This is one of my favorites! In 8 minutes you’ll be able to explain what scientific evidence is considered the strongest and why!

How to use this info? After you gather literature on a topic, use this information to organize it from strongest evidence to the weakest. Then write your review of literature starting with the strongest first!
Below is a YouTube recording of this week’s presentation from the Midwest Nursing History Research Center. The author presents an overview of her book and where you can learn more.
According to the Oral History Association:
Oral history is a field of study and a method of gathering, preserving and interpreting the voices and memories of people, communities, and participants in past events. Oral history is both the oldest type of historical inquiry, predating the written word, and one of the most modern, initiated with tape recorders in the 1940s and now using 21st-century digital technologies.
In Doing Oral History, Donald Ritchie explains, “Oral History collects memories and personal commentaries of historical significance through recorded interviews. An oral history interview generally consists of a well-prepared interviewer questioning an interviewee and recording their exchange in audio or video format. Recordings of the interview are transcribed, summarized, or indexed and then placed in a library or archives. These interviews may be used for research or excerpted in a publication, radio or video documentary, museum exhibition, dramatization or other form of public presentation. Recordings, transcripts, catalogs, photographs and related documentary materials can also be posted on the Internet.“ Oral history does not include random taping, such as President Richard Nixon’s surreptitious recording of his White House conversations, nor does it refer to recorded speeches, wiretapping, personal diaries on tape, or other sound recordings that lack the dialogue between interviewer and interviewee.”
For thought: Whom within your circle could contribute to our healthcare history? What a wonderful contribution if you could collect their oral history using resources from the Oral History Association and elsewhere!!
REMEMBER:
Research design = overall plan for a study.
The 2 major categories of research study design are:
- Non-experimental, observation-only studies, &
- Experimental testing of an intervention studies.
Correlation study designs are in that first category. Correlation studies focus on whether changes in at least one variable are statistically related to changes in another. In other words, do two or more variables change at the same time.
Such studies do not test whether one variable causes change in the other. Instead they are analogous to the chicken-and-egg dilemma in which one can confirm that the number of chickens and eggs are related to each other, but no one can say which came first or which caused the other. Correlation study questions may take this form, “Is there a relationship between changes in [variable x] and changes in [variable y]?” while a correlation hypothesis might be a prediction that, “As [variable x] increases, [variable y] decreases.”
An example of a question appropriate to this design is, “Are nurses’ age and educational levels related to their professional quality of life?” Sometimes a yet-unidentified, mediating variable may be creating the changes in one or all correlated variables. For example, rising nurse age and education may make them likely to choose certain work settings with high professional quality of life; this means the mediating variable of work setting—not age or education—might be creating a particular professional quality of life.
| Alert! Correlation is not causation. |

Field medicine= healthcare in the non-hospital context when higher level technical care is not available.
“History provides current nurses with the same intellectual and political tools that determined nursing pioneers applied to shape nursing values and beliefs to the social context of their times. Nursing history is not an ornament to be displayed on anniversary days, nor does it consist of only happy stories to be recalled and retold on special occasions. Nursing history is a vivid testimony, meant to incite, instruct, and inspire today’s nurses as they bravely tread the winding path of a reinvented health care system.” (American Association for History of Nursing)
