UTA nurs4325 week 3 RAC 2 Lee et al. 2016 october 2020
A major skill that is learned in this course is how to critically read and critique nursing research articles. The purpose for critiquing an article is to critically evaluate the research process followed by the author(s) of the assigned article. This is an information-intensive, time-intensive process that is not learned overnight. To demonstrate your skill at critiquing an article, you will complete this open-book multiple choice assignment.

Here’s how you should approach completing this week’s assignment to begin critiquing an article:
1. First, do your assigned reading in Grove & Gray (2019) and complete the reading worksheets early in the week. This will introduce you to the critique skills you will need for the week.
2. Skim the entire instructor assigned research article that has been posted in Module One for you so that you will have an idea of what it is about. Lightly cross out the abstract for the article (you won’t be using it). Then, for this week, re-read carefully the article from the methods section through the end of the article.
3. Print the Research Article Critique, Part Two and find the best answer to each question based on your assigned reading for the week and on what you have read in the instructor assigned research article.
4. Some of the questions in the critique assignment below will seem unfamiliar to you. Look up key terms from the question in your textbook. Some examples of these terms might be: problem statements, hypotheses, or variables. You can also look in Chapter 12 for an example of a critical appraisal (or critique) of a quantitative research article.
5. Once you have completed this assignment “on paper”, enter your answers by the assignment due date and time listed in the syllabus. Ignore any wording that indicates that “this is a test” and carefully enter your answers from this document.
6. You will have two access attempts to record your answers. You are welcome to use the second attempt to improve your grade, but you will only receive a grade on your first attempt, and not feedback on which questions you may have missed. The highest of the two submissions will be recorded as your final grade if you choose to submit a second time.
7. This RAC is intended to be your own work. Do not discuss the questions with other students online or any other way. Doing so would be collusion and will be reported to the Office of Community Standards.
1. What sampling method or plan was used by the authors in this study?
Simple random sampling
Convenience sampling
Systematic sampling
Network sampling
2. According to Grove and Gray (2019), which of the following best describes the potential biases of this sampling method?
This is a strong probability sampling method with very little potential for bias.
This method is used when an ordered list of all members of the population are available, and provides a random but not equal chance for inclusion in the study.
This method provides little opportunity to control for bias because subjects are included in the study merely because they happen to be in the right place at the right time.
This method is specific to the individuals who were recruited and the information gained cannot be generalized to others who don’t share these types of experiences.
None of the above biases best describe the sampling method chosen by the author.
3. What was the final sample size reported by the authors for this study?
21 pairs of patients and caregivers
148 pairs of patients and caregivers

The authors mention that an power analysis was conducted, and 127 matched pairs were determined to be needed for the study.
The authors do not report that a power analysis was conducted.

20. There are several statistically significant findings in this study. Which statement from the article would be considered a significant result?
Both patients and the caregivers perceived an average of six to seven physical symptoms caused by the injury, but the mean subscale scores for causes among both patients and caregivers were low, indicating that both groups had weak perceptions about the reasons for injury (t = -2.15, p = .033).
The average score for patients on the control/cure subscale was 3.71 (SD = 0.72).
Approximately 69% of caregivers did not share care responsibilities.
Caregivers who did not share caring responsibilities perceived better control or cure than did those who had someone to share their care work (t = -3.38, p = .001).
21. Which one of these statements from the article would be considered a non-significant result?
Caregivers perceived more physical symptoms, believed that the time required to recover would be longer, and saw more consequences when they cared for an injured patient alone.
Both patients and the caregivers perceived an average of six to seven physical symptoms caused by the injury, but the mean subscale scores for causes among both patients and caregivers were low, indicating that both groups had weak perceptions about the reasons for injury (t = -2.15, p = .033).
Caregivers who did not share caring responsibilities perceived better control or cure than did those who had someone to share their care work (t = -3.38, p = .001).
Caregivers had positive perceptions on controlling or curing the injury when they cared for patients alone.
22. Which one of these statements from the article would be considered clinically important?
Patients and caregivers held similar illness perceptions toward the injury in this study.
In this study, 70% of the patients were injured by vehicle accidents, while 30% were injured by falls.
It is essential that clinicians help those patients and caregivers to express and organize any discrepancies between their illness representations and the medical treatments the patients are given.
The average score for patients on the control/cure subscale was 3.71 (SD = 0.72).
23. Which statements below, as reported by the author, would be considered a limitation of the study? (Select all that apply)
The study population included a convenience sample of patients and caregivers recruited from a teaching hospital in Taiwan.
Health care providers must recognize the importance of caregiver illness representations.
Future studies of caregivers should compare caregivers who receive supportive services to those who do not.
The cross-sectional nature of the present study precludes learning about changes over time for any of the target variables.
24. Which of these statements would be considered a statement regarding generalization of these results?
The sample included patients with injury and their caregivers recruited from a teaching hospital in Taiwan and therefore decreases the ability to generalize to all patients with injury and their caregivers.
The results of this study can be generalized to caregivers of patients with severe brain injuries or stroke.
The Chinese Illness Perception Questionnaire Revised-Trauma (the Chinese IPQ-R-Trauma) has demonstrated acceptable reliability and validity in this and previous studies; as such, the results of this study can be generalized to all patients with injury and their caregivers.
The sample included patients with injury and their caregivers recruited from a teaching hospital in Taiwan and therefore the results of this study can be generalized without caution to all patients with injury and their caregivers from all teaching hospitals in Taiwan.
25. Which of these statements from the article would be considered a recommendation for future studies? (Select all that apply)
There were no significant differences in the scores for seven of the eight subscales between the patients and caregivers.
Determining whether or not these findings are translatable to other cultures may require further investigation.
Injury severity might be a significant factor for illness representations, but further testing is required to make a clear determination in that regard.
These results may indicate that being admitted to an ICU typically means that the patient has a more serious injury, which may cause many problems for the caregiver.
