Résumé	The Patient Health Questionnaire-9 (PHQ-9) is a brief, 9-item self-report instrument for screening and measuring the severity of depressive symptoms in primary care and mental health settings. Developed by Kurt Kroenke and colleagues in 2001, the PHQ-9 is now widely used in healthcare systems worldwide as a rapid, accurate screening and monitoring tool.	The Generalized Anxiety Disorder-7 (GAD-7) is a brief, 7-item self-report instrument for screening and assessing the severity of anxiety symptoms in primary care and mental health settings. Developed by Spitzer and colleagues in 2006, the GAD-7 mirrors the structure and validation approach of the widely successful PHQ-9 depression screen and has rapidly become a standard anxiety assessment tool.
