    •  Evidence is based on research Research undergoes peer review Research is published in scholarly journals
    •  A process done by many scholarly journals when considering the publication of research articles Expert reviewers (peers) evaluate the article’s methodology, merit, and overall unique contribution to research in a specific discipline PRIOR to publication In the health sciences, peer review is almost universal when it comes to primary research published in the journal literature Why is this important?
    •  Written for researchers & scholars in a field Primary purpose is to disseminate research results May also contain:  Editorials, Job announcements, book reviews Follow a regular and recurrent publication pattern (weekly, monthly, quarterly, etc)
    •  Journal of the Academy of Nutrition and Dietetics American Journal of Clinical Nutrition Journal of the American College of Nutrition Journal of Nutrition
    •  Present the findings/results of a research study The authors of the article are the persons who conducted the research-i.e primary The article will include: why, how, what Typically published in scholarly journals & undergo peer review An example
    •  Besides research, you may also find the following in peer review journals: News articles Letters Editorials Book reviews Job announcements Obituaries of prominent members of the field ****However none of these are peer reviewed****
    •  Magazine and newspaper articles are not considered scholarly  They are not peer reviewed  If they report on research, it is research done by others (i.e. secondary)  Example

    •  Specialized search engines that find magazine, newspaper, and journal articles Some are multi-subject and others focus on a specific discipline For nutrition, the mostly common used are Medline and CINAHL
    •  Cumulative Index to Nursing and Allied Health Contains articles in nursing and fields such as nutrition, audiology, physical therapy, respiratory therapy, etc 750 journals 1 million citations back to 1937
    •  World’s premier medical/health science database Articles from all health fields: medicine, nursing, dentistry, exercise science, veterinary medicine, allied health, etc. 4800 journals Over 19 million citations back to 1940
    •  We now have a “meta” search engine that searches CINAHL, Medline and our other databases at once. It is on the library homepage and it’s called the “search all” box
