Resumo
Background: Despite the focus on facial photoaging ratings, there are few classifications developed for forearm skin aging assessment.Objective: To develop and validate a clinical scale for the evaluation of forearm skin aging.Methods: Three clinical dermatology faculty members selected, discussed, and appraised the main signs of forearm photoaging. The validation of the resulting scale was performed by 5 assessors who were previously trained to classify 102 photographs of forearms with different degrees of aging. Retests were performed in 15 days.Results: There was significant correlation between the selected variables and the subjective global aging scale. The developed scale showed high internal consistency (Cronbach's alpha = 0.87) and high correlation with the global photoaging scale (rho = 0.92). Inter- and intraobserver final scores showed high agreement.Conclusion: A validated clinical photoaging scale for forearms with internal consistency, reliability, and validity was developed.
