Use of real-time interactive voice response in a study of stress and alcohol consumption

Research output: Contribution to journalArticle

Abstract

Background: The goal of this study was to investigate whether Interactive Voice Response is a technology with which to perform real-time assessments of alcohol consumption and stress. Methods: Fifteen subjects (men and women) were recruited from a previous 4-year intervention study (n = 2,032). The Interactive Voice Response technique was based on mobile telephones. During 1 week, stress and alcohol were measured automatically 3 times daily. In addition, the subjects called the system at the start of the drinking session, and an automated hourly contact was established for the drinking period. Results: Of the data collection calls, 305 (97%) were answered. Real-time drinking was assessed 9 times of 9 (100%). The average length of the IVR assessment was only 28 seconds because of modified technology. Individuals with an estimated blood alcohol concentration above 0.1% under-reported drinking in their day-after reports by between 1 and 10 drinks. The same subjects had more pronounced stress reduction than those with lower BAC levels. Conclusion: Interactive Voice Response methodology offers a promising new technology for daily as well as real-time assessments.
