O efeito enquadramento nas decisões sobre a divulgação de informações pessoais : um estudo experimental no âmbito dos aplicativos móveis

Abstract

This thesis aims to determine the framing effect on users' decisions about disclosure of personal information for use of mobile applications (apps), in relation to their privacy concerns. For this purpose, was verified the relationship between privacy concern and future intention to disclose personal information (future intention); the effect of negative framing of trust belief and positive framing of risk beliefs in future intention; and the moderating effect of framings mentioned on relationship between privacy concern and future intention. To verify these effects, was made an experiment with single-factor independent groups design with use of covariate, with 405 participants. The results indicate that privacy concern is negatively related to the future intention, confirm the effects of framings in future intention, being negative the effect in relation to negative framing of trust belief and positive beliefs in relation to positive framing of risk beliefs, while the moderating effect has not been confirmed. Thus, this thesis contributes to two specific areas: 1) privacy, because confirms the relationship between privacy concern and future intent (new proposed scale); and 2) decision-making, as demonstrated the framing effects of risk beliefs and trust beliefs in the future intention, as far as is known, in a way not performed in any other study.
