The distinguishing features of Bipolar I Disorder (BD I) from Bipolar II Disorder (BD II) may reflect a separation in enduring trait dimension between the two subtypes. We therefore assessed the similarities and differences in personality traits in patients with BD I and BD II from the perspective of the Five-Factor Model (FFM).The revised NEO Personality Inventory (NEO-PI-R) was administered to 85 BD I (47 females, 38 males) and 43 BD II (23 females, 20 males) patients. All included patients were in remission from their most recent episode and in a euthymic state for at least 8 weeks prior to study entry.BDII patients scored higher than BD I patients on the Neuroticism dimension and its four corresponding facets (Anxiety, Depression, Self-consciousness, and Vulnerability). In contrast, BD II patients scored lower than BD I patients on the Extraversion dimension and its facet, Positive emotion. Competence and Achievement-striving facets within the Conscientiousness dimension were significantly lower for BD II than for BD I patients. There were no significant between-group differences in the Openness and Agreeableness dimensions.Disparities in personality traits were observed between BD I and BD II patients from the FFM perspective. BD II patients had higher Neuroticism and lower Extraversion than BD I patients, which are differentiating natures between the two subtypes based on the FFM.

The aim of this study was to explore the reliability and validity of the Korean version of the Cornell Scale for Depression in Dementia (CSDD-K), a scale for assessment of depression in dementia.The original CSDD was translated into Korean and the content was verified through back-translation procedures. This study included 59 depressive patients with Alzheimer’s disease (AD), 62 non-depressive patients with AD and 36 healthy elderly controls. The subjects were assessed using CSDD-K, the 17-item Hamilton Depression Rating Scale (HAM-D(17)), the 15-item Korean version of Geriatric Depression Scale (GDS(15)) and the Korean version of Mini-mental Status Examination (MMSE-K).In the reliability test, Cronbach’s ? coefficient and test-retest reliabilities were 0.92 and 0.91, respectively, indicating that the CSDD-K has good internal consistency. There were significant differences in CSDD-K total scores between AD patients with depression and AD patients without depression (p<0.001). In the analysis of the concurrent validity of the CSDD-K, there were significant correlations between the CSDD-K and HAM-D(17) (r=0.91, p<0.001) and between the CSDD-K and GDS(15) (r=0.75, p<0.001). ROC curve analysis identified a cut-off score of 7 for the CSDD-K, where the sensitivity was 87.5% and the specificity was 100%. Factor analysis resulted in a four-factor solution accounting for 63.8% of the common variance.The CSDD-K showed good reliability and validity for the assessment of depressive symptom severity in AD patients. The CSDD-K is a useful instrument for assessing AD patients with depressive symptoms in Korean ethnic population. HubMed – depression

Little is known about the characteristic differences in alexithymic construct in various psychiatric disorders because of a paucity of direct comparisons between psychiatric disorders. Therefore, this study explored disorder-related differences in alexithymic characteristics among Korean patients diagnosed with four major psychiatric disorders (n=388).Alexithymic tendencies, as measured by the Korean version of the 20-item Toronto Alexithymia Scale (TAS-20K), of patients classified into four groups according to major psychiatric diagnosis were compared. The groups consisted of patients with depressive disorders (DP; n=125), somatoform disorders (SM; n=78), anxiety disorders (AX; n=117), and psychotic disorders (PS; n=68).We found that substantial portions of patients in all groups were classified as having alexithymia and no statistical intergroup differences emerged (42.4%, 35.9%, 35.3%, and 33.3% for DP, SM, PS, and AX). However, patients with DP obtained higher scores in factor 2 (difficulties describing feelings) than those with SM or AX, after adjusting for demographic variables.These findings suggest that alexithymia might be associated with a higher vulnerability to depressive disorders and factor 2 of TAS-20K could be a discriminating feature of depressive disorders.
