Computer assisted telephone interviewing: effects on interviewers and respondents.

R M Groves, N A Mathiowetz

    Public Opinion Quarterly
    |January 5, 1985
    PubMed
    Summary

    Computer assisted telephone interviewing (CATI) systems showed minimal impact on survey response distributions and rates compared to paper questionnaires. CATI did demonstrate reduced interviewer variance, though interviewers had mixed preferences for system usability.

    Area of Science:

    • Survey methodology
    • Social sciences research methods
    • Data collection techniques

    Background:

    • Traditional paper questionnaires are widely used in surveys.
    • Computer Assisted Telephone Interviewing (CATI) offers potential efficiencies and standardization.
    • Evaluating the impact of CATI on data quality and interviewer behavior is crucial for methodological advancement.

    Purpose of the Study:

    • To compare the effects of CATI versus paper questionnaires on survey response distributions.
    • To assess CATI's influence on interviewer behavior and nonsampling errors.
    • To evaluate differences in response rates between CATI and paper-based surveys.

    Main Methods:

    • A survey experiment was conducted, randomly assigning cases to either a paper questionnaire or a CATI system.

  • Interviewer behavior, response distributions, and nonsampling errors were measured.
  • Response rates for both methods were compared.

    • Main Results:

    • Few significant differences were observed in response distributions between CATI and paper methods.
    • Some evidence suggests reduced interviewer variance in the CATI group.
    • Response rates showed little difference between the two data collection methods.
    • Interviewers noted CATI's ease of questionnaire flow but preferred paper for editing prior answers.

    Conclusions:

    • CATI systems do not substantially alter response distributions or rates compared to paper questionnaires.
    • CATI may offer benefits in reducing interviewer variance.
    • Interviewers perceive distinct usability advantages for both CATI and paper methods, indicating potential trade-offs.
