This upload contains the full technical documentation and a free evaluation sample (500 veterans, 2,500 assessment rows) — not the full dataset. The complete dataset — 30,000 veterans, 150,000 assessment rows over 24 months, plus OMOP CDM v5.4 tables — is available at: https://sentineldata.com.ua/dataset/combat-ptsd-veteran-mental-health-cohort Sample contents: cmho_population_wide_SAMPLE500.parquet 500 rows × 50 columns cmho_longitudinal_SAMPLE500.parquet 2,500 rows × 13 columns CMHO_Sample_Passport_EN.pdf sample passport (inside the archive) The sample is the first 500 veterans by ID (CMHO-000001–CMHO-000500) and all of their longitudinal rows — a true subset, byte-identical to the corresponding rows of the full dataset.

The OMOP CDM tables are included only in the complete dataset. Fully synthetic. Contains no real patient data.
