A Free Audio-CASI Module for LimeSurvey

Harald Beier and Sonja Schulz (2015)

In: Survey Methods: Insights from the Field

Audio-enhanced computer-assisted self-interviewing (ACASI) has several advantages over computer-assisted self-interviewing without audio enhancement (CASI). Being able to listen to sound files of questions and answer options while proceeding through a questionnaire can increase interest in the survey, improve comprehension of survey questions and considerably lessen the burden of a self-administered interview, especially on target populations with reading difficulties. In addition, it has been argued that ACASI reduces social desirability bias. One problem in implementing ACASI is the lack of affordable and easily accessible software solutions supporting it. This paper introduces an ACASI module for the open-source software LimeSurvey. The module supports the commonest question types, can be integrated into existing installations of LimeSurvey with only minor effort and is available from the authors, free of charge.
