Age differences in adaption of persuasion strategies in advertising

This investigation has three aims: (1) to adapt and modify the STPS questionnaire - developed by Kaptein, Markopoulos, Ruyter and Aarts, (2009) as a basic instrument for measuring achieved social influence; (2) to establish susceptibility to Cialdini's persuasion strategies among different age groups; and (3) to determine the advertising effectiveness achieved through advertising messages- based on persuasion principles. The paper used the adapted and modified STPS questionnaire, measured respondents' individual susceptibility to persuasion strategies relative to their age. The results of the univariate analyses of variance show achieved social influence among different age groups in terms of the principles. For respondents aged 46-55, the principle of social proof and commitment and consistency, are relevant; scarcity is significant for 36-45-years old, while authority is dominant for the 56-65 age groups. Positive correlations were found between the persuasion strategies present in advertising: the presence of the reciprocity principle enhanced the influence of the liking and consistency principles to the greatest extent, while the presence of the scarcity principle enhanced the influence of the authority and reciprocity principles. The consumers’ susceptibility to advertising is greatest when consumers’ willingness to purchase is measured against the principle of reciprocity, authority and social proof. On the other hand, offering a stimulus in advertising is most successful when the principles of scarcity, authority, and commitment /consistency are present, and least successful when the principle of liking is present. In older age groups, different consumer sensitivity to persuasion in advertising can be achieved with different combinations of persuasion strategies. These research findings are useful for organizations that offer products and services through advertising.
