Validation of French PHQ-4 and PC-PTSD-5 Screening Scales

Sponsor: Assistance Publique - Hôpitaux de Paris

Summary

Mental illness is a major public health issue. It affects one in five people, represents the largest expense for health insurance (14%), is the leading cause of years lived with disability, and suicide is the main cause of death among people aged 15 to 35. Depression affects 15 to 20% of individuals at some point in their lives. Trauma-related disorders affect 4.6% of people, including 1- 2% with post-traumatic stress disorder (PTSD). Screening for mental health problems in primary care is crucial. It enables doctors to provide early treatment, reduces the need for emergency care, and decreases both the number and duration of hospital stays. However, general practitioners and other non-mental health professionals often report lacking the time, training, and tools to conduct such screenings. Fortunately, brief and validated screening tools exist in English: The PHQ-4 (Patient Health Questionnaire-4) for anxiety and depression, and the PC-PTSD-5 (Primary Care PTSD Screen for DSM-5) for PTSD. So far, no French versions of these tools have been validated.
