导言：遭受暴力是携带枪支的一个风险因素。遭受暴力的青年也难以设想未来的积极成果（例如，教育成果），随着时间的推移，这可能会增加携带枪支的可能性。然而，研究人员尚未研究随着时间的推移，暴力暴露的变化是否会影响枪支携带的发展轨迹。为了解决这一差距，我们（1）研究了暴露于暴力和枪支携带（等级9至12）之间的纵向关联，然后（2）研究是否在未来的期望的变化介导此纵向association.Method：暴露于暴力和枪支携带通过未来的期望之间的纵向关联进行了研究，从弗林特青少年研究的850名青少年。参与者来自美国中西部城市的四所高中。平行的潜在增长模型和潜在的增长mediation models.Results估计：一个积极的关联之间的变化率暴露于暴力和枪支携带。暴露于暴力也间接增加了枪支携带的风险随着时间的推移，降低未来的期望在9thgrade.Conclusions：我们的研究结果支持这一想法，帮助青年发展积极的态度教育的成功可能有助于减少枪支携带。增加对未来的积极期望可能有助于防止在暴力暴露的情况下携带枪支。
Introduction: Exposure to violence is a risk factor for firearm carriage. Youth exposed to violence also have difficulty envisioning positive future outcomes (e.g., educational outcomes), which can increase the likelihood of firearm carriage over time. Researchers, however, have not yet examined whether changes in exposure to violence over time can influence the developmental trajectories of firearm carriage. To address this gap, we (1) examined the longitudinal association between exposure to violence and firearm carriage (grades 9 to 12) and then (2) examined whether changes in future expectations mediated this longitudinal association.Method: The longitudinal association between exposure to violence and firearm carriage through future expectations was examined among 850 adolescents from the Flint Adolescent Study. Participants were recruited from four high schools in a midwestern city in the United States. Parallel latent growth models and latent growth mediation models were estimated.Results: A positive association was observed between the rate of change in exposure to violence and firearm carriage. Exposure to violence also indirectly increased the risk for firearm carriage over time by decreasing future expectation in the 9th grade.Conclusions: Our results support the idea that helping youth develop positive attitude about educational success may help reduce firearm carriage. Increasing positive expectations about future may help prevent firearm carriage within the context of violence exposure.
