Piloting. The extended version of the AEBQ was piloted online in an opportunity sample of 49 adults (21e73 years old), 36 women (79.6%) and 13 men (20.4%). Colleagues at University College London were asked to circulate a link to the questionnaire to their friends and family from a range of professional backgrounds. Participants were invited to comment on each individual item and on the question- naire as a whole. Piloting led to changes in the response options from ‘never’, ‘rarely’, ‘sometimes’, ‘often’ and ‘always’, to ‘strongly disagree’, ‘disagree’, ‘neither agree not disagree’, ‘agree’ and ‘strongly agree’ because participants commented that the original response options did not fit with the questions. The new response options were tested with a small convenience sample (two females and three males, aged 31 ± 7 years). This answer format appeared to be more meaningful and better understood by this sample.Piloting also led to the deletion of the item “Given the choice, I would always have food in my mouth” because several participants commented that it “sounded a bit odd” or was “over the top”. A second item (“I am interested in food”) was eliminated because participants reported they found the meaning ambiguous. The remaining 47 item version of the AEBQ was included in the Prin- cipal Component Analysis (PCA).
