5. P.Mean: Justifying the sample size in a qualitative research study (created 2011-11-22). I was asked to help justify the sample size for a qualitative research study. When the goals of a study are qualitative, the sample size justification is also qualitative.

Abstract: "Much qualitative research is interview based, and this paper provides an outline of qualitative interview techniques and their application in medical settings. It explains the rationale for these techniques and shows how they can be used to research kinds of questions that are different from those dealt with by quantitative methods. Different types of qualitative interviews are described, and the way in which they differ from clinical consultations is emphasised. Practical guidance for conducting such interviews is given."

Abstract: "This article presents the results of a qualitative study (grounded theory) comparing nursing practice in corrections in both France and Canada. In Canada, nurses work as both agents of care and agents of social control. In contrast, French legislation has separated the responsibilities of health care and corrections. The effects of this split are illustrated, and the French model examine for important perspectives for restructuring nursing services in Canada." [Accessed October 26, 2010].

BMC Medical Research Methodology. 2011;11(1):128. Abstract: "BACKGROUND: Qualitative methodologies are increasingly popular in medical research. Grounded theory is the methodology most-often cited by authors of qualitative studies in medicine, but it has been suggested that many 'grounded theory' studies are not concordant with the methodology. In this paper we provide a worked example of a grounded theory project. Our aim is to provide a model for practice, to connect medical researchers with a useful methodology, and to increase the quality of 'grounded theory' research published in the medical literature. METHODS: We documented a worked example of using grounded theory methodology in practice. RESULTS: We describe our sampling, data collection, data analysis and interpretation. We explain how these steps were consistent with grounded theory methodology, and show how they related to one another. Grounded theory methodology assisted us to develop a detailed model of the process of adapting preventive protocols into dental practice, and to analyse variation in this process in different dental practices. CONCLUSIONS: By employing grounded theory methodology rigorously, medical researchers can better design and justify their methods, and produce high-quality findings that will be more useful to patients, professionals and the research community."

Alicia O'Cathain, Jon Nicholl, Elizabeth Murphy. Structural issues affecting mixed methods studies in health research: a qualitative study. BMC Medical Research Methodology. 2009;9(1):82. Abstract: "BACKGROUND: Health researchers undertake studies which combine qualitative and quantitative methods. Little attention has been paid to the structural issues affecting this mixed methods approach. We explored the facilitators and barriers to undertaking mixed methods studies in health research. METHODS: Face-to-face semi-structured interviews with 20 researchers experienced in mixed methods research in health in the United Kingdom. RESULTS: Structural facilitators for undertaking mixed methods studies included a perception that funding bodies promoted this approach, and the multidisciplinary constituency of some university departments. Structural barriers to exploiting the potential of these studies included a lack of education and training in mixed methods research, and a lack of templates for reporting mixed methods articles in peer-reviewed journals. The 'hierarchy of evidence' relating to effectiveness studies in health care research, with the randomised controlled trial as the gold standard, appeared to pervade the health research infrastructure. Thus integration of data and findings from qualitative and quantitative components of mixed methods studies, and dissemination of integrated outputs, tended to occur through serendipity and effort, further highlighting the presence of structural constraints. Researchers are agents who may also support current structures - journal reviewers and editors, and directors of postgraduate training courses - and thus have the ability to improve the structural support for exploiting the potential of mixed methods research. CONCLUSIONS: The environment for health research in the UK appears to be conducive to mixed methods research but not to exploiting the potential of this approach. Structural change, as well as change in researcher behaviour, will be necessary if researchers are to fully exploit the potential of using mixed methods research." [Accessed December 15, 2009].

4. Stats: Reviewing a paper on qualitative data analysis (March 11, 2007). I was asked by BMJ to review a paper that involved a qualitative data analysis. These reviews are confidential, so I don't want to describe the paper in any detail. It is worthwhile, however, to note some of the standards that others have suggested for assessing the quality of a qualitative data analysis. This is important for a peer-reviewer like myself. I need to be able to assess whether the authors have produced a result that is sufficiently rigorous to merit publication.

3. Stats: Using focus groups to bridge the gap between research and practice (December 14, 2006). The Injury Prevention journal published a nice article on how to use focus groups to bridge the research-practice gap, ip.bmj.com/cgi/content/full/12/6/373, along with an associated commentary, ip.bmj.com/cgi/content/full/12/6/357. This is a very nice article with the full free text available on the web. It has an excellent bibliography and many of the references also have full free text on the web. The authors followed a series of steps that they argue can be readily generalized to other safety issues.

2. Stats: Planning a qualitative research study (July 6, 2004). Someone asked me for some specific advice on how to design a qualitative study. I love qualitative research. I think people should be using this mode of research more often. But I have to admit that I have little first hand experience in this area. I can make some general comments but no specific recommendations.

1. Stats: Focus groups and qualitative research (April 13, 2004). A student is giving a talk on focus groups and asked me a few questions about my attitude towards them. I think focus groups are great. They give you a richer picture of the data and can often supplement quantitative studies.
