Abstract
Qualitative research methods are receiving increasing recognition in healthcare-related studies. Nonetheless, the debate among scholars continues regarding validity in qualitative research; that is, whether the tools, processes, and data used are appropriate. Therefore, this study aims to describe the development and content validation of a focus group discussion (FGD) interview guide, which was utilized to explore practices and factors that influence adolescents’ usage of the Nutrition Information Panel (NIP) for food choices. A methodological study was carried out to assess the content validity of the FGD interview guide through a two-stage process (i.e., development and validation). The FGD interview guide for this study was developed by the researchers following five essential steps: identification of research objectives, selection of topics and questions, development of the guide, expert evaluations, and a pilot test. The developed FGD guide was assessed by five content experts representing a range of disciplines, including nutritionists, academicians, a qualitative researcher, and a teacher. A pilot FGD was conducted using a setting and participant criteria similar to those that will be employed in the main study. The content validity index (CVI) value for the developed FGD guide is 0.938. Seven out of 13 questions were modified based on the experts’ recommendations, such as reviewing an item, splitting it into two if necessary, retaining its original syntax if it was already suitable, or adding some new items. Subsequently, the researchers refined the questions’ wording and structure based on the analysis from the pilot FGD. Probes were also added to several questions to elicit in-depth responses from the participants. The final version of the FGD guide consisted of 13 main items and probes. The content validity of the FGD interview guide used in the pilot study was affirmed by a panel of experts; hence, it was deemed to be a valid instrument for measuring adolescents’ use of the NIP in future studies. Further investigation is needed to improve assessments of procedural knowledge and to test the interview guide in other populations.

Summary
There has been an increasing interest in the use of qualitative research methods in healthcare-related studies, as evidenced by the growing number of published papers in the literature. Qualitative research investigates people’s experiences and the meanings they make of such experiences.[1] In the context of healthcare, qualitative research enables researchers to address questions that may not be answered by quantitative methods.[2] the only way to obtain information about patients’ and their families’ perspectives is to ask, listen, and learn from them, and to incorporate their responses into the delivery of care. Qualitative methods capture patients’ viewpoints and add a dimension to the relevant knowledge base that quantitative research alone cannot acquire.[3] a qualitative research method is ideal because of its emphasis on an individual’s personal life experiences.[4]
