Title PDAs in socio-economic surveys: instrument bias, surveyor bias or both?

Abstract

It is very likely that electronic means of data collection will become a standard for socio-economic surveys in the near future. As surveys move from paper form to personal digital assistants (PDAs) or tablets, there is a need to evaluate if such a shift will affect the quality of the data. To explore the potential biases that data collection through PDAs may generate, we use the third wave of Young Lives-Peru to randomly assign survey respondents between PDA-based questionnaires and paper-based questionnaires. The study shows that data collected through PDAs has a higher level of agreement when compared to paper-based responses. However, there are a number of situations where paper-based questionnaires do not easily translate to PDA-based questionnaires. In addition, the study highlights the need to improve training as different surveyor's characteristics (age, gender, education, etc.) may also be correlated with some observed differences between PDA and paper-based questionnaires.
