The purpose of this study is to investigate the differences among different age groups (18-25, 26-50, and 50+) and between genders regarding information privacy concerns and their relationships with computer self-efficacy. Computer self-efficacy has been shown to be an effective predictor of behavioral intention (Ball, 2008) and a critical predictor of an individual’s attitude about information technology and usage behaviors (Marakas, Yi, & Johnson, 1998). Consumers’ privacy concerns are complex and practitioners and researchers need to understand antecedents to consumers’ concerns regarding information privacy (Stewart & Segars, 2002). Several studies (Malhotra, Kim, & Agarwal, 2004; Metzger, 2004; Phelps, Nowak, & Ferrel, 2000; Anton, Earp, He, Stufflebam, Bolchini, & Jensen, 2004) have shown that if consumers’ privacy concerns are not understood and mitigated, they can have negative consequences on e-commerce growth and Internet purchases. White et al. (2008) studied the relationship between computer self-efficacy and information privacy concerns. Their study focused on computer self-efficacy and its relationship with four information privacy components (collection of data, errors (data integrity), unauthorized secondary use, and improper access to data) as defined by Smith, Milberg, and Burke (1996). They did not study the differences of relationships between information privacy concerns and computer self-efficacy among different age groups and genders. White et al. (2008) stressed the need to extend their work by examining the differences of the relationships among different age groups and between genders. The goal of this study is to extend their work by investigating differences among different age groups and between genders regarding information privacy concerns and their relationships with computer self-efficacy.
