Abstract
After decades of controversy, the concept of childhood depression now seems to be part of standard medical knowledge. Yet the form and content of this nosological entity, like many psychiatric diseases, is continuously shaped by the scientific, clinical, and political communities involved in child psychiatry. In this qualitative study, we explored how the concept of childhood depression is constructed in early twenty-first century child psychiatry. We conducted a series of 18 interviews with practising child psychiatrists, international experts in the field, and interpreted them with thematic analysis informed by discourse analysis. We identified five overarching discourse themes across interviews, relating to the definition of depression, the diagnostic process, the causes of this condition, the therapeutic strategy, and the scientific role of child psychiatry. Most participants agreed that childhood depression was a mental disorder where irritability prevailed, heavily influenced by psychosocial factors, and for which psychotherapy was the ideal treatment. However, subtle points of dissent also surfaced: whether depression is primarily a mood state or psychological suffering, whether categories or dimensions are more suitable to make the diagnosis, and whether there is a genetic predisposition were some of the most controversial topics. Theoretical considerations regarding childhood depression may have significant scientific, moral, and socio-political implications beyond child psychiatry and should be addressed appropriately.
