Development of the cancer therapy satisfaction questionnaire: item generation and content validity testing.

Objectives: This study was undertaken to develop a new questionnaire, the Cancer Therapy Satisfaction Questionnaire (CTSQ), to focus on the issues oncology patients consider when evaluating chemotherapy in terms of expectations and satisfaction.

Methods: Items of the CTSQ were generated through the review of responses from interviews with oncology patients, physicians, and nurses. Analysis of the data was stratified by disease stage, disease type, and country to explore potential differences between these groups.
