Triangulation refers to the use of multiple methods or data sources in qualitative research to develop a comprehensive understanding of phenomena (Patton, 1999). Triangulation also has been viewed as a qualitative research strategy to test validity through the convergence of information from different sources. Denzin (1978) and Patton (1999) identified four types of triangulation: (a) method triangulation, (b) investigator triangulation, (c) theory triangulation, and (d) data source triangulation. The current article will present the four types of triangulation followed by a discussion of the use of focus groups (FGs) and in-depth individual (IDI) interviews as an example of data source triangulation in qualitative inquiry.

The Use of Triangulation in Qualitative Research

From Husserl to van Manen. A review of different phenomenological approaches.

PURPOSE We wanted to review and synthesize published criteria for good qualitative research and develop a cogent set of evaluative criteria. METHODS We identified published journal articles discussing criteria for rigorous research using standard search strategies then examined reference sections of relevant journal articles to identify books and book chapters on this topic. A cross-publication content analysis allowed us to identify criteria and understand the beliefs that shape them. RESULTS Seven criteria for good qualitative research emerged: (1) carrying out ethical research; (2) importance of the research; (3) clarity and coherence of the research report; (4) use of appropriate and rigorous methods; (5) importance of reflexivity or attending to researcher bias; (6) importance of establishing validity or credibility; and (7) importance of verification or reliability. General agreement was observed across publications on the first 4 quality dimensions. On the last 3, important divergent perspectives were observed in how these criteria should be applied to qualitative research, with differences based on the paradigm embraced by the authors. CONCLUSION Qualitative research is not a unified field. Most manuscript and grant reviewers are not qualitative experts and are likely to embrace a generic set of criteria rather than those relevant to the particular qualitative approach proposed or reported. Reviewers and researchers need to be aware of this tendency and educate health care researchers about the criteria appropriate for evaluating qualitative research from within the theoretical and methodological framework from which it emerges.

Evaluative Criteria for Qualitative Research in Health Care: Controversies and Recommendations

This article explores the research implications of using multi-methods within a broad qualitative approach by drawing on the experience of conducting two childhood obesity-focused qualitative studies of Australian children’s perceptions and experiences of place, space and physical activity. Children described and depicted their physical activities and experiences: in focus group interviews, by mapping their local, social and recreational spaces and by photographing their meaningful places, spaces and activities using a Photovoice approach. The authors describe, reflect on and critique their chosen research approach, discussing the value, utility and pitfalls associated with using multiple methods with children. The article concludes that using multiple methods in researching children’s experiences is a valuable approach that does not merely duplicate data but also offers complementary insights and understandings that may be difficult to access through reliance on a single method of data collection.

Multiple methods in qualitative research with children: more insight or just more?

Background. Focus group interviews are a method for collecting qualitative data and have enjoyed a surge in popularity in health care research over the last 20 years. However, the literature on this method is ambiguous in relation to the size, constitution, purpose and execution of focus groups.

Aim.  The aim of this article is to explore some of the methodological issues arising from using focus group interviews in order to stimulate debate about their efficacy.

Discussion.  Methodological issues are discussed in the context of a study examining attitudes towards and beliefs about older adults in hospital settings among first-level registered nurses, nursing lecturers and student nurses. Focus group interviews were used to identify everyday language and constructs used by nurses, with the intention of incorporating the findings into an instrument to measure attitudes and beliefs quantitatively.

Conclusions.  Experiences of conducting focus group interviews demonstrated that smaller groups were more manageable and that groups made up of strangers required more moderator intervention. However, as a data collecting strategy they are a rich source of information.

Focus groups as a research method: a critique of some aspects of their use in nursing research

Objective. To evaluate and critique reports in the nursing literature in the period 1990–1999 of the use of focus groups as a research method.

Methods. The articles were identified by a computerized search of the CINAHL database and subjected to critical review.

Findings. The result of the search was that very few articles were found that reported on a specific piece of research using the method. Methodological discussions were more common and these were sometimes at a somewhat superficial level without analysis or critique. The largest category of articles was concerned with service development projects. The research-based articles were found to be relatively unsophisticated in their use of the method, in particular in relation to data analysis and social interaction within focus groups. Terms such as ‘content analysis’ and ‘grounded theory’ were used in nonrigorous ways and incompatibility between the underlying research approach and implementation of the method was identified in the cases of phenomenology and grounded theory. Whilst selection of the focus group method was often justified in terms of the benefits that participant interaction could yield, this interaction was rarely reported or discussed in the articles. One author proposed a scheme for analysing this type of interaction, and this is recommended to future researchers as a possible framework for interaction analysis.

Conclusions. The article concludes by calling for more in-depth consideration at the research planning stages of the underlying assumptions of methodological approaches that may be used to underpin focus group research and methods to be used to analyse and report the data generated.

Pre-registration diploma students: a quantitative study of entry characteristics and course outcomes

Nurse education has been transformed over the last decade and continuing change is likely. Nurse educators are responsible for meeting the quality assurance standards of local stakeholders and student retention and progress are important aspects of this process. As part of a monitoring exercise, an enquiry was set up to review pre-registration selection and recruitment strategies and to establish if there were any significant relationships between the characteristics of pre-registration diploma entrants and their academic achievement or completion rates. A multi-factorial tree-based technique was used for this purpose. This is one of the first British studies to consider both academic performance and completion rates for pre-registration diploma students. Four cohorts (N = 355) were studied. There was marked heterogeneity in student characteristics with a wide age distribution, a significant proportion of mature entrants with previous care experience, and considerable diversity in terms of education. Education and age were significant predictors of academic achievement: entrants with a minimum of two A levels and mature women with recent study experience did particularly well. Younger recruits with modest educational qualifications on entry performed less well in their assessments of theoretical knowledge. Younger students tended to leave more regularly, and well-qualified entrants showed a greater tendency to complete, although these relationships were not statistically significant. Multi-factorial analysis demonstrated that organisational and course characteristics have a conjoint influence on course outcomes. Although the study is concerned with Project 2000 in the United Kingdom, there are lessons to be drawn concerning the selection and support of non-traditional recruits into nursing.

Pre-registration diploma students: a quantitative study of entry characteristics and course outcomes.

Background. The government of the United Kingdom is encouraging more flexible recruitment strategies to overcome the shortage of qualified nurses. Mature women returning to education, often after completing their families, are a major target, but there has been little evaluation of their experiences as higher education students of nursing.

Aim.  The aim of the study was to follow-up a previous quantitative study of mature women students’ outcomes on preregistration diploma courses in order to gain a deeper understanding of their experiences, and consider ways in which their needs might be addressed.

Methods.  Five focus groups were conducted in one higher education institution, and data were analysed using thematic analysis, assisted by the ‘spike’ feature of Word for Windows.

Findings.  Three major themes were identified: ‘Didn't know what to expect’, ‘Reality shock’ and ‘Learning the game’. Subthemes of ‘Learning the game’ were ‘Academic study’, ‘Practice placements and shift work’, ‘Managing the effect of course workload on domestic roles’, ‘Personal growth and changing relationships’, and ‘Support systems and friendships’.

Conclusions.  The findings are discussed in relation to reports of women's experiences in higher education in general. We conclude that the situation and needs of mature women preregistration nursing students are such that fundamental curriculum redesign is needed so that they can participate in higher education in ways that allow integration of their family and student lives, and permit them to benefit from the higher education experience in the same ways as younger students. The study is limited by its local nature, but the findings mirror those of other work, giving reassurance of its wider applicability. Recommendations are made for changes in the philosophy and organization of future programmes to improve their appropriateness and acceptability to mature women nursing students.
