how we do itHealth Behavior Theories


The Health Belief Model (HBM) is a psychological model that attempts to explain and predict health behaviors by focusing on the attitudes and beliefs of individuals.

The key variables of the HBM are as follows:
  • Perceived Threat: Consists of two parts: perceived susceptibility and perceived severity of a health condition.
  • Perceived Susceptibility: One's subjective perception of the risk of contracting a health condition,
    • Perceived Severity: Feelings concerning the seriousness of contracting an illness or of leaving it untreated (including evaluations of both medical and clinical consequences and possible social consequences).
    • Perceived Benefits: The believed effectiveness of strategies designed to reduce the threat of illness.
    • Perceived Barriers: The potential negative consequences that may result from taking particular health actions, including physical, psychological, and financial demands.
    • Cues to Action: Events, either bodily (e.g., physical symptoms of a health condition) or environmental (e.g., media publicity) that motivate people to take action. Cues to actions is an aspect of the HBM that has not been systematically studied.
    • Other Variables: Diverse demographic, sociopsychological, and structural variables that affect an individual's perceptions and thus indirectly influence health-related behavior.
    • Self-Efficacy: The belief in being able to successfully execute the behavior required to produce the desired outcomes.
