DRCC is seeking a mixed-methods study combining qualitative and quantitative research. Tenderers should propose a methodology but are expected to address: Quantitative strand – a survey capturing attitudes, norms and behaviours at scale, with a robust and representative sample of the target group. Qualitative strand – in-depth engagement (e.g. focus groups and/or interviews) to explore the meaning and context behind quantitative findings. Analysis and synthesis – integration of qualitative and quantitative findings into a coherent set of insights. Recommendations – practical, actionable recommendations for DRCC's prevention and education work. Tenderers should propose their own recommended sample sizes, recruitment approach and fieldwork methods, with rationale.
