and individuals may not be aware of their significance in prompting them to engage in a health-related behavior. Interpersonal influences are also particularly difficult to measure as cues. Another reason why research does not always support the HBM is that factors other than health beliefs also heavily influence health behavior practices. These factors may include: special influences, cultural factors, socioeconomic status, and previous experiences. Scholars extend the HBM by adding four more variables (self-identity, perceived importance, consideration of future consequences and concern for appearance) as possible determinants of healthy behavior. They prove that consideration of future consequences, self-identity, concern for appearance, perceived importance, self-efficacy, perceived susceptibility are significant determinants of healthy eating behavior that can be manipulated by healthy eating intervention design.
