Two questionnaires, the RQLQJ and JRQLQ, effectively assess quality of life in allergic rhinitis patients in Japan. Both show good psychometric properties, with JRQLQ focusing on daily life and RQLQJ on rhinitis health.

Area of Science:

  • Allergy and Immunology
  • Quality of Life Research
  • Clinical Psychology

Background:

  • Allergic rhinitis, including pollinosis, significantly impacts patient quality of life (QOL).
  • A lack of standardized QOL questionnaires in Japan has been a limitation in managing this condition.
  • Two QOL assessment tools are available: the Japanese version of the Rhino-conjunctivitis Quality of Life Questionnaire (RQLQJ) and an original Japanese QOL questionnaire (JRQLQ).

Purpose of the Study:

  • To compare the RQLQJ and JRQLQ for clinical use in Japan.
  • To evaluate the psychometric properties of both QOL questionnaires for allergic rhinitis.
  • To determine the appropriateness of each questionnaire for assessing patient QOL.

Main Methods:

  • A multicenter, cross-sectional study involved 187 adult patients with Japanese cedar pollinosis.

  • Patient scores from the RQLQJ and JRQLQ were compared across overall and comparable domains.
  • Acceptability, construct validity, and reliability of both questionnaires were assessed.

    • Main Results:

    • Both questionnaires demonstrated high correlation in overall and domain-specific scores.
    • Satisfactory psychometric validity was found for both RQLQJ and JRQLQ, confirming their utility.
    • The JRQLQ emphasizes daily life activities and simplicity, while the RQLQJ is more responsive and focuses on rhinitis-specific health.

    Conclusions:

    • Both the RQLQJ and JRQLQ are suitable for assessing QOL in allergic rhinitis patients in Japan.
    • The choice between questionnaires depends on specific research or clinical domain targets.
    • These validated tools improve QOL assessment in Japanese patients with allergic rhinitis.
