Bibliometric analysis of publications on attention deficit hyperactivity disorder (ADHD) in France since 1974

The predominance of the psychodynamic approach is often put forward to explain the delay in diagnosis and treatment of attention-deficit disorder with hyperactivity (ADHD) reported in France. A bibliometric study of abstracts, articles, or letters authored by French researchers may provide objective insight into this issue. Online electronic databases were searched without any date limits for documents related to ADHD, and allocated to the AllFR group when all authors had an affiliation in France or to the notAllFR group when at least one author had an affiliation in France. Publications expressing any psychodynamic point of view on the causes and/or treatment of ADHD were identified. A total of 747 documents were analyzed: 417 were exclusively indexed in SCOPUS, and 418 were allocated to the AllFR group. Compared with documents in the notAllFR group, documents in the AllFR group were written by a smaller number of authors (median 3 vs. 6, p<0.002), more frequently evoked psychodynamic concepts (10.45% vs. 1.67%, p<0.001), and less frequently acknowledged the persistence of ADHD in adulthood (29.10% vs. 42.14%). The psychodynamic approach was likely to rely on case reports of fewer than three children. Any serious review of the literature should pool documents from several online databases, especially SCOPUS. In publications by only French authors, the psychodynamic approach seems predominant and the persistence of ADHD in adulthood is overlooked. This may concur with the excessive delay observed in the diagnosis and treatment of children and adults in France compared to other European countries.
