ABSTRACT
Objective To evaluate the quality of the examination paper of the theory of Clinical Diagnostics,to explore and reflect on the teaching methods,so as to improve the quality of teaching.Methods Finals results of Clinical Diagnostics including 40 clinical undergraduates of Capital Medical University were analyzed.SPSS 20.0 was used to make analysis of the frequency,means statistics and normality of the examination paper.Kuder Richardson/Cmnbacha formula,percentage unification methods and so on were used to calculate confidence,validity,difficulty and degrees of distinction.Acquisition of relevant knowledge was assessed according to score distribution,while test paper quality was evaluated based on indicators including confidence,validity,difficulty and degrees of distinction.Results Test scores of 40 students were between 61 to 96 (83.64 ± 8.07).The degree of confidence (γ) for choice questions and subjective questions was 0.65 and 0.59 respectively;The validity (V) was 0.27;The overall difficulty (P) of the examination was 0.84;The degrees of distinction (D) were between 0.16 to 0.30.And the total points losing rate was 16.36％.Conclusion The examination is of medium difficulty and good degree of distinction,but the teaching strategies still need further adjustment in order to improve the students' ability of flexible application of the basic knowledge.
ABSTRACT
BACKGROUND:Many researchers appealed that coronary atherosclerotic heart disease patients were medical treated while special psychological intervention should be integrated into the rehabilitation plans (biology-psychology-social treatment) for coronary atherosclerotic heart disease patients.Pertinence psychological intervention would be processed after finding out mental health state of coronary atherosclerotic heart disease patients.OBJECTIVE:To make principal component analysis for mental health state of coronary atherosclerotic heart disease patients with relapsing pain in chest after percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) by questionnaire investigation,and to find out the primary factors.METHODS:A total of 40 coronary atherosclerotic heart disease patients with relapsing pain in chest after PCI and CABG were selected,(25 males and 15 females),mean age of (60±10) years old.It was used that the mental health section of the integrative system for diagnosing and assessing health state in Chinese population,including body symptoms,positive emotion,negative emotion,cognitive ability,behavior trouble,self-evaluation and social adapting problem.RESULTS AND CONCLUSION:Totally 4 principle component factors which the accumulative contribution rate reached to 83.89% were extracted.The first principle component factors which the contribution rate reached to 40% mainly demonstrated behavior trouble and social adapting problem.The second one mainly demonstrated positive emotion and negative emotion,the third for cognitive ability and self-evaluation,and the fourth for body symptoms.The behavior trouble and social adapting problem of coronary atheroscleroticheart disease patients with relapsing pain in chest after PCI and CABG must be paid great attention,and positive emotion would be leaded,negative emotion would be lowered.
