Pressing the key pad: trial of a novel approach to health promotion advice.

BACKGROUND: A relatively simple procedure, the Pap test, is effective in detecting early changes in the cervix; however, many at-risk women, even in developed countries, do not have regular Pap tests. METHODS: A randomized controlled trial of an interactive voice response (IVR) cervical screening brief advice involving 17,008 households is described. The IVR system automatically made calls to households and explained the nature of the call; selected one eligible woman aged 18-69 years; determined her screening status; delivered a message appropriate to her screening status; offered additional messages to counter common barriers; offered additional information on cervical screening and cancer; offered additional contact numbers; and offered to arrange for someone to call back. Cervical screening rate data were obtained from the Australian Health Insurance Commission (HIC) for 6 months before and following the intervention. RESULTS: The cervical screening rate was found to have increased by 0.43% in intervention compared to the control postcodes, and the increase was greater for older women at 1.34%. CONCLUSIONS: The overall conclusion was that IVR technology was a feasible means to contact women to deliver brief interventions aimed at increasing cervical screening rates and could economically target at-risk groups. The potential for linking IVR to centralized Pap test Registers to issue Pap test reminders should be explored.

Pilot of a novel cervical screening intervention: interactive voice response.

OBJECTIVE: This paper describes the pilot of an interactive voice response (IVR) cervical screening brief advice interface. METHOD: In September 2000, 5,000 households within Cessnock, New South Wales, were contacted by an IVR system. The system randomly selected eligible women aged 18-69, assessed their cervical screening status and provided a tailored message about cervical screening. A computer-assisted telephone interview (CATI) evaluated intervention acceptability. Participation rates, participant demographics, IVR use by women, and IVR costs were also examined. RESULTS: 549 (12%) women listened to the IVR call and 587 (59%) completed the CATI interview. IVR listeners under-represented younger and older women, and over-represented women who were married, and of Aboriginal descent. The majority of women (98%) found IVR easy to answer and 90% agreed IVR reminders were a good idea. Unscreened and older women used the system more than screened or younger women. CONCLUSIONS: The IVR call was successfully used by a large number of women to obtain information on cervical cancer screening, with higher use by recognised risk groups. IMPLICATIONS: These results suggest that an IVR reminder might be useful to increase cervical screening rates since those most at risk also used IVR the most. The potential for linking IVR to a database to issue reminders in the same manner as Pap Test Register postal reminders needs to be explored.

Generalized Electronic Interviewing System (GEIS): a program and scripting method for conducting interviews in multiple modes.

A program called the Generalized Electronic Interviewing System (GEIS) was developed for conducting interviews, using computer-assisted telephone interview (CATI) and interactive voice response (IVR) modes without the need for a programmed interface. GEIS questionnaires were prepared using a common script syntax in all supported modes. Scripted development allowed for rapid interview development without the need for programming. A GEIS script specified the following: question texts, including variable texts; answer option texts; numeric codes for answers; range check information; logical question-branching information; interview status information; do-loop information; and IVR information, such as key codes and voice messages. GEIS thoroughly checked scripts for logical or syntactical errors. GEIS required SAS Version 8.0, and survey data were accumulated within SAS data sets. An application of GEIS to conduct a survey involving CATI, IVR, and a combined hybrid method is described. The CATI results deviated in the direction expected for sensitive questions, whereas IVR obtained a small sample size, rendering the results unreliable. However, the hybrid method was found to provide more accurate telephone survey data on alcohol consumption than did CATI alone.

Interactive voice response: review of studies 1989-2000.

A systematic review of the use of interactive voice response (IVR) was conducted. IVR is a telephone interviewing technique in which the human speaker is replaced by a high-quality recorded interactive script to which the respondent provides answers by pressing the keys of a touch telephone (touchphone). IVR has numerous advantages, including economy, autonomy, confidentiality, access to certain population groups, improved data quality, standardized interviewing, multilingual interfaces, and detailed longitudinal assessments. Despite this, there have been few applications of IVR. Previous studies have been in the areas of information services, reminder calls, monitoring, assessment, experimentation, interventions, and surveys. Areas that have received little attention have been the systematic evaluation of voice, multilingual interfaces, touchphone prevalence, survey response rates, use by the elderly, and acceptability.

A comparison of four computer-based telephone interviewing methods: getting answers to sensitive questions.

Interactive voice response (IVR) technology presents a new and promising approach by which to collect accurate data on sensitive topics by telephone interviews. In a national survey of 2,880 households of alcohol and drug consumption, we compared computer-assisted telephone interviewing (CATT) and IVR with two hybrid methods that combine IVR with CATI. The principal hypothesis was that the self-report rates of sensitive behaviors would be higher for the hybrid and IVR methods owing to greater perceived confidentiality than with CATI. All the methods obtained similar sample demographic compositions. Response rates did not differ significantly between the CATI and the hybrid methods; however, the response rate with IVR was significantly lower. The hybrid and IVR methods obtained significantly higher self-report consumption rates for alcohol and marijuana and significantly higher hazardous drinking scores, as measured by the Alcohol Use Disorders Identification Test (AUDIT).
