The second coder (ALW) was familiar with the aims of the study but had not personally met or interviewed the participants. The second coder also coded 100% of the data. For every place where the two coders did not agree on their initial code, they underwent a code negotiation and transcript review (Patton, 2002). Their initial agreement in coding was only 29%, but that rose to 100% after code negotiation. Much of the initial discrepancy in coding centered on the subcodes for frequency and timing of the intervention. Furthermore, both coders added codes that were not in the initial code book and that required additional discussion
