Data-driven practices, such as personalized communication, computational advertising, and algorithmic decision making, are now commonplace.

In line with the predictions, the scale was negatively related to personalization attitudes. The Perceived Surveillance Scale can assess differences in perceptions of or responses to data-driven communication in different communication domains.
