Abstract

OBJECTIVES
To compare the quality improvement of the abstracts of original articles, according to the revised manuscript format, of the Korean Journal of Preventive Medicine (Korean J Pre Med) was adopted in 1999. METHODS: A total 63 abstracts for 1997, and 49 for 2001, were selected as the original articles from the Kor J Pre Med. This study was carried out by the separate-sample pretest-posttest design. The quality of the abstracts was measured by a checklist of Narine' evaluation criteria, and the other information related to the articles were also surveyed by e-mail and fax or telephone using a self-made questionnaire. From the response rate, a total of 62 abstracts for 1997 and 49 for 2001 were finally analyzed. RESULTS: The mean number of words in an abstract decreased from 285 in 1997, to 250 by 2001. The mean number of key words per abstract decreased from 3.9 in 1997, to 3.6 by 2001. The mean number of inappropriate usage of key words per abstract, by the MeSH standard, decreased from 1.9 in 1997, to 0.4 by 2001. Also, the overall mean score of abstract quality increased from 0.54 in 1997 to 0.61 by 2001. The range of scores for the abstract quality was better in 2001 (0.40~0.77) than in 1997 (0.20~0.81). From the multiple regression analyses of the 1997 and 2001 databases, the intervention of the manuscript format's revision, and the number of English words to the quality score of the abstract, were the only statistically significant factors. CONCLUSIONS: In conclusion, the quality of abstracts in the Kor J Pre Med has improved since the revised manuscript format was adopted in 1999. The Korean Society for Preventive Medicine will continuously recommend proposals for more informative abstracts in their journal, and will evaluate the abstracts' content with quality criteria. Future studies should address these issues, and compare the quality of abstracts between different international and domestic journals.
