The purpose of this research was to revise scales measuring perceived susceptibility to breast cancer and perceived benefits and barriers to mammography utilization. A total of 618 women age 50 and over who were enrolled in a large intervention study participated in data collection. Scales were revised beginning with focus group input. Analyses included internal consistency reliability, test-retest reliability, factor analysis, confirmatory analysis, and known groups techniques to test construct validity. Internal consistency ranged from .75 to .88, and test reliabilities from .59 to .72. Construct validity was confirmed with exploratory and confirmatory factor analyses, as well as known group techniques. Overall these scales represent an improvement in those previously reported.
