Assessment of the psychometric properties of patient-reported outcomes of depression and anxiety in systemic lupus erythematosus.

OBJECTIVES: This study aimed to: 1) determine the prevalence of depression and anxiety in SLE patients using the Center for Epidemiological Studies-Depression Scale [CES-D], Hospital Anxiety and Depression Scale [HADS], and Beck Anxiety Inventory [BAI] questionnaires; 2) study the criterion validity, interpretability, and test-retest reliability of CES-D, HADS and BAI; and 3) evaluate their diagnostic accuracy when compared to the assessment of an independent psychiatric assessment using the Mini-International Neuropsychiatric Interview (MINI). METHODS: 159 consecutive SLE participants were screened for depression and anxiety using the CES-D, HADS, and BAI, and underwent the MINI. Sensitivity and specificity were evaluated against the MINI. Test-retest reliability was studied. Receiver operator characteristic (ROC) curves were utilized to determine the cut-off scores for CES-D, HADS and BAI. RESULTS: The prevalence of depression ranged from 29% (HADS-D) to 52% (CES-D) and the prevalence of anxiety ranged from 45% (BAI) to 50% (HADS-A). ROC showed similar performance for CES-D and HADS-D. The diagnostic accuracy of HADS-A outperformed BAI. Furthermore, these self-reported questionnaires demonstrated good to excellent test-retest reliability. Analyses exhibited optimal cut-offs for CES-D (26), BAI (19), HADS-A (6), and HADS-D (8) that optimized their sensitivity and specificity as screening metrics for depression and anxiety in SLE patients. CONCLUSIONS: Anxiety and depression are highly prevalent in patients with SLE. Patient-reported outcome questionnaires such as the CES-D, HADS, and BAI may be useful tools to screen for depression and anxiety in SLE. Our results suggest that SLE-specific cut-offs may improve diagnostic accuracy of current screening metrics in patients with lupus.

The Assessment of Anxiety and Depression and its Associated Factors in SLE.

BACKGROUND: Depression and anxiety are common neuropsychiatric complaints in patients with Systemic Lupus Erythematosus (SLE). While numerous studies have been performed to investigate the prevalence, impact, and associated factors of depression and anxiety, current literature presents mixed results. In particular, the prevalence of anxiety and depression varies substantially between studies due to methodological limitations, and heterogeneity in defining anxiety and depression, patient selection, and metrics used. Moreover, there is a lack of studies evaluating the validity, reliability, and interpretability of commonly used screening tools for depression and anxiety in SLE patients. RESULT AND CONCLUSION: Further investigations should aim to reach a consensus surrounding the role of controversial associated factors in depression and anxiety of SLE patients, while also focusing on the identification of novel factors that have not yet been highlighted in the literature.
