NUR 202: Research and Ethics: Types of Sources

Types of Sources

There are many kinds of articles published in nursing and other health fields. The information on this page provides a list of the main types of publications, along with sample sources. Use these samples to decode the kind of source you have. I've also included a discussion of primary and secondary sources in Nursing. You can also email me (Julie) with any questions.

Primary Sources in Nursing

Primary sources in Nursing report directly on the results of a study, clinical trial, or experiment. These sources tend to be written by the researcher who conducted the study.

Examples include:

  • pilot/prospective studies
  • dissertations or theses
  • cohort studies
  • survey research
  • lab notebooks
  • patient intervews
  • case studies
  • qualitative studies
  • clinical trials and  randomized clinical trials/RCTs
  • double blind method

Secondary Sources in Nursing

Secondary sources in Nursing summarize, evaluate or comment on primary source studies. Secondary source authors discuss work done by others.

Examples include:

  • reviews of literature, systematic reviews, meta-analysis
  • newsletters and professional news sources
  • clinical practice guidelines & standards
  • clinical care notes
  • qualitative synthesis
  • patient education material
  • government & legal material 
  • entries in nursing or medical encyclopedias or other books
