Summary
The electronic Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ(S)) on a Palm Treo 650 is a valid and easy-to-use tool. Patient data collected electronically showed high concordance with the paper version, supporting its use in clinical research.
Area of Science:
- Allergy and Immunology
- Digital Health
- Health Outcomes Research
Background:
- Transitioning from paper-based to electronic health status questionnaires requires validation.
- Adaptations to new media may not guarantee data accuracy.
Purpose of the Study:
- To adapt the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ(S)) for the Palm Treo 650.
- To assess the ease of understanding and accuracy of the electronic RQLQ(S).
- To validate the electronic RQLQ(S) against its paper version.
Main Methods:
- Seventy adults with rhinoconjunctivitis symptoms completed both electronic and paper versions of the RQLQ(S).
- Participants were randomized to complete either version first, followed by the other after a 2-hour break.
- Data were analyzed for concordance and bias between the two versions.
Main Results:
- High concordance was found between the electronic and paper RQLQ(S) overall scores (ICC=0.95) with no significant bias.
- Concordance for individual domains ranged from 0.86 to 0.94, with minor bias in activity and sleep domains.
- Paper completion was faster (4.1 min) than electronic (4.9 min), though 51% of patients preferred the electronic version.
Conclusions:
- The electronic RQLQ(S) on the Palm Treo 650 is user-friendly.
- The strong concordance between electronic and paper versions supports the validity of the electronic RQLQ(S).
- This electronic tool facilitates efficient and reliable data collection in rhinoconjunctivitis research.
