Can a Narrative Research Study Have Only One Participant?

Can One Person's Story Provide Enough Evidence for Narrative Research?

You want to investigate how an experienced university teacher narrates changes in professional identity after decades of educational technology adoption. One participant has a particularly relevant professional trajectory and is willing to discuss significant experiences through extended interviews and reflective materials.

But can a study involving only one participant be academically defensible? Would reviewers consider the sample too small? Must you recruit additional teachers even when your research question concerns the development and meaning of one person's narrative?

The difficulty arises when expectations about sample size are transferred from other research designs without considering what narrative inquiry actually seeks to understand. A study centered on one person's story may offer substantial interpretive depth, but its adequacy depends on the research question, evidence, and analytical claims rather than the participant count alone.

When and How Single-Participant Narrative Research Can Be Defensible

Why Can Narrative Research Focus on One Participant?

Narrative research examines how experiences and meanings are constructed, organized, and communicated through stories. Its analytical purpose may involve understanding a particular narrative trajectory rather than identifying the frequency of experiences across a population.

Clandinin and Connelly's approach to narrative inquiry emphasizes the study of experience within temporal, social, and place-based contexts. Such inquiry can involve intensive engagement with an individual whose experiences provide a meaningful basis for investigating the research problem.

For example, a researcher might examine how one teacher narrates professional identity across major changes in educational technology, including the introduction of learning management systems, online teaching, and generative artificial intelligence.

The contribution would concern how that teacher constructs a narrative of professional continuity, disruption, or transformation. It would not establish how all teachers experience technological change.

The relevant methodological question is whether the individual account provides an appropriate basis for the intended narrative interpretation.

Does One Participant Mean There Is Only One Story?

No. One participant may contribute several stories, narrative episodes, or versions of an account across different encounters.

A teacher might recount an early experience with educational technology, a difficult transition to online instruction, and a recent encounter with generative AI. These accounts may be examined separately or interpreted as connected parts of a broader professional narrative.

Likewise, a single participant may contribute interviews, diaries, letters, reflective writing, photographs, or other materials that illuminate how a narrative develops.

Researchers should therefore distinguish the number of participants from the number of narrative materials and analytical units.

Defining the unit of analysis in narrative research helps clarify whether the study examines one developing narrative, several narrative episodes, or a particular story constructed across multiple sources.

When Is a Single-Participant Narrative Study Particularly Appropriate?

A single-participant design may be appropriate when the research question concerns a distinctive narrative trajectory, a particular transition, or the detailed construction of meaning within one person's account.

For example, a researcher may investigate how a teacher who experienced several major educational reforms narrates professional continuity across those changes.

Another study might examine how one student constructs a story of educational belonging after a significant institutional transition.

Such designs can support close attention to narrative structure, temporality, identity, and contextual relationships that might receive less attention in a broader comparative study.

However, the participant should not be selected merely because recruitment is difficult or the researcher has limited time. The justification must arise from the narrative question and the contribution the individual account can reasonably make.

What Makes One Narrative Analytically Significant?

Analytical significance does not necessarily require an exceptional or dramatic life story.

An apparently ordinary professional trajectory may illuminate how people construct continuity, normalize institutional expectations, or interpret gradual change.

Similarly, a narrative containing contradictions, uncertainty, or unresolved experiences may provide insight into how identity and meaning are negotiated.

The researcher should explain why the selected participant's circumstances are relevant to the phenomenon and how the resulting account can support meaningful interpretation.

For example, a teacher's long experience with educational technology may provide opportunities to examine how professional identity is narrated across several institutional transitions. The value lies in the analytical relationship between those experiences and the research question, not in the participant's presumed representativeness.

How Does Single-Participant Narrative Research Differ From a Single-Case Study?

A narrative study and a case study may both focus on one individual, but their primary analytical interests differ.

These approaches can overlap. A case study may incorporate narrative analysis, and narrative inquiry may examine a person within a particular institutional context.

The appropriate designation depends on whether the research question primarily concerns the story and its construction or the bounded case more broadly.

How Should You Select the Single Participant?

Selection should be purposive and justified by the participant's relevance to the narrative phenomenon.

For example, a study examining professional identity across successive educational technology changes may select a teacher who has experienced several relevant transitions and is willing to engage in reflective narrative conversations.

Selection criteria should not prescribe the story the participant is expected to tell. Requiring evidence of successful adaptation, for instance, could exclude narratives of resistance, uncertainty, or continuity.

The principles of selecting participants and stories for narrative research remain applicable even when the final sample contains one person.

The researcher should also explain why a comparative sample is not necessary for answering the particular question.

How Much Narrative Evidence Is Enough From One Participant?

There is no universal number of interviews, transcript pages, or narrative episodes that establishes adequacy.

The researcher should consider whether the evidence supports the intended interpretation, provides sufficient contextual understanding, and allows important narrative relationships to be examined.

For example, a study of a teacher's professional trajectory may require opportunities to discuss significant events, clarify temporal relationships, and explore how earlier experiences are interpreted from the present.

One extended interview may be adequate for some narrowly defined narrative questions. Other inquiries may benefit from repeated conversations or additional materials.

The decision about collecting narrative data in one interview or over time should follow the question rather than a predetermined methodological formula.

Can Multiple Interviews Strengthen a Single-Participant Study?

Repeated interviews may provide opportunities to clarify earlier accounts, revisit significant events, and examine how a participant's interpretations develop across encounters.

They can also support a more relational form of narrative inquiry in which stories are developed through ongoing conversations between researcher and participant.

However, repeated interviews do not simply reveal an increasingly complete or objectively accurate version of the participant's life.

Stories may change because circumstances change, memories are reconsidered, or the relationship between researcher and participant develops.

Such changes can be analytically meaningful. Researchers should document the conditions under which accounts were produced and avoid treating differences between interviews as automatic evidence of inconsistency or unreliability.

Can Documents, Diaries, and Photographs Strengthen the Analysis?

Yes, when they contribute relevant contextual or narrative evidence.

A teacher's reflective diary may reveal how professional interpretations changed over time. Photographs of teaching materials may prompt recollections of significant experiences. Institutional documents may help establish the circumstances surrounding narrated events.

These sources can enrich interpretation, but they should not be added merely to increase the quantity of data.

Researchers should examine the purpose, provenance, and context of each material. A retrospective interview and a diary written during an event may offer different kinds of evidence.

Using documents, diaries, photographs, and digital traces as narrative data also requires appropriate consent and attention to confidentiality.

How Do You Establish Rigor Without Multiple Participants?

Rigor in single-participant narrative research depends on methodological coherence, contextual depth, transparent interpretation, and ethical representation.

Researchers should explain how the narrative material was developed, which analytical approach was adopted, and how interpretations were supported by the account and its context.

Riessman's work demonstrates that narrative analysis can examine thematic content, structural organization, or the circumstances of storytelling. The appropriate analytical procedures depend on the research question.

Researchers should also consider alternative interpretations, contradictions within the narrative, and the influence of the researcher's questions and assumptions.

Additional sources may help contextualize the account, but their presence does not automatically establish validity.

The objective is not to prove that the participant's story represents everyone else's experience. It is to produce a credible interpretation of the narrative phenomenon within the study's stated scope.

Does One Participant Prevent Generalization?

A single-participant narrative study cannot ordinarily support statistical generalization to a broader population.

However, statistical representativeness is not the principal objective of many narrative approaches.

A carefully contextualized narrative may contribute conceptual understanding, illuminate possibilities, challenge assumptions, or help readers consider similarities and differences with other circumstances.

Such contributions should not be confused with claims about prevalence or typicality.

For example, one teacher's account may illuminate how professional identity can be narrated through experiences of technological change. It cannot establish that all teachers follow the same trajectory.

Researchers should provide sufficient contextual information for readers to evaluate the relevance and possible transferability of the interpretation while avoiding unsupported population-level conclusions.

Can One Participant Provide Contradictory or Multiple Perspectives?

Yes. A participant's narrative may contain tensions, competing interpretations, or changes in how experiences are understood.

For example, a teacher may describe generative AI as both a professional opportunity and a threat to established assessment practices.

These positions need not be treated as mutually exclusive or as evidence that the participant is unreliable.

Narrative analysis can investigate how apparently contradictory meanings coexist within a developing professional identity.

However, one participant cannot provide independent perspectives from all relevant social positions. If the question requires comparing how different groups narrate an institutional event, a single-participant design may be insufficient.

What Ethical Risks Are Particular to Single-Participant Narrative Studies?

Confidentiality can be especially difficult when the study concerns one identifiable professional trajectory or a distinctive life event.

Even if the participant's name is replaced with a pseudonym, readers familiar with the setting may recognize the person from career details, institutional roles, or significant events.

Researchers should discuss foreseeable identification risks, the intended publication of narrative material, and the practical limits of anonymity.

They should also consider how the account describes colleagues, family members, students, or other people who have not consented to participate.

In relational narrative inquiry, the researcher's responsibility extends to how stories are interpreted and represented, particularly when participants share sensitive experiences over repeated encounters.

Participant review may be useful where appropriate, but it does not automatically resolve all ethical or interpretive disagreements.

When Is One Participant Not Enough?

A single-participant design may be inappropriate when the research question requires comparison across people, social positions, or narrative contexts.

For example, a study asking how early-career and experienced teachers construct contrasting narratives of AI adoption would ordinarily require accounts from both groups.

Similarly, a question about competing institutional narratives may require evidence from several participants or organizational materials.

One participant may also be insufficient when the available account lacks the contextual depth or narrative material necessary to address the question.

Researchers should not defend an inadequate design by arguing that narrative research always permits one participant. The number must be justified by the particular inquiry.

How Should You Report a Single-Participant Narrative Study?

The methodology section should explain why the participant was selected, how the narrative material was developed, and why one participant was appropriate for the research question.

Describe the narrative tradition, data sources, number and nature of research encounters, analytical procedures, and relevant contextual information.

Explain how the researcher's relationship with the participant influenced the development and interpretation of the account.

Finally, state the scope of the findings and acknowledge limitations concerning representation, contextual knowledge, and transferability.

A strong justification should demonstrate methodological fit rather than apologize for the sample size or claim that narrative research is exempt from questions of evidence adequacy.

Designing a Narrative Study Around One Teacher's Professional Story

The single-participant design is defensible because the research question specifically concerns the construction of one professional narrative and the evidence supports detailed interpretation.

The three interviews are illustrative rather than a methodological requirement. Another narrative question might justify a different number of encounters or different sources of evidence.

Common Misconceptions About Single-Participant Narrative Research

How Should You Decide Whether One Participant Is Sufficient?

Begin by determining whether the research question concerns a particular narrative or requires comparison across participants.

If the question can be answered through intensive analysis of one situated account, a single-participant design may be appropriate. If the question requires understanding differences among groups or competing perspectives, additional participants or narrative sources may be necessary.

In your proposal, justify the single-participant design through the narrative question and the intended analytical depth. In the final report, demonstrate how the evidence supports the interpretation and where its limits lie.

A defensible narrative study does not need a large sample to appear rigorous. It needs a coherent explanation of why the selected narrative matters and what can reasonably be learned from it.
