Objectives: The Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition provides an alternative model for dimensional assessment of personality disorders (AMPD). In Criterion A of the alternative model, the presence and severity of personality disorders are indicated by the Level of Personality Functioning. The Level of Personality Functioning Scale–Self Report (LPFS-SR) was further developed to readily assess the construct. This study aimed to examine rudimentary reliability and validity of the translated Korean version of the LPFS-SR. Methods: A total of 395 participants completed an online survey that included the LPFS-SR and the Millon Clinical Multiaxial Inventory-IV (MCMI-IV). The present study examined internal consistency and item-total score correlations within the four components (identity, self-direction, empathy, and intimacy) of personality functioning characterized in Criterion A of the AMPD. Criterion validity was also examined for previously validated measures of personality pathology. Results: Internal consistency within the four personality functioning components of the LPFS-SR ranged from 0.80 to 0.89. Items of reversed form and contents that required interpersonal self-awareness were weakly correlated with the LPFSSR total score, while items related to general distress and dissatisfaction were strongly correlated with the LPFS-SR total score.The LPFS-SR total score was strongly correlated with MCMI-IV scales of Schizotypal, Melancholic, and Borderline, whereas compulsive and histrionic scales were minimally correlated. Partial correlations remained consistent after controlling for the effect of psychological distress, suggesting the robustness of the criterion validity. Conclusion The LPFS-SR demonstrated high internal consistency and criterion validity with extant measures of personality pathology.

Background: and Purpose: Verbal and nonverbal fluency tests are the conventional methods for examining executive function in the elderly population. However, differences in impairments result in fluency tests in patients with mild cognitive impairments (MCIs) and Alzheimer’s disease (AD) and in neural correlates underlying the tests still necessitate concrete evidence. Methods: We compared the test performances in 27 normal controls, 28 patients with MCI, and 20 with AD, and investigated morphological changes in association with the test performances using structural magnetic imaging. Results: Patients with AD performed poorly across all the fluency tests, and a receiver operating characteristics curve analysis revealed that only category fluency test discriminated all the 3 groups. Association, category, and design fluency tests involved temporal and frontal regions, while letter fluency involved the cerebellum and caudate. Conclusions Category fluency is a reliable measure for screening patients with AD and MCI, and this efficacy might be related to morphological correlates that underlie semantic and executive processing.
