Revisiting the concept of severe mental illness: severity indicators and healthcare spending in psychotic, depressive and dissociative disorders.

: The concept of severe mental illness (SMI) has been related to bipolar or psychotic diagnosis, or to some cases of depressive disorders. Other mental health problems such as personality disorders or posttraumatic dissociative conditions, which can sometimes lead to relevant functional impairments, remain separate from the SMI construct.: This study aimed to evaluate the clinical severity as well as healthcare spending on dissociative disorders (DDs).
