4550- Evidence Based Nursing

Nursing Students Ohio University

Published

From looking at the classes starting in fall, I'm guessing that Evidence Based nursing is replacing Research? Anyone have any idea if stats is still required prior to taking this, as it was with Research?

Decide whether this study was an experimental design or a quasi-experimental design and list three reasons to support your decision

Am I the only one picking neither here???

Nope...it's neither.

email just recieved from Professor A. My question to her was about leaving off the meta analysis part of the assignment, since TA said to leave it in.

Her response was short

" Yes - just these instructions with the characteristics article.

MAA"

So, as far as I am concerned, that is right from the horses mouth. I spent at least 5 hours looking for an article and starting to try to understand it, but I am relieved it is not .... just got to complete DB assigment.

Nope...it's neither.

Hummmm....have to disagree. Pretty tricky.

Really? No control group, no intervention that I can find. Nothing offered to one group that wasn't to another. Guess I am dense but I do not see experimental or quasi-experimental in this.

Who knew that a single DB posting would cause so much chaos?

I had to Google to find clearer examples of the differences between experimental design and quasi-experimental design. I just find the textbook does not explain it well enough for me. Once I got some examples, it was very clear to me then. I have to do that on occasion anyways; it just helps me to read another explanation on something that I can't seem to grasp well.

A control group is not always necessary for a quasi-experimental design. Here is one definition that I found that may be helpful:
Quasi-experimental studies take on many forms, but may best be defined as lacking key components of a true experiment. While a true experiment includes (1) pre-post test design, (2) a treatment groupand a control group, and (3) random assignment of study participants, quasi-experimental studies lack one or more of these design elements.
So the lack of a control group does not necessarily rule out this being a quasi-experimental study. While I frankly do not understand the statistical tests that were done, it is clear that there are a number of independent variables (listed on p 32) and dependent variables (listed as outcome variables on the same page). What I really don't understand is how, as a researcher, you can have an accurate study with so many moving parts, i. e., multiple DV's and IV's. One of the keys to either experimental or quasi-experimental designs is that there has to be an association between IV and DV and that relationship must be causal. More importantly, the relationship between the IV and DV must not be explainable by other variables. It's hard to see in this study that these tests are met.

But hey, what do I know? I got a 77 on the last quiz.

Well - you explain it better than the book does! My head has done nothing but spin with these last 4 chapters. Thought I had a pretty good handle on things until this module. Counting down until done with this class .... :confused:

Chuckster sounds like you have you DB post with what I just read, minus the references lol. Great description, thanks

Very good explanation. And since we have 2 choices we better choose one! I never considered these to fit either criteria. I don't know about you guys but I can't afford to lose ANY points on these $%#* DB posts!!! Please let it end!!!

HELP PLEASE! Last week I retrieved an article from the OU library...a first! I did not put "retrieved from" so lost a point...so sad. Anyhow, I found another article but I don't know how to note where I retrieved it. The URL simply takes you to the OU Library. What to do??? How are you guys doing this? I went to Google and tried to find it so I could "retreive" it but alas, only found an abstract. This is so frustrating. Thanks in advance all you smart APA experts!
