dRi develops the data collection tools in close conjunction with the partner, and in alignment with the research goals and/or project logical framework. Training sessions for the field teams result in further questionnaire refinement and elaboration, as survey questions are tested for bias-inducing language, logical errors and formatting mistakes. Partner representatives frequently attend these sessions and provide input where required, resulting in the finalization of the questionnaire and the survey manual. At the same time, dRi in-house team designs tablet-based survey tools (both CATI & CAPI) by following the questionnaire of the quantitative study.
