RES500

 

1A.Newton, Bower, and Williams (2004) outline the process of "devising and revising" a research question, be it descriptive, relational, or comparative. After reading their paper, write a three-page paper that addresses the following:

 

  • How do descriptive research questions differ from questions of relationship? From questions of comparison?

 

  • How should a researcher determine if prior research exists on her intended research topic?

 

  • What factors should be used to gauge the quality of previous research? Why are these important in making this assessment?

 

  • Should formulation of a research question precede or follow consultation with the scholarly literature? Please explain.

 

Assignment Expectations

 

 

 

 

  • You are expected to consult the scholarly literature in preparing your paper; you are also expected to incorporate relevant background readings.

 

  • Your paper should be written in your own words. This will enable me to assess your level of understanding.

 

  • In order to earn full credit, you must clearly show that you have read ALL required background materials.

 

  • Be sure to cite your references in the text of all papers and on the reference list at the end. For examples, look at the way the references are listed in the modules and on the background reading list.

 

  • Proofread your paper to be sure grammar and punctuation are correct and that each part of the assignment has been address clearly and completely.

 

 

 

 

Length: 3 pages typed, double-spaced.

 

 

1B. The SLP for this course is designed to allow you to apply the research concepts and principles introduced throughout this course to a "real-world" health problem. As such, you will be asked to devise your own research question, to use the empirical literature to identify knowledge gaps in the field with regard to that research question, formulate a corresponding research hypothesis, propose an appropriate study design for testing that research hypothesis, and devise a sampling and recruitment plan to strengthen the generalizability of your study’s findings. In Module 5, you will upload a final paper consisting of all of these elements.

Your Task for this Assignment

After reading the background materials for this module, select one of the following research topics and derive a corresponding research question. Next, write a 2- to 3-page paper in which you identify your research question and apply the "Attributes of a ‘Good’ Research Question":

 

 

 

  • Obesity and Diabetes Risk

 

  • Physical Activity and Stroke Risk

 

  • Health Insurance Status and Health Care Utilization

 

  • Education and Mortality Risk

 

  • Drug Addiction and Criminal Behavior

 

  • Cancer Therapy [1] and Tumor Growth

 

 

Your paper should clearly delineate the extent to which each of the following criteria has been satisfied in formulating your research question:

 

  • Relevance

 

  • Novelty

 

  • Focus

 

  • Consisting of two core concepts (at minimum)

 

  • Feasibility

2A. Case Assignment

Health science researchers have long believed the randomized controlled trial (RCT) to be the "gold standard" of study designs. There are many reasons for their contention that an RCT should be preferred to any of the observational study designs. However, there are also instances in which employment of this design would be inappropriate.

In a four-page paper, discuss the merits of the RCT as a study design with regard to:

 

 

 

  • Internal validity

 

  • Confounding

 

  • Feasibility/appropriateness

 

  • External validity

Length: 4 pages typed, double-spaced.

 

 

2B. The next step in the research process is immersing oneself in the empirical literature on your research topic to determine the extent to which your research question (identified in Module 1) has been addressed. To this end, please use the Trident University Online Library to conduct a literature search on your research topic.

Remember, your goal is to discover the extent to which a knowledge gap exists with regard to your specific research question. Locate five peer-reviewed journal articles that present studies relevant to your topic, and synthesize these into a four-page paper that summarizes the "current state of knowledge" with regard to your research question. Note specifically,

 

  • Study findings relative your research question (positive, negative, and inconclusive)

 

  • Any additional questions left unanswered by these studies

 

  • How addressing your research question would help to fill a knowledge gap (should your research question fall short of this, you may need to propose an alternative one)

 

  • The specific population to which your study will apply (and ultimately, your study’s targeted sample)

3B. Suppose that your research topic is "milk consumption and bone fracture risk." A corresponding research question would thus be: "What is the relationship between daily consumption of milk and bone fracture risk?"

A review of the empirical literature suggests that milk consumption may decrease the likelihood of bone fracture, but findings reported are limited to women ages 65 and above. You would like to examine this relationship in a different segment of the population; let’s say school-aged youths. Given that prior research suggests a relationship exists, you might hypothesize the following:

Research Hypothesis (one-tailed):

Ho: School-aged youths who consume milk on a daily basis are equally as likely or more likely (than those who do not) to experience bone fractures.

Ha: School-aged youths who consume milk on a daily basis are less likely to experience bone fractures.

…where Ho reflects the null hypothesis and Ha the alternative hypothesis, which corresponds to the outcome that you, the researcher, expect to observe. Another way of stating your hypothesis would be in two-tailed format, i.e.,

Research Hypothesis (two-tailed):

Ho: There is no relationship between daily milk consumption and bone fracture risk among school-aged youths.

Ha: There is a relationship between daily milk consumption and bone fracture risk among school-aged youths.

(Two-tailed hypotheses are used in instances in which a research is not able to anticipate the direction of a hypothesized relationship.)

Your Specific Task for this Assignment

Using the examples provided about, formulate your own research hypothesis corresponding to the research question you selected in Module 1. Add this to the previous components of your SLP, ensuring that there is consistency from research question-to-literature review-to- research hypothesis. (Your research hypothesis should correspond directly to your research question; if this is not the case, please revise either accordingly.)

Upload the resultant document, which should be 6-7 pages in length, for my review.

4A. researcher wishes to operationalize her study variables in the following manner. How might she go about doing so? Summarize your responses in tabular form (see example below), and supplement your table with a supporting narrative.

 

  • Age (continuous)

 

  • Gender (dichotomous)

 

  • Ethnicity (categorical)

 

  • Education (ordinal)

 

  • Income (continuous)

 

  • Marital status (categorical)

 

  • Weight (continuous)

 

  • Blood pressure (continuous)

 

  • Hypertension (dichotomous)

 

  • Body temperature (continuous)

 

  • Health insurance status (categorical)

 

  • Smoking status (dichotomous)

EXAMPLE:

 

 

 

Variable:

Name

Type

How operationalized

How measured

Age

Etc.

continuous

Age in years

How old were you on your last birthday?

 

 

Narrative: When age is operationalized in this manner, one would merely need to query the respondent to determine the age she turned on her last birthday. Alternatively, the researcher could ask the respondent to provide his birth date and year, and then calculate age at a later time.

4B. Once a research hypothesis is formulated, the researcher must decide upon an appropriate study design to test that hypothesis. In doing so, she must take into consideration the extent to which that design will optimize the internal validity of her study findings (refer again the discussion of internal validity in Module 2). Also to be considered are the practical factors that may facilitate or inhibit implementation of particular study designs, e.g., limited access to one’s target population over time due to transiency among prospective research subjects may preclude adoption of a cohort study design.

Your Task for this Assignment

With the aforementioned factors in mind, identify a study design (experimental or observational) that would be appropriate to test your study’s research hypothesis, and address the following questions in a three-page essay:

 

  • What are the components of this design?

 

  • Would this design be considered experimental or observational? Why?

 

  • Why did you choose this design over others? Be sure to note all advantages and disadvantages of employing this design to address your particular research question.

 

  • To what types of bias is this design most vulnerable? Please explain.
