Objective. To explore the array of concepts important to patients with chronic systemic lupus erythematosus (SLE) and
to compare these with instruments assessing disease activity, damage, and health status.
Methods. We conducted a qualitative focus-group study of patients with SLE concerning their problems in daily
functioning. The group sessions were tape recorded, transcribed, and divided into meaning units. The concepts contained
in these meaning units were extracted and linked to the International Classification of Functioning, Disability and Health
(ICF). We then compared the concepts from the focus groups with those concepts covered by SLE activity scores, the
Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), and the
Short Form 36 Health Survey (SF-36).
Results. A total of 92 concepts emerged from 5 focus groups; of these, 28 related to body functions and structures, 24 to
activities and participation, and 25 to environmental factors. Two concepts were linked to the health condition itself and
6 to personal factors. Seven were not covered by the ICF. Of the 28 concepts regarding body functions and structures, 24
(86%) were covered by the combination of activity scores and the SDI. The SF-36 also addressed 3 of these concepts and
contained 9 (38%) of 24 concepts in activities and participation.
Conclusion. Although the combination of SLE activity scores, SDI, and SF-36, as suggested for SLE studies, well covers
body functions and structures and includes a significant portion of problems regarding activities and participation,
neither environmental nor personal factors are covered at all.
KEY WORDS. Systemic lupus erythematosus; International Classification of Functioning, Disability and Health; Patient
perspective.
INTRODUCTION
The World Health Organization’s International Classifica-
tion of Functioning, Disability and Health (ICF) (1) is a tool
used to better characterize the full array of problems a
patient faces when affected with disease (2– 4). Specifying
these problems is a particular challenge in a disease such
as systemic lupus erythematosus (SLE) because of the
wide variety of organ systems involved and its variable
activity and severity.
SLE is a prototypical autoimmune disease with an inci-
dence and prevalence varying considerably in different
countries (5,6). The burden of the disease is elevated
