Validity of Self-rating Screening Scales for the Diagnosis of Depression and Anxiety in Adult Patients With Bronchiectasis

Background: There are no previous studies aimed at assessing the validity of the screening scales for depression and anxiety in adult patients with bronchiectasis. Aims: To analyze the psychometric properties of Hospital Anxiety and Depression Scale (HADS), Beck Depression Inventory (BDI) and Hamilton Anxiety Scale and to evaluate the concordance for the diagnosis of depression and anxiety between these screening scales and the structured clinical interview in adult patients with bronchiectasis. Method: Cross sectional study. 52 patients with bronchiectasis completed HADS, BDI and Hamilton Anxiety Scale; afterwards, were individually interviewed by a mental health care professional using the structured Mini International Neuropsychiatric Interview (MINI), which evaluates for depression and anxiety according to DSM-IV criteria. Results: Based on MINI, 18 subjects (34.6%) had a diagnosis of depression and 25 (48.1%) had anxiety. Optimal cut-off values to detect depression were >= 9 for the HADS-D (sensitivity 0.833, specificity 0.971, AUC 0.962 [95% CI 0.918-1]), and 17 for BDI (sensitivity 0.889, specificity 0.912, AUC 0.978 [95% CI 0.945-1]). Optimal cut-off values to detect anxiety were >= 4 for the HADS-A (sensitivity 0.960, specificity 0.593, AUC 0.833 [95% CI 0.723-0.943]), and 17 for Hamilton Anxiety Scale (sensitivity 0.800, specificity 0.852, AUC 0.876 [95% CI 0.781-0.970]). Conclusion: The self-rating screening scales HADS, BDI and Hamilton Anxiety Scale are reliable tools to screen for depression and anxiety in adult patients with bronchiectasis. However, the use of specific cutoff values may improve the diagnostic accuracy of the previous scales in this specific group of patients. (C) 2020 SEPAR. Published by Elsevier Espana, S.L.U.
