The relationship among three models of personality psychopathology: DSM-III-R personality disorder, TCI scores and DSQ defences

Abstract

A widely accepted clinical nosology (DSM-III-R personality disorders) rated using a clinical interview correlates reasonably predictably with two theoretical models derived from different paradigms and rated using self-reports. This might be seen as providing concurrent validity for all three models. However, serious methodological shortcomings confront studies of this type, including sample selection and measurement of personality dysfunction. One way to begin to resolve these problems is to study which personality measures are best related to treatment response and prognosis.
