Abstract:
[Purposes] This study aims to analyze the difference in the effectiveness of journal evaluation between CiteScore in Scopus database and impact factor in JCR.[Methods] Taking the American ophthalmology journals indexed in both SCI and Scopus databases in 2016 as examples, we compared the similarities and differences between the CiteScore and the impact factors (IF2) on the effectiveness of the journal evaluation using the questionnaire score. At the same time, the impact factor in 3-year citation time window (IF3) and the 3-year citation window impact factor obtained from the CiteScore formula (IF3T) were calculated and compared.[Findings] Wilcoxon test results show that CiteScore is smaller than IF2 and IF3, but larger than IF3T, the differences are statistically significant. CiteScore is closer to the normal distribution than IF2, IF3 and IF3T , and the degree of dispersion is smaller. Pearson correlation analysis shows that there exist significant positive correlations between CiteScore, IF2, IF3, IF3T and questionnaire scores. The correlation coefficients of each index and questionnaire scores from big to small are CiteScore (0.727), IF2(0.700), IF3(0.700), IF3T (0.565), respectively.[Conclusions] For the American ophthalmic journals, the effectiveness of CiteScore is similar to IF2 and IF3.

摘要:
目的 分析Scopus数据库新推出的期刊评价指标CiteScore与JCR经典指标影响因子对期刊评价效力的差异。方法 以2016年同时被SCI和Scopus数据库收录的美国眼科学期刊为研究对象,以问卷调查评分结果为标准,对比分析CiteScore与影响因子(IF2)对期刊评价效力的异同。同时计算各期刊3年引证时间窗口影响因子(IF3),及按照CiteScore计算公式获得的3年引证时间窗口影响因子(IF3T),并对上述评价指标进行对比分析。结果 Wilcoxon检验结果显示,CiteScore较IF2、IF3小,但较IF3T大,差异均有统计学意义。CiteScore较IF2、IF3、IF3T更接近于正态分布,离散度更小。Pearson相关性分析结果表明,CiteScore、IF2、IF3、IF3T与问卷调查得分之间均呈显著正相关; 各指标与问卷调查得分的相关系数由大到小分别为CiteScore(0.727)、IF2(0.700)、IF3(0.700)、IF3T(0.565)。结论 CiteScore对美国眼科学期刊的评价效力与IF2、IF3类似。
