Consulting for the conduct of a victimization and perception survey

The Inter-American Development Bank (IDB) is calling on specialized firms for the operational design, field implementation, processing and delivery of databases for a survey of victimization and perception of security in urban areas of Honduras. The study includes a rigid probabilistic design and a multimode experimental component.

1. Sample design and experimental component
Experimental approach: Random assignment of dwellings in equal proportions (1/3) to three modalities for the main questionnaire: face-to-face (CAPI), telephone (CATI) and self-administered by WhatsApp. They all begin with a contact and brief face-to-face questionnaire.

- Target population: Heads of household or spouses over 18 years of age. Minimum effective sample of 6,280 complete surveys (~2,093 by mode and 50/50 gender balance).

- Representativeness: Four geographical domains (Tegucigalpa, San Pedro Sula, treated and control municipalities) through multistage sampling with INE cartography. Individual case replacement is not permitted; reserve UPM blocks are activated.

2. Piloting, ethics and operational safeguards
- Pilot survey: Comprehensive test in two municipalities to validate questionnaire flows, technological systems for sending/receiving, paradata and field connectivity.

- Ethical protocol: Informed consent in three stages, approval by an independent ethics committee (IRB) and homogeneous incentives per completed survey.

- Sensitive module: The Domestic Violence Module (VIF) will be applied exclusively in person. An emotional containment and referral protocol will be implemented (Line 911, prosecutors' offices).

3. Quality Control and Processing
- Digital monitoring: Mandatory registration of paradata (GPS, interview times, attempts) through CAPI/CATI in real time. The use of paper is prohibited.

- Field verification: Brief validation re-interviews to a minimum of 10% of the effective sample by independent supervisors.

- Deliverables: Delivery of filtered, validated and structured databases, accompanied by a methodological report and AAPOR rate reports.
