Abstract

Many psychological problems in adulthood have their roots in childhood and adolescence. This is particularly true for personality disorders (PDs). In order to identify young people with PD traits before their problems become pervasive, we need reliable and valid assessment tools. This volume includes three papers seeking to examine the usefulness of the Achenbach System of Empirically Based Assessment (ASEBA) for measuring PD traits in young people. Part 1 is a systematic review of cross-sectional and longitudinal studies that used the ASEBA to investigate the internalising and externalising problems of young people presenting with (or who later developed) personality difficulties. The majority of the studies examined antisocial and borderline PD. The review concluded that there was consistent evidence of criterion validity for a few ASEBA scales but the ASEBA did not have adequate psychometric properties for accurately identifying young people with PD. Part 2 is an empirical paper that used a large database created for audit purposes in a community-based psychotherapy and counselling service for young people. The ASEBA profiles of young people with PD traits and PD-related presenting problems were examined. This paper also describes the development and psychometric evaluation of two new, PD-related ASEBA scales. Finally, Part 3 is a critical appraisal of the research undertaken. It discusses epistemological and methodological aspects of the work and reflects upon the proposed changes in the conceptualisation of PD in the updated diagnostic system. This paper also highlights the clinical dilemmas related to diagnosing PD before adulthood.
