Why This Matters for Nursing: Evidence-based practice requires evaluating sources. A peer-reviewed research article (primary) carries more weight than a magazine summary (secondary). Knowing the difference helps you find the most reliable information for patient care.
| Source Type | Definition | Examples |
|---|---|---|
| Primary | Original material from the researcher, participant, or direct observer; often created during the event but not necessarily. May include the creator's own interpretation, but not another author's later synthesis | Research studies, original data, interviews, speeches, diaries |
| Secondary | Another author's later analysis, interpretation, or synthesis of primary sources | Textbooks, review articles, news reports, encyclopedias |
Ask: "How close is this to the original event/research?"
