Primary Research or "original research" means that the authors of an article or report are the same people who conducted the research and gathered the data discussed in that article/report. In other words, to be Primary Research, authors must be writing about their own original research.
Examples of Primary Sources/Primary Research include: randomized control trials, cohort studies, and case control studies.
Secondary Sources/Secondary Research occurs when authors are collecting, analyzing, and discussing existing research and data (research studies conducted by others). NOTE: Most journal articles include a Background section or brief review of previous research done on the topic- this does not mean that article cannot be primary research. You will need to identify the type of study it is and/or look at the Methods/Methodology and Results sections to determine if an article is primary or secondary.
Examples of Secondary Sources/Secondary Research include: systematic reviews, meta-analyses, and clinical practice guidelines.

A review of the abstract and text of an article will provide important information of assistance in identifying it as a research study.
Look for the headings like the following:
It is important to be able to distinguish whether the author is reporting on the findings of his or her study (primary/original research).
If the author of the article is only conducting a literature review of other studies, or the article is a systematic review or meta-analysis, this is not a primary research study.
Scholarly Resources are generally written for an academic audience by experts in a specific subject discipline.
IMPORTANT: **Usually when an instructor says you need scholarly sources, they mean peer-reviewed articles.**
Examples of Scholarly Resources include: Academic/peer-reviewed journal articles (most common), books written by experts in a field, and formally published encyclopedias and dictionaries.
Peer Reviewed Journals & Articles are evaluated by multiple experts in a journal’s subject discipline prior to publication. The peer-review process ensures that the articles published within peer-reviewed journals are academically rigorous and meet the required expectations of an article in that subject discipline.

You can find evidence for clinical decision making in quantitative and qualitative research studies. Mixed methods research studies use a combination of quantitative and qualitative methods and data.
Quantitative research refers to any research based on something that can be accurately and precisely measured and will include studies that have numerical data. Quantitative data are expressed numerically and analyzed statistically. The data are collected from experiments and tests, metrics, databases, and surveys. In healthcare research they often include studies of intervention effectiveness, satisfaction with care, the incidence, prevalence, and etiology of diseases, and the properties of measurement tools.
Findings in qualitative studies are not based on measurable statistics. Qualitative data are descriptive rather than numerical. Qualitative research derives data from observation, interviews, verbal interactions, or textual analyses and focuses on the meanings and interpretations of the participants. Qualitative research studies in healthcare investigate the impact of illnesses and interventions. The research explores experiences, attitudes, beliefs, and perspectives of patients, caregivers, and clinicians. The analysis of qualitative research is interpretative, subjective, and impressionistic.

A primary source is a description of a research study written by the original investigator(s).
Primary Research or "original research" means that the authors of an article or report are the same people who conducted the research and gathered the data discussed in that article/report. In other words, to be Primary Research, authors must be writing about their own original research.
Examples of Primary Sources / Primary Research include: randomized control trials, cohort studies, and case control studies.
A secondary source is a summary or description of a research study written by someone other than the study investigator(s).
Secondary Sources / Secondary Research occurs when authors are collecting, analyzing, and discussing existing research and data (research studies conducted by others). NOTE: Most journal articles include a Background section or brief review of previous research done on the topic- this does not mean that article cannot be primary research.

Journal- The title of the publication in which articles are published. Journals cover a specific subject, which can be either broad or narrow in scope. Professional, or trade, publications are a type of journal. For example, PC World.
Volume- Journals are divided into volumes and issues, which describe when articles in a journal were published. Most of the time, the volume number represents all issues of a journal published in a specific year. For example, all articles published in PC World in 2018 are Volume 36.
Issue- The issue number refers to each published installment of the journal. Most journals are published weekly, monthly, or quarterly. For example, if a journal is published monthly, each issue number represents a different month, with January being Issue 1. For PC World in 2018, in Volume 36, there are 12 issues.
Article- Each issue contains several articles. Each article is written by a different person, or group of people, on a specific topic, with its own title. For example, "How to Upgrade your Laptop's RAM" was an article published in PC World, Volume 36, Issue 7, on pages 84-89.
