Predicting online privacy protection for Facebook users with an extended theory of planned behavior

This is the final version. Available on open access from Routledge via the DOI in this record. Data availability statement: The research was pre-registered prior to data collection and the data and materials are available at https://doi.org/10.17605/OSF.IO/QAZVUThe current research uses an extended theory of planned behavior (TPB) model to predict Facebook users’ (N = 376) intentions to protect their privacy online. It aims to replicate and extend Saeri et al. (2014) who found partial support for an extended TPB model that included descriptive norms, perceived risk, and trust. Facebook users completed an online questionnaire assessing attitudes, norms (subjective and group), perceived behavioral control (PBC), perceived risk, trust, privacy concerns, and intentions to protect their privacy online. Results revealed that attitudes, subjective norms, and PBC (i.e. the TPB) predicted online privacy intentions, as well as descriptive group norms and privacy concerns. However, perceived risk, trust, and injunctive group norms were not significant unique predictors of online privacy intentions. The implications for understanding influences on individuals’ willingness to protect their privacy online are discussed

Understanding adolescents' unfriending on Facebook by applying an extended theory of planned behaviour

© 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group. Becoming friends on Facebook does not always guarantee long-term friendships as users have the possibility to unfriend people. This unfriending behaviour is frequently occurring and might have negative consequences for both parties. To gain insight into the factors influencing adolescents’ unfriending, the current study made use of an extended version of the theory of planned behaviour. To enrich the theoretical framework, we included antecedents related to adolescents’ friendship management on Facebook, namely their number of friends, their friendship acceptance threshold, and their degree of public communication. A cross-sectional survey was conducted among 1.117 adolescents. SEM analyses indicated that both subjective norm and attitude were related to behavioural intention, which in turn was related to adolescents’ unfriending behaviour. Perceived behavioural control was only associated with adolescents’ unfriending behaviour. Regarding the additional factors, the size of adolescents’ friend network was positively related to their confidence in the ability to unfriend people. Adolescents’ friendship acceptance threshold was negatively related to their attitude, whereas adolescents’ degree of public communication was positively associated with their perceived behavioural control and the experienced social pressure to unfriend.status: publishe
