目的 对家属版重症监护疼痛观察工具（Critical-Care Pain Observation Tool for Families，CPOT-Fam）进行汉化和文化调适，并在ICU患者家属中检验其信效度。方法 按照Brislin翻译模型对CPOT-Fam进行直译和回译，经原作者审核、文化调适和预调查形成中文版CPOT-Fam，采用便利抽样法，选择2025年1月—3月入住杭州市某三级甲等医院成人综合ICU 100例患者的家属作为调查对象，验证量表的信效度。结果 中文版CPOT-Fam的内部一致性信度Cronbach’s α系数为0.786。家属采用CPOT-Fam与护士采用重症监护疼痛观察工具（Critical-Care Pain Observation Tool，CPOT）进行疼痛评分的总体一致性为高度（κ=0.681，95%CI：0.541~0.786），各条目一致性中，面部表情（κ=0.814）最高，肢体活动（κ=0.601）最低。CPOT-Fam的内容效度指数为0.99，CPOT-Fam各条目的内容效度指数为0.88~1.00。效标效度相关系数为0.783（P<0.001）。结论 中文版CPOT-Fam具有良好的信效度，可作为中国文化背景下ICU患者家属参与疼痛评估的有效工具。

Objective To translate and culturally adapt the Critical-Care Pain Observation Tool for Families （CPOT-Fam） and validate its psychometric properties among family members of ICU patients.Methods The CPOT-Fam was translated using the Brislin translation model，including forward and back-translation，followed by review by the original authors，cultural adaptation，and pilot testing to finalize the Chinese version. From January to March 2025，100 family members of adult patients in a general ICU of a tertiary hospital in Zhejiang Province were recruited via convenience sampling to validate the scale’s reliability and validity.Results The internal consistency reliability Cronbach’s α coefficient for the Chinese version of CPOT-Fam was 0.786. The overall agreement between family members（CPOT-Fam） and nurses（CPOT） for pain assessment was substantial（κ= 0.681，95%CI：0.541-0.786）. Among individual items，facial expression showed the highest agreement（κ=0.814），while body movements had the lowest（κ=0.601）. The scale-level content validity index（S-CVI） was 0.99，with item-level CVI（I-CVI） ranging from 0.88 to 1.00. The criterion validity correlation coefficient was 0.783（P<0.001）.Conclusion The Chinese version of CPOT-Fam exhibits satisfactory reliability and validity，serving as an effective tool for family members to participate in pain assessment for ICU patients in a Chinese cultural context.
