4.3 Behavioral Interventions

When patients develop diseases with strong

behavioral components, such as cardiovascular

disease, behavioral interventions are often

recommended in addition to medical

treatments. In chronic diseases strongly

affected by behavior, changing behavior can

help control the disease. Behavioral and social

science research has provided many new

nondrug interventions for managing chronic

diseases, thus preventing the development

of new diseases and promoting healthy

behaviors.22
