RTI International has conducted many studies involving field data collection on laptop computers. Most of these Computer Assisted Personal Interviews (CAPI) are conducted in respondent’s homes and then data is transmitted to RTI. While collecting data for researchers, sensitive personal information is often provided by respondents. This data should be protected on the laptops and during transmission.
There are different ways to protect collected information. This paper describes an easy way to do that by using Blaise instrument with alien routers and procedures in Manipula setup to:
• Enter sensitive data outside of Blaise interview;
• Call external application to electronically obtain proof of respondent consent or other sensitive information;
• Download GPS data from a GPS-tracking device at the end of the interview.
Examples of code in Blaise instrument and Manipula setup are provided in this paper along with description of the external applications used during Blaise interviews.
