Abstract

OBJECTIVES
The purpose of this study was to evaluate the quality of abstracts of original articles.
METHODS
This subjects selected total 63 abstracts of the original articles of the Korean Journal of Preventive Medicine in 1997. The quality of abstracts was measured against a checklist of evaluation criteria, which were divided into eight categories and the numbers of inappropriate words (including grammar) according to criterion-based survey. A score for each abstract was obtained by dividing the number of criteria presented by the number applicable. The overall mean score was also determined.
RESULTS
The overall mean score of abstract quality was 0.55 out of 1. Of the abstracts subject selection 83% didn't include specific technical descriptors. Of those that gave conclusions 92% didn't address study limitations and 78% made no recommendations for future study. The overall mean number of inappropriate usage of words (including grammar) per abstract was 14.1. The overall mean number of English words was 283. In the multiple regression analyses, the research career of the first author and the number of English words to the number of inappropriate usage of words were statistically significant. Also, in the secondary regression model, the number of English words to the quality score of abstract was only statistically significant.
CONCLUSIONS
Most of the abstracts provided some information pertaining to each evaluation criterion. However, they did not provide sufficient details to enhance the reader's understanding of the article. On the basis of the study the abstracts need improvement in its description of the reported subject selection, statements of limitations and recommendations, etc. The Korean Society for Preventive Medicine will recommend a proposal for more informative abstracts in Korean J Prev Med and will take into consideration the introduction of foreign review of abstracts. Future studies should address these issues and compare the quality of abstracts between different journals and their time of publication.
