Relationships among psychological stress, achievement motivation and psychological capital in college students / 中国学校卫生

Objective@#This study explored the relationships among psychological stress, achievement motivation and psychological capital in college students to provide a reference for improving the level of psychological capital in college students.@*Methods@#A multi stage stratified cluster sampling method was used to select 9 940 college students from ten universities in Anhui Province. The achievement motivation scale (AMS), psychological stress scale (SRQ-20) and psychological capital scale (PPQ) were applied. The moderating effect of the questionnaire was analyzed with χ 2 tests, Spearman rank correlation and stratified regression.@*Results@#Statistical differences were found in psychological stress according to major, whether students leader, family economic status and whether students had left behind experience ( χ 2=15.50, 10.25, 28.61, 25.55, P <0.05). The rank correlation results indicated that psychological stress was negatively correlated with the pursuit of success ( r =-0.27) and four dimensions of self efficacy,optimism,hope and resilence in psychological capital ( r =-0.43, -0.41,-0.36,-0.45)( P <0.05), and was positively correlated with the avoidance of failure ( r =0.25, P <0.05). The stratified regression model indicated that psychological stress in the dimensions of college students achievement motivation (pursuit of success: β =0.02, Δ R 2=0.01, P <0.01; failure avoidance: β = 0.03 , Δ R 2=0.01, P <0.01) played a moderating role in the relationship between psychological capital and psychological capital.@*Conclusion@#Being female, senior students, low household economic status, and left behind experience are associated with more psychological stress among college students. Psychological stress is correlated with achievement motivation and psychological capital, and has a moderating effect on the relationship between achievement motivation and psychological capital.

Comparison and evaluation of abnormal result detection methods of platelet / 医疗卫生装备

Objective To compare the clinical values of impedance method,optical method and microscopy when used to detect platelet abnormal results.Methods Platelet re-examinations by optical method and microscopy were carried out in case of low confidence degree in platelet test with impedance method by XE-2100 automatic hematology analyzer,and then the results by the three methods were compared.Results Most of the low-confidence-degree results by impedance method could be corrected by re-examination by optical method,and the remained had to turn to microscopy due to unsatisfied requirements of the instrument.Conclusion Optical method has to be involved to correct the platelet abnormal results by XE2100 automatic hematology analyzer,and microscopy should be applied in case optical method doesn't work.The three methods gains advantages and disadvantages of themselves,and can be supplementaries for one another.
