An overview of the TwinsUK cohort’s anxiety and depression assessment, using the self-reported Hospital Anxiety and Depression Scale

Anxiety and depression are common mental health conditions that frequently coexist. The Hospital Anxiety and Depression (HADS) questionnaire, is a widely used questionnaire, both in the clinic and in research. HADS provides an assessment of anxiety and depression based on non-physical symptoms, hence it can be used in patients with other physical pain and symptoms. This resource provides an overview of all the HADS questionnaires completed by the twins in the TwinsUK registry. This includes both monozygotic and dizygotic twins, over a wide range of age and socioeconomic backgrounds. TwinsUK holds a wide range of phenotype and genotyping data that can be used as confounding factors in the study of mental health.
