Zaltman Metaphor Elicitation Technique (ZMET) in Qualitative Research

Introduction and Objectives: Zaltman (1996) believes that approximately 80 percent of all human communication is nonverbal. Tone, subtlety, and other speech qualities, along with other nonverbal cues such as body language, affect the meaning of spoken words. The use of nonverbal images alongside verbal conversations not only delivers more accurate messages but also helps to better understand people’s attitudes and perceptions (Van Dessel, 2005). Accordingly, the use of a technique that enables participants to convey their thoughts nonverbally and specifically through the use of metaphors enables the researcher to examine deep intellectual structures to learn more about how consumers think and feel.
ZMET uses images selected by participants in the interview environment to prompt them to explore complex issues that are extracted through metaphors. This innovative method allows participants to control the choice of images that reflect their thoughts and feelings. Selected images are explored using a set of interview techniques. Although quantitative studies provide detailed details on how to apply the ZMET process to academic research, Zaltman and Coulter (1995) suggest that certain steps should be followed. Coulter, Zaltman, and Coulter (2001) also emphasize the importance of four essential steps that ensure all the appropriate data is collected. However, the steps listed lack useful guidance on how each step works in practice. More concerningly, most of the studies published to date have been conducted by researchers who have been specially trained in the ZMET approach. For example, Catchings-Castello (2000) has noted that Zaltman seeks to promote the practice with a positive spirit and with a desire to expand his research by others. However, the specific nature of this technique and the stated limitations can prevent its wider use and application.
Therefore, the present study has tried to use this technique to lead researchers to a deeper understanding of its applications in qualitative research and to provide solutions to facilitate the use of ZMET in academic studies. By examining the challenges and opportunities available, this research explains the benefits of this method and shows how it can be used to extract richer and more meaningful data in various fields. It is hoped that this research will enrich the research literature in this field.
Research Method: This study examines and analyzes the Zaltman metaphor elicitation technique in qualitative research using a descriptive-analytical approach. The study is designed in several stages, and its main goal is to gain a deeper understanding of this method in the field of qualitative research. In the first step, the concept of ZMET is examined and analyzed. For this purpose, authoritative scientific sources, research articles, and reference books related to this technique are used. In this section, key definitions and concepts related to ZMET are examined comprehensively. Also, the history and philosophical foundations of this technique are carefully analyzed to determine its theoretical and practical dimensions well. This analysis includes examining the effects of various theories on the development of this method and identifying its historical milestones.
In the next steps, the basic principles and various aspects of the ZMET methodology are examined in more detail. This section includes analysis of data collection processes, data analysis methods, and challenges or limitations that researchers may face when using this technique. In addition, a comparison between paradigms, ontological foundations, and topics related to qualitative and ZMET research is presented to clarify the differences and unique characteristics of these two approaches. At the end, the collected materials and criticisms of the ZMET technique are presented from the perspective of researchers. The research attempts to provide new insights into the field by providing a comprehensive analysis of the ZMET methodology and to provide the basis for its wider use in qualitative research.
Findings: ZMET uses a ten-step one-to-one method based on images collected or taken by participants. Participants can take pictures from a camera or from available sources such as books, magazines, and so on. Coulter and Zaltman (1995: 40-43) propose the following ten-step process for performing the ZMET technique:

Storytelling: Each image must be described using a story or event.
Missing images: Participants are asked to describe the images they wanted to find but could not.
Image sorting: The participant is asked to sort the images into meaningful collections.
Construct elicitation: A modified version of the Kelly Repertory Grid technique and the laddering technique is used. In the Kelly Repertory Grid technique, the participant is asked to randomly select three images and explain how two images are similar and at the same time different from the third image. The process of construct elicitation continues until the resulting constructs are duplicated.
Most representative image: Participants indicate which image among all their images best represents their feelings.
Opposite image: The interviewer asks the participant about images that may describe the opposite of the task given to him.
Sensory images: The participant is asked to use other senses (non-visual senses) to express what represents the concept under consideration and what does not.
Mental map: All created constructs are reviewed using discussions and participants are asked to express if there is an idea that the interviewer has forgotten.
Summary image: The participant creates a summary image or assembly using their own images (sometimes added with images from an image bank) to express their important issues.
Vignette: The participant is asked to create a short film that helps communicate important topics related to the subject under consideration.

Discussion and Conclusion: In this study, by examining the key steps of ZMET and analyzing its benefits, it was shown that this method is especially efficient in the fields of marketing and branding; however, it can enter other scientific fields and provide a better understanding of people’s behavior in qualitative research that leads to more accurate results. The use of visual techniques not only helps to extract rich data but also allows researchers to identify mental patterns of people using metaphors. This, in turn, can help make strategic decisions in various areas related to human behavior. Therefore, the Zaltman technique not only overcomes the limitations of traditional methods but also enables researchers to reach deep into hidden meanings and emotions by providing a more comprehensive framework. These capabilities have made it one of the key tools in qualitative research that can be used in various scientific and practical fields.
However, there are also challenges in using ZMET. One of the most important challenges is the need for specific skills to conduct in-depth interviews and data analysis. Researchers should be familiar with the basic principles of this technique and have the ability to conduct interviews effectively. Also, time and cost constraints may affect the successful implementation of this method. The use of this non-traditional technique requires high skills and a deep understanding of the scientific foundations of this technique as an interviewer (Zaltman, 1996). Therefore, researchers who are planning to use this technique for the first time are advised to first conduct a small experimental study to gain the experience necessary for the optimal implementation of this method. After achieving a level of competence and accuracy in the successful application of this technique, they can conduct more studies with larger samples to more comprehensively examine the objectives of their research.
Finally, given the growing importance of a deeper understanding of people’s behavior in today’s competitive world, ZMET can play an important role in developing marketing strategies and other scientific fields. It is hoped that this research will be able to lay the groundwork for further research in this area and encourage researchers to use the Zaltman metaphor elicitation technique to explore new insights.
