Acknowledgements This study has received f30 support of a grant from the Health Department of the Gobierno de Navarra. Sociodemographic and clinical data were taken from the clinical records.

The comparisons between the different measurements were satisfactory as they had clinical significance. These instruments can also be used in clinical practice. Interscale correlations were calculated to study discriminant validity Two-tail analysis. Support Care Cancer; 7: This study has received the support of esaol grant from the Health Department ertc the Gobierno de Navarra.

Levels of compliance were high, with little missing data, indicating the instrument was well accepted. Multitrait scaling analysis Esoaol items exceeded the 0. Se han dado pocas excepciones, principalmente en la escala CF. We compared subgroups based on KPS levels: Responsiveness to change There was a significant worsening of the condition between the first eoortc the second measurements in five areas PF, PA, CO, DI, FAa significant improvement between the second and third measurements, with no significant differences between the first and third questionnaires.

Patients completed the QLQ-C30 version 3. Psychometric evaluation of the structure, reliability and validity was made. There was a significant worsening in CF and SF between the first and second measurements, and in GQL between the second and third measurements. Multitrait scaling analysis showed that most item-scale correlation coefficients met the standards of convergent and discriminant validity. In the validation study of version 3.

This QL group has created a combined assessment system composed of a generic core questionnaire, EORTC QLQ-C30, which evaluates issues common to different cancer sites and treatments, and a range of supplementary modules designed to assess specific issues, according to type of treatment or disease site, or to dimensions like fatigue. Data collection procedures Patients completed the QLQ-C30 on the first and last day of radiotherapy, and one eorrc and a half after the end of this particular treatment.

A sample of prostate cancer patients wlq filled in the questionnaire three times: Most scales had low to moderate correlations with the other scales. This sample consisted of patients with localized disease T1-T3 N0 M0 who started radiotherapy with radical intention combined or not with hormotherapy at espakl Radiotherapeutic Oncology Department of the Hospital of Navarre.

New studies with other tumors could have a confirmatory value. Group comparison analyses showed better QL in patients with higher Performance Status.

Known group comparison analysis was performed by means of the Mann-Whitney U tests. Cronbach’s coefficients of the scales were above 0. Most scales fulfilled the reliability criteria, except CF and NV.

The highest correlations were between FA and PF – 0. Group comparison analyses were satisfactory, as they were in line with the clinical data: One of the major tasks of this group is the development of questionnaires for the assessment of QL in clinical trials. Multitrait scaling analyses confirmed the psychometric structure of the questionnaire, and c03 in line with previous studies A consecutive sample of prostate cancer patients was included.

There was also a significant improvement between the second and third measurements, and between the first and the third in SL.

Evaluation of chemotherapeutic agents; ; Colombia University, New York, Few errors appeared, and they were mainly esspaol to the cognitive functioning scale, as in our previous validation and c3 the Zhao and Kanda 16 studies.

Patients’ characteristics and compliance patients from a total of that were addressed filled in the first questionnaire, did the second one and answered the third one.


Few exceptions appeared mainly in CF. The results are in line with previous studies.

Interscale correlation coefficients were somewhat higher in the second measurement. These results showed the QLQ-C30 is highly sensitivity to changes. The structure of this questionnaire is presented in Table I. The standard deviation of NV in the two measurements has been low, which may have affected their Alpha coefficient. Validation study for spanish prostate cancer patients. Internal consistence reliability estimates of the QLQ-C30 scales were above the 0.

These studies are quite useful for professionals as, among other reasons, they offer an estimate of the QL values that could be expected in each country for different groups of patients, and also, because they explore if the QLQ-C30 has a good psychometric functioning when used with specific disease sites and stages.

CF had eepaol shown low reliability scores in the validation studies we carried out with version 1. Item discriminant validity was successful in all analyses except in item eorrtc higher correlation with SF than with its own scaleitem 10 higher correlation with Eortx in the first measurement, and in the second assessment, item 20 higher correlations with EF and SF. Results Patients’ characteristics and compliance patients from a total of that were addressed filled in the first questionnaire, did the second one and answered the third one.

These three analyses were performed at the first and second assessments.
