The Health Belief Model suggests that people must feel threatened by their current behavioral pattern to succeed in behavioral change.
Step-by-step explanation:
The model that suggests that for behavioral change to succeed, people must feel threatened by their current behavioral pattern, is known as perceived susceptibility and severity. This model is often associated with the Health Belief Model, which is a psychological framework used to understand and promote behavior change in health-related contexts. According to this model, individuals are more likely to change their behavior if they perceive themselves as susceptible to a health threat and believe that the consequences of that threat are severe.
