Expanding the Affective and Normative Components of theTheory of Planned Behavior: A Meta-Analysis ofAnticipated Affect and Moral Norms

摘要

Meta-analysis was used to determine the predictive validity of anticipated affect andmoral norms in the theory of planned behavior (TPB; Ajzen, 1991). Medium-to-large sample-weighted average correlations were obtained. Anticipated affect andmoral norms increased the variance explained in intentions by 5% and 3%, respec-tively, controlling for TPB variables. Intention mediated the influence of both vari-ables on behavior. Moderator analyses showed that younger samples and behaviorswith a moral dimension were associated with stronger moral-norm/intention rela-tions, and anticipated regret was associated with a stronger anticipated-affect/intention relation. The implications of the findings for the TPB are discussed.
