Would this kind of paraphrasing be called "plagiarism"?
Assuming that (Gedik, 2010) is the source of the original, I don't think you have a problem since, (a) you give the citation and (b) the ways to express the needed ideas here are very limited.
You are clearly making reference to the original work. And it is clear you are describing the work of another.
The essential elements describing the questionnaire must all be present and you have minimally done that.
