EORTC radiation proctitis-specific quality of life module - pretesting in four European countries.
OBJECTIVE
Radiation proctitis is a side effect which can occur after pelvic radiation therapy. Currently available questionnaires do not comprehensively assess the range of problems, nor impact on quality of life associated with proctitis. This article reports on the cultural testing phase of an EORTC module (QLQ-PRT21) developed to assess radiation proctitis specific issues and designed to be used in conjunction with the EORTC core quality of life questionnaire (QLQ-C30).


METHODS
The previously developed 21-item module, pre-tested in Australia, was translated into Norwegian, German, French and Italian. Patients completed the EORTC QLQ-C30 and module questionnaires towards the end of their radical pelvic radiation treatment to target acute side effects. Patients experiencing chronic proctitis were also surveyed. Patients also participated in structured interviews to determine issues of comprehensibility, coverage and relevance. Results were compared with Australian data.


RESULTS
Questionnaires were completed by 64 European patients. The module was found to be relevant and culturally acceptable to participants. Feedback has led to minor translation modifications and the inclusion of two additional questions.


CONCLUSIONS
This module is ready for Phase IV testing which will consist of large scale field testing with the aim to perform psychometric analysis and finalize a module that will be suitable in the assessment of radiation induced proctitis.
