These bootstrap findings give us information on how saturation may be reached at different stopping points as new themes are discovered in new interviews and when the interviews are ordered randomly in different replications of the sample of interviews. Their definition was specifically intended for the practice of building and testing theoretical models using qualitative data and refers to the point at which the theoretical model being developed stabilizes. Across four datasets, approximately 80% to 92% of all concepts identified within the dataset were noted within the first 10 interviews. Thematic Analysis - A Guide with Examples. Take the number of new themes in the latest run (four) and divide by the number of themes in the base set (37). The interview was a follow-up qualitative inquiry into womens responses on a quantitative survey. The method we propose facilitates qualitative researchers choice among levels of assessment criteria along with a common description of those criteria that will allow readers to interpret conclusions regarding saturation with more or less confidence, depending on the strictness of the criteria used. Empirical research to address this issue began appearing in the literature in the early 2000s. Say were researching perceptions of climate change among conservative voters aged 50 and up, and we have collected data through a series of interviews. [26], Fugard & Potts [21], Galvin [20]) ignores the fact that most qualitative research employs non-probabilistic, purposive sampling suited to the nature and objectives of qualitative inquiry [28]. This study included 60 interviews with women at higher risk of HIV acquisition30 participants in Kenya and 30 in South Africa [31]. Yes This study included 40 individual interviews with African American men in the Southeast US about their health seeking behaviors [29]. For example, a researcher may use thematic analysis to analyze a survey data set in order to identify themes in the responses. How do you identify a theme in quantitative research? The interview guide contained 13 main questions, each with scripted sub-questions. . In this broader sense, saturation is often described as the point in data collection and analysis when new incoming data produces little or no new information to address the research question [4, 9, 1113]. Validation, Taken together, the concepts of base size, run length, and new information threshold allow researchers to choose how stringently they wish to apply the saturation conceptand the level of confidence they might have that data saturation was attained for a given sample (Fig 2). To provide the foundation for this approach, we define saturation and then review the work to date on estimating saturation and sample sizes for in-depth interviews. Thematic analysis can be used to analyze quantitative data sets in order to identify patterns and themes. The lower the new information threshold, the less likely an important number of themes may remain undiscovered in later interviews if data collection stops when the threshold is reached. Research Methods | Definitions, Types, Examples - Scribbr Finally, well write up our analysis of the data. Thematic analysis is a process of analyzing qualitative data to identify patterns (themes) within the data. And lastly, these descriptive statistics help. [9] conducted a stepwise inductive thematic analysis of 60 in-depth interviews among female sex workers in West Africa and discovered that 70% of all 114 identified themes turned up in the first six interviews, and 92% were identified within the first 12 interviews. PDF Answers to frequently asked questions about thematic analysis Theres the distinction between inductive and deductive approaches: Ask yourself: Does my theoretical framework give me a strong idea of what kind of themes I expect to find in the data (deductive), or am I planning to develop my own framework based on what I find (inductive)? 61). In quantitative research, you'll most likely use some form of statistical analysis. There are various approaches to conducting thematic analysis, but the most common form follows a six-step process: familiarization, coding, generating themes, reviewing themes, defining and naming themes, and writing up. For inductive thematic analyses this is a subjective decision that depends on the degree of coding granularity necessary for a particular analytic objective, and how the research team wants to discuss saturation when reporting study findings. What a quantitative researcher accepts, for example, as a large enough effect size or a small enough p-value is a subjective determination and based on convention in a particular field of study. Using the total number of themes in the dataset retrospectively, the number of themes evident across 67 interviews corresponded with a median degree of saturation of 78% to 82%. What can we change to make our themes work better? Given how different approaches arein terms of units of analysis and strictness of saturation thresholdsit is difficult to understand how much confidence to have in a conclusion about whether saturation was reached or not. Calculation is simple. This method can emphasize both organization and rich description of the data set and theoretically informed interpretation of meaning. Using the principle of saturation as a foundation, we describe and validate a simple-to-apply method for assessing and reporting on saturation in the context of inductive thematic analyses. It is a method for identifying, analyzing, organizing, describing, and reporting themes found within a data set (Braun & Clarke, 2006). Note that in our analyses, successive runs overlap: each set of interviews shifts to the right or forward in time by one event. Funding: The authors received no specific funding for this work. (which includes categorical and numerical data) using various statistical techniques. If analyzing data in real time, the results of this initial assessment can then determine whether or not more interviews are needed. There's no one way to do a thematic analysis. The researcher could look for relationships between the responses and other variables, such as age, gender, or education level. Those three questions generated 55 codes. Since we had available the total number of codes identified in each dataset, we carried out one additional calculation as a way to provide another metric to understand how the median number of interviews to reach a new information threshold related to retrospectively-assessed degrees of saturation with the entire dataset.

[The data used for each step are included in Fig 3, along with indication of the base, runs, and saturation points. The results for Dataset 2 were nearly identical to Dataset 1 (Table 3). In this example, were using a run length of two, so include data for the next two interviews after the base seti.e., interviews 5 and 6. All three studies were reviewed and approved by the FHI 360 Protection of Human Subjects Committee; the study which produced Dataset 3 was also reviewed and approved by local IRBs in Kenya and South Africa. At a run length of two interviews, the median number of interviews required before a drop in new information was observed was six. In our example, we decided that the code uncertainty made sense as a theme, with some other codes incorporated into it. Saturation will inevitably occur in a retrospectively-assessed, fully-analyzed, fixed-size dataset. [16] conducted a pioneer methodological study using data collected on environmental risks. https://doi.org/10.1371/journal.pone.0232076.t005. The inductive thematic analysis included 11 of the 13 questions and generated 93 unique codes. They further argue that the stopping point for an inductive study is typically determined by the judgement and experience of researchers. When to use thematic analysis. This is done by randomly resampling from the sample with replacement (i.e., an item may be selected more than once in a resample) many times in a way that mimics the original sampling scheme. That is where we rely on the empirical research that shows the rate at which new information emerges decreases over time and that the most common and salient themes are generated early, assuming that we keep the interview questions, sample characteristics, and other study parameters relatively consistent. Hagaman and Wutich (2017) and Francis et al. . Validation, We describe how this method circumvents many of the limitations associated with other ways of conceptualizing, assessing and reporting on saturation within an in-depth interview context. Yes We then identified the number of transcripts needed to meet a new information threshold of 5% or 0%. Interested in ChatGPT For 1-on-1 Interviews? Can we conduct thematic analysis of secondary data? Can comparison be made using thematic analysis in Qualitative Second, thematic analysis can be used to identify patterns in the data that could not be identified through other methods. Some types of research questions you might use theme-oriented analysis to answer: Thematic analysis remains a goods approach to research where you're trying to find out something about people's views, considerations, skills, adventures or values from a set to qualitative data - for example, interview transcripts, social media profiles, or survey responses. Quantitative content analysis is a research method in which features of textual, visual, or aural material are systematically categorized and recorded so that they can be analyzed. This can then be compared across base sizes, run lengths, and new information thresholds. Assign preliminary codes to your data in order to describe the content.

This can be particularly useful when the data is complex or when the researcher is looking to uncover relationships between the data and other variables. Interested in ChatGPT For Academic Papers? Similarly, the method allows for different optionsand greater clarity and transparencyin describing and reporting on saturation. There are several benefits to using thematic analysis in quantitative research. TimesMojo is a social question-and-answer website where you can get all the answers to your questions. Here, we return to the data set and compare our themes against it. The second question is to a degree related to the first question and pertains to possible order effects. Most of the time, youll combine several codes into a single theme. Though it is possible an important theme will emerge later in the process/dataset, the empirical studies referenced above demonstrate that the most prevalent, high-level, themes are identified very early on in data collection, within about six interviews. Attempting rigour and replicability in thematic analysis of qualitative Check out the dedicated article the Speak Ai team put together on Can Thematic Analysis Be Used In Quantitative Research? How both quantitative and qualitative data is collected and Analysed? It's a site that collects all the most frequently asked questions and answers, so you don't have to spend hours on searching anywhere else. Research Methods As all researchers know, reality often presents surprises. We also know from previous studies [9, 16, 29] that most novel information in a qualitative dataset is generated early in the process, and generally follows an asymptotic curve, with a relatively sharp decline in new information occurring after just a small number of data collection/analysis events. What Is a Research Design | Types, Guide & Examples - Scribbr through semi-structured interviews or open-ended survey questions) and explaining how we conducted the thematic analysis itself. After reviewing those interviews, lets say we identified four new themes in interview 5 and three new themes in interview 6. The number of themes evident across 68 interviews corresponded with a median degree of saturation of 79% to 82%. Can You Do Thematic Analysis In Quantitative Research? The two main types of quantitative data are discrete data and continuous data. This can help the researcher to better understand the data and draw more meaningful conclusions. Likewise, while an odds ratio of 1.2 may be statistically significant, whether or not its meaningful in a real-world sense is entirely open to interpretation. Thematic analysis is a good approach to research where you're trying to find out something about people's views, opinions, knowledge, experiences or values from a set of qualitative data - for example, interview transcripts, social media profiles, or survey responses. This type of analysis can be particularly useful when the data is complex or when the researcher is looking to uncover relationships between the data and other variables. Theres also the distinction between a semantic and a latent approach: Ask yourself: Am I interested in peoples stated opinions (semantic) or in what their statements reveal about their assumptions and social context (latent)? Interested in Can Thematic Analysis Be Used In Quantitative Research?? No, Is the Subject Area "Metaanalysis" applicable to this article? In your research, you might only use descriptive statistics, or you might use a mix of both, depending on what you're trying to figure out. Many qualitative data analyses, however, do not use the specific grounded theory method, but rather a more general inductive thematic analysis. Qualitative research seeks to understand why people react and how they feel about a specific situation. How to transcribe a Microsoft Teams Meeting, What Is A Acoustic Model In Speech Recognition, What Is A Normal Speech Recognition Threshold. This reflects similar developments in primary research in mixing methods to examine the relationship between theory and empirical data which . We start by looking at the first four interviews conducted and summing the number of unique themes identified within this group. Many policy researchers are predisposed to use either quantitative or qualitative research methods regardless of the research questions at hand, leading to varying degrees of gaps in . Some types of research questions you might use thematic analysis to answer: To answer any of these questions, you would collect data from a group of relevant participants and then analyze it. Pay close attention to the data to ensure that youre not picking up on things that are not there or obscuring things that are. The interviews following Interview 12, though yielding four additional themes, remained at or below the 5% new information threshold. Mixed methods dissertations combine qualitative and quantitative approaches to research. For example, we might decide upon looking through the data that changing terminology fits better under the uncertainty theme than under distrust of experts, since the data labelled with this code involves confusion, not necessarily distrust. Based on the bootstrapping analyses we can draw several conclusions. Central to content analysis is the process of coding, which . Dataset 3. It was developed with applied inductive thematic analyses in mindthose for which the research is designed to answer a relatively narrow question about a specific real-world issue or problemand the datasets used in the bootstrapping analyses were generated and analyzed within this framework. Basing assessments of saturation on probabilistic assumptions (e.g., Lowe et al. Descriptives describe your sample, whereas inferentials make predictions about what youll find in the population. Saldaa, J. How to Analyze Qualitative Data from UX Research: Thematic Analysis Thematic coding, also called thematic analysis, is a type of qualitative data analysis that finds themes in text by analyzing the meaning of words and sentence structure. If you continue to use this site we will assume that you are happy with it. Inductive probing was employed throughout all interviews. Quantitative research focuses on numeric data and therefore the aim to achieve objectivity is far easier than in the qualitative research. Caulfield, J. Since the last two interviews did not add substantially to the body of information collected, we would say that saturation was reached at interview 6 (each of the next two interviews were completed to see how much new information would be generated and whether this would fall below the set threshold). It can be used to find patterns and averages, make predictions, test causal relationships, and generalize results to wider populations. Another potential limitation of this method relates to codebook structure. In this paper we present a way of assessing thematic saturation in inductive analysis of qualitative interviews. Estimates are based on (specified) assumptions, and expectations regarding various elements in a particular study. [9], Hennink et al. We can also draw other lessons to inform application of this process: There are, of course, still limitations to this approach. At this point the proportion of new information added by the last run is below the 5% threshold we established, so we stop here after the 8th interview and have a good sense that the amount of new information is diminishing to a level where we could say saturation has been reached based on our subjective metric of 5%. Even in cases where random sampling is employed, the open-ended nature of qualitative inquiry doesnt lend itself well to probability theory or statistical inference to a larger population because response categories are not structured, so are not mutually exclusive. These codes allow us to gain a a condensed overview of the main points and common meanings that recur throughout the data. Data from all three studies were digitally recorded and transcribed using a transcription protocol [32]; transcripts were translated to English for Dataset 3. The metrics are flexible. Now that you have a final list of themes, its time to name and define each of them. 17). The same can be said for . Roles The fact that IPA is better thought of as a methodology (a theoretically informed framework for how you do research) rather than a method (a technique for collecting/analysing data), whereas TA is just a method. Thematic analysis is a popular six-phased approach to analysing qualitative data; however, very few studies adopting this approach have explicitly demonstrated step-by-step and explained the whole . For each resample, we calculated the proportion of new themes found in run lengths of two or three new events relative to a base size of four, five or six interviews. That said, a researcher could, with this approach, run and report on saturation analyses of two or more codebooks that contain differing levels of coding granularity. But, to further check this, we use a bootstrapping technique on three actual datasets to corroborate findings from these earlier studies and to assess the distributional properties of our proposed metrics. Check out the dedicated article the Speak Ai team put together on What Is A Normal Speech Recognition Threshold to learn more. Quantitative data analysis. Because the data is collected and analyzed in a statistically valid way, the results of quantitative analysis can be easily standardized and shared among researchers. The first is that the results are within the range of what we would have expected based on previous empirical studies. We know that if we use all of the data collection events as our base size, we can reach saturation by default as there are no more data to consider. This might involve transcribing audio, reading through the text and taking initial notes, and generally looking through the data to get familiar with it. Are codes in thematic analysis quantitative or qualitative? The process can be applied either prospectively during the data collection and analysis process or retrospectively, after data collection and analysis are complete. and How do we know if we have reached saturation? How to Do Thematic Analysis | Step-by-Step Guide & Examples. Thematic analysis helps you make your qualitative study more accurate. Can thematic analysis be used in literature review? PLoS ONE 15(5): Check out the dedicated article the Speak Ai team put together on ChatGPT For Academic Papers to learn more. Quantitative data is data that can be counted or measured in numerical values. We use cookies to ensure that we give you the best experience on our website. [23] for discussion on this as it relates to saturation). Generate accurate APA, MLA, and Chicago citations for free with Scribbr's Citation Generator. Understanding and Identifying 'Themes' in Qualitative Case Study Research Investigation, Results will aim to offer an account of current understandings of patient experiences and perspective regarding PICC, Hickman-type, and Port devices in the context of anti-cancer . In triangulation methods of research, thematic analysis (Braun & Clarke, 2006) could be used to analysed for open . Base size refers to how we circumscribe the body of information already identified in a dataset to subsequently use as a denominator (similar to Francis et al.s initial analysis sample).
