Background:
The Women's Androgenetic Alopecia Quality of Life (WAA-QoL) questionnaire is the only available specific instrument to evaluate QoL in female pattern hair loss (FPHL) patients. It is made of 16 questions with 6 alternatives, is self-administered, and has not yet been adapted or validated to Spanish.
Objectives:
The objective of the study was to translate into Spanish, culturally adapt, and validate the WAA-QoL questionnaire.
Methods:
The translated version (WAA-QoL-sp) was submitted to 453 general population women by e-mail after authorization by the author, translation, and adaptation to Spanish of the WAA-QoL questionnaire.
Results:
A total of 453 women were evaluated; the median age was 39 years, and there was high internal consistency: Cronbach's alpha was 0.969 for the WAA-QoL-sp.
Study Limitations:
Sampling of subjects was from diverse Spanish-speaking countries (such as Mexico, Colombia, Chile, Venezuela, Cuba, and Spain) but not from all Spanish-speaking countries.
Conclusions:
A Spanish version of the WAA-QoL questionnaire was translated and adapted, which proved to be consistent and a valid tool for assessment of FPHL.
