A dataset containing simulated responses from 5,000 patients on the PCL-5
(PTSD Checklist for DSM-5). Each patient rated 20 PTSD symptoms on a scale
from 0 to 4. The dataset additionally ships with three demographic columns
(patient_id, age, sex) so that the demographic
carry-through workflow (id_col) can be demonstrated end-to-end on
the bundled data.
