The aim of this study was to evaluate the salivary alpha-amylase level under psychological stress and its relationship with rumination and the five personality traits. Materials and methods: In a cross-sectional study, 45 medical students who wanted to take final exams were selected using simple random sampling. NEO Personality Inventory-Short Form and emotional control questionnaire (ECQ) were completed two months before the exam. Saliva samples were taken from the students in non-stressful (control) and stressful conditions. SSA level was measured by photometry and data was analyzed using paired samples t-test, Pearson correlation analysis and stepwise regression. Results: Results: A significant difference was found between the mean of SAA level in the rest and under exam stress. Also, we found a significant correlation between SAA level with neuroticism (P %> http://jmums.mazums.ac.ir/article-1-5826-en.pdf %P 22-33 %& 22 %! %9 Research(Original) %L A-10-4333-68 %+ MSc Student in Clinical Biochemistry, Student Research Committee, School of Medicine, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran %G eng %@ 1735-9260 %[ 2015
