Precaution Adoption Process Model (PAPM)

I have come across theoretical model known as the Precaution Adoption Process Model (PAPM) with its limited explanations and usage in predicting behaviors. The Precaution Adoption Process Model (PAPM) is a convenient framework for assessing where a person is in the process of deciding to take action on health behavior (Corner & Sparks, 1996).
