Introduction

Hospital Anxiety and Depression Scale (HAD) - Free online screening test. Developed by Zigmond et al., HAD is primarily used for comprehensive screening of anxiety and depressive moods. It consists of two subscales (HA and HD) with a total of 14 items - 7 assessing anxiety and 7 assessing depression. Each item is scored 0-3, with higher scores indicating more severe anxiety or depressive symptoms. Research has shown HAD has good reliability and validity.

Scale Interpretation

Higher scores may indicate more severe symptoms. As this is only an auxiliary screening tool, test results are for reference only.
