Objectives:This study was designed to investigate the characteristics of personality changes and emotional distress using the Personality Assessment Inventory (PAI) in patients with traumatic brain injury(TBI), divided into mild (MTBI) and severe (STBI) groups according to the severity of injury. Methods:The subjects were consisted of 25 patients with MTBI, 25 patients with STBI, and 25 normal controls. They were interviewed with the PAI. The data were analyzed by ${\chi}^2$ test, analysis of variance and Tukey test. Results:The results were the followings. First, Negative Impression in validity scales was elevated above cutoff point(T score 70) in both MTBI and STBI groups. Second, the clinical scales of which scores elevated above the cutoff point were Somatic Complaints, Anxiety, Anxiety-Related Disorders, Depression, and Schizophrenia in the MTBI, and Somatic Complaints and Depression in the STBI. Third, the clinical subscales above the cutoff point were Conversion, Somatization, Health Concerns, Affective Anxiety, Physiological Anxiety, Traumatic Stress, Cognitive Depression, Affective Depression, Physiological Depression, Thought Disorder, and Affective Instability in the MTBI, and Health Concerns, Cognitive Depression, Affective Depression, and Physiological Depression in the STBI. Fourth, Suicide Ideation in treatment scales was the only scale above the cutoff point in the MTBI and the others of the treatment and interpersonal scales in the MTBI and all of these scales of the STBI were not elevated above the cutoff point. Fifth, the scales of which scores showed significant difference between the MTBI and the STBI were Somatic Complaints, Anxiety, Depression, and Suicide Ideation, the subscales were Conversion, Somatization, Health Concerns, Affective Anxiety, Physiological Anxiety, Physiological Depression, and Psychotic Experiences. Conclusion:These results suggest that the patients with MTBI had more somatic and anxiety symptoms, depressed mood, and suicidal ideation than the patients with STBI. These characteristics are generally consistent with clinical observation and findings from previous studies of the patients with TBI, and the PAI seems to be a beneficial adjunctive assessment tool for the evaluation of patients with traumatic brain injury.

Objective : Psychopathy has been suggested as one of the important cause of violence in patients with schizophrenia. The purpose of this study was to evaluate the personality disorder in criminal schizophrenia. Methods : A total of 187 criminal schizophrenia participated in this study. All participants filled out the Korean Inventory of Interpersonal Problem Personality Disorder Scales (K-IIP-PD), Psychopathic Personality Inventory-Revised (PPI-R), Personality Assessment Inventory (PAI). Using the correlations between the scales, we investigated whether K-IIP-PD could be used to evaluate personality disorder in criminal schizophrenia. Moreover, participants were divided into two groups of psychopathic and nonpsychopathic schizophrenics, and scores of K-IIP-PD were compared between the two subgroups. Results : The overall correlation between the scales was very high. In particular, sum of 3 item scores (interprsonal sensitivity+interpersonal ambivalence+aggression) and aggression of K-IIP-PD were highly correlated with PPI-R and PAI. Total score of personality disorder scale and subscales were higher in psychopathic schizophrenic group compared to nonpsychopathic schizophrenic group. Conclusion : The K-IIP-PD could be used to assess the antisocial and aggressive nature of criminal schizophrenia. Further studies in various clinical groups including the general population are required.

Objectives : Findings from behavioral genetics which demonstrate the high heritability of personality traits have stimulated the search for the specific genes underlying personality. A large number of association studies have investigated a correlation between serotonin transporter-linked promoter region(5-HTTLPR) polymorphism and personality traits but the results have been inconsistent. So, the aim of this study is to investigate in a large sample with homogenous background about ethnicity, gender, occupation, and age. Methods : The participants included 247 healthy Korean female adults(mean age=23.12, SD=3.22)with no history of psychiatric disorders and other physical illnesses. Genomic DNA was extracted from peripheral blood, and genotyping was performed by PCR. Personality assessment was done with the Temperament and Character Inventory(TCI). Results : Genotype Frequencies are l/l 3.6%, l/s 32.8% and s/s 63.6%(l allele:20%, s allele:80%). This low frequency of the l allele and l/l genotype was different from Caucasian results. No significant association was observed between 5-HTTLPR polymorphism and personality traits in a Korean female population. Conclusions : This study investigated the association between 5-HTTLPR polymorphism and personality traits in Korean female subjects, a large sample with homogeneous background about ethnicity, gender, occupation, and age. No significant association was observed between 5-HTTLPR polymorphism and personality traits in a Korean female population.

Purpose: The purpose of this study was to assess the association of personality characteristics with temporomandibular disorders (TMDs). Methods: Four hundred and fifty one college students in Gyeonggi-do completed the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2) and a questionnaire and collected data were analyzed by IBM SPSS Statistics ver. 25.0 software (IBM Co., Armonk, NY, USA). Results: Mean values of the number of positive answers of TMD symptoms were significantly higher in higher scorers on hypochondriasis (Hs), depression (D), paranoia (Pa) (Hs>60, D>64, Pa>59) (p<0.01). Higher scorers on Hs, hysteria (Hy), schizophrenia (Sc), Pa, psychasthenia (Pt) (Hy>64, Sc>64, Pt>64) exhibited significantly higher mean values of the number of positive answers of contributing factors for TMD (p<0.01, p<0.001). Low scorers on social introversion ($Si{\leq}44$) exhibited significantly lower mean value of the number of positive answers of contributing factors for TMD than high or moderate scorers on Si (Si>64, 45-64) (p<0.01, p<0.05). The percentage of subjects who responded that they had at least one TMD symptom was significantly higher in higher scorers on Hs, Pt, D (p<0.05, p<0.01). The significantly higher percentage of higher scorers on D, Pa reported at least one contributing factor for TMD (p<0.05). The percentage of subjects who responded that they had at least one TMD symptom or one contributing factor for TMD was significantly different among three groups divided by T-score on Si (p<0.01, p<0.05). T-scores of Hs, D, Hy, Pt and Sc showed significant correlation with the numbers of TMD symptoms and contributing factors for TMD, respectively (p<0.001). A correlation was found between T-score of Pd and the number of TMD symptoms (p<0.001). T-score of Si correlated to the number of contributing factors for TMD (p<0.001). Conclusions: Most clinical scales of MMPI-2 were found to be related to TMD. Psychological assessment including MMPI-2 may play a role in predicting treatment outcome and planning treatment of TMD.

Objective : We investigated whether Posttraumatic stress disorder patients have a higher tendency to exaggerate the extent of their psychological symptoms compared to other psychiatric patients. Methods : Medical records of patients, who had received psychiatric treatment at four university hospitals in Korea between January 2009 and December 2010, were retrospectively reviewed. We compared a group of 37 patients diagnosed with PTSD, and another group of 41 patients diagnosed with neurotic, stress-related and somatoform disorders according to the ICD-10. To compare the extent of malingering in the two groups, we compared the validity scales of MMPI-2 and Personality Assessment Inventory. We determined the number of participants in both groups feigning their responses by using various cutoff scores of the validity indicators. Results : The PTSD group showed significantly higher scores on the F (p=0.001), F (B)(p=0.000), F (P)(p=0.030), F-K (p=0.003) scale of the MMPI-2 compared to the other group of psychiatric patients. The PTSD group had a significantly higher NIM score (p=0.001) but a lower PIM score (p=0.020) of the PAI compared to the other group of psychiatric patients. Using the cutoff scores, the PTSD group showed a significantly higher number of patients who feigned responses compared to the other group ($Fb{\geq}75$ (p=0.010), $F-K{\geq}1$ (p=0.005), $F-K{\geq}10$ (p=0.011) from the MMPI-2, and $NIM{\geq}80$ (p=0.001) from the PAI). Conclusion : These results suggest that PTSD patients have a tendency to exaggerate their symptom. This group of patients overreported the severity of their condition during standardized personality assessment that included the MMPI-2 or PAI compared to patients diagnosed with other psychiatric disorders. Additional research is required to determine the factors influencing symptom exaggeration in PTSD.

Objective : The aim of this study is to evaluate the five-factor model of personality in patients with obsessive-compulsive disorder (OCD) related to obsessive-compulsive symptom severity and the distinct symptom subgroups. Methods : We recruited 95 patients with OCD and 116 normal controls in the study. We used the short version of Revised NEO Personality Inventory and the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) for the assessment. Results : Patients with OCD showed significantly higher scores in neuroticism than normal controls. On multiple linear regression analysis, we found that agreeableness and conscientiousness were associated with the total Y-BOCS scores. On subscale analysis, agreeableness and neuroticism were associated with the obsession subscale scores and only conscientiousness was associated with the compulsion subscale scores. Furthermore, we found that patients who have contamination/cleaning or symmetry/ordering/counting/arranging as a main symptom presentation had significantly higher mean scores in conscientiousness than patients who have harm due to injury/violence/aggression as a main symptom presentation. Conclusion : In this study, we found that specific personality factors are associated with the obsessive-compulsive symptom severity. In addition, this is the first study to investigate the relationship between the personality factors in the five-factor model and the distinct symptom subgroups in OCD.

Objectives: This study investigated whether the Minnesota Multiphasic Personality Inventory-Adolescent Restructured Form (MMPI-ARF) can differentiate between two groups of adolescents, one diagnosed with internalizing disorders and another with externalizing disorders, and examined the clinical utility of the MMPI-A-RF by examining which subscales can significantly discriminate between these two groups. Methods: A total of 105 adolescents aged 13-18 years completed the MMPI-A-RF (53 internalizing disorder and 52 externalizing disorder groups). Independent t-test, chi-square test (χ²), and discriminant analysis were used to examine whether MMPI-A-RF can distinguish between the two groups. Results: Sixteen MMPI-A-RF scales best predicted differences between the groups with internalizing and externalizing disorders. Fourteen scales (Higher-Order Scale [Emotional/Internalizing Dysfunction], Restructured Clinical [RC] Scale [RC demoralization, Somatic Complaints (RC1), and Low Positive Emotions (RC2)], Personality Psychopathology Five Scale [Introversion/Low Positive Emotionality-Revised, Negative Emotionality/Neuroticism-Revised], Somatic/Cognitive Scale [Malaise, Head Pain Complaints, and Gastrointestinal Complaints], Internalizing Scale [Stress/Worry, Self-Doubt], Externalizing Scale [Negative School Attitudes], Interpersonal Scale [Social Avoidance, Shyness]) were associated with the internalizing disorder group, whereas two scales (Externalizing Scale [Conduct Problems, Negative Peer Influence]) were associated with the externalizing disorder group. Conclusion: The MMPI-A-RF can be an efficient assessment tool for a quick diagnosis as it can classify individuals with internalizing and externalizing disorders in clinical settings that lack a variety of assessment tools for children and adolescents.

Objectives : The purpose of this study was to examine the factor structure of the Adolescent Personality Assessment Inventory (PAI-A) in a standardized adolescent sample using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Methods : For this purpose, three models about factor structure of the PAI-A were explored with EFA in 490 adolescents and then were evaluated with CFA in 268 young offenders. Results : The results showed that the five factor model was considered to be most appropriate for factor structures of the PAI-A in EFA. However, none of the factor models were appropriate for the factor structures of the PAI-A in CFA. Conclusion : These findings suggest that the "five factor model" is thought to explain the PAI-A the best, but further studies are needed.

Regardless of their intention, listeners tend to assess speakers' personalities based on the sounds of the speech they hear. Assessment criteria, however, have not been fully investigated to indicate whether there is any relationship between the acoustic cue of produced speech sounds and perceived personality impression. If properly investigated, the potential relationship between these two will provide crucial insights on the aspects of human communications and further on human-computer interaction. Since human communications have distinctive characteristics of simultaneity and complexity, this investigation would be the identification of minimum essential factors among the sounds of speech and perceived personality impression. The purpose of this study, therefore, is to identify significant associations between the speech sounds and perceived personality impression of speaker by the listeners. Twenty eight subjects participated in the experiment and eight acoustic parameters were extracted by using Praat from the recorded sounds of the speech. The subjects also completed the Neo-five Factor Inventory test so that their personality traits could be measured. The results of the experiment show that four major factors(duration average, pitch difference value, pitch average and intensity average) play crucial roles in defining the significant relationship.
