Strength
At first, the theory of planned behavior can cover people's non-volitional behavior which cannot be explained by the theory of reasoned action.
An individual's behavioral intention cannot be the exclusive determinant of behavior where an individual's control over the behavior is incomplete. By adding "perceived behavioral control," the theory of planned behavior can explain the relationship between behavioral intention and actual behavior.
Several studies found that the TPB would help better predict health-related behavioral intention than the theory of reasoned action (Ajzen, 1988). The TPB has improved the predictability of intention in various health-related fields such as condom use, leisure, exercise, diet, etc.
In addition, the theory of planned behavior as well as the theory of reasoned action can explain the individual's social behavior by considering "social norm" as an important variable.
