title: Multilevel analysis exploring the links between stress, depression, and sleep problems among two-year college students.
abstract: OBJECTIVE
  This study explored the association of stress and depression with a multidimensional sleep problems construct in a sample of 2-year college students.
  
  
  METHODS
  The sample consisted of 440 students enrolled in 2-year study from Fall 2011 to Fall 2013.
  
  
  METHODS
  Participants in an obesity prevention study completed surveys assessing sleep, stress, and depression at baseline, 4, 12, and 24 months. Multilevel models predicting sleep problems were conducted to distinguish episodic from chronic reports of stress and depression.
  
  
  RESULTS
  Participants were primarily women (68%), white (73%), young adults (M age = 22.8), with an average of 8.4 hours of sleep per night. Neither stress nor depression was predictive of sleep quantity; however, they were predictive of sleep quality.
  
  
  CONCLUSIONS
  Results show that sleep quality rather than sleep quantity may be the greater health concern for young adults, suggesting that intervention programs targeting depression, stress management, and healthy sleep patterns are warranted.
