助产士规范化培训实践技能考试的测量学评价

摘要

目的:评价2016年助产士规范化培训考核实践技能考试的效果.方法:根据经典测验理论重点分析考试难度、区分度、信度、效度及考站内容相关性.结果:本次考核实践技能考试平均成绩为(72.48±8.72)分;考核总体难度为0.691,区分度为0.291,信度为0.582,均在测量学可接受的范围.考核内容效度指标(CVR)为0.90,结构效度的因素分析结果为3个维度,符合考试理论构想.各考站中第1站与第6站、第2站与第5站间存在中等程度相关,其余各考站成绩无明显相关性,说明考站内容互相独立,与考试设计符合.结论:本次考核难度适中,区分度较好,具有良好的信度和效度,能够准确地评价助产士规范化培训考核的效果,对临床实践和教学具有促进作用.%Objective:To evaluate the outcome of practical skills test of midwives standardized training in 2016.Methods:We analyzed the level of difficulty,discrimination,reliability,validityand the correlation between each test station.Results:The average test score was 72.48±8.72.The overall difficulty level of all stations was 0.691.The discrimination was 0.291 and the reliability was 0.582.Each index was within the acceptable range.The content validity index was 0.90.Factor analysis of construct validity yielded three dimensions,which was accorded with the test theory conception.Moderate correlation was shown between the first station and the sixth station,as well as the second station and the fifth station,but no significant correlation between other stations were seen.This indicated that the content of each test station was independent of each other,which was in accordance with the test design.Conclusion:The test shown a moderate difficulty level,proper discrimination,satisfying reliability and validity,which can accurately evaluate the outcome of practical skills test of midwives standardized training assessment and promote clinical nursing as well as teaching work of nursing.
