Survey Questionnaires & Interviews
Westat pioneered a touchscreen version of the audio computer-assisted self-interviewing (ACASI) method. Westat's ACASI consists of a computer that displays questions and answers, reads these through headphones to the respondents, and prompts respondents to simply touch their answer on the screen. ACASI's benefits include participant privacy and ease of use, as well as decreased study costs and increased data quality.
Westat is doing groundbreaking work on interactive voice response (IVR) applications that simulate natural conversation with telephone respondents. The system "speaks" the questions, understands the spoken responses, and stores them. Westat's work in IVR technologies has helped decrease costs in large data collection efforts.
