Translation to Portuguese and cultural adaptation of Food Allergy Quality of Life Questionnaire Parent Form (FAQLQ PF)
Food allergy is a health problem with significant negative impact in Quality of Life (QoL) We aimed to translate into Portuguese and culturally adapt to our population the Food Allergy Quality of Life Questionnaire Parent Form (FAQLQ PF) Cross cultural translation was performed according to guidelines. Linguistic validation consisted in 3 steps: forward translation, backward translation and comprehensibility testing. A consensual version was obtained and tested in parents of food allergic children by cognitive debriefing. Twelve questionnaires were fulfilled, all completed in 15 min. No comments, doubts or suggestions were posed, except for 2 parents regarding a question about the number of food their children had to avoid. Two gave special positive feedback about the utility of FAQLQ PF. Changes have been included after this pre test in accordance to doubts and suggestions of participants, and the Portuguese version is now able to be used in clinics and research.
