Data analysis
The qualitative data were coded and categorized following the steps in Braun & Clarke’s thematic analysis to identify motivational factors and experiential themes. Braun & Clarke’s framework for thematic analysis consists of six phases: familiarizing with the data, initial coding, searching for themes, reviewing themes, defining themes, and producing the report [Furthermore, an average was calculated for their motivation score for participating and their motivation to continue participating in the study. These two scores were compared to evaluate if the motivation for participation changed over time and if the two randomization groups differed in their motivation to continue participation in the CryoPac trial.
