Temperament and character in patients with systemic lupus erythematosus.

BACKGROUND: In addition to identified neuropsychiatric characteristic of systemic lupus erythematosus (SLE), changes in personality seem to occur in patients with SLE. Even in absence of an axis I psychiatric diagnosis, personality variations play important role in general wellbeing of these patients. This study investigated personality features in patients with SLE using Temperament and Character Inventory (TCI).

METHOD: In this case-control study personality features of 59 patients with confirmed diagnosis of SLE were evaluated using Persian version of TCI-125 questionnaire. Collected data from patients with SLE were statistically compared with normative data for Iranian population.

RESULTS: Among four subscales of temperament, reward dependence (RD) and harm-avoidance (HA) were significantly lower than general population. Self-directedness (SD) character dimension was significantly lower in SLE patients compared to normative data. No significant difference was noted in novelty-seeking (NS) and persistence (PS) temperament scales and cooperativeness (CO) and self-transcendence (ST) character scales.

CONCLUSION: Personality changes in SLE is characterized by higher HA and RD along with low SD. These features are associated with higher anxiety, social withdrawal and lower resourcefulness and purposefulness.
