Daily telephone monitoring compared with retrospective recall of alcohol use among patients in early recovery.

Most studies comparing frequent self-monitoring protocols and retrospective assessments of alcohol use find good correspondence, but have excluded participants with significant comorbidity and/or social instability, and some have included abstainers. We evaluated the correspondence between measures of alcohol use based on daily interactive voice response (IVR) telephone monitoring and a 28-day modification of the Form-90 (Form-28). Participants were 25 outpatients with alcohol use disorder and significant PTSD symptomatology . Overall correlations between the IVR and Form-28 on days drinking and total standard drink units (SDUs) were strong for the entire sample and the subsample of drinkers (n = 7). Day-to-day correspondence between IVR and Form-28 was modest, but much stronger for the most recent week assessed than for the prior 3 weeks. Finally, the drinkers reported significantly greater total SDUs and heavy drinking days on the Form-28 than via IVR. The results indicate a need for further refinement of IVR methodology for treatment seeking populations as well as caution when retrospectively assessing drinking over time periods longer than a week among these individuals.
