This paper attempts to explore the universal foundation on which the discourses on the validity criteria in qualitative research should be based, and further discuss in depth the scope and direction of an adequate validity criterion in qualitative research by critical examination of previous discourses. To establish the foundation for qualitative research, first of all, the concept of quality and qualitative paradigm were examined in terms of ontology and epistemology, especially focused on the works carried out by Aristotle, Kenneth and Boyd. Secondly, the earlier studies on the validity of qualitative research were critically reviewed in terms of the theoretical findings on the concept of quality and qualitative paradigm. The major results include the following: First, the true content of quality is defined as the 'what-ness' or essence of things perceived by subjects, and qualitative paradigm as adequate framework for qualitative research is comprised of two intrinsic modes: one is the mode of awareness and the other is that of expression. Second, qualitative researchers are able to reach to the higher level of validity by considering not only the subjectivity and the originality but also the sociality in drawing a conclusion through qualitative perception. Third, the trend of previous validity discourses can be firmly summarized as the effort to overcome the effect of quantitative research and acquire the true identity for qualitative research, which is subjectivity, and as the quest to compromise the tension between subjectivity and sociality. Finally, based on the findings, several research topics are suggested. For example, the more attention should be paid to the area of the expression of qualitative awareness as a way of overcome the tension between subjectivity and publicness.

The purpose of this research is to study the meanings and characteristics of qualitative research method in LIS. As the philosophy and epistemology of qualitative research are widely different from those of quantitative research, the meaning of validity and reliability must be interpreted in its ow9 structure and dimension. Essentially qualitative researchers seek to understand and interpret the world of others from their own viewpoints which basically tend to be subjective. Accordingly, qualitative researchers‘ understandings and interpretations are met with readers' subjectivity. By carefully analyzing the nature of qualitative research in LIS, I tried to point out some problems in terms of validity and reliability and practical strategies. Six problems issued in the qualitative research method are presented.

In the context of Korean educational research, the number of qualitative research studies has gradually increased since 2000. It has become one of the most important research methods today. The field of math education is no exception to this trend, and qualitative approaches are now becoming one of the main research methods. This increase in qualitative research has contributed to the provision of detailed information about educational practice, but at the same time, the overall level of credibility in the results of qualitative research seems to be lower than that of quantitative research. This study started with the problem consciousness that the number of qualitative studies is increasing in the field of mathematical education, but there is a lack of discussion on the methodology of applying qualitative research methods. In this study, among the papers published in the journal related to mathematical education, papers using a qualitative approach are analyzed focusing on cross-case analysis. Based on the analysis results, the tendency to use qualitative approaches is diagnosed, ways of improving the validity and trustworthiness of qualitative research results in the field of mathematical education are examined, and implications and suggestions are presented.

Qualitative research has become a growing area of interest among the Korean educational researchers for the last two decades. As a consequence, the number of studies based on qualitative methods has rapidly increased while the quality of qualitative research has not gained much credit among scholars in Korea. This study explores to current practice of qualitative approaches in mathematics education-related studies. With this in mind, this study also seeks ways to improve the validity and trustworthiness of qualitative approaches, and to present implications for the practical practice of qualitative approaches in mathematics education. To this end, a general trend was investigated by conducting a basic analysis of 13 papers that used qualitative approaches and published in Communications of Mathematical Education from 2019 to 2020. Of the 13 papers. Through the basic analysis, 6 out of 13 papers were selected as the object of qualitative text analysis. The result of this qualitative text analysis discusses issues related to the validity and trustworthiness of qualitative research in a detailed manner. In conclusion, based on the results of this qualitative text analysis, this study suggests several key points to keep in mind when applying qualitative approaches in the field of mathematics education in the future.

Purpose: This study was to examine the trend of qualitative study published by Korean Journal of Adult Nursing from 1989 to 2011, and to suggest future directions through identifying its strength and weakness. Methods: Ninety one published qualitative studies were analyzed focusing on research methodology and research themes using descriptive statistics. Results: During the last 22 years, the number of qualitative studies has rapidly increased and the methodology used to analyze qualitative data has been diversified. The most frequently used analytic method was a phenomenology (48.4%) and the frequency of conducting a content analysis has increased. The prevailing data collection settings were community (61.5%), followed by hospital (35.2%). Especially, many researches showed specific description on researcher's efforts to get validity and reliability of studies in individual studies presented within recent 10 years. However, it was noted that meta study using mixed methodology and secondary analysis of qualitative studies are rarely used and need to be facilitated. Conclusion: Nursing Researchers utilizing qualitative research should continuously make efforts to increase the validity and reliability of their studies and to find knowledges or strategies applicable to practice through using mixed methods or secondary analysis of individual studies.

This study explores actual conditions and experiences on the rigor of social welfare qualitative researchers in Korea by using a qualitative inquiry. To examine the actual conditions on the rigor, this study analyzes 2,112 articles published in 8 Korean social work journals from 1979 to 2006. And to explores the experiences of social welfare qualitative researcher on the rigor, this study analyzes the experiences of qualitative research by using individual interviews and focus group interviews. The characteristics of social welfare qualitative research in Korea tend to enlarge according to the needs by doctoral candidates, coexist with post-positivism and constructivism. The analysis of both quantitative and qualitative results show that the rigor of social welfare qualitative research is very important to secure the validity and control the quality of qualitative research. Based on these results, this study introduced concrete tasks related to secure the rigor of social welfare qualitative research in Korea.

Qualitative research methodology has been applied with increasing frequency in various fields, including in healthcare research, where quantitative research methodology has traditionally dominated, with an empirically driven approach involving statistical analysis. Drawing upon artifacts and verbal data collected from in-depth interviews or participatory observations, qualitative research examines the comprehensive experiences of research participants who have experienced salient yet unappreciated phenomena. In this study, we review 6 representative qualitative research methodologies in terms of their characteristics and analysis methods: consensual qualitative research, phenomenological research, qualitative case study, grounded theory, photovoice, and content analysis. We mainly focus on specific aspects of data analysis and the description of results, while also providing a brief overview of each methodology's philosophical background. Furthermore, since quantitative researchers have criticized qualitative research methodology for its perceived lack of validity, we examine various validation methods of qualitative research. This review article intends to assist researchers in employing an ideal qualitative research methodology and in reviewing and evaluating qualitative research with proper standards and criteria.

Purpose: The purpose of this study was to analyze reports of qualitative research published in Journal of Korean Academy of Fundamentals of Nursing (JKAFN). Methods: Twenty four qualitative research studies using in-depth interviews and focus group interviews published in JKAFN from 1994 to 2014 were selected for analysis. Chosen reports were analyzed by consolidated criteria for reporting qualitative research (COREQ), which is a reporting guideline for qualitative research. COREQ consists of 32 items and 3 domains. Results: In the 1st domain, the relationship of researchers and research participants, bias and understanding of the researchers on the study phenomenon were analyzed less than other items. In the 2nd domain, methodological research was carried out across various qualitative studies, but the description of the research environment and research questions for the interview guidelines was insufficient. In the 3rd domain, research results and data were consistent, but data showing opposing content and explanations of negative practices were not done at all. Conclusion: These results indicate a need for the development of evaluation tools for qualitative research and items should be added to improve the reliability and validity, research should be related to the ethics in the framework of the COREQ.

This study discusses the nature of data-interpretation process in the perspective of modern hermeneutics and explores its methodological implications for qualitative research on the life of children. Discussions center around the basic concepts of modern hermeneutics, such as the conceptual distinctions between understanding and explanation, the intersubjective reality constituted between the child's horizon and the researcher's, the concept of the hermeneutics circle and the importance of the openness of language in understanding children's lifeworld. The conclusions are made as follows: First, the concept of "understanding", which is the basic concern of qualitative research on children, has a much different meaning from that of "explanation" in quantitative research. The task of understanding lies in interpreting the lived meaning in context as experienced by children in all its complexity. Second the researcher's subjectivity in the interpretation process has a dual function in that it can produce a faulty hermeneutics circle and yet it provides the researcher with the strong momentum to open up her understanding towards a deeper and wider level. Third, the reliability and the validity of qualitative research should be discussed within the interpretation process itself in that interpretation in qualitative research is guided basically by the researcher's internal dialectic: between data (text) and her subjectivity. Lastly, the language in interpretive research should be open and free in terms of style in order to present a fuller and richer description of children's lifeworld and the delicate textures of their lived meanings.

Objectives: It is critical to assess community readiness (CR) when implementing childhood obesity prevention programs to ensure their eventual success and sustainability. Multiple tools have been developed based on various conceptions of readiness. One of the most widely used and flexible tools is based on the community readiness model (CRM). This study aimed to adapt the CRM and assess the validity of a community readiness tool (CRT) for childhood obesity prevention programs in Iran. Methods: A Delphi study that included 26 individuals with expertise in 8 different subject areas was conducted to adapt the CRM into a theoretical framework for developing a CRT. After linguistic validation was conducted for a 35-question CR interview guide, the modified interview guide was evaluated for its content and face validity. The quantitative and qualitative analyses were performed using Stata version 13 and MAXQDA 2010, respectively. Results: The Delphi panelists confirmed the necessity/appropriateness and adequacy of all 6 CRM dimensions. The Persian version of the interview guide was then modified based on the qualitative results of the Delphi study, and 2 more questions were added to the community climate dimension of the original CRT. All questions in the modified version had acceptable content and face validity. The final CR interview guide included 37 questions across 6 CRM dimensions. Conclusions: By adapting the CRM and confirming linguistic, content, and face validity, the present study devised a CRT for childhood obesity prevention programs that can be used in relevant studies in Iran.
