Measuring mammography and breast cancer beliefs in African American women.

Although intervention trials have demonstrated significant improvement in mammography adherence for African American women, many of the current measurement tools used in these interventions have not been assessed for validity and reliability in ethnic minorities. This study assessed the validity and reliability of Health Belief Model (HBM) variables that are often the target of mammography interventions. Scale validity and reliability was assessed for HBM scales in a sample of 344 low-income African American women. Validity was supported through exploratory factor analysis and theoretical prediction of relationships. Internal consistency reliability was .73 or above for all scales.
