ABSTRACTThis study examines the influence of individuals' values and lifestyles on the use of information and communication technologies. In particular, an adaptation of the VALS scale to the Spanish case is carried out and the influence of the identified values in the acceptance of information and communication technologies that are in different stages of their life cycle (mobile telephone system, Internet and e-commerce) is examined. The application of the VALS scale to Spain allows six dimensions to be identified: the search for innovation, tendencies, manual skills, intellectualism, conservatism and leadership. The empirical evidence obtained reveals that the search for innovation, interest in tendencies, intellectualism and leadership have a positive influence on the acceptance of the studied innovations. However, conservatism has a negative influence on the use of these technologies.INTRODUCTIONThe current competitive context is characterized by an acceleration of the innovation adoption and diffusion processes that as a result causes a reduction of the life cycle of products (Bayus, 1994; LaBahn, Ali & Krapfel, 1996). Thus, the launch rate of new products grows exponentially, particularly in the field of information and communication technologies, where new technical standards are constantly emerging. This phenomenon is particularly obvious in the sector of communications, which has undergone a continuous revolution over the last ten years with the introduction of Internet and the spread of the mobile phone system. Likewise, the rate of technological development seems to indicate that this process will continue, even more intensively, for the next decades.In this context, very diverse approaches have tried to identify the factors that determine the adoption of new information and communication technologies by final consumers. Regarding this subject, it is worth mentioning the research venue focused on the study of demographic characteristics of the most prone group to use this type of innovations (Korgaonkar & Wolin, 1999; Bhatnagar, Misra & Rao, 2000; Kau, Tang & Ghose, 2003). Likewise, in literature about the adoption of new technologies, the study of the influence of psychographic variables, such as the individuals' personality features (Pratt & Chudoba, 2006; Nov & Ye, 2008) or their attitudes and beliefs with regard to diverse information and communication systems, acquires special relevance (Lee, Kozar & Larsen, 2003; Rodriguez del Bosque & Herrero, 2005). However, there are very few studies inside this research venue that have dealt with the effect of consumers' values and lifestyles in the adoption of information and communication technologies (DuttaBergman, 2002; Chan & Leung, 2005). Therefore, although the influence of values and lifestyles is included in the main models of consumer behavior (Engel, Kollat & Blackwell, 1986; Kotier & Keller, 2006), there is an outstanding lack of empirical evidence with respect to its impact on the acceptance and diffusion of new technologies.On the other hand, research on the psychographic factors that determine the use of new technologies hasn't paid enough attention to the behaviour differences derived from their level of novelty or innovation. However, traditional models of innovation diffusion reveal that an early acceptance of a new product by consumers is determined by these characteristics (Bass, 1969; Rogers, 1983, 1995; Mahajan, Muller & Bass, 1990). So, literature about innovation diffusion has identified diverse psychological variables that determine the acceptance or use of a new product or technology such as personal innovativeness (Gatignon & Robertson, 1985; Goldsmith & Hofacker, 1991) or the search for novelty (Hirschman, 1980). Likewise, the literature about consumer behavior has identified different values and lifestyles that are very similar to these ones (e.g. experimentalism or novelty seeking) and that affect consumers' consumption habits (Steenkamp, Hofstede & Wedel, 1999). …
