Chapter III: Methodology
A total of 1.5 hours were taken to train the intercoder. The total time used by the
intercoder to code all the presented units against his or her choice of categories was 2 hours and
55 minutes. Intercoder reliability using Cohen's kappa was 0.83. After the initial intercoder
reliability was assessed, a time was scheduled for this investigator and the same intercoder to
discuss the non-matched items. After discussion, the intercoder reliability for Cohen's kappa was
0.94. Familiarity with the nature of the material and capability to handle the categories in terms
of the data language reliably was helpful (Holsti, 1969; Krippendorff, 1980) but not a necessary
requirement for the intercoder. Constructs of participants' categories and subcategories, category
definitions, and examples are presented in Table 6, Table 7 and Table 8.
