The document summarizes the Theory of Planned Behavior developed by Icek Ajzen. The theory proposes that behavioral intentions are influenced by attitude toward the behavior, subjective norms, and perceived behavioral control. It was developed from Ajzen's prior Theory of Reasoned Action which looked at attitude and subjective norms as predictors of intentional behaviors. The Theory of Planned Behavior adds perceived behavioral control to account for behaviors that are not entirely voluntary. It has been used to study health behaviors like safe sex practices, obesity, alcohol and cigarette use. While useful, some critics argue it does not consider all influential factors.
