title: [Reliability and validity of a sub-health symptom check scale for college students].
abstract: OBJECTIVE
  To analyze the reliability and validity of a sub-health symptom check scale for college students.
  
  
  METHODS
  Using a multi-phase cluster sampling method, a total of 1200 college students from Changsha city were tested with a sub-health symptom check scale; 1143 valid questionnaires were received to assess the internal consistency reliability coefficient and split-half reliability coefficient; 111 students were retested 14 days later to assess the reliability of the scale, 112 students were also tested with the Symptom Checklist 90 (SCL-90) to evaluate the criterion-related validity of the scale.
  
  
  RESULTS
  The Cronbach's alpha coefficient of the questionnaire was 0.946 and the test-retest correlation coefficient was 0.701. Taking SCL-90 as a criterion, the criterion-related validity of the scale was 0.875. The scores of the scale were significantly different in gender and between sub-healthy and healthy students.
  
  
  CONCLUSIONS
  The scale is reliable, effective, and sensitive, and could be applied to evaluate the sub-health status of college students.
