Informational Bases of Behavioral Intentions and Behavioral Expectations or Self-Predictions

Ninety subjects were randomly assigned to respond to a list of intention or expectation (self-prediction) questions regarding the performance of social, academic, and health-related behaviors. After responding to these questions, subjects were asked to describe the information they drew on when responding to the questionnaire items. A content analysis conducted on these responses revealed that subjects who completed the intention questionnaire relied more heavily on information regarding behavioral beliefs, and that subjects who completed the expectation (self-prediction) questionnaire focused more on their past behavior and circumstance information. The manner in which the results of the content analysis data support Fishbein and Ajzen's (1975) theory of reasoned action and the way in which these findings are related to the enhanced predictive validity obtained in previous research that employed an expectation question (self-prediction) format are discussed.
