Although induced changes in interpretation bias can lead to reduced levels of stress reactivity, results are often inconsistent. One possible cause of the inconsistencies in the effects of interpretation bias modification (IBM) on stress reactivity is the degree to which participants engaged in emotion regulation while being exposed to stressors. In this study, we distinguished between the effects of IBM on natural, unregulated stress reactivity and the effects of IBM on people's ability to up- or downregulate this stress reactivity.
Both in the context of general anxiety (Experiment 1, N = 59) and social anxiety (Experiment 2, N = 54), we trained participants to interpret ambiguous scenarios in either a positive or a negative manner, and we assessed the effects on unregulated and regulated stress reactivity.
Although we found relatively consistent training-congruent changes in interpretation bias in both experiments, these changes had no effect on either unregulated or regulated stress reactivity.
In both experiments, we used healthy student samples and relatively mild emotional stressors.
In line with previous research, our findings suggest that the effects of IBM on unregulated stress reactivity may be small and inconsistent. Differences in the extent to which participants engaged in emotion regulation during stressor exposure are unlikely to account for these inconsistencies.
尽管诱导解释偏差的改变可以导致应激反应水平降低，但结果往往不一致。解释偏差修正（IBM）对应激反应影响不一致的一个可能原因是参与者在暴露于应激源时进行情绪调节的程度。在这项研究中，我们区分了 IBM 对自然、不受调节的应激反应的影响，以及 IBM 对人们调节这种应激反应能力的影响。
在一般焦虑（实验 1，N=59）和社交焦虑（实验 2，N=54）的背景下，我们训练参与者以积极或消极的方式解释模棱两可的情景，并评估对不受调节和受调节的应激反应的影响。
尽管我们在两个实验中都发现了相对一致的训练一致的解释偏差变化，但这些变化对不受调节或受调节的应激反应都没有影响。
在两个实验中，我们都使用了健康的学生样本和相对温和的情绪应激源。
与先前的研究一致，我们的发现表明，IBM 对不受调节的应激反应的影响可能较小且不一致。在应激源暴露期间参与者进行情绪调节的程度的差异不太可能解释这些不一致。
