Objective.本研究的目的是检查意大利和美国青少年自我报告的睡眠质量和睡眠卫生之间的关系，并评估睡眠卫生习惯是否介导文化和睡眠质量之间的关系。从意大利的罗马和密西西比的哈蒂斯堡的公立学校收集了两个非概率样本。学生完成了以下自我报告的措施：青少年睡眠-觉醒量表，青少年睡眠卫生量表，青春期发育量表，早晨/晚上量表。最终样本包括776名意大利和572名美国12至17岁的青少年。意大利青少年的睡眠卫生和睡眠质量都比美国青少年好得多。在这两个样本中，睡眠卫生和睡眠质量之间存在中度到强烈的线性关系。对两种样品进行单独的分层多元回归分析。人口统计学和个人特征解释了睡眠质量的显著差异（意大利人：18%;美国人：25%），睡眠卫生领域的增加解释了睡眠质量的显著差异（意大利人：17%;美国人：16%）。最终的分层多元回归分析显示，在控制了睡眠卫生和所有其他变量后，文化（意大利vs美国）仅能解释0.8%的睡眠质量差异。睡眠质量的跨文化差异在很大程度上是由于睡眠卫生习惯的差异。睡眠卫生是意大利和美国青少年睡眠质量的重要预测因素，因此支持实施和评估良好睡眠卫生习惯的教育计划。
Objective. The purpose of the study was to examine the relationship between self-reported sleep quality and sleep hygiene in Italian and American adolescents and to assess whether sleep-hygiene practices mediate the relationship between culture and sleep quality.Methods. Two nonprobability samples were collected from public schools in Rome, Italy, and Hattiesburg, Mississippi. Students completed the following self-report measures: Adolescent Sleep-Wake Scale, Adolescent Sleep Hygiene Scale, Pubertal Developmental Scale, and Morningness/Eveningness Scale.Results. The final sample included 776 Italian and 572 American adolescents 12 to 17 years old. Italian adolescents reported much better sleep hygiene and substantially better sleep quality than American adolescents. A moderate-to-strong linear relationship was found between sleep hygiene and sleep quality in both samples. Separate hierarchical multiple regression analyses were performed on both samples. Demographic and individual characteristics explained a significant proportion of the variance in sleep quality ( Italians: 18%; Americans: 25%), and the addition of sleep-hygiene domains explained significantly more variance in sleep quality ( Italians: 17%; Americans: 16%). A final hierarchical multiple regression analysis with both samples combined showed that culture ( Italy versus United States) only explained 0.8% of the variance in sleep quality after controlling for sleep hygiene and all other variables.Conclusions. Cross-cultural differences in sleep quality, for the most part, were due to differences in sleep-hygiene practices. Sleep hygiene is an important predictor of sleep quality in Italian and American adolescents, thus supporting the implementation and evaluation of educational programs on good sleep-hygiene practices.
