Objective: Determination of the clinical significance and validity of the most common dermatological indices for assessing acne severity.
Materials and methods: The results of a clinical examination of 230 acne patients (129 men and 101 women) were analyzed, resulting in the recording of data according to the GAGS, IGA/PGA, DIA, and ECCA.
Results: Interpretation and statistical processing of the obtained data revealed no agreement among the indicators of any of the scales, and the reliability of these indices revealed extremely low validity thresholds.
Conclusion: These data indicate the need to develop a fundamentally new and easy-to-use acne severity assessment system.
