Semi-structured interview

A semi-structured interview is a qualitative research method characterized by the use of a flexible interview guide with predetermined open-ended questions, enabling interviewers to explore participants' thoughts, feelings, beliefs, and experiences in depth while allowing adaptability in question sequencing and follow-up probes.^[1] This approach balances the structure of predefined topics with the conversational freedom of unstructured interviews, facilitating a purposeful dialogue that uncovers contextual and subjective insights.^[2]^[3] Key characteristics of semi-structured interviews include their thematic focus, where the interviewer maintains an informal yet directed "conversation with a purpose," emphasizing active listening, empathy, and iterative interaction to build rapport and elicit nuanced responses.^[2]^[1] Unlike fully structured interviews, which rely on fixed responses, or unstructured ones, which lack a guide, this method permits real-time adjustments to probe deeper into emerging themes, often conducted face-to-face or virtually with small samples of 8–30 participants selected purposively for diversity.^[4]^[3] The advantages of semi-structured interviews lie in their ability to generate rich, exploratory data on complex social, behavioral, or policy-related phenomena, providing more depth than surveys while ensuring consistency across interviews through the guide.^[1]^[2] They are particularly effective for triangulating quantitative findings, validating other data sources, and complementing mixed-methods studies, though they require rigorous analysis—such as thematic coding and cross-referencing—to ensure trustworthiness and mitigate interviewer bias.^[4]^[3] Commonly applied in fields like health services, social sciences, education, and policy evaluation, semi-structured interviews help researchers understand implementation processes, participant viewpoints, and contextual effects, as seen in studies exploring service delivery or program reception.^[1]^[3] Methodological frameworks, such as the 7S CARS-SID approach, guide their design, conduct, analysis, and reporting to enhance rigor, including steps like developing the interview guide, sampling, transcription, and drawing context-specific conclusions.^[4]

Definition and Characteristics

Definition

A semi-structured interview is a qualitative research method for data collection that employs a flexible interview guide featuring open-ended questions to systematically explore predetermined themes, while permitting the interviewer to adapt and incorporate emergent topics arising from the dialogue.^[1] This technique facilitates verbal interaction between the interviewer and participant, aiming to elicit detailed insights into the respondent's experiences, perspectives, and worldviews.^[3] Unlike more rigid interviewing approaches, semi-structured interviews strike a balance between structured coverage of key topics—via an aide-mémoire or question framework—and the fluidity of natural conversation, enabling the pursuit of unanticipated details and nuanced viewpoints without imposing a fixed sequence or wording.^[5] In the social sciences, this method is commonly applied in exploratory studies, such as policy analysis or grounded theory development, where depth and contextual richness are essential beyond what standardized responses can offer.^[3] It serves as a middle ground between structured interviews, which adhere to a strict script, and unstructured interviews, which proceed without a predefined guide.^[6]

Key Features

Semi-structured interviews are characterized by their hybrid nature, which integrates a predetermined framework of topics or questions with the flexibility to adapt during the conversation, ensuring consistency across multiple interviews while allowing for the emergence of unexpected insights. This balance enables researchers to maintain focus on core themes while pursuing participant-led explorations, distinguishing the method from more rigid formats.^[7]^[8] A primary feature is the flexibility in question sequencing and probing, where interviewers can reorder topics or introduce follow-up probes based on the participant's responses, without adhering to a strict script. This adaptability permits the interviewer to follow natural leads in the dialogue, such as elaborating on unanticipated details, thereby enriching the data collected. For instance, probes like "Can you tell me more about that?" encourage deeper responses while keeping the interview aligned with the overall guide.^[7]^[8]^[9] The method relies heavily on open-ended questions that emphasize "how" and "why" aspects of experiences, designed to elicit detailed, narrative responses rather than brief answers. These questions revolve around a set of core topics outlined in an interview guide, fostering comprehensive accounts from participants and allowing for the integration of both planned and emergent content. This approach supports in-depth qualitative inquiry by prioritizing participant perspectives over standardized replies.^[7]^[8]^[5] In terms of duration and format, semi-structured interviews are generally conducted one-on-one and last 30-60 minutes, providing sufficient time for thorough discussion without overwhelming participants. They can occur in-person, via telephone, or virtually through platforms like video calls, adapting to logistical needs while preserving the interactive essence of the method.^[7]^[6]^[8]

Historical Development

The semi-structured interview emerged as a key qualitative method in the mid-20th century, building on efforts to balance flexibility and focus in social science inquiry. A foundational precursor was the "focused interview," developed by Robert K. Merton and Patricia L. Kendall in 1946, which employed a topic guide to explore participants' reactions to predefined stimuli—such as media content—while permitting conversational deviations to uncover deeper insights. This approach addressed the need for structured yet adaptable data collection in studying social and psychological responses, marking an early shift toward semi-structured techniques in sociology.^[10] In 1954, Herbert H. Hyman and colleagues described interviewing in social research as a conversational technique inherent to social science methodologies, emphasizing its role in fostering natural dialogue to elicit reliable responses without the constraints of overly prescriptive formats. This characterization highlighted the method's utility in navigating the complexities of human communication, positioning it as a versatile tool for qualitative exploration beyond mere fact-gathering.^[11] During the 1950s to 1970s, semi-structured interviews gained prominence through their alignment with interpretivist, interactionist, constructionist, feminist, and psychoanalytic paradigms, which sought to prioritize participants' lived experiences, social constructions of reality, and power dynamics in knowledge production. These traditions, prevalent in sociology and anthropology, favored the method's capacity to generate situated, interactive data that illuminated subjective interpretations rather than objective metrics.^[5] The method's origins were particularly driven by critiques of rigid surveys and structured questionnaires, which dominated earlier quantitative research but often overlooked the nuanced, context-dependent nature of human subjectivity in fields like sociology and anthropology. By introducing flexibility—such as probes and follow-ups—semi-structured interviews enabled researchers to probe deeper into personal narratives and cultural meanings, filling a critical gap in capturing experiential data that standardized tools could not.^[12]

Evolution and Modern Adaptations

Following the establishment of semi-structured interviews as a core method in social sciences during the mid-20th century, their usage expanded significantly from the late 1980s onward, particularly within qualitative research paradigms. By the 1990s, these interviews gained prominence in key handbooks and texts, which highlighted their flexibility for exploring nuanced participant perspectives while allowing integration with quantitative elements in mixed-methods studies.^[13] For instance, Michael Quinn Patton's influential 1990 work on qualitative evaluation methods emphasized semi-structured approaches as a balanced strategy for in-depth inquiry without rigid constraints, contributing to their widespread adoption across disciplines like education and health sciences. This period marked a shift from viewing semi-structured interviews merely as a technique to recognizing them as a standalone method, with proliferation evident in the diversification of applications and the production of specialized guidelines.^[13] In recent years, particularly from 2020 to 2025, semi-structured interviews have adapted to technological and global challenges, most notably through a rapid transition to virtual formats facilitated by video conferencing platforms like Zoom and Microsoft Teams. This shift was accelerated by the COVID-19 pandemic, which necessitated remote data collection to maintain research continuity while minimizing health risks, enabling global participation without geographical barriers.^[14] Concurrently, integration with digital tools has enhanced efficiency, including high-quality recording software for capturing non-verbal cues and automated transcription services powered by artificial intelligence, such as Otter.ai or OpenAI's Whisper, which streamline initial data processing and reduce manual labor.^[14]^[15] These adaptations have not only preserved the method's core flexibility but also improved accessibility and ethical considerations, such as informed consent in digital environments.^[16] Key milestones underscore this evolution's institutionalization. In 2019, an article published in Family Medicine and Community Health promoted semi-structured interviews as a practical tool for primary care research, emphasizing their feasibility for clinicians to gather patient insights on complex health behaviors.^[1] Similarly, in 2023, Sciences Po's HAL repository issued reports framing semi-structured interviews within policy evaluation frameworks, advocating their use for assessing implementation and stakeholder objectives in public administration.^[3] These developments reflect the method's maturation into a versatile, technology-enhanced approach integral to contemporary empirical inquiry.

Comparison with Other Interview Methods

Structured Interviews

A structured interview is a data collection method in which the interviewer follows a predetermined script consisting of a fixed sequence of questions, typically closed-ended, to elicit standardized responses from participants. These questions are designed in advance and presented in the same order to every respondent, often incorporating predefined response options such as yes/no answers, multiple-choice selections, or rating scales like Likert scales, which measure attitudes or opinions on a numerical continuum (e.g., from "strongly agree" to "strongly disagree"). This format ensures that the interview closely resembles an oral questionnaire, minimizing variations in wording or probing that could influence answers.^[17] The primary purpose of structured interviews is to achieve high levels of reliability and comparability across responses, facilitating quantitative analysis and statistical generalization in research studies. They are particularly common in large-scale surveys, epidemiological investigations, and social science research where the goal is to gather measurable data from diverse populations for hypothesis testing or trend identification. By enforcing uniformity, structured interviews support replicable results that can be aggregated and analyzed using tools like frequency distributions or regression models.^[18] Key characteristics of structured interviews include minimal interviewer discretion, with little to no allowance for follow-up questions or deviations from the script, which emphasizes standardization to reduce potential biases introduced by the interviewer's personal style, expectations, or interpretations. This rigidity contrasts with the flexibility of semi-structured interviews, where interviewers can adapt questions based on responses. Overall, the approach prioritizes objectivity and efficiency, making it ideal for scenarios requiring consistent data across many participants to minimize measurement error.^[17]^[18]

Unstructured Interviews

Unstructured interviews represent the most flexible approach within qualitative interviewing methods, characterized by the absence of a predefined set of questions or a rigid script. Instead, the interaction unfolds as a natural, conversational exchange where the interviewer poses spontaneous follow-up questions based on the participant's responses, often guided only by broad topics or an informal agenda to maintain focus. This format, sometimes referred to as informal conversational interviewing, prioritizes the participant's narrative flow and allows for the emergence of unanticipated insights without imposing the researcher's preconceived categories.^[19]^[6] The primary purpose of unstructured interviews is to facilitate a deep exploration of participants' personal experiences, perceptions, and social realities, making them particularly suitable for exploratory phases of research where the goal is theory-building or generating hypotheses. By enabling respondents to express themselves freely at their own pace, these interviews uncover nuanced, context-rich details that might otherwise remain hidden in more directive formats, such as when studying complex behaviors in ethnographic settings or initial investigations into unfamiliar phenomena.^[19]^[17] This open-ended nature positions unstructured interviews at one extreme of the interviewing spectrum, contrasting with semi-structured approaches that incorporate a flexible guide for greater balance between depth and consistency.^[6] Key traits of unstructured interviews include their heavy reliance on the interviewer's expertise to establish rapport, actively listen, and subtly direct the conversation without leading the participant, demanding skills in real-time adaptation and ethical probing. While this yields rich, detailed qualitative data that captures the complexity of lived experiences, the lack of standardization often results in less directly comparable responses across participants, complicating aggregation and requiring supplementary methods like field notes for validation.^[19]^[17] Despite these challenges, the method's versatility supports its use in diverse fields, from anthropology to journalism, where holistic understanding trumps uniformity.^[6]

Preparation and Conducting

Developing the Interview Guide

The development of an interview guide is a foundational step in preparing for semi-structured interviews, enabling researchers to systematically explore research objectives while allowing conversational flexibility. This guide acts as a roadmap, outlining key topics and questions without imposing a rigid script, thereby facilitating the emergence of unanticipated insights central to the method's flexibility. According to established qualitative research protocols, the process emphasizes iterative refinement to ensure the guide effectively captures rich, participant-driven data aligned with the study's aims.^[20] The core components of an interview guide include a curated set of typically 6 to 12 open-ended questions, strategically grouped by thematic areas to provide logical progression and comprehensive coverage of the research domain.^[21] For instance, questions might be organized under themes such as participant background, experiences, and perceptions, with examples like "Describe your daily routines in this role" under a workflow theme. To deepen responses, the guide incorporates probes—follow-up prompts for clarification or elaboration, such as "What challenges did you encounter?" or "How did that affect your decisions?"—which encourage detailed narratives without directing the participant's viewpoint. This structure ensures the guide remains focused yet adaptable, kept concise for practicality during interviews.^[22]^[23] Key design principles guide the creation of the interview guide to enhance its reliability and validity. Questions must align closely with the research objectives, deriving directly from the study's conceptual framework to target essential data while avoiding tangential inquiries. To prevent bias, phrasing should steer clear of leading language, favoring neutral constructions like "What are your thoughts on..." over suggestive ones such as "Don't you agree that...". Clarity is paramount, with short, jargon-free wording tested for accessibility across participant demographics. Pilot testing forms a crucial validation phase, involving 2-3 trial interviews with individuals similar to the target population to evaluate question flow, comprehension, and duration; revisions based on this feedback refine the guide, often reducing ambiguity or reordering for better rapport-building.^[22]^[24] Supporting tools within the interview guide help maintain focus amid the method's inherent openness. Topic lists serve as high-level outlines of discussion areas, providing quick references to ensure all objectives are addressed without constraining spontaneous dialogue. Visual aids, such as flowcharts or mind maps of themes, can be included for complex topics, aiding both the interviewer in navigation and participants in articulating connections between ideas. These elements collectively uphold the semi-structured balance, promoting structured yet dynamic data collection.^[23]

Execution of the Interview

The execution of a semi-structured interview begins with the interviewer building rapport to foster a comfortable environment for the participant. This initial step typically involves starting with casual, non-threatening conversation, such as discussing shared experiences or the participant's background, to establish trust and encourage open dialogue.^[1] Rapport-building helps transition smoothly into the core topics without making the participant feel interrogated.^[25] Once rapport is established, the interviewer loosely follows the prepared guide—referencing it from the prior development phase—while allowing flexibility in question order and phrasing to align with the participant's narrative flow. Active listening forms the foundation of this process, with the interviewer employing techniques like nodding, maintaining eye contact, using brief affirmations such as "Yes..." or allowing periods of silence to signal attentiveness and invite further elaboration.^[1] To deepen responses, probes are integrated naturally, including echoing statements (e.g., "Right, so it was hard..."), expansion requests (e.g., "Tell me more about that"), or clarification questions (e.g., "What do you mean by...?").^[1] These probes, often phrased as "Why is that?" or "How did that make you feel?", help uncover nuanced insights without leading the participant.^[25] Interviews are generally conducted in a private, quiet setting to minimize distractions and ensure confidentiality, typically lasting 30–90 minutes to balance depth with participant comfort.^[26] Audio recording is commonly used with participant consent to capture responses accurately, though the interviewer takes contemporaneous notes as a backup.^[1] Throughout the session, the interviewer's role emphasizes adaptability, responding to emergent themes by reordering or expanding on topics as needed, while managing time to ensure coverage of essential guide elements without rushing. A non-judgmental, warm demeanor supports this, allowing the conversation to meander productively before gently steering back to key areas if necessary.^[25] This flexible yet structured approach distinguishes semi-structured interviews by prioritizing participant-driven content over rigid scripting.^[1]

Advantages and Limitations

Benefits

Semi-structured interviews are particularly valued for their ability to elicit depth and richness in qualitative data, enabling researchers to explore participants' experiences, perceptions, and contexts in detail beyond surface-level responses. By incorporating open-ended questions and probes, these interviews facilitate nuanced insights into complex phenomena, capturing verbal and non-verbal cues such as tone, pauses, or expressions that enrich the interpretive analysis.^[1] This approach allows for multilayered understandings of participants' viewpoints, making it especially effective for uncovering underlying motivations or subtle dynamics in social interactions.^[27] A key strength lies in balancing comparability with flexibility, as the predefined interview guide ensures consistent coverage of core topics across participants while permitting deviations to pursue emergent themes or clarifications. This structure supports cross-case analysis by standardizing key questions, yet the adaptability fosters unique, context-specific responses that enhance data validity and reliability, particularly in larger samples where flexible coding can be applied systematically.^[27] Unlike more rigid formats, this hybrid nature allows researchers to maintain focus on research objectives without constraining the natural flow of dialogue, thereby improving the overall coherence of findings.^[1] The versatility of semi-structured interviews makes them suitable for a range of exploratory studies and sensitive topics, where building rapport is crucial for obtaining candid disclosures. They excel in generating open-ended, qualitative data that can inform theory development or hypothesis refinement, adapting to diverse participant backgrounds or evolving research questions during the process.^[28] This adaptability positions them as a robust tool for initial investigations into understudied areas, promoting trust and encouraging detailed personal narratives without the constraints of fully scripted interactions.^[1]

Challenges

Semi-structured interviews, while offering flexibility in data collection, present several notable challenges that can impact their reliability and practicality in qualitative research. One primary limitation is their time-intensive nature, which demands significant preparation, execution, and post-interview processing. Conducting these interviews requires skilled interviewers who possess strong facilitation abilities, such as active listening, effective probing, and sensitivity to participant cues, to navigate the balance between structure and adaptability without introducing inconsistencies.^[1] Inexperienced interviewers may struggle with these demands, leading to suboptimal data quality.^[29] Furthermore, the analysis phase is particularly laborious, as transcribing audio recordings can be extremely time-consuming and costly if outsourced, often extending the overall research timeline considerably.^[1] Another significant challenge arises from the risk of subjectivity and interviewer bias, which can compromise the consistency and validity of the collected data. The semi-flexible format allows interviewers to probe and follow up based on responses, but this discretion introduces potential for personal biases to influence question phrasing, emphasis, or interpretation, potentially leading to varied data across participants.^[1] For instance, inadequate probing or insensitive questioning may elicit incomplete or skewed responses, undermining the method's goal of capturing nuanced insights.^[1] Linguistic or cultural barriers can exacerbate this issue, as misunderstandings during the interview may result in data loss or altered meanings upon translation, further affecting reliability.^[27] Scalability poses a further limitation, making semi-structured interviews less suitable for studies requiring large sample sizes compared to more rigid structured methods. The individualized nature of each interview, including scheduling, rapport-building, and adaptive questioning, renders it inefficient and resource-prohibitive to scale up to hundreds of participants; for example, conducting 400 or 500 such interviews is described as a daunting task due to the prohibitive time and logistical demands.^[30] Access challenges, such as obtaining permissions or accommodating participant availability, compound this issue, often restricting studies to smaller cohorts and limiting generalizability.^[31] As a result, while effective for in-depth exploration, this method may not align well with research objectives demanding broad, quantitative-like coverage.^[30]

Applications Across Fields

In Research and Academia

Semi-structured interviews are extensively employed in academic research across disciplines such as sociology, psychology, and education to delve into participants' attitudes, experiences, and subjective interpretations of complex phenomena. In sociology, these interviews enable researchers to capture nuanced social dynamics and cultural practices through a balance of predetermined questions and emergent probes, facilitating deeper insights into community interactions and societal structures.^[5] Similarly, in psychology, they support the exploration of individual mental processes and behavioral patterns by allowing flexibility to pursue unanticipated responses while maintaining focus on key themes like emotional responses or cognitive frameworks. In education research, semi-structured interviews are particularly valuable for examining stakeholders' perspectives on learning environments, teaching methodologies, and policy impacts, often revealing hidden challenges in classroom experiences.^[32] Notable applications include policy evaluations and oral history projects, where semi-structured interviews provide contextual depth to scholarly inquiries. For instance, in public policy analysis, they are used to assess implementation processes and beneficiary perceptions, as demonstrated in a 2022 evaluation of Colombia's Jornada Unica educational program, which incorporated 31 semi-structured interviews with officials and educators alongside focus groups and observations to clarify policy objectives and outcomes.^[3] In oral history research, these interviews offer a guided yet adaptable format to elicit personal narratives and historical reflections, ensuring comprehensive coverage of life events while accommodating spontaneous recollections.^[18] Additionally, in mixed-methods studies, semi-structured interviews serve to triangulate qualitative data with quantitative findings, strengthening the robustness of results by cross-verifying patterns across diverse sources.^[33] Within academia, semi-structured interviews excel in generating hypotheses and supporting theory-building by yielding rich, inductive data that can refine or expand conceptual models. Their flexibility allows researchers to identify emergent themes during data collection, which in turn inform preliminary hypotheses for further testing or theoretical development.^[34] This approach is especially beneficial in exploratory studies, where the interviews' structure guides inquiry while permitting adaptations that uncover underlying mechanisms, ultimately contributing to more grounded and iterative theoretical advancements.

In Professional Settings

Semi-structured interviews are widely applied in market research to explore consumer behaviors and preferences through a blend of predetermined questions and flexible follow-ups, allowing researchers to uncover nuanced insights while maintaining comparability across responses. In this field, they facilitate exploratory studies, particularly in B2B contexts, where hybrid questionnaires combine closed-ended quantitative items with open-ended probes to address diverse respondent perspectives efficiently.^[35] In human resources (HR) recruitment, semi-structured interviews serve as a key tool for evaluating candidates' skills, motivations, and cultural fit during hiring processes, typically in later interview stages to enable deeper, conversational exploration beyond rigid scripting. This approach balances consistency—via a core set of open-ended questions—with adaptability, permitting interviewers to tailor follow-ups based on individual responses and fostering authentic dialogue that reveals candidates' experiences.^[36] Within primary care, semi-structured interviews are employed to gather patient feedback on healthcare experiences, enabling providers to identify service gaps and improve care delivery through targeted yet flexible questioning. For instance, in 2019, research demonstrated their feasibility in primary care settings, where they balance relational rapport with rigorous data collection to explore patient perspectives effectively.^[1] In user experience (UX) design, these interviews help designers empathize with users by probing needs, pain points, and behaviors, often using an interview guide with open-ended prompts like "Tell me about a time when..." to inform product development iteratively.^[37] A practical example of their integration in talent assessment comes from Clevry, a skills-based hiring platform, which in 2024 advocated for semi-structured interviews to enhance recruitment by combining open-ended questions with competency-focused follow-ups, thereby reducing bias and improving candidate evaluation accuracy. Post-2020, adaptations to virtual formats have become prevalent in remote hiring, with semi-structured interviews conducted via video platforms to accommodate distributed teams while preserving conversational depth and flexibility.^[38]

Data Analysis Approaches

Transcription and Initial Processing

Following the execution of a semi-structured interview, where audio or video recordings are typically captured to ensure comprehensive data collection, the transcription process begins to convert raw recordings into textual form for further handling.^[33] Verbatim transcription captures every word, including filler sounds like "um" or "ah," repetitions, and grammatical errors, preserving the exact phrasing to maintain the participant's original intent and nuances in qualitative analysis.^[39] In contrast, intelligent verbatim (or clean) transcription removes fillers, corrects minor grammatical issues, and streamlines false starts for readability while retaining core meaning, which is often preferred when the focus is on content rather than delivery style.^[39] Tools such as Otter.ai facilitate this by providing automated AI-assisted transcription, allowing researchers to upload recordings for quick initial drafts that can then be edited manually.^[40] Initial organization of the transcript involves several key steps to prepare the data ethically and practically. Anonymization is essential, achieved by replacing personal identifiers—such as names, locations, or specific affiliations—with pseudonyms or generic terms to protect participant confidentiality.^[41] Non-verbal cues, including pauses, laughter, gestures, or tone shifts observed during the interview, should be noted in brackets (e.g., [laughs] or [pauses for 5 seconds]) to contextualize verbal responses without altering the spoken content.^[33] Additionally, timestamping key segments links the text back to the original recording, enabling efficient retrieval of specific moments for verification or deeper review.^[39] Quality checks form a critical part of initial processing to ensure the transcript's reliability. Researchers must listen to portions of the recording while reading the transcript to verify accuracy, correcting any errors from automated tools or human transcriptionists, which helps preserve the interview's contextual integrity.^[40] This step often includes cross-checking for completeness, such as confirming that probes or follow-up questions from the semi-structured guide are accurately represented.^[42]

Coding and Thematic Analysis

Coding and thematic analysis represent key interpretive methods applied to data from semi-structured interviews, enabling researchers to systematically identify patterns and derive meaning from participants' narratives. In the coding process, open coding serves as the initial step, where researchers break down the transcribed data into discrete concepts or categories by assigning provisional labels to segments of text, allowing emergent themes to surface without preconceived notions. This approach, foundational to grounded theory, facilitates a detailed examination of the data's richness, as seen in semi-structured interviews where flexible responses yield nuanced insights. Strauss and Corbin outline open coding as involving the fragmentation of data into smaller units for close analysis, emphasizing constant comparison to refine categories iteratively. Following open coding, axial coding integrates these categories by exploring relationships among them, such as causal conditions, contexts, and consequences, to build more coherent explanatory frameworks. This phase employs a coding paradigm that links core phenomena with surrounding elements, enhancing the depth of understanding in qualitative datasets from interviews. Strauss and Corbin describe axial coding as a systematic recombination of open codes around a central axis, which helps in specifying the properties and dimensions of categories while maintaining theoretical sensitivity.^[43] Selective coding then consolidates the analysis by selecting a central category and systematically relating other categories to it, culminating in a grounded theory that explains the phenomenon under study. This final integration step ensures the theory is densely woven and accounts for variations in the data, as applied in studies using semi-structured interview transcripts.^[44] Thematic analysis complements coding by focusing on identifying, analyzing, and reporting patterns (themes) within the data, offering a flexible method suitable for semi-structured interviews across various epistemological positions. Braun and Clarke's widely adopted six-phase model begins with familiarization, where researchers immerse themselves in the data through repeated reading and note-taking to gain an initial sense of the content. The second phase involves generating initial codes systematically across the entire dataset, labeling interesting features relevant to the research question. In the third phase, themes are searched for by collating codes into potential broader patterns, often using visual aids like mind maps. The fourth phase reviews these themes for coherence and fit with the coded extracts and overall data, refining or discarding as needed. Defining and naming themes in the fifth phase sharpens their essence and boundaries, while the sixth phase produces a scholarly report of the analysis with compelling examples from the data. This model promotes reflexivity and rigor, ensuring themes capture the dataset's complexities. Software tools enhance the efficiency of coding and thematic analysis by facilitating code management, visualization, and mixed-methods integration when semi-structured interview data includes quantitative elements. NVivo supports iterative coding through features like automated text searches, query tools for exploring code co-occurrences, and visualization matrices to map relationships, making it particularly useful for large interview datasets. ATLAS.ti similarly aids in organizing codes hierarchically, linking multimedia interview files, and generating networks to illustrate thematic connections, thereby streamlining the transition from open to axial coding stages. These tools, while not replacing researcher judgment, reduce manual effort and enable reproducible analysis workflows in qualitative research.^[45]^[46] Recent developments as of 2025 include the integration of artificial intelligence, particularly large language models (LLMs) like ChatGPT, to assist in thematic analysis of semi-structured interview data. These AI tools can generate initial codes, identify patterns, and suggest themes from transcripts, accelerating the process; however, they require human oversight to maintain interpretive validity and address potential biases.^[47]

Ethical and Cultural Aspects

Ethical Guidelines

Conducting semi-structured interviews requires adherence to core ethical principles to protect participants and ensure research integrity. Informed consent is fundamental, involving a clear explanation of the study's purpose, procedures, duration, potential risks and benefits, and how data will be used, allowing participants to voluntarily agree or decline without coercion.^[48] Confidentiality must be maintained by anonymizing data, using pseudonyms, and restricting access to protect participants' identities and sensitive information from unauthorized disclosure.^[48] Participants retain the right to withdraw at any time without repercussions, which researchers should emphasize during recruitment and throughout the process to respect autonomy.^[48] For research involving human subjects, obtaining approval from an Institutional Review Board (IRB) or equivalent ethics committee is typically required to evaluate potential harms and ensure compliance with ethical standards.^[49] Researchers must disclose the full purpose of the interview upfront and provide ongoing opportunities for clarification, fostering trust and transparency in the interaction.^[48] To manage power imbalances inherent in interviewer-interviewee dynamics, such as those arising from professional authority or cultural differences, interviewers should adopt a reflexive approach, clearly define their role, and create an equitable environment that minimizes undue influence.^[48] Data storage practices are critical for security; recordings and transcripts should be encrypted, stored in password-protected systems, and identifiers removed to prevent breaches.^[48] Legal compliance is essential, particularly for sensitive topics. In the European Union, interviews handling personal data must align with the General Data Protection Regulation (GDPR), which mandates lawful bases for processing (e.g., explicit consent), data minimization, and rights to access or erasure.^[50] In the United States, for health-related interviews involving protected health information, adherence to the Health Insurance Portability and Accountability Act (HIPAA) Privacy Rule is required, permitting disclosures for research only under specific conditions like IRB approval or waivers.^[51]

Cultural Considerations

Conducting semi-structured interviews across cultures requires intercultural competence to adapt questioning strategies to local norms, ensuring that probes and follow-ups respect varying communication styles. In collectivist societies, such as those in East Asia, participants may prefer indirect responses to maintain harmony, necessitating the use of open-ended vignettes or contextual prompts rather than direct confrontation to elicit authentic insights without causing discomfort.^[52] Pilot testing interview guides in the target cultural setting can further refine these adaptations, as demonstrated in studies with Hong Kong youth where initial questions were rephrased to align with platform-specific social media norms.^[52] To avoid cultural bias, interviewers must receive training on established frameworks like Hofstede's cultural dimensions, which highlight differences in power distance, individualism versus collectivism, and uncertainty avoidance that can influence participant openness and response patterns.^[53] For instance, high power distance cultures may lead to deferential answers from interviewees toward perceived authority figures, requiring interviewers to build rapport through humility and equality to mitigate hierarchical distortions.^[52] When language barriers exist, employing culturally sensitive translators who understand idiomatic expressions and nonverbal cues is essential, as literal translations can alter meanings and introduce unintended biases.^[54] Cross-cultural studies often encounter challenges like misinterpreting silence, which in many Asian contexts signifies thoughtful reflection rather than disengagement or disagreement, potentially leading researchers from low-context cultures to prematurely rephrase questions and disrupt the flow.^[54] In collectivist environments, such as in Cameroon, interviews may evolve into group discussions with uninvited contributors offering collaborative insights, contrasting with individualistic settings like the United States where responses remain solitary; recognizing these dynamics prevents data loss or misrepresentation.^[55] These considerations underscore the need for reflexive practices in global applications of semi-structured interviews to foster trusting, culturally attuned encounters.^[55]
