Sex Moderates the Relationship Between Social Support and Cardiovascular Prevention Behaviors in Middle-aged and Older Adults.

BACKGROUND: Most risk factors for cardiovascular disease (CVD) are modifiable, suggesting that the burden of CVD could be substantially reduced through cardiovascular screening and healthier lifestyle. People who have social support are more likely to adhere to cardiovascular prevention recommendations, but it is not clear whether the benefit of social support is equal for men and women. PURPOSE: We investigated whether sex moderates the relationship between social support and adherence to cardiovascular prevention recommendations in a nationally representative sample. METHODS: Participants were 17,287 adults (n = 10,264 middle-aged adults 40-64 years old and n = 7,023 older adults ≥ 65 years old) who participated in the National Health Survey of Spain in 2017. Social support was measured with the Functional Social Support Questionnaire of Duke-UNC. Adherence to cardiovascular screening recommendations was assessed based on self-reported testing of cholesterol, blood pressure, and blood sugar by a health professional in the past 12 months. Adherence to recommended health-related behaviors was assessed based on the guidelines of the European Society of Cardiology regarding diet, alcohol consumption, smoking, and physical activity. RESULTS: Multiple regression models adjusted for socio-demographic and cardiovascular history and risk variables showed that social support was more strongly associated with adherence to cardiovascular prevention recommendations in men than in women. In particular, low social support levels were especially detrimental for both middle-aged men (screening: B = 0.13, 95% CI [0.06-0.20], p < .001; behaviors: B = 0.33 [0.26-0.41], p < .001) and older men (screening: B = 0.10 [0.04-0.17], p = .001; behaviors: B = 0.16 [0.08-0.25], p < .001), whereas older women had comparatively high adherence, which was unrelated to social support (screening: B = 0.02 [-0.03 to 0.08], p = .433; behaviors: B = 0.03 [-0.03 to 0.10], p = .342). CONCLUSIONS: Social support is more strongly associated with cardiovascular prevention in men than in women, such that men who lack social support have the lowest adherence to cardiovascular screening and lifestyle recommendations.

To help prevent cardiovascular disease, experts recommend screening for cardiovascular risk factors and leading a healthy lifestyle. Previous research has found that people who have social support are more likely to adhere to such cardiovascular prevention recommendations. In this study, using data form a nationally representative survey, we investigated whether the relationship between social support and adherence to cardiovascular prevention recommendations is different for men and women. Participants were 17,287 adults from the National Health Survey of Spain, who reported their cardiovascular screening history (i.e., whether they had their cholesterol, blood pressure, and blood sugar levels tested by a health professional in the past 12 months) and their lifestyle habits regarding diet, alcohol consumption, smoking, and physical activity. Social support was more strongly associated with cardiovascular prevention in men than in women, such that men who lacked social support had the lowest adherence to cardiovascular screening and lifestyle recommendations.

Cancer awareness in older adults: Results from the Spanish Onco-barometer cross-sectional survey.

BACKGROUND: About half of all cancers are diagnosed in adults older than 65, making them the age group at highest risk of developing this disease. Nurses from different specialties can support individuals and communities in the prevention and early detection of cancer and should be aware of the common knowledge gaps and perceived barriers among older adults. OBJECTIVES: The goal of the current research was to investigate personal characteristics, perceived barriers, and beliefs related to cancer awareness in older adults, with a special focus on perceptions about the influence of cancer risk factors, knowledge of cancer symptoms, and anticipated help-seeking. DESIGN: Descriptive cross-sectional study. PARTICIPANTS: Participants were 1213 older adults (≥65 years old) from the representative national Onco-barometer survey conducted in 2020 in Spain. METHODS: Questions on the perceived influence of cancer risk factors, knowledge of cancer symptoms, and the Spanish version of the Awareness and Beliefs about Cancer (ABC) questionnaire were administered in computer-assisted telephone interviews. RESULTS: Knowledge of cancer risk factors and symptoms was strongly related to personal characteristics and was limited among males and older individuals. Respondents from lower socio-economic background recognized fewer cancer symptoms. Having personal or family history of cancer had opposite effects on cancer awareness: It was related to more accurate symptom knowledge but also to lower perceptions about the influence of risk factors and more delayed help-seeking. Anticipated help-seeking times were strongly influenced by perceived barriers to help-seeking and beliefs about cancer. Worry about wasting the doctor's time (48% increase, 95% CI [25%-75%]), about what the doctor might find (21% increase [3%-43%]) and not having enough time to go to the doctor (30% increase [5%-60%]) were related to more delayed help-seeking intentions. In contrast, beliefs that reflected higher perceived seriousness of a potential cancer diagnosis were related to shorter anticipated help-seeking times (19% decrease [5%-33%]). CONCLUSIONS: These results suggest that older adults could benefit from interventions informing them about how to reduce their cancer risk and addressing emotional barriers and beliefs associated with help-seeking delays. Nurses can contribute to educating this vulnerable group and are in a unique position to address some barriers to help-seeking. STUDY REGISTRATION: Not registered.

Allostatic Load and Depression Symptoms in Cancer Survivors: A National Health and Nutrition Examination Survey Study.

BACKGROUND: Individuals with cancer often experience stress throughout the cancer trajectory and have a high risk of experiencing depression. OBJECTIVE: The aim of this study was to examine the relationship between allostatic load (AL), a measure of cumulative stress-related physiologic dysregulation of different body systems, and symptoms of depression in cancer survivors. METHODS: Participants were 294 adult cancer survivors from the US National Health and Nutrition Examination Survey (NHANES 2007-2018). Allostatic load was measured using 14 indicators representing cardiometabolic risk, glucose metabolism, cardiopulmonary functioning, parasympathetic functioning, and inflammation. Depressive symptoms were measured with the Patient Health Questionnaire-9. The relationship between AL and depressive symptoms was investigated using multiple regression adjusted for diverse sociodemographic and diagnosis variables. RESULTS: Higher AL was associated with higher depressive symptom scores. The higher risk of depression was concentrated among those survivors in the highest AL quartile, with 21% (95% confidence interval, 11%-32%) of survivors presenting a high risk of depression compared with 8% to 11% of survivors in the lower quartiles. In exploratory analyses, the relationship between AL and depressive symptoms was only significant among survivors with a lower income. In contrast, in survivors in the highest income group, depressive symptoms were lower and unrelated to AL. CONCLUSION: High AL is associated with more depressive symptoms among cancer survivors. IMPLICATIONS FOR PRACTICE: Nurses have an important role in identifying psychological distress in cancer patients and survivors. Further research is needed to investigate the usefulness of AL as a marker in the context of cancer follow-up care and screening for psychological distress.

Measuring feelings about choices and risks: The Berlin Emotional Responses to Risk Instrument (BERRI).

We introduce a brief instrument specifically validated for measuring positive and negative feelings about risks-the Berlin Emotional Responses to Risk Instrument (BERRI). Based on seven studies involving diverse adults from three countries (n = 2120), the BERRI was found to robustly estimate anticipatory affective reactions derived from subjective evaluations of positive (i.e., assured, hopeful, and relieved) and negative emotions (i.e., anxious, afraid, and worried). The brief BERRI outperformed a 14-item assessment, uniquely tracking costs/benefits associated with cancer screening among men and women (Studies 1 and 2). Predictive validity was further documented in paradigmatic risky choice studies wherein options varied over probabilities and severities across six contexts (health, social, financial, technological, ethical, and environmental; Study 3). Studies 4-6, conducted during the Ebola epidemic and COVID-19 pandemic, indicated BERRI responses were sensitive to subtle effects caused by emotion-related framing manipulations presented in different cultures and languages (the United States, Spain, and Poland). Study 7 indicated BERRI responses remained stable for 2 weeks. Although the BERRI can provide an estimate of overall affect, choices were generally better explained by the unique influences of positive and negative affect. Overall, results suggest the novel, brief instrument can be an efficient tool for high-stakes research on decision making and risk communication.

Physical Comorbidities and Depression in Recent and Long-Term Adult Cancer Survivors: NHANES 2007-2018.

Many adult cancer patients present one or more physical comorbidities. Besides interfering with treatment and prognosis, physical comorbidities could also increase the already heightened psychological risk of cancer patients. To test this possibility, we investigated the relationship between physical comorbidities with depression symptoms in a sample of 2073 adult cancer survivors drawn from the nationally representative National Health and Nutrition Examination Survey (NHANES) (2007-2018) in the U.S. Based on information regarding 16 chronic conditions, the number of comorbidities diagnosed before and after the cancer diagnosis was calculated. The number of comorbidities present at the moment of cancer diagnosis was significantly related to depression risk in recent but not in long-term survivors. Recent survivors who suffered multimorbidity had 3.48 (95% CI 1.26-9.55) times the odds of reporting significant depressive symptoms up to 5 years after the cancer diagnosis. The effect of comorbidities was strongest among survivors of breast cancer. The comorbidities with strongest influence on depression risk were stroke, kidney disease, hypertension, obesity, asthma, and arthritis. Information about comorbidities is usually readily available and could be useful in streamlining depression screening or targeting prevention efforts in cancer patients and survivors. A multidimensional model of the interaction between cancer and other physical comorbidities on mental health is proposed.

Physical comorbidities as a marker for high risk of psychological distress in cancer patients.

AIMS: Physical and psychiatric comorbidities are common in cancer patients and could impact their treatment and prognosis. However, the evidence base regarding the influence of comorbidities in the management and health service use of patients is still scant. In this research we investigated how physical comorbidities are related to the mental health and help-seeking of cancer patients. METHODS: Data were obtained from the representative National Health Survey of Spain (2017). Participants were respondents who reported a cancer diagnosis (n = 484). These were also matched with controls without cancer history (n = 484) based on age, gender, and region. Four alternative physical comorbidities indices were created based on information regarding 28 chronic conditions. Outcomes of interest were psychological distress and having consulted a mental healthcare professional in the year before the survey. RESULTS: Thirty percent of cancer patients reported significant psychological distress but only 10% had consulted a professional. After adjusting for sociodemographic variables, among cancer patients each additional comorbidity was associated with 9% higher odds of reporting high psychological distress (odds ratio [OR] = 1.09, 95% confidence interval [CI]: 1.01-1.16) and 21% higher odds of having consulted a mental healthcare professional (OR = 1.21, 95% CI: 1.09-1.34). The effects of comorbidities depended on the type of index and were different in controls without cancer history. CONCLUSION: Physical comorbidities in cancer patients are associated with higher risk of psychological distress and higher demand for mental health services. We encourage further research on this issue as it could improve mental health screening and management in oncologic care.

Scientific risk reporting in medical journals can bias expert judgment: Comparing surgeons' risk comprehension across reporting formats.

A recent systematic search of orthopedic surgery literature suggests that scientific risk reporting often deviates from best practices in specific ways (Petrova, Joeris, Sanchez, Salamanca-Fernandez, & Garcia-Retamero, 2018). These deviations could cause dangerous biases in health professionals' risk interpretations and risk communication practices. To investigate potential vulnerabilities, we conducted the first comparative study estimating the effects of common reporting formats on the judgment of experienced orthopedic surgeons during risk evaluations (i.e., interpreting medical research on the risk of suffering postsurgical side effects in patients). Results indicate that highly trained surgeons were often misled and strongly biased by the most commonly used formats identified in the systematic review. In contrast, less common formats following best practice standards (e.g., transparent visual aids) typically reduced or eliminated judgment biases by helping surgeons identify and compare essential information, streamlining deliberation and reducing subjective confusion. Discussion focuses on implications including additional analyses showing that the use of misleading formats in scientific medical literature is frequent, even in recent years, and it is independent of many other factors (e.g., journal impact, study quality). A broad three-category system for characterizing the probable impact of specific risk reporting formats is discussed. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Cancer screening risk literacy of physicians in training: An experimental study.

We investigated what factors may foster or hinder physicians' cancer screening risk literacy-specifically the ability to understand evidence regarding screening effectiveness and make evidence-based recommendations to patients. In an experiment, physicians in training (interns and residents) read statistical information about outcomes from screening for cancer, and had to decide whether to recommend it to a patient. We manipulated the effectiveness of the screening (effective vs. ineffective at reducing mortality) and the demand of the patient to get screened (demand vs. no demand). We assessed participants' comprehension of the presented evidence and recommendation to the patient, as well as a-priori screening beliefs (e.g., that screening is always a good choice), numeracy, science literacy, knowledge of screening statistics, statistical education, and demographics. Stronger positive a-priori screening beliefs, lower knowledge of screening statistics, and lower numeracy were related to worse comprehension of the evidence. Physicians recommended against the ineffective screening but only if they showed good comprehension of the evidence. Physicians' recommendations were further based on the perceived benefits from screening but not on perceived harms, nor the patient's demands. The current study demonstrates that comprehension of cancer screening statistics and the ability to infer the potential benefits for patients are essential for evidence-based recommendations. However, strong beliefs in favor of screening fostered by promotion campaigns may influence how physicians evaluate evidence about specific screenings. Fostering physician numeracy skills could help counteract such biases and provide evidence-based recommendations to patients.

How are risk ratios reported in orthopaedic surgery journals? A descriptive study of formats used to report absolute risks.

PURPOSE: The numerical format in which risks are communicated can affect risk comprehension and perceptions of medical professionals. We investigated what numerical formats are used to report absolute risks in empirical articles, estimated the frequency of biasing formats and rated the quality of figures used to display the risks. DESIGN: Descriptive study of reporting practices. METHOD: We randomly sampled articles published in seven leading orthopaedic surgery journals during a period of 13 years. From these, we selected articles that reported group comparisons on a binary outcome (eg, revision rates in two groups) and recorded the numerical format used to communicate the absolute risks in the results section. The quality of figures was assessed according to published guidelines for transparent visual aids design. OUTCOME MEASURES: Prevalence of information formats and quality of figures. RESULTS: The final sample consisted of 507 articles, of which 14% reported level 1 evidence, 13% level 2 and 73% level 3 or lower. The majority of articles compared groups of different sizes (90%), reported both raw numbers and percentages (64%) and did not report the group sizes alongside (50%). Fifteen per cent of articles used two formats identified as biasing: only raw numbers (8%, '90 patients vs 100 patients') or raw numbers reported alongside different group sizes (7%, '90 out of 340 patients vs 100 out of 490 patients'). The prevalence of these formats decreased in more recent publications. Figures (n=79) had on average two faults that could distort comprehension, and the majority were rated as biasing. CONCLUSION: Authors use a variety of formats to report absolute risks in scientific articles and are likely not aware of how some formats and graph design features can distort comprehension. Biases can be reduced if journals adopt guidelines for transparent risk communication but more research is needed into the effects of different formats.

Strengths and Gaps in Physicians' Risk Communication: A Scenario Study of the Influence of Numeracy on Cancer Screening Communication.

OBJECTIVE: Many patients have low numeracy, which impedes their understanding of important information about health (e.g., benefits and harms of screening). We investigated whether physicians adapt their risk communication to accommodate the needs of patients with low numeracy, and how physicians' own numeracy influences their understanding and communication of screening statistics. METHODS: UK family physicians ( N = 151) read a description of a patient seeking advice on cancer screening. We manipulated the level of numeracy of the patient (low v. high v. unspecified) and measured physicians' risk communication, recommendation to the patient, understanding of screening statistics, and numeracy. RESULTS: Consistent with best practices, family physicians generally preferred to use visual aids rather than numbers when communicating information to a patient with low (v. high) numeracy. A substantial proportion of physicians (44%) offered high quality (i.e., complete and meaningful) risk communication to the patient. This was more often the case for physicians with higher (v. lower) numeracy who were more likely to mention mortality rates, OR=1.43 [1.10, 1.86], and harms from overdiagnosis, OR=1.44 [1.05, 1.98]. Physicians with higher numeracy were also more likely to understand that increased detection or survival rates do not demonstrate screening effectiveness, OR=1.61 [1.26, 2.06]. CONCLUSIONS: Most physicians know how to appropriately tailor risk communication for patients with low numeracy (i.e., with visual aids). However, physicians who themselves have low numeracy are likely to misunderstand the risks and unintentionally mislead patients by communicating incomplete information. High-quality risk communication and shared decision making can depend critically on factors that improve the risk literacy of physicians.

To screen or not to screen: What factors influence complex screening decisions?

Contrary to people's intuitions, many screenings can have both benefits (e.g., lives saved) and harms (e.g., unnecessary treatments). Statistical information is often provided to ensure informed decision making. However, few theoretical models have addressed the role of comprehension of such information in screening decisions. In an experiment, we studied how cognitive skills, emotions, and a priori beliefs about screening affect comprehension of the evidence of benefits and harms from screening and intentions to get screened. Young adults (N = 347) received information about a disease for which a screening test was available and numerical information about the benefits and harms from screening. Results showed that comprehension and perceptions of benefits are central to decisions; however, lay perceptions of harms along the screening cascade require further study. Numeracy, science literacy, and emotions can promote informed decision making by facilitating comprehension of the evidence. At the same time emotions and beliefs resulting from persuasive campaigns can have strong effects on screening intentions beyond the available evidence. To apply to screening procedures where informed decision making is recommended, theoretical models of screening decisions need to include comprehension of benefits and harms, and account for how cognitive skills, emotions, and beliefs influence comprehension and decisions.

Lonely hearts don't get checked: On the role of social support in screening for cardiovascular risk.

OBJECTIVE: Regular cardiovascular risk screening can prevent cardiovascular disease through timely implementation of lifestyle changes or medication. However, few studies have investigated what factors promote regular screening for risk factors like hypertension and high blood cholesterol. The aim of this study was to investigate the relationship between social support and adherence to cardiovascular risk screening. METHODS: We analyzed data from the Spanish National Health Survey-a cross-sectional representative survey conducted by the Spanish Ministry of Health in 2012 (N=21,007). Participants reported whether they had their blood pressure and cholesterol levels measured by a health professional in the previous 12 months. Social support (i.e., the perception that emotional and practical support was available when needed) was measured with a validated scale. Multiple logistic regressions were conducted adjusted for demographic and health-related factors. RESULTS: Compared to individuals who reported a lack of social support, individuals who perceived sufficient social support were on average twice more likely to report participation in blood pressure screening, OR=2.06, 95% CI [1.60, 2.66] and cholesterol screening, OR=2.85, 95% CI [1.99, 4.09]. These effects were uniform across different demographics and were replicated in a previous wave of the survey. Factors associated with worse screening adherence were low social class, being single or widowed, smoking, alcohol consumption, and no history of cardiovascular risk. DISCUSSION: Perceptions of social support are positively related to cardiovascular risk screening adherence. Future research should investigate what type of social support most effectively increases screening participation among high risk populations.

The Views of Young Women on HPV Vaccine Communication in Four European Countries.

The Human Papilloma Virus (HPV) is the most common sexually transmitted infection (STI) and can cause cervical cancer. Two vaccines are available to protect against the most common strands of the virus. Vaccination programs differ across Europe but most neglect young adults, who are the group with the highest risk of contracting STIs. Our aim was to explore the views of young women from four European countries­Scotland, Spain, Serbia, and Bulgaria - about the HPV vaccine communication strategy. These countries are characterized by different cervical cancer prevalence and vaccine implementation policies. We conducted focus group discussions with young women (aged 18-26) with various vaccination histories in a purposive sample. We subjected the data to thematic analysis with the purpose of identifying themes related to communication about the HPV vaccine. We recorded the information sources mentioned by participants. Participants discussed numerous sources of vaccine-related information. They approached information critically rather than naively and questioned the sources' trustworthiness and motives. Participants desired transparent information about the risks of the virus and the risks and benefits of the vaccine. These risks and benefits were individualized in view of personal and external factors. Particular aspects of the vaccine and the way information was communicated resulted in feelings of uncertainty. There were notable cross-cultural differences in experiences with HPV vaccine communication. Our results suggest that transparent risk communication about the HPV vaccine is valued by young women. In addition, both individual and culturally-dependent factors influenced experiences with, and preference for information.

Understanding the Harms and Benefits of Cancer Screening: A Model of Factors That Shape Informed Decision Making.

OBJECTIVE: Decisions about cancer screenings often involve the consideration of complex and counterintuitive evidence. We investigated psychological factors that promote the comprehension of benefits and harms associated with common cancer screenings and their influence on shared decision making. METHODS: In experiment 1, 256 men received information about PSA-based prostate cancer screening. In experiment 2, 355 women received information about mammography-based breast cancer screening. In both studies, information about potential screening outcomes was provided in 1 of 3 formats: text, a fact box, or a visual aid (e.g., mortality with and without screening and rate of overdiagnosis). We modeled the interplay of comprehension, perceived risks and benefits, intention to participate in screening, and desire for shared decision making. RESULTS: Generally, visual aids were the most effective format, increasing comprehension by up to 18%. Improved comprehension was associated with 1) superior decision making (e.g., fewer intentions to participate in screening when it offered no benefit) and 2) more desire to share in decision making. However, comprehension of the evidence had a limited effect on experienced emotions, risk perceptions, and decision making among those participants who felt that the consequences of cancer were extremely severe. CONCLUSIONS: Even when information is counterintuitive and requires the integration of complex harms and benefits, user-friendly risk communications can facilitate comprehension, improve high-stakes decisions, and promote shared decision making. However, previous beliefs about the effectiveness of screening or strong fears about specific cancers may interfere with comprehension and informed decision making.

Habilidades numéricas y salud: una revisión crítica / Numeracy and health: A critical review

A la hora de realizar juicios y tomar decisiones sobre la salud, debemos procesar y comprender información numérica. Por ejemplo, habitualmente recibimos información sobre el riesgo de padecer una enfermedad en probabilidades, porcentajes o fracciones. Sin embargo, muchas personas presentan deficiencias a la hora de comprender esta información. En este trabajo, presentamos una revisión crítica de la evidencia empírica sobre los efectos que tienen las habilidades numéricas en diversos aspectos del proceso que acontece cuando un paciente acude al médico, más concretamente en la percepción de los riesgos médicos y la eficacia de los tratamientos. También describimos los distintos marcos teóricos que pretenden explicar estos efectos y resaltamos algunas de sus limitaciones. Por último, discutimos las ventajas y los inconvenientes de los instrumentos de medida de las habilidades numéricas, y destacamos entre ellos el Berlin Numeracy Test. Concluimos que este test puede evaluar las habilidades numéricas satisfactoriamente en diversos contextos, y planteamos diversas cuestiones que permanecen abiertas, como la relación entre las habilidades numéricas y diversos constructos psicológicos como la inteligencia o la reflexión cognitiva.

When we make judgments and decisions about our health, we are frequently faced with numerical information. For example, we often receive information concerning the risk of suffering an illness in terms of probabilities, percentages or fractions. However, many people have difficulties in understanding this type of information. In this paper, we present a critical review of the existing empirical evidence that documents the influence of numeracy on various aspects of the process that occurs when patients visit their doctor, focusing on perceptions of medical risks and treatment efficacy. We also outline different theoretical frameworks that have attempted to explain the impact of numeracy, highlighting some of their limitations. Finally, we discuss the advantages and disadvantages of existing tools for measuring numeracy, drawing attention to the Berlin Numeracy Test. We concluded that this test can satisfactorily assess numeracy in a wide range of contexts. We also discuss a number of open questions, including the relationship between numeracy and other psychological constructs, such as intelligence or cognitive reflection.

Young women's constructions of the HPV vaccine: a cross-cultural, qualitative study in Scotland, Spain, Serbia and Bulgaria.

BACKGROUND: Following international trends, the HPV (human papilloma virus) vaccine was introduced in Europe for protection against infection from common strands of the HPV virus which can lead to cervical cancer. Young women aged 18-26 years are at greatest risk of infection by the HPV virus yet have been neglected in research, policy, and practice. PURPOSE: To explore young women's constructions of the HPV vaccine in four European countries with different implementation policies ranging from national school-based programmes, regarded as the gold standard, to regional on-demand and private provision. METHOD: Qualitative methods comprising 11 focus group discussions with 54 young women aged 18-26, in Scotland (n = 10), Spain (n = 25), Serbia (n = 9) and Bulgaria (n = 10). A discursive analysis was conducted, following an initial thematic analysis. RESULTS: Two competing discursive constructions were considered: the 'responsible young woman' discourse was constructed as someone with individual rights to health, choice and discretion along with responsibilities to protect health and make rational decisions. In 'the HPV vaccine: a discourse of exclusion', access to the vaccine, wider health promotion and knowledge was controlled by others which had the potential to undermine the young woman's health. We consider how young women managed this tension through recourse to being health vigilant. CONCLUSION: Qualitative, cross-cultural research highlighted common concerns amongst young European women towards being responsible citizens in the face of their health and highlighted socio-cultural constraints to knowledge and resources. We highlight cross-cultural implications particularly between Western and Eastern European contexts.

Cómo Mejorar la Comprensión de los Riesgos Médicos en Personas Mayores / How to Improve Comprehension of Medical Risks in Older Adults

Los mayores con frecuencia toman decisiones sobre su salud. A pesar de ello, prefieren adoptar un rol pasivo en este proceso. Una explicación que se ha ofrecido sobre este hecho es que frecuentemente presentan serias dificultades a la hora de comprender la información que reciben sobre los riesgos médicos. En un estudio, hemos investigado el grado en que los mayores (n=136) comprenden la información sobre la efectividad de los tratamientos médicos. Concretamente, hemos comparado la precisión de las inferencias que éstos realizan con los juicios en adultos jóvenes (n=121). Para ello, hemos presentado la información sobre la efectividad de los tratamientos en formato numérico o visual y hemos clasificado a los participantes según su nivel de habilidades gráficas. Nuestro estudio pone de manifiesto que la precisión de las inferencias que realizan los mayores se incrementa considerablemente cuando la información se representa visualmente. Esto ocurre especialmente cuando presentan habilidades gráficas elevadas. Concluimos que el uso de formatos visuales puede ser un método efectivo, transparente, y fiable de comunicación de la información sobre los riesgos médicos y la salud, y mencionamos las implicaciones prácticas de nuestros resultados para el desarrollo de campañas de salud.

Older adults frequently make decisions about their health. However, they prefer to play a passive role in this process. A plausible explanation of this result is that they often have difficulties understanding information about medical risks. In a study, we investigated the extent to what older adults (n=136) understand information about the effectiveness of medical treatments. In particular, we compared accuracy of their inferences to that of young adults (n=121). Participants were classified according to their graph literacy skills and received information about the effectiveness of medical treatments in a numerical or a visual format. Our study shows that visual aids substantially increased accuracy of inferences in older adults. Older adults with high graph literacy benefit most from the use of visual aids. We conclude that visual aids are often highly effective, transparent, and reliable risk communication tools. We discuss the practical implication of our results for the design of health campaigns.

Do the media provide transparent health information? A cross-cultural comparison of public information about the HPV vaccine.

The media is a powerful tool for informing the public about health treatments. In particular, the Internet has gained importance as a widely valued source for health information for parents and adolescents. Nonetheless, traditional sources, such as newspapers, continue to report on health innovations. But do websites and newspaper reports provide balanced information? We performed a systematic media analysis to evaluate and compare media coverage of the human papillomavirus (HPV) vaccine on websites and in newspapers in Germany and Spain. We assessed to what extent the media provide complete (pros and cons), transparent (absolute instead of relative numbers), and correct information about the epidemiology and etiology of cervical cancer as well as the effectiveness and costs of the HPV vaccine. As a basis for comparison, a facts box containing current scientific evidence about cervical cancer and the HPV vaccine was developed. The media analysis included 61 websites and 141 newspaper articles in Germany, and 41 websites and 293 newspaper articles in Spain. Results show that 57% of German websites and 43% of German newspaper reports communicated correct estimates of epidemiological data, whereas in Spain 39% of the websites and 20% of the newspaper did so. While two thirds of Spanish websites explicitly mentioned causes of cervical cancer as well as spontaneous recovery, German websites communicated etiological information less frequently. Findings reveal that correct estimates about the vaccine's effectiveness were mentioned in 10% of German websites and 6% of German newspaper reports; none of the Spanish newspaper reports and 2% of Spanish websites reported effectiveness correctly. Only German websites (13%) explicitly referred to scientific uncertainty regarding the vaccine's evaluation. We conclude that the media lack balanced reporting on the dimensions completeness, transparency, and correctness. We propose standards for more balanced reporting on websites and in newspapers.

Using plausible group sizes to communicate information about medical risks.

OBJECTIVE: To make informed health decisions, patients must understand and recall risks, which often involve ratios with large denominators. Grasping the meaning of such numbers may be difficult, because of limited exposure to large groups of people in either our evolutionary history or daily life. METHODS: In an experiment (n=98), we investigated whether medical risks are easier to understand and recall if their representation is based on small, evolutionarily plausible groups of people, and whether this representation especially helps patients with low numeracy. RESULTS: Participants-especially those with low numeracy-often disregarded and incorrectly recalled denominators of ratios representing medical risks when the denominators involved were large. Risks were easier to understand and recall if their representation was based on smaller, evolutionarily plausible groups of people. CONCLUSIONS: Our results extend previous literature on the role of numeracy in understanding health-relevant risk communications by showing the importance of using plausible group sizes to communicate these risks to people with low numeracy. Our results also support the notion that problems in risk perception occur because of inappropriate presentation formats rather than cognitive biases. PRACTICE IMPLICATIONS: Our findings suggest suitable ways to communicate quantitative medical data-especially to people with low numeracy.

How to reduce the effect of framing on messages about health.

BACKGROUND: Patients must be informed about risks before any treatment can be implemented. Yet serious problems in communicating these risks occur because of framing effects. OBJECTIVE: To investigate the effects of different information frames when communicating health risks to people with high and low numeracy and determine whether these effects can be countered or eliminated by using different types of visual displays (i.e., icon arrays, horizontal bars, vertical bars, or pies). DESIGN: Experiment on probabilistic, nationally representative US (n = 492) and German (n = 495) samples, conducted in summer 2008. OUTCOME MEASURES: Participants' risk perceptions of the medical risk expressed in positive (i.e., chances of surviving after surgery) and negative (i.e., chances of dying after surgery) terms. KEY RESULTS: Although low-numeracy people are more susceptible to framing than those with high numeracy, use of visual aids is an effective method to eliminate its effects. However, not all visual aids were equally effective: pie charts and vertical and horizontal bars almost completely removed the effect of framing. Icon arrays, however, led to a smaller decrease in the framing effect. CONCLUSIONS: Difficulties with understanding numerical information often do not reside in the mind, but in the representation of the problem.
