Store choice has been studied extensively in the literature, but store format choice has had limited research attention. The store format choice for bulk grocery purchase being a rational context is well conceptualized in the Theory of Planned Behavior (TPB) framework. Attitude behaviour linkages are well explored but there is rare consensus on the components of attitude, their interrelationship and resultant impact on conation. The Theory of Reasoned Action has evolved over time to incorporate perceived behavioral control and past behavior to improve its explanatory capability as TPB; however, it has maintained its unidimensionalist approach and has not tested affect and cognition independently for its impact on behavior. This paper explores a Converging framework of the Affect and Cognition components of attitude and tests their independent impact on store format choice behaviour.
