Validation of a Patient Knowledge Questionnaire for Pulmonary Hypertension

Participants will complete one version of the DICTA questionnaire, developed to assess patient knowledge about pulmonary arterial hypertension. Depending on the study phase, participants will contribute to content validation (expert judges), semantic validation (patients), or psychometric validation (patients). In the final phase, additional data including risk stratification (COMPERA 2.0), hospitalizations, and quality of life scores (CAMPHOR, SF-36, MBG) will be collected for correlational analysis.
