NURSING DL-F, Applied Nursing Research Quizlet, Quiz 5 (Questions with Correct Answers) 2023/2024. What is the gold standard approach to analyzing data from a clinical trial when there is attrition from the study? Selected Answer: D. Intention-to-treat analysis Answers: A. Power analysis B.

Instituting manipulation checks B. Having standardized research protocols C. Maximizing precision D. Using a homogeneous sample Response Feedback: The careful development of standard protocols is an important strategy for enhancing constancy of conditions in implementing an intervention; monitoring adherence to the protocols is also an important aspect of intervention fidelity. Using a homogenous sample and instituting manipulation checks do not contribute to the faithful implementation of an intervention. Efforts to maximize precision include using highly accurate measures and controlling confounding variables, but these are unrelated to efforts to achieve intervention fidelity.
