Validity and Reliability of a Rosacea Self-Assessment Tool

This article discusses a valid and reliable rosacea severity self-assessment tool (RSAT) to measure rosacea severity. To determine test –retest validity, participants completed the self-assessment twice. A blinded physician graded the participant’s disease severity with the Investigator Global Severity (IGS) score. Pearson correlations were used to assess the relationship between the self-assessment measure and the IGS. Test–r etest RSAT measurements were correlated. The RSAT represents a valid and reliable tool. This tool may facilitate determination of rosacea severity in survey research studies.
