Screening mammography behavior after a false positive mammogram.

This pilot study describes women's interpretations of the experience of a false positive mammogram followed by a negative biopsy and the impact of this experience on subsequent participation in screening mammography. A 25-min, open-ended telephone interview was administered in 1992 to 30 women over age 39 who had negative biopsies in 1987 preceded by abnormal mammograms. Almost twice as many women reported getting regular mammograms after the biopsy (60%) as did before 1987 (33%). Most received their next mammogram after the biopsy within the recommended interval (73%), and those getting regular mammograms prior to the biopsy experience were more likely than those who did not have a prior habit of undergoing mammography to continue to get them afterwards. These preliminary findings suggest that a negative breast biopsy after a positive mammogram does not reduce a patient's likelihood of undergoing screening in the future. In fact, it may serve as an impetus for increased compliance with screening recommendations.

The development of an instrument for assessing the quality of life of people with diabetes. Diabetes-39.

OBJECTIVES: The aim of this 2-year research project was to develop an instrument specifically designed to assess the quality of life of people with diabetes. METHODS: The project was divided into two phases. In the first phase, information from a detailed literature review, from existing quality-of-life instruments, and from interviews with health professionals and people with diabetes was used to develop an initial instrument of 92 items considered to address important aspects of patients' lives. This questionnaire was mailed to 1,000 people with diabetes, and data from the 516 respondents were used to select the most important and useful items. Fifty items were excluded, leaving 42 items that constituted the pilot instrument. During phase 2, the pilot instrument was used to assess the quality of life of 427 diabetic patients who completed the revised questionnaire. After analyzing this data, three additional items were dropped. The final instrument consists of 39 items and covers five dimensions of patients' lives: Energy and Mobility, Diabetes Control, Anxiety and Worry, Social Burden, and Sexual Functioning. RESULTS: The results of validity and reliability tests conducted to date testify to the relevance of the 39-item questionnaire (Diabetes-39) as a valid discriminative instrument, one which shows significant correlations with an overall quality-of-life assessment, the pattern of diabetes severity, and comorbidity. Further, the results from Diabetes-39 correlate well with the results from the established generic quality-of-life instrument, the Medical Outcomes Study 36-Item Short-Form Health Survey. CONCLUSIONS: Validation of a quality-of-life instrument, however, is an ongoing process. Further research is required to corroborate these early findings and to ensure that this is an instrument that can capture data of greatest relevance to the diabetic patient and that is responsive to change in quality of life.

Lay health advisors: a strategy for getting the word out about breast cancer.

Transforming natural helpers into lay health advisors (LHAs) is a complex undertaking. Using the North Carolina Breast Cancer Screening Program (NC-BCSP) as a case study, this article describes the steps involved in developing, implementing, and evaluating an LHA intervention, considering factors that make the LHA approach appropriate for the NC-BCSP's population, setting, and health focus. The authors review five phases of implementation (start-up, training, LHA activities, follow-up, resource mobilization) and discuss the NC-BCSP's evaluation strategies and tools in light of difficulties involved in assessing natural helping processes and impact. Program challenges related to resource needs, identification of natural helpers, and LHA monitoring and support also are considered. The authors describe ways in which one large group of older, rural, African American LHAs are helping establish countywide partnerships between health care providers, agencies, and local communities that support and sustain individual changes in health behavior.

Race and mammography use in two North Carolina counties.

OBJECTIVES: This study investigated racial differences in mammography use and their association with physicians' recommendations and other factors. METHODS: The study used 1988 survey data for 948 women 50 years of age and older from the New Hanover Breast Cancer Screening Program. Racial differences in terms of physician recommendation, personal characteristics, health characteristics, and attitudes toward breast cancer and mammography were examined. Factors at least minimally associated with race and use were included in multivariate logistic regression analyses to examine the effect of race while controlling for other factors. RESULTS: In comparison with White women. Black women were half as likely to report ever having had a mammogram (27% vs 52%) and having a mammogram in the past year (17% vs 36%). Black women also significantly less often reported physician recommendation (25% vs 52%). Although Black and White women differed significantly in other characteristics, multivariate logistic regression analyses indicated that physician recommendation accounted for 60% to 75% of the initial racial differences in mammography use. CONCLUSIONS: Understanding physicians' recommendations for breast cancer screening is a critical first step to increasing mammography use in disadvantaged populations.

Rural gonorrhea in the southeastern United States: a neglected epidemic?

Some rural counties in the southeastern United States are experiencing high rates of gonorrhea; however, existing knowledge of epidemiologic patterns of gonorrhea within communities is from urban areas. This paper describes the epidemiology of gonorrhea within a rural county of North Carolina and compares it with the patterns described for large cities. Data include gonorrhea reports from private physicians and the county health department from August 11, 1992, to August 10, 1993, and ethnographic interviews. The rate among males (1,602 cases per 100,000 person-years) was twice that among females. The risk of reinfection within 6 months of an initial infection (12.9%) was high compared with risks in urban settings. Although case numbers did not cluster by geographical area as described for some cities, case rates did. Factors favoring transmission in rural communities include greater poverty and fewer health care resources than in urban settings, the exchange of sex for crack cocaine, and a lack of anonymity that may cause some people to avoid seeking treatment or acknowledging risky sexual behaviors in a clinical setting. Addressing high rural rates will entail improving access to care, taking extra measures to ensure confidentiality, and dispelling the myth that high rates are limited to cities.

Effect of organization-level variables on differential employee participation in 10 federal worksite health promotion programs.

Guided by a conceptual model, the authors used both qualitative data (e.g., individual interviews, focus groups) and quantitative data from an employee survey (N = 3,388) in 10 federal agencies to investigate whether organization context and implementation process affected participation in worksite health promotion and disease prevention (HPDP) activities among demographic subgroups. Overall, employees on average participated in fewer than two agency-supported health-related activities per year (17% in fitness, 40% in health risk assessment activities). Employees participated more where coworkers endorsed such programs. Minority employees and employees in lower level positions were more likely to participate in fitness activities when organizations had a more comprehensive program structure, engaged in more marketing strategies, gave time off to employees to participate, or had on-site facilities. Management support for the program was related to participation by employees who were male, white, and had upper level positions. The data supported the proposed model; also confirmed was two predicted relationships between model constructs, which provided a better understanding of differential participation by employee groups.

The North Carolina Breast Cancer Screening Program: foundations and design of a model for reaching older, minority, rural women.

Breast cancer screening programs do not reach all women at the same rate. Screening mammography use varies according to sociodemographic characteristics; mammography utilization is highest among women in their fifties but then decreases with age. In North Carolina, breast cancer is a particular burden for Black and lower-income women. Black women are more likely to be diagnosed with late stage disease, and their rate of breast cancer mortality is higher than it is for White women even though the incidence in White women is greater. Older, Black, and low-income women are less likely to obtain screening by mammography and clinical breast examination. The Black-White gap is even more pronounced among rural women, in part because they are more likely to be poor. The North Carolina Breast Cancer Screening Program (NC-BCSP) was established to increase the rate of regular mammography screening by an absolute 20% in 3 years among older Black women ages 50 and older in five rural counties in the eastern part of the state. In this paper, we describe the genesis of this comprehensive community intervention model, highlighting the behavioral science constructs, health education principles, and theories of behavioral and organizational change that form its conceptual foundation. NC-BCSP's theoretical foundations include the social ecological perspective, the PRECEDE model of health promotion, the Health Belief Model of individual change, and the "stages of change" transtheoretical model. We also review the experiences and lessons learned from two previous outreach initiatives in North Carolina that provided valuable "lessons" in the development of the NC-BCSP intervention model. In the second half of the paper, we describe the actual NC-BCSP interventions, activities, and evaluation tools, citing specific examples of how the underlying theories are implemented. NC-BCSP's goal goes beyond individual behavior change to raise low mammography screening rates among Black women in rural North Carolina. Its ultimate objective is to create linkages across agencies, and between agencies and communities, that will endure after the research project ends.

Measuring battering: development of the Women's Experience with Battering (WEB) Scale.

Measuring only the physical markers of violence (e.g., slapping, beating) fails to capture the chronic vulnerability and gendered nature of battered women's experiences. Instruments that measure only observable discrete events may mask the continuous nature of battering and the relation between events and experience. Our approach to measuring battering operationalizes the experiences of battered women rather than the abusive behaviors they encounter. This alternative approach emphasizes the meanings battered women attach to the violence and to battering as an enduring presence in their lives. Focus groups with 22 battered women generated qualitative data for developing scale items (Smith, Tessaro, & Earp, 1995) and a known-groups survey with 185 battered and 204 nonbattered women determined the final scale items. Factor analysis of 40 initial items revealed a strong single-factor solution. The resulting 10-item Women's Experiences with Battering (WEB) Scale demonstrated high internal consistency reliability, was significantly correlated with known-group status, exhibited good construct validity, and was not significantly correlated with a measure of social desirability. The WEB Scale provides researchers with a valid and concise measure for studying relations between battering and health or health behavior, as well as evaluating the impact of interventions on battered women or prevalence.

Gynecologists' sex, clinical beliefs, and hysterectomy rates.

This study determined how gynecologists' sex, beliefs, appropriateness ratings, and practice characteristics influence hysterectomy rates in North Carolina. Gynecologists who performed hysterectomies at higher rates were further from training, practiced in areas with fewer gynecologists, and had more patients with abnormal bleeding or cancer. Male gynecologists performed 60% more hysterectomies than female gynecologists, but this may have been because they were further from their training. Appropriateness ratings were affected by gynecologists' attitudes toward surgery, recency of training, and practice case mix, and by patients' expressed desire to avoid surgery, but they did not predict hysterectomy rates. To decrease their chances of undergoing hysterectomy, patients should express their preferences and possibly seek the opinion of more recently trained gynecologists.

Increasing mammography utilization: a controlled study.

BACKGROUND: Despite the effectiveness of breast cancer screening for women older than 50 years of age, only about one third of these women in the United States receive annual mammography. PURPOSE: This study was designed to determine if a community-wide intervention could increase use of mammography screening for breast cancer. Secondary end points were determination of changes in women's knowledge and attitudes toward mammography and physicians' self-reported screening practices. METHODS: We conducted a controlled study from January 1987 through January 1990 in two eastern North Carolina communities--New Hanover County (the experimental community) and Pitt County (the control community). Before development and implementation of the intervention program in New Hanover County and after the program had been in operation for 1 year, 500 women of ages 50-74 years and all primary-care physicians in each community were interviewed by telephone. In these interviews, we determined the use of mammography for breast cancer screening and the knowledge and attitudes about it. We also established the number of screening mammograms performed in 1987 and 1989 in each county and reviewed medical records to determine the percentage of women the physicians had referred for mammograms. RESULTS: The percentage of women who reported receiving a mammogram in the previous year increased from 35% to 55% in the experimental community and from 30% to 40% in the control community (difference of differences, 10%; P = .03 after adjustment for race, education, age, and having a regular doctor; 95% confidence interval, 1%-18%). Increases were greater in New Hanover County regardless of age, race, income, and education. However, the increase was less for Black women than for White women, both overall and in most demographic subgroups. The total number of mammograms performed increased 89% in the experimental community and 45% in the control community. Women's knowledge about mammography changed little, but the intention to get a mammogram increased 30% in New Hanover County, compared with a 17% increase in Pitt County--a statistically significant difference (P < .01). Physician reports and medical record reviews in the two communities showed similar increases in the number of mammograms ordered. CONCLUSIONS: A community-wide effort to increase use of breast cancer screening was successful, but more work must be done to reach the National Cancer Institute's goal of annual mammograms for 80% of women of ages 50-74.

The effect of training staff in office-based smoking cessation counseling.

A role for office staff members in smoking cessation counseling has recently been recognized and encouraged. We studied the impact of physician-staff team training in office-based smoking cessation counseling on staff members in 35 practices in Raleigh, North Carolina. Staff members who attended an educational meeting were compared with two groups: other staff members in their practices who did not attend the meeting and staff in other practices in which no one attended the meeting. Baseline attitudes toward and participation in smoking cessation activities were not significantly different among the three groups. Four months after the training, staff who had personally attended the meeting reported greater involvement in counseling activities than either of the two comparison groups. Attitudes toward involvement in counseling activities did not change significantly over the study period. Training staff members in office-based smoking cessation counseling may be a useful step toward increasing staff participation in these activities.

Factors associated with pediatricians' participation in Medicaid in North Carolina.

OBJECTIVE: To describe the relative importance of factors influencing pediatricians' participation in Medicaid in North Carolina. DESIGN: Questionnaire survey. SETTING AND PARTICIPANTS: Nonacademic primary care pediatricians in direct patient care at least 50% of the time; 332 (85%) of the 389 eligible pediatricians responded. MAIN OUTCOME MEASURES: Proportion of pediatricians who restricted Medicaid patients' access to their practices. The association between restricting access and the following factors was assessed: Medicaid reimbursement, pediatricians' demographic characteristics, knowledge of the Medicaid program, attitudes toward Medicaid patients and the Medicaid program, and beliefs about whether other physicians were available to care for Medicaid patients. RESULTS: Twenty-nine percent of pediatricians restricted Medicaid patients' access to their practices. The proportion of pediatricians restricting access was 62% in cities, 13% in medium-sized towns, and 12% in small towns (P less than .001), but the proportion of pediatricians in cities who restricted access varied from 87% to 22%. Pediatricians who received a higher proportion of their usual fee were less likely to restrict Medicaid patients' access. The relationship between Medicaid payment and restricted access was substantially weakened after controlling for the following factors: (1) the size of the community, (2) pediatricians' attitudes toward Medicaid payment, (3) their perceptions that they were too busy to care for Medicaid patients, and (4) whether there were other resources for the care of Medicaid patients. At comparable levels of payment, rural pediatricians were about six times less likely than urban pediatricians to restrict access. Pediatricians who knew less about Medicaid reimbursement also restricted access more often. Whether or not they restricted access to new Medicaid patients, pediatricians provided acute, preventive, hospital, and emergency care to the Medicaid patients who were already in their practices. CONCLUSIONS: Existing resources for the care of Medicaid patients, pediatricians' economic dependence on Medicaid, and the local norms of practice may be important factors in pediatricians' decision to participate in Medicaid. Increasing reimbursement will have only modest effects on Medicaid participation. Strategies to improve participation should also address pediatricians' knowledge of the Medicaid program and enlist the support of community physicians.

Measuring the use of mammography: two methods compared.

Population studies often estimate mammography use using women's self-reports. In one North Carolina county, we compared self-report surveys with a second method--counting mammograms per population--for 1987 and 1989. Estimates from self-reports (35% in 1987, 55% in 1989) were considerably higher than those from mammogram counts (20% in 1987, 36% in 1989). We then confirmed 66% of self-reports in the past year. Self-reported use is more accurate regarding whether a woman has had a mammogram than when she had it, but self-reports accurately measure change over time.

Mammography and age: are we targeting the wrong women? A community survey of women and physicians.

To determine mammography use among women with a broad range of ages, the authors surveyed women aged 30 to 74 years and physicians practicing primary care in two eastern North Carolina counties. Twenty-five percent of women in their 30s had ever had a mammogram, and 34% intended to have one in the coming year. From 45% to 52% of women in their 40s, 50s, and 60s had ever had a mammogram, and 55% to 57% intended to have one in the next year. Thirty-seven percent of women aged 70 to 74 years had ever had a mammogram, and 40% intended to have one in the following year. Nineteen percent of physicians reported screening nearly all women aged 30 to 39 years, and 14% screened few women aged 50 to 74 years. Younger women were more worried about breast cancer than older women and assessed their risk as higher, attitudes that were generally associated with higher mammography utilization. These community surveys suggest that mammography use may be excessive among younger women; older women continue to be underscreened.

Disease experience and psychosocial adjustment in children with juvenile rheumatoid arthritis: children's versus mothers' reports.

Adjustment in children with juvenile rheumatoid arthritis (JRA) has been evaluated most frequently by parental or teacher reports and with reference to disease severity. In this study, 38 children, ages 7 to 13 with JRA, and their mothers were interviewed. Modest correlations were found between children and mothers in their assessments of children's perceived competence in several domains (i.e., athletic competence, social acceptance, physical attractiveness, and global self-worth) and in their perceptions of how JRA is experienced by children and families. Children's perceptions of the disease experience were significantly correlated with the four measures of perceived competence, even after controlling for disease severity. The results highlight the importance of cross-validating parental reports with children's self-reports, and demonstrate the need to consider variables other than disease severity--in particular how JRA is interpreted by children--in predicting their adjustment.
