The survey was administrated by Metro Media Transilvania in the period April –June 2016 by the CATI method (Computer Assisted Telephonic Interview). The volume of the sample was 1707 individuals which confers it representativeness and reliability.

The questionnaire draw up by the project team was pre-tested also by MMT in order to estimate the non-response ratio. Concerning the methodology of constructing the questionnaire we mention that it contains objective items (binary items with a dual form of response yes/no) as well as subjective items (the respondent can use a Likert scale from 1 to 5 or can respond freely).

The corrected database, with all the questions from the questionnaire and all the coded variables and their values was delivered to the project team in the month of June 2016, facilitating the continuation of the research.
