2001-2002 年）和第四波（2007-2008 年）（N=8966）。我们在 Mplus 中测试了一系列路径分析模型，以确定暴力和自杀意念之间的纵向关联。路径分析的结果表明，从青少年期到青年早期，暴力和自杀意念相互影响。我们发现一些证据表明，与女性相比，男性的自杀意念和暴力之间的关联更强，尤其是在早期和青年早期。本研究通过证明暴力是未来自杀的一个风险因素，证实了先前的发现。我们还通过证明自杀意念的历史与未来的暴力风险相关，扩展了先前的文献。我们的研究结果强调了在青少年期和早期/青年期进一步整合预防工作以减少暴力和自杀意念的重要性。
