162. Relations among personality dysfunction measures created before and after DSM-5 AMPD
The role of personality dysfunction in personality disorder (PD) models has received increased clinical and research attention in the last two decades. As part of the research attention, several measures of personality dysfunction have been developed. These measures divide into two groups: those developed before versus after the Alternative Model of Personality Disorder (AMPD) was introduced in Section III of DSM-5. Measures in the latter group closely follow the AMPD’s Levels of Personality Functioning Scale (LPFS) and its (sub)components of personality dysfunction: Identity and Self-direction constitute Self Pathology, whereas Empathy and Intimacy constitute Interpersonal Dysfunction. In contrast, measures in the former group assess Self Pathology and Interpersonal Dysfunction, but have differing subcomponents. Pre-AMPD personality-dysfunction measures clearly contributed to the AMPD’s conceptualization of the construct, but relations between pre- and post-AMPD measures have not been examined in research. The present project presents relations among three pre-AMPD and three post-AMPD self-report measures of personality-dysfunction in an online sample of community adults (estimated N=300). Relations between each of these six measures and maladaptive personality traits are also presented. Findings provide valuable information on the generalizability of results obtained using various personality-dysfunction measures and contribute towards a better understanding of the construct.
