About the project
The aim of the NorAMP project is to examine the reliability, validity, and clinical utility of the Alternative Model for Personality Disorders in DSM-5 (AMPD). A total of 317 participants (282 patients and 35 non-clinical controls) were included in the cross-sectional study, which was conducted from 2014 to 2017. Level of Personality Functioning (LPF) was assessed using the Structured Clinical Interview for AMPD (SCID-5-AMPD-I). The project has resulted in a number of scientific publications. Data collection for the 8-year follow-up study took place from 2022 to 2025, with more than 140 former patients participating. The aim of the 8-year follow-up is to evaluate whether LPF can predict the clinical course and capture personality changes over time.
Can AMPD be implemented in clinical practice?
The overall aim of the project is to assess whether the AMPD can be implemented in clinical practice, and to evaluate how such an implementation may be carried out. In addition, the instruments for assessing personality functioning and personality traits are being evaluated. Since the SCID-5-AMPD-I has demonstrated good psychometric properties in a Norwegian context, the interview was published by Gyldendal in 2024. The knowledge generated through the project also has important implications for the implementation of ICD-11 in Norwegian clinical practice. In addition to examining predictive validity and personality change over time, the 8-year follow-up study aims to investigate the association between the severity of personality disorders, assessed with the SCID-5-AMPD-I, and societal costs, measured by means of a cost interview.
Funding
The project is funded by the participating health trusts: Oslo University Hospital, Sørlandet Hospital, Østfold Hospital, Haukeland University Hospital, Lovisenberg Diaconal Hospital, and Namsos Hospital. The 8-year follow-up study is partly funded through research grants from the South-Eastern Norway Regional Health Authority (PhD funding to Gaute Graasvoll).
