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

The current research uses an extended theory of planned behavior (TPB) model to predict Facebook users’ (<italic>N</italic> = 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. [ABSTRACT FROM AUTHOR]
