Comparative Study
A new instrument to measure patient satisfaction with mammography. Validity, reliability, and discriminatory power.
The benefit of mammography depends on repeated use. Therefore, surveying the mammographic quality as judged by the users addresses an important topic. The authors assess the practicality, validity, reliability, and discriminatory power of a new, brief, multidimensional questionnaire for measuring patient satisfaction with mammography. Items measuring discomfort and attitudes toward repeat adherence were included. ⋯ The discomfort dimension contributed substantially to validity and discriminatory power. Patient behavior with time may be monitored with the new questionnaire, thus representing a valuable tool for scientific and practical purposes.
