Reliability and validity of breast cancer screening belief scales in African American women.

The purpose of this study was to describe the psychometric development of culturally sensitive scales to measure beliefs related to mammography and breast self-examination screening. Health Belief Model constructs of susceptibility, benefits, barriers, and self-efficacy were refined from previously existing instruments to reflect cultural sensitivity. A total of 329 African American women 45 to 64 years of age were included in the sample. Construct validity was tested using confirmatory factor analysis and testing of theoretical hypotheses. Cronbach alpha reliability coefficients ranged from .65 to .90, and test-retest reliability ranged from .40 to .68.

MR imaging of phenylketonuria.

Cranial MR imaging was performed on nine patients (13-27 years old) with classical phenylketonuria in order to define the spectrum of abnormal findings and to determine if these could be related to clinical or biochemical findings. MR abnormalities consistent with demyelination were found in varying degrees in a distribution corresponding to previous histopathologic studies. Specifically, increased signal was seen on T2-weighted sequences, most marked in the periventricular deep cerebral white matter. These changes were more prominent posteriorly, especially about the optic radiations. Comparison with clinical history and MR findings in this small series revealed that patients with adequate dietary control of phenylalanine levels had less severe white matter abnormalities than did patients with poorly controlled phenylalanine intake.
