ABSTRACT
Abstract: Background: Female pattern hair loss (FPHL) is a common complaint in adult women and inflicts major impact in quality of life, however, there is no specific questionnaire available in Portuguese for such evaluation. Objectives: Translation into Brazilian Portuguese, cultural adaptation and validation of the WAA-QoL (Women's Androgenetic Alopecia Quality of Life Questionnaire). Methods: Methodological study. After authorization by the author, cultural (linguistic) translation and adaptation to Portuguese of the WAA-QoL questionnaire were carried out. The translated version (WAA-QoL-BP) and DLQI (Dermatology Life Quality index) were submitted to patients with FPHL for concurrent validation. Twenty patients were reevaluated to assess temporal stability. Results: A total of 116 patients with APF were evaluated, the mean age (SD) was 47 (14) years, and 89 (76%) patients were classified as grades II and III (Sinclair). There was high internal consistency: Cronbach´s alpha was 0.97 for the WAA-QoL-BP and 0.87 for the DLQI. The correlation between WAA-QoL and DLQI resulted in (rho) 0.81 (p <0.01). The intraclass correlation coefficient for complete agreement of WAA-QoL-BP was 0.95 (p <0.01) in the test-retest comparison. Study Limitations: Sampling of patients only from the State of São Paulo. Conclusions: A Brazilian version for WAA-QoL was translated and adapted, which proved to be valid and consistent.
