Abstract

Background:

Interactive voice response technology (IVR) allows investigators to collect daily measures of drinking, medication adherence, mood, and other treatment-relevant variables that may change day to day during a clinical trial. Despite these advantages, no published studies have used IVR in alcohol pharmacotherapy trials.

Methods:

Subjects provided daily data via IVR during the 12-week treatment period. Seven subjects completed the trial.

Results:

We found a high level of participant adherence to the IVR protocol, higher levels of drinking reported by IVR than by a commonly used recall method, and distinct within-day associations between daily mood and alcohol consumption: these could not be obtained through traditional assessment methods.

Conclusions:

IVR seems to be feasible for the collection of daily indicators of treatment outcomes and processes in pharmacotherapy studies among problem drinkers.
