Why is the literature review often limited in a study using grounded theory methods?
Limiting the literature review ensures that the researcher's personal biases are bracketed.
Theories are expected to emerge directly from the data and not from previous research.
Grounded theory is more sensitive to cultural values than to the researcher's values.
Research using grounded theory methods is sparse.
The Correct Answer is B
Choice A rationale
Bracketing is a specific technique used primarily in phenomenology to set aside the researcher's preconceived notions and experiences. While minimizing bias is important in all research, the limitation of the literature review in grounded theory is not specifically about the act of bracketing personal biases. Instead, it is a strategic move to ensure the developed theory is truly inductive. Bracketing is a distinct conceptual process used to manage subjectivity throughout the entire qualitative inquiry.
Choice B rationale
Grounded theory utilizes an inductive approach where the researcher seeks to develop a theory based solely on the data collected from participants. By delaying a comprehensive literature review, the researcher prevents existing theoretical frameworks from predetermining the themes or categories that might emerge. This ensures that the resulting theory is grounded in the actual lived experiences and social processes observed during the study, rather than being forced into the mold of established research.
Choice C rationale
While qualitative methods like grounded theory are sensitive to cultural contexts and the participants' values, this sensitivity is not the primary reason for limiting the literature review. The restriction is a methodological requirement to maintain the purity of the inductive process. Cultural sensitivity is achieved through immersion and open-ended data collection rather than by avoiding previous studies. The goal is to allow the participants' voices to shape the theory without the interference of external academic constructs.
Choice D rationale
Grounded theory is a well-established and frequently used methodology in nursing and social sciences; therefore, it is incorrect to state that research using these methods is sparse. There is a vast body of grounded theory literature available across many disciplines. The decision to limit the initial review is purely a design choice intended to promote theoretical sensitivity and ensure the uniqueness of the new theory, not a reflection of the quantity of existing research.

Correct Answer is A
Explanation
Choice A rationale
In the PICO framework, the C stands for Comparison. This component identifies the alternative to the primary intervention being considered. It allows the researcher or clinician to contrast the effectiveness of a new treatment against the current standard of care, a placebo, or no intervention at all. Including a comparison is vital for determining if a proposed change in practice actually yields superior results, providing a clear benchmark for evaluating the evidence collected.
Choice B rationale
Although the PICO framework is used in clinical settings, the letter C does not stand for clinical. The entire framework is designed for clinical inquiry, so using the word clinical for one specific letter would be redundant and lack specific utility in structuring a search. The framework is meant to break down a complex clinical scenario into searchable parts: Population, Intervention, Comparison, and Outcome. Using the correct terms ensures that literature searches are precise and relevant.
Choice C rationale
Consequence is not a standard part of the PICO acronym. While the consequences of an intervention are important, they are usually captured under the O, which stands for Outcome. The Outcome component measures the results or effects of the intervention and comparison. Introducing consequence as the C would confuse the structure of the mnemonic, which is specifically designed to help clinicians find research that compares two different approaches to a specific clinical problem or population.
Choice D rationale
Control is a term often used in experimental research to describe the group that does not receive the experimental treatment. While a control group can serve as the Comparison (C) in a PICO question, the letter itself specifically stands for Comparison. This is a broader term that encompasses any alternative being studied, not just a strict experimental control. Using the term Comparison allows for a wider range of evidence-based queries, including those comparing two different active treatments.
Correct Answer is A
Explanation
Choice A rationale
Approval by an Institutional Review Board (IRB) is the primary indicator that a study adhered to ethical standards, such as those outlined in the Belmont Report. The IRB independently reviews the study design to ensure participant protection, informed consent, and a favorable risk-to-benefit ratio. This oversight confirms that the research respects personhood, beneficence, and justice. Seeing this approval in a report provides the most direct evidence that ethical guidelines were scrutinized by an objective committee.
Choice B rationale
Discussing sampling techniques relates to the methodological rigor and external validity of a study rather than its ethical integrity. While choosing vulnerable populations requires ethical justification, the mere description of how subjects were selected does not prove that their rights were protected. Ethical standards specifically involve consent processes, anonymity, and safety protocols. Sampling discussions focus on how representative or appropriate the participants are for the research questions, which is a separate concern from ethical oversight.
Choice C rationale
Reliability and validity refer to the psychometric properties of research instruments and the overall accuracy of the findings. These are measures of technical quality and scientific merit in quantitative research. While conducting poor quality research can be seen as an ethical issue regarding resource waste, these metrics do not confirm adherence to human subject protection laws. Reliability ensures consistency of results, and validity ensures accuracy, but neither confirms that participants were treated ethically or provided informed consent.
Choice D rationale
Transparent data analysis procedures are essential for the auditability and reproducibility of a study, but they do not confirm ethical compliance. Analysis occurs after data collection is complete and focuses on interpreting the information gathered. Ethical concerns are most prominent during the recruitment and data collection phases where direct interaction with human subjects occurs. Detailed analysis descriptions provide evidence of intellectual honesty and technical skill, yet they are distinct from the formal ethical clearance provided by oversight bodies.
