Mundt, James C., Michael J. Bohn, Monica King,
Michael T. Hartley: Automating Standard Alcohol Use Assessment Instruments
Via Interactive Voice Response (IVR) Technology. Alcoholism
Clinical and Experimental Research. 26(2): 207-211.
Background Interactive
Voice Response (IVR) technology integrates touch-tone telephones
with computer-automated data processing. IVR offers a convenient,
efficient method for remote collection of self-report data.
Methods Twenty-six
subjects recruited from an outpatient alcohol treatment center completed
IVR and paper/pencil versions of a demographic and drinking history
questionnaire, Stages of Change Readiness and Treatment Eagerness
Scale, Drinker Inventory of Consequences, Obsessive-Compulsive Drinking
Scale, Alcohol Dependence Scale and two numeric rating scales of
craving and desire to drink during the prior week. Administration
of the instruments in both formats was repeated one week later.
The order of administration method was counter-balanced between
subjects and reversed across data collection sessions. Scale and
subscale scores from both methods were correlated within sessions.
Test-retest correlations were also calculated for each method. A
criterion of a = .01 was used to control Type I statistical
error. Study subjects were compensated $40.00 for participation.
Results Intermethod
correlations within each session were significant for all of the
instruments administered. Test-retest correlations for both methods
were also significant, except for the numeric ratings. Scores on
the Alcohol Dependence Scale obtained via IVR were significantly
lower than those collected by paper/pencil. Other differences between
the data collection methods or across the sessions were inconsistent.
The average IVR call length was 34 minutes and 23 seconds. Paper/pencil
forms required an average of 18 minutes and 38 seconds to complete
and an additional 10 minutes and 17 seconds of data entry.
Discussion IVR
technology provides a convenient alternative to collecting self-report
measures of treatment outcomes. Both paper/pencil and IVR assessment
provide highly convergent data and demonstrate good test-retest
reliability. Alcohol Dependence Scale score differences between
methods highlight special considerations for IVR adaptation of existing
paper/pencil instruments. Benefits of IVR include procedural standardization,
automatic data scoring, direct electronic storage, and remote accessibility
from multiple locations.
