OBJECTIVES: The aims of this study were to evaluate acceptability and usefulness of the Korean version of Self-report Standardized Assessment of Personality-Abbreviated Scale (SAPAS-SR) as an instrument for screening patients with a personality disorder. METHODS: The Korean version of the SAPAS-SR was administered to a non-random sample of 186 psychiatric patients (155 patients with a personality disorder and 31 patients with no personality disorder). The International Classification of Diseases 10th version Personality Assessment Schedule was used as a gold standard in diagnosis of personality disorder. Receiver-operant-characteristics and validity indicators were determined. In addition, the SAPAS-SR was administered to 22 healthy men to examine the test-retest reliability. RESULTS: The area under the curve for the SAPAS-SR was 0.69 (95% confidence interval 0.59-0.79). The SAPAS-SR score of 4 or more correctly classified 67.2% of patients with a personality disorder. Sensitivity (0.67) and specificity (0.68) were slightly lower compared with the original English version. CONCLUSION: This study provides preliminary evidence of the usefulness of the Korean version of the SAPAS-SR as a self-administered instrument for screening personality disorders in the clinical population.

The concept of bipolar spectrum disorder (BSD) has developed to include affective temperaments such as cyclothymia and hyperthymia. This has greatly helped clinicians to differentiate depressed patients, who would potentially benefit from mood stabilizing treatment, from those with unipolar depression. Cyclothymia, however, has significant similarities with personality disorders, especially with borderline personality disorder (BPD). All the diagnostic items for BPD are frequently found in patients with BSD as well, which presents diagnostic challenges. There are no clear guidelines on how to differentiate BSD from BPD. Featuring borderline pathology for clinical purposes, it may be useful to rely on psychodynamic approaches to identify primitive defense mechanisms of splitting and projective identification suggesting borderline personality organization. Based on new findings on common features between BSD and BPD, some authors have proposed a renewal of the classification system of mental disorders. The dichotomy of bipolar and unipolar depression has gestated a new concept of BSD. Currently, the BSD concept forced us to formulate the border of BSD and personality disorders.

OBJECTIVES: The aims of this study were to examine validity and reliability of the Korean version of the Social Function Questionnaire (SFQ) and evaluated social function with SFQ in patients with personality disorder. METHODS: The SFQ was administered to 186 psychiatric patients (155 patients with personality disorder and 31 patients without personality disorder), and 22 healthy men were recruited to examine the test-retest reliability of SFQ. The severity of personality disorders was determined using the proposed the International Classification of Diseases (ICD)-11th revision (ICD-11) personality disorders. All participants completed the NEO-Five Factor Inventory, Beck Depression Inventory, and Spielberger State and Trait Anxiety Inventory to examine the convergent validity of SFQ. RESULTS: The Korean version of the SFQ showed good internal consistency (Cronbach's alpha=0.811) and test-retest reliability (r=0.746). Patients with personality disorder had more social dysfunction than those without personality disorder. A graded increase in social dysfunction was observed with increasing severity of personality disorder. Social dysfunction showed a strong linear relationship with the 5 factor model. CONCLUSION: The Korean version of the SFQ has good psychometric properties. The results of our study support the severity classification of personality disorder integrated to upcoming ICD-11.

OBJECTIVE: The identifying schizotypal trait in obsessive-compulsive disorder (OCD) patients is important to predict clinical course, since those patients are hardly overcome through conventional intervention methods. This paper presents the trial of classification method of obsessive-compulsive disorder with schizotypal trait using Frontal Lobe Function Test (FLFT). METHODS: 110 OCD patients are divided into two groups:27 pure OCD patients, and 83 non-pure OCD patients. After training artificial neural network (ANN) using frontal-lobe function test data of train data (schizophrenia, pure OCD, and normal group), we classify test data (non-pure OCD patients) into one of the three groups. RESULTS: Among the total 83 test data (non-pure OCD patients), 44 patients were classified as schizophrenia, 32 patients as normal, and 7 patients as pure OCD. With respect to the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) data of those classified patients, ordering score in compulsion was significantly different between three groups. Moreover, cluster A socre (Schizoid, Schizotypal) of Personality Diagnostic Questionnaire (PDQ) data showed significant difference between them. CONCLUSION: The results presented that those OCD patients who are classified as schizophrenia using generated model with machine learning technique is tend to have compulsive symptom of arrangement and schizotypal personality disorder.

Up to now, it has been a prevailing concept that psychotherapy rather than pharmacotherpy is the main treatment modality for personality disorders. The use of medication to treat personality disorders has been derived from the recent confluence of anecdotal experience, a growing body of controlled studies and emerging evidence of the presence of psychobiological traits that may underlie personality disorders. Antipsychotics may be helpful for cluster A personality disorders, while antiserotonergic agents may be useful in improving mood and impulsivity for cluster B personality disorders. However data on the utility of antipsychotics and mood stabilizers are inconsistent. There have been very few studies done for cluster C personality disorders. The big problem lies in the fact that there is no consensus yet on the more fundamental areas of therapy such as classification of personality disorders, reliable measuring instruments, the relationship between axis I and axis II disorders, ruling out the effect of psychotherapy, and so on. This study reviewed the principal problems regarding the results of pharmacological treatment research of personality disorders in order to shed light on the future research directions in this area.

This study aimed to develop a Korean version of the Type D Personality Scale-14 (DS14) and evaluate the psychiatric symptomatology of Korean cardiac patients with Type D personality. Healthy control (n = 954), patients with a coronary heart disease (n = 111) and patients with hypertension and no heart disease (n = 292) were recruited. All three groups completed DS14, the Eysenck Personality Questionnaire (EPQ), the state subscale of Spielberger State and Trait Anxiety Inventory (STAI-S), the Center for Epidemiologic Studies Short Depression Scale (CESD), and the General Health Questionnaire (GHQ). The Korean DS14 was internally consistent and stable over time. 27% of the subjects were classified as Type D. Type D individuals had significantly higher mean scores on the STAI-S, CESD, and GHQ compared to non-Type D subjects in each group. The Korean DS14 was a valid and reliable tool for identifying Type D personality. The general population and cardiovascular patients with Type D personality showed higher rate of depression, anxiety and psychological distress regarding their health. Therefore, identifying Type D personality is important in clinical research and practice in chronic medical disorders, especially cardiovascular disease, in Korea.

PURPOSE: The present study investigated the validity of personality classification using four pillars theory, a tradition in China and northeastern Asia. MATERIALS AND METHODS: Four pillars analyses were performed for 148 adults on the basis of their birth year, month, day, and hour. Participants completed two personality tests, the Korean version of Temperament and Character Inventory-Revised-Short Version (TCI) and the Korean Inventory of Interpersonal Problems; scores were correlated with four pillars classification elements. Mean difference tests (e.g., t-test, ANOVA) were compared with groups classified by four pillars index. RESULTS: There were no significant correlations between personality scale scores and total yin/yang number (i.e., the 8 heavenly or earthly stems), and no significant between-groups results for classifications by yin/yang day stem and the five elements. There were significant but weak (r=0.18-0.29) correlations between the five elements and personality scale scores. For the six gods and personality scales, there were significant but weak (r=0.18-0.25) correlations. Features predicted by four pillars theory were most consistent when participants were grouped according to the yin/yang of the day stem and dominance of yin/yang numbers in the eight heavenly or earthly stems. CONCLUSION: Although the major criteria of four pillars theory were not independently correlated with personality scale scores, correlations emerged when participants were grouped according to the composite yin/yang variable. Our results suggest the utility of four pillars theory (beyond fortune telling or astrology) for classifying personality traits and making behavioral predictions.

OBJECT: This study examined the demographic characteristics, abused substance types, comorbid psychiatric diagnosis and associated crimes of substance-related offenders. METHOD: We surveyed 205 offenders of substance-related crime from court. RESULT: Substance-related offenders were all men and most of them were unemployed, living alone in the major city and mean age was 27.9+/-5.77years. 78.5% frequently abused inhalants like adhesives and 17.1% abused the methamphetamine. They violated the 1 or more times and the classification of crimes was violence, rape and rape-injury, larceny, arson. Substance-related offenders had comorbid psychiatric disorder ; 26 of them had personality disorder, 23 had mood disorder and 13 had psychotic disorder. Mean hospital day was 14.8+/-6.55 months. CONCLUSION: Substance-related offenders were young single men without a job living major city. They had comorbid psychiatric disorder and high risk to commit crime.

INTRODUCTIONThe aims of this study were two-fold; to investigate the validity and reliability of the Thai version of the Inventory of Interpersonal Problems (IIP) and to compare the characteristics of the interpersonal problems experienced in a non-clinical sample and psychiatric outpatients.

METHODSA total of 689 subjects (452 non-clinical sample and 237 psychiatric outpatients) completed the IIP-32 and IIP-64, Symptom checklist-90 (SCL-90) and 16 Personality Factor (16 PF) Questionnaire, after which a four-week retest was carried out. Cronbach's alpha was used for internal consistency and the intra-class correlation coefficient was used to determine test-retest reliability. Factor analysis of the IIP sub-scales and Pearson's correlation were used for construct and concurrent validity.

RESULTSBoth versions of the IIP showed good internal consistency. Factor analysis revealed two factors that corresponded to the circumplex property. The expected correlation between the SCL-90 and 16 PF subscales reflected the level of concurrent validity. There was a significant difference in the cold, socially-inhibited and self-sacrificing subscales between the non-clinical and clinical samples, while major depressive disorder was found to have a significantly higher score in the subscales of the control dimension, i.e. the non-assertive, socially inhibited and self-sacrificing subscales, than the neurotic and non-clinical groups, whereas, the neurotic group differed from the normative sample in terms of the affiliation axis.

CONCLUSIONThe IIP-64 and IIP-32 demonstrated their reliability and are suitable for use in either clinical or non-clinical setting.
