摘　　要：本研究探讨家庭收入与青少年睡眠质量的关系以及歧视知觉、自尊在其中的中介作用。采用家庭收入问卷、歧视知觉问卷、Rosenberg自尊量表(SES)与匹兹堡睡眠质量指数(PSQI)对广东省某地区两所中学1053名青少年进行匿名施测。结果发现:(1)以PSQI得分≥8作为睡眠问题的参考界值,青少年睡眠问题的检出率为15.60%;(2)歧视知觉、自尊在家庭收入与青少年睡眠质量关系中起链式中介作用。因此,家庭收入既直接影响青少年的睡眠质量,又通过歧视知觉、自尊的链式中介作用影响青少年的睡眠质量。With the rapid growth of China＇s economy, the widening income gap and its detrimental effects on adolescents＇ development have receivedsubstantial attention. A large body of research has documented the negative association between low family income and adolescents＇ adjustment.The present study aimed to examine the relationship between low family income and adolescents＇ sleep quality. Sleep is especially importantduring adolescence. There is considerable evidence suggesting that sleep is a powerful predictor of adolescents＇ mental, physical, and psychologicalconsequences.

To our knowledge, most researches have focused on the direct effect of low family income on adolescents＇ sleep quality, however, littleis known about the mediating mechanisms （i.e., how does low family income relate to adolescents＇ sleep？） underlying this relation. Determining theroles of mediators in the relationship between low family income and adolescents＇ sleep would be important to provide guidance for interventions toimprove sleep quality. Thus, the purposes of the present study were to examine the relationship between family income and adolescents＇ sleep qualityas well as the chain mediating effect of perceived discrimination and self-esteem in the relationship between family income and adolescents＇ sleepquality. A number of 1053 adolescents （mean age = 14.95 years, SD = 1.66） in Guangdong Province was recruited to participate in this study. Participantsanonymously completed the questionnaires of family income, perceived discrimination, Self-Esteem Scale （SES）, and Pittsburgh Sleep Quality Index（PSQI）. We first calculated the descriptive statistics for our variables of interest, then processed the bivariate associations among these variables in theSPSS 21.0 software, and finally conducted a follow-up structural equation modeling （SEM） using Mplus 7.0.
