Abstract
Given the seriousness and prevalence of cancer, the lack of a standardized and validated measure of cancer attitudes represents a major gap in psychosocial oncologic research. The article describes the development and validation of the Cancer Attitude Inventory (CAI), a 41-item self-report questionnaire designed to fill this void. The author presents evidence for the reliability, validily, and factor structure of the instrument and offers suggestions for using the instrument in future applied and basic research programs.
