Question

Quizplus · Accepted Answer

Perceived behavior control refers to an individual's beliefs about their ability to perform the behavior in question, and it is a strong predictor of behavioral intention. If Tom does not believe that he has control over his ability to quit smoking, he may not form a firm intention to do so. While attitudes and subjective norms are also important factors in the theory of planned behavior, perceived behavior control is most likely to interfere with Tom's ability to form a firm intention to quit. Attitude accessibility is not a factor in the theory of planned behavior.
