Abstract Objectives:To examine the responsiveness, reliability, and validity of Chinese version of Systemic Lupus Erythematosus Questionnaire (SLAQ). Methods:A cross-sectional observational study was designed for this research. The principal attributes evaluated were linguistic and cultural adaption, reliability, and validity.Standardized response means and acceptability were calculated to estimate the responsiveness of the SLAQ. Cronbach’s alpha was used to evaluate its reliability. The Spearman correlation coefficient was used to assess the criterion validity by calculating the association with measurement of other lupus disease activity.ResultsThe response rate for the pilot study was 99.9%. The mean time to complete the questionnaire was 6.7±2.8 min. The Chinese version of SLAQ had good reliability, with a Cronbach’s alpha of 0.857. Cronbach’s alpha for the test-retest reliability was 0.878. For validity, the SLAQ was correlated with SLAM, SLEDAI-2000 and SLEDAI-no lab. The correlation was good at 0.832, 0.506 and 0.668 respectively.Conclusion:The Chinese version of the SLAQ questionnaire has adequate responsiveness, reliability, and validity in our cohort, and it is a helpful and meaningful tool for assessing disease activity in lupus patients without laboratory results.

Fatigue Severity

Background: Fatigue is one symptom of Systemic Lupus Erythematosus (SLE), which has an important effect on the quality of life. Fatigue Severity Scale (FSS)is one parameter fatigue symptom in SLE. The purpose of this study was to determine the validity and reliabilitybetween FSS with duration of ilness and disease activity of SLE patients in Indonesia.Methods: FSS performed on 40 patients with SLE. FSS original English version has been converted-translated into Indonesian version by a team of RheumatologyImmunology Medical Faculty of Brawijaya University. Reliability determined by Cronbach’s Alpha values (>0.6). Validity was determined by the value of Corrected Item-Total Correlation which each item was a valid question if below value of Cronbach’s Alpha.Results: The reliability value was determined by Cronbach’s Alpha values (>0.6) in which the SLE patients in this study had a Cronbach’s Alpha value of 0.946. Value of Corrected Item-Total Correlation overall under Cronbach’s Alpha value (range = 0.684-0.859) which indicates that each item was a valid question. There were correlation between the FSS Indonesian version with disease duration (p = 0.000) as well as the value of r = 0.581, with SLEDAI (p = 0.000) with a value of r = 0.833. Conclusion: FSS in Indonesian version has a good reliability and validity and can be used by clinicians andother researchers to assess the condition of fatigue in SLE patients in Indonesia.Keywords: validity, reliability, fatigue, fatigue severity scale, systemic lupus erythematosus
