Numeracy and Health Numeracy Among Chinese and Kenyan Immigrants to Canada

Mathematics self-efficacy plays an important role in the performance of quantitative tasks. The objective of this study was to examine the role of mathematics self-efficacy in numeracy and health numeracy among immigrants (60 Mandarin-speaking and 60 Kikuyu-speaking immigrants to Canada) for whom English was a second language (ESL). Two French Kit numeracy tasks (the addition, and the addition and subtraction correction tasks) constituted objective measures of numeracy, and the numeracy component of a health literacy instrument (The Short Test of Functional Health Literacy for Adults [S-TOFHLA]) constituted the health numeracy measure. We measured math self-efficacy using the Mathematics Self-Efficacy Scale (MSES) and the Subjective Numeracy Scale (SNS). All measures were presented in English. Kikuyu speakers had lower math self-efficacy ( p < .05) compared with Mandarin speakers ( p < .05). Mandarin speakers outperformed Kikuyu speakers in numeracy ( p < .001) and health numeracy ( p < .023) skills. In multiple regression analyses, 32% to 57 % of the variance in objective numeracy was explained by language, residency in Canada, and self-efficacy, adjusting for the other predictor variables; self-efficacy and format of numeric health information (numbers only vs. numbers with detailed text) consistently predicted health numeracy. Mathematics self-efficacy may be an important factor in numeracy, but not as important in health numeracy for Kikuyu- and Mandarin-speaking immigrants for whom English is a second language. Factors contributing to low numeracy may differ from those explaining low health numeracy in ESL immigrants.
