The Health Belief, for example, posits that healthy behaviors are a product of individuals’ health knowledge, the perceived benefits of healthy behavior adoption, and the perceived risks of not taking action.
Although this approach is successful in predicting behaviors
such as exercise and diet in relatively homogenous
samples (see Campbell, Khan, Cone, & Raisch, 2011), it falls
short in that it does not provide a framework for how
healthy behaviors may change over time.
