PurposeTo assess the psychometric properties of the Chinese version of the 23-item Patient Satisfaction in the Intensive Care Unit (PS-ICU-23) and 24-item Family Satisfaction in the Intensive Care Unit (FS-ICU-24) questionnaires.Materials And MethodsPatients (n = 243) discharged from an intensive care unit (ICU) in Hong Kong and family members (n = 237) completed the translated questionnaires. We used confirmatory factor analysis to assess the construct validity and measurement equivalence across groups (gender, mechanical ventilation, casemix, length of stay in ICU), coefficient alpha for internal consistency (reliability) and concordance correlation coefficient (ρc) for agreement between patients' and family members' perspective on satisfaction.ResultsA three-factor model provided a better fit than the two-factor model for both PS-ICU-23 and FS-ICU-24 questionnaires. Factorial equivalence was present across groups in both questionnaires. Internal consistency was adequate for PS-ICU-23 (coefficient alpha overall domain 0.85; care subscale, 0.83; information subscale, 0.90; decision-making process subscale, 0.67) and for FS-ICU-24 (coefficient alpha overall scale 0.86; care subscale, 0.84; information subscale, 0.89; decision-making process subscale, 0.65). Overall ICU satisfaction agreement was moderate (0.40).ConclusionsBoth Chinese PS-ICU-23 and FS-ICU-24 questionnaires have sound psychometric properties but family satisfaction may not be a good proxy for patient satisfaction in ICU.Copyright © 2019 Elsevier Inc.
