Accumulating evidence suggests that trauma exposure is positively associated with future engagement in risky behavior, such as substance misuse, aggression, risky sex, and self‐harm. However, the psychological factors driving this association and their relevance across gender groups require further clarification. In a community sample of 375 adults with a high rate of trauma exposure (age range: 18–55 years, M = 32.98 years, SD = 10.64; 76.3% assaultive trauma exposure), we examined whether emotional reactivity linked lifetime assaultive trauma exposure with past–month risky behavior. We also explored whether this model differed for cisgender women (n = 178, 47.6%) and men (n = 197, 52.5%). As hypothesized, assaultive trauma was positively related to emotional reactivity, β = .20, SE = 0.03, t(369) = 3.65, p < .001, which, in turn, partially accounted for the association between assaultive trauma and past‐month risky behavior, indirect effect: β = .03, SE = 0.01, 95% bootstrapped CI [0.01, 0.06]. Gender moderated this association such that assaultive trauma was indirectly associated with risky behavior via emotional reactivity for women but not for men, index moderation: B = ‐0.03, SE = 0.02, 95% bootstrapped CI [‐0.07, ‐0.01]. Cross‐sectional results suggest that emotional reactivity may be a proximal target for clinical intervention to aid in the reduction of risky behavior among women.

将攻击性创伤与危险行为联系起来的情绪反应：顺性别女性和男性之间差异的证据

越来越多的证据表明，创伤暴露与未来从事危险行为（如药物滥用、攻击性、危险性行为和自残）呈正相关。然而，驱动这种关联的心理因素及其跨性别群体的相关性需要进一步澄清。在由 375 名创伤暴露率较高的成年人组成的社区样本中（年龄范围：18-55 岁，米=32.98岁，标清= 10.64；76.3% 的攻击性创伤暴露），我们检查了情绪反应是否将终生攻击性创伤暴露与过去一个月的危险行为联系起来。我们还探讨了这个模型对于顺性别女性是否有所不同（n= 178, 47.6%) 和男性 (n =197, 52.5%）。正如假设的那样，攻击性创伤与情绪反应呈正相关，β = 0.20，东南欧= 0.03,t(369) = 3.65,p< .001，这反过来又部分解释了攻击性创伤与过去一个月的危险行为之间的关联，间接影响：β = .03，东南欧= 0.01，95% 自举 CI [0.01，0.06]。性别调节了这种关联，使得攻击性创伤通过女性的情绪反应与危险行为间接相关，但对于男性则不然，指数调节：乙=‐0.03，东南欧= 0.02，95% 自举 CI [‐0.07，‐0.01]。横断面结果表明，情绪反应可能是临床干预的最接近目标，以帮助减少女性的危险行为。
