Intercoder Reliability in Qualitative Research: Debates and Practical Guidelines

Evaluating the intercoder reliability (ICR) of a coding frame is frequently recommended as good practice in qualitative analysis. ICR is a somewhat controversial topic in the qualitative research community, with some arguing that it is an inappropriate or unnecessary step within the goals of qualitative analysis. Yet ICR assessment can yield numerous benefits for qualitative studies, which include improving the systematicity, communicability, and transparency of the coding process; promoting reflexivity and dialogue within research teams; and helping convince diverse audiences of the trustworthiness of the analysis. Few guidelines exist to help researchers negotiate the assessment of ICR in qualitative analysis. The current article explains what ICR is, reviews common arguments for and against its incorporation in qualitative analysis and offers guidance on the practical elements of performing an ICR assessment.
