The Life History Interview Method: Applications to Intervention Development

There is an urgent need to develop and test health promotion strategies that both address health disparities and elucidate the full impact of social, cultural, economic, institutional, and political elements on people's lives. Qualitative research methods, such as life history interviewing, are well suited to exploring these factors. Qualitative methods are also helpful for preparing field staff to implement a social contextual approach to health pro-motion. This article reports results and application of findings of life history interviews conducted as part of intervention planning for the Harvard Cancer Prevention Program Project, “Cancer Prevention in Working-Class, Multi-Ethnic Populations.” The salient themes that emerged from interviews with a multi-ethnic, purposive sample are centered on six construct domains: immigration and social status, social support, stress, food, physical activity, and occupational health. Insights gained from thematic analysis of the interviews were integrated throughout intervention and materials development processes.

Access and Attitudinal Factors Related to Breast and Cervical Cancer Rescreening: Why are Latinas Still Underscreened?

To identify access, attitudes, and health practices of Latina women undergoing regular mammography and Pap smear screening, 977 Latinas aged 40 to 74, residing in four California cities, answered a telephone interview. Forty-one percent of women had regular mammography, and 73% had regular Pap smear screening. Cancer screening maintenance was associated with having health insurance, a regular place of care, and fewer fatalistic attitudes about cancer. Regular mammography and Pap smear screening were also associated with ever being married, attending church, and having taken hormone replacement therapy. Being older than 50, residing in the United States a long time, and having had a hysterectomy predicted mammography maintenance. Pap smear screening maintenance was negatively associated with poverty, old age, and negative attitudes toward physicians. There are structural and attitudinal barriers to regular cancer screening among Latinas. Interventions that increase access to care and address women's attitudes about cancer are needed.

Randomized controlled trial of Nuevo Amanecer: a peer-delivered stress management intervention for Spanish-speaking Latinas with breast cancer

BACKGROUND

Latinas with breast cancer suffer symptom and psychosocial health disparities. Effective interventions have not been developed for or tested in this population.

PURPOSE

We describe community-based participatory research methods used to develop and implement the Nuevo Amanecer program, a culturally tailored, peer-delivered cognitive-behavioral stress management intervention for low-income Spanish-speaking Latinas with breast cancer, and unique considerations in implementing a randomized controlled trial to test the program in community settings.

METHODS

We applied an implementation science framework to delineate the methodological phases used to develop and implement the Nuevo Amanecer program and trial, emphasizing community engagement processes.

RESULTS

In phase 1, we established project infrastructure: academic and community co-principal investigators, community partners, community advisory board, steering committee, and funding. In phase 2, we identified three program inputs: formative research, a community best-practices model, and an evidence-based intervention tested in non-Latinas. In phase 3, we created the new program by integrating and adapting intervention components from the three sources, making adaptations to accommodate low literacy, Spanish language, cultural factors, community context, and population needs. In phase 4, we built community capacity for the program and trial by training field staff (recruiters and interventionists embedded in community sites), compensating field staff, and creating a system for identifying potential participants. In phase 5, we implemented and monitored the program and trial. Engaging community partners in all phases has resulted in a new, culturally tailored program that is suitable for newly diagnosed Latinas with breast cancer and a trial that is acceptable and supported by community and clinical partners. Lessons learned Engagement of community-based organizations and cancer survivors as research partners and hiring recruiters and interventionists from the community were critical to successful implementation in community settings. Having culturally and linguistically competent research staff with excellent interpersonal skills facilitated implementation. Facilitating and maintaining excellent communication among community partners was imperative to troubleshoot implementation issues. Randomization was challenging due to community concerns about assigning women to a control group. Patient privacy regulations and the need for extensive outreach to establish relationships between community partners and clinical sites hampered initial recruitment.

LIMITATIONS

These were resource-intensive processes to develop and implement the program that need to be compared to less-intensive alternatives.

CONCLUSION

Engaging community members in design and implementation of community-based programs and trials enhances cultural appropriateness and congruence with the community context. If the randomized trial demonstrates that the intervention is effective, it will fill a gap in evidence-based programs to address ethnic disparities in quality of life among Spanish-speaking Latinas with breast cancer.

Outcome effectiveness of the lay health advisor model among Latinos in the United States: an examination by role

The objective of this study was to examine lay health advisor (LHA) programs designed to promote health among US Latinos and the extent to which educator-only versus educator-plus-bridge programs differed in designs and outcomes achieved. Two independent coders reviewed 128 published articles on LHAs yielding information at two levels: (i) study design and participant and LHA characteristics from 61 studies that broadly compared educator-only versus educator-plus-bridge programs and (ii) implementation features and outcomes from 17 randomized controlled trials or quasi-experimental studies with outcome data. LHA programs have been widely used with Latinos in certain US regions; our findings indicate that LHAs are effective intervention agents. We identified differences between educator-only and educator-plus-bridge LHA programs, although the small number of educator-plus-bridge programs with outcome data limited comparisons. Major gaps remain in research targeting Latino subgroups other than Mexican immigrants/Mexican Americans. Sufficient research has evaluated LHA programs among Latinos on their ability to achieve health behavior and/or health status changes. In the future, more of a focus on organizational and policy changes is warranted. Questions remain about diversity in LHAs' characteristics and roles, which influence not only outcomes but also program sustainability and dissemination.

The role of lay health advisors in cardiovascular risk reduction: a review

Interventions are needed to reduce the negative impact of cardiovascular disease. The combination of health risks for disease, disability, and mortality, particularly among underserved populations, might be best addressed with programs designed to enhance awareness and development of resources within a context of community support. The objectives of this review were to: (1) provide a comprehensive review and evaluation of the roles, evaluation, and effectiveness of LHA in community-based programs with an emphasis on cardiovascular risk reduction; and (2) provide recommendations for future research involving LHA in such programs. Computer and manual searches were conducted of articles in the English-language literature from 1980 to 2007. Twenty articles were evaluated, which emphasized the role of the LHA in cardiovascular risk reduction. A review of research literature provides a starting point for determining salient approaches for intervention and evaluation, issues related to program implementation and sustainability, and strengths and limitations of existing approaches.

Lay health advisor interventions among Hispanics/Latinos: a qualitative systematic review

BACKGROUND

With an expanding Hispanic/Latino community in the United States, practitioners and researchers working to promote health and prevent disease have relied on lay health advisor (LHA) models to address a variety of health issues. The primary goal of this systematic review was to explore how LHA approaches have been used and evaluated within Hispanic/Latino communities in the U.S.

METHODS

Ten literature databases were searched from their inception through July 2006, using keywords associated with LHA approaches. This review consisted of human studies that included adult Hispanics or Latinos of either gender, were conducted in the U.S., were published in English-language peer-reviewed journals, and contained enough abstractable information. Data abstraction was completed independently by three data abstractors using a standardized abstraction form that collected intervention characteristics and study results.

RESULTS

A total of 172 studies were identified and 37 met the inclusion criteria. Of these, 28 included female LHAs exclusively and five included a small number of male as well as female LHAs. Training for LHAs ranged from 6 to 160 hours. Primary roles of LHAs included: supporting participant recruitment and data collection, serving as health advisors and referral sources, distributing materials, being role models, and advocating on behalf of community members. Fourteen studies found evidence of effectiveness.

CONCLUSIONS

Given the long history of using LHAs as an approach to health promotion and disease prevention and the current emphasis of LHA approaches as a potential solution to health disparities in general, and among Hispanics/Latinos in particular, few rigorous studies have been published that document the effectiveness of LHAs on a variety of public health concerns. A stronger empirical evidence base is clearly needed.

Hispanic women's preferences for breast health information: subjective cultural influences on source, message, and channel

The purpose of this study was to investigate the influence of 3 subjective cultural variables--self-construals (independence and interdependence), ethnic identity (bicultural, assimilation, traditional, and marginal), and cultural health attributions (equity and behavioral-environmental attributions)--on source, message, and channel preferences for receiving breast health information by Hispanic women age 35 or older. Subjective cultural variables collectively accounted for 2% to 28% of the variance in communication preferences. In addition, several associations were discovered: (a) having an interdependent self-construal was associated positively with preferences for significant other as a source, family sources, fear messages, media channels, and face-to-face channels; (b) having a bicultural identity was associated positively with preferences for family sources and media channels, but negatively with a desire for no information; and (c) having a marginal identity and equity attributions were associated positively with preferences for fear messages and a desire for no information, but negatively with preferences for expert sources. These findings are discussed in the context of tailoring breast health information to Hispanic women using computer technology and entertainment-education.

Ethnic differences in decisional balance and stages of mammography adoption

Behavioral theories developed through research with mainstream, English-speaking populations have been applied to ethnically diverse and underserved communities in the effort to eliminate disparities in early breast cancer detection. This study tests the validity of the transtheoretical model (TTM) decisional balance measure and the application of the TTM stages of change in a multiethnic, multilingual sample. A random sample of 1,463 Filipino, Latino, African American, Chinese, and White women aged 40 to 74 completed a phone survey of mammography beliefs and practices. Consistent with the TTM and independent of ethnicity, decisional balance was associated with mammography stage in all five ethnic groups when controlling for socioeconomic and other factors. In addition, having private insurance and a regular physician and being a long-time resident in the United States were positively associated with mammography maintenance. The application of the TTM for mammography is supported in a multiethnic and multilingual sample.

Cervical cancer educational pamphlets: Do they miss the mark for Mexican immigrant women's needs?

The rate of invasive cervical cancer in US Hispanic women is nearly doubled that of non-Hispanics. Using in-depth interviews and content/grade level analysis of educational materials, this study explores the relevance of cervical cancer education materials to the needs of Mexican immigrant women. It also addresses health literacy issues that create barriers to learning. Findings show aspects of language, content, reading level, structure, and visual images in 22 cervical cancer pamphlets from 11 health care sites in a Midwest city were not relevant to the learning needs or health literacy levels of local Mexican immigrant women. Further research is recommended to establish an evidence base regarding optimal presentation of key elements of the cervical cancer educational message for Mexican immigrant women.

Depressive symptoms among women with an abnormal mammogram

An abnormal mammography finding constitutes a stressful event that may increase vulnerability by developing or intensifying pre-existing psychological morbidity. We evaluated depressive symptoms using the Composite International Diagnostic Interview among women of four ethnic groups who had an abnormal mammography result controlling for the effect of demographic, psychosocial and medical factors on recent onset of depressive symptoms. Telephone surveys were conducted among women aged 40-80 years recruited from four clinical sites in the San Francisco Bay Area after receiving a screening mammography result that was classified as abnormal but probably benign, suspicious or highly suspicious, or indeterminate using standard criteria. Among the 910 women who completed the interview, mean age was 56 (S.D.=10), 42% were White, 19% Latina, 25% African American, and 14% Asian. Prevalence of lifetime depressive symptoms was 44%, and 11% of women had symptoms in the previous month. Multivariate logistic regression models showed that Asian ethnicity, annual income >$10 000 and weekly attendance at religious services were significantly associated with decreased depressive symptoms. Having an indeterminate result on mammography and being on disability were significantly associated with more depressive symptoms. Reporting a first episode of depression more than a year before the interview was associated with significant increase in depressive symptoms in the month prior to the interview regardless of mammography result. Women with an indeterminate interpretation on mammography were at greater risk of depressive episode in the month prior to the interview compared to women with probably benign results (odds ratio=2.41; 95% CI=1.09-5.31) or with a suspicious finding. Clinicians need to consider depression as a possible consequence after an abnormal mammography result.

Breast cancer knowledge assessment in female Chinese immigrants in New York

The purpose of this study was to examine the relationships between acculturation level and perceptions of health access, Chinese health beliefs, Chinese health practices, and knowledge of breast cancer risk. This descriptive, correlational cross-sectional study used a survey approach. The sample included 135 Chinese women from the New York City metropolitan area. Data were analyzed using correlational techniques and polytomous regression. There were no significant relationships between acculturation and health access, Chinese health beliefs, Chinese health practices, and breast cancer risk knowledge. Only "years of education," "marital status," and "household income" significantly predicted breast cancer risk knowledge level. The data indicate that women with a better knowledge of breast cancer risk are twice as likely to have higher income and have more education. The most knowledgeable women are less likely to be married and less likely to have partners compared to least knowledgeable group. Providers need to promote health knowledge and provide information about as well as access to preventive health practices to the immigrant population, given that acculturation to the new dominant society is inevitable.

Sociocultural characteristics and responses to cancer education materials among African American women

Culture has been linked to cancer-related beliefs and practices. The purpose of the present study was to examine the effects of culture on responses to cancer education materials. Religiosity, collectivism, racial pride, and time orientation were measured among 1,227 African American women. Analyses tested the hypothesis that women scoring higher and lower on each construct would differ in their liking, attention, attitude change, recall, and perceived relevance of tailored materials that did or did not frame cancer issues in a cultural context. Responses to culturally tailored materials were no different than responses to other materials, regardless of women's cultural characteristics. However, for all types of materials, women scoring high on religiosity or racial pride paid more attention to materials, liked them more, and found them more personally relevant than women low on these constructs (all ps<.005). Women scoring high on present time orientation paid less attention to materials than women low on this construct (P<.01). In this population of women, cultural characteristics appear to moderate responses to tailored health education materials.

The Role of Culture in Health Communication

This paper examines the role of culture as a factor in enhancing the effectiveness of health communication. We describe culture and how it may be applied in audience segmentation and introduce a model of health communication planning--McGuire's communication/persuasion model--as a framework for considering the ways in which culture may influence health communication effectiveness. For three components of the model (source, message, and channel factors), the paper reviews how each affects communication and persuasion, and how each may be affected by culture. We conclude with recommendations for future research on culture and health communication.

Patient and Clinical Site Factors Associated With Rescreening Behavior Among Older Multiethnic, Low-Income Women

PURPOSE

Our goal was to identify factors predictive of mammography rescreening within 18 months of baseline screening in multiethnic, low-income older women.

DESIGN AND METHODS

We interviewed a cross-sectional survey of staff of 102 randomly selected clinics that provided screening and diagnostic services. We also surveyed a random sample of 391 older women served by these clinics to retrospectively assess their experiences of the screening process.

RESULTS

We found that 59% of the sample returned for a repeat mammogram. Education level and the belief it is important to get an annual mammogram were significant patient-level predictors of rescreening. Offering pap smears and using hands-on demonstrations with breast models were significant clinic-level variables predictive of rescreening. Of note, among the variables that did not prove significant in the final model were those reflecting ethnicity and income.

IMPLICATIONS

Individual and health-care-delivery-system factors play important roles in the obtaining of regular mammograms by low-income women. These findings highlight the importance of both factors in improving rescreening rates among older women.

Association between CBE, FOBT, and Pap smear adherence and mammography adherence among older low-income women

BACKGROUND

Adherence to regular and timely mammography screening, especially in older low-income women, continues to fall below objectives. The primary aim of this study was to examine whether engaging in other cancer screenings was associated with mammography adherence for older women.

METHODS

Women, ages 52 and over, without a self-reported history of breast cancer (N = 862) were selected from a larger sample of women residing in Washington, DC, census tracts with >/=30% of households below 200% of the federal poverty threshold. A computer-assisted telephone survey was used to collect data on health care system factors, demographics, cultural beliefs, clinical breast exam (CBE), Pap smear, fecal occult blood testing (FOBT), and mammography. Adherence was defined as receipt of the last two screening tests within recommended intervals for age.

RESULTS

After controlling for other variables, adherence to CBE (OR = 4.15; 95% CI, 2.55-6.73) and Pap smear (OR = 1.82; 95% CI, 1.07-3.12) were highly predictive of mammography adherence. Adherence to FOBT (OR = 1.66; 95% CI, 0.97-2.84) was marginally predictive.

CONCLUSIONS

Results of this study indicate that nonadherence to other cancer screenings can help identify women in need of additional interventions to improve mammography adherence.

Hispanic women's experience with "el cambio de vida"

PURPOSE

To examine the factors that influence Hispanic women's decisions to initiate or not initiate hormone replacement therapy (HRT) during menopause to manage symptoms or to prevent longer-term conditions.

DATA SOURCES

A descriptive study of 51 Hispanic women who completed the Spanish version of the Menopausal Decision-Making Questionnaire (S-MDMQ) to describe their experience with and perceptions about menopause.

CONCLUSIONS

Most of the low-income Hispanic women in this study would elect not to take HRT; however, they do use exercise, diet, vitamins, and other self-care activities to manage symptoms of menopause. Hispanic women were eager to discuss how to manage their health care during perimenopause and menopause with one another and their health care providers.

IMPLICATIONS FOR PRACTICE

Nurse practitioners need to understand factors that might influence Hispanic women's decisions regarding management of menopausal symptoms, including the use of HRT, and to be able to assist women in making an individualized personal treatment choice that is culturally acceptable.

Achieving cultural appropriateness in health promotion programs: targeted and tailored approaches

It is a truism of health education that programs and interventions will be more effective when they are culturally appropriate for the populations they serve. In practice, however, the strategies used to achieve cultural appropriateness vary widely. This article briefly describes five strategies commonly used to target programs to culturally defined groups. It then explains how a sixth approach, cultural tailoring, might extend these strategies and enhance our ability to develop effective programs for cultural groups. The authors illustrate this new approach with an example of cultural tailoring forcancer prevention in a population of lower income urban African American women.

The self-reported likelihood of patient delay in breast cancer: new thoughts for early detection

BACKGROUND

Delayed presentation of self-discovered breast symptoms influences stage of cancer at diagnosis and decreases breast cancer survival.

METHODS

A total of 699 asymptomatic women (black, white, and Latino), recruited in community settings and stratified by age, income, and educational level, were surveyed for their likelihood to delay (J-Delay scale) in the event of a breast symptom discovery. Models of likelihood were tested with logistic regression analyses.

RESULTS

A total of 166 women (23.7%) reported likelihood to delay. Lower income, lower educational level, self identification as Latino or black, experienced prejudice in care delivery, perceived lack of access to health care, fatalism about breast cancer, poor health care utilization habits, self-care behavior, spouse/partner and employer perceived constraints, problem-solving style, and a lack of knowledge of breast cancer's presenting symptoms were associated with likelihood to delay. A combined sample multiple logistic regression model correctly predicted 40.6% of women reporting a likelihood to delay, 94.9% of those not likely to delay, and 82.4% (551 of 669) of cases overall.

CONCLUSIONS

Self-reported likelihood of patient delay is measurable in advance of symptom occurrence, and this measure is consistent with behavioral and knowledge variables previously linked with advanced breast cancer at diagnosis.

Ethnic differences in quality of life among early breast and prostate cancer survivors

This study assessed quality of life (QOL) in recently diagnosed breast and prostate cancer patients of European American and Asian Pacific Islanders (specifically, individuals of Filipino, Japanese, and Native Hawaiian ancestry) to investigate whether QOL varied according to ethnicity and the relative importance of ethnicity as a predictor of QOL. Participants were identified through consecutive registrations on the Hawaii Tumor Registry, based on a diagnosis of breast or prostate cancer 4-6 months previously. QOL was measured by the QLQ-C30, a standardized questionnaire widely used in cancer patient populations. Two hundred and twenty-seven individuals participated (101 prostate and 126 breast cancer patients). QOL was similar across ethnic groups in most areas of QOL. However, differences were found in several areas, all in the direction of Filipino patients reporting worse outcomes. Hierarchical stepwise regressions supported the importance of ethnicity, controlling for clinical and demographic predictors. We conclude that additional research is needed to understand the relationship between ethnicity and QOL in cancer survivors.

Adherence of low-income women to cancer screening recommendations

BACKGROUND

African-American and low-income women have lower rates of cancer screening and higher rates of late-stage disease than do their counterparts.

OBJECTIVE

To examine the effects of primary care, health insurance, and HMO participation on adherence to regular breast, cervical, and colorectal cancer screening.

DESIGN

Random-digit-dial and targeted household telephone survey of a population-based sample.

SETTING

Washington, D.C. census tracts with > or =30% of households below 200% of federal poverty threshold.

PARTICIPANTS

Included in the survey were 1,205 women over age 40, 82% of whom were African American.

MAIN OUTCOME MEASURES

Adherence was defined as reported receipt of the last 2 screening tests within recommended intervals for age.

RESULTS

The survey completion rate was 85%. Overall, 75% of respondents were adherent to regular Pap smears, 66% to clinical breast exams, 65% to mammography, and 29% to fecal occult blood test recommendations. Continuity with a single primary care practitioner, comprehensive service delivery, and higher patient satisfaction with the relationships with primary care practitioners were associated with higher adherence across the 4 screening tests, after considering other factors. Coordination of care also was associated with screening adherence for women age 65 and over, but not for the younger women. Compared with counterparts in non-HMO plans, women enrolled in health maintenance organizations were also more likely to be adherent to regular screening (e.g., Pap, odds ratio [OR] 1.89, 95% confidence interval [CI] 1.11 to 3.17; clinical breast exam, OR 2.04, 95% CI 1.21 to 3.44; mammogram, OR 1.95, 95% CI 1.15 to 3.31; fecal occult blood test, OR 1.70, 95% CI 1.01 to 2.83.)

CONCLUSIONS

Organizing healthcare services to promote continuity with a specific primary care clinician, a comprehensive array of services available at the primary care delivery site, coordination among providers, and better patient-practitioner relationships are likely to improve inner-city, low-income women's adherence to cancer screening recommendations.

Protegiendo Nuestra Comunidad: empowerment participatory education for HIV prevention

To be effective, HIV/AIDS interventions must be culturally and linguistically appropriate and must occur within the context of the specific community in which they are delivered. In this article, the development of a culture-specific lay health advisor (LHA) program, Protegiendo Nuestra Comunidad, for recently immigrated Mexicans is described. This program is one component of a collaborative inquiry research project involving community participants and researchers working as partners in carrying out and assessing a program for the prevention of HIV/AIDS. The collaborative inquiry process was applied as an empowerment philosophy and methodology of Paulo Freire and an ecological framework was used for the development of Protegiendo Nuestra Comunidad. The use of principles of empowerment for curriculum development, teaching methodology, and program delivery are described.

Community-based cancer screening for underserved women: design and baseline findings from the Breast and Cervical Cancer Intervention Study

BACKGROUND

Underutilization of breast and cervical cancer screening has been observed in many ethnic groups and underserved populations. Effective community-based interventions are needed to eliminate disparities in screening rates and thus to improve prospects for survival.

METHODS

The Breast and Cervical Cancer Intervention Study was a controlled trial of three interventions in the San Francisco Bay Area from 1993 to 1996: (1) community-based lay health worker outreach; (2) clinic-based provider training and reminder system; and (3) patient navigator for follow-up of abnormal screening results. Study design and a description of the interventions are reported along with baseline results of a household survey conducted in four languages among 1599 women, aged 40-75.

RESULTS

Seventy-six percent of women ages 40 and over had had at least one mammogram, and most had had a clinical breast examination (88%) and Pap smear (89%). Rates were significantly lower for non-English-speaking Latinas and Chinese women (56 and 32%, respectively, for mammography), and maintenance screening (three mammograms in the past 5 years) varied from 7% (non-English-speaking Chinese) to 53% (Blacks). Pap smear screening in the past 3 years was low among non-English-speaking Latinas (72%) and markedly lower among non-English-speaking Chinese women (24%). The strongest predictors of screening behavior were having private health insurance and frequent use of medical services. Having a regular clinic and speaking English were also important. Race/ethnicity, education, household income, and employment status were, overall, not significant predictors of screening behavior.

CONCLUSIONS

These baseline results support the importance of cancer screening interventions targeted to persons of foreign origin, particularly those less acculturated.

Quality of data in multiethnic health surveys

OBJECTIVE

There has been insufficient research on the influence of ethno-cultural and language differences in public health surveys. Using data from three independent studies, the authors examine methods to assess data quality and to identify causes of problematic survey questions.

METHODS

Qualitative and quantitative methods were used in this exploratory study, including secondary analyses of data from three baseline surveys (conducted in English, Spanish, Cantonese, Mandarin, and Vietnamese). Collection of additional data included interviews with investigators and interviewers; observations of item development; focus groups; think-aloud interviews; a test-retest assessment survey; and a pilot test of alternatively worded questions.

RESULTS

The authors identify underlying causes for the 12 most problematic variables in three multiethnic surveys and describe them in terms of ethnic differences in reliability, validity, and cognitive processes (interpretation, memory retrieval, judgment formation, and response editing), and differences with regard to cultural appropriateness and translation problems.

CONCLUSIONS

Multiple complex elements affect measurement in a multiethnic survey, many of which are neither readily observed nor understood through standard tests of data quality. Multiethnic survey questions are best evaluated using a variety of quantitative and qualitative methods that reveal different types and causes of problems.

Perceived risk and help-seeking behavior for breast cancer. A Chinese-American perspective

Delay in the diagnosis and treatment of breast cancer diminishes a woman's chance of survival. How do women decide whether and when to seek an evaluation of breast symptoms that may signal breast cancer? Prior studies of African-American, white, and Latino women have described a number of critical factors associated with making the judgment to delay, but at this writing, there have been no studies factors influencing Chinese-American women. By means of focus group methods in English, Mandarin, and Cantonese, a sample of 45, predominantly first-generation Chinese-American women explained their understanding of breast cancer risk and their likelihood of delaying versus seeking evaluation of self-discovered breast symptoms. There was much congruence with the ideas of other American women despite the differing cultural heritage. Unique to these Chinese Americans was a sense of invulnerability to breast cancer, a linking of cancer to tragic luck, and the predominant likelihood of delay. To preserve modesty and to conserve wealth and time, many study participants favored using Chinese medicine and delaying Western therapies. This study suggests ways by which health care providers must approach guidelines for breast cancer early detection in this population.

Randomized trial testing the effect of peer education at increasing fruit and vegetable intake

BACKGROUND

The National Cancer Institute recommends that Americans eat at least five daily servings of fruits and vegetables. National strategies to increase consumption may not reach minority and lower socioeconomic populations. In a randomized trial, peer education was tested for effectiveness at increasing fruit and vegetable intake among lower socioeconomic, multicultural labor and trades employees.

METHODS

Employees (n = 2091) completed a baseline survey and received an 18-month intervention program through standard communication channels (e.g., workplace mail, cafeteria promotions, and speakers). Ninety-three social networks (cliques) of employees were identified, which were pair matched on intake. At an interim survey (during months 8 and 9), 11 cliques no longer existed and 41 matched pairs of cliques containing 905 employees remained, with one clique per pair being randomly assigned to the peer education intervention. Employees who were central in the communication flow of the peer intervention cliques served as peer educators during the last 9 months of the intervention program. Fruit and vegetable intake was measured with 24-hour intake recall and with food-frequency questions in baseline, outcome (i.e., at 18 months), and 6-month follow-up surveys. All P values are two-sided.

RESULTS

By use of multiple regression, statistically significant overall effects of the peer education program were seen in the intake recall (increase of 0.77 total daily servings; P<.0001) and the food-frequency (increase of 0.46 total daily servings; P =.002) questions at the outcome survey. The effect on the total number of servings persisted at the 6-month follow-up survey when measured by the intake recall (increase of 0.41 total daily servings; P =.034) but not the food-frequency (decrease of 0.04 total daily servings; P =.743) questions.

CONCLUSIONS

Peer education appears to be an effective means of achieving an increase in fruit and vegetable intake among lower socioeconomic, multicultural adult employees.

Narratives of breast symptom discovery and cancer diagnosis: psychologic risk for advanced cancer at diagnosis

In spite of cancer screening programs, women continue to present with advanced breast cancer. How do women decide whether and when to seek an evaluation for self-discovered symptoms? This study examined 104 narratives told by 80 Anglo-, Latina-, and African-American women who participated in 1 of 16 community-based focus groups. The women's narratives contained powerful thematic messages about breast cancer and their expected behavior in the event of a self-discovered breast symptom. Narrative explanations that predicted an increased likelihood of advanced disease at diagnosis included these factors: incorrect symptom attributions and risk estimations; reluctance to consider the threat posed by the symptom; failure to tell another person about the symptom; and expectations of abandonment by male partners, deportation, prejudice, and refusal of treatment due to poverty. Stories of advanced breast cancer also told of reliance on alternative healing, concerns about overwhelming family resources, and extreme modesty that inhibited obtaining a physical examination. Interventions aimed at earlier detection of breast cancer must connect with the beliefs and assumptions embedded in these narratives, provide pragmatic solutions for perceived constraints on seeking evaluations of self-discovered symptoms, and explore the use of community narratives to confirm the value of early detection of breast cancer.

Opening pathways to cancer screening for Vietnamese-American women: lay health workers hold a key

PURPOSE

We describe a controlled trial of a community outreach intervention to promote recognition, receipt, and screening-interval maintenance of clinical breast examinations (CBE), mammograms, and Pap smears among Vietnamese-American women.

METHODS

Over a 3-year period, indigenous lay health workers conducted small-group sessions of Vietnamese women in a low-income district of San Francisco, California. Women in Sacramento, California, served as controls. Lay workers conducted 56 sessions on general prevention, 86 on cervical cancer, and 90 on breast cancer. Surveys of 306 to 373 women were conducted in the study communities in 1992 and 1996.

RESULTS

In the intervention community, recognition of screening tests increased significantly between pre- and postintervention surveys: CBE, 50 to 85%; mammography, 59 to 79%; and Pap smear, 22 to 78% (P = 0.001 for all). Receipt of screening tests also increased significantly: CBE, 44 to 70% (P = 0.001); mammography, 54 to 69% (P = 0.006); and Pap smear, 46 to 66% (P = 0.001). Best-fitting logistic regression models, adjusting for preintervention rates and significant covariates, also showed statistically significant odds ratios for the intervention effect (P < 0.0001).

CONCLUSIONS

Trained Vietnamese lay health workers significantly increased Vietnamese women's recognition, receipt, and maintenance of breast and cervical cancer screening tests.

A randomized community trial to increase mammography utilization among low-income women living in public housing

BACKGROUND

A randomized trial was conducted to evaluate the impact of a community-based intervention on mammography use among low-income women living in public housing.

METHODS

All 41 public housing high-rise buildings were randomized to treatment and delayed treatment (control) conditions. After a cross-sectional baseline survey, an intervention called Friend to Friend was conducted in the treatment buildings by American Cancer Society and building resident volunteers. The intervention consisted of a health professional talk, small group discussions, and an opportunity to request assistance in obtaining a mammogram or mammogram reminder. A second cross-sectional survey was conducted to measure differences in screening rates between the study groups.

RESULTS

Participation in the intervention averaged 27%. The study groups were equivalent at baseline. At follow-up, the proportion of women age 50-79 years who reported mammography screening in the previous 15 months was significantly higher in the treatment group (64%) than in the control group (52%). Breast cancer knowledge, attitudes, and beliefs did not differ between groups.

CONCLUSIONS

These findings suggest that a multidimensional intervention which reaches women within their social environment and uses community volunteers can increase mammography utilization among women in public housing.
