RESUMEN

OBJECTIVE: To validate standard self-report questionnaires for depression screening in patients with rheumatoid arthritis (RA) and compare these measures to one another and to the Montgomery-Åsberg Depression Rating Scale (MADRS), a standardized structured interview. METHODS: In 9 clinical centers across Germany, depressive symptomatology was assessed in 262 adult RA patients at baseline (T0) and at 12 ± 2 weeks followup (T1) using the World Health Organization 5-Item Well-Being Index (WHO-5), the Patient Health Questionnaire (PHQ-9), and the Beck Depression Inventory II (BDI-II). The construct validity of these depression questionnaires (using convergent and discriminant validity) was evaluated using Spearman's correlations at both time points. The test-retest reliability of the questionnaires was evaluated in RA patients who had not undergone a psychotherapeutic intervention or received antidepressants between T0 and T1. The sensitivity and the specificity of the questionnaires were calculated using the results of the MADRS, a structured interview, as the gold standard. RESULTS: According to Spearman's correlation coefficients, all questionnaires met convergent validity criteria (ρ > |0.50|), with the BDI-II performing best, while correlations with age and disease activity for all questionnaires met the criteria for discriminant validity (ρ < |0.50|). The only questionnaire to meet the predefined retest reliability criterion (ρ ≥ 0.70) was the BDI-II (rs = 0.77), which also achieved the best results for both sensitivity and specificity (>80%) when using the MADRS as the gold standard. CONCLUSION: The BDI-II best met the predefined criteria, and the PHQ-9 met most of the validity criteria, with lower sensitivity and specificity.
