Some studies of computerized interviews particularly those that deal with personally sensitive topics demonstrate that people have a preference for automated interviews versus live interviews. To ...explore this phenomenon, we administered four open-ended questions after participants were screened for problem drinking by both an automated and a human telephone interviewer. Both interviews administered AUDIT (Alcohol Use Disorders Identification Test) for assessing problem drinking. Individuals were recruited into the study who responded to ads in daily papers. Sixty-two percent of the participants preferred the human interviewer and only 3% among these expressed a concern about confidentiality of the interview. Among the 22% who preferred the automated interview, 32% indicated confidentiality as a reason for their preference.
This study assessed test-retest reliability and criterion validity for an automated version of the Alcohol Use Disorders Identification Test (AUDIT), a screening tool for alcohol-related problems. ...Participants' willingness to use such a system to learn about and change their drinking behavior was also assessed.
Participants were 202 callers recruited through newspaper ads and flyers asking for volunteers concerned about their drinking and willing to help test a new method of screening and referral for alcohol problems. Participants were divided into two groups. The first group of subjects recruited received the Telephone-Linked Communications (TLC)-AUDIT twice, administered a week apart. The second group received the TLC-AUDIT once and a human-administered AUDIT once, also a week apart.
Test-retest reliability was assessed in 102 participants; the intraclass correlation of AUDIT scores between both administrations was .87; kappa for nonproblem versus problem drinking (AUDIT score of 8 or above) was .89. The validity study compared the TLC-AUDIT scores of the next 100 participants to AUDIT questions administered by a human interviewer. The intraclass correlation was .94; kappa was .75. Seventy-five percent of all participants who screened positive for problem drinking agreed they would "talk to a computer again to learn more about your drinking pattern and how to deal with it".
Automated telephone technology can be used to administer the AUDIT instrument with high levels of reliability and validity. This technology could be used to deliver behavioral change interventions.
