Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? In multivariable analyses, the association between health literacy and task performance was substantially reduced once fluid and crystallized cognitive abilities were entered into models (β = −28.9, 95% CI −31.4 to −26.4 without cognitive abilities; β = −8.5, 95% CI −10.9 to −6.0 with cognitive abilities). → Wolf 2012

q3 · i? · associational · r3
Multivariable regression analysis in the LitCog study (n = 882) showing the health literacy coefficient for task performance dropped from "β = −28.9" to "β = −8.5" after entering fluid and crystallized cognitive abilities. No standardized effect size is printed for the reduction itself.
"In multivariable analyses, the association between health literacy and task performance was substantially reduced once fluid and crystallized cognitive abilities were entered into models (without cognitive abilities: β = −28.9, 95 % Confidence Interval (CI) -31.4 to −26.4, p; with cognitive abilities: β = −8.5, 95 % CI −10.9 to −6.0)."
Discussion¶
Learner Variables¶
- Academic and Critical Literacy — predictor: learners who differ on it differ in outcomes
- General Cognitive Ability — predictor: learners who differ on it differ in outcomes
Related Claims¶
- Stronger cognitive decline is associated with greater likelihood of low health literacy, but only memory decline remains significant after adjusting for educational level — related
- Health literacy measures are strongly correlated with fluid and crystallized cognitive abilities in older adults — related
- Lower health literacy and weaker cognitive abilities are associated with poorer performance on common healthcare tasks — related
- Measures of everyday functioning and independent living correlate with psychometric cognition, with stronger relations for fluid reasoning than for crystallized knowledge — related
- Poorer current cognitive functioning in all domains is associated with low health literacy in older adults — related
- Poorer past cognitive functioning (measured 10 years earlier) is associated with low health literacy in older adults — related
