A more reasoned approach to improving health literacy embraces the
ecological model when designing interventions and employs theory-based logic
models to facilitate actualization of the comprehensive model. Adopting an
integrated behavioral health theory that operationalizes constructs of perceived
benefits and threats, self-efficacy and social norms, along with broader social
planning theory, could result in a powerful tool to design effective multilevel
interventions to improve health literacy. The currently limited empirical data
on the application of theory-based logic models to health literacy lends urgency
to such a rigorous analysis, especially given the dramatic personal, economic,
and health systems impact of poor health literacy.
