Personality Disorders 1 Running head: Personality Disorder Publications Publications Trends in Individual DSM Personality Disorders: 1971 – 2015.

The growth in personality disorder research has been documented by previous authors up to 1995. We sought to extend this by examining publications rates for individual DSM personality disorders over the period 1971-2005, and make projections to 2015 based on this data. We found that personality disorder research has grown in absolute terms, and as a proportion of overall psychopathology research. Research output is dominated by borderline personality disorder, with strong publication rates in other conditions such as antisocial and schizotypal personality disorders. In contrast, several personality disorders such as schizoid and paranoid personality disorder have failed to attract research interest. Based on current projections, there was expected to be no research output in 2015 for schizoid personality disorder. We found that the rate of publications for personality disorders was not influenced by the publication of the last three revisions of the DSM diagnostic criteria. Several potential explanations such as the difficulty in conducting certain types of personality disorder research, and the validity of the current DSM diagnostic taxonomy are discussed
