Assessing health numeracy among community-dwelling older adults.
ABSTRACT Quantitative information occupies a central role within health care decision making. Despite this, numeracy has attracted little research attention. Therefore, the purpose of this study was to (1) describe the health numeracy skill of a nonclinical, Canadian community-based senior population and (2) determine the relationship between health numeracy skill and prose health literacy, education, and math anxiety in this population. A convenience sample of 140 men and women, 50 + years, completed a questionnaire assessing demographic details, math anxiety, functional health literacy (Shortened Test of Functional Health Literacy for Adults STOFHLA), general context numeracy, and health context numeracy skills. Most participants had adequate functional health literacy (prose and numeracy) as measured by the STOFHLA, poorer general context numeracy skill, higher health context numeracy skill, and moderate math anxiety. Approximately 36% of the variation in general context numeracy scores and 26% of the variation in health context numeracy scores were explained by prose health literacy skill (STOFHLA), math anxiety, and attained education. This research offers an initial assessment of health numeracy skills as measured by three existing numeracy scales among a group of independently functioning older Canadian adults. This work highlights the need for clarification of the numeracy concept and refinement of health numeracy assessment instruments. Moreover, identifying patients' numeracy strengths and weaknesses will enable the development of focused numeracy interventions and may contribute to moving individuals further along the continuum of health literacy proficiency.

ABSTRACT: In developing countries, education levels vary dramatically, and the number of years of schooling does not always correlate with the true level of educational competency. This study was designed to verify the accuracy of the Short-Test of Functional Health Literacy in Adults (S-TOFHLA) in individuals with mild cognitive impairment (MCI) and mild Alzheimer's disease (AD), when compared with healthy controls (HCs), in order to assess its utility as a measure of functional literacy. One hundred forty-eight subjects were divided into three groups: HC (n = 61), MCI patients (n = 42), and AD patients (n = 45). The S-TOFHLA does not seem to be suitable as an instrument to measure functional literacy for patients with advanced cognitive impairment, but proved to be appropriate in both the HC group and MCI patients in numeracy and prove to be useful as an adjuvant to estimate IQ, reading ability, and premorbid IQ, as an indicator of cognitive reserve.Archives of Clinical Neuropsychology 02/2014; DOI:10.1093/arclin/act120 · 1.92 Impact Factor
Conference Paper: An Adaptive Testing Model for Assessment of Numeracy in Patients[Show abstract] [Hide abstract]
ABSTRACT: Numeracy in healthcare domain is a measure of the ability of patients to understand and digest numerically presented information so as to make appropriate health decisions and understand the underlying risk factors. The existing methods of numeracy testing do not take confidence as a parameter in consideration for adaptive assessment. Numeracy assessment without confidence is prone to guess work. A better result in measurement is achieved when confidence in the knowledge is also appraised. More importantly, patients may act up on their knowledge when they have confidence in it. Thus we aim to develop a new model and based on it a Patient Numeracy Assessment (PNA) tool.2014 IEEE 27th International Symposium on Computer-Based Medical Systems (CBMS); 05/2014

ABSTRACT: Patient portals, which allow patients to access their health record via the Internet, are becoming increasingly widespread and are expected to be used by diverse consumer populations. In addition to technology skills, numeracy skills are also likely to be critical to performing health management tasks, as much of the data contained in the portal are numeric. This study examined how factors such as Internet experience, numeracy, and education impacted the performance of common tasks using a simulated patient portal among a sample of older adults. In addition, information was gathered on the ability of older adults to estimate their numeracy skills. Results indicated that numeracy and Internet experience had a significant impact on their ability to perform the tasks and that older adults tended to overestimate their numeracy skills. Results from this study can help to identify interventions that may enhance the usability of patient portals for older adults.06/2014; 33(4):416-436. DOI:10.1177/0733464812447283
