Evaluating the critical care family satisfaction survey for chronic critical illness.

Recognition of the family as a component of patient-centered critical care has shifted our attention to the assessment of family satisfaction in the intensive care unit (ICU). To date, there are no established measures of satisfaction with ICU care for family members of the chronically critically ill (CCI). This study evaluated psychometric properties of the Critical Care Family Satisfaction Survey (CCFSS) in 326 family members of the CCI using exploratory and confirmatory factor analysis (CFA). From the exploratory factor analysis, two unique structural models emerged, each with alpha coefficients of .72 to .91 and discriminant validity among factors (r < .70). The CFA confirmed the best-fitting structural model was a 14-item, three-factor solution (χ(2) = 354, df = 148, p < .001, Tucker Lewis Index = .88, Comparative Fit Index = .90, root mean square error of approximation = .06). Thus, the modified 14-item version of the CCFSS is reliable and valid in family members of CCI patients.
