Abstract
Despite its considerable promise as a screening tool, mammography has thus far not been as widely used as seems warranted. One conceptualization of patient-related factors or motivation useful in previous research on use of services is the Health Belief Model, which postulates that health behavior can be predicted by people's perceptions of the seriousness of the disease, their susceptibility to the disease, and their perceptions of the benefits of and barriers to the health behavior. Yet no psychometrically sound measure of these variables as related to mammography was found in a search of the literature. This study reports the construction and preliminary validation of such an instrument. Factor analysis, moderate or zero correlation of the subscales, and a higher mean score on the Barriers subscale for women referred for mammography as compared to those actually presenting for mammography support the validity of the questionnaire. Although reliability coefficients for Benefits were low, those for Susceptibility and Barriers were adequate. The questionnaire appears to be a promising measure awaiting further validation.
