Title
DHS EdData Survey 2010
Data Collection Notes
Pre-test classroom training, held in September 2010, included introduction and study overview, general interviewing techniques, reviewing the four questionnaire types, anthropometry measurements and literacy test, questionnaire certifications exams, and administrative procedures.The pre-test training served as a train-the-trainers session for the coordinators who would conduct the larger full-scale training session. Data collection manuals were distributed to field staff about two weeks before training for review. Constructive feedback regarding interviewing techniques was provided to training participants throughout these exercises, which allowed the interviewers ample opportunity to address identified issues and learn proper interviewing, questionnaire marking, and storage techniques. After classroom training, practice interviews were conducted in surrounding areas over a seven-day period, after which revisions of the instruments, procedures, and training were done in accordance with lessons learned from the pre-test.
Training
For the full-scale training, held in March 2010, approximately 300 staff that included interviewers, field supervisors, field editors, and quality control interviewers were trained. The 2010 NEDS interviewers composed a subset of 2008 NDHS interviewers. NPC coordinators conducted the two-week classroom training for the full-scale survey with RTI staff on site to provide technical assistance as needed. The training also included practice interviews in neighborhoods in and around Keffi, using the questionnaire in English and the three local languages. Certification exercises were used to assess interviewers and ensure that they acquired the skills needed to correctly carry out their field duties.
After classroom training, teams were grouped into the three major Nigerian languages and English to conduct practice interviews using the language questionnaires. In addition, field supervisors, editors, and quality control (QC) interviewers received additional training to review proper auditing and field supervision techniques.
Data Collection
Through its previous experience with field surveys such as NDHS, NDES, and the Nigerian National Census, NPC has developed a field team structure that maximizes data quality. This same data collection team structure was used for the 2010 NEDS. Specifically, field interviewers were organized into survey teams, one for each of the 36 States, plus one for Abuja. NPC coordinated and supervised field operations for all 37 teams, each comprising 3 field interviewers, 1 field supervisor, 1 field editor, and 1 driver. In addition to the survey team, each State was assigned 1 QC interviewer. The QC interviewers, however, did not travel with the survey teams. Instead, they trailed the State teams to revisit and re-administer the full questionnaire during the first 2 weeks of data collection and for two weeks of every month of data collection thereafter. This was done in approximately 10 percent of all completed households. Field editors (1 per team) traveled with the survey team and edited all questionnaires in the field to ensure they were correct and complete. Field editors also observed field interviews where possible to ensure that the proper study protocols were followed. Field supervisors made team arrangements and sample assignments. Supervisors were responsible for the quality of the work carried out by the team, ensuring that interviewers followed administration protocols and controlling sample implementation.
Coordinators/trainers who conducted the training for the full-scale survey also oversaw field operations of the field activities in their two assigned States. They also monitored field activities in their States and were responsible for providing NPC’s NEDS Project Director with feedback and updates on field team activities.
After the data were keyed, coordinators reviewed data frequencies and tables to identify any data inconsistencies and errors. Coordinators periodically visited teams in the field to provide feedback and retraining as needed. To ensure a high level of quality and compliance with study protocols, RTI staff also conducted field observation visits. During these visits, RTI staff handled field operational problems and proposed solutions, providing feedback and encouragement to the interviewers.
