摘要
目的构建临床研究考核评估体系并进行实际应用,探讨该指标体系的信度与效度检验及区分度,评价其效果。方法整群随机抽样抽取54个临床科室,以科室为单位,将每个科室的全部个体作为调查对象进行问卷调查与实证分析研究。应用克朗巴哈系数、因子分析验证指标体系的信度和效度,相关系数法进行区分度分析,t检验法计算区分度,采用极端分组法对比高分组与低分组每个指标的差异,验证指标的区分度。结果整套指标的总体α系数为0.840,通过探索性因子分析,提取4个公因子,累积贡献率为56.278%。通过相关系数法与t检验法分析,结果显示:除"结题情况"、"进驻临床研究科学家工作站人次"与"入选人才类临床研究计划人次"外,其余指标的差异均具有统计学意义(P<0.05),区分度指数在0.31~0.64之间。结论该临床研究考核评估体系具有较好的信度与效度,且区分度良好,能够准确的考核评估临床研究情况,对临床效能考核具有借鉴意义。
Objective To construct assessment and evaluation system of clinical research and its application in practice.To explore the reliability,validity and discrimination of this index system,and evaluate its effect.Methods The cluster was randomly sampled from 54 clinical departments.Taking the department as units,all individuals in each department was conducted a questionnaire survey for empirical analysis.Cronbach's coefficient and factor analysis were used to verify the reliability and validity of the index system.The correlation coefficient method was used to analyze the discrimination.The t-test method was used to calculate the discrimination.Extreme grouping method was used to compare the difference between high grouping and low grouping to validate the difference of each index.Results Cronbach′sαof the whole index system is 0.840.Through exploratory factor analysis,four common factors were extracted,and the cumulative contribution rate is 56.278%.Through correlation coefficient method and t-test method,results show that except for the"concluding situation","number of visitors to clinical scientists workstation"and"personnel selected into talent category clinical research program",the differences of other indicators were statistically significant(P<0.05),and the distinguish index was between 0.31 and 0.64.Conclusions The clinical research assessment system has good reliability and validity.And the discrimination is good.The index system can accurately assess the clinical research situation.It can be used for reference in assessment of clinical efficiency.
