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.
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.
Interactive Voice Response methodology offers a promising new technology for daily as well as real-time assessments.
