The statement format of the Decisional Conflict Scale (sf-DCS) is designed and widely used to assess patients' state of uncertainty during health related decision making. As yet no Mandarin version of the sf-DCS has been produced. This study aims to produce the first Mandarin version of the sf-DCS and test its validity and reliability in mainland China.
The translation and cross-cultural adaptation of the original English version of the sf-DCS into Mandarin was carried out in accordance with previously published guidelines. The psychometric properties of sf-DCS were assessed in two hypothesized decision-making contexts through online surveys.
In the online survey designed to test scale validity and reliability, 437 people responded to the influenza immunization survey and 238 responded to the breast cancer screening survey. The results confirm that the Mandarin version of sf-DCS has good criteria validity and the exploratory factor analysis suggested a fitted revised five factors model by removing three items. Respondents who were "unsure" about their decisions/intentions, had read less information, and reported lower self-perceived prior knowledge level scored higher on sf-DCS. The Cronbach's alpha for the sf-DCS total score was 0.963 and that for each subscale ranged from 0.784 to 0.937 in both decision making contexts, and the test-retest correlation coefficient was 0.528.
The Mandarin version of sf-DCS has good criteria validity and its internal consistency is satisfactory. Our analysis suggests a refinement of the original sf-DCS's factor structure is needed.
决策冲突量表（sf-DCS）的陈述格式旨在评估患者在与健康相关的决策过程中的不确定性状态。目前尚未有 sf-DCS 的简体中文版。本研究旨在生成 sf-DCS 的第一个简体中文版，并在中国内地测试其有效性和信度。
按照先前发表的指南，将 sf-DCS 的原始英文版本翻译成简体中文。通过在线调查，在两个假设的决策情境中评估 sf-DCS 的心理测量特性。
在旨在测试量表有效性和信度的在线调查中，437 人回应了流感免疫接种调查，238 人回应了乳腺癌筛查调查。结果证实，sf-DCS 的简体中文版具有良好的标准效度，探索性因子分析建议通过删除三个项目来拟合修正的五因素模型。对决策/意图不确定、阅读信息量较少且报告自我感知先验知识水平较低的受访者，sf-DCS 得分较高。在两种决策情境中，sf-DCS 总分的克朗巴赫 α 值为 0.963，每个分量表的范围为 0.784 至 0.937，重测相关系数为 0.528。
sf-DCS 的简体中文版具有良好的标准效度，其内部一致性令人满意。我们的分析表明，需要对原始 sf-DCS 的因子结构进行细化。
