Factors Affecting Mammography Behavior and Intention Among Korean Women

Comparison of competitive cognitive models in explanation of women breast cancer screening behaviours using structural equation modelling: Health belief model and theory of reasoned action

INTRODUCTION

The efficacy of the theory of reasoned action (TRA), compared with the health belief model (HBM), has not been fully elucidated in screening practices.

METHODS

This population-based cross-sectional study was conducted with samples of 500 women aged 35-85 years, in the north of Iran. The data of demographic characteristics, awareness, health belief, subjective norms and screening behaviours were collected using standard instruments. Structural equation modelling (SEM) was applied to estimate the pathways of regression coefficients.

RESULTS

The model that incorporated the health belief and the standardised coefficient of the knowledge scores influenced significantly on the health belief perception (beta = 0.375), and consequently, the health belief directly affected screening behaviours (beta = 0.73). In contrast, In TRA model, while the direct effect of knowledge on intention was negligible it has a greater indirect effect by mediating health belief and subjective norms (indirect beta = 0.35) on behaviour intention. A high coefficient of intention was observed by subjective norms (beta = 0.626), and the intention has a great positive effect on screening behaviour (beta = 0.601). All fitting indexes were quietly improved in the TRA model as compared with HBM.

CONCLUSION

Thus, the unifying structure of knowledge, health belief, subjective norms and intention improves the predictor power in breast cancer screening behaviours.

Socio-Cognitive Determinants of the Mammography Screening Uptake among Iranian Women

Background: Mammography screening uptake is the most effective method in breast cancer screening. The aim of this study was to determine the determinants related to mammography screening uptake among Iranian women based on the theory of planned behavior. Materials and Methods: This cross-sectional study was conducted among 408 women who referred to health centers in Kermanshah city, the western of Iran, during 2016. Participants filled out a self-administered questionnaire. Data were analyzed by SPSS version 21 using Pearson correlation, linear and logistic regression statistical tests at 95% significant level. Results: The mean age of participants was 39.61 years [SD: 8.28], ranged from 30 to 60 years. Almost 13% of the participants had already mammography screening uptake at least once. Perceived behavioral control (OR=1.229) and behavioral intention (OR=1.283) were the more influential predictors on mammography screening uptake. Conclusions: Based on result, it seems increase perceived behavior control toward mammography screening uptake may be usefulness in promotion of mammography screening uptake among Iranian women.

Cancer screening in Koreans: a focus group approach

BACKGROUND

Cancer is the greatest disease burden in Korea. Cancer screening can reduce the burden of cancer but cancer screening rates among Koreans remain low. The purposes of this study were to a) understand Koreans' beliefs and knowledge about cancer screening, and b) explore preferred strategies for increasing cancer screening utilization.

METHODS

We conducted a descriptive, qualitative study using eight face-to-face focus groups with a total of 64 Koreans aged 40 and over. Participants answered semi-structured, open-ended questions assessing their experiences with, and beliefs, knowledge, and opinions about, cancer screening. All interview data were recorded and analyzed in the context of the health belief model (HBM).

RESULTS

The most important themes that emerged from the focus group data were (a) perceived susceptibility (most of the participants believed they were not susceptible to cancer; those who perceived themselves susceptible to cancer were reluctant to express it); (b) perceived benefits (early detection and feelings of relief after cancer screening were benefits; participants had screening because they wanted to take advantage of the Korean government's Medical Payment Support program for cancer patients who have participated in the National Cancer Screening program); (c) perceived barriers (no symptoms; self-care when having symptoms; widespread distrust of tests, doctors, and hospitals; unkind health care providers; the financial burdens of advanced cancer screening tests; and the discomfort during cancer screening); and (d) knowledge of the causes of cancer (incorrect knowledge including beliefs that stress, personality, and body overuse cause cancer). Almost all of the participants were very knowledgeable about the seriousness of cancer and were confident that they were able to have cancer screening. Participants preferred strategies of cancer screening using group interventions with family or friends; various information delivery methods; information emphasizing the importance of cancer prevention; convenient, free, or inexpensive services; and kind health care providers.

CONCLUSIONS

This HBM-based research suggests that beliefs in low susceptibility to cancer, many barriers to cancer screening, and incorrect knowledge should be the foci for increasing cancer screening rates in Koreans. Interventions could change individual cultural beliefs and increase knowledge as well as the quality of health care for Koreans.

Korean American Women and Mammogram Uptake

A high percentage of Korean American (KA) women have never had a mammogram, which puts them at greater risk for late-stage breast cancer. The aim of this study was to compare health beliefs and spousal support about breast cancer and screening between KA women with and without a history of mammogram completion. Cross-sectional data were obtained from 428 non-adherent married KA women. KA women who never had a mammogram were younger, had less access to health care, had less knowledge, and had lower perceived self-efficacy, benefits, and spousal support, and higher perceived barriers to breast cancer screening compared to women who had had a mammogram. Assessing differing characteristics between the two groups of KA women may lead to a better understanding of the variables influencing mammography screening in this population and possibly increase early screening.

Correlates of misperception of breast cancer risk among Korean-American Women

In this study, the authors investigate the factors associated with misperception of breast cancer risk, including unrealistic optimism and unrealistic pessimism, among Korean-American women (KAW). Baseline data were collected between March 2010 and October 2011 from 421 KAW aged 40-65 years who participated in a community-based randomized intervention trial designed to promote breast and cervical cancer screening. Multivariate multinomial regression was performed to identify correlates of misperception of breast cancer risk among KAW. A total of 210 KAW (49.9%) had breast cancer risk perception consistent with their objective risk, whereas 50.1% of KAW in the study had some form of misperception of risk. Specifically, 167 participants (39.7%) were unrealistically optimistic about their own breast cancer risk; 44 (10.5%) were unrealistically pessimistic. In multivariate multinomial logistic regression analysis, living with a partner and higher education were significantly associated with higher odds of having unrealistic optimism. High social support is associated with a lower likelihood of having a pessimistic risk perception. Higher worry is associated with a higher likelihood of having unrealistic pessimism. Misperception of breast cancer risk among KAW and related factors must be considered when developing behavioral interventions for this population.

Psychosocial predictors of adherence to lymphedema risk minimization guidelines among women with breast cancer

BACKGROUND

The effective management of lymphedema risk following breast cancer surgery and treatment requires enactment of simple behavioural strategies, including regularly checking for early lymphedema symptoms. Adopting a broad self-regulatory perspective, our aim for this study was to identify psychological factors associated with adherence to these risk management strategies.

METHODS

Women (N = 98) recently diagnosed with breast cancer and scheduled for breast and lymph node surgery completed questionnaires prior to surgery and at 3 months post-surgery. Variables assessed included demographics, cognitive belief variables in relation to lymphedema and its management (perceived negative consequences, perceived lymphedema controllability, self-efficacy, perceived personal risk, perceived self-regulatory ability to manage risk-related distress), lymphedema knowledge, trait anxiety and adherence to lymphedema risk management recommendations.

RESULTS

Greater adherence was associated bivariately with greater beliefs in lymphedema controllability, self-efficacy, perceived consequences and perceived self-regulatory ability. Linear regression analyses revealed that only greater beliefs in the controllability of lymphedema and self-regulatory ability, as well as greater knowledge, were predictive of greater adherence to risk management strategies.

CONCLUSIONS

This study highlights the importance of underlying beliefs as determinants of whether a woman who is informed and knowledgeable about lymphedema risk and its management will undertake the recommended risk management actions. Along with raising awareness of lymphedema and its risk management, health professionals should promote positive beliefs among women regarding the controllability of lymphedema through early-detection/early-treatment approaches. In addition, educational approaches should aim to enhance a woman's beliefs in her ability to adhere to these risk management recommendations over time.

Increasing mammography and cervical cancer knowledge and screening behaviors with an educational program

PURPOSE/OBJECTIVES

To evaluate the effectiveness of using an educational program based on self-efficacy to increase knowledge and create behavior change regarding recommended mammography and Papanicolaou (Pap) test screening guidelines.

DESIGN

Pretest and post-test, prospective.

SETTING

An urban county in northern Indiana.

SAMPLE

56 women who attended one of four educational programs and 47 women who responded 15 months later.

METHODS

The one-hour educational programs based on self-efficacy included vicarious experiences and verbal persuasion regarding breast and cervical screening practices. Two programs were offered to local church groups as part of a health fair, and two were offered through health promotion initiatives sponsored by private businesses.

MAIN RESEARCH VARIABLES

Demographics, knowledge of breast and cervical cancer, and screening behaviors.

FINDINGS

Knowledge of risk and screening guidelines increased significantly immediately following the educational program (p < 0.001) and did not decrease significantly 15 months later (p = 0.57). Family history and history of human papillomavirus and sexually transmitted diseases were the top known risk factors for breast and cervical cancers, respectively. Participant-reported rates of screening behaviors increased 15 months later for mammography (100%) and Pap test (84%).

CONCLUSIONS

Educational interventions based on self-efficacy increased knowledge of breast and cervical health and helped increase the rate of mammography and Pap tests.

IMPLICATIONS FOR NURSING

Preparing women with strategies to complete a mammogram and Pap test is an important approach to enhancing self-efficacy and increasing screening behaviors.

Influence of demographic factors, knowledge, and beliefs on Jordanian women's intention to undergo mammography screening

PURPOSE

The purpose of this study was to determine the influence of demographic characteristics, breast cancer knowledge, fatalistic beliefs, health beliefs, and subjective norms on Jordanian women's intention to participate in mammography screening.

DESIGN

A cross-sectional survey was used to collect data at 14 comprehensive healthcare centers in Amman and Zarqa, Jordan. A convenience sample of 142 Jordanian women 40 years of age or older with no history of breast cancer and able to read and write in Arabic participated.

METHODS

Self-report surveys included a combination of researcher-designed and existing instruments to measure the study variables. Data were analyzed using descriptive statistics, Pearson's correlation, t tests, and multiple logistic regression.

FINDINGS

Jordanian women surveyed lacked knowledge about breast cancer. Social norms and self-efficacy highly influenced these women's intention to engage in mammography screening. Younger women were more willing to indicate intention to engage in mammographic screening.

CONCLUSIONS

Self-efficacy and the social connectedness of Jordanian society, but not religious beliefs or perceived barriers to screening, influence Jordanian women's intention to undergo mammography. Future research should examine cultural influences, rather than religious beliefs, and investigate Jordanian women's potentially unique perspectives on barriers to actual mammography screening behavior.

CLINICAL RELEVANCE

The prevalence of mammography screening may be enhanced by focusing interventions on Jordanian women's support systems and empowering women by providing knowledge and skills needed to engage in the procedure.

Correlates of mammography utilization among working Muslim Iranian women

Most countries in Middle East have been successful in establishing and furthering basic facilities for screening, diagnosis, and treatment of breast cancer. The rate of compliance with mammography screening, however, remains well below North American and Western European countries. We utilized the Health Belief Model (HBM) to explore factors associated with mammography screening behavior among a sample of 320 Muslim women aged > or = 35. Carrying out this cross-sectional study, we found that screening behavior was associated with older age, higher perceived benefit of breast cancer screening, and lower perceived barrier. Additionally, we demonstrate the importance of religious beliefs in influencing mammography screening behavior and explaining the link between religious involvement and mammography behavior.

Do cultural factors predict mammography behaviour among Korean immigrants in the USA?

AIM

This paper is a report of a study of the correlates of mammogram use among Korean American women.

BACKGROUND

Despite the increasing incidence of and mortality from breast cancer, Asian women in the United States of America report consistently low rates of mammography screening. A number of health beliefs and sociodemographic characteristics have been associated with mammogram participation among these women. However, studies systematically investigating cultural factors in relation to mammogram experience have been scarce.

METHODS

We measured screening-related health beliefs, modesty and use of Eastern medicine in 100 Korean American women in 2006. Hierarchical logistic regression was used to examine the unique contribution of the study variables, after accounting for sociodemographic characteristics.

FINDINGS

Only 51% reported past mammogram use. Korean American women who had previously had mammograms were statistically significantly older and had higher perceived benefit scores than those who had not. Perceived benefits (odds ratio = 6.3, 95% confidence interval = 2.12, 18.76) and breast cancer susceptibility (odds ratio = 3.18, 95% confidence interval = 1.06, 9.59) were statistically significant correlates of mammography experience, whereas cultural factors did not correlate. Post hoc analysis showed that for women with some or good English skills, cultural factors statistically significantly correlated with health beliefs and breast cancer knowledge (P < 0.05).

CONCLUSION

Nurses should consider the inclusion in culturally tailored interventions of more targeted outreach and healthcare system navigation assistance for promoting mammography screening in Korean American women. Further research is needed to unravel the interplay between acculturation, cultural factors and health beliefs related to cancer screening behaviours of Korean American women.

Mammography screening and the theory of planned behavior: suggestions toward an extended model of prediction

Mammography screening is probably the most effective method for the early detection of breast cancer. Existing models of health behavior, such as the theory of planned behavior, could improve their predictive validity and, therefore, their ability to promote health-related interventions by identifying additional factors associated with health decision making. This review provides an overview of research on factors related to mammography screening within the context of the theory of planned behavior and identifies the potential benefits of adding motivational factors, such as time perspective, optimism, and risk perception, in an attempt to enhance its explanatory power.

Does health status influence intention regarding screening mammography?

OBJECTIVE

We analyzed information surveyed from a community-based sample of Korean women older than 40 years of age to understand the relationships between health status and screening behavior.

METHODS

In a cross-sectional population-based study, a two-stage, geographically stratified household-based sampling design was used for assembly of a probability sample of women aged 40-69 years living in Gunpo in Korea, resulting in a total sample size of 503 women. The primary outcome variable for this analysis was the respondent's intention to obtain a mammogram. Predictor variables included health status and other factors known to influence the use of cancer screening, such as age, education, income, marital status and the presence of co-morbid illnesses. Health status was assessed by using the EuroQol (EQ-5D).

RESULTS

The median EQ visual analogue scale score was 75.0, ranging from 20 to 100. In bivariate analyses, the percentage of women reporting to have intention toward mammography use decreased with worsening health status. Women who had problems with mobility or anxiety/depression showed lower intention to undergo future screening mammography. Multivariate logistic regression confirmed that health status was significantly associated with intention toward mammography use. Anxiety or depression was an independent predictor of future screening mammography use.

CONCLUSIONS

Health status is significantly associated with intention regarding screening mammography use. Physicians or other health professionals should be aware that health status is an important component for health promotion, and should pay more attention to clients' possible vulnerability in screening mammography use due to their poor health status.

Behavioral constructs and mammography in five ethnic groups

Intention, self-efficacy, perceived susceptibility, perceived benefits, and subjective norms are key constructs of health behavior theories; their predictive validity for cancer screening has not been ascertained in multiethnic populations. Participants were 1,463 African American, Chinese, Filipina, Latina, and White women aged 40 to 74 interviewed by telephone in their preferred languages. The relationship between baseline constructs and mammography 2 years later was assessed using multivariable logistic regression. Intention predicted mammography overall and among Whites (odds ratio [OR] = 5.0, 95% confidence interval [CI] = 2.4, 10), with racial/ethnic differences in association (p = .020). Self-efficacy predicted mammography overall and among Whites (OR = 3.5, 95% CI = 1.1, 11), with no racial/ethnic interaction. Perceived benefits and subjective norms were associated with screening overall and in some racial/ethnic groups. These results generally support cross-cultural applicability of four of the five constructs to screening with mixed predictive value of measures across racial/ethnic groups. Additional in-depth inquiry is required to refine assessment of constructs.

Unwanted effects of risk notification for breast cancer regarding intention toward mammography utilization

OBJECTIVE

This study was conducted to explore the possible influence of risk notification regarding breast cancer on the intention of women to undergo mammography.

METHODS

This study employed an uncontrolled before-after design. A baseline survey was conducted in a random sample of 1000 women to examine the sociodemographic variables, breast cancer risk factors, and screening-related variables. All subjects received the findings of a personalized health-risk appraisal (HRA) following the baseline interview. After 2 months of the baseline survey, a survey was conducted in 855 women to assess whether the intention of undergoing mammography had changed. Thus, the modification in the intention by communicating the individual risk status was assessed.

RESULTS

There was an overall increase from baseline to post-intervention in the number of subjects with the intention of undergoing mammography. Women in the contemplation and action stages who had intention toward mammography utilization at baseline showed decreased intention regarding mammography. After intervention in the form of HRA to promote mammography utilization, it was determined that young age, being married, being in neither the precontemplation nor the relapse stage, and having one or more risk factors of breast cancer were the predictors of intention to undergo mammography.

CONCLUSIONS

Our findings indicate that communicating the risk status by HRA service can have a negative effect in the promotion of health-conscious behavior. The selection of the appropriate type of intervention using HRA to promote mammography utilization in the target group will be enhanced by taking into account the risk status of each client.

Assess the effects of culturally relevant intervention on breast cancer knowledge, beliefs, and mammography use among Korean American women

A pre-post test, two-group study was conducted to examine the effects of a culturally competent targeted intervention titled GO EARLY Save Your Life on the breast cancer and early screening-related knowledge and beliefs and mammography use among 180 Korean American (KA) women aged 40 years or older who had not had mammograms within the past 12 months. The intervention group received an interactive education session focused on breast cancer, early screening guidelines, and beliefs (breast cancer-related and Korean cultural beliefs). The control group received no education. There was no statistically significant intervention effect on mammography use between the intervention (34%) and control groups (23%) at 24 weeks post baseline. The rates of mammography use for both groups significantly increased from 16 to 24 weeks post baseline. The education was effective in increasing breast cancer/early screening-related knowledge and modifying beliefs (decreasing barriers, fear, seriousness, and fatalism, and increasing preventive health orientation).

Increasing the uptake of cervical screening programmes

Successful cervical screening programmes depend on the degree of coverage and the rate of attendance. There are many demographic reasons why some women fail to attend for cervical screening, including lack of knowledge and education and socioeconomic status. Moreover, a woman's ethnicity and her age also play a role in screening uptake. Community and practice nurses are ideally positioned to identify women's information needs and provide appropriate information to overcome barriers to screening attendance. This article discusses the main predictors of participation in cervical screening programmes and interventions that can be used to increase cervical screening uptake.

Culturally competent training program: a key to training lay health advisors for promoting breast cancer screening

The lay health advisor (LHA) training program for breast cancer screening was conducted among Chinese- English bilingual trainees residing in Southeast Michigan. Guided by Bandura's Social Learning Theory, the development of the training curriculum followed the health communication process recommended by the National Cancer Institute. Data analysis based on questionnaires completed by 79 LHAs indicated that the breast cancer screening training program significantly increased LHAs' knowledge and self-efficacy (p < .01, t test, two-tailed) and LHAs had a positive perception with regard to the training manual. Regression analysis found that LHAs who were younger, employed, and demonstrated a positive perception of the training manual tended to have higher self-efficacy in promoting breast cancer screening (R(2) = .30). This study suggests that a culturally competent training program effectively increases LHAs' self-efficacy. The findings have implications for developing effective LHA training programs in Asian American communities where LHA interventions are rarely implemented.
