This study examines the role of satisfaction strength on the correspondence between reported satisfaction and intention to purchase a new product. The market testing underlying this study analyzes the market opportunities for a novel prototype. The research was conducted at a central location with 239 randomly selected consumers. Results indicate that (un)certainty, ambivalence, and importance cognitions and feelings significantly moderate the relationship between reported satisfaction and individuals' intention to purchase. For example, the association between consumers' reported satisfaction level and purchasing intention of the new product is weaker as uncertainty increases. Significant moderated-mediation and mediated-moderation effects were also found with Structural Equation Modelling. Judgments of ambivalence moderate the satisfaction–purchasing intention relationship through the mediating effect of importance. (Un)certainty fully mediates the moderating effect of importance on the satisfaction–purchasing intention link. The research validates the usefulness of assessing the satisfaction strength concept and illustrates its potential as a better predictor of intentions than satisfaction level alone. The study argues on the nomological validity of the satisfaction construct and reveals that assessment of satisfaction strength should support the management goal of identifying truly satisfied customers.
