This article describes the usefulness of the DSM personality disorders. In conclusion the presence of personality disorders during a lifetime is not always an enduring pattern of (the same) conduct disorders. Despite this, the DSM describes a static course of mainly interpersonal behaviour. Next to this, the utility of the DSM-Axis-II assessment and general personality assessment in relation to older adults will be discussed. In general these instruments are not very suitable for the assessment of the disposition and gravity of personality disorders in the elderly. It is proposed to develop specific profiles with regard to personality disorders in the elderly by applying the Delphi-technique on existing personality assessment. A Delphi panel of experts in the field of personality pathology in older adults can be asked to mention a certain personality disorder and describe this on a certain personality selfreport list, like the shortened version of the TCI.
