NURSING DL-F, Applied Nursing Research Quizlet (Quiz 6) 2023/2024 – Florida National University. A nurse researcher used a randomized crossover design to test the hypothesis that watching a music video would improve the sleep quality of older adults with chronic insomnia. What type of trial was this? Selected Answer: B. A superiority trial Answers: A. A noninferiority trial B. A superiority trial C. A sequential trial D. An equivalence trial Response Feedback : The researcher undertook a standard superiority trial in which it was hypothesized that the music video was superior to the absence of the music video (i.e., would lead to improvements). A noninferiority trial tests whether an intervention is no worse than (not inferior to) a reference treatment. Equivalence trials test whether alternative interventions are equal. A sequential clinical trial involves ongoing analysis of data to see if the trial can be stopped based on available evidence.  Question 2 5 out of 5 points Evaluation research can address many different objectives. Which type of evaluation analysis uses experimental or quasi-experimental designs with the aim of making causal inferences about the effects of the program being evaluated? Selected Answer: D. An impact analysis Answers: A. An outcome analysis B. A process analysis C. A cost analysis D. An impact analysis Response Feedback : An impact analysis assesses a program’s impacts that can be attributed to the program (net impacts). Impact analyses use an experimental or quasi-experimental design because the goal is to permit causal inferences about program effects. Process analyses, which focus on the implementation and operation of the program, use descriptive designs. An outcome analysis examines whether the program is meeting its objectives and does not rely on experimental designs. A cost analysis considers the cost of operating the program, not its effects on substantive outcomes.  Question 3 5 out of 5 points In the context of a study, what is sampling? Selected Answer: A. Selecting a subset of the population to represent the entire population Answers: A. Selecting a subset of the population to represent the entire population B. Identifying a set of criteria for selecting study participants C. Ensuring that every element in the population has an equal chance of being included in the study D. Determining who could participate in a study Response Feedback : Sampling is the process of selecting a portion of an entire population. Eligibility criteria are used to define population characteristics and to identify people who could participate in a study. Some sampling strategies ensure that every element in the population has a chance to be sampled, but most strategies used by nurse researchers do not.  Question 4 0 out of 5 points What is the term used to describe trials that attempt to bridge the gap between Phase III efficacy studies and Phase IV effectiveness studies? Selected Answer: C. A sequential clinical trial Answers: A. A randomized controlled trial B. A pragmatic clinical trial C. A sequential clinical trial D. An explanatory clinical trial Response Feedback : Pragmatic (or practical) clinical trials (PCTs) strive to maximize external validity (a major focus of Phase IV trials) with minimal negative effect on internal validity (a focus in Phase III trials). PCTs address practical questions about the effects of the intervention in routine clinical settings. A Phase III RCT is sometimes called an explanatory trial. A sequential clinical trial involves ongoing analysis of data to see if the trial can be stopped based on available evidence.  Question 5 5 out of 5 points Evaluation research can address many different objectives. Which type of analysis provides information about how a program being evaluated actually functions? Selected Answer: A. A process analysis Answers: A. A process analysis B. A cost analysis C. An outcome analysis D. An impact analysis Response Feedback : A process (or implementation) analysis provides in-depth descriptive information about the process by which a program gets implemented and how it actually operates. An outcome analysis examines whether the program is meeting its objectives, and an impact analysis examines program effects. A cost analysis considers the cost of operating the program, usually in relation to its benefits.  Question 6 5 out of 5 points What is the technical name for the list of all elements in a population? Selected Answer: D. A sampling frame Answers: A. A seed B. A stratum C. A sampling network D. A sampling frame Response Feedback : Researchers establish a sampling frame (a list of all elements in the population) for the purposes of random sampling. A stratum is a subdivision of a population, not a listing of elements. A seed is the point of origin in snowball sampling. The term “sampling network” is not a research term.  Question 7 5 out of 5 points A nurse researcher is studying the well-being of people with frequen
