Publication trends in individual anxiety disorders: 1980-2015.

The aim of the current study was to examine trends in anxiety disorder publication over the past 25 years, and to project likely future trends from these. Medline searches were used to find a representative sample of the total number of journal articles published each year from 1980 to 2005 that were focused on each particular anxiety disorder. Results demonstrated that anxiety disorder research continued to grow over the 25-year period examined. Growth was particularly strong for OCD and PTSD, with strong research growth in panic disorder also in the 1980s. Only specific phobia and agoraphobia did not grow in research output over the review period. Growth is projected to continue over the next 10 years.
