Background. Numeracy, how facile people are with basic probability and mathematical concepts, is associated with how people perceive health risks. Performance on simple numeracy problems has been poor among populations with little as well as more formal education. Here, we examine how highly educated participants performed on a general and an expanded numeracy scale. The latter was designed within the context of health risks. Method. A total of 463 men and women aged 40 and older completed a 3…

Measuring Numeracy without a Math Test: Development of the Subjective Numeracy Scale

TLDR
The Subjective Numeracy Scale (SNS), an 8-item measure, correlates well with mathematical test measures of objective numeracy but can be administered in less time and with less burden, and shows much lower rates of missing or incomplete data.

Health Numeracy

TLDR
The results suggest that health numeracy is strongly related to general numeracy but that the 2 constructs may not be the same, and further research is needed into how different aspects of general numerical ability translate into actual medical decisions.

Health numeracy in Japan: measures of basic numeracy account for framing bias in a highly numerate population

TLDR
Despite relatively high levels of health numeracy according to these scales, numeracy measures are still important determinants underlying susceptibility to framing bias and it is important in Japan to identify individuals with low numeracy skills so that risk information can be presented in a way that enables them to correctly understand it.

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

TLDR
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.

Subjective Numeracy Scale as a Tool for Assessing Statistical Numeracy in Older Adult Populations

TLDR
The subjective numeracy scale provides an effective tool for assessing statistical numeracy for broad age ranges and circumvents problems associated with objective numeracy measures.

Lower objectively and subjectively assessed numeracy are both associated with poorer self-rated health

TLDR
Lower numeracy, whether subjectively or objectively assessed, was associated with worse self-reported health, even after controlling for education and other sociodemographic confounders.

Development and Testing of an Abbreviated Numeracy Scale: A Rasch Analysis Approach

TLDR
A shorter, psychometrically improved measure of numeracy—the ability to understand, manipulate, and use numerical information, including probabilities, is developed, which is the first to present the psychometric properties of several popular numeracy measures across a diverse sample of ages and educational level.

TLDR
The Numeracy Understanding in Medicine Instrument can be applied in research and clinical settings as a robust measure of the health numeracy construct and was found to be most discriminating among respondents with a lower-than-average level ofhealth numeracy.

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

Validation of the Subjective Numeracy Scale: Effects of Low Numeracy on Comprehension of Risk Communications and Utility Elicitations

TLDR
The Subjective Numeracy Scale effectively predicts both risk comprehension and completion of utility elicitations without requiring survey participants to complete time-consuming and stress-inducing mathematics tests.

Assessing Values for Current Health: Numeracy Matters

TLDR
Limited numeracy may be an important barrier to meaningfully assessing patients values using the standard gamble and time tradeoff and investigators assessing patientsvalues should consider restricting their use of these methods to subjects with high levels of numeracy or use a visual analogue scale.

Patients' understanding of medical risks: implications for genetic counseling.

Health literacy among Medicare enrollees in a managed care organization.

TLDR
Elderly managed care enrollees may not have the literacy skills necessary to function adequately in the health care environment, and low health literacy may impair elderly patients' understanding of health messages and limit their ability to care for their medical problems.

The Role of Numeracy in Understanding the Benefit of Screening Mammography

TLDR
The goal was to understand how numeracy affects women's ability to gauge the benefit of mammography after receiving quantitative information, and to hypothesized that the ability to use quantitative risk information would be related to the level of numeracy.

Testing different formats for communicating colorectal cancer risk.

TLDR
Independent of experimental condition, participants tended to increase their intentions to get screened for CRC in the next year or two, and intention to be screened was more pronounced among participants who had been screened via a fecal occult blood test or sigmoidoscopy.

How to Improve Bayesian Reasoning Without Instruction: Frequency Formats

TLDR
By analyzing several thousand solutions to Bayesian problems, the authors found that when information was presented in frequency formats, statistically naive participants derived up to 50% of all inferences by Bayesian algorithms.

How can we help people make sense of medical data?

TLDR
This tutorial aims to improve critical reading skills by teaching people about risk and showing them what to look for in statements about risk, and how to put disease risk and treatment benefit in context.

Factor analytic approaches to personality item-level data.

TLDR
Recent developments in factor analysis that are appropriate for the type of item-level data often collected in personality are reviewed, and the relevance of item scaling is discussed in the context of these models.
