    A new Nausea Questionnaire offers valid measures for chemotherapy-induced nausea. It provides three key indices (nausea rating index, overall nausea intensity, visual analogue scale) to assess patient experiences effectively.

    Area of Science:

    • Oncology
    • Psychometrics
    • Patient-Reported Outcomes

    Background:

    • Chemotherapy often causes significant nausea, impacting patient quality of life.
    • Existing measures for nausea intensity and quality are insufficient for evaluating anti-nausea treatments.
    • There is a need for reliable tools to quantify the subjective experience of chemotherapy-induced nausea.

    Purpose of the Study:

    • To develop and validate a new questionnaire for measuring nausea in patients undergoing chemotherapy.
    • To establish reliable indices for assessing overall nausea intensity and subjective qualities.
    • To provide a tool for evaluating the effectiveness of anti-nausea interventions.

    Main Methods:

    • Utilized a modified McGill Pain Questionnaire for 25 chemotherapy patients to describe nausea qualities and intensity.

  • Collected overall nausea intensity (ONI) estimates from 17 physicians and 8 nurses for 17 chemotherapy drugs.
  • Correlated questionnaire scores with healthcare professional ONI estimates and compared patient groups receiving different chemotherapy agents.

    • Main Results:

    • Affective and miscellaneous word categories from the questionnaire significantly correlated with physician and nurse ONI estimates.
    • The developed Nausea Questionnaire yielded three valid and intercorrelated indices: Nausea Rating Index (NRI), ONI, and Visual Analogue Scale (VAS) intensity.
    • All three indices demonstrated significant differences between patients receiving cisplatin versus 5-fluorouracil, confirming sensitivity to treatment variations.

    Conclusions:

    • The Nausea Questionnaire provides three valid and reliable indices for assessing the subjective experience of nausea.
    • This tool can aid in the objective evaluation of anti-emetic treatments and clinical trials.
    • The findings support the use of the Nausea Questionnaire in oncology care and research settings.
