QuestionuestionResearch Article Critique, Part Two Self-efficacy and stress among...Research Article Critique, Part Two  Self-efficacy and stress among informal caregivers of individuals at end of life(Hampton & Newcomb, 2018)  Instructions: 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 finish open-book multiple choice assignment. Here's how you should approach completing this week's assignment to finish critiquing an article: 1. First, read assigned reading in Grove, Gray, and Burns (2015) 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 on Blackboard 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 from the study's methods section through the end of the article. 3. Print this document and find the best answer to each question below based on your Grove, Gray, and Burns (2015) assigned reading for the week and 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: power analysis, inter-rater reliability, and generalization. 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", go into blackboard and enter your answers by the assignment due date and time listed in the syllabus. Ignore any wording from Blackboard 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. This is given to you so that if you encounter technical difficulties on your first attempt, or you would like a second attempt to try to improve your grade, you may do so. You will not be able to see the questions that you missed when you submit your attempt. Blackboard will record the highest grade from the two submissions. If you have questions about this assignment, you can post them to your group discussion board for help. Please do not post the exact question from the assignment below and ask the group for the answer as this would constitute academic dishonesty. Questions 1 - 9: Sample. (For help with these questions, refer to chapters: 9 & 12)1. What sampling method or plan was used by the authors in this study?a. Simple random samplingb. Systematic samplingc. Convenience samplingd. Network sampling 2. According to Grove, Gray, and Burns (2015), what are the potential biases of this sampling method?a. This is a strong probability sampling method with very little potential for bias.b. 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.c. 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.d.

(For help with these questions, refer to chapters 11 & 12)20. There are several statistically significant findings in this study. Which statement from the article would be considered a significant result?a. Caregivers reported the lowest level of confidence in caring for themselves (x2 = 5.46, SD = 1.83).b. The average score on the PSS was 18.26 (SD = 7.17), but almost half (43%) of surveyed caregivers in this sample scored 20 or greater on the PSS.c. Forty-three percent of surveyed caregivers reported high levels of perceived stress, and caregivers in this sample indicated the presence of more anxiety and depression than the general SF12V12 database population.            d. Caring for oneself correlated significantly with perceived stress (r = -0.63, p = < .01) and                        predicted 38% of the variance in PSS scores.             21. Which one of these statements from the article would be considered a non-significant result?a. Significant relationships between the additional CGI subscale scores and perceived stress (PSS) score were not detected.b. Overall, caregivers reported a moderate level of confidence in their ability to manage caregiving demands, which was indicated by the CGI total score (x2 = 26.81, SD = 5.10).c. Despite reports of above average physical health (51st percentile rank) in the current sample, 82% of the surveyed caregivers rated perceived mental health below the SF12v12 general population (43rd percentile rank).            d. Caregivers' percentile rankings on individual attributes of the SF12v12 ranged from 43.45 to                48.68. 22. Which one of these statements from the article would be considered clinically important? (Select all that apply)            a. Self-efficacy for self-care is a significant weakness for informal caregivers.           b. Overall, caregivers reported a moderate level of confidence in their ability to manage                          caregiving demands, which was indicated by the CGI total score (x2 = 26.81, SD = 5.10).           c. An inconsistency with previous literature was the finding that participants generally                   reported higher than average scores on physical health.           d. A finding from this study are particularly important for nurses who interact with                         informal caregivers, is that a significant negative correlation exists between caregiver                 perceived stress and caregiver mental health ranking.                       23. Which statements below, as reported by the author, would be considered a limitation of the study? (Select all that apply)a. The study population included a convenience sample of informal caregivers who were receiving some level of caregiving support from an agency that provided end-of-life supportive services.b. Health care providers must recognize the importance of caregiver self-efficacy.c. Future studies of caregivers should compare caregivers who receive supportive services to those who do not.d. 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?a. The sample included adult informal caregivers recruited from community-based hospice agencies and therefore decreases the ability to generalize to all adult informal caregivers.b. The results of this study can be generalized to ethnic adult informal caregivers.c. The Perceived Stress Scale (PSS) has demonstrated acceptable reliability and validity in this and previous studies; as such, the results of this study can be generalized to all adult informal caregivers.d. The sample included adult informal caregivers recruited from community-based hospice agencies and therefore the results of this study can be generalized without caution to all adult informal caregivers receiving support from community-based hospice agencies. 25. Which of these statements from the article would be considered a recommendation for future studies? (Select all that apply) a. Significant relationships between the additional CGI subscale scores and perceived stress (PSS) score were not detected.b. Future studies of caregivers should compare caregivers who receive supportive services to those who do not.c. Future research should include longitudinal studies in order to measure changes in stress and self-efficacy over time.            d. Because identification of factors that reduce negative outcomes is vital to the psychological     and physical health of informal caregivers, researchers should study the influence of self-        efficacy on caregivers providing care to patients with diverse health conditions. Health ScienceScienceNursingNURS 3321Share Question
