To ensure the accuracy of self-reported data, it is important to reduce potential sources of bias such as the unwanted influence of prior questions on subsequent questions, the so-called item context effect. This article attempts to replicate the finding that evaluative subjective well-being was affected by a preceding item, a question about the political atmosphere in the country; it also examines manipulations that could mitigate the impact of the context-inducing item on well-being. Study 1 used a sample of 4,500 participants recruited from Amazon’s Mechanical Turk; it examined the effect of three manipulations based on adding buffer questions or adding text to reorient participants’ attention. A context effect was found, and one manipulation mitigated the context effect. Study 2 used a nationally representative sample (n = 906); it only replicated the context effect. These results reaffirm the importance of carefully considering item context effects in survey research.

为了确保自我报告数据的准确性，重要的是减少潜在的偏见来源，例如先前问题对后续问题的不良影响，即所谓的项目上下文效应。本文试图复制评估主观幸福感受前一项影响的发现，即有关该国政治气氛的问题；它还检查了可以减轻情境诱导项目对幸福感的影响的操作。研究 1 使用了从亚马逊的 Mechanical Turk 招募的 4,500 名参与者的样本；它检查了基于添加缓冲问题或添加文本以重新定向参与者注意力的三种操作的效果。发现了上下文效应，并且一项操作减轻了上下文效应。研究 2 使用了具有全国代表性的样本（n = 906); 它只是复制了上下文效果。这些结果重申了在调查研究中仔细考虑项目背景效应的重要性。
