CITI Training - Research Study Design - All Modules Questions and Answers Graded A In the case of interventional research, the research question should specify which of the following? The population of individuals that researchers are interested in examining What does the Institutional Review Board (IRB) do? Reviews proposed research in order to assess that the research is in keeping with ethical guidelines and regulatory requirements in order to protect human subjects. The alternative hypothesis states that the connection between key factors of interest and any observed connection is most likely: Not due to chance Which of these is the first step in specifying the direction that research will take? Research question A hypothesis serves as: A proposed mechanism by which key factors relevant to a research question interact with one another A successful literature review will depend on how relevant and comprehensive the chosen database is to the topics of interest, the search parameters, and which of the following? Chosen search terms Which methodology best describes observational research designs? No manipulation of study variables and no randomization of subjects A group of researchers want to examine the age, gender, and socioeconomic status of patrons of a local café chain. What research design is this? Descriptive Research A group of researchers want to examine the effects of "Boston cream" donuts versus "glazed" donuts. They observe a group of people who only eat Boston cream donuts and another group that only eats glazed donuts. The groups are going to be followed for ten years and the occurrence of diabetes will be compared amongst the two groups. What type of study is this Prospective Cohort A group of researchers find that very few café customers are willing to talk to them. So, they now decide to look at public records available online at the Centers for Disease Control and Prevention (CDC). They intend to access diabetes prevalence data in each state. They are then going to examine the number of café franchises in each state. Finally, they will look for a relationship between the number of café franchises and diabetes prevalence. What type of study is this? Correlational The objectives of descriptive epidemiology are to address who, what, where, when, and how much of a variable under study is occurring. Which area would be most appropriate for a descriptive research design? Determine the prevalence of teenage pregnancies Researchers decide to find one customer who is willing to speak to them about their donut consumption. Apparently, this customer only started patronizing a certain café chain two months ago. Around the same time, she began experiencing migraine headaches. The researchers decide to do an in-depth analysis of this one case. What type of study is this? Case Study Researchers are testing the effects of a new weight loss method. Subjects will be randomly assigned to groups. One group will follow the new method and the other group will not. All subjects will be randomized a second time to watch a nutritional information video and the other group will receive a motivational speech. This will result in four different groups as follows: Weight Loss Method + Motivational Speech Weight Loss Method + Informational Video No Weight Loss Method + Motivational Speech No Weight Loss Method + Informational Video
