Many topics in women's health are multidisciplinary in nature. In addition to searching the PubMed database, you may find it helpful to search some specialized databases that provide good coverage of psychology, sociology, public policy, economics, public health, and education.
Your literature review must only use primary sources. Primary sources are hypothesis driven and contain original research data typically found in peer-reviewed journals. Such sources include original research articles, conference papers, dissertations, and technical papers. Secondary sources are derived from primary sources and help interpret, evaluate, or summarize original research. Secondary sources include textbooks, narrative review articles, systematic reviews, and meta-analyses, and should only be used to gain background information for your research.
