Should Narrative Data Be Collected in One Interview or Over Time?

Can One Interview Capture a Narrative, or Must You Follow Participants Over Time?

You want to investigate how university teachers narrate their professional experiences with generative artificial intelligence. You could conduct one extended interview asking participants to recount significant events, turning points, and changes in their teaching identities. Alternatively, you could interview the same teachers several times as their experiences continue to develop.

Would the second approach produce stronger narrative research? Can a single retrospective interview adequately represent experiences unfolding across several years? And if participants tell different versions of their stories during subsequent interviews, should those differences be treated as inconsistencies or as meaningful narrative developments?

These decisions affect more than the amount of data collected. They determine whether the study examines a story told at a particular moment, a narrative developed through repeated encounters, or the changing ways participants interpret experiences as events unfold.

Why Does Interview Timing Matter in Narrative Research?

Narrative research examines stories as situated constructions of meaning. A story told today about an event five years ago is not simply a recording of that earlier event. It is an account constructed from the narrator's present circumstances, memories, relationships, and understanding of what happened.

Connelly and Clandinin's work on narrative inquiry emphasizes the temporal character of experience. Narrative accounts can connect remembered pasts, present circumstances, and anticipated futures, even when the research involves only one encounter.

Interview timing matters because the circumstances of storytelling influence what participants emphasize and how they interpret their experiences.

A teacher interviewed shortly after an institutional AI policy is introduced may describe uncertainty about its implications. The same teacher interviewed after a semester of implementation may reinterpret that uncertainty as an important professional turning point or as an issue that ultimately had little significance.

Neither account must be considered the more authentic version. Each provides evidence about how experience is narrated from a particular temporal position.

When Is One Narrative Interview Sufficient?

One in-depth interview may be appropriate when the research question concerns a retrospective narrative that participants can meaningfully construct during a single encounter.

For example, a researcher might ask how experienced teachers narrate their transition from conventional classroom teaching to technology-supported instruction.

Participants may recount earlier experiences, describe significant events, and explain how those experiences contribute to their present professional identities.

The interview can provide substantial narrative material when participants have opportunities to develop extended accounts and the researcher attends to the temporal and contextual relationships within them.

However, one interview does not necessarily provide a complete life history or establish what participants would have said at earlier points in time. The resulting analysis concerns a narrative constructed in the circumstances of that interview.

When Are Repeated Narrative Interviews More Appropriate?

Repeated interviews are particularly useful when the research question concerns an unfolding experience, changing interpretation, or the development of narrative identity over time.

A study investigating how newly appointed teachers construct professional identities during their first academic year might benefit from interviews at several points during that period.

Early interviews could explore expectations and initial encounters. Later interviews could examine how participants reinterpret those experiences after encountering new professional responsibilities.

Repeated engagement may also allow participants to revisit earlier accounts, elaborate on events, or introduce experiences that had not previously seemed important.

Nevertheless, multiple interviews should not be treated as a universal requirement. Their value depends on whether changes between encounters are analytically relevant to the question.

What Is the Difference Between Retrospective and Longitudinal Narrative Research?

Retrospective narrative research investigates accounts of experiences that have already occurred. Longitudinal narrative research examines narratives or experiences across multiple points in time.

The distinction concerns the temporal organization of the research, not simply the length of the story being told.

Longitudinal research can also include retrospective questions, and a single interview may contain extensive temporal reflection. Researchers should therefore distinguish the time represented within a story from the time over which research encounters occur.

Does One Interview Mean the Study Cannot Examine Chronology?

No. A participant can construct a detailed account of events extending across many years during one interview.

The researcher may examine how the narrator establishes beginnings, identifies significant moments, connects events, and interprets changes in identity.

However, the account remains a retrospective construction. Its chronology should not automatically be treated as a verified sequence of historical events.

For example, a teacher may describe the introduction of generative AI as the moment that transformed their professional practice. Documentary evidence or earlier reflections might indicate that important changes began before that event.

The difference need not invalidate the narrative. It may reveal how the teacher presently constructs the significance of AI within a broader professional story.

The analytical importance of chronology and turning points should guide whether additional temporal evidence is needed.

Can Repeated Interviews Reveal How Narratives Change?

Yes. Repeated interviews allow researchers to examine how participants reconstruct experiences as circumstances and interpretations change.

For example, a teacher may initially narrate AI adoption as an institutional obligation. After experimenting with AI-supported teaching, the teacher may describe the same transition as an opportunity for professional development.

The researcher can investigate what changed in the participant's circumstances and how the narrative was reconstructed.

However, researchers should avoid assuming that a later account is necessarily more accurate or complete.

Changes in storytelling may reflect new experiences, shifts in identity, altered relationships with the interviewer, or different understandings of what the research conversation requires.

Longitudinal narrative analysis should attend to these possibilities rather than simply comparing statements for factual consistency.

What Is the Difference Between Repeated Interviews and Longitudinal Narrative Inquiry?

Conducting several interviews does not automatically make a study longitudinal.

A researcher might conduct three interviews within one week to develop a detailed retrospective account. Although the study includes repeated encounters, it may not investigate narrative development across a meaningful period.

Longitudinal inquiry requires a temporal rationale. The research design should identify why particular intervals or stages matter to understanding the phenomenon.

For example, interviews before, during, and after an institutional AI policy implementation may provide opportunities to examine how narratives develop in relation to identifiable events.

By contrast, scheduling three interviews merely because three seems methodologically substantial provides little justification for a longitudinal designation.

How Should You Decide the Number and Timing of Interviews?

There is no universally appropriate number of narrative interviews or interval between them.

Interview scheduling should reflect the temporal characteristics of the phenomenon. A study of first-year teacher identity may benefit from encounters distributed across an academic year. A study of a short institutional transition may require a more concentrated schedule.

Researchers can identify relevant milestones, anticipated events, and opportunities for reflection when planning the interview sequence.

They should also consider participant availability, cumulative burden, research resources, and the possibility that unexpected events may require adjustments.

The schedule may be refined when analytically justified, subject to applicable ethics requirements.

Timing should be reported transparently so readers can understand the circumstances in which each narrative was constructed.

Should Every Interview Ask the Same Questions?

Not necessarily. The appropriate interview structure depends on whether the study prioritizes comparison across encounters, development of individual narratives, or the exploration of emerging experiences.

Repeated interviews may revisit some common questions to examine how interpretations change. They may also introduce new prompts based on events occurring between encounters.

For example, an initial interview might invite a teacher to narrate expectations about using generative AI. A later interview could ask how subsequent experiences affected those expectations.

Researchers should avoid mechanically repeating questions when doing so prevents participants from developing accounts of unexpected experiences.

At the same time, documenting changes to interview prompts can help explain how the researcher's developing interests influenced later narratives.

How Do Interviews Become Narrative Rather Than Merely Question-and-Answer Data?

Narrative interviews should provide opportunities for participants to construct meaningful accounts rather than only supply brief responses to predetermined categories.

Open invitations such as "Tell me about a time when your understanding of AI in teaching changed" may encourage participants to connect events, circumstances, and interpretations.

Follow-up questions can explore what happened before and afterward, why an event became significant, and how participants understand it from their present position.

However, researchers should not require every account to follow a conventional chronological structure. Fragmented or nonlinear storytelling may be relevant to the analytical purpose.

Riessman's work emphasizes that narratives are situated forms of communication. The interviewer's questions and responses can influence how stories are developed.

Consequently, narrative interviewing requires attention to both the account and the circumstances of its production.

Can Diaries and Other Materials Supplement Narrative Interviews?

Yes. Diaries, reflective journals, letters, photographs, digital communications, and other materials may provide evidence from different moments or contexts.

For example, a teacher's reflective journal written during an AI policy transition may reveal interpretations that differ from those offered in a retrospective interview months later.

These differences may help the researcher examine how experiences are reconstructed over time.

However, supplementary materials are not automatically more authentic than interviews. Diaries are also situated accounts shaped by their intended audience, purpose, and circumstances of production.

Researchers should justify the use of documents, diaries, photographs, and digital traces as narrative data according to their contribution to the question.

How Does Interview Timing Affect the Unit of Analysis?

When a study uses one interview, the analytical unit may be a complete narrative account or particular stories constructed within that encounter.

In repeated interviews, the researcher may examine each account separately or interpret the developing narrative across encounters.

For example, a longitudinal study might investigate how one teacher constructs professional identity differently at the beginning and end of an academic year.

The researcher must decide whether the principal focus is each interview narrative, the overall trajectory, or particular episodes appearing across encounters.

This decision should be consistent with the unit of analysis in narrative research.

Without such clarification, researchers may treat differences between interviews as independent themes when their significance depends on the developing narrative relationship.

How Do You Analyze Narratives Collected at Several Time Points?

Longitudinal narrative analysis may involve examining each account within its original context before investigating continuity and change across encounters.

Researchers can consider which events participants emphasize, how earlier experiences are reinterpreted, whether anticipated futures change, and how narrative identities are reconstructed.

For example, an instructor may initially describe AI as a threat to professional expertise, later present experimentation as necessary adaptation, and eventually narrate selective use as an expression of professional judgment.

The analysis should not automatically impose a linear progression from resistance to acceptance. Participants may return to earlier positions, express contradictory interpretations, or construct narratives without clear resolution.

Maintaining the contextual integrity of each account is important when preserving individual stories during cross-time analysis.

What Happens When Participants Withdraw From a Longitudinal Study?

Repeated interviews create the possibility of participant attrition. Participants may become unavailable, lose interest, experience changing circumstances, or withdraw consent.

Researchers should establish appropriate withdrawal procedures during ethical planning and avoid pressuring participants to remain involved.

When a participant leaves, the researcher should determine what use of previously collected material is permitted under the consent arrangements and applicable requirements.

Incomplete longitudinal narratives may still provide meaningful evidence, but they should not be represented as though the intended sequence of encounters was completed.

Attrition may also affect the range of narratives available for comparison. Researchers should explain these limitations rather than treating missing encounters as analytically inconsequential.

Does Repeated Contact Create Additional Ethical Responsibilities?

Yes. Longitudinal narrative research can involve developing relationships in which participants share increasingly personal experiences.

Researchers should consider cumulative participant burden, changing consent expectations, confidentiality, and the potential emotional consequences of repeatedly discussing difficult events.

Participants may also disclose information about colleagues, students, or family members who are not research participants.

The researcher should maintain clear boundaries concerning the purpose of the research relationship and avoid assuming that familiarity constitutes permission to collect or publish additional information.

Relational ethics is particularly important in narrative inquiry because stories may be developed collaboratively through repeated encounters.

When Is One Interview Not Enough?

One interview may be insufficient when the question requires examining how narratives change across time or when the initial account lacks necessary contextual depth.

For example, a researcher asking how teachers construct professional identities throughout their first year of AI policy implementation would have difficulty directly examining narrative development if all interviews occurred before implementation began.

A retrospective interview after the year ended could provide an account of the transition, but it would not show how the teacher narrated experiences at earlier points.

Researchers should distinguish these forms of evidence and select the design that fits the intended claims.

One interview may also be insufficient when participants cannot meaningfully develop the relevant account within the available time. Additional voluntary encounters may help clarify significant events or relationships.

When Are Multiple Interviews Unnecessary?

Repeated interviews may be unnecessary when the research question concerns a clearly bounded retrospective story that can be adequately examined through one encounter.

For example, a study might investigate how experienced instructors narrate a particular professional turning point associated with the transition to online teaching.

If participants provide sufficiently contextualized accounts and the analysis does not require examining narrative development across separate encounters, additional interviews may contribute relatively little.

Researchers should not increase participant burden simply to satisfy an assumed standard of methodological rigor.

Interview adequacy should be judged through the analytical purpose and the evidence available, not through the number of scheduled conversations.

Choosing Between One Interview and Longitudinal Narrative Interviews

Neither design is automatically superior. Study A is appropriate for a question about present retrospective storytelling, while Study B is better aligned with a question about narrative development over time.

The three-interview schedule in Study B is illustrative rather than a prescribed standard. The appropriate timing would depend on the relevant events, research question, and participants' circumstances.

Common Misconceptions About Narrative Interview Timing

How Should You Choose Your Narrative Interview Schedule?

Identify whether your question concerns a story constructed at one moment or the development of narratives across multiple moments. This distinction should determine the temporal structure of data collection.

In your methodology section, justify not only the number of interviews but also their timing and analytical purpose. Explain what each encounter was intended to contribute and how the resulting narratives were interpreted.

A single interview can support a substantial narrative study. Repeated interviews become necessary when the temporal development of narratives is central to the knowledge the study seeks to produce.
