Theory and research suggest that objective features of a threatening situation and individual differences influence threat responses. We examine three ways individual traits may relate to a threat response: (a) directly and independent of objective threat features, (b) indirectly through relationships with threat perception, or (c) as moderators of the relationship between objective threat features and responses. Using integrative data analysis (IDA), we aggregated data across three studies examining hurricane preparation intentions. Analysis supported two of the potential pathways. Supporting the first path, both openness and extraversion had direct, positive relationships with preparation likelihood. Supporting the second path, agreeableness, conscientiousness, and social conservatism positively related to preparation likelihood through a positive relationship with threat perception, whereas impulsivity and sensation-seeking negatively related to preparation likelihood through a negative relationship with threat perception. This work shows the pivotal role individual differences play regarding responses to uncertain threats.

理论和研究表明，威胁情况的客观特征和个体差异会影响威胁反应。我们研究了个体特征可能与威胁响应相关的三种方式：（a）直接且独立于客观威胁特征，（b）通过与威胁感知的关系间接，或（c）作为客观威胁特征与响应之间关系的调节器。使用综合数据分析 (IDA)，我们汇总了三项检查飓风准备意图的研究的数据。分析支持两种潜在途径。支持第一条路径，开放性和外向性都与准备可能性有直接、积极的关系。支持第二条路，随和，尽责，和社会保守主义通过与威胁感知的正相关关系与准备可能性正相关，而冲动和感觉寻求通过与威胁感知的负相关关系与准备可能性负相关。这项工作显示了个体差异在应对不确定威胁方面的关键作用。
