The questionnaire asked participants to rate their agreement with statements in order to calculate their Facebook activity (such as «I'm posting photographs»), social comparison orientation («I often compare how I am doing
socially»), materialism («My life would be better if I owned certain things I don't have»), objectification of Facebook friends («Having many Facebook friends contributes more success in my personal and professional life») and instrumentalization of Facebook friends («To what extent do you think Facebook friends are
useful in order to attain your
goals?»).
