We review the growing literature on health numeracy, the ability to understand and use numerical information, and its relation to cognition, health behaviors, and medical outcomes. Despite the surfeit of health information from commercial and noncommercial sources, national and international surveys show that many people lack basic numerical skills that are essential to maintain their health and make informed medical decisions. Low numeracy distorts perceptions of risks and benefits of…

Numeracy and the Motivational Mind: The Power of Numeric Self-efficacy.

A novel modification to dual-process theory is proposed, adding a "motivational mind" to integrate the effects of numeric self-efficacy on decision-making processes (i.e., inferences from experienced difficulty with numbers, greater persistence, and greater use of objective-numeracy skills) important to high-quality MDM.

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

Results showed that comprehension and perceptions of benefits are central to decisions; however, lay perceptions of harms along the screening cascade require further study.

Health Numeracy and Communicating Risk to Patients: Medical Students’ Risk Literacy and Attitudes toward Statistics

This quantitative, non-experimental, predictive, correlational study explored medical students’ risk literacy and attitudes toward statistics as measured by the Berlin Numeracy Test and a linear combination of the Attitudes Toward Statistics subscales and successful completion of a college level statistics course.

The role of numeracy and intelligence in health-risk estimation and medical data interpretation

Despite ample evidence that numeracy is an important influence on patient understanding and use of health-related information, there is a dearth of studies examining the concept's relationship to

Risk Communication in Health

This chapter discusses how transparent risk communication can contribute to informed patients and how transparency can be achieved, and proposes further research to implement the concepts of transparency in risk communication.

Developing a Health Numeracy Scale to Assess Medical Decision Making Among Older Adults

The Subjective Numeracy Scale was tested in comparison to other numeracy scales, and was found to be highly related to objective numeracy, but evidence is still lacking on whether it is useful in predicting medical decision making.

Should Health Numeracy Be Assessed Objectively or Subjectively?

Comparing numeracy assessments obtained using the subjective numeracy scale (SNS) and 5 objective numeracy scales is conducted to determine the proper use of objective versus subjective numerACY assessments in medical decision-making research.

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

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, is investigated.

Is Patients’ Numeracy Related to Physical and Mental Health?

This research documents for the first time that self-reported numeracy is related to perceptions of health, whereas objective numeracy are related to actual health, laying the groundwork for future research on the effect of numeracy on health outcomes.

How to measure risk comprehension in educated samples

The Berlin Numeracy Test is a psychometrically sound instrument designed to quickly assess statistical numeracy and risk comprehension in educated samples (e.g., college students or medical and



Clinical Implications of Numeracy: Theory and Practice

An overview of research on health numeracy is provided and superior quantitative processing seems to be achieved by focusing on qualitative gist and affective meaning, which has important implications for empowering patients to take advantage of the evidence in evidence-based medicine.

Consumer Competencies and the Use of Comparative Quality Information

The findings indicate that numeracy skill is the strongest predictor of comprehension, followed by health literacy, and that choice is not just about literacy or comprehension, it also has to do with activation.

Numeracy, Ratio Bias, and Denominator Neglect in Judgments of Risk and Probability.

Cancer Risk Elicitation and Communication: Lessons from the Psychology of Risk Perception

Many of the psychological processes that underlie risk perception are reviewed and how these processes lead to deviations are discussed, including difficulties with use of numerical information (innumeracy), cognitive processes (eg, use of time‐saving heuristics), motivational factors, and emotion.

Assessing Values for Health: Numeracy Matters

The validity of standard utility assessments is related to the subject’s facility with numbers, and limited numeracy may be an important barrier to meaningfully assessing patients’ values using the standard gamble and time trade-off techniques.

Numeracy skill and the communication, comprehension, and use of risk-benefit information.

This work reviews the literature and examines what can be done to help less numerate people act more effectively and take charge of their health.

Review Paper: Rethinking Health Numeracy: A Multidisciplinary Literature Review

It is argued that essential ingredients for the productive use of quantitative health information include not only health numeracy but also good provider communication skills, as well as documents and devices that are designed to enhance comprehension and cognition.

The Effectiveness of a Primer to Help People Understand Risk

A primer is developed to help people develop the basic skills needed to make sense of the medical risk data that surround them and would improve patients' abilities to interpret medical data.

Numeracy and the medical student's ability to interpret data.

Almost one quarter of first-year medical students in this study had trouble performing basic numerical tasks, and those who had trouble also seemed to have difficulty interpreting medical data.
