The purpose of this study was to determine the psychometric properties of two scales, Beliefs about Breast Cancer and Beliefs about Mammography Screening, developed to measure beliefs and attitudes toward breast cancer and mammography screening (MS), and MS practices in African American women (AAW). Most breast cancer and MS questionnaires are designed for and standardized on others and then adapted to AAW. This scale was designed to incorporate the attitudes and beliefs of AAW from an African American cultural perspective. The Transtheoretical Model and the constructs of trust and acculturation provided the theoretical base for the scales. The process of constructing the scales included: (1) reviewing the literature for previous work and gaps; (2) conducting focus groups across three socioeconomic levels; (3) having nine content and survey research experts review the scales; (4) conducting think-aloud focus groups, and (5) distributing the scales to AAW for determination of internal reliability. Factor analysis was computed on each scale to elicit the descriptive sub-factors. Then internal consistency reliability was determined for the total scale and sub-scales. For the Beliefs about Mammography Screening Scale, six factors were extracted that explained 60% of the variance. Alpha for the total scale was .74, with a range from .41 to .87 for sub-scales. Five factors were extracted from the Belief about Breast Cancer Scale that explained 54% of the variance. The total alpha was .69, with alphas for the sub-scales ranging from .30 to .78. These scales can be used in research to evaluate the efficacy of interventions to decrease breast cancer disparity, and in clinical practice to develop individualized plans of care for patients. In addition, findings from logistic regression with stage of change as dependent variable will be discussed. AN: MN030057
