Abstract


Understanding how individuals utilize risk messages is important for protecting lives and gaining compliance toward safe behaviors. Recent advances in technology afford users with timeliness when needing to acquire information, and research investigating imperative and declarative message styles suggests utilizing both strategies is most effective. Similarly, the element of time can play a role when an individual engages in certain behaviors. This study employed an experimental design to better understand how imperative and declarative tweets, and time can contribute to risk perceptions and behavioral intentions. Results indicate the most negative affect is experienced after receiving an imperative-only tweet in a short-lead time condition, whereas a tweet utilizing both message styles in a long-lead time condition induces the most fear. Future research should investigate stylistic message elements on new media platforms to better understand how messages can be effectively sent and received by the intended audience within character-limited platforms.
