Abstract:
Objective:To evaluate the reliability and validity of the Chinese version of the Short Form of Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q-SF) for elderly patients.
Methods:The quality of life of 400 elderly outpatients from Kongjiang community health service center were evaluated by using the Chinese version of Q-LES-Q-SF. The reliability of the Chinese version of Q-LES-Q-SF was tested by the internal consistency reliability (Cronbach′s α coefficient) and the half confidence; the validity was tested by structural validity, convergence validity and distinguish validity and calibration validity.
Results:The Cronbach′s α coefficient of the internal consistency was 0.956; the Spearman-Brown coefficient of the half confidence was 0.894; the Guttman Split-half coefficient of odd even fold half confidence was 0.894. The exploratory factor analysis showed that there were 2 dimensions: the psychological dimension (Q2-8 items) and the physiological dimension (Q1, Q10-14). The confirmatory factor analysis showed that each psychological dimension factor load of Q2-8 was >0.50; each physiological dimension factor load of Q1, Q10-14 was >0.50. In distinguish validity, there was item with Z> 1.96 (P<0.05), showing that each item had a good distinction between different dimensions. In convergence validity, physiological and psychological dimensions of GFI were all >9.5, RMSEA were all <0.05. In calibration validity, the physiological and psychological dimensions of Q-LES-Q-SF had a good correlation with the corresponding dimensions of the SF-12 (P<0.05), and Pearson correlation value was 0.317 and 0.237, respectively.
Conclusion:The Chinese version of Q-LES-Q-SF has a good reliability and validity for elderly patients.
