An Introduction to Abstracts: Types and Linguistic Features
Abstracts are brief summaries of Research Articles (RA) which are placed at the beginning of a page between the cover page and the introduction section. They are intended to substitute the summary that could be usually found at the end of an article. In accordance with Pitkin (1987), abstracts are meant to provide the reader with a sense of direction of the piece of writing, that is, they allow readers to determine to what extent a research article is of their interest. The aim of the present paper is to analyze four different abstracts from the field of medicine articles.
An abstract does not always follow the same pattern in shape since it will depend on its type (APA, 2007), that is to say, “a report of an empirical study should contain a statement of the problem, subjects, method, findings and conclusions” (Pintos & Crimi, 2010) whereas reviews and theoretical articles will require other elements such as “topic, purpose, sources and conclusion” (Ditto.). However, writers tend to pursue standard patterns which include the Introduction – Method – Results – and – Discussions (IMRD) formula moreover types of abstracts may also depend on their internal structure i.e. whether they are informative, indicative, structured or unstructured (Swales & Feak, 1994, as cited in Pintos & Crimi, 2010). The four abstracts analyzed fulfill some of these requirements, for example, Wijeysundera, Beattie, Elliot, Austin, Hux & Laupacis’ (2010) paper seems to be informative because it depicts what researchers did besides it includes large data in the results. Moreover, it can be observed that it is structured in shape since it contains bolded headings which identify the main sections in the research article (Pintos & Crimi, 2010).
Regarding linguistic features in abstracts, Swales and Feak’s (1994) description establishes the use of full sentences and past tenses as expressed in Martinez, Assimes, Mines, Aniello & Suissa’s (2010) article “We used conditional logistic regression (…) compared with current use of fluoxetine, citalopram or dosulepin.”. Although writers have a tendency to avoid using negatives, one of the abstracts analyzed appears to employ negative words which may suggest that the results were not good enough such as “There was a decline of 2% (…) in the same 10 year period.” (Jorgensen, Zahl & Gotzsche, 2010). In accordance with Swales & Feak (1994, cited in Pintos & Crimi, 2010) conclusions tend to be written in present and sentences that describe results tend to show tense variation, thus, Beckett’s et al (2008) paper makes use of those tenets “The results provide evidence (…) is beneficial.”
All in all, the four abstracts follow the requirements established in Swales & Feak (1994) and in the American Psychological Association (APA, 2007) manual, that is, information has been included in abstracts according to their types, thus, that information has not been longer than 200 words. Linguistic features have been used accurately which means that writers made use of full sentences, past and present tenses, and avoided the use of negatives. The only difference found was the organization of text in an article i.e. it displays the text using one column page however, the other articles show the text in a two columns page. Variation in organizing the data may take place because there have been analyzed papers from two different medical journals which may follow other conventions in academic writing.
