The first author then read all themes and subthemes to determine if they were present in each focus group, inter-rater agreement was excellent and substantial (Berne, Frisén and Kling, 2014). Disagreement with a focus group led to a substantial rating and a change in the names of two subthemes occurred (Berne, Frisén, and Kling, 2014). This proved effective as it ensured the accuracy of themes and sub-themes and the use of three researchers enhanced the credibility of the project.
