The aim of this study is to validate the EORTC PATSAT-C33 and EORTC OUT-PATSAT7 questionnaires scale structure in a large international field study.

Patient satisfaction is now recognized as an important indicator of care quality. Measures of patient satisfaction with care can facilitate monitoring initiatives for care improvement over time. The EORTC Quality of Life Group has cross-culturally validated a stand-alone in-patient satisfaction with cancer care questionnaire, the IN-PATSAT32. Advances in cancer care delivery required further development of this questionnaire to assess patients' perceived quality of the care received in outpatient cancer care settings. Phase I to III of this process have been completed, resulting in the EORTC PATSAT-C33 satisfaction with cancer care core questionnaire to assess cancer care delivery as a whole and the complementary EORTC OUT-PATSAT7, a questionnaire for the specific outpatient care settings. These questionnaires concern all patients treated for their cancer, in the assessed service, regardless of the stage and type of cancer.

Inclusion Criteria:

Patients regardless of cancer site or stage of disease (i.e. local, loco-regional, metastatic, in remission) will be invited to participate if they meet the following criteria:

1. Diagnosis of cancer confirmed histologically.

2. Patients are 18 years or older (to be adapted for compliance with each country regulation).

3. Patients are willing to express their non-opposition to participate in the study.

4. Patients are able to read and understand the language of questionnaires.

5. Patients have the cognitive ability to complete the questionnaires.

6. Patients have had a sufficient experience of the cancer treatment setting :

   a. For outpatients consulting in a chemotherapy day clinic/consultation for oral treatment, ambulatory radiotherapy or consultation for follow-up surveillance to check for signs of recurrence : i) between 3 to 6 cycles of chemotherapy or at least 2 cycles of other cancer treatment (e.g., biological oral therapy) or ii) between 2 to 6 weeks of radiotherapy or iii) within the 3rd to 24th month post-cancer treatment. b. For inpatients consulting on an oncology or a surgery ward at least 3 days of hospital stay

Exclusion Criteria:

Patients will be excluded if they are :

1. Participating in another patient-reported outcome investigation that may interfere with this study.
2. Experiencing any psychiatric condition or major cognitive impairment that may hamper completion of self-reported questionnaires.
