ABSTRACT
Objective To investigate the reliability and validity of the medical outcomes by applying short form-36 (SF-36) in evaluating gout patients’ health related quality of life (HRQOL).Methods Gout patientswere enrolled between March 2016 and June 2016 in Foshan Hospital of Traditional Chinese Medicine.Patients completed the SF-36 questionnaire.Summary scores,physical component summary (PCS) and mental component summary (MCS) were calculated by summing factor-weighted scores across all 8 subscales,with factor weights derived from general population.The indicators of reliability and validity included internal consistency,test-retest reliability,structural and discriminant validity,ceiling and floor effect.Results Totally 306 patients were enrolled.The internal consistency test showed that the Cronbach α coefficients ranged from 0.782 to 0.822,and the test-retest reliability coefficients ranged from 0.720 to 0.986 (P<0.01).Structural validity analysis showed that there were two items whose eigenvalues were greater than one with the cumulative contribution rate of 66.1%.The discriminant validity analysis found that patients with more numbers of tophi,higher frequency of flare,multi-arthrosis involved and more complications had less scores of PCS and MCS (P<0.05).There was a high ceiling effect on physiological function and a higher ceiling and floor effect on role limitation and emotional function caused hy impaired physical health.Conclusion The SF-36 can be used for the assessment of HRQOL in Chinese gout patients but disease specific questionnaire are warranted.
