person who provides information to researchers about a phenomenon under study; a term used mostly in qualitative studies
Intervention Protocol
specification of what the intervention and alternative (control) treatment conditions are, how they should be administered and who should administer them
Literature Review
summary of research on a topic, often prepared to put a research problem in context or to summarize existing evidence; typically less rigorously conducted that a systematic review
