To analyze the reliability and validity of a sub-health symptom check scale for college students.
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.
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.
The scale is reliable, effective, and sensitive, and could be applied to evaluate the sub-health status of college students.
分析大学生亚健康症状检查表的信度与效度。
采用多阶段整群抽样法，对长沙市1200名大学生进行亚健康症状检查表测试；共收到1143份有效问卷，用以评估内部一致性信度系数和分半信度系数；111名学生在14天后进行重测以评估量表的信度，112名学生同时接受症状自评量表90（SCL - 90）测试以评估量表的效标关联效度。
问卷的克朗巴哈α系数为0.946，重测相关系数为0.701。以SCL - 90为标准，量表的效标关联效度为0.875。量表得分在性别以及亚健康与健康学生之间存在显著差异。
该量表可靠、有效且敏感，可用于评估大学生的亚健康状态。
