The theory of reasoned action (Ajzen & Fishbein, 1980) and the theory of planned behavior (Ajzen, 1985) are compared in terms of predictive validity and a comparison between behavioral expectation (BE) and behavioral intention (BI) as the immediate antecedent of behavior is offered. In addition, the relationships between attitude‐toward‐the‐act (Aacf), subjective norm (SN), and perceived behavioral control (PBC) as predictors of BE are examined. Results indicate that the theory of planned behavior is a better predictor of intention than the theory of reasoned action and that BI is a stronger predictor of behavior than BE. The results also suggest that Aact, SN, and PBC are better predictors of BI than of BE and that development of a behavioral plan moderates the Aact‐BI‐B relations.
