Abstract:
Objective To evaluate the reliability and validity of Chinese multi-dimensional health assessment questionnaire (MDHAQ-C) in patients with systemic lupus erythematosus (SLE) in China.Methods One hundred and twelve SLE patients were recruited in the evaluation.The reliability of the questionnaire was tested by intra-class coefficient (ICC) and Cronbach's alpha.Convergent validity and divergent validity were assessed by Spearman correlation coefficient of MDHAQ-C with health assessment questionnaire (HAQ),the 36-item short-form health survey (SF-36) and the hospital anxiety and depression scales(HAD).Discriminant validity was tested in groups of patients with varied disease activities and status of damage.Results The Cronbach's alpha was 0.886 in the function scale (FN) and 0.774 in the scale of psychological status (PS).The corrected item-total correlation ranged from 0.409-0.866.The ICC was 0.615-0.920(P＜0.05).MDHAQ-C correlated with the questionnaires satisfyingly in most scales (from P＜0.5 to P＜0.001).The scores of MDHAQ-C could discriminate different groups of patients (P＜0.05).Conclusion MDHAQ-C is a reliable,valid instrument for functional measurement and quality of life assessment in Chinese SLE patients.
