Validity of the Parsley Symptom Index-an Electronic Patient-Reported Outcomes Measure Designed for Telehealth: Prospective Cohort Study.

The PSI demonstrates convergent validity with the SRH for adults with chronic disease in a telehealth setting. This finding further supports the validation of the PSI in a real-world clinical setting. Although it is conceptually similar to the 1-question SRH, the PSI is a 45-item PROM designed to capture quality of life and specific symptoms by body system. Future studies will compare the PSI to multi-item PROMs.
