Which phrase correctly defines a theory?

Choice A rationale

This principle emphasizes the autonomy of individuals, treating them as independent agents capable of self-determination. In research ethics, it ensures that participants are provided with sufficient information to make informed decisions without coercion or undue influence. It requires researchers to respect the choice of a prospective subject to enter or decline participation. This foundational ethical concept protects human dignity and prevents the exploitation of vulnerable populations within clinical research settings.

Choice B rationale

This ethical obligation requires researchers to maximize potential benefits while minimizing any possible harms to the participants. It involves a careful risk-benefit analysis to ensure that the study is safe and that the knowledge gained justifies any minor discomforts. While critical for the overall design of a study, it does not specifically address the individual's right or freedom to choose participation, which is the primary focus of autonomy or respect for persons.

Choice C rationale

This principle focuses on the fair distribution of the burdens and benefits of research. It ensures that specific groups, such as the poor or minorities, are not unfairly targeted for risky research while others reap the benefits. It involves equitable subject selection and avoids systematic bias in recruitment. While it promotes fairness in the research process, it does not directly govern the individual's psychological freedom to provide informed consent or withdraw from a study.

Choice D rationale

This refers to the researcher's obligation to protect the privacy of the participants by ensuring that their personal information and data are not disclosed to unauthorized parties. It is a vital component of the research relationship that builds trust and maintains the integrity of the data collected. However, it is a post-recruitment protection mechanism rather than the initial ethical principle that empowers a subject to choose whether they want to participate in the first place.

Choice C rationale

Qualitative research is fundamentally rooted in the interpretative paradigm, aiming to capture the emic or insider perspective of individuals. It explores the meaning, social context, and subjective reality of human experiences. By using methods like interviews or ethnography, researchers gain an in-depth understanding of how people perceive their world. This approach values the uniqueness of the individual voice and seeks to describe complex phenomena that cannot be easily reduced to numbers or rigid categories.

Choice B rationale

Large, randomly selected samples are a hallmark of quantitative research, specifically designed to ensure that findings can be generalized to a broader population. Qualitative research, conversely, often uses small, purposeful samples to achieve depth rather than breadth. Randomization is not utilized because the goal is not to eliminate bias for statistical inference, but to select participants who have lived the specific experience under study. Using large samples in qualitative work would often result in unmanageable volumes of data.

Choice A rationale

Hypothesis testing is a deductive process used in quantitative research to determine if there is a statistically significant relationship between variables. It relies on objective measurement and mathematical evidence to accept or reject a null hypothesis. Qualitative research is typically inductive, meaning it seeks to generate theory or descriptions from the data rather than testing preconceived notions. Therefore, the results of qualitative studies are expressed through themes and narratives rather than the confirmation of formal hypotheses.

Choice D rationale

Qualitative research rarely claims to provide definitive, final conclusions in the way that clinical trials might establish a treatment effect. Instead, it provides a rich, contextualized understanding of a phenomenon that can evolve. The findings are often seen as a baseline for further inquiry or a way to understand the nuances of a specific group. Because the work is subjective and context-dependent, the goal is discovery and description rather than establishing a singular, universal truth for all.
