The next article in a series of health education model critiques is the Health Belief Model. This model attempts to explain what beliefs and perceptions will prompt someone to promote or not perform a health behavior. The model was developed in the 1950’s by Godfrey Hochbaum, Irwin Rosenstock, Stephen Kegeles, and Howard Leventhal (Janz & Becker, 1984). Understanding the perceptions of the health behavior is key to understanding why someone will or will not do it.
