Alopecia Areata–Specific Patient-Reported Outcome Measures

This systematic review evaluated the quality of 11 alopecia areata–specific patient-reported outcome measures (PROMs) and found that older PROMs suffer from poor development design when assessed with contemporary standards. The Alopecia Areata Patient Priority Outcome (AAPPO) was the only PROM with high-quality evidence of sufficient structural validity and internal consistency, and it was also the only one assessed for test-retest reliability. Despite some PROMs showing sufficient content validity and internal consistency, there is a significant lack of high-quality validation data for the internal structure of these measures. The study emphasizes the need for further validation studies to improve the rigor and quality of AA-specific PROMs.
