Content and context in health education: persuading women to perform breast self-examination.

Content in a breast self-examination (BSE) education program was tested according to three motivational approaches with 923 women in Vermont women's clubs. The program was a slide-tape presentation using one of the three approaches and a BSE demonstration followed by a group discussion led by a nurse. A post-test of 374 women 6 months later showed a significant increase in monthly BSE performance from 40 to 71% regardless of motivational approach and an increase in breast cancer knowledge that was somewhat varied by approach, but was significant across all three approaches. Women who did not adopt monthly BSE after the program had an increase in knowledge similar to those who had adopted it. After the program, older women had somewhat less knowledge but performed BSE as often as younger women. Women with a family history of breast cancer were somewhat less likely to perform monthly BSE than other women, and women admitting to inhibitions about BSE were significantly less likely to adopt the practice than other women, yet their monthly BSE also increased as a result of the program. The significant positive change in BSE and knowledge across all groups appeared to be more a result of the supportive women's club context than of variations in program content. Thus, to achieve desired changes in prevention-oriented health behavior, it is suggested that health educators emphasize structuring a favorable context for the presentation of recommended actions such as BSE.

Breast self-examination practices and breast-cancer stage.

To determine the relation between breast self-examination performance and the clinical and pathological stage of breast cancer at first diagnosis, we studied 335 patients with breast cancer. Approximately one fourth of the patients reported that they had been practicing monthly breast self-examination, and half that they had never practiced breast self-examination. More frequent performance of breast self-examination was associated with more favorable clinical stage and fewer axillary-lymph-node metastases on histologic examination. On pathological examination, the age-adjusted maximum tumor diameter of patients practicing monthly breast self-examination was 1.97 +/- 0.22 cm (mean +/- S.E.M.) as compared to 2.47 +/- 0.20 for those performing self-examination less often than monthly and 3.59 +/- 0.15 for patients never performing breast self-examination. These data associating more favorable clinical and pathological stages of breast cancer with more frequent breast self-examination need to be extended by determination of the survival rates of the various self-examination groups.

Audience interest in mass media messages about lung disease in Vermont.

This study pretested audience interest in 25 potential message concepts to be used in a mass media campaign designed to change knowledge, attitudes, and behavior regarding lung disease. A group of 150 respondents reflecting specific target audiences (smokers, older persons, etc.) rated each concept on the basis of a two-sentence description using Haskins' 0--100 scale. Results indicated that older persons were most interested in message concepts suggesting ways to deal with various lung disease symptoms, and smokers showed highest interest in concepts offering positive and straightforward advice on how to quit smoking, rather than concepts that were negative, cute, or satirical in approach. Recommendations based on audience interest were made for the design of future lung disease media campaigns.

Community education programs to promote mammography participation in rural New York State.

BACKGROUND: Rural women are less likely to receive screening mammography at recommended intervals. This study evaluated efforts to promote screening mammography among women in rural communities through community education interventions and low-cost mobile mammography van services. METHODS: Two matched sets of communities were identified in an isolated rural region. One area received community education programs in addition to the mammography van for 2 years; the second area received only the van services. The educational programs were designed using diagnostic research methods; they included recruitment of opinion leaders to organize small group breast screening education sessions, an information campaign using direct mail, and primary health care provider education. RESULTS: A household telephone survey conducted 6 months after completion of these programs indicated that mammography utilization and perceived mammography norms were higher among women in the Program area than among women in the Comparison area. Process data were consistent with these findings. Clinical examination and self-examination behaviors were not influenced by the programs. CONCLUSIONS: This study showed that well-focused educational interventions for rural women can increase utilization of screening mammography when access and cost barriers also are reduced.

Reliability of self-reported breast screening information in a survey of lower income women.

BACKGROUND: Self-reported behavior is widely used to estimate the prevalence of breast cancer screening and to evaluate programs for promoting screening, but detailed studies of reliability have not previously been performed. METHODS: Reliability was assessed by comparing responses to questions about screening behavior from repeat personal interviews of 382 women age 40 and older living in low-income census tracts of two Florida communities. Reliability was assessed using Pearson's correlation (r) and kappa (kappa) coefficients. RESULTS: Estimated reliabilities were kappa = 0.38 for "ever had clinical breast examination," kappa = 0.82 for "ever had mammogram," kappa = 0.65 for "mammogram in past year," r = 0.54 for "date of last mammogram," and r = 0.72 for "number of mammograms." The dates of last mammogram reported at the two interviews agreed within 1 month for 64% of the women, while the dates of last clinical breast examination agreed within 1 month for 50% of the women. Reliability of "ever had mammogram" was significantly related to demographic variables. CONCLUSIONS: Women reliably report ever having mammography, but information about timing and frequency has lower reliability. The results have implications for breast screening research because measurement error affects the precision of estimates and the sample sizes needed to detect program effects.

Long-term responses of higher and lower risk youths to smoking prevention interventions.

BACKGROUND: Adolescents at risk for cigarette smoking are difficult to reach with conventional interventions but have substantial exposure to the mass media. This study is the first to show that smoking prevention messages presented through the mass media can have large and durable effects on higher risk adolescents. METHODS: Students in two communities received media and school interventions beginning in grades 5-7; those in matched comparison communities received school interventions. Media interventions were targeted to higher risk youths. School surveys were conducted before and after the interventions, in grades 4-6 and grades 8-10. Two years after interventions ended, when participants were in grades 10-12, school and telephone surveys were conducted to assess smoking status. Survey participants (n = 2,860) were classified at baseline as having higher or lower risk for becoming a smoker. RESULTS: Smoking prevalence within the higher risk sample was significantly lower for those receiving media-school interventions than for those receiving school interventions only (odds ratio = 0.71). Effects on the lower risk sample were similar in magnitude but marginally significant. CONCLUSIONS: Mass media and school interventions achieved lower smoking rates among higher risk youngsters 2 years following completion of the interventions. This strategy represents a uniquely effective method for communicating with a high-priority group.

Three-year prospective adherence to three breast cancer screening modalities.

BACKGROUND: This study prospectively examined rates of adherence to mammography, clinical breast examination (CBE), and breast self-examination (BSE) in a cohort of women over 3 years to determine whether participation in BSE influenced participation in the other two screening modalities. METHODS: Women ages 51 and older (n = 450) who attended a small group educational session to learn BSE and to hear about CBE and mammography guidelines were assessed annually by telephone for 3 consecutive years to determine their subsequent breast cancer screening behavior. RESULTS: Annual CBE and mammography screening are highly positively associated. Regular performance of BSE has a modest positive association with both CBE and mammography adherence over time. CONCLUSIONS: Women who perform BSE regularly over time may be more likely to adhere to the other breast cancer screening guidelines.

Breast screening by African-American women: insights from a household survey and focus groups.

This study uses quantitative and qualitative information to examine the relationships between predisposing, reinforcing, and enabling factors from a health education planning model and levels of mammography screening, clinical breast exam (CBE), and breast self-exam (BSE) among African-American women. We analyzed data from a random sample household survey of African-American women in a Florida community (n = 281) and three age-homogenous focus groups from the same population. Two thirds of the random sample and all of the focus group participants had less than a high school education and household incomes below $10,000. Even though both samples of women were likely to have a physician they see regularly, most had never had a mammogram and could not accurately describe more than two major techniques for BSE. Knowing guidelines for mammography, CBE, and BSE (predisposing factors), believing their screening behavior mattered to at least some family members (reinforcing factor), seeing a physician for health care and advice, and having been taught BSE in a physician's office (enabling factors) predicted one form of breast screening behavior or another in multivariate logistic regression analyses. In addition, knowing mammography and BSE guidelines and having been taught BSE in a physician's office were significant predictors of breast-screening behavior for both low- and moderate-income women. Focus-group participants unanimously reported a willingness to listen to physician instructions regarding breast screening and to receive a mammogram if their physician recommended one. Both survey and focus group results emphasize the particular importance of physicians in promoting breast screening among African-American women regardless of their income.

The importance of age as a context for understanding African-American women's mammography screening behavior.

INTRODUCTION: Although several studies have explored reasons for lower mammography screening rates among African-American women generally, none has addressed the effect of age as a context for interpreting these reasons. This study examines the association of predisposing, reinforcing, and enabling factors with recent screening mammography behavior for different age groups of African-American women. METHODS: Data are from stratified random sample household surveys of women in two Florida communities (n = 648). Bivariate, log linear, and multivariate logistic regression analyses were performed separately for three different age groups: 40-49, 50-64, and > or = 65. RESULTS: Age was found to be a key context for distinguishing factors associated with having a recent mammogram: Knowledge of screening guidelines and exposure to information about breast screening on radio or television were the most important factors that distinguished the youngest group. Having health insurance and level of education were important factors for the middle group. The most noteworthy differences were found for the oldest group for whom physician recommendation for a mammogram and confidence in being able to get a mammogram were the only significant factors associated with having a recent mammogram. CONCLUSIONS: This study confirms the need to tailor breast screening initiatives to specific age groups of African-American women.

Helping women quit smoking: baseline observations for a community health education project.

INTRODUCTION: Our objectives were (1) to examine the relationship between women's intention of stopping smoking in the next month and a broad range of mediating variables and (2) to assess the implications of these relationships for intervention components of a comprehensive community-wide health education program to help women quit smoking. METHODS: In preparation for the community-wide program to help women quit smoking, baseline data were collected through a random digit dialing telephone survey of 6,324 adult women, 18-64 years of age. RESULTS: At baseline, smoking prevalence, defined as smoking an average of one or more cigarettes per day, was 25.8% and showed clear relationships with age and income, but most strikingly with education, indicating the need for programs for women of childbearing age with low incomes and fewer years of schooling. Among female smokers, knowledge of the health effects of smoking; motivations toward quitting; confidence in controlling weight, or handling stress, anger or boredom; number of strategies named to cope when upset of angry; number of community smoking cessation resources named; perceptions of support for quitting; and perceptions of norms concerning women smoking varied significantly with level of intention to quit smoking in the next month. CONCLUSIONS: These relationships provided support for the broad range of health behavior change strategies proposed for this community-based program to help women quit smoking.
