A few recent studies have found numeracy to be important in health (11); and while health literacy and numeracy may be related (10), we have found many patients with adequate health literacy skills who lack basic numeracy skills (9).
However, most previous studies have been targeted at students' medication calculation and numeracy skills, although calculation errors are only one factor contributing to medication errors [ 12].
"International studies have shown that over the past two decades, Australia's literacy and numeracy skill levels have stagnated while those of other countries, particularly in the Asia-Pacific region, have improved".
Overall, participants in this study had lower numeracy as compared to general HL skills as measured by the NVS and SAHL, respectfully.
Participatory design process that has been conducted with children with autism earlier in the study has led towards the invention of touchscreen-assistive learning numeracy apps (TaLNA).
This study has also shown that by accessing publicly-available literacy and numeracy results (for example, NAPLAN data in Australia) the outcome - "academic achievement" – can be easily ascertained for whole communities of children.
The strength of evidence of numeracy studies was insufficient to low, limiting conclusions about the influence of numeracy on health care service use or health outcomes.
To date, these scales are among the most frequently used instruments in numeracy studies.
Previous studies assessing health numeracy have shown that individuals with low numeracy are more likely to misunderstand risk information, and their risk evaluations tend to be more influenced by context, such as how the related numbers are framed (reviewed in [ 5, 8- 11]).
In addition, numeracy could have affected understanding but was not addressed in this study and may have provided further insight into the study findings.
