Background
Relapse rates following cognitive behavioral therapy (CBT) for alcohol
dependence are high. Continuing care programs can prolong therapeutic effects but are
underutilized. Thus there is need to explore options having greater accessibility.
Methods
This randomized controlled trial tested the efficacy of a novel, fully
automated continuing care program, Alcohol Therapeutic Interactive Voice Response
(ATIVR). ATIVR enables daily monitoring of alcohol consumption and associated variables,
offers targeted feedback, and facilitates use of coping skills. Upon completing 12 weeks
of group CBT for alcohol dependence, participants were randomly assigned to either four
months of ATIVR (n=81) or usual care (n=77). Drinking behavior was
assessed pre- and post-CBT, then at 2 weeks, 2 months, 4 months, and 12 months
post-randomization.
Results
Drinking days per week increased over time for the control group but not the
intervention group. There were no significant differences between groups on the other
alcohol-related outcome measures. Comparisons on the subset of participants abstinent at
the end of CBT (n=72) showed higher rates of continuous abstinence in the
experimental group. Effect sizes for the other outcome variables were moderate but not
significant in this subgroup.
Conclusions
For continuing care, ATIVR shows some promise as a tool that may help clients
maintain gains achieved during outpatient treatment. However, ATIVR may not be adequate
for clients who have not achieved treatment goals at the time of discharge.
