The aims of this study were to: (1) evaluate the psychometric properties of a French Canadian version of the Hospital Anxiety and Depression Scale (HADS-FC) in a large population of primary care patients in Quebec, Canada; (2) conduct a transcultural validation of the original HADS in a subsample of English-speaking patients; (3) explore HADS properties in subgroups with or without multimorbidity. ⋯ The HADS-FC and English HADS presented good psychometric properties in primary care patients, including patients with and without multimorbidity. However, its performance as a screening instrument in these settings with patients of varying clinical profiles requires more scrutiny.
