For postgraduate researchers (PGRs) and early career researchers (ECRs) in professional doctorates, embarking on research can sometimes feel like stepping into a foreign land, full of unfamiliar words, contested meanings, and competing traditions. Terms like “ontology”, “epistemology”, or “rigour” can appear daunting, yet these concepts shape the very foundations of how we design and conduct research.

This blog draws together insights from two DProf Health and Social Care teaching sessions, The Language of Research and The Research Process, to provide a clearer pathway through this terrain.

Why language matters in research

Language is not neutral. The words we use reflect our philosophical assumptions, our methodological choices, and our positionality as researchers. To speak of “validity” or “credibility” is not just semantics, it signals the kind of knowledge we value and how we believe it should be produced.

Understanding research language matters because:

• It connects to our ontology (what we believe reality is),
• It informs our epistemology (how we believe knowledge is generated),
• It expresses our axiology (the values and ethics that shape research),
• And it influences our methodology (the design and approach we adopt).

Professional doctorate scholars must learn to navigate this “language labyrinth” with care, not simply to pass an assessment but to situate themselves as credible contributors to both academic and professional communities.

Paradigms and misconceptions

One of the most helpful ways of thinking about research is through paradigms. These are broad philosophical traditions that guide how research questions are framed and answered.

Positivist or quantitative traditions are often caricatured as “number crunchers”. Common misconceptions include:

• Quantitative research is only about numbers. In reality, interpretation of patterns and relationships matters as much as measurement.
• Statistical significance equals practical significance. A result can be statistically significant without being meaningful in practice.
• Quantitative research is always objective. Bias can creep in through design, data collection, or analysis.
• Bigger samples are always better. Quality and design often matter more than sheer size.

Interpretivist or qualitative traditions are sometimes dismissed as “fluffy bunnies”. Misconceptions include:

• Qualitative research lacks rigour. In fact, it has robust criteria such as credibility, dependability, confirmability, transferability, and intelligibility.
• It is just anecdotal. Rich description can reveal deep insights unavailable to quantitative approaches.
• It cannot be generalised. While not statistically generalisable, findings can be transferable to similar contexts.
• It is easier to conduct. In reality, it demands skill, time, and careful planning.

For professional doctorates, both paradigms are valuable. Quantitative approaches can provide breadth, while qualitative approaches offer depth. Many studies draw on mixed methods to capture the complexity of practice-based issues.

The thread of rigour

Despite differences between paradigms, what unites all research is the requirement for rigour. Rigour means being meticulous, consistent, and transparent in order to produce trustworthy findings.

• In positivist research, rigour is often associated with validity (measuring what you intend to measure) and reliability (achieving stable and repeatable results).
• In interpretivist research, rigour involves credibility (faithfulness to participants’ experiences), dependability (transparent processes), confirmability (minimising researcher bias), and transferability (usefulness in other contexts).

Rigour, then, is not the preserve of any one paradigm. It is the hallmark of scholarship.

Understanding the research process

Moving beyond language and paradigms, professional doctorate scholars must also engage with the research process itself. While often presented as linear, in reality it is cyclical, with choices and trade-offs at each stage.

Key stages include:

1. Defining a problem or gap – asking questions that matter to practice and theory.
2. Choosing an ontological and epistemological stance – clarifying your philosophical assumptions.
3. Designing the study – selecting methodologies and methods that align with your stance and question.
4. Ensuring quality – applying appropriate criteria for rigour and trustworthiness.
5. Conducting research ethically – reflecting on positionality, values, and responsibilities.
6. Analysing and interpreting data – always mindful of your own influence.
7. Communicating findings – in ways that are meaningful to both academic and professional audiences.

As the Socratic reminder goes, “life without inquiry is not worth living”. For doctoral researchers, this inquiry is not abstract, it is embodied in your own curiosity and professional context.

Choices, trade-offs, and reflexivity

One of the most important lessons in navigating the research process is that there are no absolute answers. Ontologies exist on a continuum, not as binaries. Methodologies and methods involve trade-offs, not perfect solutions.

Recognising this brings reflexivity to the fore. Professional doctorate researchers are both practitioners and scholars, positioned within the worlds they study. Being explicit about positionality, and being reflexive about the influence you have on your research, are not optional extras. They are part of your ethical duty.

Final reflections

For professional doctorate PGRs and ECRs, navigating research is not just about mastering methods. It is about understanding the language we use, the paradigms and the methodologies that underpin our choices, and the processes that bring rigour and meaning to inquiry.

Your challenge is to embrace complexity without being paralysed by it, to be transparent about your assumptions, and to connect your professional knowing with applied scholarly knowing. In doing so, you will not only complete a thesis but contribute to knowledge that matters, both within academia and in the professional world.
