The current study offers a comprehensive assessment of psychosocial functioning and academic performance in relation to circadian phase preference in a US sample of undergraduate college students (N = 838), aged 17-26 (M = 19.78, SD = 1.89). Women had greater morning preference than men, and seniors had greater morning preference than freshmen. Circadian phase preference, fatigue, perceived stress, depression, anxiety, and substance use were assessed cross-sectionally and grade point average (GPA) was assessed prospectively. Evening phase preference was related to higher levels of fatigue, alcohol and caffeine use, and worse academic performance than morning or intermediate phase preferences.
本研究在美国 17-26 岁（M=19.78，SD=1.89）的大学生样本中，综合评估了与昼夜节律相位偏好相关的心理社会功能和学业表现（N=838）。女性比男性更倾向于早起，高年级学生比新生更倾向于早起。昼夜节律相位偏好、疲劳、感知压力、抑郁、焦虑和物质使用情况进行了横断面评估，而平均绩点（GPA）则进行了前瞻性评估。与早晨或中间阶段偏好相比，傍晚阶段偏好与更高水平的疲劳、酒精和咖啡因使用以及更差的学业成绩有关。
