Personalised risk communication for informed decision making about taking screening tests

Association of health beliefs and colonoscopy use among survivors of colorectal cancer

OBJECTIVES

Clinical practice guidelines recommend ongoing testing (surveillance) for colorectal cancer survivors because they remain at risk for both local recurrences and second primary tumors. However, survivors often do not receive colorectal cancer surveillance. We used the Health Belief Model (HBM) to identify health beliefs that predict intentions to obtain routine colonoscopies among colorectal cancer survivors.

METHODS

We completed telephone interviews with 277 colorectal cancer survivors who were diagnosed 4 years earlier, between 2003 and 2005, in North Carolina. The interview measured health beliefs, past preventive behaviors, and intentions to have a routine colonoscopy in the next 5 years.

RESULTS

In bivariate analyses, most HBM constructs were associated with intentions. In multivariable analyses, greater perceived likelihood of colorectal cancer (OR = 2.00, 95% CI = 1.16-3.44) was associated with greater intention to have a colonoscopy. Survivors who already had a colonoscopy since diagnosis also had greater intentions of having a colonoscopy in the future (OR = 9.47, 95% CI = 2.08-43.16).

CONCLUSIONS

Perceived likelihood of colorectal cancer is an important target for further study and intervention to increase colorectal cancer surveillance among survivors. Other health beliefs were unrelated to intentions, suggesting that the health beliefs of colorectal cancer survivors and asymptomatic adults may differ due to the experience of cancer.

Neonatologist training to guide family decision making for critically ill infants

OBJECTIVES

To assess neonatology fellow training in guiding family decision making for high-risk newborns and in several critical communication skills for physicians in these scenarios.

DESIGN

A Web-based national survey.

SETTING

Neonatal-perinatal training programs in the United States.

PARTICIPANTS

Graduating fellows in their final month of fellowship.

MAIN OUTCOME MEASURES

Fellows' perceived training and preparedness to communicate with families about decision making.

RESULTS

The response rate was 72%, representing 83% of accredited training programs. Fellows had a great deal of training in the medical management of extremely premature and dying infants. However, they reported much less training to communicate and make collaborative decisions with the families of these infants. More than 40% of fellows reported no communication training in the form of didactic sessions, role play, or simulated patient scenarios and no clinical communication skills training in the form of supervision and feedback of fellow-led family meetings. Fellows felt least trained to discuss palliative care, families' religious and spiritual needs, and managing conflicts of opinion between families and staff or among staff. Fellows perceived communication skills training to be of a higher priority to them than to faculty, and 93% of fellows feel that training in this area should be improved.

CONCLUSIONS

Graduating neonatology fellows are highly trained in the technical skills necessary to care for critically ill and dying neonates but are inadequately trained in the communication skills that families identify as critically important when facing end-of-life decisions.

Uptake in cancer screening programmes

For cancer screening programmes to bring about reductions in mortality, a substantial proportion of the population must participate. Programmes with low uptake can be ineffective and can promote inequalities in health-service provision. Strategies to promote uptake are multifaceted, reflecting differences in the cancers targeted, invitees, health-service contexts, and the tests themselves. Accordingly, there is no universal approach. Strategies should accommodate the many factors that can influence uptake and should incorporate the need to promote informed choice. Screening has the potential to cause harm, and there is an ethical imperative to seek out strategies that provide balanced information on cancer screening. Further research is needed to assess newer approaches to promoting uptake, such as IT-based programmes, and to identify strategies that are balanced, self-sustaining, and affordable.

A meta-analysis of interventions to promote mammography among ethnic minority women

BACKGROUND

Although many studies have been focused on interventions designed to promote mammography screening among ethnic minority women, few summaries of the effectiveness of the interventions are available.

OBJECTIVE

The aim of this study was to determine the effectiveness of the interventions for improving mammography screening among asymptomatic ethnic minority women.

METHODS

A meta-analysis was performed on intervention studies designed to promote mammography use in samples of ethnic minority women. Random-effects estimates were calculated for interventions by measuring differences in intervention and control group screening rates postintervention.

RESULTS

The overall mean weighted effect size for the 23 studies was 0.078 (Z = 4.414, p < .001), indicating that the interventions were effective in improving mammography use among ethnic minority women. For mammography intervention types, access-enhancing strategies had the biggest mean weighted effect size of 0.155 (Z = 4.488, p < .001), followed by 0.099 (Z = 6.552, p < .001) for individually directed approaches such as individual counseling or education. Tailored, theory-based interventions resulted in a bigger effect size compared with nontailored interventions (effect sizes = 0.101 vs. 0.076, respectively; p < .05 for all models). Of cultural strategies, ethnically matched intervention deliveries and offering culturally matched intervention materials had effect sizes of 0.067 (Z = 2.516, p = .012) and 0.051 (Z = 2.365, p = .018), respectively.

DISCUSSION

Uniform improvement in mammography screening is a goal to address breast cancer disparities in ethnic minority communities in this country. The results of this meta-analysis suggest a need for increased use of a theory-based, tailored approach with enhancement of access.

American society of clinical oncology clinical practice guideline update on the use of pharmacologic interventions including tamoxifen, raloxifene, and aromatase inhibition for breast cancer risk reduction

PURPOSE To update the 2002 American Society of Clinical Oncology guideline on pharmacologic interventions for breast cancer (BC) risk reduction. METHODS A literature search identified relevant randomized trials published since 2002. Primary outcome of interest was BC incidence (invasive and noninvasive). Secondary outcomes included BC mortality, adverse events, and net health benefits. An expert panel reviewed the literature and developed updated consensus guidelines. Results Seventeen articles met inclusion criteria. In premenopausal women, tamoxifen for 5 years reduces the risk of BC for at least 10 years, particularly estrogen receptor (ER) -positive invasive tumors. Women < or = 50 years of age experience fewer serious side effects. Vascular and vasomotor events do not persist post-treatment across all ages. In postmenopausal women, raloxifene and tamoxifen reduce the risk of ER-positive invasive BC with equal efficacy. Raloxifene is associated with a lower risk of thromboembolic disease, benign uterine conditions, and cataracts than tamoxifen in postmenopausal women. No evidence exists establishing whether a reduction in BC risk from either agent translates into reduced BC mortality. Recommendations In women at increased risk for BC, tamoxifen (20 mg/d for 5 years) may be offered to reduce the risk of invasive ER-positive BC, with benefits for at least 10 years. In postmenopausal women, raloxifene (60 mg/d for 5 years) may also be considered. Use of aromatase inhibitors, fenretinide, or other selective estrogen receptor modulators to lower BC risk is not recommended outside of a clinical trial. Discussion of risks and benefits of preventive agents by health providers is critical to patient decision making.

Mammography screening after risk-tailored messages: the women improving screening through education and risk assessment (WISER) randomized, controlled trial

AIMS

A randomized trial investigated the impact of risk-tailored messages on mammography in diverse women in the Virginia Commonwealth University Health System's gynecology clinics.

METHODS

From 2003 to 2005, 899 patients > or =40 years of age were randomized to receive risk-tailored information or general information about breast health. Multiple logistic regression analyses summarize their breast health practices at 18 months.

RESULTS

At baseline, 576 (64%) women reported having a mammogram in the past year. At 18-month follow-up, mammography rates were 72.6% in the intervention group and 74.2% in the control group (N.S.). Women (n = 123) who reported worrying about breast cancer "often" or "all the time" had significantly higher mammography rates with the intervention (85.0%) vs. the controls (63.5%). No significant differences existed in clinical breast examination, self-examination, or mammography intentions between the two study arms. However, intervention women with lower education reported significantly fewer clinical breast examinations at follow-up.

CONCLUSIONS

The brief intervention with a risk-tailored message did not have a significant effect overall on screening at 18 months. However, among those who worried, mammography rates in the intervention group were higher. Individual characteristics, such as worry about breast cancer and education status, may impact interventions to improve breast cancer prevention practices.

Measuring, and identifying predictors of women's perceptions of three types of breast cancer risk: population risk, absolute risk and comparative risk

Although a key function of cancer genetics services is to provide risk information, to date there has been little consistency in the way in which breast cancer risk perception has been measured. The aims of the study were to measure estimates of (i) population risk, (ii) absolute risk and (iii) comparative risk of developing breast cancer for Ashkenazi Jewish women, and to determine predictors of breast cancer risk perception. Of 152 women, 107 (70%) completed all questions. The mean (s.d.) estimates for population risk, absolute risk and comparative risk were 22.7% (15.9), 31.8% (20.6) and 1.9-fold (1.9), respectively. Most women overestimated population risk. Women at population risk generally overestimated the population risk and their own absolute risk, yet understood they are at the same risk as the population. Those with a family history understood that they are at increased risk, but underestimated the extent to which their familial risk is increased. Anxiety, high estimation of population risk and lesser family history predicted overestimation of absolute risk, whereas high estimation of population risk and a strong family history predicted underestimation of comparative risk.

Personal communication in primary and secondary cancer prevention: evolving discussions, emerging challenges

Over the past several years, the science of cancer communication has been recognized as integral to the dissemination of cancer prevention and control strategies in both the general population as well as higher-risk groups. In this article we draw upon current literature and small group discussion in the 2008 Society for Behavioral Medicine Cancer Special Interest Group Pre-Conference Workshop on Cancer Communication to identify current findings, critical challenges, and future opportunities regarding personal communication of primary and secondary prevention of cancer. We organize our article with six critical questions: (1) What are the most important directions of research in this area? (2) Does personal cancer communication work through rational processes, or are affective and nonrational processes also involved? (3) Are our efforts adequate to reach underserved populations? (4) Are naturalistic communicative contexts given adequate consideration? (5) Has the field been adequately informed by social psychological and communication theories? (6) What are the best outcomes to document communication effectiveness? Our goals are to initiate thought and collaborative efforts among communication, public health, and behavioral science experts, as well as to establish research priorities at the interface of communication and cancer prevention and control sciences.

A systematic review of decision support needs of parents making child health decisions

OBJECTIVE

To identify the decision support needs of parents attempting to make an informed health decision on behalf of a child.

CONTEXT

The first step towards implementing patient decision support is to assess patients' information and decision-making needs.

SEARCH STRATEGY

A systematic search of key bibliographic databases for decision support studies was performed in 2005. Reference lists of relevant review articles and key authors were searched. Three relevant journals were hand searched.

INCLUSION CRITERIA

Non-intervention studies containing data on decision support needs of parents making child health decisions.

DATA EXTRACTION AND SYNTHESIS

Data were extracted on study characteristics, decision focus and decision support needs. Studies were quality assessed using a pre-defined set of criteria. Data synthesis used the UK Evidence for Policy and Practice Information and Co-ordinating Centre approach.

MAIN RESULTS

One-hundred and forty nine studies were included across various child health decisions, settings and study designs. Thematic analysis of decision support needs indicated three key issues: (i) information (including suggestions about the content, delivery, source, timing); (ii) talking to others (including concerns about pressure from others); and (iii) feeling a sense of control over the process that could be influenced by emotionally charged decisions, the consultation process, and structural or service barriers. These were consistent across decision type, study design and whether or not the study focused on informed decision making.

The impact of individualised cardiovascular disease (CVD) risk estimates and lifestyle advice on physical activity in individuals at high risk of CVD: a pilot 2 x 2 factorial understanding risk trial

Background

There is currently much interest in encouraging individuals to increase physical activity in order to reduce CVD risk. This study has been designed to determine if personalised CVD risk appreciation can increase physical activity in adults at high risk of CVD.

Methods/Design

In a 2 × 2 factorial design participants are allocated at random to a personalised 10-year CVD risk estimate or numerical CVD risk factor values (systolic blood pressure, LDL cholesterol and fasting glucose) and, simultaneously, to receive a brief lifestyle advice intervention targeting physical activity, diet and smoking cessation or not. We aim to recruit 200 participants from Oxfordshire primary care practices. Eligibility criteria include adults age 40–70 years, estimated 10-year CVD risk ≥20%, ability to read and write English, no known CVD and no physical disability or other condition reducing the ability to walk. Primary outcome is physical activity measured by ActiGraph accelerometer with biochemical, anthropometrical and psychological measures as additional outcomes. Primary analysis is between group physical activity differences at one month powered to detect a difference of 30,000 total counts per day of physical activity between the groups. Additional analyses will seek to further elucidate the relationship between the provision of risk information, and intention to change behaviour and to determine the impact of both interventions on clinical and anthropometrical measures including fasting and 2 hour plasma glucose, fructosamine, serum cotinine, plasma vitamin C, body fat percentage and blood pressure.

Discussion

This is a pilot trial seeking to demonstrate in a real world setting, proof of principal that provision of personalised risk information can contribute to behaviour changes aimed at reducing CVD risk. This study will increase our understanding of the links between the provision of risk information and behaviour change and if successful, could be used in clinical practice with little or no modification.

Visualizing seismic risk and uncertainty: a review of related research

Government agencies and other authorities often communicate earthquake risks using maps derived from geographic information systems. Yet, little is known about the effects of these maps on risk perceptions. While mental models research and other approaches are available to inform risk communication text design, similar empirically derived guidance is lacking for visual risk communications, such as maps, which are likely to trump text in their impact and appeal. This paper reviews the empirical research that might inform such guidance. Research on graphs, spatial and visual perception, and map design suggests that graphics increase risk avoidance over numerical risk representations, and countable visuals, like dots, can increase the accuracy of perceived risks, but not always. Cartographic design features, such as color, animation, interactivity, and depth cues, are all candidates to represent risk and uncertainty and to influence risk perception. While there are robust known effects of color (e.g., red = danger), with some cultural variability, animation can increase the salience of otherwise obscure features but is not uniformly effective. Depth cues, dimensionality, and the extent to which a representation depicts versus symbolizes a scene will influence the viewer's perspective and perception, depending on the viewer's familiarity with the scene; their effects on risk perception remain unclear. The translation and representation of technical information about risk and uncertainty is critical to risk communication effectiveness. Our review suggests a handful of candidate criteria for evaluating the effects of risk visualizations, short of changes in behavior: accuracy, accessibility, retention, and perceived risk and usefulness.

The impact of different time frames of risk communication on Type 2 diabetes patients' understanding and memory for risk of coronary heart disease and stroke

AIMS

We examined the impact of communicating risk of coronary heart disease (CHD) and stroke, using three time frames (1, 5 or 10 years), on Type 2 diabetic (T2D) patients' understanding of risk of CHD/stroke and their memory for these risks.

METHODS

Patients (N = 95) estimated their risk of developing CHD/having a stroke as a result of diabetes, in one of three time frames. Using the United Kingdom Prospective Diabetes Study Risk Engine and the same time frame, patients were then given individualized, objective risk estimates of developing CHD/stroke. Following explanation of these risks, patients' risk understanding was examined by asking them to report again their risk of developing CHD/stroke. Six weeks later we assessed patient memory for these risks by asking them to recall their actual risk estimates for CHD/stroke.

RESULTS

In all time frames, we successfully reduced participants' originally inflated risk perceptions of CHD (F(1,92) = 73.01, P < 0.001) and stroke (F(1,91) = 119.05, P < 0.001), although the 10-year risk group was the most resistant to correction for both CHD (F(1,90) = 9.32, P < 0.001) and stroke (F(2,88) = 3.97, P < 0.02). Participants' recall of their stroke risk at 6 weeks regressed towards original, inflated risk perceptions for the 10-year group only (F(4,176) = 4.73, P < 0.001).

CONCLUSION

Patients' inflated perceptions of CHD/stroke risk can be easily corrected using shorter (1- or 5-year) risk communication time frames.

Audio-visual presentation of information for informed consent for participation in clinical trials

BACKGROUND

Informed consent is a critical component of clinical research. Different methods of presenting information to potential participants of clinical trials may improve the informed consent process. Audio-visual interventions (presented for example on the Internet, DVD, or video cassette) are one such method.

OBJECTIVES

To assess the effects of providing audio-visual information alone, or in conjunction with standard forms of information provision, to potential clinical trial participants in the informed consent process, in terms of their satisfaction, understanding and recall of information about the study, level of anxiety and their decision whether or not to participate.

SEARCH STRATEGY

We searched: the Cochrane Consumers and Communication Review Group Specialised Register (searched 20 June 2006); the Cochrane Central Register of Controlled Trials (CENTRAL), The Cochrane Library, issue 2, 2006; MEDLINE (Ovid) (1966 to June week 1 2006); EMBASE (Ovid) (1988 to 2006 week 24); and other databases. We also searched reference lists of included studies and relevant review articles, and contacted study authors and experts. There were no language restrictions.

SELECTION CRITERIA

Randomised and quasi-randomised controlled trials comparing audio-visual information alone, or in conjunction with standard forms of information provision (such as written or oral information as usually employed in the particular service setting), with standard forms of information provision alone, in the informed consent process for clinical trials. Trials involved individuals or their guardians asked to participate in a real (not hypothetical) clinical study.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed studies for inclusion and extracted data. Due to heterogeneity no meta-analysis was possible; we present the findings in a narrative review.

MAIN RESULTS

We included 4 trials involving data from 511 people. Studies were set in the USA and Canada. Three were randomised controlled trials (RCTs) and the fourth a quasi-randomised trial. Their quality was mixed and results should be interpreted with caution. Considerable uncertainty remains about the effects of audio-visual interventions, compared with standard forms of information provision (such as written or oral information normally used in the particular setting), for use in the process of obtaining informed consent for clinical trials. Audio-visual interventions did not consistently increase participants' levels of knowledge/understanding (assessed in four studies), although one study showed better retention of knowledge amongst intervention recipients. An audio-visual intervention may transiently increase people's willingness to participate in trials (one study), but this was not sustained at two to four weeks post-intervention. Perceived worth of the trial did not appear to be influenced by an audio-visual intervention (one study), but another study suggested that the quality of information disclosed may be enhanced by an audio-visual intervention. Many relevant outcomes including harms were not measured. The heterogeneity in results may reflect the differences in intervention design, content and delivery, the populations studied and the diverse methods of outcome assessment in included studies.

AUTHORS' CONCLUSIONS

The value of audio-visual interventions for people considering participating in clinical trials remains unclear. Evidence is mixed as to whether audio-visual interventions enhance people's knowledge of the trial they are considering entering, and/or the health condition the trial is designed to address; one study showed improved retention of knowledge amongst intervention recipients. The intervention may also have small positive effects on the quality of information disclosed, and may increase willingness to participate in the short-term; however the evidence is weak. There were no data for several primary outcomes, including harms. In the absence of clear results, triallists should continue to explore innovative methods of providing information to potential trial participants. Further research should take the form of high-quality randomised controlled trials, with clear reporting of methods. Studies should conduct content assessment of audio-visual and other innovative interventions for people of differing levels of understanding and education; also for different age and cultural groups. Researchers should assess systematically the effects of different intervention components and delivery characteristics, and should involve consumers in intervention development. Studies should assess additional outcomes relevant to individuals' decisional capacity, using validated tools, including satisfaction; anxiety; and adherence to the subsequent trial protocol.

Improving patient adherence to lifestyle advice (IMPALA): a cluster-randomised controlled trial on the implementation of a nurse-led intervention for cardiovascular risk management in primary care (protocol)

BACKGROUND

Many patients at high risk of cardiovascular diseases are managed and monitored in general practice. Recommendations for cardiovascular risk management, including lifestyle change, are clearly described in the Dutch national guideline. Although lifestyle interventions, such as advice on diet, physical exercise, smoking and alcohol, have moderate, but potentially relevant effects in these patients, adherence to lifestyle advice in general practice is not optimal. The IMPALA study intends to improve adherence to lifestyle advice by involving patients in decision making on cardiovascular prevention by nurse-led clinics. The aim of this paper is to describe the design and methods of a study to evaluate an intervention aimed at involving patients in cardiovascular risk management.

METHODS

A cluster-randomised controlled trial in 20 general practices, 10 practices in the intervention arm and 10 in the control arm, starting on October 2005. A total of 720 patients without existing cardiovascular diseases but eligible for cardiovascular risk assessment will be recruited. In both arms, the general practitioners and nurses will be trained to apply the national guideline for cardiovascular risk management. Nurses in the intervention arm will receive an extended training in risk assessment, risk communication, the use of a decision aid and adapted motivational interviewing. This communication technique will be used to support the shared decision-making process about risk reduction. The intervention comprises 2 consultations and 1 follow-up telephone call. The nurses in the control arm will give usual care after the risk estimation, according to the national guideline. Primary outcome measures are self-reported adherence to lifestyle advice and drug treatment. Secondary outcome measures are the patients' perception of risk and their motivation to change their behaviour. The measurements will take place at baseline and after 12 and 52 weeks. Clinical endpoints will not be measured, but the absolute 10-year risk of cardiovascular events will be estimated for each patient from medical records at baseline and after 1 year.

DISCUSSION

The combined use of risk communication, a decision aid and motivational interviewing to enhance patient involvement in decision making is an innovative aspect of the intervention.

TRIAL REGISTRATION

Current Controlled Trials ISRCTN51556722.

Communicating study results to our patients: which way is best?

Before we are able to communicate evidence and evidence results to patients we must first be familiar with the common ways by which results may be presented to our patients. We describe five approaches (relative risk, risk reduction, odds ratio, absolute risk difference and number needed to treat) of transforming the results of an orthopaedic study for communication with patients.

Making a bad thing worse: Effects of communication of results of an epidemiological study after an aviation disaster

Cognitions attributing health complaints to disaster exposure are associated with more severe health complaints and are therefore a promising target for interventions. Little is known about the best strategy to modify such cognitions following exposure to a technological disaster at the community level. In 1992, a Boeing 747 crashed in a residential area in Amsterdam, the Netherlands. Persisting rumours about the possible toxic cargo of the plane led to increasing health concerns among the residents and rescue workers involved in the disaster. The current study investigates (a) the effectiveness of providing information on the health consequences of exposure to the aviation disaster to residents and rescue workers with varying degrees of exposure to the disaster, and (b) individual characteristics which may moderate the effectiveness of the health information provided. A total of 1019 rescue workers and 453 residents involved with varying degrees in the disaster participated in an epidemiological investigation and 1736 rescue workers and 339 residents, all involved, participated in an individual medical examination. Participants were assessed at baseline and 6 weeks after communication of the results of the epidemiological study. Main outcome measures evaluated health anxiety, somatic sensitivity, reassurance by a physician, psychopathology, post-traumatic stress symptoms, fatigue and quality of life. All participants reported elevated levels of psychopathology and fatigue, increased anxiety and uncertainties about their health 6 weeks after communication of the study results irrespective of the degree of exposure to the disaster. In particular, the conviction that health complaints were caused by toxic exposure was related to more severe health complaints and worries in both rescue workers and residents. Our study shows that communication about the health consequences of exposure to an aviation disaster at the community level has no symptom reducing or reassuring effects. Tailoring of the communication to individual characteristics such as existing expectancies may enhance its impact.

Characteristics of communication guidelines that facilitate or impede guideline use: a focus group study

Background

The quality of doctor-patient communication has a major impact on the quality of medical care. Communication guidelines define best practices for doctor patient communication and are therefore an important tool for improving communication. However, adherence to communication guidelines remains low, despite doctors participating in intensive communication skill training. Implementation research shows that adherence is higher for guidelines in general that are user centred and feasible, which implies that they are consistent with users' opinions, tap into users' existing skills and fit into existing routines. Developers of communication guidelines seem to have been somewhat negligent with regard to user preferences and guideline feasibility. In order to promote the development of user centred and practicable communication guidelines, we elicited user preferences and identified which guideline characteristics facilitate or impede guideline use.

Methods

Seven focus group interviews were conducted with experienced GPs, communication trainers (GPs and behavioural scientists) and communication learners (GP trainees and medical students) and three focus group interviews with groups of GP trainees only. All interviews were transcribed and analysed qualitatively.

Results

The participants identified more impeding guideline characteristics than facilitating ones. The most important impeding characteristic was that guidelines do not easily fit into GPs' day-to-day practice. This is due to rigidity and inefficiency of communication guidelines and erroneous assumptions underpinning guideline development. The most important facilitating characteristic was guideline structure. Guidelines that were structured in distinct phases helped users to remain in control of consultations, which was especially useful in complicated consultations.

Conclusion

Although communication guidelines are generally considered useful, especially for structuring consultations, their usefulness is impaired by lack of flexibility and applicability to practice routines. User centred and feasible guidelines should combine the advantages of helping doctors to structure consultations with flexibility to tailor communication strategies to specific contexts and situations.

Duration of an Intervention's Impact on Perceived Breast Cancer Risk

This study explored risk perceptions after breast cancer risk appraisal. The study involved a randomized trial of Women's Health clinic patients (≥ 40 years old). Primary outcome was perceived breast cancer risk at baseline, 1 month, 6 months, and 18 months. Perceived breast cancer risks were higher than actual calculated risks at baseline. At baseline, 45% reported moderate/strong risk and 43% reported lower-than-average risk; 53% said that their risk was lower than 15%. Mean perceived lifetime risk was 31 out of 100. Throughout follow-up, the treatment group reported lower risks by all measures, as compared to controls. However, for African American women, perceived risk “out of 100 women” did not change. A brief health risk appraisal tends to lower breast cancer risk perceptions for at least 18 months, but the impact may vary by race/ethnicity. These findings could affect health behaviors, such as annual mammograms, which are influenced by perceived risk.
