OBJECTIVE: To investigate the prevalence of suicidal ideation among systemic lupus erythematosus (SLE) patients and to assess the psychological susceptibility of suicidal ideation.

METHODS: 324 SLE patients in Hefei city were interviewed with questionnaires, including Eysenck Personality Questionnaire (EPQ) and Trait Coping Style Questionnaire (TCSQ) and self-made questionnaire to collect information on suicidal ideation, social-demographic characteristics, etc. T test was used to compare the scores of personality and coping styles with national psychological norms. These odds ratios (95%CI) of the two factors for suicidal ideation were calculated by logistic regression, adjusted to socio-demographic factors.

RESULTS: Current suicidal ideation was present in 108(33.3%) of 324 SLE patients. The standard scores of neuroticism (49.81 ± 10.03, t = 15.327, P < 0.01) and psychoticism (49.84 ± 9.73, t = 3.142, P < 0.01) were both higher than norms (neuroticism: 41.27 ± 9.42; psychoticism: 48.14 ± 9.74). The standard score of extrovision and introvision (50.43 ± 9.90) was lower than norm (57.75 ± 8.26) (t = -13.317, P < 0.01). Both scores of positive coping (34.36 ± 7.86) and negative coping (28.87 ± 7.79) were higher than norms of female healthy group (PC: 29.32 ± 8.96, NC: 22.34 ± 7.47) (t values were 11.543 and 15.102, P values all < 0.01) and patients' group (PC: 29.15 ± 9.28, NC: 25.36 ± 8.42) (t values were 8.122 and 11.932, P values all < 0.01). After adjusting the social-demographic variables, neurotic personality (OR = 1.110, 95%CI: 1.072 - 1.149) and high level of negative coping (OR = 1.069, 95%CI: 1.030 - 1.109) were significantly correlated with suicidal ideation in SLE patients.

CONCLUSION: The rate of suicidal ideation in SLE patients in China was a little higher. Neurotic personality and negative coping were the psychological susceptibility of suicidal ideation in SLE patients.
