A good public health intervention is not only defined by the results they create, but also the number of levels it hits on the socioecological model[6] (individual, interpersonal, community and/or environment).

Tobacco use, alcoholism, multiple sex partners, substance use, reckless driving, obesity, or unprotected sexual intercourse are some examples.
