Transcultural Adaptation and Psychometric Evaluation of the Chinese Version of the Family Caregiver ICU Delirium Knowledge Questionnaire

Abstract

Objective: To test the reliability and validity of the Chinese version of the family caregiver ICU delirium knowledge questionnaire (C-CIDKQ) in mainland China. Methods: The Brislin translation model was used for standard translation and back-translation; cross-cultural adjustment of the translated scale was carried out through expert group discussion, communication with the original author and pre-investigation; convenience sampling method was used to study 214 family caregivers of ICU patients in a tertiary first-class general university hospital in Guangzhou city in southern China. Results: C-CIDKQ included three dimensions and 21 items: risk factor dimension (10 items), action dimension (6 items), and symptom dimension (5 items). The Cronbach’s alpha coefficients of the three dimensions of risk factor dimension, action dimension and symptom dimension were 0.713, 0.213 and 0.839, respectively, and the internal consistency reliability of the total scale was 0.777. Conclusion: C-CIDKQ has good reliability and validity and can be used as an ICU delirium knowledge evaluation tool for family caregivers of ICU patients in China. If the items of the action dimension are appropriately modified, the reliability and validity of the scale can be further improved.
