Constructivist Grounded Theory - A simple introduction to Kathy Charmaz’s approach
Constructivist grounded theory.
It sounds like one of those phrases that appears in a methodology chapter and immediately makes everything feel more complicated than it needs to be.
What does it actually mean?
How does it work?
And how is it different from other forms of qualitative research?
If you’ve been asking those questions, you’re not alone.
Understanding specific qualitative methods is one of the biggest stumbling blocks for PhD researchers - especially when the explanations are wrapped in layers of jargon.
So let’s strip it back and make it make sense.
If we’ve not met before, I’m Dr Elizabeth Yardley, and I help PhD students navigate qualitative research and finish their doctorates without getting stuck in the process.
What is constructivist grounded theory (in simple terms)?
At its core, constructivist grounded theory is a qualitative research approach where you develop theory directly from your data, rather than starting with a pre-existing theory and testing it.
That’s the key shift.
In many research designs, you begin with a theory and then collect data to test whether it holds up.
Grounded theory flips that.
You start with the data - interviews, observations, documents - and gradually build a theory from what you find.
A simple way to think about it is this:
Instead of starting with the picture on the puzzle box, you start with a pile of pieces and work out what the picture is as you go.
So what makes it constructivist?
This is where Kathy Charmaz’s approach becomes particularly important.
Earlier versions of grounded theory tended to treat data as something that existed “out there,” waiting to be discovered by a neutral researcher.
Charmaz challenges that idea.
In constructivist grounded theory, the theory is not something you uncover. It is something you construct.
That construction happens through the interaction between:
you (the researcher)
your participants
the context of the research
In other words, the data doesn’t simply exist in a pure, objective form. It is shaped by:
how participants tell their stories
the questions you ask
the way you interpret what you hear
This is one of the most important ideas to grasp:
The data is constructed, not just discovered.
Once that clicks, the whole approach starts to make much more sense.
The role of the researcher
This has big implications for your role as a qualitative researcher.
In more traditional approaches, the researcher is often positioned as a neutral observer.
In constructivist grounded theory, that’s not really possible.
You are part of the research process.
For example, when you interview someone, they are already interpreting their own experiences as they speak. Then you interpret what they’ve said. That means the final analysis is shaped by both of you.
Rather than trying to eliminate that influence, constructivist grounded theory asks you to acknowledge it and work with it.
This is why reflexivity becomes so important in qualitative research.
How constructivist grounded theory works (in practice)
Now let’s make this practical. What does this actually look like when you’re doing a qualitative PhD?
Starting with data, not theory
You begin by collecting data without trying to force it into a pre-existing framework.
You might be conducting interviews, analysing documents, or observing behaviour.
At this stage, you’re exploring.
You’re asking: What’s going on here? What seems to matter to people?
For example, if you’re researching how people experience career transitions, you might start to notice recurring ideas around uncertainty, identity, or confidence.
Those ideas come from the data - not from a theory you imposed at the start.
Coding: making sense of the data
As you work through your data, you begin coding.
Coding is simply a way of labelling segments of data so you can start to see patterns.
At first, your codes might be quite descriptive.
But as you move through the data, they become more conceptual. And importantly - they change.
This isn’t a linear process where you code everything once and move on.
You revisit, refine, combine, and sometimes discard codes as your understanding develops.
That evolving process is a core part of qualitative data analysis.
Constant comparison
One of the defining features of grounded theory is constant comparison.
You are continually comparing:
one interview with another
one code with another
one idea with another
You’re asking:
Is this the same as what I saw before?
Is it different?
What’s going on here?
This is how your analysis deepens over time.
Theoretical sampling
As patterns begin to emerge, your data collection becomes more focused.
You might realise that a particular idea needs further exploration.
So you go back and collect more data specifically related to that idea.
This is called theoretical sampling.
You are no longer just collecting data broadly - you are following the direction your analysis is taking you.
Memo writing
Alongside all of this, you write memos.
Think of these as your thinking space.
This is where you reflect on your codes, explore emerging ideas, make connections, and question your interpretations.
Memos are often where the early stages of your theory begin to take shape.
Why constructivist grounded theory works well for qualitative PhDs
This approach is particularly well suited to qualitative PhD research because it allows you to:
explore complex social experiences
stay close to participants’ perspectives
develop theory that is grounded in real-world data
It also aligns well with interpretivist thinking, where meaning is seen as something that is constructed rather than discovered.
Rather than forcing your data into existing frameworks, you are building something that reflects the complexity of what you’ve found.
The challenge (and the reality)
The flip side of this flexibility is that it can feel messy.
There isn’t always a clear step-by-step path.
You might find yourself thinking:
Am I doing this right?
When do I stop coding?
Is this actually becoming a theory?
That uncertainty is part of the process.
But it’s also why having a clear understanding of your methodology makes such a difference.
