Abstract:
A scientometric analysis of research articles published in the Ceylon Medical Journal was carried
out with the objectives of 1) mapping the year-wise distributions of papers, 2) examining the
authorship patterns and 3) determining the degree of collaboration between the authors. Ten
volumes of the said journal containing 40 issues from 2009 -2018 were considered for the present
study. Only the research articles (230) published in these 40 issues were considered and others
were excluded from the study. Findings revealed that the highest number of research articles (33)
were published in 2017 with a gradual increase, except in 2018 where a marginal decrease is
found. Out of the 230 contributions, only 23 papers (10%) are single authored and the rest (90%)
are multi authored. The highest number of multi- authored papers (28) were published in the year
2017. The average degree of collaboration is 0.90 during the study period, which indicates that
there was a high level of collaboration between authors. Out of the 230 research articles, the
majority (196, 85.22%) were published by Sri Lankan authors and only 14 articles (6.09%) were
published by international authors. It seems that there was a minimal collaboration of Sri Lankan
authors with foreign authors (8.70%). Authors from countries such as the United States, Japan,
Australia, Malaysia, India, Hong Kong, United Kingdom, New Zealand, Singapore, Nigeria,
Finland, Norway and Turkey have contributed to this journal. The highest number of author
contribution is from India, consisting of 20 authors followed by the United Kingdom with
contributions by 11 authors. This study concludes that the majority of the research papers are by
multi authors and by the Sri Lankan authors. The degree of collaboration indicates that there is a
high degree of author collaboration. The level of foreign collaboration is minimal. This study may
help those who wish to map the scientometric patterns of journals.
