Procedure
Initially, we contacted the blog’s author (María José Moya Villén)
to explain the objectives of the project and to request permission to
invite participants into the research program via her blog. Once she
agreed, she posted a link to the questionnaire on the blog home page
“Mi Estrella de Mar” [My Sea Star]. The call for participation was
posted across different groups in the social network, including
Facebook, the websites of the “Asociación Alicantina para el Estudio
de las Intolerancias Alimentarias y Ambientales” [Alicante Association
for the Study of Intolerance in Food and Environment] (http://aaeiaa.
wordpress.com/), and “Todoalergias” [AllAllergies] (http://www.
todoalergias.com/).
Diffusion was made via a pdf document, which provided
information concerning the research (aim, questionnaires) and the
principal investigator (profession, workplace). Individuals who
agreed to participate were linked into the survey and the data sent
automatically to the principal investigator. All data were codified to
ensure anonymity
