ABSTRACT
Objective To evaluate the comprehensive influence of preventive medicine journals and provide ideas for the internationalization of "Chinese Journal of Endemiology".Methods The periodicals of impact factor ＞ 1.0 were selected as the research objects in the 2016 edition of "China Science and Technology Journals Citation Report (Core Edition)" in category of preventive medicine and public health comprehensive and epidemiological,and environmental medicine journals.Measurement indicators of 2011-2015 were collected from "China Science and Technology Journals Citation Report (Core Edition)" (2011-2016) of research objects (including total cited frequency,influencing factor,immediacy index,his cited rate,the source of hterature,ratio of international papers,and ratio of fund papers).Academic impact assessment score (I),relative academic impact assessment score (It) and 5-year growth rate of each journal were calculated;the comprehensive influence of journals was compared and analyzed through the dynamic assessment model of academic influence of sci-tech periodicals.Results A total of 8 kinds of Journals were selected as research objects,namely "Public Health and Preventive Medicine","Disease Surveillance","China Public Health","Chinese Journal of Schistosomiasis Prevention and Treatment","Chinese Journal of Endemiology","Chinese Journal of Disease Control","Chinese Journal of Epidemiology",and "Chinese Journal of Preventive Medicine".The average annual citation frequency of the 8 kinds of journals in 5 years were 958.8,1 609.0,5 041.0,1 557.4,1 494.8,1 796.6,4 906.8,and 2 219.0,"Chinese Journal of Endemiology" ranked the 7th.The five-year average impact factors of the 8 kinds of journals were 0.583 2,0.911 2,0.802 4,1.297 0,1.111 0,0.999 6,1.306 2,and 1.186 0,"Chinese Joumal of Endemiology" ranked the 4th.The Ir values of 2011-2015 were 0.12,0.24,3.27,0.48,0.35,0.66,2.59 and 1.06,respectively,"Chinese Journal of Endemiology" ranked the 6th.The five-year growth rate were 1.81％,0.53％,-0.06％,-0.39％,0.57％,0.71％,0.19％,and 0.57％,respectively,"Chinese Journal of Endemiology" ranked the 3rd.Conclusions The overall academic quality of preventive medicine journals is high,but the growth rate is not balanced.In the future,we should focus on increasing the frequency of citation,influencing factors and his citation rate of "Chinese Journal of Endemiology".
ABSTRACT
Objective To evaluate the academic status and influence of "Chinese Journal of Endemiology" in the preventive medicinal core periodicals to provide a scientific basis for further improving the quality of the journal. Methods Journal evaluation data of "Chinese Science and Technology Journal Citation Reports" (2005 -2009 periodicals) as a statistical source, twenty-eight core journals of preventive medicine as an evaluation object, a single evaluation index (such as impact factor, total cites and he cited rate) as a reference, integrated 15 journal evaluation indicators of 28 kinds of preventive medicinial core periodicals into 4 comprehensive evaluation indexes.Calculate the composite indicator score through principal component analysis method if the index's relevant eigenvalue was greater than 1 and their cumulative contribution rate was more than 80%. Then calculated the composite indicator scores of the 4 kinds of indexes, which were weighted into linear combination of the composition with its corresponding contribution. Assess the overall level and the academic quality of "Chinese Journal of Endemiology" among core journals of preventive medicine on the basis of the 4 composite score. Results Impact factors of Chinese Journal of Endemiology were 0.909, 1.237, 0.899, 0.832, 1.019 between 2005 and 2009, ranked number 4, 1, 4, 6 and 3 among the 28 core journals. Its total cited frequency respectively were 933, 1172,1101, 1267 and 1491, among the 28 kinds of core journals and ranked number 4, 4, 6, 5 and 6. Comprehensive score of "Chinese Journal of Endemiology" were 0.269, 0.371, 0.282, 0.247 and 0.602, and its rank were 7th, 5th,7th,5th and 4th in the 28 core journals. Conclusions The impact factor and citation frequency of "Chinese Journal of Endemiology" are ranked at the forefront of preventive medicinal core periodicals. More attention should be paid to academic exchanges of related areas, and to enhance the academic quality of the journal.
