Screening for anxiety and depression in clinical practice: translating scores from World Health Organization-5/Anxiety Symptom Scale-2/Major Depression Inventory-2 to Hospital Anxiety and Depression Scale

Abstract

Aim The aim of this study was to evaluate if a combination of World Health Organization-5 (WHO-5), Anxiety Symptom Scale-2 (ASS-2) and Major Depression Inventory-2 (MDI-2) can replace the Hospital Anxiety and Depression Scale (HADS) as screening tool for anxiety and depression in cardiac patients across diagnoses, and whether it is feasible to generate crosswalks (translation tables) for use in clinical practice. Methods We used data from the Danish ‘Life with a heart disease’ survey, in which 10,000 patients with a hospital contact and discharge diagnosis of ischemic heart disease (IHD), heart failure (HF), heart valve disease (HVD) or atrial fibrillation (AF) in 2018 were invited. Potential participants received an electronic questionnaire including 51 questions on health, well-being, and evaluation of the health care system. Crosswalks between WHO-5/ASS-2 and HADS-A, and between WHO-5/MDI-2 and HADS-D were generated and tested using item response theory (IRT). Results A total of 4346 patients responded to HADS, WHO-5, ASS-2, and MDI-2. Model fit of the bi-factor IRT models illustrated appropriateness of a bi-factor structure and thus of essential uni-dimensionality (RMSEA(p value) range 0.000-0.053(0.0099-0.7529) for anxiety, and 0.033-0.061(0.0168-0.2233) for depression). A combination of WHO-5 and ASS-2 measured the same trait as HADS-A, and a combination of WHO-5 and MDI-2 measured the same trait as HADS-D. Consequently, crosswalks (translation tables) were generated. Conclusions Our study shows that it is feasible to use crosswalks between HADS-A and WHO-5/ASS-2, and HADS-D and WHO-5/MDI-2 for screening cardiac patients across diagnoses for anxiety and depression in clinical practice.

“…A higher score indicates a greater level of anxiety and depression, and cut-off scores are available [ 69 ]. HADS is used in general medical settings, including occupational health, with sound psychometric properties [ 70 ].…”
