The Alternative Model of Personality Disorder (AMPD) is currently included in Section III of the Diagnostic and Statistical Manual for Mental Disorders – Fifth Edition (DSM-5). This review sought to summarise the literature concerning interrater reliability (IRR) of the AMPD. Despite high heterogeneity, meta-analysis provided tentative support for the IRR of Criterion A of the AMPD, with pooled ICCs for the Level of Personality Functioning Scale (LPFS) and its domains falling above DSM acceptability levels. Sub-group analysis of the LPFS suggested IRR scores could be improved by using a specific AMPD Structured Clinical Interview (SCI). Further research should in particular consider the IRR of Criterion B elements of the AMPD and overall PD diagnosis, where insufficient data was available to draw conclusions in the present study.
