BACKGROUND: The purpose of this report is to describe the characteristics of women ages 50 to 80 who do not follow commonly accepted mammography screening guidelines. It provides unique understanding of the robustness of characteristics of underusers across five different U.S. subpopulations. METHODS: The data are from the baseline surveys of the five studies of the NCI Breast Cancer Screening Consortium. Stage of adoption of mammography screening and other characteristics of underusers are presented. Polytomous logistic regression analysis was used to explore multivariable associations with stage of adoption in each study site. RESULTS: The five samples studied by the Consortium range in size from 259 to 4,477 women (n = 11,292). The relationship of the perceptions of the pros and cons of mammography with stage of adoption was strikingly similar across the five samples. Other variables consistently associated with stage were a recent receipt of a breast physical examination and recommendation for mammography by a physician. CONCLUSIONS: The findings suggest a need to encourage regular screening through effective communication from a health care provider. Intervention messages should be designed to increase the pros of mammography, decrease the cons, and highlight these differentially according to the woman's stage of adoption.
Little is published about step-by-step implementation of telephone counseling interventions to promote community-based health activities. This article describes the authors' experience of implementing a church-based telephone mammography counseling intervention with peer counselors representing three principal racial or ethnic groups: African American, Latino, and Anglo (White). Twenty-six women from 12 churches in the Los Angeles area were recruited and trained to deliver the counseling annually over a two-year period to 570 women participants who were recruited from participating churches (n = 15). The counseling sessions were conducted from church-based telephone centers in key geographic locations in our program area. Training and supervision proved challenging: most of the Latino counselors had fewer than seven years of education and spoke only Spanish, while most of the other counselors had at least some college and spoke only English. Culturally specific and small group interactions, role plays, and a more modular approach to training were the most effective ways to enhance counselors' skills. Latina participants' mammography adherence rates were lowest, and their barriers reflected their low socioeconomic status; as Latina counselors shared basic information about mammograms and where to obtain them at little or no cost, the counseling exchanges tended to be nonconflictive and supportive. Black and White participants were generally more knowledgeable and adherent with screening guidelines than Latinas. We found that it was possible to implement this intervention with diverse groups and conclude with lessons learned that may inform others considering such a strategy.
The results of quality control (QC) tests on 70 mammography units in Southern California from 1986 to 1990 are reported. Thirteen facilities, selected because they housed all of the mammography units in three communities involved in a National Institutes of Health research project, had their units tested twice at an interval of 1 year. Fourteen self-selected units were also tested twice at intervals ranging from 1-3 years. Forty-three self-selected units in 31 additional facilities had testing only once. All 70 units underwent measurement of focal spot size or resolution, tube output, half-value layer (HVL), automatic exposure control (AEC) accuracy, relative kVp accuracy, mean glandular dose, and imaging of several test objects. The test results for the units tested once showed no significant differences compared to those tested twice. For the latter, once the units were tested and determined to be acceptable, retesting showed differences only in overall film optical density, dose, and AEC performance.
