Can a research article topic formulate as a question? How does it impact to the acceptance of the article in a indexed journal ? Below is an example for such topic.
E.g., Does Social Media Influence Consumer Decisions?
Absolutely, why not! It will completely depend on how you / authors present / argue in the paper with questions / hypotheses / statements.
There are many ways to formulate / present the research paper -- (a) questions "The key research question is Which elements can visually capture the essence of a viral event?" [1], (b) statements / hypotheses "Users learn more effectively when training materials are presented after they fall for a phishing attack (embedded) than when the training materials are sent by email (non-embedded)." Both of these papers are published papers.
I believe that is no problem at all.Inspite I dont read research paper that the title formulated as a question.what I know is the title transferred to research question.
Yes there is no problem in it. It depends on the nature of research, as if it is related to a particular question then that may also be the title to give readers a direct understanding of the research work.
