and the last interview was coded in phrases and sentences at a time (open coding). From this, a hierarchical coding scheme was developed enabling axial coding to occur, developing relationships between codes and sub-codes. Constant comparison was conducted during open and axial coding, which involved comparing the emerging codes and overarching theory within and across interviews (Strauss & Corbin 1998). Diagramming using organisational charts and Venn charts helped determine relationships between categories.
