A recently published study in the Journal of Medical Internet Research explored
the feasibility of using text messaging as a data collection tool to monitor an
infant feeding intervention program in rural China. The text messaging method
had reasonable data agreement and low cost, but a low response rate.
An effective data collection method is crucial for high
quality monitoring of health interventions. The traditional face-to-face data
collection method is labour intensive, expensive, and time consuming. With the
rapid increase of mobile phone subscribers, text messaging has the potential to
be used for evaluation of population health interventions in rural China. Further
research is needed to evaluate effectiveness of measures that can increase the
response rate, especially in collecting longitudinal data by text messaging.
