ABSTRACT
Connecting the literature to the study involves two tasks, and researchers are likely to jump back and forth between them as they learn more from the literature and develop a more targeted research question. The first task is to come up with an outline of topics that the literature review should include. Depending on the length of the article, these may form the headings and subheadings in the final literature review. The second task is to scrutinize elements of the research question and the research plan that is taking shape. Good literature reviews do not go over articles one at a time. Instead, they group the literature together by topic. If there are two types of prevention strategies that are common, and the current research only deals with one, it is worth noting that there are two types, but the literature review need not discuss research on the second strategy in any depth.
