The Effects of Communication Interface Proximity on User Anxiety for Crime Alerts Received on Desktop, Laptop, and Hand-Held Devices

This experiment investigates effects of communication interface proximity, which was conceptualized as three different media platforms (desktop, laptop, and hand-held device), on college students’ anxiety when receiving emergency alerts about on-campus crimes via emails and text messages. It proposes a new dimension of proximity, interface proximity, and suggests a shift in the emphasis of proximity from audience to event to user to interface. Ninety seven students received alerts on one of the three devices for 2 days. User anxiety increased for news-like information such as crime alerts and varied according to the proximity of the media platform. A three-level model of anxiety, including trait anxiety, media exposure to negative compelling news, and a trigger event, all contributed to participants’ anxiety.
