医学生考前焦虑情绪与唾液皮质醇、睡眠质量、心理健康的关系

The Relationship between Anxiety and Salivary Cortisol,Sleep Quality,Mental Health in Medical College Students.

目的探讨医学生在期末考试前焦虑情绪与唾液皮质醇、睡眠质量和心理健康的相关性。方法以状态-特质焦虑问卷(STAI-FormY)、唾液皮质醇、匹兹堡睡眠质量指数(PSQI)、症状自评表(SCL-90)为评价工具。采用方便取样的方法,于期末考前5周和考前3天,共测2次,调查某医学院二年级药学专业43名学生的焦虑状态与相关生理、心理指标及其变化趋势。结果高焦虑组的SCL-90总分、日间功能和主观睡眠质量均高于无焦虑组和轻焦虑组,但组间唾液皮质醇没有差异;4周后,状态焦虑没有显著变化,轻度焦虑组的皮质醇水平有明显的下降趋势;相关分析显示,焦虑与SCL-90总分、睡眠总分有显著正相关关系,而与皮质醇没有显著相关关系。结论自评焦虑与心理健康综合水平、主观睡眠质量有较稳定的相关关系,而与唾液皮质醇的相关关系不明确。
