Clinical evaluation is one of the main pillars of medical education. The Objective Structured Clinical Examination is one of the commonly adopted practical tools to evaluate clinical and practical skills of medical students. The purpose of the study is to determine validity and reliability of Objective Structured Clinical Examination for evaluation of clinical skills of midwifery undergraduate students. Seven clinical skills were evaluated in this descriptive correlative study using a performance checklist. Census method was used for sampling. Thirty-two midwifery students performed the skills at seven stations each monitored by an observer using an evaluation checklist. Criterion validity was obtained through determining the correlation between the clinical and theoretical courses point and the Objective Structured Clinical Evaluation score. The collected data was analyzed in SPSS (v.20) and logistic regression test. The correlation score of Objective Structured Clinical Examination was significantly related to the mean score of clinical course “Normal and Abnormal delivery I” (0.399, p = 0.024) and the mean score of clinical course “gynaecology “(0.419, p = 0.017). There was no significant correlation between OSCE scores and the mean score of theoretical courses (0.23, p = 0. 200). The correlation between the total score and mean score of students at the stations showed that out of the seven stations, the correlations of the stations three (communication and collecting medical history) and four (childbirth) were not significant. Although, it appeared that Objective Structured Clinical Examination was one of the effective and efficient ways to evaluate clinical competencies and practical skills of students, the tool could not evaluate all the aspects.

检验助产本科生临床技能客观结构化临床考试的有效性和可靠性：一项描述性研究

临床评价是医学教育的主要支柱之一。客观结构化临床考试是评价医学生临床和实践技能的常用实用工具之一。本研究的目的是确定客观结构化临床考试用于评估助产本科生临床技能的有效性和可靠性。在这项描述性相关研究中，使用绩效检查表评估了七项临床技能。采用普查法进行抽样。三十二名助产专业学生在七个站点执行了这些技能，每个站点都由一名观察员使用评估清单进行监控。通过确定临床和理论课程分数与客观结构化临床评估分数之间的相关性来获得标准有效性。收集的数据在 SPSS (v.20) 和逻辑回归测试中进行分析。客观结构化临床检查的相关性得分与临床课程“正常和异常分娩I”的平均得分（0.399，p = 0.024）和临床课程“妇科”的平均得分（0.419，p = 0.017）显着相关。OSCE 分数与理论课程平均分数之间不存在显着相关性 (0.23, p = 0. 200)。各站学生总分与平均分的相关性显示，7个站中，站3（交流和收集病史）和站4（生育）相关性不显着。尽管客观结构化临床考试似乎是评估学生临床能力和实践技能的有效且高效的方法之一，但该工具无法评估所有方面。
