The EORTC Quality of Life Group has developed a questionnaire for evaluating Quality of Life in international clinical trials: EORTC QLQ-C30, which is widely used in many countries. The purpose of this study was to assess the psychometric properties of the third version of this questionnaire, EOR-TC QLQ-C30 (version 3.0), when applied to Spanish prostate cancer patients. METHODS: A sample of 137 prostate cancer patients prospectively filled in the questionnaire three times: on the first and last day of the treatment, and in the followup period. Psychometric evaluation of the structure, reliability and validity was made.
