Can sample size in qualitative research be determined a priori?

by Altmetric Debate Can sample size in qualitative research be determined a priori? Julius Sim, Benjamin Saunders, Jackie Waterfield, Tom Kingstone

There has been considerable recent interest in methods of determining sample size for qualitative research a priori, rather than through an adaptive approach such as saturation. Extending previous literature in this area, we identify four distinct approaches to determining sample size in this way: rules of thumb, conceptual models, numerical guidelines derived from empirical studies, and statistical formulae.

Grounded Theory is used frequently and discussed often by qualitative researchers, and can be a very useful methodology for indepth analysis of data - yet it can be quite confusing for new researchers to learn about - partly because there are different variants and methods. Here, we provide a list of useful resources to help you get your head around grounded theory.

This paper provides a general guide to presenting qualitative research for publication in a way that has meaning for authors and readers, is acceptable to editors and reviewers, and meets criteria for high standards of qualitative research reporting across the board. We discuss the writing of all sections of an article, placing particular emphasis on how you might best present your findings, illustrating our points with examples drawn from previous issues of this Journal.

Unintended consequences of the ‘bushmeat ban’ in West Africa during the 2013–2016 Ebola virus disease epidemic

by Jesse Bonwitt, Michael Dawson, Martin Kandeh, Rashid Ansumana, Foday Sahr, Hannah Brown, Ann H. Kelly

This interesting article uses qualitative research to consider the impacts of the bushmeat ban, and consider whether illegalising bushmeat had the desired effect. Useful, interesting paper for anyone with an interest in the ebola virus and how to encourage behaviour change.

The grounded theory (GT) method is widely applied, yet frequently misunderstood. We outline the main variants of GT and dispel the most common myths associated with GT. We argue that the different variants of GT incorporate a core set of shared procedures that can be put to work by any researcher or team from their chosen ontological and epistemological perspective.

Saturation in qualitative research: exploring its conceptualization and operationalization

by Benjamin Saunders, Julius Sim, Tom Kingstone, Shula Baker, Jackie Waterfield, Bernadette Bartlam, Heather Burroughs, Clare Jinks

In this paper, we look to clarify the nature, purposes and uses of saturation, and in doing so add to theoretical debate on the role of saturation across different methodologies. We identify four distinct approaches to saturation, which differ in terms of the extent to which an inductive or a deductive logic is adopted, and the relative emphasis on data collection, data analysis, and theorizing.

This helpful presentation is the result of a workshop held in Durban by The Global Health Bioethics Network (course facilitators: Maureen Kelley, Patricia Kingori, Dorcas Kamuya, Mike Parker).

Conducting good, ethical global health research is now more important than ever. Increased global mobility and connectivity mean that in today’s world there is no such thing as ‘local health’. As a collection, these stories offer a flexible resource for training across a variety of contexts, such as medical research organizations, universities, collaborative sites, and NGOs.

Using Gender Analysis within Qualitative Research

by Research in Gender and Ethics (RinGs)

Gender analysis entails researchers seeking to understand gender power relations and norms and their implications, including the nature of women’s, men’s, and people of other gender’s lives, how their needs and experiences differ, the causes and consequences of these differences, and how services and polices might address these differences.
