A Discussion of the Concepts of Validity and Reliability in Qualitative and Quantitative Research

The global medical and nursing research community has increasingly embraced qualitative research approaches, recognizing the additional benefits they provide to the investigation process. Qualitative research explores the intricate details of human behavior, attitudes, and experiences, emphasizing the exploration of nuances and context. Ensuring trustworthiness is crucial in establishing the credibility and reliability of qualitative findings. This includes elements such as credibility, transferability, dependability, and confirmability. Several papers have discussed concerns regarding the rigor of qualitative health services research and have provided guidelines and checklists for publishing and conducting qualitative research. The key criteria for ensuring the quality of qualitative research include credibility, achieved through extended involvement, persistent observation, and triangulation; transferability, achieved through comprehensive and detailed explanations; dependability, achieved through rigorous documentation and the creation of an audit trail; and confirmability, achieved through peer debriefing, member checking, and reflexive journaling. Establishing reliability in qualitative research is crucial for influencing future research paths and advancing cumulative knowledge. Trustworthy qualitative research findings are also important for informing policy decisions and improving the provision of services in various fields. While qualitative research has limitations, such as subjectivity and resource constraints, the methodical application of measures to ensure trustworthiness greatly enhances the precision and reliability of qualitative research. These measures also encourage transparency and critical evaluation by the scholarly community.

This article aims to reflect on scientific validation strategies in qualitative research in the light of translational theory in nursing. It is a reflection based on translational theory applied to nursing in strategies for validating qualitative studies. From this angle, validation is recognized as an adaptable construct, capable of eliciting/favoring an understanding of the subjectivity of the target audience in its relationship with the object of interest/study/research. The potential for advancing the science-profession lies in the interdisciplinary confluence of validation mechanisms, qualitative studies, the translational perspective, and nursing research. This confluence has the capacity to extend beyond theoretical and epistemological aspects. However, it is crucial to emphasize its profound, expressive, and relevant impact on the construction of scientific evidence. This impact aims to enhance the rigor and reliability of qualitative research, thereby bolstering its credibility and applicability in clinical practice.

The Coming of Age for Qualitative Research: Embracing the Diversity of Qualitative Methods

The purpose of this focused issue is to advance understanding of qualitative research methods in the international business context. Debates on qualitative research methods in the key international business (IB) journals have been rare. There has been no focused issue on this topic previously, either in mir or in other journals in the field, making this a 'special' issue. During the process of editing a recent handbook on qualitative research methods (Marschan-Piekkari/Welch 2004), we realized that while this collection covered many topics, often for the first time in the IB field, there were many others still outstanding. There was thus scope for continuing a dialogue about qualitative methods in the IB research community. The challenge of making qualitative research count in the quantitative world of IB remains. Qualitative research is difficult to define, since the term encompasses many different research traditions, research strategies and methods for data collection and analysis (Prasad 2005). A typical definition is that everything non-numerical is qualitative research (Marschan-Piekkari/Welch 2004, p. 19). However, even this very simplistic definition soon breaks down, since research strategies which are typically considered to be qualitative, such as case studies, can combine numerical with non-numerical data (Hurmerinta-Peltomaki/Nummela 2004). There is also no clear divide between qualitative and quantitative research in terms of research traditions, with much qualitative research in management and IB sharing the positivist assumptions of quantitative research (Prasad/Prasad 2002). This focused issue is not about reporting the empirical findings of IB studies applying qualitative methods; rather it is about the process of undertaking qualitative research in the IB field. Of course, there is a large volume of literature on qualitative research methods already. However, we would argue that the IB context warrants special treatment. As the authors of this focused issue discuss, the distinctiveness of the field stems from its multiple linguistic and cultural settings; organizational complexity; and its intellectual roots in post-War academic institutions in the USA. These issues receive little treatment in general texts on qualitative methodology. There has been some methodological debate in previous issues of mir. Earlier articles in mircan be grouped into three categories: first, reviews of existing methodological practices in IB publications (e.g., Cavusgil/Das 1997, Nasif et al. 1991); second, proposals for new quantitative techniques (e.g., the use of key informants in cross-cultural studies, as proposed by Lenartowicz and Roth 2004 and a linguistic-based measure of cultural distance as developed by West and Graham 2004); and third, calls for new methodological approaches (Boddewyn/Iyer 1999). The absence of qualitative research methods in this debate perhaps reflects the limited amount of empirical qualitative research published in this journal. A recent analysis of mir issues between 1990 and 1999 revealed that only 5 percent of articles published in this period used qualitative methods (Welch/Welch 2004). This focused issue is therefore a response to those, such as Boddewyn and Iyer (1999) in this journal, who have called for alternatives to surveys and secondary data analysis. This focused issue attracted 39 submissions from more than 15 countries. Given that there have been limited outlets for methodological articles in IB, this is a considerable number. It perhaps suggests a level of interest to which IB journals have not responded to date. Of the total number of submissions, 11 were selected for review. On the basis of reviewers' comments, six of these papers were ultimately rejected. The final five papers underwent two and, in some cases, up to four rounds of revisions. In selecting the articles, we used the following criteria: appropriateness of the topic for the focused issue; demonstrated knowledge of IB and methodological literature; quality of argument; originality and innovativeness of the contribution to IB methodology; organization and clarity of the paper; and potential application to research practice in IB. …

The vast majority of radiography research is subject to critique and evaluation from peers in order to justify the method and the outcome of the study. Within the quantitative domain, which the majority of medical imaging publications tend to fall into, there are prescribed methods for establishing scientific rigour and quality in order to critique a study. However, researchers within the qualitative paradigm, which is a developing area of radiography research, are often unclear about the most appropriate methods to measure the rigour (standards and quality) of a research study. This article considers the issues related to rigour, reliability and validity within qualitative research. The concepts of reliability and validity are briefly discussed within traditional positivism and then the attempts to use these terms as a measure of quality within qualitative research are explored. Alternative methods for research rigour in interpretive research (meanings and emotions) are suggested in order to compliment the existing radiography framework that exists for qualitative studies. The authors propose the use of an established model that is adapted to reflect the iterative process of qualitative research. Although a mechanistic approach to establishing rigour is rejected by many qualitative researchers, it is argued that a guide for novice researchers within a developing research base such as radiography is appropriate in order to establish the credibility and trustworthiness of a qualitative study.

Over the years the research endeavours in social sciences have been directed towards producing profound discoveries about humankind and the society they live in. Now-a-days qualitative research has been flourishing in many fields of the social sciences. Rapid social change and the resulting diversification of life scenarios are increasingly confronting social researchers with new social contexts and perspectives. There is a specific relevance for qualitative research to the study of social contexts and life situations. This has lead to the development of several social theories and social research methods which have still continued to develop in order to understand the diverse social problems. The challenge for social scientists and researchers worldwide is to continue in the search for a unified consensus on what methodology is to be adopted for research for meeting the emerging diverse needs of humankind and the society. This thought has led to the proliferation of pluralism or multi-method research in which the researcher synthesizes multiple research methodologies in order to study social problems in a holistic way. This concept of pluralism in research has to a greater extend subverted methodological tribalism which had existed till the recent past. This paper focuses on the philosophical assumptions as guidelines to research paradigms have influenced the development of social research theory and social research methods towards pluralism. This paper intends to explore pluralism in qualitative Social Science researches as it may be applied methodologically and philosophically. In this context, the paper heeds a thought on refocusing pluralistic qualitative research in terms of its needs and demands based on the level and depth of the study undertaken. Key Terms: Qualitative research, methodological pluralism, research paradigms, philosophical assumptions

The dichotomous debate between objectivity and subjectivity in Social Sciences and the differences between qualitative and quantitative approaches in research are related to the strong demand for validation and accreditation of studies. Thus, the main objective of this paper is to discuss quality in qualitative research, through a systematic analysis of the typologies of triangulation strategy, highlighting the following quality dimensions in research: reliability, credibility, transferability and confirmability. There is a considerable amount of research about quality in qualitative research, as well as about triangulation. However, the main differentiator of this paper is the systematic presentation of triangulation typologies, which allow for the improvement of quality in qualitative research. The authors believe that the focus on "how to" improve quality, and not quality itself, makes this paper original. Among the main findings, it can be highlighted the effort to systematize and present guidelines in order to improve credibility in qualitative research, by means of the triangulation strategy presented in a framework that will allow the reader to have a better understanding of the proposals in this work. The authors understand that the main implication of this paper is mainly in providing guidance to researchers, particularly those dealing with qualitative research, on how they could improve the quality of their research.

Digital features like virtual reality have hardly been used in the framework of data collection in qualitative social work research. Virtual reality holds specific promise because it allows the immersion of participants in a situation and has the potential to strengthen the ecological validity of data. In this light, we examined the use of a virtual reality serious game in qualitative in-person interviews in the framework of a prevention-oriented HIV social research project. We designed and developed an immersive virtual reality serious game, and integrated it into 24 problem-centred in-person interviews. The integration was feasible, and the virtual reality serious game was well accepted. It prompted participants to elaborate their lived experiences more extensively and in depth. Participants subsequently recalled episodes they had not mentioned before, complemented their narratives and brought up new topics. The atmosphere became less formal, and participants were even more communicative. The use of virtual reality seems to have the potential to open up new perspectives, broaden epistemic possibilities and complement the qualitative methods used to investigate, in particular, verbal and non-verbal communication and interaction processes. From an ethical perspective, the use of virtual reality should be well reflected upon regarding possible after-effects for the participants.

The idea of reliability in research refers to the repetition or reinforcements of the degree of findings given under the same experiment condition performed by the other researchers and thus leading a wider research community to accept the proposed

This chapter is aimed to discuss the ethical issues of qualitative research. Because of nature and forms of qualitative research, ethical issues, validity and reliability of qualitative research has been discussed in many research investigations. By nature ethical issues in qualitative research are vague and inherent. These ethical issues of qualitative research have been discussed by researchers and experts from different areas. This chapter discusses the focal points of ethical issues. The interactions and the interest of concerned parties of qualitative research form the ethical issues. Moreover, different views (Positivistic and relativistic) of ethical issues of qualitative research raise some complexity. This chapter discusses the various issue of qualitative research from various perspectives. Researchers' opinions on the ethical issues of qualitative research have been discussed, and after that the chapter has been arranged with the basic ethical issues of qualitative research as the area is vary vast.

We provide an overview of qualitative methods used in physics education research, along with numerous illustrative examples from the literature. We outline the connection between broad research ideas and more specific research questions, and discuss how they both guide the study design. We describe various forms of interviews used in PER, along with detailed illustrations of each type drawn from both older and newer research literature. We examine other data sources such as surveys, artifacts, electronic sources, and observations, and briefly discuss the initial processing of the research data. We describe in considerable detail various approaches to coding and analyzing qualitative data, with another set of illustrative examples from the PER literature. We provide a brief overview of theoretical perspectives in PER, along with a summary discussion of validity and reliability in qualitative research.
