The PAH-SYMPACT questionnaire is a newly developed patient-reported outcome instrument that demonstrates concept validity for assessing symptoms and impacts in PAH patients.
The PAH-SYMPACT® was shown to capture symptoms and their impacts relevant to PAH patients, demonstrating content saturation, concept validity, and ePRO usability. Final content and psychometric validation of the instrument will be based on the results of an ongoing Phase IIIb clinical trial in PAH patients.
