From: Using discrete choice experiments to inform the design of complex interventions
Qualitative research step | Added DCE step | |
---|---|---|
1. Pilot testing in-depth interviews (IDIs) and participatory group discussions (PGDs) | (a) Debriefing qualitative research team; four rounds of pre-pilot individual interviews | |
↓ | (b) Finalization of pilot tool and experimental design | |
2. Qualitative research data collection: | ↓ | (c) DCE pilot interviews (n = 50) |
Njombe: 10 PGDs and 15 IDIs | ↓ | (d) Analysis of pilot data to obtain prior utility estimates (priors) used to generate the efficient experimental design |
Tabora: 10 PGDs and 15 IDIs | ||
(e) DCE survey: | ||
Njombe (n=159); Tabora (n=166) | ||
3. Intervention design | (f) Present and interpret qualitative and DCE results to tailor final VMMC demand creation intervention |
