Q: What methods and procedures can we use if we are not allowed to issue questionnaires and conduct interviews?

Thank you for your question. There are several different data collection methods that researchers have at their disposal. Selection of an appropriate data collection tool will depend on what you're studying and therefore what type of data you require. Based on your question, we assume you're looking for qualitative data from human participants. If interviews cannot be conducted and questionnaires cannot be issued, other options are observation (observing participants in the required environment), focus groups (gathering the participants in small groups with a moderator to discuss specific topics), and online forums (discussion of topics on a broad forum and collection of data from comments/opinions posted by participants). Web or mobile surveys are other suitable methods (assuming that you can't distribute physical copies of questionnaires but can do so through other media).
