What should become of depressive personality disorder in DSM-V?

Depressive personality disorder (DPD) has been under consideration for inclusion in the Diagnostic and Statistical Manual of Mental Disorders for many years. The wealth of empirical studies on the validity of DPD has raised many questions about the validity of the DPD construct and its measures. This article specifically reviews studies on the validity of that construct and how it is measured. Although the evidence supports the idea that DPD is a viable diagnostic category, there remain significant challenges to its assessment. These findings are discussed in the context of some potential changes that may occur in the classification and diagnosis of personality disorders in DSM-V.
