Data checking and cleaning were done by the entire research team under the direction of the principal investigator. At the end of every field day, data were checked for completeness and consistency, and FGDs were transcribed. All relevant sources of data were considered to allow for triangulation. After transcribing and cleaning, data were converted to rich text format and entered into Nudist Nvivo, a package used for analysis of textual data. A code book was developed which was used for coding the text, after which searches related to adherence were run. Quantitative data were entered using the MS Access 2000 database, and descriptive and bivariate analyses were completed using SPSS version 11.01.
