Data Collection Notes
**Training of Interviewers and Supervisors**
As part of the preparation and implementation of the survey, a ten-day training workshop was organized to ensure a consistent understanding of the questionnaires among all interviewers and supervisors. The workshop aimed to ensure the quality of the data collected by harmonizing the methods and techniques used to administer the questionnaires.
Training sessions were held in several strategic locations: Dabou, Abengourou, Yamoussoukro, Bouaké, Korhogo, Daloa, Soubré, and Man. Each location hosted two groups of participants to maximize the effectiveness of the training and facilitate a better understanding of the topics covered. This approach encouraged dynamic interaction between trainers and participants and strengthened the acquisition of the skills required to conduct the survey rigorously and professionally.
Through these sessions, interviewers and supervisors were trained in the tools and techniques required to ensure reliable data collection in accordance with established methodological standards. This training constituted a key step in ensuring the successful implementation of the survey and the production of data suitable for analysis and decision-making.
**Quality Control Procedures**
To ensure the quality of the data collected in the field, several technical quality control mechanisms were implemented at different levels. These measures were designed to ensure data integrity, consistency, and completeness. The main quality control procedures included:
- Consistency checks embedded in the data entry forms: To reduce data entry errors, outliers, and inconsistencies, consistency checks were built directly into the questionnaire data entry forms. These checks ensured that entered data complied with predefined logical rules and expected relationships between fields. This made it possible to immediately identify erroneous or inconsistent data before they were submitted or recorded.
- Data consistency and integrity control program: This program was designed to perform thorough checks of the data collected to ensure their consistency and completeness. The checks were carried out by supervisors and members of the survey technical committee. Their role was to review the data collected in the field, identify errors or inconsistencies, and correct them prior to final data processing.
- Field team monitoring program: This program was designed to monitor the progress of field data collection. It helped ensure that field teams adhered to the data collection schedule, identify difficulties encountered during fieldwork, and verify that established procedures were correctly applied. The program provided regular reports on team progress, enabling proactive management and adjustments where necessary.
