Computer Assisted Telephone Interview [cati]
NBS in collaboration with the World Bank carried out the survey using mobile phones and captured data in tablet, which was later uploaded to the server after verification. Both teams worked together to design and program the instrument in Survey Solutions.
Two supervisors and five enumerators carried out the data collection. The supervisors were previously trained on how to carry out electronic data collection via telephone, and also on how to provide training to enumerators by the Poverty and Equity and the LSMS teams. In addition to the training that took place before the baseline data collection, the supervisors were oriented to the second-round survey on food security. Thereafter, the supervisors trained the enumerators for the round 2 questionnaire. Before the data collection started, the questionnaires were piloted in-house and the enumerators also called someone in their home area.
During the data collection, the supervisors were constantly present to monitor the data collection process. The supervisors also verified responses after the interviews before downloading the data to the server.
During the interview, the participants were told that they could drop out at any time or choose not to answer a given question. All the participants were given 300 Naira of call time to take part in the survey. The call credit was transferred the very next day. We expect this to have contributed to the very low rate of non-response.
During the course of the data collection process, three consistency checks were run to check that the length of the interviews were in accordance with the target time frame and to flag questionable entries during the data collection process
