OBJECTIVE
Systemic lupus erythematosus (SLE) is a chronic, multisystem autoimmune disease characterized by periods of remission and recurrent flares, which have been associated with stress.Despite the significance of stress in this disease, the Perceived Stress Scale-10 has yet to be psychometrically evaluated in patients with SLE.

METHODS
Exploratory factor analysis was used to examine the structural validity of the Perceived Stress Scale-10 among patients with SLE ( N?=?138) receiving medical care at Cedars Sinai Medical Center.Cronbach's coefficient alpha was used to examine internal consistency reliability, and Pearson product-moment correlations were used to examine convergent validity with measures of anxiety, depression, helplessness, and disease activity.

RESULTS
Exploratory factor analysis provided support for a two-factor structure (comparative fit index?=.95; standardized root mean residual?=. 04; root mean square error of approximation?=. 08). Internal consistency reliability was good for both factors (a?=. 84 and. 86). Convergent validity was evidenced via significant correlations with measures of anxiety, depression, and helplessness. There were no significant correlations with the measure of disease activity.

CONCLUSION
The Perceived Stress Scale-10 can be used to examine perceived stress among patients with SLE.
