Objective: To examine associations among college students' worry about COVID-19, use of healthy and unhealthy coping techniques, and sleep-related impairment. Participants: The sample consisted of 366 undergraduate students (M[subscript age] =19.48 ± 1.76 years, 63.4% women; 62.6% college freshman). Methods: University students completed a series of questionnaires. Results: COVID-19 worry significantly predicted greater sleep-related impairment ([beta] = 0.27, t = 5.23, p < 0.001). Students who implemented unhealthy coping strategies experienced more sleep-related impairment ([beta] = 0.24, t = 4.82, p < 0.001), whereas students employing healthy coping strategies reported less sleep-related impairment ([beta] = -0.19, t = -3.88, p < 0.001). Unhealthy coping moderated relations between COVID-19 worry and sleep-related impairment, such that the relationship between COVID-19 worry and sleep-related impairment was stronger among students reporting average (at the mean) to high (+1 SD) unhealthy coping scores. Conclusions: Engaging in unhealthy coping techniques emerged as a significant risk factor for worse sleep among college students.
