    Summary

    Interviewer-administered surveys using probing algorithms significantly improve the validity and reliability of health-related quality of life (HRQOL) measurements compared to self-administered questionnaires.

    Area of Science:

    • Health Policy
    • Psychometrics
    • Quality of Life Research

    Background:

    • Health-related quality of life (HRQOL) measurement faces challenges in validity assessment and underreporting of dysfunction.
    • The Quality of Well-being scale (QWB) is frequently used for HRQOL data collection, including for the General Health Policy Model.
    • Previous investigations have noted underreporting of dysfunction in health status measurements.

    Purpose of the Study:

    • To compare the validity and reliability of self- versus interviewer-administered modes for the QWB.
    • To evaluate the impact of direct-answer questions versus probing algorithms on QWB measurement.
    • To assess measurement performance using correlations, aggregate frequencies, individual classifications, and actual health states.

    Main Methods:

    Related Experiment Videos

  • Comparison of QWB scores obtained through self-administration versus interviewer administration.
  • Evaluation of short, direct-answer questions against probing algorithms within the interviewer mode.
  • Analysis of measurement properties including sensitivity, specificity, and predictive values for dysfunction and function.

    • Main Results:

    • Extremely high correlations (r > 0.98) were observed between self- and interviewer modes.
    • Interviewer mode demonstrated superior sensitivity (0.86) and predictive value for dysfunction (0.91) compared to self-classification (0.66, 0.73).
    • Specificities and predictive values for function were equivalent (> 0.94) across both modes; interviewer probing reduced false reports of dysfunction.

    Conclusions:

    • Interviewer-administered instruments employing question algorithms are essential for reliable and valid HRQOL measurement.
    • These methods are crucial for evaluating major clinical trials and follow-up studies.
    • Addressing underreporting of dysfunction is key to accurate HRQOL assessment.
