The validation and study of the psychometric properties of the questionnaire for self-assessment of disease activity in patients with systemic lupus erythematosus (SLE) was carried out. The study included 129 patients with different levels of activity and variable clinical manifestations. Factor and cluster analysis revealed the internal structure of the questionnaire, reflecting the activity of SLE in the musculoskeletal system, internal organs, constitutional manifestations, nervous system and skin. The conducted Rush analysis allowed us to confirm the uniformity and internal validity of the questionnaire with satisfactory parameters of separation and reliability of items. The external validity of the questionnaire was confirmed by correlation with the values of SLE activity obtained using generally accepted indices. It was found that the perception of SLE activity by the patient is influenced not only by the obvious clinical manifestations of the disease, but also by a number of laboratory parameters.

Systemic lupus erythematosus, disease activity, activity index, questionnaire, validity, Rush analysis.
