Clinical, demographic, and psychological characteristics of new, asymptomatic participants in a transvaginal ultrasound screening program for ovarian cancer

BACKGROUND: Attitudinal, mood, and personality variables have been identified as predictors of uptake of routine screening for a variety of cancers, including those of the breast, cervix, and colon. Little information exists, however, regarding characteristics of participants in ovarian cancer (OC) screening. METHOD: Asymptomatic women (n = 312; mean age = 57.45 years; range = 26-80) were assessed immediately before undergoing an initial transvaginal sonography (TVS) screening test for ovarian cancer (OCS group). Their responses were compared to identical information obtained from an age- and education-matched group of women with no history of screening for OC (HC group). All respondents completed measures of OC-related attitudes, knowledge, beliefs and risk perceptions, dispositional characteristics (informational coping style and dispositional optimism), and psychological distress. RESULTS: Analyses revealed the OCS group was characterized not only by more OC-specific distress and a more extensive family history of OC but also by less optimism and less knowledge of OC risk factors. Group membership was unrelated to beliefs about the efficacy of TVS screening. CONCLUSION: Results have implications for development of programs to increase appropriate participation in OC screening programs.     

Knowledge, Attitudes, and Interest in Breast-Ovarian Cancer Gene Testing: A Survey of a Large African-American Kindred with a BRCA1 Mutation

BACKGROUND: This study assessed counseling and testing needs from the perspective of adult members of a large African-American kindred with a BRCA1 mutation. METHODS: Interviews were conducted with 95 male and female kindred members to elicit information on sociodemographics, attitudes toward health care providers, breast cancer screening behaviors, and religious/spiritual beliefs, as well as to evaluate psychological distress, beliefs, knowledge, and attitudes related to genetic testing. RESULTS: Knowledge about breast and ovarian cancer genetics was limited. Adherence to screening recommendations was low among females with no personal breast or ovarian cancer history. The majority (67%) wished to discuss risk factors with a health care provider. Most participants (82%) indicated that they would have a genetic test if it were available. Significant predictors of intent to undergo testing were having at least one first-degree relative with breast and/or ovarian cancer (OR = 5.1; 95% CI = 1.2-20.9) and perceived risk of being a gene carrier > or =50% (OR = 64.3; 95% CI = 5.1-803.9) or reporting that they did not know their risk of being a gene carrier (OR = 10.9; 95% CI = 2.1-57.7). Cited barriers to testing included cost and availability. CONCLUSION: There is a high interest level in genetic testing despite limited knowledge about cancer genetics among these high-risk African Americans. Our study provides information for designing a genetic education and counseling intervention for this and similar families.     

Effect of a media-led education campaign on breast and cervical cancer screening among Vietnamese-American women

BACKGROUND: Previous research has shown that breast and cervical cancer screening rates are low among Vietnamese women. METHODS: Over a 24-month period, we implemented a media-led community education campaign to promote recognition, intention, receipt, and currency of routine checkups, clinical breast examinations, mammograms, and Pap tests among Vietnamese-American women in Alameda and Santa Clara Counties in northern California. Women in Los Angeles and Orange Counties in southern California served as controls. To evaluate its impact, pretest telephone interviews were conducted of 451 randomly selected women in the intervention area and 482 women in the control area and posttest interviews with 454 and 422 women, respectively. RESULTS: At posttest, after controlling for demographic differences in the surveyed populations, the odds ratios for the intervention effect were statistically significant for having heard of a general checkup, Paptest, and clinical breast examination (CBE); planning to have a checkup, Pap test, CBE, and mammogram; and having had a checkup and Pap test. The intervention had no effect on being up to date for any of the tests. CONCLUSIONS: A media-led education intervention succeeded in increasing recognition of and intention to undertake screening tests more than receipt of or currency with the tests.     

The effect of an illustrated pamphlet decision-aid on the use of prostate cancer screening tests

BACKGROUND: Prostate cancer screening with serum prostate-specific antigen (PSA) and digital rectal examination (DRE) continues to increase. Our goal was to test the effect of a prostate cancer screening decision-aid on patients' knowledge, beliefs, and use of prostate cancer screening tests. METHODS: Our study was a randomized controlled trial of a prostate cancer screening decision-aid consisting of an illustrated pamphlet as opposed to a comparison intervention. We included 257 men aged 50 to 80 years who were receiving primary care at a Department of Veterans Affairs Hospital in Milwaukee, Wisconsin. The decision-aid provided quantitative outcomes of prostate cancer screening with DRE and PSA. We subsequently evaluated prostate cancer screening knowledge, beliefs, and test use. RESULTS: The illustrated pamphlet decision-aid was effective in improving knowledge of prostate cancer screening tests: 95% of the experimental group were aware of the possibility of false-negative test results compared with 85% of the comparison group (P <.01). Ninety-one percent of the experimental group were aware of the possibility of a false-positive screening test result compared with 65% of the comparison group (P <.01). However, there was no difference in the use of prostate cancer screening between the experimental (82%) and comparison (84%) groups, (P >.05). CONCLUSIONS: When used in a primary care setting, an illustrated pamphlet decision-aid was effective in increasing knowledge of prostate cancer screening tests but did not change the use of these tests.     

Socioeconomic differences in cancer screening participation: comparing cognitive and psychosocial explanations

This paper compares psychosocial and cognitive models of socioeconomic variation in participation in screening for colorectal cancer. The psychosocial model suggests that factors such as higher stress and lower social support explain, in part, why people from lower socioeconomic status (SES) environments are less likely to participate in screening. The cognitive model suggests that beliefs about cancer risk and screening will play an important part in differential participation. In practice both sets of factors may contribute to explaining socioeconomic differentials. The data for these analyses are drawn from a randomised controlled trial of colorectal cancer screening (the UK Flexible Sigmoidoscopy Trial). The participants are from the Scottish centre, where recruitment was stratified to generate a socioeconomically diverse sample. The dependent variable was interest in attending screening. A questionnaire covering demographic status, psychosocial and cognitive factors as well as interest in screening was sent to 10,650 adults. The results showed the predicted SES gradient in interest. There were also SES differences in both psychosocial and cognitive variables. A series of logistic regression models were used to test potential mediators of the association between SES and interest in attending screening by successively including psychosocial factors, cognitive factors, and then both, in the equation. Only the inclusion of the cognitive variables significantly reduced the variation associated with SES, providing better support for the cognitive than the psychosocial model.     

Accuracy of self-reports of fecal occult blood tests and test results among individuals in the carpentry trade

BACKGROUND: Inaccuracy in self-reports of colorectal cancer (CRC) screening procedures (e.g., over- or underreporting) may interfere with individuals adhering to appropriate screening intervals, and can blur the true effects of physician recommendations to screen and the effects of interventions designed to promote screening. We assessed accuracy of self-report of having a fecal occult blood test (FOBT) within a 1-year window based on receipt of FOBT kits among individuals aged 50 and older in the carpentry trade (N = 658) who were off-schedule for having had a FOBT. METHOD: Indices of evaluating accuracy of self-reports (concordance, specificity, false-positive and false-negative rates) were calculated relative to receipt of a mailed FOBT. Among those who mailed a completed FOBT, we assessed accuracy of reporting the test result. RESULTS: Participants underestimated having performed a FOBT (false-negative rate of 44%). Accuracy was unrelated to perceptions of getting or worrying about CRC or family history. Self-reports of having a negative FOBT result more consistently matched the laboratory result (specificity 98%) than having a positive test result (sensitivity 63%). CONCLUSIONS: Contrary to other findings, participants under- rather than over reported FOBT screening. Results suggest greater efforts are needed to enhance accurate recall of FOBT screening.     

Mass population screening for colorectal cancer: factors influencing subjects' choice of screening test

OBJECTIVES: To identify socio-demographic, economic, medical and attitudinal factors that explain subjects' choice of test for screening for colorectal cancer (biennial faecal occult blood test versus once-only flexible sigmoidoscopy). METHODS: Data obtained from a questionnaire, administered by general practitioners and returned by approximately 2700 asymptomatic subjects. Thereafter, logistic regression modelling to explain willingness to participate in screening, whether or not a test preference is expressed, and the nature of the preference. RESULTS: An interest in undertaking screening is more probable if the subject is white, older, married and possesses a high health motivation. An intention to participate is more probable if the subjects are particularly worried about the disease, feel themselves to be particularly susceptible to it, and have already had experience of screening for colorectal and (if female) other cancers. Persons in receipt of a household income below 10,000 Pounds are less likely to express an interest in screening. Women are more likely to express a test preference and this preference is more likely to be for the faecal occult blood test. Subjects' worries and perception of risk are associated with reported experiences of cancer, stomach problems and depression. A positive attitude towards screening is positively associated with frequency of dental visits. CONCLUSIONS: Socio-demographic, economic and other factors evidently influence subjects' preferences for particular screening tests and, by implication, the likelihood of compliance with any future screening offer. The models support the view that participation in colorectal cancer screening has as much to do with a positive attitude towards health and health promotion generally as with any specific concern about the disease.     

A history of interpersonal trauma and the gynecological exam

Cervical cancer is preventable, in part, by routine Papanicolaou (Pap) testing, but some women avoid routine screening. African American women have the greatest mortality among all groups of women in the United States. Personal reasons have been found to contribute to screening avoidance behavior, such as a history of sexual abuse and intimate partner violence. Fifteen African American women with a trauma history participated in personal interviews. The Interaction Model of Client Behavior was employed for exploring the women's social influence, previous health care experience, cognitive appraisal, affective response, and motivation associated with routine Pap testing. Study findings suggest that providers need to assess and provide accurate information about Pap testing and cervical cancer to increase patients' knowledge. Personally reflecting on one's approach to conducting a woman's gynecologic exam (and how it is performed) might prevent triggering unwanted memories, making that visit a positive experience and facilitating repeat screening behavior.     

Receipt of preventive services by elders based on composite measures, 1997-2004

BACKGROUND: The receipt of routine vaccinations and cancer screening is typically tracked separately. Monitoring trends in this way does not measure the overall protection conferred by these services on a target population. DESIGN: Telephone surveys were conducted in 1997, 2002, and 2004 as part of the Behavioral Risk Factor Surveillance System. SETTING/PARTICIPANTS: Randomly selected adults aged 65 and older from 49 states and Washington DC. MAIN OUTCOME MEASURES: Statistically significant changes (p <0.05) in a composite measure of the prevalence of U.S. men aged 65 or older who were up to date with recommendations for colorectal cancer screening, influenza vaccination, pneumococcal vaccination; and for the prevalence of U.S. women aged 65 or older who were up to date for these measures as well as for Pap test and screening mammography. RESULTS: The percentage of men who reported being up to date on all tests increased from 24.4% (1997) to 39.6% (2002) to 41.0% (2004), and the percentage of women increased from 18.6% (1997) to 32.4% (2002) to 32.5% (2004). For both groups, results varied by education, race/ethnicity, marital status, insurance status, and state, as well as whether they had a personal doctor. CONCLUSIONS: Despite increases between 1997 and 2004 in the reported receipt of individual cancer screenings and vaccinations among U.S. adults aged 65 or older, approximately seven of ten women and six of ten men were not up to date on these routine preventive services in 2004.     

Knowledge, beliefs, and barriers relevant to colorectal cancer screening in an urban population: a pilot study

A sample of 115 urban, working-class, predominantly minority men and women was interviewed by telephone to assess knowledge, beliefs, and barriers relevant to colorectal cancer (CRC) and CRC screening. More than half (53.9%) were unable to name a CRC screening test. Misconceptions were common. Dispelling inaccurate beliefs, establishing an individual's preference for fecal occult blood tests or flexible sigmoidoscopy, and helping individuals take a proactive role in the receipt of CRC screening are important goals for health education efforts aimed at increasing rates of CRC screening. Participants' willingness to engage in detailed telephone conversations about CRC and CRC screening was encouraging.     

Psychological impact of predicting individuals’ risks of illness: a systematic review

The aim of this review is to determine the frequency and circumstances under which predicting individuals’ risk of illness has adverse psychological effects. Using systematic review methodology, the literature was searched for studies that had assessed the adverse psychological outcomes of risk assessment programmes. The outcomes investigated are emotional (anxiety, depression, distress) cognitive (intrusive thoughts, perceptions of health) and behaviour (work absenteeism). The impact of both positive and negative test results are summarised in terms of the number of studies showing significant effects between and within groups in the short (one month or less) and longer term (more than one month). Where sufficient data were available, a meta-analysis was conducted to assess effect size. Fifty-four studies met the criteria for inclusion. The studies assessed the impact of informing individuals about cardiovascular risk (21), risk of AIDS (eight), risk of cancer (10), risk of Huntington’s disease (10), risk of diabetes (two), risk of spinocerebellar ataxia (one) and risk of osteoporosis (two). Overall, the quality of studies assessed was limited, with only two using a randomised design to determine the psychological impact of risk assessment. Receiving a positive test result was associated in the short term in the great majority of studies with depression, anxiety, poorer perceptions of health and psychological distress. Data were available for a quantitative synthesis of results on three outcomes, anxiety, depression and distress. Anxiety and depression were significantly higher in those tested positive compared with those tested negative in the short term but not the longer term. Distress could only be assessed in the longer term: there was no evidence of an increase for those receiving positive test results. The five experimental studies that reported interventions aimed at preventing some of these adverse effects all reported favourable results. There was little evidence of any adverse psychological effects of receiving an unfavourable test result. Adverse psychological effects are a common immediate consequence of positive test results following risk assessment. Results from the few experimental studies reviewed suggest that these adverse outcomes should not be seen as inevitable.

Predictors of breast cancer screening in a panel study of African American women.

PURPOSE: This study examines the predictors of breast cancer screening participation in a panel study of African American women over age 40. We examine the effect of depression, age, beliefs and concerns about breast cancer and its risk, communication with social networks regarding screening, marital status, participation in religious organizations, breast cancer family history, and participation in a breast cancer education program. METHODS: Participants were recruited from 30 African American churches, two low-income housing projects, and from a health fair at a historically African American University (N = 364). Participants were interviewed upon recruitment, and three months later. Multinomial logistic regression models are estimated to assess the relative impact of covariates on the odds of getting a mammogram while controlling for other factors. We also assess predicted probabilities of screening at specific levels of covariates. RESULTS: We find that age, marriage, an educational intervention, talking with friends, and believing that early detection can lead to cure had a positive impact on getting a mammogram between T1 and T2. In contrast, depression significantly reduces the odds of getting a mammogram. Family histories of breast cancer and church participation have no effect on rates of mammography net of other factors.     

"Coming to grips" with chemotherapy-induced premature menopause

Chemotherapy for early stage breast cancer has significantly improved survival outcomes but is associated with ovarian toxicity, resulting in early menopause for many premenopausal women. A qualitative study was conducted that generated a grounded theory explaining how women carried on with life in response to breast cancer and menopause. My purpose in this article is to describe three distinct types of responses from women in that study: making the best of it, struggling and barely noticing. The degree of menopausal symptom distress and perceived level of preparation for the menopause experience had the greatest influence on the type of response.     

The influence of socio-cultural factors on breast cancer screening behaviors in Lagos,Nigeria

Culture has been shown to influence health beliefs and health-related behaviors by influencing the type of health information to which women have been exposed and shapes health and illness perceptions and practices. To increase screening rates, cultural influences should be considered as important correlates of screening behaviors for breast cancer. This study used semi-structured interviews of women attending a cancer screening facility in Lagos, Nigeria guided by the PEN-3 model to describe culturally relevant factors that shape attitudes toward breast cancer and breast cancer screening. Religion was the most prominent theme and was shown to have positive, negative and existential effect on breast cancer perceptions. Other major themes observed were related to family and traditional beliefs. The results from this study could be used to develop and implement culturally relevant cancer prevention interventions, strategies, and recommendations to overcome screening barriers in an effort to increase breast cancer participation and awareness among Nigerian women.     

The Effect of Presenting Information about Invasive Follow-Up Testing on Individuals’ Noninvasive Colorectal Cancer Screening Participation Decision: Results from a Discrete Choice Experiment

ObjectivesMany national colorectal cancer screening campaigns have a similar structure. First, individuals are invited to take a noninvasive screening test, and, second, in the case of a positive screening test result, they are advised to undergo a more invasive follow-up test. The objective of this study was to investigate how much individuals’ participation decision in noninvasive screening is affected by the presence or absence of detailed information about invasive follow-up testing and how this effect varies over screening tests.MethodsWe used a labeled discrete choice experiment of three noninvasive colorectal cancer screening types with two versions that did or did not present respondents with detailed information about the possible invasive follow-up test (i.e., colonoscopy) and its procedure. We used data from 631 Dutch respondents aged 55 to 75 years. Each respondent received only one of the two versions (N = 310 for the invasive follow-up test information specification version, and N = 321 for the no-information specification version).ResultsMixed logit model results show that detailed information about the invasive follow-up test negatively affects screening participation decisions. This effect can be explained mainly by a decrease in choice shares for the most preferred screening test (a combined stool and blood sample test). Choice share simulations based on the discrete choice experiment indicated that presenting invasive follow-up test information decreases screening participation by 4.79%.ConclusionsDetailed information about the invasive follow-up test has a negative effect on individuals’ screening participation decisions in noninvasive colorectal cancer screening campaigns. This result poses new challenges for policymakers who aim not only to increase uptake but also to provide full disclosure to potential screening participants.     

Participation in fecal occult blood screening: a critical review

The factors that influence participation in fecal occult blood screening for colorectal cancer are poorly understood. A better understanding of these factors could lead to better screening products or to educational approaches to increase participation with currently available products. In this article, we review findings from studies that have examined the determinants of participation in fecal occult blood screening. Two components of participation are identified: initial agreement to participate and subsequent compliance with the testing procedures. We conclude that the factors that lead to agreement often differ from those that lead to compliance. Following the literature review, we discuss ways in which recent advances in attitude and behavior research might be used to improve future investigations of the determinants of participation in fecal occult blood screening. Specifically, this research suggests that investigators should focus on beliefs and attitudes associated with the perceived consequences of screening participation rather than on other types of beliefs and attitudes; measure beliefs and attitudes at the same level of specificity as behavior; and distinguish between individuals' initial agreement to participate in screening and their actual participation.     

Mediation of the Effects of the Family Bereavement Program on Mental Health Problems of Bereaved Children and Adolescents

This study presents an analysis of mediation of the effects of the Family Bereavement Program (FBP) to improve mental health outcomes of girls at 11 months following program participation. The FBP was designed based on a theory that program-induced change in multiple child and family level mediators would lead to reductions in children's mental health problems. Mediational models were tested using a three wave and a two wave longitudinal design. Using a three wave longitudinal design, FBP effects on three variables at T2 (increased positive parenting, decreased negative events, and decreased inhibition of emotional expression) were found to mediate the effects of the FBP on mental health problems at 11-month follow-up. Using a two-wave longitudinal design, support was found for FBP effects on three additional variables at 11-month follow-up (increased positive coping, decreased negative thoughts about stressors, and decreased unknown control beliefs) to mediate program effects to reduce mental health problems at 11-month follow-up. The discussion focuses on theoretical explanations for the mediational effects and on implications for identifying "core components" of the FBP that are responsible for its effects to reduce mental health problems of girls.     

Fatalistic Beliefs and Cervical Cancer Screening Among Mexican Women

Fatalistic beliefs about cervical cancer were studied in 464 Mexican women, and how such beliefs relate to participation in cervical cancer screening was evaluated. Rural women were less likely than urban women to have had a Pap test and more likely to believe that the illness is due to bad luck or fate. These were also the beliefs most associated with nonscreening among rural women, whereas for urban women the belief most associated with nonscreening was “there is not much I can do to prevent cervical cancer.”
