AHS 341 Health Sciences Research Methods Quiz 3 Q1). Identify the type of survey item shown in the following example (in blue font) On a scale of 1 to 5 (with "1" being "very poor" and "5" being "excellent"), how would you rate the attentiveness of your medical provider during your most recent appointment at our clinic?  1 2 3 4 5 Answer: Likert scale item (Response options for Likert scale items are arranged in order ("on a scale of 1 to 5") to indicate the degree of agreement (in this case with the attentiveness of the medical provider). Although the response options consist of numbers, the extreme numbers represent completely opposite ends of a spectrum (with "1" being "very poor" and "5" being "excellent".) Q2). You are developing a patient satisfaction survey to give to adult patients at your clinic. Below is an item in the survey (in blue font) . Identify the weakness of the item. How would you rate your medical provider and the reception desk (select one)? Very Good     Good     Fair     Poor   Very Poor Answer: The survey item asks for the rating of two different groups of professionals and should be divided into two survey items . “The item is relevant to the objective of the survey, there is an appropriate number of ,response options for the survey item, and the survey item is appropriate for adult patients. However, the item "How would you rate your medical provider and the reception desk (select one)?" is asking respondents to evaluate two different groups of medical providers but only allows one response. If a patient has a positive assessment of his or her medical provider but a negative assessment of the reception desk, there is not an option for him or her to select one assessment for the medical provider and the other for the reception desk.” Q3). We are conducting a study to determine if a new antihypertensive medication is effective. We recruit eligible adults with similar levels of hypertension for the study. Then, we randomly assign each subject into two groups: the experimental treatment group (which received the new antihypertensive medication) and the active control group (which received treatment with an established antihypertensive medication). After both groups are treated with their respective antihypertensive medications, we compare the blood pressure measurements of both group. Based on this information, this study is most likely a(n) _____ study.
Answer: True experimental research design (The trademark of the true experimental research design is the random assignment of subjects to treatment groups. Random assignment does not occur in either the quasi-experimental study, the correlational research design, nor the descriptive research design.) Q4). We are conducting a qualitative research study, and we need to establish trustworthiness. We collect data with focus groups, direct observation, and individual interviews. We interact with the study participants for more than one year. We also verify with study participants that we accurately transcribed their discussions.  Based on this information, which technique did we not use to establish trustworthiness? Answer: Peer debriefing “While we used prolonged engagement, member checking, and triangulation, we did not ask an individual who had not been involved in data collection to provide an "outsider's" review of the data.” Q5). We are investigating a 40-year-old man diagnosed with the rare disease yellow fever. We interview the man about his activities (which included extensive traveling) prior to his diagnosis. We also observe the man for long periods of time. Based on this information, what type of qualitative research are we conducting? Answer: Case study research (We are focusing our research on one man with the rare disease and collect data for long periods of time).
