Information avoidance is a defensive strategy that undermines receipt of potentially beneficial but threatening health information and may especially occur when threat management resources are unavailable.
We examined whether individual differences in information avoidance predicted intentions to receive genetic sequencing results for preventable and unpreventable (i.e., more threatening) disease and, secondarily, whether threat management resources of self-affirmation or optimism mitigated any effects.
Participants (N = 493) in an NIH study (ClinSeq®) piloting the use of genome sequencing reported intentions to receive (optional) sequencing results and completed individual difference measures of information avoidance, self-affirmation, and optimism.
Information avoidance tendencies corresponded with lower intentions to learn results, particularly for unpreventable diseases. The association was weaker among individuals higher in self-affirmation or optimism, but only for results regarding preventable diseases.
Information avoidance tendencies may influence decisions to receive threatening health information; threat management resources hold promise for mitigating this association.
信息回避是一种防御策略，它会破坏对潜在有益但具有威胁性的健康信息的接收，并且可能尤其在威胁管理资源不可用时发生。
我们研究了信息回避方面的个体差异是否能预测接受可预防和不可预防（即更具威胁性）疾病的基因测序结果的意愿，其次，自我肯定或乐观等威胁管理资源是否能减轻任何影响。
美国国立卫生研究院（NIH）一项试点基因组测序使用情况的研究（ClinSeq®）中的参与者（N = 493）报告了接受（可选）测序结果的意愿，并完成了信息回避、自我肯定和乐观方面的个体差异测量。
信息回避倾向与了解结果的意愿较低相关，尤其是对于不可预防的疾病。在自我肯定或乐观程度较高的个体中，这种关联较弱，但仅针对可预防疾病的结果。
信息回避倾向可能会影响接受威胁性健康信息的决策；威胁管理资源有望减轻这种关联。
