Abstract
Quantitative researchers traditionally use cognitive pretesting methods such as think-alouds to determine whether participants are interpreting close-ended survey items as intended. I applied this method to evaluate the score validity of quantitative survey instruments with a middle school and high school sample of students. Through these applications, the cognitive pretesting method also revealed to be a useful tool for cueing participants’ reflection on their experiences related to the phenomenon of interest. Qualitative researchers traditionally use more open-ended interviews guided by general “how” and “why” questions, which might not serve as sufficient prompts to elicit participants’ reflection on their experiences, especially younger participants. To date, there are no illustrative examples focused on how having participants think-aloud as they complete a quantitative survey can inform qualitative-focused or mixed research questions. Therefore, the purpose of this article was to illustrate how the cognitive pretesting method, where participants think-aloud as they complete a survey, can be used as an additional technique to gain insight into their experiences of a phenomenon. The phenomenon in this illustration was defined as the participants’ experiences with the science content that they were learning in school. Limitations and methodological challenges and recommendations for overcoming these barriers are also discussed.
Qualitative researchers traditionally use more open-ended interviews guided by general “how” and “why” questions to gain insight into participants’ experiences. These questions might not serve as sufficient prompts to elicit participants’ reflection on their experiences, especially younger participants. To date, there are no illustrative examples focused on how having participants think-aloud as they complete a quantitative survey can be used as a tool for gaining insight into participants’ experiences beyond evaluating their experiences with the survey itself. The illustration in this article advances the development of qualitative research methods by providing an adaptation of a cognitive pretesting protocol as an alternative method for gaining insight into participants’ experiences using the familiar context of responding to a survey.
Cognitive pretesting, as applied in survey research, is used as a method for investigating whether participants interpret close-ended items as intended to inform revisions in item wording prior to larger administration of a survey or test (Tourangeau, Rips, & Rasinski, 2000; Willis, 2005). Although cognitive pretesting and cognitive interviewing are not new methods, they continue to evolve. Karabenick et al. (2007) contributed to the literature through outlining a specific procedure for conducting cognitive interviewing and analyzing data produced by think-alouds to inform the validity of inferences drawn from quantitative surveys. This procedure has since been applied in research evaluating the score validity of previously established and widely adopted instruments (e.g., Koskey, Karabenick, Woolley, Bonney, & Ammon, 2010). Briefly, this procedure involves having participants think-aloud as they respond to a survey. Participants are asked to share, in their own words, what they believe the survey item is asking, what they would choose as their answer or rating, and why they chose that response. The researcher rates participants’ responses in terms of how closely their interpretations of the survey item aligned with what the survey developer intended to assess.
In this article, I focus on how researchers can move beyond using the cognitive pretesting method for informing survey item revisions. I invite you to join me in the journey that I share of my realization of the wider application of this method. In this article, cognitive interviewing as it relates to cognitive pretesting and its traditional uses are briefly overviewed. Within this description, I review the cognitive pretesting think-aloud procedure outlined by Karabenick et al. (2007). Next, I describe how a more structured prescribed procedure also can be used to cue participants’ reflection on their experiences and, then, I provide an illustration using data from a previous study. Finally, a reflection is provided on the limitations and methodological barriers that might be faced when employing this method.
Epistemological Frame
Prior to addressing the purposes of this article, it is necessary to discuss the lens from which I write. My formal training is in psychometrics or measurement and statistics. Thus, my initial tendency is to have a more postpositivist worldview described as “a replacement [of positivism] that is still bound to the quantitatively oriented vision of science” (Teddlie & Tashakkori, 2009, p. 69). As a result of this worldview, my research in the past was strictly quantitative. In fact, it is admittedly unusual for me to write in first person and to reflect on my subjectivity, as my formal training is to avoid doing so.
This being stated, I never aligned with being a purist and agreed with Reichardt and Rallis (1994) that “any given set of data can be explained by many theories” (p. 88). As I focused my research on constructing attitudinal measures and evaluating the psychometric properties of established measures, I found a number of patterns observed in quantitative data that could not be explained by numbers alone. Over the past few years, I aligned more with the pragmatist view, recognizing that both postpositivism and constructivism are valuable worldviews, and that the method adopted is driven by the research problem and question (Feilzer, 2010; Johnson & Onwuegbuzie, 2004; Teddlie & Tashakkori, 2009). Over the past 7 years, my colleagues and I have conducted a handful of studies employing cognitive pretesting methods to evaluate the quality of attitudinal measures and their associated rating scales to complement and to inform the data yielded from quantitative techniques for assessing score reliability and score validity. The call for this special issue was timely in that a few months prior to the call, I completed coding data elicited by cognitive think-alouds and experienced this realization of the greater potential use of this method in qualitative research.
Overview of Cognitive Interviewing in Pretesting Surveys
Cognitive interviewing is defined as an “intensive, extended, think-aloud, or laboratory pretest interview” (Willis, 2004, pp. 23–24). It is one of many cognitive pretesting methods used to evaluate whether participants interpret close-ended items on a survey as intended by the survey designer to provide validity evidence or to inform item revisions. Close-ended refers to survey items rated on a predefined or fixed scale such as a Likert-type scale ranging from
Cognitive interviewing has a long history of being applied to improve the survey design such as to inform the presentation of items and rating scale adopted (for a review, see Sirken et al., 1999; Sudman et al., 1996; Tourangeau et al., 2000). Nevertheless, as a method, it is typically “not carried out primarily for the purpose of developing questionnaire design, but rather, to evaluate targeted survey questions, with the goal of modifying these questions when indicated” (Willis, 2004, p. 23). These modifications are indicated when misalignment emerges between participants’ interpretations and a researcher’s intention. Participants’ qualitative responses then are used to guide revisions to individual items. One of the challenges identified in using cognitive interviewing for eliciting participants’ thought processes is “to gain information about the associated thought states without altering the structure of the course of the naturally occurring thought sequences” (Ericsson & Simon, 1998, pp. 180–181). The goal is to elicit verbalizations from participants who represent the thought processes that they would have if completing the task under normal circumstances.
Verbal probing or questioning is one method used in cognitive interviewing to elicit these processes. A think-aloud task is another method used in cognitive interviewing requiring participants to verbalize their thought process, which is the focus of this article. Traditionally, think-aloud tasks require limited interchange between the interviewer and participant (Ericsson & Simon, 1980, 1993). In a think-aloud task, participants are asked to verbalize their thought processes either during (concurrent verbalization) or immediately after (retrospective verbalization) completing a task. The interviewer simply instructs a participant to “say what you are thinking” as he or she completes the task or to “say what you were thinking” after completing the task. Some researchers provide a video of the participant completing the task to assist them in recalling what he or she was thinking if using retrospective verbalization.
Minimal reactivity effects have been found when participants think aloud while completing a survey (Ericsson & Simon, 1980; Fowler, 1995; Low, 1999; Willis, 2004). Specifically, verbalization during a self-administered survey requires what Ericsson and Simon (1980) classified as Level-2 verbalizations, wherein participants transform their thoughts into words to verbalize but without changing the sequence of those thoughts. In other words, the verbalizations expressed during the think-aloud are close to representing the thoughts as they naturally occur. Level-2 verbalizations differ from Level-1 verbalizations in that Level 1 does not require the thoughts to be transformed before they are verbalized. Boren and Ramey (2000) provide an example of participants “who verbalize sequences of numbers while solving a math problem” as producing Level-1 verbalizations “because numbers can be verbalized in the same form as they were originally encoded” (p. 262). In addition to Level-2 verbalizations, the task requires participants to process information in their consciousness as opposed to using automatic or nonconscious processing. Finally, the task involves verbal processing that takes at least a few seconds but not more than 10 s, further indicating that information is processed in the consciousness but not to the point of automatic processing (Ericsson & Simon, 1980).
Measures to minimize reactivity during a think-aloud task are recommended such as the use of minimal verbal probing to allow participants to “maintain undisrupted focus on completion of the presented task” (Ericsson & Simon, 1998, p. 181). If too much verbal probing is employed, then what Ericsson and Simon referred to as Level-3 verbalization might occur, requiring participants to retrieve information that they are not initially attending to prior to the verbal prompt. This retrieval could result in interference and an inaccurate representation of the thought processes that they would experience when completing the task under authentic conditions. Such retrieval is problematic if using cognitive pretesting for the purpose of determining what participants are thinking as they complete a survey to inform whether they interpret and interact with the items as intended. The reason that it is problematic is that the researcher does not want to prompt participants to reflect more than they normally would when responding to a survey item under normal conditions (e.g., sitting completing the survey on their own).
Imagine you are completing a survey asking you to rate how you feel about a series of statements. You most likely will read the first survey item, consider what it is asking, retrieve the needed memory, and then respond using the scale provided and move to the next item. You probably do not spend more than 30 seconds responding to each item. Too much verbal probing as to why you chose the answer or rating that you selected could lead you to retrieve information about your experiences that you normally would not think about if taking the survey without thinking aloud. This being stated, Hughes (2004) found differences in the usefulness of data produced when comparing different cognitive pretesting methods employing varying levels of verbal probing. Specifically, cognitive interviewing and respondent debriefing were more likely to identify problems with the survey wording or design compared to behavior coding of the interaction. Cognitive interviewing and respondent debriefing both provided for probing of participants’ thoughts through preestablished probes or follow-up questions, respectively. I propose that using verbal probing to access Level-3 verbalizations is not problematic when the purpose is to gain deep insight into participants’ experiences, attitudes, and feelings. Thinking aloud while completing a survey can purposefully be used to cue the retrieval and expression of participants’ experiences related to a phenomenon of interest.
Karabenick et al.’s Cognitive Pretesting Method
Karabenick et al. (2007) proposed a systematic procedure for implementing a cognitive think-aloud task and analyzing the verbalizations produced. Multiple methods for conducting cognitive interviews and analyzing the verbal data produced exist (DeMaio & Landreth, 2004; Hughes, 2004). Several researchers (e.g., Hastie, 1987; Strack & Martin, 1987; Sudman et al., 1996; Tourangeau, 1984) have proposed models applying an information-processing model to participants’ thought processes as they complete a survey. Similarly, we applied six information-processing steps to this method with the goal of accessing participants’ short-term memory databases. The short-term memory being accessed was the immediate interpretation of an item meaning. The long-term memory being accessed was the experiences on which participants reflect while explaining their answer choice to a survey item. The six information-processing steps are outlined in detail in Karabenick et al. (2007); a brief overview is provided here. Steps 1 and 2 entail reading and interpreting the survey item and storing that interpretation in working memory. Step 3 involves accessing memories, experiences, attitudes, and associations relevant to the survey item. Steps 4 through 6 involve reading and interpreting the rating scale to select a response option, using the memories elicited to inform which number or label best aligns with the experiences accessed.
Participants are guided through this six-step process during a one-to-one interview where they are asked to think-aloud as they complete the survey with an interviewer who follows a structured script. Prior to beginning the task, participants engage in a practice task with one or more items until they feel comfortable thinking aloud. Rather than simply asking participants to “think aloud,” the script includes three core prompts that provide guidance and structure on how to verbalize their thoughts. The three core prompts comprise: (a) what is this question trying to find out from you, (b) which number do you choose as your answer or which number represents how you feel, and (c) explain why you chose that answer. Limited verbal probing is used unless participants have difficulty verbalizing their thoughts. In these cases, an interviewer selects from a number of predefined probes such as “can you give me an example?” or “can you share a little more about why you chose that number?” This script is repeated for each item. After participants engage with 1–3 items, limited prompting is needed to remind them to think-aloud. In fact, participants often go through the steps for each item without needing these guiding questions from the interviewer due to the repetitious nature of what is requested as they think-aloud for each item.
The verbalizations then are transcribed for coding ideally by multiple raters using three criteria, defined by Karabenick et al. (2007) as:
Further, raters make a more holistic judgment of the overall alignment of a participant’s verbalization by assigning an overall
The criteria for what constitutes a congruent interpretation, elaboration, and answer choice are defined using coding sheets created by the original survey developer or another expert on the construct or phenomenon under study. A coding sheet is created for each item and used to support raters as they judge how closely a participant’s interpretation aligns with what the survey developer designed the item to assess. An example coding sheet is provided in Appendix A. The detailed procedure for applying the codes is outlined by Karabenick et al. (2007). Further, an example application has been provided by Koskey et al. (2010) where the method was applied to evaluate the quality of a widely used and previously established measure of mastery goal structure (Patterns of Adaptive Learning Survey; Midgley et al., 2000).
After completing the coding independently, interrater reliability then is computed across the raters and disagreements in ratings assigned are resolved. The final ratings for the three criteria for each item across participants then are aggregated. These findings are used to indicate which items have a low congruency rating for each criteria and an overall low congruent validity rating to flag items needing revision. Specific revisions are guided by the qualitative verbalizations collected. Also, during the coding process, raters take notes as to any observations in misinterpretations, which are, in turn, used to inform revisions needed. For example, a word or term that is commonly misinterpreted or misread might be highlighted in the raters’ notes. Participants’ verbalizations with high cognitive validity ratings can be referred to for ideas on how to reword the item or to revise it to more simplistic terms.
Repurposing the Cognitive-Pretesting Method
Through my experience employing this method and coding the verbalizations across a number of studies, I found having participants think-aloud as they complete a survey could elicit rich data on their experiences with the construct being measured, beyond their interpretation of the item meaning. The traditional purpose(s) of each component of the cognitive-pretesting method and the proposed alternative purpose(s) are outlined in Table 1.
Traditional and Newly Proposed Purposes of Cognitive Pretesting Method.
aPrompts can be adapted depending on the topic and rating scale (numbers, labels, numbers and labels) used.
As outlined in Table 1, the procedure for conducting the think-aloud remains, with each component reframed for the purpose of gaining insight on participants’ experiences, attitudes, or feelings related to the phenomenon or topic of interest. Item interpretation serves as an initial cue then to instigate the retrieval of memories, experiences, and associations related to the phenomenon. Selecting an answer choice indicates the degree or direction of the experience, attitude, or feeling. It is important to note here that it is not being suggested that participants’ experiences can necessarily be quantified or be represented by a single rating or label. On the contrary, the choices provided may be numeric, qualitative labels, or even illustrations if interviewing a younger sample. The purpose of the answer choice is to gain general insight on the direction of their experiences or feelings (e.g., positive or negative, less to more, and weak or strong) to cue further elaboration and to provide an opportunity for a participant to share that the statement does not represent his or her experiences.
Asking a participant to elaborate on why he or she chose a particular answer or rating cues Level-3 verbalizations described earlier (Ericsson & Simon, 1998). It is at the point of elaboration wherein I find that the traditional and alternative purposes diverge the most. Traditionally, the purpose of elaboration is to assess the degree of validity of the verbalizations with intended item meaning and congruency with the answer choice selected (e.g., if a participant chose “strongly disagree,” his or her elaborations support that he or she strongly disagrees). Limited additional probing is used in the traditional method so as not to alter what they would be thinking about if they took the survey in an authentic context without thinking aloud. Also, at this point in the think-aloud, the interviewer typically has sufficient information to make a judgment as to whether a participant interpreted the item as intended and can move forward to the next item. Conversely, the proposed alternative purpose is to instigate deeper reflection in an effort to elicit deeper-level memories or experiences. To achieve this goal, additional probing such as requesting to share further examples from the participant’s own life might be needed, which is a departure from the traditional method. In my experience, the prompt asking “why did you choose that as your answer?” cues participants to provide examples to support their ratings; however, further prompting might be needed to gain a deeper understanding of their rationale.
An interesting phenomenon related to the latter purpose of instigating deeper reflection occurred during a think-aloud interview that I conducted with a middle school science student. The interview was conducted to inform the development of a measure focused on assessing the engagement of students with content that they were learning in the classroom related to properties of matter. The student had completed a unit on properties of matter a week before. In the course of the interview, the student was presented with the item
For instance, another student elaborated that he or she does not notice examples of the properties of matter outside of class and gave an example when he or she plays in the snow: “Disagree because it’s really my brain’s relaxing time while I’m out there so I’m not really thinking ‘Oh look at all the solid, look at all the water.’ I’m saying, ‘I can build a snow man!’” This student’s response communicated that he does not have this experience of seeing things through the lens of properties of matter. Still, in the context of the think-aloud, he or she was able to describe accurately an experience in which he or she might have been able to see things in this way. The think-aloud provided the opportunity for this student to make such a connection. In comparison, the exchange below illustrates a student elaborating that he or she does have this experience outside of class when asked what rating he or she would choose when presented with the item
Agree. I find them without them coming to me. My brother challenges me to find different kinds of things.
Can you give me an example of what you mean when you say you “have a brother challenge you to find different things”? What does he do?
Like, once he challenged me to find a gas inside of a solid, so I went to the freezer and I got an ice cube that had a little bubble of air in it.
I do not propose that this method be used to replace more in-depth interviewing, but rather to assist participants in verbalizing what might otherwise be difficult experiences to retrieve without prompting. The process could complement a more open-ended in-depth interview that follows. Figure 1 outlines the overall phases of the process, not meant to be prescriptive, but rather offered as a framework for applying the repurposed alternative method for the purpose of gaining insight into participants’ experiences, attitudes, and feelings.
Outline for adapting the cognitive pretesting method.
Regarding the analysis phase, the coding scheme proposed by Karabenick et al. (2007) can be applied or adapted to gain surface-level insight as to whether a participant’s experience, attitudes, or feelings aligned with the statements, focusing mainly on the coherent elaboration ratings. However, it is recommended that a more in-depth analysis be conducted on the resultant verbalizations within each item and across the items. Verbalizations for a single item are not intended to represent a participant’s experience, attitude, or feeling. A holistic analysis of the verbalizations across the items is necessary to infer and to represent a participant’s experiences. Thus, it is essential to generate multiple and a realm of statements to present to participants. If too narrow of a realm of statements are presented to participants, then the experiences shared might be limited. If a researcher selects statements or questions that only represent his or her experiences, selection bias could occur with the items selected impacting the results. To minimize the degree of selection bias in the statements or questions presented to participants, researchers should use prior literature and theory to guide the selection.
Leech and Onwuegbuzie (2007) recommend applying multiple data analysis techniques such as content analysis, keywords-in-context analysis, and constant comparative analysis and then to triangulate the findings to inform the research question(s). The analysis approach depends on the research purpose(s) and research question(s) being addressed. For instance, if the research question relates to gaining insight on a particular group of participants’ perceptions about a phenomenon, then a thematic analysis might be applied, followed by constant comparative analysis through identifying the emergent phrases or
Example Illustration
To illustrate the insight that can be gained from employing this method, two cases are presented using data collected to examine the phenomenon of transformative experience. Briefly, transformative experience is a construct nested in Dewey’s (1938, 1934/1980) theory of aesthetics and described by Pugh (2011) as representing a student’s engagement with the content that they are learning, extending beyond the classroom. Pugh conceptualized transformative experience as consisting of three qualities: behavioral (motivated use for the content), cognitive (expansion of perception), and affective (experiential value). Motivated use is defined as the application of the content in one’s everyday life without being required to do so. Expansion of perception refers to seeing the world in a new way, through the lens of the content learned. The third quality, experiential value, relates to holding a value for the utility of the content in everyday experiences. Pugh and his colleagues (Girod & Wong, 2002; Pugh, 2004) previously attempted to gain insight into students’ transformative experiences through traditional interviewing techniques and open-ended questioning. They later sought to construct a measure guided by the theory and their findings from qualitative research studies to attempt to measure this holistic construct to assess the degree to which students engaged with content from inside to outside the classroom.
The two cases illustrated here were drawn from a study focused on evaluating the psychometric properties of adaptations of the previously established Transformative Experience Questionnaire (TEQ; Pugh, Kleshinski, Linnenbrink, & Fox, 2004). The TEQ is a 28-item instrument assessing students’ degree of engagement with content that they are learning in the classroom, with each item rated on a 4-point scale ranging from
In this study, qualitative think-aloud data from a subsample of students were quantitized and used to inform the quality of the items (if students interpreted the items and used the rating scale as intended) to provide validity evidence and to guide further item revisions. The students were asked on the student assent form if they were willing to participate in the think-aloud task. Of those who responded “yes,” 20 students were randomly selected to participate. The researchers verified on the day of the interview whether each student was still willing to participate. A total of 19 students participated.
Alternative sampling methods should be considered depending on the research purpose. For instance, if the purpose were to represent the realm of experiences, an alternative method would be to apply a sequential mixed methods research design by asking participants first to respond to the survey to identify participants with low scores, midrange scores, and high scores to represent the continuum of responses in the sample. It is also possible that sampling a small number of participants will not represent the realm of experiences. Indeed, Blair and Conrad (2011) found that when conducting cognitive pretesting for the purpose of informing score validity, the probability of detecting issues with a survey increased as the number of participants increased. Literature on determining sample sizes for interviewing provides further guidance on sampling (e.g., Creswell, 2007; Graves, 2002; Guest, Bunce, & Johnson, 2006).
I chose to present the responses of two students’ verbalizations across 3 of the 28 items for three major reasons. First, the richness of the data yielded from the verbalizations could not be observed from the think-aloud for a single item alone. The students’ degree of transformative experience had to be examined holistically across the multiple items intended to represent a transformative experience. Second, it was too cumbersome to present a full transcript for the entire think-aloud task for all 28-items that would more accurately represent the richness of the data. Instead, 3 items focusing on engagement with the content outside of school were selected for illustrative purposes here. Third, a case where a higher degree of transformative experience and a case where a lower degree of transformative experience were reported as evidenced by the answer choice ratings were selected. The purpose of selecting a case from both extremes was to demonstrate how this method might overcome the potential of statements to bias a participant’s responses. The second case also demonstrated that the task could provide the opportunity for a participant to disagree with the experiences in the statements as presented.
Table 2 presents the transcript for a ninth-grade, 15-year-old female exhibiting a high degree of transformative experience with the topic of human rights through agreeing or strongly agreeing to the statements. She self-reported her race as multicultural, her current grade in World History as an “A,” and her grade point average as 4.5 on a 5-point scale. Table 3 presents the transcript for a sixth-grade, 12-year-old male exhibiting a low degree of transformative experience with the topic of properties of matter through disagreeing to the statements. He self-reported his race as White and his current grade in Science as an “A.” This student did not report his grade point average. Both students were from a suburban school district in the Midwest in the United States. A researcher trained in cognitive pretesting conducted the interviews. The interviews took place in a study room in the school library and each were approximately 30 min in duration.

Methodological Considerations and Concluding Thoughts
Limitations exist when applying this method for the purposes of gaining insight on participants’ experiences, attitudes, or feelings. As with all research, techniques for minimizing limitations must be planned for when implementing this method. A few of these limitations and recommendations for how to address each are highlighted next.
First, as noted earlier, bias can occur in the selection process of the statements to present to participants. Researchers could select statements that represent their own experiences or perceptions. This limitation also exists when formulating open-ended interview questions. Techniques for minimizing this degree of bias are to have other experts or participants from the target sample review and corroborate the statements. Also, researchers should allow prior literature to guide the generation of statements. A related limitation is that an item presented earlier during the interview could prime the response to a later item, potentially presenting a testing and an instrumentation threat to internal validity (Campbell & Stanley, 1966).
Second, the statements selected might not represent the full realm of experiences or the experiences of participants interviewed, which is why I recommend complementing this task with additional open-ended interview questions after the task or in a different phase of the study. Some participants might need additional time to reflect on their thoughts. The transcripts presented in this article were purposefully selected as exemplars of participants able to verbalize their thoughts clearly as reflected in the clarity of the transcripts. The exemplars presented do not represent the realm of experiences across all of the students in this example. Some of the students were not able to verbalize their thoughts clearly or felt comfortable completing the think-aloud task. Of the 19 students who completed the task, 1 student requested to end the interview after 11 min because he or she felt uncomfortable thinking aloud. Other students lacked elaboration in their responses. As an example, this sixth-grade male adolescent had a pattern of difficulty in elaborating on his answer choice:
Okay, how about number three.
And what’s that trying to find out from you?
Like, if I like … I don’t know. I’m not good at this.
You’re doing just fine. Would you like to keep going or stop?
Um … like it’s asking if I like, I don’t know.
Okay, what is it about this one that is confusing?
Like, I don’t know what it’s really asking.
Okay, go ahead and read it one more time.
Yep. Good. And how would your rate that one?
Strongly disagree.
And why do you say that?
Because … I don’t know.
Similarly, the answer choices presented might be too limiting or not provide a representation of how a participant feels. Thus, the researcher needs to be prepared for participants to share alternative numbers or labels as their answer choices from those provided. For instance, when I applied the same method for investigating the score validity of a survey assessing attitudes toward statistics using a 10-point scale, a participant responded that he or she wanted to rate an item 100 to represent how strongly he or she agreed with a statement.
Additionally, the verbalizations could only yield a surface-level understanding of a participant’s experience, attitude, or feeling requiring the need for follow-up. However, again, the purpose here is to provide cueing of the memories, experiences, associations, and so forth related to the phenomenon of interest and then to probe for further elaboration. A participant’s interview is minimally guided by the few prompts and, thus, he or she does have a degree of freedom to verbalize information that is unexpected by the researcher.
Third, participants might not be comfortable in the situation or have experience thinking aloud, potentially limiting the amount of rich data. Providing practice thinking aloud and verbalizing one’s thoughts as they view a given statement is recommended prior to beginning the task. Additionally, there is potential for observation or reactivity effects, if participants act differently than they normally would due to the presence of an observer or interviewer. This effect could result in a threat to the internal validity of the data (Onwuegbuzie, 2003). For instance, providing socially desirable answers when responding to the survey items is a common phenomenon and potentially more likely to occur if responding aloud. One way to minimize the reactivity effect is to spend time establishing a sense of trustworthiness before beginning the task (Glesne, 2006), especially if asking about topics of a sensitive nature such as one’s experience with peer rejection. Also, I find that participants tend to demonstrate more relaxed body language and elaborate after engaging with a few items, supporting the importance of practicing responding aloud to a set of items before responding to the items of interest.
Fourth, divergence might occur between an answer choice selected for an item and the elaboration provided by a participant. This divergence can cause a barrier when analyzing the data and drawing inferences about participants’ experiences, attitudes, or feelings. For example, this sixth-grade student rated his agreement low at
Even when accounting for the limitations inherent in this method, this adaptation of the cognitive pretesting protocol can provide an additional data collection tool for qualitative researchers to consider. This method of presenting statements in the form of a survey has the potential to instigate and to cue participants’ memories that might not be otherwise elicited when using more general open-ended interview questions. Further, this method has the potential to assist participants in verbalizing their thoughts for those who are less vocal when presented with more open-ended prompts. As I generated this idea, I questioned the unique contribution, asking myself, “How is what I am proposing different from the traditional think-aloud method used for decades?” My answer to this question is that the difference is the notion of using prompts and presenting statements in a familiar format, a survey. Then, I questioned how my idea was unique from what Karabenick et al. (2007) already outlined.
The response to my own question was that the protocol is the same but the purpose of the method and approach to analysis differs, advancing the development of qualitative methods. The purpose shifts from having participants think-aloud as they complete a survey to evaluate score validity to using the think-aloud protocol when responding to a survey as a medium for eliciting participants’ experiences with a phenomenon. Analyzing the data shifts from focusing on how close the verbalizations at an item level agreed with the intended meaning to analyzing the verbalizations as a whole across the survey.
I encourage others to consider whether the cognitive pretesting method traditionally used for informing the score validity of survey items might be applied for alternative research purposes and to test further the proposed application with populations beyond adolescents. One example alternative purpose in research or in the clinical practice of teaching is to apply this method to gain insight into students’ misconceptions about the concept they are learning. Questioning strategies and think-aloud tasks are common methods used to reveal misconceptions held by students. A unique alternative approach might be presenting students with a survey consisting of a series of statements (or other form of stimuli) representing a realm of common misconceptions and facts related to the topic under study. By asking students to think-aloud as they rate how strongly they disagree or agree with the statements in a survey form, a researcher or practitioner might gain deeper insight into how deeply a student holds a misconception.
