The alternative model for personality disorders (AMPD) in the defines personality functioning by assessment of impairment in Identity and Self-direction (Self component) and in Empathy and Intimacy (Interpersonal). These four domains constitute the Level of Personality Functioning Scale, a trans-diagnostic measure of PD severity. The association between the Level of Personality Functioning Scale and psychosocial impairment based on other previously established psychosocial functioning instruments has not been reported. A total of 317 individuals, including a representative clinical sample of 282 patients (192 with a personality disorder [PD] diagnosis), was evaluated with the Structured Clinical Interview for the AMPD Module I. Self-reported impairment was measured by the Work and Social Adjustment Scale (WSAS), and social and occupational impairment was assessed by the functioning score of the Global Assessment of Functioning scale (GAF-F). WSAS and GAF-F both correlated significantly with mean LPFS scores and the sum of PD criteria. For both measures, the mean LPFS was a stronger predictor for psychosocial impairment than the sum of PD criteria. Within the LPFS, the Self component was a better predictor than the Interpersonal component for both WSAS and GAF-F. For the four domains, the results diverged, with Identity as the strongest predictor by far for WSAS. Empathy was the only significant predictor for impairment evaluated by GAF-F, but its contribution to variance was not substantial. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
