Is this trial a fit for you?
✓Likely a good fit
Adults aged 18 or older, fluent in French, who are outpatient or hospitalized for any reason and willing to participate are the intended participants.
✕Probably not a fit
People who cannot read or understand French well, are under legal protection, have significant cognitive or hearing impairments, or otherwise cannot complete questionnaires are unlikely to benefit from participation.

What this trial studies
This observational study will enroll about 90 French-speaking adults at Hôpital Avicenne to complete the PHQ-4 and PC‑PTSD‑5 alongside established gold-standard measures (PHQ‑9, GAD‑7, PCL‑5). Convergent validity will be examined using Pearson correlations between the short screens and their corresponding longer instruments, with comparisons across inclusion centers. Secondary analyses include exploratory factor analysis, internal consistency (Cronbach's alpha), and test–retest reliability (intraclass correlation) in a subsample of at least 20 participants, plus descriptive statistics of sociodemographic and clinical variables. The target sample size (≈90) was chosen to exceed the 10-per-item rule for both scales while allowing for loss to follow-up and adequate statistical power.
Why it matters
Potential benefit: If successful, clinicians will have brief, validated French tools to more easily detect anxiety, depression, and PTSD, enabling earlier care and referral.
How similar studies have gone: The PHQ‑4 and PC‑PTSD‑5 are well validated in English-language primary care populations, and translating/validating established screens into other languages is a common, generally successful approach.
