Background. Basic numeracy skills are necessary before patients can understand the risks of medical treatments. Previous research has used objective measures, similar to mathematics tests, to evaluate numeracy. Objectives. To design a subjective measure (i.e., self-assessment) of quantitative ability that distinguishes low- and high-numerate individuals yet is less aversive, quicker to administer, and more useable for telephone and Internet surveys than existing numeracy measures.

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

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.

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.

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.

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

Understanding Health Risk Comprehension: The Role of Math Anxiety, Subjective Numeracy, and Objective Numeracy

Math anxiety, objective numeracy, and subjective numeracy are associated with risk comprehension through unique pathways, and education initiatives for improving health risk comprehension may be most effective if jointly aimed at tackling numerical ability as well as negative emotions and self-evaluations related to numeracy.

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

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

Measuring risk literacy: The Berlin numeracy test

We introduce the Berlin Numeracy Test, a new psychometrically sound instrument that quickly assesses statistical numeracy and risk literacy. We present 21 studies (n=5336) showing robust psychometric

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.

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

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

The results suggest that even highly educated participants have difficulty with relatively simple numeracy questions, thus replicating in part earlier studies that usual strategies for communicating numerical risk may be flawed.

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.
