Epidemiology is driven by data and usually relies on the collection of information and the analysis and interpretation of that information. Researchers in epidemiology are interested in the constant measurement or assessment of the relationship between exposure and disease/outcome. The study designs can be classified as observational or experimental depending on the approach used to assess the association between exposure and outcome.
For the Unit III Case Study, research and describe one experimental study design and one observational study design, and provide at least one example of how each design can be used in a research intervention.
Explain how one of these studies can be applied to one of the health problems you identified in your community. Provide a statistical table of the health problem you identified in your community (prevalence, incidence, mortality rates, and morbidity rates). This information is usually found in the local departments of health websites. Explain whether the health problem in your community is an endemic, epidemic, or pandemic.
Your case study must be a minimum of three pages in length, excluding the title and reference pages. To support your ideas, use a minimum of three outside sources; one may be the textbook. Additionally, use a source that focuses on your community, such as a newspaper or journal article.
Remember that all written assignments must be formatted using APA style, including in-text citations and references.

What is APA Format and Why is it Used?
The American Psychological Association is a professional organization representing
psychologists in the United States. APA format is a set of rules developed to assist with writing
and the citing of sources. Following the rules laid out in the Publication Manual helps to
prevent plagiarism and acknowledges the original author of the information used. It is meant
to provide a concise and standardized citation format for written assignments (such as essays,
research papers, and article critiques, among others) and is used for all Columbia Southern
University courses.
In educational institutions, academic integrity is an area of great concern. Academic
integrity refers to being intellectually honest by “avoiding… cheating, plagiarism, self-
plagiarism, and/or poor scholarship” (Columbia Southern University, 2019, p.28). Adhering to
APA guidelines can prevent academic integrity violations (especially plagiarism) by clearly
marking which words and ideas belong to outside sources. Committing an academic integrity
violation of any kind can have serious consequences.
Plagiarism is the act of stealing someone else’s work and passing it off as one’s own. It
can be deliberate or accidental; deliberate plagiarism includes directly copying, summarizing, or
paraphrasing a source without giving credit to the author or putting it in quotation marks. This
type of plagiarism also includes turning in a paper that has been bought, written by another
student, or copied from another source. Accidental plagiarism is when a writer uses another
author’s thoughts or ideas without realizing credit must be provided. This includes working in
groups and submitting the same answers as other students, forgetting to place quotation marks
around a direct quotation, omitting an in-text citation for a summary or a paraphrase, and
omitting an in-text citation for the ideas of another writer. Accidental plagiarism also includes
submitting an assignment that has already been previously submitted in another course.
Unfortunately, both types of plagiarism can result in a failing grade, suspension from the
university, or even expulsion.
There are a few ways APA can help students avoid plagiarism. The primary way to avoid
it is to cite any ideas that are not one’s own. Citations help readers to locate the sources used in
a paper. Citations should not only be used for direct quotes, but they should also be provided
when information is paraphrased or summarized from another author. Paraphrasing a source’s
material is a good way to avoid copying directly from an outside source and possibly being
reprimanded. If any questions or concerns about APA format, please feel free to contact the
CSU Success Center by email at [email protected] or by phone at (877) 875-
0533.

Citing Sources
When writing a paper in APA 7th edition style, there are two specific ways to cite the
information that is used: within the text and in the reference list at the end of the paper. Citations are utilized when a phrase, a piece of specific information, or a sequence of sentences
is drawn from an outside source. To meet APA requirements specified for CSU written essay
responses, in-text citations and a reference list must be included if any outside sources are
used. For formal papers, follow all guidelines listed in this handout. For all rules and
requirements of APA, please refer to the 7th edition of the Publication Manual of the American
Psychological Association, which can be purchased through the American Psychological
Association at https://apastyle.apa.org/products/publication-manual-7th-edition/.
In-text Citations
• An in-text citation should be used when a phrase, a piece of specific information, or an
idea is drawn from an outside source.
• In-text citations are also required when putting the author’s information in your own
words (paraphrasing).
• Citing helps to prevent plagiarism, and it acknowledges the original author of the
information used. • In-text citations and reference citations must always correspond; each in-text citation
must have a matching reference citation and vice-versa. APA uses the author-year
method of citation.
• It is standard practice for the period at the end of the sentence to be placed after the
last parentheses of the in-text citation. An exception is made if inserting a direct quote
that contains more than 40 words; in this instance, the period is placed directly before
the in-text citation.
Paraphrased Information
When paraphrasing or summarizing a source, provide the author’s last name and year of
publication (separated by a comma). Page and paragraph numbers are not required when you
are paraphrasing information. However, be sure to consult with your faculty member to
determine his or her preference on adding page numbers in citations.
Direct Quotations If utilizing a direct quote, this must be indicated by placing the passage in quotation marks.
Further, the specific page or paragraph number is always required. If there is no page or
paragraph number, as is the case for many electronic sources, provide a section heading or
other label to indicate the passage the quote was borrowed from.

Direct Quotations of 40 or more words
Block quotations (quotes that contain 40 words or more) are formatted differently, as they
have no quotation marks. In formal writing, block quotations are acceptable, although their use
should not be in excess. While block quotes are accepted in formal writing, the use of them in
essay responses is not encouraged due to the length of the assignment. Block quotations are
indented an additional .5” and double spaced. The period is placed before the citation.
Block Quotation Example
The solutions proposed by a number of advocacy groups underscore this interest in
political and cultural change. A report outlined trends that may have contributed to the
childhood obesity crisis.
This includes food advertising for children as well as a reduction in physical
education classes and after-school athletic programs, an increase in the availability
of sodas and snacks in public schools, the growth in the number of fast-food outlets,
and the increasing number of highly processed high-calorie and high-fat grocery
products. (Kaiser, 2004, pp. 1-2)
Reference List
The reference list is of the utmost importance, as it allows the reader to access the sources cited in the in-text and enables the student writer to give credit where credit is due. For this
reason, the references should contain accurate information, as well as proper punctuation and
spelling. References will follow the conclusion of any APA document. For each reference listed,
there will be at least one corresponding in-text citation in the document. Examples of reference
source formatting can be found on the following pages.
• If there is a digital object identifier (DOI) available, include that in the reference. The DOI
is precisely used to give the reader information about where the document can be
found on the Internet. The DOI is typically located near the copyright notice on the first page of the electronic journal article. In the case that there is no DOI, provide the
homepage URL of the web page where you found the article. (Please note the DOI,
when available, is required in doctoral courses.)
• Multiple citations containing the same author and year should first be listed
chronologically by the specific date (with newer sources being listed first) and then
alphabetically by the title. A lowercase a, b, c, etc. should be placed after the year to distinguish between the entries. This is also used in the in-text citations. For example:
Smith, J. (2013a, March 8). How to groom cats. Garden Press.
Smith, J. (2013b, January 20). How to groom dogs. Garden Press.

General

Information
• When listing the author on the reference list, the
last name should be first, followed by the
author’s first and middle (if applicable) initials.
For example: Smith, J. R.
• References should be placed in alphabetical order
by the first author’s last name, by associates (if
the work is authorized by an organization), or by
anonymous. Anonymous should only be listed as
the author if it is signed as such.
• If a particular person did not create the document
being cited, use the organization that created the
document.
• The document title can be substituted as the
author if no author is provided. In this case, the
first word of the title will dictate the alphabetical
placement (“a,” “an,” and “the” notwithstanding).
• The letters “n.d.” (no date) can be utilized if the
source listed has no listed date. Substitute “n.d.”
where the date would normally go.
For example: Smith, R. T. (n.d.)…
• Professional credentials, such as Ph. D., should
not be used on the reference page.
• References beginning with numerals should be
alphabetized based on the spelling of the numeral
• States should be identified with their two letter
abbreviations, such as AL, MS, and NY.
• Spell out cities and countries outside the United
States.
