Table 1 Process of data analysis

SA reads all transcripts in an iterative process to identify themes and sub-themes (variations in advisor experiences of providing relapse prevention treatments and variations in thinking within themes)

SA designs a framework (index) with themes and sub-themes and their working definitions

TC and AMc agree working definitions for the emerging themes and sub-themes

SA codes the transcripts for the themes. Data relating to each theme is assembled. TC and AMc independently read 10 randomly selected transcripts to see if they are being coded consistently

Working definitions for themes and sub-themes are refined. The framework (index) is re-structured to reflect the changes

SA re-codes the transcripts using the refined definitions.

TC and AMc check reliability of the data and interpretation of the findings at each stage of the process
