Involving minority and underrepresented women in clinical trials: the National Centers of Excellence in Women's Health.

Recent attention to reducing health disparities among population groups has focused on the need to include in clinical studies, especially clinical trials, participants who represent the diversity of the populations to which study results will be applied. While scientists generally applaud the goal of broadening the characteristics of participants in clinical trials, they are faced with multiple challenges as they seek to include historically underrepresented populations in their research. This article examines the historical and sociocultural context of participation by underrepresented groups, especially women and minorities, in clinical trials, identifies major barriers and challenges facing researchers, and suggests strategies for meeting these challenges. The article draws upon the experiences of the investigators affiliated with the National Centers of Excellence of Women's Health (CoEs).

Multidisciplinary Women's health research: the national centers of excellence in women's health.

Contemporary research increasingly needs to consider the value of a multidisciplinary approach in answering critical health questions. The current article outlines the need for multidisciplinary investigations specifically in reference to women's health, and addresses issues related to generating and sustaining interest in such an approach. In addition, the importance of resources and environment for facilitating multidisciplinary research and advocacy efforts for obtaining funding for this approach are discussed. Methodological issues pertinent to the operationalization of multidisciplinary research in women's health are also addressed, and lessons learned from the National Centers of Excellence in initiating multidisciplinary research in women's health are reviewed.

Predicting mammography and breast self-examination in African American women.

Breast cancer mortality is significantly greater in African American women than in their Caucasian counterparts. The purpose of this study was to identify variables associated with the breast cancer screening behaviors of mammography utilization and breast self-examination (BSE) in a convenience sample of low income African American women. A total of 328 African American women, living in a large midwestern metropolitan area, who were at < or = 150% of poverty level, and between the ages of 45 and 64 years were included in this study. Data were collected over a period of 18 months. Predisposing, enabling, and need variables from Anderson's theoretical framework included perceived susceptibility, benefits, barriers, confidence, knowledge, physician recommendation, demographic characteristics, and past experiences, as well as health-care and insurance information. Variables that significantly predicted mammography utilization included perceived barriers, mammography suggested by health-care professionals, recent thoughts about mammography, and a regular medical doctor. Variables that significantly predicted either frequency or proficiency of BSE included susceptibility, benefits, confidence, knowledge, barriers, and a regular physician. Implications for clinical practice include (a) recognizing predictors of screening among low-income African American women; (b) addressing culturally specific barriers, e.g., cancer fatalism, in order to increase compliance with screening; (c) establishing consistency in primary care providers; and (d) increasing confidence and knowledge through education.

Effect of interventions on stage of mammography adoption.

Mammography has been found significantly to impact mortality in women; however, compliance is still problematic. A theoretical model which combined Health Belief Model (HBM) constructs with stage of mammography adoption was used to investigate the effect of an individualized belief and/or informational intervention on mammography compliance. A control group and three intervention groups (belief, information, and belief and information) were used. A probability sample of 405 women ages 40-88 years without a prior history of breast cancer was randomly assigned to groups. Subjects in the intervention group received individually tailored messages to alter beliefs or provider information related to mammography screening. Women in the combined belief/information group were over two times more likely to have been compliant with mammography 1 year postintervention than those in the control. In addition, groups who received the belief intervention had significantly more women that went from a lower to a higher stage of mammography adoption.

Development of a benefits and barriers scale for mammography utilization.

The purpose of this study was to refine scales to measure Health Belief Model concepts of benefits and barriers using the context of mammography screening. Both scales used a summated Likert format with five response options. Items were first subjected to content analysis by national experts. Data were then collected from a random sample of 581 women who were 35 years or over. Retest data were gathered on a subset of women approximately 4-6 weeks later. Construct validity was established using confirmatory factor analysis and exploratory factor analysis with results confirming independence of constructs. Construct validity was also tested by developing hypotheses based on theoretical relationships. Cronbach alpha reliability coefficients for the benefits scale was 0.79 and for the barriers scale was 0.73. Suggestions for further revisions are offered.

Relationship of age to mammography compliance.

Mammography use varies by age, with older women showing decreased use. The purpose of this research was to identify variables that affect screening use within two different age groups of women, those younger than 50 and those 50 and older. Predictor variables were identified using the Health Belief Model and Theory of Reasoned Action and included susceptibility, seriousness, benefits, barriers, health motivation, control, social influence, and experiential/demographic variables. A probability sample of 581 women aged 35 and older was included for analyses. Two measures of mammography compliance were tested: compliance with American Cancer Society (ACS) guidelines for the 5 years before the study and compliance with the ACS guidelines for the year before the study. An in-home interview was conducted by graduate research assistants. Compliance rates were significantly lower for women 50 and older than they were for younger women for both the 5-year compliance and the single year of compliance. Barriers were more significant for older women. Having a mammography suggested by a health care professional was most important in the older group, indicating that less weight may be given to personal decision making by this population. Higher socioeconomic status was significant with older but not younger women. For older women, interventions need to be directed toward both the physician and the individual woman. Programs that provide knowledge and address cost issues may be the most important primary components for younger women.

Effects of a procedural/belief intervention on breast self-examination performance.

The purpose of this study was to test the effect of a theoretically based nurse-delivered intervention on BSE behavior. A 2 x 2 prospective, randomized, factorial design yielded four groups: control, belief intervention, procedural intervention, and procedural/belief intervention. A total of 301 women were randomly selected from a target population. One year following intervention, significant differences in self-reported proficiency, observer-rated proficiency, and sensitivity (lump detection) were found between the Procedural and Control Group and the Procedural/Belief and Control Group. Significant increases were found on observer-rated proficiency and sensitivity for the Procedural/Belief Group when compared to the Belief Group. In addition, a significant increase was found in the Procedural/Belief Group on nodule detection, when compared to the Procedural Group alone.

The role of breast self-examination in breast cancer screening.

The efficacy of breast self-examination (BSE) behavior cannot be adequately evaluated until BSE proficiency is considered. Previous research supports the role of attitudinal and teaching interventions in increasing skills and frequency for BSE behavior, but more research using age-appropriate women and adequate outcome measures is needed. A preliminary analysis of data from 301 randomly selected women who were followed for 1 year after an initial teaching and/or attitudinal intervention is reported. Significant differences were obtained for attitudes toward breast cancer screening between scores before and after intervention using paired t test. Significant changes in proficiency and frequency also occurred after intervention, as well as percentage increases in nine individual BSE steps. Return demonstration scores and nodule detection are reported. Perceived barriers and confidence were significantly related to both frequency and proficiency 1 year postintervention using regression analysis. Knowledge was related to proficiency measures. Preliminary data suggest that BSE practice can be significantly improved through individually tailored attitudinal and teaching interventions.

Breast self-examination in women 65 and older.

Studies of breast self-examination (BSE) in older women have revealed deficiencies in both frequency and proficiency of practice. Current data from an ongoing study indicate that practice is sufficiently poor as to make the detection of lumps difficult. Interventions to increase frequency and proficiency, however, have been encouraging. Several studies are reporting significant improvement in practice following specific strategies. Barriers such as forgetting and embarrassment need to be addressed when attempting to increase frequency and proficiency. The efficiency of BSE cannot be adequately addressed until women are trained at a proficient level.

Public values and beliefs toward nursing as a career.

The purpose of this study was to compare the perceptions of "ideal career" and "nursing as a career." The goal was to provide information for development of innovative recruitment strategies. The sample of 1,116 included college freshmen, students in grades 6 through 12, parents, school nurses, teachers, and counselors. Data were analyzed by t test and analysis of variance to determine differences in attitudes between "ideal career" and "nursing as a career." Similar perceptions for both were opportunities for employment, application of intellectual abilities, caring for people, and an opportunity for academic and scholastic achievement. An "ideal career" was seen as more financially rewarding, more respected, and more powerful than nursing, and as providing more opportunities for leadership, for making decisions, for obtaining and applying knowledge, and for working in a safe environment. Recommendations include strategies to improve recruitment and retention of nurses.
