89. An Integrative Approach to Assessing DSM-5 Level of Personality Functioning
Personality functioning is characterized as a core feature of personality disorder (PD) and is defined in Criterion A of the Alternative DSM-5 Model for Personality Disorders (AMPD). It is operationalized using the Levels of Personality Functioning Scale (LPFS). Much of the extant literature relies on personality functioning ratings established through the use of DSM-IV PD criteria interviews or personality trait assessment and has been criticized for biasing the ratings of personality dysfunction (Cruitt et al., 2018). The current study examined the association between the clinician-rated LPFS, a self-rated measure of Criterion A, and a version of the LPFS coded based on the Life Story Interview (LSI; McAdams, 1993) in a psychiatric sample (N =153) to demonstrate the feasibility of a novel, integrative approach to characterizing personality functioning through patient narratives. The clinician-rated LPFS and the LSI narrative-coded LPFS were significantly and weakly to moderately associated (rs = 0.20-0.41). Similarly, the self-rated measure of Criterion A was also significantly and weakly to moderately associated with narrative-coded LPFS (rs =|0.20-0.41|). However, specificity across LPFS elements was not supported. This demonstrates that the LPFS is an efficient and flexible tool that can be used generally to gather information about personality problems across contexts.
