Abstract:

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.
