The new impact factor of World Psychiatry, based on citations in the year 2012 to papers published in the journal in the years 2010 and 2011, is 8.974. The impact factor of the journal was 3.896 in 2009, 4.375 in 2010, 5.562 in 2011, and 6.233 last year.
The journal is now in the top 5 of psychiatric journals, preceded only by Molecular Psychiatry, the American Journal of Psychiatry, the Archives of General Psychiatry and Biological Psychiatry.
The papers that received the highest number of citations during the period considered in the calculation of the new impact factor are the two pieces by De Hert et al on physical illness in patients with severe mental disorders (1,2); the special articles on resilience under conditions of extreme stress (3), prediction and prevention of schizophrenia (4) and long-term costs of traumatic stress (5); the research reports on self-experience in the early phases of schizophrenia (6), income-related inequalities in the prevalence of depression and suicidal behaviour following the economic crisis (7), and a randomized controlled trial of supported employment in England (8); the articles related to the development of the ICD-11 (9-12); the WPA guidance papers and recommendations (13-18); and the forums on psychiatrists as an endangered species (19), broadening the diagnosis of bipolar disorder (20), personality and psychopathology (21), and pathophysiology of schizophrenia (22-25).
The journal editorial staff is grateful to the authors, the referees and the many colleagues worldwide who made this accomplishment possible.
