I
have been asked to write a literature review as an article in a journal for
midwives and doulas. I thought you might find it helpful to "look over my
shoulder" as I select a topic, do the literature search, and organize and
write the paper. Today, I will talk about the topic selection and literature
search, I'll save writing for a later time.
The journal
editor asked me to pick a topic on the subject of child obesity that would be
relevant to childbirth educators (e.g., midwives, and doulas). Let's start by
doing a search in the Walden library in Psycinfo, Cinahl (a nursing database)
and Medline. I like to start searches as narrow as I can; I want to link child
obesity closely to pregnancy – since that is the readers' interest - so I start
with the search term of infant obesity.
We find a variety of topics, many focused on interventions and assessments; we
read through the titles and abstracts. One topic that particularly appeals to
me is the relationship of maternal obesity to child/ infant obesity. Our next
step, is to make sure there is sufficient literature in this area to write a
literature review on the topic. Let's do a search using the terms maternal obesity and infant obesity, hmmm, only 3 articles.
Let's try the terms maternal obesity
and child obesity. There were a
number of articles on this, so let's narrow it further and add in the term review- which will find us any previous
literature reviews of the subject, and there are 3 recent ones.
Our
next step (at least my typical next step) is to go to Amazon.com and search for
any reference books on the subject. Let's search using maternal AND child obesity. There are a couple of books on the
topic, they have the tables of content available, so we double-check and yes,
there are chapters on the topic (I add the books to my Amazon wish list to save
them for now). I now know there is a reasonable literature available on the
topic. Now let's double check that the editor is interested in the topic. I
send her an email and yes, she likes the topic.
Now
we go back to the Walden library and extend the search to maternal obesity and long
term effect. I also run the searches again in the Psychology Sage database.
I download any articles that seem appropriate and save them on the computer, I
end up with 10 articles. We also go back to Amazon and buy the best two books
on the subject. I will probably need more articles when I start to write, but
this is enough to get me started and familiar with the topic area.
Now
I need to go read what we have found. How did the process we went through
relate to your dissertation searches? Ours was a smaller version of your
literature search. You can start with same basic search technique: 1) Discover
whether there is sufficient literature for your proposed topic. 2) Start very
narrow in the search and then broaden it. You will have specific variables that
you are interested in, so include those as you broaden the search. 3) Download
(or print) your articles and be sure to check if there are reference books
available on the topic. Walden's library has some ebooks available, but they
often are out of date and may not directly relate to your topic.
Next time, I will post an updated blog index. Do
you have an issue or a question that you would like me to discuss in a future
post? Would you like to be a guest writer? Send me your ideas!
