Predicting and understanding behavioral volitions: the interplay between goals and behaviors

In traditional attitude research behavioral volitions have been usually considered in isolation from the broader context that justify their formation. Most behaviors are functional to goal achievement and can be better understood and predicted by considering relevant constructs at the goal level. The interplay between behaviors and goals is the focus of this study. Constructs specified by the Theory of Planned Behavior (TPB) are examined together with constructs proposed by the Model of Goal-directed Behavior (MGB) and two further goal constructs (goal desires and goal perceived feasibility). These theoretical ideas are tested on a sample of 104 students having a goal for body weight regulation or for studying effort. The results indicate that the inclusion of distal goal-related constructs significantly improve the prediction of behavioral volitions, over and above the prediction based on behavior-related constructs. The MGB and an extended model outperform the TPB and show substantial predictive power. The implications of the findings for research on behaviors and goals are discussed.
