People with high anxiety tend to interpret ambiguous cues negatively, regardless of whether the cues are negative or positive. Cognitive bias modification for interpretation (CBM-I) may reduce such biases. However, CBM-I sessions for social anxiety in previous studies were held either only once or twice a week in the laboratory and did not test the Japanese population. In this study, we developed a Japanese version of CBM-I. The current study investigated the effects of a short, intensive program using two types of the Japanese version of CBM-I procedures. In Study 1, 74 participants were randomly placed into either a one-week program with online sessions of text-based scenarios training or a control condition. In Study 2, 120 participants were randomized into one-week online sessions of text-based scenarios training (four times) and picture-word cue training (three times) or a control condition. In both Study 1 and 2, participants in the control condition completed the same positive interpretation task after a one-week standby. In Study 1, individuals in the positive condition demonstrated significant improvements in depressive symptoms from pre-intervention to post-intervention compared to those in the control condition. Improvements in depressive symptoms and interpretation bias at a one-month follow-up were significant. In Study 2, in the positive condition, there was a significant reduction in negative affect compared to the control condition. In addition, there were greater reductions in negative affect, social evaluative fear, and negative interpretation bias at a one-month follow-up, irrespective of condition. Results suggest that text-based CBM-I affects depressive symptom and interpretation bias, text, and picture-based CBM-I especially affects these emotional characteristics. Depending on the assessment and treatment policy for patients, we might concurrently use two approaches, one with text stimuli when stimulating depressive symptoms and interpretations, and the other with picture stimuli when stimulating emotions.高焦虑个体倾向于对模糊线索做出负面解读，无论线索本身带有负面还是正面属性。认知偏差解读矫正（Cognitive bias modification for interpretation, CBM-I）可有效缓解此类解读偏差（interpretation bias）。但既往研究中，针对社交焦虑（social anxiety）的CBM-I干预均仅在实验室开展，且频次为每周1至2次，且未在日本人群中完成验证。本研究开发了日文版CBM-I，旨在探究采用两种日文版CBM-I流程的短程强化干预项目的效果。 在研究1中，74名参与者被随机分配至两组：一组接受为期一周的基于文本场景训练的线上课程，另一组为对照组。在研究2中，120名参与者被随机分为两组：一组接受为期一周的线上训练，包含4次文本场景训练与3次图片-词语线索训练，另一组为对照组。 两项研究中的对照组参与者，均在为期一周的等待期后完成了相同的正面解读任务。 研究1结果显示：与对照组相比，正面干预组参与者的抑郁症状（depressive symptoms）在干预前至干预后阶段出现显著改善；在1个月随访时，抑郁症状与解读偏差的改善效果仍保持显著。 研究2结果显示：与对照组相比，正面干预组参与者的负性情绪（negative affect）出现显著降低；此外，无论分组归属如何，在1个月随访时，参与者的负性情绪、社会评价恐惧（social evaluative fear）与负面解读偏差均出现了更为显著的缓解。 本研究结果表明，基于文本的CBM-I可有效改善抑郁症状与解读偏差，而结合文本与图片的CBM-I则对上述情绪特征的改善效果尤为显著。针对患者的评估与治疗方案，我们可同时采用两种干预范式：当需改善抑郁症状与解读偏差时，采用文本刺激范式；当需调节情绪状态时，则采用图片刺激范式。
