This chapter summarizes the available epidemiological evidence supporting the current diagnoses grouped in the disruptive behavior disorder (DBD) cluster. It seems DBDs are common disorders, but although researchers have made great strides in capturing the prevalence of these disorders in normal and clinical populations, and although there are some very solid longitudinal findings, there are still many unknowns that need to be corrected. Most of the difficulties encountered in epidemiology are a function of the ongoing changes in the descriptive diagnostic criteria and the lack of a truly state-of-the-art three-level epidemiological design. This chapter discusses these issues including implications for clinical practice. |
