Abstract: Background In the past two decades enormously scientific
researches on posttraumatic stress disorder (PTSD) have been undertaken and
many related meta-analyses have been published. Citation analysis was used to
get comprehensive perspectives of meta-analysis articles (MA articles) on
PTSD for the purpose of facilitating the researchers, physicians and policy-
makers to understand the PTSD.
Methods MA articles on PTSD in any languages from January 1980 to March
2009 were included if they presented meta-analytical methods and received at
least one citation recorded in the Web of Science (WoS). Whereas studies, in
which any effect sizes of PTSD were not distinguished from other psychological
disorders, were excluded. Citations to and by identified MA articles were
documented basing on records in WoS. Citation analysis was used to examine
distribution patterns of characteristics and citation impact of MA articles on
PTSD. Canonical analysis was used to explore the relationship between the
characteristics of MA articles and citation impact.
Results Thirty-four MA articles published during 1998 and 2008 were identified
and revealed multiple study topics on PTSD: 10 (29.4%) were about
epidemiology, 13 (38.2%) about treatment or intervention, 6 (17.6%) about
pathophysiology or neurophysiology or neuroendocrine, 3 (8.8%) about
childhood and 2 (5.9%) about psychosocial adversity. Two articles cited most
frequently with 456 and 145 counts were published in Journal of Consulting and
Clinical Psychology by Brewin (2000) and Psychological Bulletin by Ozer (2003),
respectively. Mean cited count was 7.48 +/- 10.56 and mean age (year 2009
minus article publication year) was (4.24 +/- 2.91) years. They had been cited
approximately by 67 disciplines and by authors from 42 countries or territories.
Characteristics of meta-analysis highly correlated with citation impact and
reflected by canonical correlation of 0.899 (P<0.000 01).
Conclusions The age of MA articles predicted their citation impact. Citation
analysis would serve to capture the global perspectives and topics of MA
articles on PTSD. Chin Med J 2011;124(7):1088-1093
