__________ of health behavior take(s) a "one size fits all" approach.

A) Stage theories
B) Continuum theories
C) Response efficacy
D) Stages of change

Continuum theories of health behavior are based on the assumption that health behaviors exist along a continuum and that interventions can be designed to target individuals at any point along this continuum. This approach contrasts with stage theories, which propose that individuals move through a series of discrete stages when changing a behavior. Continuum theories do not segment individuals into stages but rather view behavior change as a process that varies in degree across individuals, hence the "one size fits all" approach.
