Smartphone ownership and engagement are at an all-time high. Excessive smartphone use may impart smartphone-specific anxiety; specifically, the fear of being unable to access or use one's smartphone, or nomophobia. Young adults, in particular, are at higher risk for nomophobia, given higher ownership of and engagement with smartphones. Notably, little research has been done in a Canadian context. Objective: To conduct an environmental scan of nomophobia prevalence in a Canadian university. Participants: Full-time and part-time university students. Methods: The Nomophobia Questionnaire and demographics were collected via mass emailer of all students at the host institution (n = 1,002). Results: Findings indicate moderate-to-high levels of nomophobia among respondents, with nearly a quarter of respondents reporting severe nomophobia. Respondents who identified as women were an undergraduate, and/or owned an Apple device reported significantly higher nomophobia. Conclusions: This study provides evidence for comparable levels of nomophobia between Canadian post-secondary students and recent global research. Future research should explore nomophobia within a more nationally representative sample.
