title: Effects of exercise dependence on psychological health of Chinese college students.
abstract: BACKGROUND
  The aim of this study was to investigate the effects of exercise dependence on the psychological health of Chinese college students.
  
  
  METHODS
  A total of 1601 college students from three universities in Hunan, China, were selected as research subjects. Several measurement scales, including the Exercise Addiction Inventory, the State-Trait Anxiety Inventory, the Center for Epidemiologic Studies Depression Scale, and the Subjective Well-being Scale, were used to survey the psychological health problem of these students and to analyze the effects of exercise dependence on their psychological health.
  
  
  RESULTS
  Exercise dependence, based on the structural equation model analysis, can positively influence state anxiety (P<0.05), depression (P<0.05), and subjective well-being (P<0.05) of Chinese students. By contrast, exercise dependence negatively influences students' self-satisfaction (P<0.05), social behavior (P<0.05), and vigor (P<0.05).
  
  
  CONCLUSIONS
  Exercise dependence adversely affects the psychological health of college students. Further research using multi-dimensional exercise addiction scales should be conducted to identify all the negative effects of exercise addiction factors on psychological health.
