Abstract
ObjectiveTo evaluate the reliability and validity of the Chinese version of concise health status questionnaire (SF-36 scale) in evaluating the quality of life of patients with chronic Keshan disease, and to provide a scientific basis for studying the quality of life and the evaluation of treatment and rehabilitation of this population.
MethodsIn the August 2017, using cluster random sampling method, 175 patients with chronic Keshan disease treated by self-management of family beds in Pingliang City, Gansu Province in 2017 were selected as survey subjects, and demographic and disease data were collected. The Chinese version of SF-36 scale was used to investigate the quality of life. Split-half reliability and Cronbach's α coefficient were used to evaluate the reliability of the SF-36 scale; the factor analysis, correlation and differences between groups were used to evaluate the validity of the SF-36 scale.
ResultsThe split-half reliability value of SF-36 scale was 0.916, and the Cronbach's α coefficient was 0.869. Factor analysis extracted 3 common factors from 8 dimensions of SF-36 scale, and the cumulative contribution rate of the 3 common factors to the total variance was 72.08%. In addition to the correlation coefficient (r) between Role-Emotional and Bodily Pain dimension, the r value between total score and the scores of each dimension, and the scores of each dimension of SF-36 scale were 0.140 - 0.769. Except for the Bodily Pain dimension, there were statistically significant differences in the scores of Physiological Functioning, Role-Physical, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health dimension of the quality of life of patients with different grades of cardiac function (F = 4.66, 10.73, 6.77, 14.61, 5.58, 9.57, 7.10, P < 0.05).
ConclusionThe Chinese version of SF-36 scale has good reliability and validity in evaluating the quality of life of patients with chronic Keshan disease, and can be used to evaluate the quality of life of the patients.
