Welcome to the discussion on sampling methods!
You may begin posting on Sunday, January 27th, 2019 for credit.
The course outcomes for this week include:
1. Examine the sources of knowledge that contribute to professional nursing
practice.
2. Apply research principles to the interpretation of the content of published research
studies.
3. Identify ethical issues common to research involving human subjects.
Choosing an incorrect sampling strategy could have devastating effects on a
research study. This discussion should help you to recognize various sampling
strategies encompassing r&om & non-probability methods & the effect they could
have on research study results or the application of those results.
Please utilize the Threaded Discussion graded rubric as a guideline for
posting to the discussions. These are the criteria you will be graded on which
includes the use of citations & references according to current APA.
As always, please be sure to ask any questions you have in the Q&A forum.

Hello Prof. Hobbs & Class,
Sampling is defined by Merriam-Webster’s dictionary as “the act, process, or
technique of selecting a representative part of a population for the purpose of
determining parameters or characteristics of the whole population”(n.d.) (Emerson,
2015).
What is convenience sampling? In chapter 7 in our textbook it says, “Convenience
sampling is a non-probability method that includes subjects who are available
conveniently to the researcher” (Houser, 2018). In other words researchers will find
the participants that fit their sampling needs & then ask those same participants to
find friends or others like themselves to add to the sample & make the numbers
good/big enough for the researcher.
Some of the strengths of using a convenience sampling are that is easy to find
subjects since it is conducted with same type of subjects & they is less expensive to
conduct. On the other h&, using convenience sampling can introduce bias into a
sample & the sample is not representative of the entire population making it weak
sampling.

Enajite,
Thank you for initiating this week's discussion!
Bias is definitely one limitation to a convenience sample, as you mentioned. Can you
give me an example of how using a convenience sample in a healthcare setting
could be detrimental?

Hello Prof. Hobbs,
An example would be; Nurses screen & evaluate inpatients & outpatients for family
violence (FV) during the hospital admission process. A literature review was
conducted for 2009 to 2016 in EBSCOhost, PubMed, & Cochrane library databases
using the search terms of domestic violence screening; barriers & domestic violence;
domestic violence, healthcare, & nurses' attitudes; & domestic violence & nurses'
knowledge. The purpose was to evaluate nurse perceptions & attitudes about
current FV patient screening processes. The study was conducted in the ED &
inpatient & outpatient settings in a rural healthcare system with three hospitals.
Nurses performing FV screening during admission completed a 36-item validated
survey; nurses previously completing the hospital's online FV education module also
evaluated the module. In this study, most of the 128 participating nurses (60.9%)
had not identified any patients as positive for FV in the last year (average, 1.8); of
those identifying FV-positive patients, the annual average was 2.9. Nurses perceived
screening questions allowed FV-positive patients to be identified. Qualitative
analysis identified the need for patient privacy during the screening process & for
additional FV education & training for nurses. Because this research was conducted
in a rural healthcare system, the results may not be generalizable to other settings.
The research involved a self-selected convenience sample of nurses. In
Conclusion Nurse administrators should evaluate best practices for privacy for FV
screening & assess & provide FV-related education & training for nurses.

Bravo, Enajite! This is a great example of how a convenience sample can be limiting
& not generalizable. I suspect that one of the implications for future research would
be to repeat the study in a more representative setting.

Hello Enajite,


I thought that your post had great insight. I do agree that convenience sampling is
very biased, but sometimes given the nature of the study & the amount of capital
available, it is the level of research that can be done at the time. So, I do underst&
why criticisms can follow because the demographics under observation are not fully
represented. Although they are subject to scrutiny, convenience sampling can be
used as a stepping stone in an initial study & then progress the researcher to using a
more detailed sampling methodology like a Systematic Sampling Method. According
to Haegele & Hodge, “Researchers prefer r&om samples or systematic samples
because of the high likelihood of representing the population accurately. However, it
is not always possible to obtain a r&om or systematic sample of participants. In
cases like this, researchers may recruit a convenience sample. Convenience
sampling is selecting a group of individuals based on them being available for the
study (Fraenkel et al., 2012)” (Haegele & Hodge, 2015).
