Within the short timeframe of the COVID-19 pandemic, there has been increasing interest in its potential impact on psychological stress and sleep. Using standardized self-report measures, we examined differences in stress and sleep by comparing responses from three independent samples of undergraduates in the United States. Samples were obtained prior to COVID-19 (Spring 2019) and at two periods during the pandemic (Spring 2020 and Summer 2020) which corresponded to an increasing impact of COVID-19 at the local level. Within the combined sample of 1222 students, 94% identified as Hispanic. Contrary to our hypotheses, stress, sleep quality and insomnia were not significantly higher in the samples collected during the COVID-19 pandemic. However, in support of our hypotheses, bedtime and waketime were significantly later during the pandemic, and sleep duration was significantly longer. Although scores on the global measure of sleep quality did not differ across semesters, supplemental exploratory analyses demonstrated a more complex picture of differences in sleep variables. Among the findings, there was evidence of greater sleep latency, greater sleep medication use and poorer sleep efficiency during the pandemic. Our results suggest that, within the US college student population, COVID-19's impact on stress and sleep may not be entirely negative.

COVID-19 大流行之前和期间大学生的压力和睡眠

在 COVID-19 大流行的短时间内，人们对其对心理压力和睡眠的潜在影响越来越感兴趣。使用标准化的自我报告措施，我们通过比较来自美国本科生的三个独立样本的反应来检查压力和睡眠的差异。样本是在 COVID-19 之前（2019 年春季）和大流行期间（2020 年春季和 2020 年夏季）获得的，这与 COVID-19 在当地的影响越来越大相对应。在 1222 名学生的合并样本中，94% 被认定为西班牙裔。与我们的假设相反，在 COVID-19 大流行期间收集的样本中，压力、睡眠质量和失眠并没有显着升高。然而，为了支持我们的假设，大流行期间就寝时间和起床时间明显推迟，并且睡眠时间明显更长。尽管各学期睡眠质量的全球测量得分没有差异，但补充探索性分析显示了睡眠变量差异的更复杂图景。在调查结果中，有证据表明大流行期间睡眠潜伏期更长、睡眠药物使用量更大、睡眠效率更低。我们的结果表明，在美国大学生群体中，COVID-19 对压力和睡眠的影响可能并不完全是负面的。大流行期间更多的睡眠药物使用和更差的睡眠效率。我们的结果表明，在美国大学生群体中，COVID-19 对压力和睡眠的影响可能并不完全是负面的。大流行期间更多的睡眠药物使用和更差的睡眠效率。我们的结果表明，在美国大学生群体中，COVID-19 对压力和睡眠的影响可能并不完全是负面的。
