Evidence and practice: a review of vignettes in qualitative research.

Background: Developing and working through a PhD research study requires tenacity, continuous development and application of knowledge. It is paramount when researching sensitive topics to consider carefully the construction of tools for collecting data, to ensure the study is ethically robust and explicitly addresses the research question.

Aim: To explore how novice researchers can develop insight into aspects of the research process by developing vignettes as a research tool.

Discussion: This article focuses on the use of vignettes to collect data as part of a qualitative PhD study investigating making decisions in the best interests of and on behalf of people with advanced dementia. Developing vignettes is a purposeful, conscious process. It is equally important to ensure that vignettes are derived from literature, have an evidence base, are carefully constructed and peer-reviewed, and are suitable to achieve the research's aims.

Conclusion: Using and analysing a vignette enables novice researchers to make sense of aspects of the qualitative research process and engage with it to appreciate terminology.

Implications for practice: Vignettes can provide an effective platform for discussion when researching topics where participants may be reluctant to share sensitive real-life experiences.
